This show has been flagged as Clean by the host. This is a further look at the stories of the First Doctor, portrayed by William Hartnell, during the 1960s. The First Doctor, Part 5 The Celestial Toymaker This is a wonderful story, and the Toymaker is another foe many Doctor Who fans wanted to see return, and in 2023 it happened. In the story The Giggle he returned, played this time by Neil Patrick Harris, and it is a very good story. But in this introduction of the character he is played by Michael Gough in a Fu Manchu-like costume, and he has great powers, but is bound by certain rules, which makes this interesting. When the Tardis lands in his world, he sets them games they have to survive to escape. They are games based on children's games you might be familiar with, but they have a twist. The Doctor is told he must solve the Trilogic puzzle in exactly 1023 moves, and Steven and Dodo must win their games before the Doctor wins his. This story is pure entertainment but very well done. But Hartnell's decline continued. In this story there are scenes of The Trilogic Puzzle where a hand moves a piece, but it is not Hartnell's hand, it is another actor. And Hartnell does not appear at all in episodes 2 & 3. Producer John Wiles had a plan to replace Hartnell whose contract was up at the end of the season, but he was over-ruled by BBC Head of Serials, Gerald Savory, who extended Hartnell's contract, leading to John Wiles quitting the production. Hartnell would continue for now, but something would have to happen eventually. The Gunfighters) This is another historical story, but is embarrassingly bad. It takes the Tardis to Tombstone, Arizona at the time of the famous Gunfight at the OK Corral. Steven Taylor is mostly silly trying to act out childish fantasies of cowboys. The set up comes from the end of the previous story when the Doctor bites into a candy and yells in pain. He needs to see a dentist, and Doc Holliday, aside from being a gunfighter, is a dentist. Mistaken identities happen all over. This is light fluff, but is enjoyable if you give in to the silliness. The Savages) This is another story about who are the bad guys really, similar to Galaxy Four. In this case, Dodo and Steven are captured by what appear to be Stone Age savages. The Doctor, meanwhile, is taken to the city of the Elders, is greeted warmly. It seems they have been following his travels for some time and are great admirers of him. Steven and Dodo are rescued by soldiers from the City, and reunited with the Doctor. Then Dodo slips away and stumbles on experiments being conducted on human beings. So the Elders turn out to be the real Savages here. The lab is destroyed, the two groups decide to live together in peace, but they realize they need a leader who is from neither group and choose Steven to be their leader. So another companion goes. Only Dodo is left. The War Machines This is an “AI gone bad” story. A professor has built a computer to help manage the communications in the new Post Office Tower, which in fact was a new building in London. But the computer turns out to be more than anyone realized. But Doctor gets it right away when the computer correctly gives the meaning of TARDIS. Then it turns out that the computer can hypnotize people and make them its slaves. It does this to several of the professors involved, and has them build the War Machines that will enable it to take over the world. Dodo is hypnotized and tries to trap the Doctor, but he figures it out and restores her, then she is sent away to recuperate. We won't ever see her again. Meanwhile the secretary to one of the professors, by the name of Polly, and young sailor named Ben, join up with the Doctor, and they defeat the computer. At the end, they realize they have Dodo's TARDIS key and enter just before it takes off. So now we have two new companions. This is a fun episode. The props are the usual for this time in Doctor Who, cheap. But the writing is good, and story has enough twists and turns to carry you right along. Hartnell was really good in this story despite the problems he was having. The Smugglers This is another historical story, but instead of being based on any particular incident it tells of a general occurrence in English history. The English government chose to support itself primarily through customs duties on imports, which of course created an incentive to avoid those duties by smuggling, and that definitely happened a lot in the Cornwall area. It was also one the issues that started the American Revolution, but that is not our story here. The TARDIS crew encounters a former pirate, now turned church warden, who tells them a secret before being killed by another pirate. Ben and Polly capture a man who they think is the murderer, but he is in fact an undercover Revenue agent, and in the end helps to defeat the pirates. It is a good story, and the most memorable character has to be Cherub, the pirate who murdered the church warden and who kills other people and is very sinister. This is a story where all episodes have been lost, so I had to get it through reconstructions. The Tenth Planet This is Hartnell's final story, and it takes the TARDIS to Antarctica, where the travelers are taken to the Snowcap base of the International Space Command. They are managing the return of the manned space mission Zeus IV, and everything goes wrong when a new planet appears, dooming the mission. Then we meet the second most memorable enemies of the Doctor, the Cybermen. They explain that they are from the planet Mondas, which is Earth's twin (hence the Tenth Planet), and need the energy from the Earth to keep their planet going. The General running the base is of course pig-headed and does everything possible to make things worse than they have to be. This adventure turns out to be too much for the Doctor, who explains that his old body is just wearing out, and when they get back to the TARDIS he collapses and starts to change. In the end his replaced by the of Patrick Troughton. Hartnell was becoming increasingly difficult to work with as far back as The Time Meddler, where you could really see him losing his lines, and there are lots of stories about him hiding notes to remind himself of what he was supposed to say. But the BBC didn't want the show to end, so they did something unprecedented and replaced the lead actor in a popular series. To explain it away, they invented regeneration, something the Doctor's race could do. We now call them the Time Lords of Gallifrey, but that part did not appear until the end of Troughton's run as the Doctor. For now, the Doctor was just a member of an unspecified alien race, and the only other member we had met was the Meddling Monk. At least we assume he is of the same race since he has a TARDIS. The First Doctor Era Whatever else you might want to say about Hartnell he created a franchise that has lasted for over 60 years at the time I write this. And after a slow start, he really developed the character and became identified with it. In the beginning he was a very stubborn and unlikable old man, but as the series progressed he mellowed and his humor started to come through even more. Hartnell himself returned to the role one more time in the Third Doctor story The Three Doctors (1973), which was the first time Doctor Who had a story featuring multiple incarnations of the character, in the case the First Doctor (William Hartnell), the Second Doctor (Patrick Troughton), and the Third Doctor (Jon Pertwee). But due to his declining health he has a limited role appearing only on a TV Screen. He passed away in 1975. He was portrayed by Richard Hurndall in another multiple Doctor story, _The Five Doctors_ (1983), which was broadcast for the 20th anniversary of the program during Peter Davison's run as the Fifth Doctor. In recent times David Bradley has portrayed the First Doctor, particularly in the docudrama An Adventure in Space and Time (2013) which was produced in honor of the 50th anniversary of the program. This show tells the story of the First Doctor and the how the program came together in a dramatic form, and I recommend it highly. Bradley would reprise the role in 2017 in _The Doctor Falls and Twice Upon A Time) where he played opposite Peter Capaldi's 12th Doctor, and then again in The Power of the Doctor_ (2022), where he appears alongside other previous Doctors. It is perhaps notable that the first three Doctors, William Hartnell, Patrick Troughton, and Jon Pertwee, have all passed away, but only Hartnell's First doctor has been revived so often.

This show has been flagged as Clean by the host. This series is dedicated to exploring little-known—and occasionally useful—trinkets lurking in the dusty corners of UNIX-like operating systems. Imagine, if you will, a Jane Austen novel about three sisters. The first is well-known and celebrated by everyone; the second, while slightly smarter and more capable, is significantly less popular; and the third languishes in near-total isolation and obscurity. These three sisters live on any UNIX-like system, and their names are grep , egrep , and fgrep . We will assume you are already familiar with grep — egrep works pretty much the same, except she handles e xtended regular expression syntax. (When writing shell scripts intended to be portable, be careful to call egrep if your expression uses + , ? , | , or braces as metacharacters. Some versions of GNU grep make no distinction between basic and extended regular expressions, so you may be surprised when your script works on one system but not another.) But our subject for today is poor, unnoticed fgrep . While the plainest sister of the three, she really doesn't deserve to be ignored. The "f" in her name stands either for f ixed-string or f ast, depending on who you ask. She does not handle regular expressions at all; the pattern she is given is taken literally. This is a great advantage when what you are searching for contains characters having special meaning in a regular expression. Suppose you have a directory full of PHP scripts and want to find references to an array element called $tokens[0] . You can try grep (note that the single quotes are necessary to prevent the shell from interpreting $tokens as a shell variable): $ grep '$tokens[0]' *.php But there is no output. The reason is that the brackets have special significance to grep ; [0] is interpreted as a character class containing only 0. Therefore, this command looks for the string $tokens0 , which is not what we want. We would have to escape the brackets with backslashes to get the correct match (some implementations may require you to escape the dollar sign also): $ grep '$tokens[0]' *.php parser.php: $outside[] = $tokens[0]; Instead of fooling with all that escaping (which might get tedious if our pattern contains many special characters), we can just use fgrep instead: $ fgrep '$tokens[0]' *.php parser.php: $outside[] = $tokens[0]; One place where fgrep can be particularly handy is when searching through log files for IP addresses. With ordinary grep , the pattern 43.2.1.0 would match 43.221.0.123, 43.2.110.123, and a bunch of other IP addresses you're not interested in because the dot metacharacter will match any character. To make sure you only matched a literal dot you'd have to escape each one with a backslash or, better yet, use fgrep . But what about the claim that fgrep is fast? On GNU systems, there is usually one single binary that changes its behavior depending on whether it is called as grep , egrep , or fgrep . (Actually, this is in line with the POSIX standard 1 , which deprecates egrep and fgrep in favor of a single grep command taking the -E option for using extended regular expressions and the -F option for doing fixed-string searches.) In testing, we found that when specifying a single pattern on the command line, fgrep wasn't really any faster than grep . However, when using the -f option to specify a file containing a list of a couple dozen patterns, fgrep could consistently produce a 20% time savings. On systems where grep and fgrep are different binaries, there can potentially be a more dramatic difference in speed and even memory usage. In our hypothetical Austen novel, the neglected sister would probably be driven to a bad end, to be only spoken of afterward in hushed whispers. Don't let that happen! Whenever you need to search for a string, but don't require the power of regular expressions, get into the habit of calling on fgrep . She can be very helpful and deserves more attention than she gets. You'll save yourself the trouble of worrying about metacharacters and maybe some running time as well.

This show has been flagged as Clean by the host. We'll explain why we're doing it, what it is, and cover some useful tools along the way. I've been watching movies recommended to me by my colleagues. As I work for a global company, the recommendations are often “Foreign Language”, which by definition is every movie to someone. It's often difficult to read the subtitles, or they are distracting from the acting. So I thought of converting the subtitles to speech for inclusion as an audio track, to produce a Voice Over or Lectoring audio track. Lectoring aka Voice Over Translations First used is soviet countries to read the news and propaganda from a lectors - the first podcasts ? In Polish, lektor is also used to mean “off-screen reader” or “voice-over artist”. A lektor is a (usually male) reader who provides the Polish voice-over on foreign-language programmes and films where the voice-over translation technique is used. This is the standard localization technique on Polish television and (as an option) on many DVDs; full dubbing is generally reserved for children's material. https://en.wikipedia.org/wiki/Lector#Television Example: Night of the Living Dead To give you an idea of what this sounds like I'm going to play you an example of the out of copyright movie, Night of the Living Dead . In the United States, Night of the Living Dead was mistakenly released into the public domain because the original distributor failed to replace the copyright notice when changing the film's name Original First the original sound track, then the same clip with the voice over track. Voice Over Proof of Concept As a native English speaker I find it difficult to follow those Voice Over tracks as I am trying to focus on the underlying audio. In discussions with Polish friends, it seems that this is not a problem when Polish is your native language. To put that to the test I wanted to try it out on a movie to see if that were indeed the case. I asked on Mastodon for a non English movie that was Creative Commons but did have English Subtitles, and HPR host Windigo had the answer. 2009 Nasty Old People is a 2009 Swedish film directed by Hanna Sköld, Tangram Film. It premiered on 10 October 2009 at Kontrapunkt in Malmö, and on file sharing site The Pirate Bay. The film is available as an authorized and legal download under the Creative Commons license CC BY-NC-SA. So my idea was to take each bit of subtitle text, convert it to audio, then have the generated audio play at the same time the subtitle appears on the screen. We use piper to process shows here on HPR, and we also generate srt, or SubRip subtitle files for each show. SRT or SubRip files are the easiest subtitle file to work with. From https://en.wikipedia.org/wiki/SubRip The SubRip file format is described on the Matroska multimedia container format website as “perhaps the most basic of all subtitle formats.” SubRip (SubRip Text) files are named with the extension .srt , and contain formatted lines of plain text in groups separated by a blank line. Subtitles are numbered sequentially, starting at 1. The timecode format used is hours:minutes:seconds,milliseconds with time units fixed to two zero-padded digits and fractions fixed to three zero-padded digits (00:00:00,000). The comma (,) is used for fractional separator . A numeric counter identifying each sequential subtitle The time that the subtitle should appear on the screen, followed by –> and the time it should disappear Subtitle text itself on one or more lines A blank line containing no text, indicating the end of this subtitle I downloaded the movie from the Internet Archive , and then used Piper voice to convert a minutes worth of subtitles. piper_voice: A fast and local neural text-to-speech engine that embeds espeak-ng for phonemization. GPL-3.0 license Once I had the audio prepared for a sample of the subtitles, it was over to audacity to create a new subtitle audio track. Audacity is the world's most popular audio editing and recording app GPL v2 or later, Timing the segments would be a problem, if it were not for the fact that Audacity supports srt files as Labels. File > Import > Lables. Then select the srt file The subtitle track with the text of the audio will be displayed. I could then Import each Audio segment and line them up with the subtitle track for to get the correct timing. Each subtitles segment created a new separate audio file which I then exported. I then used Kdenlive to open the video and import the audio and subtitle tracks. Kdenlive: is the acronym for KDE Non-Linear Video Editor. It works on Linux, Windows, macOS, and BSD. GPL-3.0-or-later There is a good article on adding by Jean-Marc on How to Add Subtitles Easily in Kdenlive Project > Subtitles > Add Subtitle Track Select the Subtitle file Align the subtitle and audio track. After rendering the segment out I was satisfied that this was something worth doing. The script The script can be found on the episode page for this show on the HPR site, and I put it together as a proof of concept. It creates a new audio track for the subtitles, and merges this with the original sound track to create a new selectable sound track. It begins by creating a length of silent audio that is as long as up to the first subtitle time segment begin timestamp. The first subtitle segment is converted from text to speech using Piper voice That segment of audio is added to the initial silence track. We check the total length so far, and then see if there is supposed to be silence between the last and next subtitle segment begin timestamp. If there is, then a filler piece of silence is added until the next subtitle should appear. If not then the audio for both subtitles play immediately after one another. I was worried that the subtitle audio would then lag behind the on screen dialogue but it works surprisingly well. Even long series of dialogue sort themselves out after a bit. We do this over and over again for each subtitle, right up to the very end of the movie. This new subtitle to speech audio track is then merged back into the media file as a new audio track. 96 00:15:06,240 --> 00:15:10,640 It will be two years before it's this big 97 00:15:12,840 --> 00:15:17,840 But don't you bother. By then I'll be long gone 98 00:15:19,840 --> 00:15:22,400 It was just a question 99 00:15:22,880 --> 00:15:25,480 Porridge? Original First the original sound track, then the same clip with the voice over track. Voice Over Lessons learned Now that I have done this for a lot of movies, there a few tips for getting the best output. The creation of the audio track usually goes well, but you can run into issues with the merging of the new track back into the movie. Preparation The first thing you need is a subtitle file which will be the basis of the voice you will be listening to. It should be good quality so that it matches when the actors speak. It's important to clean up this before you use it, fixing spelling mistakes and removing html that will get rendered. Listening to three hours of “I L Zero ve y Zero u”, or “less than forward slash I, greater than”, or “L am from Lndia” can get a bit tedious. You should also try and get versions that translate the songs as well. Getting a SRT file from the media. As many Subtitles are taken from a DVDs they can often be poor Optical character recognition versions of the bitmap-based streams. So a picture of string “Hello World” rather than the letters. ffmpeg By far the easiest and best way to get the subtitles is to extract it from the movie itself, provided it's a separate track. ffmpeg is a complete, cross-platform solution to record, convert and stream audio and video. LGPL-2.1-or-later, GPL-2.0-or-later https://ffmpeg.org/ ffmpeg -y -hide_banner -loglevel error -txt_format text -i "${this_movie_file}" "${this_srt_file}" Getting a SRT file from the web. If that fails you can try to get the subtitle files from the Internet. https://www.opensubtitles.org Select your language with the highest subtitle rating. You can check the media using the mpv media player. mpv is a media player based on MPlayer and mplayer2. It supports a wide variety of video file formats, audio and video codecs, and subtitle types. GPLv2+, parts under LGPLv2.1+, some optional parts under GPLv3 https://mpv.io/manual/master/ Name the srt file with the same prefix as the movie and mpv will play it. You can also use the --sub-files= option as well. mpv "${this_movie_file}" --sub-files="${this_srt_file}" Scrub through the file to see if the timing is correct. The subtitles can be toggled using the j key. Fixing Timing issues It's very important to get the subtitles to align, otherwise the voices will be out of sync. When the subtitles don't match up, it's usually that they need to have the start offset corrected. ffsubsync will automatically try and adjust the offset of the first subtitle to the first use of speech in a movie. ffsubsync: Language-agnostic automatic synchronization of subtitles with video, so that subtitles are aligned to the correct starting point within the video. MIT license https://github.com/smacke/ffsubsync pip install ffsubsync ffs video.mp4 -i unsynchronized.srt -o synchronized.srt LosslessCut will allow you to quickly remove additional trailers, or ads, at the beginning, so that ffsubsync will have a better chance of working if they are trimmed away. LosslessCut: aims to be the ultimate cross platform FFmpeg GUI for extremely fast and lossless operations on video, audio, subtitle and other related media files. GPL-2.0 license https://github.com/mifi/lossless-cut If that fails to match up the subtitles, you can use mpv keyboard shortcuts , move to the first speech segment an then press the Ctrl+Shift+Left and Ctrl+Shift+Right to adjust subtitle delay so that the next or previous subtitle is displayed. It will also show a number giving the miliseconds the delay is, eg -148416 miliseconds or -148.416 seconds. You can use many tools to adjust the subtitles, and I tried out SRT Offset . srt-offset: A simple command-line tool to offset SRT subtitle files. This tool allows you to adjust the timing of subtitles in SRT files, which can be useful when subtitles are out of sync with the video. MIT license srt-offset -i input.srt -offset -148.416 -o output.srt Manually adding the new subtitle to speech audio track If that presents an issue then you can use avidemux to just add the new audio track. Avidemux: is a free video editor designed for simple cutting, filtering and encoding tasks. GPL V2 Open Avidemux, and select “File > Open”, to select the movie. Then go to “Audio > Select Track” Select the next unselected track and tick “Enabled”, “Add Audio Track” Then pick the new mixed track, in this example .~NastyOldPeople_mixed.mp3 Conclusion I now find it much easier to watch a movie with the voice over track. It gets to a point where I don't even notice it is there and just hear the actors speak in their own language, and I just know what they are saying.

This show has been flagged as Clean by the host. 01 Introduction This episode is the eighth and final one in an 8 part series on nuclear reactor technology. In this episode I will talk about future reactor technologies, particularly what are referred to as "Generation IV" reactors. Some of these will be simply additional developments of reactors that have already been discussed in this series, but this will show what technologies are seen as most promising today. 03 What is Generation IV Generation IV International Forum is an international organization whose membership is composed of many of the countries that are researching advanced fission reactors. Their goal is to conduct a number of joint research projects to advance the state of the art. The members agree to participate in and share research on advanced technologies. 04 Research Subjects 05 Lead Fast Reactors (LFR) 08 Sodium Fast Reactor (SFR) 10 Gas-Cooled Fast Reactor (GFR) 13 Very High Temperature Reactor (VHTR) 16 Molten Salt Reactors (MSR) 19 Super Critical Water Reactors (SCWR) 27 Episode Conclusion In this episode we looked at the reactor types being studied under an international organization called the "Generation IV International Forum". All of these reactor types except for supercritical water reactors are not new and we have looked at them previously. Supercritical water reactors themselves represent the natural evolution of water cooled reactors. I expect that many of these research projects will not result in commercially successful results. Such is the nature of R&D. The supercritical water reactors would on the surface seem to have the most promise in terms of commercial use, as they focus on bringing two very well established technologies together, water cooled reactors and supercritical water. However, I'm not an expert in this field, so I'm just making an educated guess on that. 30 Series Conclusion This is the end of the series on nuclear reactor technology. Episode 1 covered nuclear basics, including basic terminology and civil versus military nuclear material. Episode 2 covered nuclear fuel, including the different types, recycling of spent fuel, uranium and thorium resources, and medical isotopes. Episode 3 covered reactor basics, including slow versus fast reactors, moderators, coolants, steam generation, refuelling methods, and the three main commercial reactor types. Episode 4 covered the less common reactor types, including types which are no longer used, some historical developmental dead ends, and some types which may possibly be making a come back. Episode 5 covered fast reactors, including the different types, some of their history, why they were developed, and why they have so far only seen limited use. Episode 6 covered thorium reactors, including what is thorium and how it differs from uranium, why there is interest in thorium, what sorts of reactors can use thorium, and why thorium has not yet seen widespread use. Episode 7 covered small modular reactors or SMRs, what the reason is for developing them, what are the different ways they may be used, and where they are currently being built. Episode 8 covered "Generator IV" reactors which is a collection of future technologies. I hope that this series has been useful and informative on how nuclear reactors work and what the different types of reactors and different types of fuel are. I have focused on the past and present without looking very much beyond what is already developed except in this final episode. I have focused on the reactors, fuel, and medical isotopes, without much discussion of mining, refining, converting, enrichment, fuel fabrication, or disposal. I also haven't talked much about the rest of a functioning power plant, which includes cooling, steam turbines, generators, transformers, control systems, refuelling systems, switch gear, transmission grid connections, grid coordination, and many, many other things. And of course there's the entire grid itself, a very complex thing when operated at scale. None the less we count on the lights going on when we turn on the light switch while seldom thinking about all the things that go on behind the scenes to make that happen. As the recent blackout in Spain shows, that is something that we can't take for granted. With plans for "Net Zero" amounting essentially to the further electrification of everything, we need reliable sources of electrical energy to make that happen. Without reliable energy available at the touch of a switch, we don't even have a stone age civilization, let alone a modern one. So think about that the next time you turn on the lights or listen to a podcast or do nearly anything else in your daily life. This concludes the eighth and final episode of an 8 part series on nuclear reactor technology. Provide feedback on this episode.

This show has been flagged as Clean by the host. I also happen to be happy when I see my dogs well. They're both a little old and have had grave sicknesses. One, the girl, is taking medication because of a problem, maybe on the spine, that interferes with walking, but in general both her and the little white male (who almost died because of stone in the ureter at around the pandemic) are today good, and I'm grateful seeing them in this state. And I suffer when they suffer. The hot weather is also more comfortable for them, so, even though we are having too much hot weeks here in Curitiba [Brazil], it's a soft, nice, weather. Generally I take a cup of coffee on the early morning. Sometimes I give a little run, or go cycling to my duties, without coffee and even without bread. Only then, hours later, I take the coffee and maybe eat something, hours after awake. The exercise, the bath with nothing on the stomach, and, oh, the coffee after (specially the espresso, or american, my current favourite, espresso with hot water), does good, it's a good feeling outside of the routine. I learned to like to share things. I like to share what I judge important. As much as I appreciate doing that, they feel as a burden; an account, or a published content, are like something I'm constantly carrying, that may condemn what I come to be, or may create expectations on others that I can't fulfil, or are “me in the world”, in a manner that I feel so unsecure. So I feel good, and safe, in erasing everything under my control some time after having created an account or published something. I feel well, and it makes me happy, to have a night of sleep in which I don't wake up more than once. If I wake up early spontaneously, and rested, better yet, good sensation, makes me happy. To be true, when I spend the first time on the morning reading the Bible, with prayer, even when I'm not keen on doing that, man, my head and my body end up being marvellous. Martin Luther, the one of the reform, is said to having said: “I have so much to do that I will spend the first three hours praying”. A piece of opinion, unasked, if you're constantly doing something you think it's too easy, you may not be doing it right, or you're not doing the right thing. Let's see what's wrong and do the right thing. One last thing that makes me happy is when my swimming pool is clean. It's been for years now. As with the other facts, it's good by itself, yeah, but has more meaning as I had many dirty problems with its water, to the point that the neighbours called sanitary authorities. I don't want to have any more problems in this area, or in any other area of living, but I know now, and have to guide my heart to feel accordingly to what I know, that any problems that arise are to result in my good and good to other people and other living creatures too. So the difficulties, even the hardest ones, can be faced with peace, because I know the future, and being in a bad state will not help in hiking up and overcoming whatever there is here now or right ahead. Our posture, our internal condition in doing something, counts much together with the external things, visible or invisible, that we do. I thank you for listening [reading]. Bye.

This show has been flagged as Clean by the host. In our next look at the game mechanics for Civilization V we examine a new feature in Civilization 5, City-States. These are independent cities controlled by the computer that are also players to some degree in the game, and you can interact with them. And they are key to winning a Diplomatic Victory. Playing Civilization V, Part 9 - City States This was a newly introduced feature in Civ 5, and they play an important role in the game. They represent the small countries that are not running the world. They do not produce Settlers, so they do not expand beyond the one city, though that city can, and will expand its borders in a similar way to how your cities can grow. They do not start with a military unit, but they can produce military units and defend themselves. They can also build buildings in the city, but not Wonders. They do have a single vote each in the World Congress (or later the United Nations), making them a key to a Diplomatic victory. City States start out neutral with regards to the players, but your interactions with them can affect how they feel about you. For example, if you send units through their territory they will get hostile, but if you give them gifts they will get friendly. And if you wish you can go to war with them and take them over. This will affect your diplomatic relations with other players and other city states, but if you have decided on a war of conquest as your victory type, that won't matter to you, right? As mentioned, if you want to go for a Diplomatic victory you want to be allied with as many of them as possible to get their votes in the World Congress or the United Nations. But even if you don't need their votes, there are other benefits from friendly relations. There are two levels to friendly relations: Friendly, and Allied, and the benefits get better as the relations improve. City State Types With the expansions there are 5 types of City State: Militaristic, Maritime, Cultured, Mercantile, and Religious. The benefits you get are: Militaristic – If you are friends the city state will periodically gift you a unit, which will appear in your city which is closest to the city state. If you are allies the units will show up more often. Maritime – If you are friends they will add two food to your Capital city. If you are allies they will add one more food to every city you have. Cultured city states share their culture with you, at one rate if you are friends and at double the rate if you are allies. Mercantile city states give you an added 3 Happiness when you are friends. If you are allies you keep the added happiness, but in addition get access to a luxury resource that cannot be obtained any other way, and that also adds Happiness. Religious city states give you a one-time bonus of Faith when you first meet them, then provide added Faith per turn. Note that Cultured and Religious city states increase the amount of Culture or Faith they provide with each new era, so the earlier you develop your relations with them the better the benefit. Managing Relations With City States There is a mechanism in the game which keeps track of points to define your relations with city states. On this numerical scale, Neutral has a value of 0, Friendly 30 or above, and Allied 60 or above. In the other direction, once you go into negative numbers they become Angry, if if you go negative enough it becomes War. A city state can only ever have one ally. If only one player has more than 60 influence points, that player will become the patron of the city state and they will ally to that player. If two or more players have more than 60 influence points, the player with the most points gets the ally. As the game goes on, you may get a message that a city state you had as an ally has suddenly allied to someone else. This is the result of the other player gaining influence points in some way, often by gifts. You can also gain influence points by promising to protect a city state, but do this with your eyes open. If you do not follow through on your promise it will enrage the city state and you will lose a lot of influence with them. Your influence with a city state has a natural resting point at 0, or Neutral. That means that barring other factors, a positive number will fall over time, and a negative number will rise over time. So if you sent one of your units through their territory they will be angry for a period, but if nothing else happens they will return to Neutral. But on the other side, you don't stay allied with them forever unless you find ways to keep adding influence points. One way is to eliminate barbarian camps near to the city state. In fact, this is one exception to the rule about sending units through their territory. If you are doing it to attack the barbarians, you are seen as a protector, not an invader, and there is no penalty. Another way to gain influence is by completing a quest from a city state. Each city state you are in contact with will periodically give you a quest, and if you fulfill it you will gain influence points. This can include killing a barbarian camp or killing nearby barbarian units (though you can do that at any time, you don't need a quest). Some others include acquiring a Great Person of a certain kind, building a certain World Wonder, bullying another city state, finding a Natural Wonder, and so on. You do not need to fulfill a quest. For example, if your strategy calls for allying with other city states, you might want to pass on bullying another city state. There is no penalty for not fulfilling a quest, just a bonus when you do fulfill one. Another way to gain influence is with gifts. The most effective is Gold, and one large sum is more effective than several small ones. For a Diplomatic victory strategy, you should plan on having a large Treasury as you approach the end game so that you can buy allies in time for the crucial vote. You can also gain a small amount of influence points by gifting units. I make it a practice to do this whenever I have units that I don't want any longer. These could be obsolete units that have no upgrade path, for instance. I don't want to pay maintenance on them as that is a drain on my Treasury, and I could just delete them, but gifting them to a city state gives me a small amount of influence. Another way to get a big jump in your influence with a city state is to capture and then a return one of their Workers. Most often this happens when a barbarian has captured the Worker, and then you capture it. You have the option of keeping the Worker for yourself, and in the early game I would probably do that because the Worker is so valuable. But at a certain point I have enough Workers, and getting the 45 influence points for returning it starts to be more effective. Remember that you have to keep earning influence points to keep up your relations, so even if you get an ally of a city state for a few turns. it will naturally decay back to Neutral. By around the middle of the game if you playing well you can start to invest the resources needed to maintain your relationships. City States and War If you are allied with a city state and you get into a war with another player, a city state you are allied with will join you in the war. Of course, the same is true for the other player, so the war between the two players could also involve 3-4 city states dragged in as allies. You cannot make peace with a city state while it is allied to a player you are at war with. You have to first make peace with that player (or wipe them out if that suits you). However, if you can get more influence with that city state and supplant the other player you can get that city state to ally with you can turn around and attack your enemy. Generally a large cash gift can do this, once again showing the utility of a fat Treasury. Exploration You cannot have diplomatic relations with a city state you haven't met, so this reinforces the idea that you have to explore the map as soon as possible. Of course, you have to balance this with other priorities, such as expanding your cities and defending them, but finding the right balance is what all the Civilization games are about. On most maps this means you should be giving some attention to developing your naval power and technologies. There seems to be a bias to city states being coastal, and in many cases they are on small islands. Of course there are a number of motivations for exploring the map. First of all, you need intelligence of what you are up against with the other players. And unless you are on a very large land mass, you will want to find added lands for settlement. Finding Natural Wonders adds to Happiness in your Empire, so finding them all is important. And last, the unexplored sections of the map have a strong tendency to spawn barbarian units against you. Early on you cannot traverse Ocean tiles and need to stick to Coastal tiles. The unit here is the Trireme, which you can build once you discover Sailing. I will usually build 1-2 Triremes in a coastal city to go around the coast of the land mass I am on and scout out the situation. If another land mass or island is sufficiently close I can cross to it without entering an Ocean tile and extend my exploration. But to really explore the whole map you need to get to Caravels. This Renaissance Era unit becomes available when you discover Astronomy, and is essentially a naval scouting unit. It can enter Ocean tiles.

This show has been flagged as Clean by the host. This is the first column in a series dedicated to exploring little-known—and occasionally useful—trinkets lurking in the dusty corners of UNIX-like operating systems. This month's column was inspired by an article on the Linux Journal web site 1 describing a custom-built script that would contain a binary tar archive and, when run, would extract the contents onto the user's system. Upon reading this, memories immediately came rushing back of the days of Usenet, before MIME-encoded e-mail made sending file attachments standard 2 , and where we walked ten miles each way to school (uphill both ways!) in three feet of snow. Yes, at that time, you had to put everything into the body of your message. But what if you needed to send a bunch of files to someone? There was tar , but the format differed between systems, and e-mail and Usenet could only reliably handle 7-bit plain-text ASCII anyhow. You could send separate e-mail messages (but what if one goes missing?) or put "CUT HERE" lines to designate where one file ends and another one begins (tedious for the recipient). The solution was a shell archive created by the shar program. This wraps all your files in a neat shell script that the recipient can just run and have the files magically pop out. All he needs is the Bourne shell and the sed utility, both standard on any UNIX-like system. Suppose you had a directory named "foo" containing the files bar.c, bar.h, and bar.txt, and wanted to send these. All you'd need to do is run the following command, and your archive is on its way. $ shar foo foo/* | mail -s "Foo 1.0 files" bob@example.com When the recipient runs the resulting script, it will create the foo directory and copy out the files onto his system. You can also pick and choose files; if you wanted to leave out bar.txt, you could do shar foo foo/bar.c foo/bar.h or, more simply, shar foo foo/bar.? . Different versions of shar have varying capabilities. For example, the BSD 3 and OS X 4 editions can only really manage plain-text files. If you had a binary object file bar.o, it'd likely get mangled somewhere along the way if you tried to include it in an archive. They also require, as in the examples above, that you name a directory before naming any files inside it (the typical way is to let the find command do the work for you; it produces a list in the right order). The GNU implementation is more flexible and can take just a directory name, automatically including everything underneath. It can also handle binary files by using uuencode—a method for encoding data as ASCII that predated the current base64 MIME standard. GNU shar rather nicely auto-detects whether the input file is text or binary and acts accordingly, and can even compress files if asked. However, unpacking encoded or compressed files from such an archive requires the recipient to have the corresponding decode/uncompress utility, and the documentation is littered with (now somewhat anachronistic) warnings about this 5 . Looking at other UNIX systems, the HP-UX version 6 also can uuencode binary files, and as a special bonus adds logic to the script that will compile and use a simple uudecode tool if the recipient doesn't already have one. It will even handle device files and put the corresponding mknod commands into the script, probably making it the most full-featured implementation of all. IBM's AIX doesn't appear to come with shar . Neither do SunOS and Solaris, which seems quite odd as original development of the program is credited to James Gosling 5 ! And so we bid farewell to shar . Next time you're considering rolling your own script for a particular purpose, consider whether such a tool might already exist, just waiting on your system for you to use it.

This show has been flagged as Clean by the host. 01 Introduction This episode is the seventh in an 8 part series on nuclear reactor technology. In this episode we will describe a topic which has been in the news in recent years, which is "small modular reactors", or SMRs for short. 03 What is an SMR? Basic Definition A small modular reactor is a nuclear reactor that is designed to be largely built in a factory and subject to as little on-site assembly as possible. The main goal is to lower costs by reducing construction times and allowing a more rapid start of return on investment. 04 Sized Based Definition Some people put a numerical size limit on SMRs, saying that they must be no larger than 300 MW to qualify as an SMR. However this limit is not universally accepted, and not all SMR designs fall within this arbitrary limit. I will ignore this numerical limit and just consider anything to be an SMR if it meets the criteria of being largely built in a factory with minimal on-site assembly. 05 The Actual Goal of the SMR Idea The actual goal of the SMR idea is to build reactors rapidly and efficiently on more or less an assembly line basis rather than hand crafting each one. One engineer in the nuclear industry has compared building reactors to building ships. Traditional shipbuilding techniques involved assembling each ship from the keel up on the slipways from individual components. 06 Newer shipbuilding techniques assemble ships as separate "blocks" inside factory-like buildings and then join completed blocks together in a final assembly stage. This requires careful planning and tight quality control, but it results in building ships much more rapidly and economically. This engineer said that SMRs are attempting to bring this newer way of doing things to the nuclear reactor industry as well. 07 SMR Categories - Small Versus Micro 08 Small SMRs 09 Small SMRs and Small Grids 10 Micro SMRs for Micro Loads 13 Micro SMRs for Large Industry 14 SMRs to Power Data Centres 15 What's This Nonsense About "Micro Small Modular Reactor" You Ask? 17 Small Reactors and Modular Reactors That Are Not SMRs 20 Standard Versus Proprietary Fuel 23 Where SMRs are Currently Being Built 24 HTR-PM in China 28 Repurposed Ship Reactors in Russia 31 300 MW BWR in Canada 33 470 MW PWR in UK 35 25 MW PWR in Argentina 37 Various Experimental SMRs 38 Modular Large Reactors 40 Conclusion SMRs are a new trend in nuclear reactor design. However, they are really two different things which fill two different needs. One style is intended to adopt designs which allow for more rapid construction with more of the work being done in the factory and less on the construction site, with the overall goal of reducing costs. The other style is to provide very small reactors to power remote communities and mines, or to provide process heat to large industries. The first SMRs are in operation or under construction. The most promising grid scale designs at present are simply scaled down and simplified conventional designs that use standard commercial fuel. Larger reactors will incorporate modular construction techniques, blurring the lines between them and SMRs. In the next episode we will talk about future reactor technologies, particularly what are referred to as "Generation IV" reactors. Provide feedback on this episode.

This show has been flagged as Clean by the host. This is a further look at the stories of the First Doctor, portrayed by William Hartnell, during the 1960s. The First Doctor, Part 4 Galaxy 4 This science fiction story is focused on the idea of not judging a book by its cover. The Tardis lands on a deserted, dying planet. They see a funny looking robot that Vicki calls a “Chumbley”. Then another one appears, and they investigate, but are rescued by three beautiful women who tell them they were in great danger, and take the three travelers back to their ship, where they meet the leader, Maaga, another beautiful woman. But somehow these women are odd and cold. They tell of how they met another ship from a evil race, the Rill, and that in a space battle the ships damaged each other and landed on this planet. Then later the travelers meet the Rill, who initially refuse to reveal their appearance because it would frighten the humans. Turns out they were very alien in appearance, but not at all evil, and it was the beautiful women who were evil. Mission to the Unknown This short little story takes place on the planet Kembel, and agents from Earth realize that the Daleks are here, and up to no good. This is really a prequel to The Daleks' Master Plan, and is notable as the only Doctor Who story in which none of the regular cast appears. The reason is that this is an extra episode slot given to the Doctor Who team late in the day, and the regular cast were already given vacation time off. So it is best to take this as Episode 0 of The Dalek's Master Plan, not as a stand-alone story. The original story has been lost, like so many episodes of early Doctor Who, but a very nice version was done by the University of Central Lancashire, and you can view it on YouTube. It is introduced by Edward de Souza, who played Marc Cory in the original, and is worth a look. They really did a good job. The Myth Makers This is another “historical” story, though instead of verified history it is historical legends at play here, in the form of the Seige of Troy by the Greeks. So you have all of the Homeric cast here: Achilles, Priam, Hector, Odysseus. The Doctor is taken for a God by Achilles, though Odysseus has his doubts. Vicki is captured by the Trojans and taken to Troy, calls herself Cressida, and is taken for a Goddess. Steven goes to Troy to try and free her, but is seen as a Greek, and so Vicki is now suspect. She falls in love with a son of Priam named Troilus, and you think something might happen here, particularly if you are familiar with play of Shakespeare called Troilus and Cressida. This story only has faint echoes of the play, preserving that Cressida is Greek and Troilus is Trojan. In this case it is Cressida staying with Troilus, so instead going back to the Tardis Vicki is now out. One more companion gone. This marked the departure of Verity Lambert as producer, and she was replaced by John Wiles. Wiles tried to implement changes, such as making the show a bit darker, but ran into opposition from both Hartnell and BBC Management, and resigned after producing four stories ( The Myth Makers through The Ark). And the popularity of other SF shows on television made a move to more SF and less history desirable. And as for Hartnell's opposition, it is notable that he had become quite identified with the role of The Doctor and was very proprietorial with it. This would come to pose problems later as his health declined. The Daleks' Master Plan This story arc takes twelve episodes, or thirteen if you add Mission to the Unknown, as you indeed should. The reason for such a long story arc is that Sir Huw Wheldon, the Director-General of the BBC at that time wanted a “monster length” Dalek story because his mother was a big Dalek fan. And this story has a lot going for it. The length means that you can do more character development. The story starts out with Steven recovering from a sword-thrust during the fall of Troy, and being attended by Katarina, a Trojan maiden, who is now in the Tardis. They arrive on the planet Kembel, and meet with Space Special Security agent Bret Vyon, played by Nicholas Courtney, who in a few years would become the beloved Brigadier Lethbridge-Stewart. Vyon tries to force the Doctor to take him to Earth so he can warn the planet, but the Doctor recognizes the Daleks and wants to find out more about their plans. And this brings us to one the most evil villains in Doctor Who, Mavic Chen. You see, the Daleks have assembled a group of villainous aliens to join together in conquering the Earth, and Mavic Chen is part of the group. He is also the idolized Guardian of the Solar System. So he is a traitor! Katarina, the Trojan maiden, sacrifices herself to save the others from a convict they meet on a prison planet. Another wonderful character is Sara Kingdom (played by Peggy Marsh), head of Space Special Security, who has been told by Mavic Chen that Vyon and the others are traitors, and who kills Vyon, who is in fact her brother! But they manage to convince her that Chen is the real traitor, and she joins them. In the middle of this story arc Christmas happened, and this resulted in the most absurd episode ever of Doctor Who, called The Feast of Steven, capped by the Doctor breaking the fourth wall. The episode is now among the missing. but you can find reconstructions on YouTube if you want to see the absurdity of it. And there is a re-appearance of The Meddling Monk. This is a sprawling story, but overall worth a look. Mavic Chen, played by Kevin Stoney, is delightfully evil, and Stoney would return to play another villain in the Troughton story The Invasion. and it is interesting to see Nicholas Courtney before he got the role he would always be identified with. Doctor Who would not do anything this large again until _The Flux_ in 2021, and frankly this story makes more sense. The Massacre of St. Bartholomew's Eve You will often see this as simply The Massacre, which is fine since there is no other story with a similar title. And after that massive science fiction story, another historical story. This involves the true story of Protestants in France being massacred by the Catholics, and the main feature worth calling our here is that William Hartnell plays two roles in this story. He is the Doctor, of course, but also the Abbott of Amboise, a leader among the Catholics looking to rid France of the Protestants. This idea of playing two parts became even more nicely done by Patrick Troughton later in Enemy of the World. In any case, this leads to confusion by Steven who thinks the Abbott is actually the Doctor. In the story a servant girl named Anna Chaplette is rescued, and this opens up the interesting possibility that she is the ancestor of Dodo (i.e. Dorothea) Chaplet, a companion who appears at the end. She witnesses a car crash, and barges into the Tardis thinking she can call the police. While the novelty of Hartnell playing two parts may stand out on first look, this story is really a showcase for Peter Purves, in his role of Steven Taylor. Because Hartnell is not on screen very much, Purves really has to carry the plot, and does so admirably. Hartnell was on vacation when the second episode was filmed, and so didn't appear at all. And his health problems were beginning cause problems which contributed to this situation. He was having a lot of trouble with remembering his lines, which is a real problem for an actor. He was not that old by current standards, as he was 58 when this story was produced, and as I am 73 as I write this, 58 seems more like late youth to me. The Ark The Tardis materializes on a spaceship in the far future. It is carrying the future of the human race to a new planet, Refusis 2, because the Earth is falling into the sun. But it also has an odd race called the Monoids, who have one eye. They are an alien race who came to Earth when their own planet was dying, and now they serve the humans. Unfortunately, the Tardis crew carries germs for which humans and Monoids on the Ark have no immunity, and sickness breaks out. One faction wants to kill the Doctor and his companions, but instead the Doctor finds a cure for the disease, and they leave on the Tardis. Then the Tardis materializes back on the Ark, but they discover that hundreds of years have passed. The Monoids have rebelled and taken over, and now the humans serve them. As the old saying has it, be kind to those you meet on the way up, for you will meet them again on the way down.

This show has been flagged as Clean by the host. Hello, dear beloveds. Here with you, at HPR: Antoine. The message of this episode is the following: life comes in waves. ~~ Circumstances are volatile. For the majority of them, we have no control of what happens. Things happen, in climate events, in health (ours or another one's), financially, emotionally. Many depend on choices that others make, or outside events that we, as humans, cannot trace cause-and-effect route — hamla ! [interjection], we can't even tell the weather precisely yet. Our emotions are subject to the same phenomenon. As far as they are tied to that events, our feelings of sadness, of relief, will come and go, also, as ~~ waves! Unpredictable, impetuous, imprecise. It ruins the health. Do you listen to your heartbeat? It can be 80 or 110 bpm from one second to another by the choices of your thinking, without you moving a muscle. A basketball player can be a better player only training in his mind, in imagination, in comparison to one that does not practice al all. Your mind, and by it we mean now the choices of your thinking, have influence in your muscular abilities and in your body chemicals. These regulate basically the entirety of your sensations, and contribute to your health or lack of it. So, when one believes, he have a stable point in which to be firm. Even though the circumstances are waves, he is not floating on them. He's anchored. That's why, if firm (true) in this faith, he's more stable and happier than an ordinary person, one that has no hope at all, but lives by what the world has to offer today. In summary, the instability is not beneficial. And we are taken to this thinking, for the pursuit of something we believe is worth it, and may be not. Then, when someone presents something we “need”, that may not be the case. We can think. Then, we choose: what we live for? How I choose to feel, and behave, because or in spite of what happens around and around? and around. No matter the point of the universe one person has reached, physically or perceptually, that does not define him for eternity. Because it is not in that past, it is happening right now, has not ended, yeah? Now, a point of experience of me. I have days of very low mood and uncertainty. The feeling of serving for absolutely nothing. (Even in good days, that may feel true, but does not define me as when I go to the ground on this thinking.) I have been said things like this, from people I value, or valued then, more than family of blood. These are days I eat not healthily, I don't have the appropriate care of my body, I don't shower. Until recently, those were days of much suffering. But I perceived that, in the next day of each of these days, in keeping trusting the hope I have, I can have a night of rest. I can wake up and take a shower, and after all start anew, having lived the bad experience the day prior as an experience that, at that moment, I only wanted to go away as soon as possible. But after going through the entirety of it, on its full duration, I would not replace this feeling-and-learning experience by anything else. Someone has said that anguish is what makes us do something. In comfort, we only go, comfortable. The purpose, or the action, comes from the need to change. Every little experience (and not only the great and abnormal) contribute to mould someone in his trajectory. Bye bye. Provide feedback on this episode.

Making First Contact An amateur radio contact, more commonly referred to as simply a "contact", is an exchange of information between two amateur radio stations. The exchange usually consists of an initial call, a response by another amateur radio operator at an amateur radio station, and a signal report. A contact is often referred to by the Q code QSO.

This show has been flagged as Clean by the host. This series is dedicated to exploring little-known—and occasionally useful—trinkets lurking in the dusty corners of UNIX-like operating systems. As the zeroth entry of this series, we'll have a little introduction to what it is supposed to be about and why you might want to listen. So that you don't leave without getting at least one piece of useful information, it will end with a little curio that you might find helpful someday. Back in 2010, I was the editor of the newsletter, titled The Open Pitt, for the Western Pennsylvania Linux Users Group in Pittsburgh. We distributed it as a two-page PDF, so had to have enough material to fill each issue. Because we were having some trouble getting contributions, I started writing columns in a series called "UNIX Curio" to occupy the empty space. They were inspired in large part by examples I had seen of people re-inventing ways to do things when utilities for the same purpose had already existed for a long time. The obvious question is: just what is a UNIX Curio? Let's start with the first word, UNIX. While a lot of people write it "Unix" instead, I have chosen to put it in all capitals because that is the way The Open Group, which controls the trademark and the certification process to use it, spells the word 1 . The history of UNIX is complex (search online for more details 2 )—the short version is that many variants emerged, often introducing incompatibilities. Even within AT&T/Bell Laboratories, two major branches came out. The Research UNIX lineage, which includes Seventh Edition (sometimes called Version 7), was often used in universities and government while System III and its more popular successor System V were clearly intended as commercial products 3 . The University of California's BSD was also very influential. My intention is to talk about things that are relatively common; ideally, they would be present on a large majority of systems so you can actually use them. Luckily, there were people who recognized the value in compatibility, so in the mid-1980s they initiated the development of the POSIX standards 4 . Publication of these not only caused commercial UNIX versions to aim for conformance—it gave Free Software implementations of utilities and operating systems a stable base to shoot for rather than having to chase multiple moving targets. As a result, today's GNU/Linux, FreeBSD, NetBSD, and OpenBSD systems generally behave as specified in POSIX, even if they haven't officially earned the UNIX or POSIX labels, so I treat them as part of the UNIX world. Moving on to the second word, "curio," it just means "an object of curiosity, often one considered novel, rare, or bizarre." There are many well-used utilities in the UNIX world, but people forget about others because they are only useful in specific circumstances. And when those circumstances arise, these obscure ones don't always get remembered. One purpose of this series is to point out some of them and describe where they can be appropriately put to use. With the flexible tools available on UNIX systems and the ability to string them together, it shouldn't be surprising that people come up with new ways to accomplish a task. I don't want to claim that these curios are always the best way to do something, just that it can be helpful to know they exist and see the way someone else solved the problem. Also, if you're using an unfamiliar system, sometimes programs you are accustomed to employing might not be installed so it's good to know about options that are widely available. So why am I the person to talk about this subject? I am not a UNIX graybeard with decades of professional computing experience. If I did grow a beard, it would only be partially gray, and my working life has been spent in the engineering world mainly around safety equipment. Sadly, there I have been forced to use Windows almost exclusively. However, in my academic and personal pursuits, I have been involved with using UNIX and Linux for more than 30 years, so I do have a bit of a historical perspective. For some reason, when I encounter an unusual or obscure tool, I want to learn more about it, especially so if I find it to be useful in some way. After gaining that information, I might as well share it with you. In addition, I have been involved with Toastmasters International, a public speaking organization, for about 15 years so I have experience in presenting things orally. I was inspired to turn this article series into podcasts by murph 5 , who delivered a presentation at the 2025 OLF Conference describing how and why to contribute to Hacker Public Radio 6 . The show notes for curios 1 through 3 will consist of the articles as they were originally written (though with references added). Because some examples, especially code, can be difficult to understand when they are read out loud, the podcasts will sometimes present the information in a different way. Show notes for this curio 0 and for curios 4 and later will be written with the podcast format in mind, so they will more closely match what I say. Let's end with an actual curio to kick off the series. Have you ever needed a quick reminder about whether the file you're looking for can be found under the /usr or /var directories? On many UNIX systems, man hier will give you an overview of how the file hierarchy is organized. This manual page is not a standard, but was present in Seventh Edition UNIX 7 and many descendents, direct and indirect, including every Linux distribution I have ever used. There are attempts to standardize the layout; in the Linux world, the Filesystem Hierarchy Standard (FHS) 8 , now hosted by Freedesktop.org 9 , intends to set a path to be followed. It should be noted that systemd has its own idea of how things should be laid out based on the FHS; if it is in use, try man file-hierarchy instead as it will likely be a more accurate description. I hope this gives you a good idea of what to expect in future episodes. The first one will be about shell archives, so keep an eye on Hacker Public Radio's schedule for it to appear.

Thorium Reactors 01 Introduction In this episode we will describe the use of thorium in nuclear power, including what thorium is, how it differs from uranium, and what sort of reactors can use it. 03 What is thorium 05 How thorium differs from uranium 07 Sources of Thorium 09 Why there is interest in using thorium as a fuel 10 Abundance of Thorium 11 Some Countries Have a Lot of It 12 Thorium Breeder Reactors are Simpler than Uranium Breeder Reactors 14 Supposed Lower Nuclear Weapons Potential 16 What is Thorium Breeding 20 Breeding Ratio 21 What sorts of reactors can use thorium 22 PHWRs - Heavy Water Reactors (Including CANDU) 24 HTR - High Temperature Gas Cooled Reactors 26 MSR - Molten Salt Reactors 29 Light Water Reactors (PWR, BWR) 31 Fast Neutron Reactors 32 The Challenges Facing Thorium Fuelled Reactors 37 Thorium in India - An Example Use Case 39 Why is India Pursuing Using Thorium? 40 How a Thorium Fuel Cycle Would Work in India 43 Current Status 46 Conclusion Thorium is an abundant material that is seen as an alternative to uranium in nuclear power. Experimental thorium power reactors date back to at least the 1960s. No new reactor technology is required to use thorium. Existing well proven reactor designs which have been in use for decades can use thorium as fuel. The common light water reactor designs that popular in some countries however are not well suited to using thorium. Initial interest in thorium was mainly driven by a perception that uranium would be in short supply in future, and slow neutron thorium reactors were cheaper and simpler than fast neutron uranium reactors. However, huge new high grade supplies of uranium were found in a number of countries, causing uranium prices to fall and reducing interest in finding alternatives. While some R&D continues on thorium fuel in a number of countries, the mainstream of development continues to be on uranium based fuel. Some countries with abundant thorium reserves though maintain a major interest in thorium, with India being the prime example. In the next episode we will describe small modular reactors.

These are the commands mentioned in the You may need to use "sudo" to run these commands depending on how your system is configured. strace uptime strace ls 2>&1 | grep open strace -e openat ls / strace ls /does/not/exist strace -o ls-trace.log ls strace -ff -o pid12345-trace.log -p 12345 HISTORY The original strace was written by Paul Kranenburg for SunOS and was inspired by its trace utility. The SunOS version of strace was ported to Linux and enhanced by Branko Lankester, who also wrote the Linux kernel support. Even though Paul released strace 2.5 in 1992, Branko's work was based on Paul's strace 1.5 release from 1991. In 1993, Rick Sladkey took on the project. He merged strace 2.5 for SunOS with the second release of strace for Linux, added many features from SVR4's truss(1), and produced a ver‐ sion of strace that worked on both platforms. In 1994 Rick ported strace to SVR4 and Solaris and wrote the automatic configuration support. In 1995 he ported strace to Irix (and became tired of writing about himself in the third person). Beginning with 1996, strace was maintained by Wichert Akkerman. During his tenure, strace development migrated to CVS; ports to FreeBSD and many architectures on Linux (including ARM, IA-64, MIPS, PA-RISC, PowerPC, s390, SPARC) were introduced. In 2002, responsibility for strace maintenance was transferred to Roland McGrath. Since then, strace gained support for several new Linux architectures (AMD64, s390x, SuperH), bi- architecture support for some of them, and received numerous additions and improvements in system calls decoders on Linux; strace development migrated to Git during that period. Since 2009, strace has been actively maintained by Dmitry Levin. During this period, strace has gained support for the AArch64, ARC, AVR32, Blackfin, C-SKY, LoongArch, Meta, Nios II, OpenRISC 1000, RISC-V, Tile/TileGx, and Xtensa architectures. In 2012, unmaintained and apparently broken support for non-Linux operating systems was removed. Also, in 2012 strace gained support for path tracing and file descriptor path decoding. In 2014, support for stack trace printing was added. In 2016, system call tampering was implemented. For the additional information, please refer to the NEWS file and strace repository commit log.

This show has been flagged as Clean by the host. In our next look at the game mechanics for Civilization V we examine several related topics: Diplomacy, Spies, and Religious Pressure. They are all ways to interact with other players without the force of arms being involved. And we will discuss the Diplomatic Victory, which is a new victory type added in Civilization V and can be fun to play. Playing Civilization V, Part 8 - Diplomacy Other Players With other players you have a relationship based on their approach to you. They are: Neutral – This is not Friendly nor is it Hostile. Trades you make with them will be fair from their point of view Friendly – They like you, and will accept requests from you more often. Trades will be slightly in your favor from their point of view. Afraid – This only happens if you have a a very substantial advantage in strength, so this is rare. They will readily accept requests from you, and trades will be in your favor Guarded – They are suspicious and defensive, and will be more likely to be unfriendly. Trades will be harder to achieve, and favor them rather than you. Deceptive – They will pretend to be friendly, but they are plotting against you. They may bribe other players to declare war on you. They will not accept requests for help, and trades will be hard to achieve. Hostile – They hate you, and are completely open about it. Trade deals, if you can get them, will be heavily against you. War – This means they have decided to go to war with you. But they need the right conditions, so they may pretend to be Friendly, Neutral, Guarded, or Hostile while they wait for those conditions to mature. These are not set in stone, as you can modify how the other player feels towards you by your actions. If you have friends in common that will improve your relationship, or if you have enemies in common. Agreeing to their requests will also improve things. But if you cannot agree, just say so. The worst negative modifier is when you agree to do something, and then do the opposite. Saying no is also negative, but not as bad. Finally, remember that negatives will erode over time if they are not reinforced. If you want a very detailed look at the mechanics and details of this, check out https://civ-5-cbp.fandom.com/wiki/Detailed_Guide_to_Diplomacy. City-States City-States are also important diplomatic partners. We'll cover all of the benefits in a different section, but here I want to focus on how they enable the Diplomatic Victory. At a certain point the United Nations will be born out of the World Congress, and when this happens a Diplomatic Victory is possible. This will occur when any player reaches the Information Era, or whenever half of the players have reached the Atomic Era. Diplomatic Victory requires that you get the votes of a certain number of delegates to the United Nations. Each player gets delegates based on their population, and there are also some additional delegates you can earn, such as through building the World Wonder Forbidden Palace which gives you two additional delegates. Anyone planning for a Diplomatic Victory should consider building this Wonder as mandatory. But each City-State gets one delegate, and if you are allied with them their delegate is yours. The mechanics of City-State relationships is that they love gifts, and cash is always the best. So anyone planning a Diplomatic Victory would be well-advised to focus on building a large Treasury. You will know when a World Leader vote is coming up in the United Nations, and can make cash drops on any City-States that are not already allied with you before the vote. But watch out that another player doesn't do the same thing after you and snipe away some of your allies. Also, you can place your spies in City-States to rig elections, and that is another way to get them to ally with you. Spies and Espionage Spies are simply awarded to you whenever any player enters the Renaissance Era. After that you receive another spy each time to advance to another Era. So you can in general have as many as 5 Spies, but if you build the National Intelligence Agency you get one more. This is a National Wonder, and should be a mandatory build if you are going for a Diplomacy victory. And England starts with 1 extra Spy, so if you play as England you could get as many as 7 Spies. Spies can be used for offense or defense. If you station one of your spies in one of your cities it can operate as a counter-spy, and may thwart or even kill an enemy spy. If you are well ahead in technology, that might be a good use, since other players will be trying to steal your tech. But if you are behind, you might want to use your spies to steal tech from other players. You may be successful in this, but the theft does not go unnoticed, and other player may use one of his spies to counter your operation. If you spy is killed, you will get another one in 3-5 turns, but if your spy was a high-rank spy with promotions, that is a serious loss, so you may want to move that spy elsewhere for a while. Diplomats When you assign a spy to the capital of another player you can designate them as a Diplomat. They will take a few turns (depends on game speed, but around 6 turns on normal speeds) to get set up. This is called “Making Introductions”, but the point is that if you need an effective diplomat, don't wait until the last minute. Diplomats can be useful in several ways. Early on, they allow you to trade votes in the World Congress. And they will bring you intelligence about intrigues, and you can then share that with other players. And it can also give you a view of the other player's City Screen. Once you have researched Globalization your Diplomats can help with a Diplomatic Victory because each one counts as one additional vote in the United Nations for World Leader. You can change a spy into a Diplomat and vice versa just by moving the Spy/Diplomat from its current location to another location, which will trigger the ability to change the job assignment. This means that when you first get Spies, and they cannot yet be used to get additional Delegate votes as Diplomats, you can assign them to City-States, where they can help you get alliances. Then as you start to research Globalization, move them to the capitals of other players and turn them into Diplomats. This of course assumes you want to win a Diplomatic victory. If instead you are going for a Science victory and are ahead in Science, it is probably best to station them in your own cities to do counter-intelligence work. If you are ahead in Science, other players will be trying to steal tech from you. Religious Pressure If you have researched all of the Piety Social Policy Tree, you will have option to choose a Reformation Belief to add to your religion. One of these, Underground Sect, allows your spies to exert religious pressure against the city they have been sent to. However, this effect is fairly small. If there is not a Follower of your religion in the city, it seems to do nothing. But in combination it can flip cities to your religion. Start by sending in a Missionary to spread your religion, then your spy can add to that. And you should also combine that with a trade route to add additional religious pressure. And by gradually moving your spies, missionaries, and trade routes from city to city, you can make your religion dominant in a region. Diplomatic Victory This can be a fun way to win, and I have done it. If you want to get a leg up, start with a Civ that gives you advantages, such as Greece or Venice (although my last diplomatic Victory was achieved with Ethiopia, which is generally regarded as a military/domination Civ. You can win any victory type with any civ, and it can be fun to “play against type”). Greece gets an advantage from relations with City-States, which are key to a Diplomatic Victory because each one gets a vote for World Leader. And Venice is interesting because you cannot build settlers. But you can use cash to puppet City-States, and you can purchase units in puppeted City-States as well. Cash is king in the Venice strategy, and you will want to get as many Trade Routes as possible. The first two should send Food to Venice to help boost your population. Since you will only ever have one city as Venice you will want to max it out. All trade routes after that should focus on cash. Use your cash to purchase or upgrade military units, and employ a defensive strategy. You want enough military to deter any aggression against you, but you should avoid making any hostile moves against others if possible. Remember, this is a strategy for a Diplomatic Victory. If you want to go to war, don't choose Venice. Instead choose one of the Domination Civs, like the Zulus or the Mongols.

This show has been flagged as Clean by the host. Create a Linux kiosk at your library Start without a guest account The first few steps of this process don't actually require a guest user directory to exist, so do NOT create your guest user account yet. However, you do need to choose what your guest user account is going to be called. A reasonable account name for Don's purposes is libraryguest. On my personal computer I call my guest account guestaccount, and I've used kioskguest on some installations. I avoid just the name “guest” because in modern computing the term “guest” gets used in a few other ways (such as a “guest operating system” in a virtual environment), and it's just easier to find something unique in logs. Choose a unique name for you guest account, but don't create it yet. For this article, I'm using libraryguest. Create the PostSession script By default, GDM recognises several states: Init, PostLogin, PreSession, and PostSession. Each state has a directory located in /etc/gdm. When you place a shell script called Default in one of those directories, GDM runs the script when it reaches that state. To trigger actions to clean up a user's environment upon logout, create the file /etc/gdm/PostSession/Default. You can add whatever actions you want to run upon logout to the Default script. In the case of Don's library, we wanted to clear everything from the guest's home directory, including browser history, any LibreOffice files or GIMP files they may have created, and so on. It was important that we limited the very drastic action of removing all user data to just the guest user. We didn't want the admin's data to be erased upon logout, so whatever rule we added to /etc/gdm/PostSession/Default had to be limited to the guest user. Here's what we came up with: #!/usr/bin/sh echo "$USER logged out at `date`" >> /tmp/PostSession.log if [ "X$USER" = "Xlibraryguest" ]; then rm -rf "$HOME" fi exit 0 The first line is for logging purposes. The /tmp directory gets cleared out on most distributions automatically, so we weren't worried about creating a file that'll grow forever and eventually crash the computer. If your distribution of choice doesn't clean out /tmp automatically, create a cron job to do that for you. GDM knows what user triggered the logout process, so the if statement verifies that the user logging out is definitely the libraryguest user (that's the literal name of the user we created for library patrons).Note that the whitespace around the square brackets is important, so be precise when typing! As long as it is libraryguest, then the script removes the entire user directory ($HOME). That can be extremely dangerous if you make a mistake, so do thorough testing on a dummy system before implementing a script like this! If you get a condition wrong, you could erase your entire home directory upon logout. In this example, I've successfully limited the rm command to a logout action performed by user libraryguest. The entire /home/libraryguest directory is erased, and the computer returns to the GDM login screen. When a new user logs in, a fresh directory is created for the user. You can put any number of commands in your script, of course. You don't have to erase an entire directory. If all you really want to do is clear browser history and any stray data, then you can do that instead. If you need to copy specific configuration files into the environment, you can do that during the PreSession state. Just be sure to test thoroughly before committing your creation to your users! What happens when the guest doesn't log out At this point, the computer erases all of the user's data when the user logs out, but a reboot or a shutdown is different to a logout. GDM doesn't enter a PostSession state after a reboot signal has been received, even if the reboot occurs during an active GDM session. The easiest and safest way to erase an entire home directory when there's a cut to system power is to use a temporary RAM filesystem (tmpfs) to house the data in the first place. If the systems you're configuring have 8 GB or more, and the system is exclusively used as a guest computer, you can probably afford to use RAM as the guest's home directory. If your system doesn't have a lot of RAM, then you can use the systemd work-around in the next section. Assuming you have the RAM to spare, and that your systems are supported by a backup power supply, you can add a tmpfs entry in /etc/fstab. In this example, my tmpfs is mounted to /home/libraryguest and is just 2 GB: tmpfs /home/libraryguest tmpfs rw,nosuid,nodev,size=2G 0 0 That's plenty of space for some Internet browsing and even a few LibreOffice documents to be saved while a user works. Mount the new volume: $ sudo mount /home/libraryguest Next, you must create the libraryguest user manually in a terminal.The useradd command creates user profiles: $ sudo useradd --home-dir /home/libraryguest libraryguest useradd: warning: the home directory /home/libraryguest/ already exists. useradd: Not copying any file from skel directory into it. Because you've already created a location for the home directory, you do get a warning after creating the user. It's only a warning, not a fatal error, and the guest account is automatically populated later. Create a password for the new user: $ sudo passwd libraryguest That's it! You've created a guest account that refreshes with every logout and every reboot. You can skip over the next section of this article. Using systemd targets instead of a ramdisk Assuming you can't create a ramdisk for temporary user data, you can instead create a systemd service that runs a script when the reboot, poweroff, and multi-user targets are triggered: [Unit] Description=Kiosk cleanup [Service] Type=oneshot ExecStart=/usr/local/bin/kiosk-cleanup.sh [Install] WantedBy=poweroff.target reboot.target multi-user.target Save the file to /etc/systemd/system/kioskmode.service and then enable it: $ sudo systemctl enable --now kioskmode The script, like the GDM script, removes the libraryguest directory. Unlike GDM script, this one must also recreate an empty home directory and grant it user permissions: #!/usr/bin/bash rm -rf /home/libraryguest mkdir /home/libraryguest chown -R libraryguest:libraryguest /home/libraryguest Grant the script itself permission to run: $ sudo chmod +x /usr/local/bin/kiosk-cleanup.sh Now the libraryguest user data is erased after: Logout Reboot Shutdown Startup Essentially, no matter how the computer loses its session or its power, the libraryguest account starts fresh when a new session is started. Security and privacy Using systemd to erase data at shutdown and startup isn't strictly as secure as using a temporary ramdisk for all user data. Should the computer lose power suddenly, all saved user data in the libraryguest account is present during the next boot. Of course, it's erased as soon as multi-user.target is called by systemd, but it is technically possible to interrupt the boot process and mine for data. You must use full drive encryption to protect data from being discovered by an interrupted boot sequence. Why not just use xguest On many Linux distributions, the xguest package is designed to provide the Guest account, which resets after each logout. It was an extremely useful package that I installed on every machine I owned, because it's handy to be able to let friends use my computer without risking them making a mess of my home directory. Lately, it seems that xguest is failing to launch a desktop, however, presumably because it relies on X11. If xguest works for you in your tests, then you may want to use it instead of the solution I've presented here. My solution offers a lot of flexibility, thanks to GDM's autodetection of session states. Kiosks in libraries Privacy and personal information is more important than ever. Regardless of how you setup a kiosk for your library, you have an obligation to your users to keep them informed of how their data is being stored. This goes both ways. Users need to know that their data is destined to be erased as soon as they log out, and also they deserve to be assured that their data is not retained. However, it's also your responsibility to admit that glitches and exceptions could occur. Users need to understand that the computer they're using are public computers on a public network. Encryption is being used for traffic and for data storage, but you cannot guarantee absolute privacy. As long as everyone understands the arrangement, everyone can compute with confidence. Linux, GDM, and systemd are great tools to help libraries create a sustainable, robust, honest, and communal computing platform. Show notes taken from https://www.both.org/?p=13327

We were four sitting in the room and it was this one terminal for all of us and maybe even for someone more. Downstairs, we at component technology department had our big climate controlled laboratories. I used an HP 85 computer having the Basic programming language to automize measurements of resistors. And there were several more of them for other measurements of various electronic components. Also more advanced computers were used in the labs and as I recall also with other languages than Basic. I remember I learned briefly a bit about one of those languages but have forgotten which one. The secretary at the department could send Telex messages around the world. We handed a hand written manuscript to her and she typed it into the Telex system. And she had a Xerox computer with big, at least the 8 inch floppy discs. Not so many years later my manager got a Personal computer running DOS and some years later it DOS computers also to the staff. But also very early we had a Sun Unix station. And for many years Unix became my daily driver at work. Before I started to work, in school we had some education in Basic programming. We were using the at least in Sweden very successful and good Luxor ABC 80 computer. At the end of my school time, my school got the top notch ABC 800 with colour screen. At home so I could get a chance to learn somewhat more about computers and Basic programming in my own pace, I got a Zinclair ZX 80 computer, which I later upgraded to ZX 81. One summer job when I was a student I was at Televerket, the Swedish PTT. It meant that I visited numerous of exchange stations. Many at the country side, some with very few subscribers so I could hear the relay start when someone was making a call. At bigger stations it was noise from relays all the time. As I mentioned, after studies were completed I was working with telecom equipment in particular for land line telephony. Not at least I worked with components for the line cards, the card at the telephone exchange that is facing towards the end user. The book The_Cuckoo's_Egg is a hacker thriller based on a true story that happened in the mid-1980's going on for a year. It was written by the hunter shortly after. Cliff Stoll describes Unix commands, which are similar to Linux. He talks about passwords, about encryption and a lot more. Many technical details he describes by using analogy with more common non technical life examples. A security hole in GNU-Emacs software, a software still around today, plays a central role in how the hacker could penetrate. To fix and update security holes are very relevant today as well. Many things in computers and technology have changed. But at the same time very much of the problems are valid today although they are somewhat different. And the way he describes technical details for the non-technical reader are relevant also today, I believe. At the same time as the book has many technical details, he also describes the daily life at home, the left wing culture he belonged to at the university, his long hair and the dress code he belonged to. And the music. He also describes his contacts to numerous authorities and frustration in those contacts. I am very impressed of his analytical research approach, his persistence, his skills and inventiveness including inventiveness of his girl friend and others. One take away for me is that he kept a detailed log book. It is an important research tool. The log book together with the print outs of exactly what the hacker did were core references for analyzing and make conclusions, retract and change conclusions when new information lead to that earlier assumptions were wrong.

This is as opposed to "slow" or "thermal" neutron reactors which use a slow neutron reaction. Nearly all reactors in use today use a slow neutron reaction. 04 Moderators 06 No Moderator in Fast Neutron Reactors 07 Burners versus Breeders 08 Fast Fission Fuel Cycle 08 "Typical" Fuel 09 Other Methods 10 Reprocessing 11 Fuel Types 11 Oxide 12 Metal 13 Nitride 14 Carbide 15 Coolant 16 Liquid Sodium 18 Liquid Lead or Lead-Bismuth 19 Helium Gas 20 Molten Salt 21 History of Fast Neutron Reactors 21 Origins 22 Reasons for Developing Them 23 Reasons They are Still Being Developed 24 This is a Proven Technology 25 Plutonium Stockpiles 26 Pros and Cons of Fast Reactors If fast reactors are more expensive and difficult to operate than slow reactors, why is there any interest in them? 27 Pros Fast neutron reactors can use all of the uranium supply by converting the U-238 to plutonium as well as using the U-235. Slow neutron reactors can only use the U-235 plus converting a very small proportion of the U-238 to plutonium. This means that a given amount of fuel will go much further when used with a fast neutron reactor than a slow one. 28 Some (but not all) fast neutron reactors can produce more plutonium than they use. This extra plutonium can be used to make uranium-plutonium mixed oxide (or MOX) fuel to be used in slow reactors, or it can be used to power a thorium fuel cycle. So the higher cost of the fast neutron reactors can be offset by having it produce fuel for several slow neutron or thorium reactors. 29 They can also use up or "burn" radioactive waste. That is, highly radioactive elements which are a byproduct of fuel use but not usable as fuel by themselves can be separated from the spent fuel and fed back into the reactor where the additional radiation will convert them into elements or isotopes which are either not radioactive or which are otherwise easier to dispose of. 30 Cons There are a number of cons however, as otherwise there would be a lot more fast neutron reactors in the world. Since water, even "light" water, is a moderator, fast neutron reactors cannot use water as a coolant. Other alternative coolants must be used, and these complicate the design of the reactor and make it more difficult to operate. 31 Alternative compatible coolants may be corrosive, and so new materials may need to be developed for both the reactor vessel and the fuel cladding. Alternative coolants are often opaque, making it difficult to inspect the reactor. The fuel cycle requires reprocessing spent fuel, which means that reprocessing facilities have to be set up, which is an additional expense. 32 Fast neutron reactors were primarily developed on the premise that uranium supplies were limited and would soon become very expensive. However new very large and very high grade uranium deposits were discovered in Canada, Australia, and Kazakhstan, causing uranium prices to fall rather than rise. As a result it is much cheaper to operate a once-through fuel cycle than to build fast neutron reactors. 33 Future Prospects Currently fast neutron reactors are not economically competitive with slow neutron reactors for electric power generation so there isn't a lot of interest from prospective customers. Originally interest in them was driven by a belief that the world would run short of uranium. However, higher uranium prices sparked increased mineral exploration which resulted in finding large high grade reserves of low cost uranium, undercutting the need for economizing on its use. 34 There is still ongoing R&D though as they offer several other use cases. One is to get rid of radioactive waste elements by turning them into non-radioactive or less radioactive isotopes or elements. The other is to provide a supply of plutonium for fuelling thorium reactors. 35 Conclusion This has been a short overview of fast neutron reactors, including their history, uses, and underlying design features. In the next episode we will describe the use of thorium in nuclear power, including what thorium is, how it differs from uranium, and what sort of reactors can use it.

I've written code to ensure that metadata for a company's custom file format gets copied along with the rest of the data when the file gets archived, code that ensures a search field doesn't mangle input, lots of Git hooks, file converters, parsers, and of course my fair share of dirty hacks. Because most software projects I work on are designed for a specific task, very few of them have required packaging. My utilities have been either integrated into a larger code base I'm not responsible for, or else distributed across an infrastructure by an admin. It's like a magic trick, which has made my life conveniently easier but, as magic does, it has also tricked me into thinking that my development work is done once I can prove that my code does its job. The reality is that code development isn't actually done until you can deliver it to your users in a format they can install. I don't think I'm alone in forgetting that software delivery is the real final product. There are many reasons some developers stop short of providing an installable package for the code they've worked on for weeks or months or years. First of all, packaging is work, and after writing and troubleshooting code for months, sometimes you just want your work to be over just as soon as everything functions as expected. Secondly, there are a lot of software package formats out there, regardless of what platform you're delivering to. However, I view packaging as part of quality assurance. There are lots of benefits you gain by packaging your code into an installer, and you don't have to target every package format. In fact, you get the benefits of packaging by creating just one package. Checking for consistency When you package your code as an installable file, whether it's an RPM file or a Bash script or a Flatpak or AppImage or EXE or MSI or anything else, you are checking your code base for consistency. Pick whatever package format you're most comfortable with, or the one you think represents the bulk of your target audience, and you're sure to find that the package tooling expects to be automated. Nobody wants to start packaging from scratch every time they update code, so naturally packaging tools are designed to be configured once for a specific code base and then to create updated packages each time the code base is updated. If you're building a package for your project and discover that you have to manually intervene, then you've discovered a bug in your code. Imagine that you've got a project repository with a name in camel-case. You hadn't noticed before, but your code refers to itself in a mix of lowercase and camel-case. Your package build grinds to a halt because a variable used by the packaging tools suddenly can't find your code base because it was set to a lowercase title but the archive of your code uses camel-case. If this happens to you, it's also going to happen for every software packager trying to help you deliver your project to their users. Fix it for yourself, and you've fixed it for everyone. Discover surprise dependencies For decades, one of the most common problems of software troubleshooting has been the phrase “well, it works on my machine.” No matter how many tools we developers have at our disposal to make it easy to build and run software on a clean system, it's still common to accidentally deliver software with surprise dependencies. It's easy to forget to revert to a clean snapshot in a virtual machine, or to use a container that just happens to have a more recent version of a library than you'd realised, or to get the path of an important executable wrong in a script, or to forget that not all computers ship with a thing you take for granted. Not all packaging tools are immune to this problem, but very robust ones (like RPM and DEB, Flatpak, and AppImage) are. I can't count the times I've tried to deliver an RPM only to be reminded by rpmbuild that I haven't included the -devel version of a dependency (many Linux distributions separate development libraries from binaries.) You may not literally fix every problem with dependency management by building a single package, but you can clearly identify what your code requires. It only takes a single warning from your packaging tool for you to add a note to other packagers about what they must include in their own builds. As an additional bonus, it's also a good reminder to double check the licenses your project is using. In the haze of desperate hacking to get something to just-work-already, it's helpful to get a gentle reminder that you've linked to a library with a different license than everything else. Few packaging tools (if any?) detect licensing requirements directly, but sometimes all it takes is a reminder that you're using a library that comes from a non-standard repo for you to remember to review licensing. Every package is an example package Once you've packaged your code once, you create an example for everyone coming to your project to turn it into a package of their own. It doesn't matter whether your example package is an RPM or a DEB or just a TGZ for a front-end like SlackBuild or Arch's AUR, it's the interaction between a packaging system and the input script that counts. Even a novice package maintainer is likely to be able to reverse engineer a packaging script enough to reuse the same logic for their own package. Here's the build and install section of the RPM for GNU Hello: %prep %autosetup %build %configure make %{?_smp_mflags} %install %make_install %find_lang %{name} rm -f %{buildroot}/%{_infodir}/dir %post /sbin/install-info %{_infodir}/%{name}.info %{_infodir}/dir || : Here's the GNU Hello build script for Arch Linux: source=(https://ftp.gnu.org/gnu/hello/$pkgname-$pkgver.tar.gz) md5sums=('5cf598783b9541527e17c9b5e525b7eb') build(){ cd "$pkgname-$pkgver" ./configure --prefix=/usr make } package(){ cd "$pkgname-$pkgver" make DESTDIR="$pkgdir/" install } There are differences, but you can see the shared logic. There are macros or functions that abstract some common steps of the build process, there are variables to ensure consistency, and they both benefit from using automake as provided by the source code. Armed with these examples, you could probably write a DEB package or Flatpak ref for GNU Hello in an afternoon. Package your code at least once Packaging is quality assurance. Even though a packaging system is really just a front-end for whatever build system your code uses anyway, the rigour of creating a repeatable and automated process for delivering your project is a helpful exercise. It benefits your project, and it benefits the people eager to deliver your project to other users. Software development isn't over until it's packaged.Shownotes taken from https://www.both.org/?p=13264Provide feedback on this episode.

This show has been flagged as Clean by the host. This brings us to a look at some of Arthur C. Clarke's other stories, A Time Odyssey (1951), Tales From the White Hart (1957), The Nine Billion Names of God (1954), The Star (1955), Dolphin Island (1964), and A Meeting With Medusa (1971. These stories will wrap up our look at Clarke's Science Fiction and we have seen a lot of good stuff here. And as a final note, we cover CLarke's Three Laws. Arthur C. Clarke: Other Works, A Time Odyssey A collaboration between two of science fiction's best authors: what could possibly go wrong? Well, something went wrong. This series is not bad, but I hesitate to describe it as good. This series was described by Clarke as neither a prequel nor a sequel, but an “orthoquel”, a name coined from “orthogonal”, which means something roughly like “at right angles”, though it is also used in statistics to denote events that are independent and do not influence each other. And in relativity theory Time is orthogonal to Space. And in multi-dimensional geometry we can talk about axes in each dimension as orthogonal to all of the others. It is something I can't picture, being pretty much limited to three dimensions, but it can be described mathematically. It is sort of like the 2001 series, but not really. It has globes instead of monoliths. And the spheres have a circumference and volume that is related to their radius not by the usual pi, but by exactly three. Just what this means I am not sure, other than they are not sphere's in any usual sense of the word. In this story these spheres seem to be gathering people from various eras and bringing them to some other planet which gets christened “Mir”, though not in any way to the Russian Space Station. It is a Russian word that can mean “peace”, “world”, or “village”. I have seen it used a lot to refer to a village in my studies of Russian history. Anyway, the inhabitants include two hominids, a mother and daughter, a group of British Redcoats, Mongols from the Genghis Khan era, a UN Peacekeeper helicopter, a Russian space capsule, an unknown Rudyard Kipling, the army of Alexander The Great… Well at least they have lots of characters to throw around. They end up taking sides and fighting each other. In the end several of the people are returned to Earth in their own time. But the joke is on them. The beings behind the spheres are call themselves The Firstborn because they were the first to achieve sentience. They figure that best way for them to remain safe is to wipe out any other race that achieves sentience, making them to polar opposite of the beings behind the monoliths in 2001, for whom the mind is sacred. Anyway, the Firstborn have arranged for a massive solar flare that will wipe out all life on Earth and completely sterilize the planet, but conveniently it will happen in 5 years, leaving time for plot development. Of course the people of Earth will try to protect themselves. Then in the third book of the series an ominous object enters the solar system. This is of course a callback to the Rama object. It is like they wanted to take everything from the Rama series and twist it. While I love a lot of Clarke's work and some of Baxter's as well, I think this is eminently skippable. The two of them also collaborated on the final White Hart story, which isn't bad Other Works Tales from the White Hart This collection of short stories has a unity of the setting, a pub called White Hart, where a character tells outrageous stories. Other characters are thinly disguised science fiction authors, including Clarke himself. Clarke mentions that he was inspired to do this by the Jorkens stories of Lord Dunsany, which are also outrageous tall tales, but lacking the science fictions aspects of Clarke's stories. Of course this type of story has a long history, in which we would do well to mention the stories of Baron Munchausen, and of course the stories of L. Sprague de Camp and Fletcher Pratt as found in Tales from Gavagan's Bar. And Spider Robinson would take this basic idea and turn it into a series of books about Callahan's Place. Stories of this type are at least as much Fantasy as anything, but quite enjoyable, and I think I can recommend all of these as worth the time to while away a cold winter's evening while sitting by a warm fire with a beverage of choice. The Nine Billion Names of God This short story won a retrospective Hugo in 2004 as being the best short story of 1954. The idea is that a group of Tibetan monks believe that the purpose of the universe is to identify the nine billion names of God, and once that has been done the universe will no longer have a purpose and will cease to exist. They have been identifying candidates and writing them down, but the work is very slow, so they decide that maybe with a little automation they can speed it up. So they get a computer (and in 1954, you should be picturing a room-sized mainframe), and then hire some Western programmers to develop the program to do this. The programmers don't believe the monks are on to anything here, but a paycheck is a paycheck. They finish the program and start it running, but decide they don't want to be there when the monks discover their theory doesn't work, so they take off early without telling anyone, and head down the mountain. But on the way, they see the stars go out, one by one. The Star This classic short story won the Hugo for Best Short Story in 1956. The story opens with the return of an interstellar expedition that has been studying a system where the star went nova millennia ago. But the expedition's astrophysicist, a Jesuit Priest, seems to be in a crisis of faith. And if you think it implausible that a Jesuit Priest could also be an astrophysicist, I would suggest you look into the case of the Belgian priest Georges Lemaître, who first developed the theory of the Big Bang. Anyway, in the story, they learn that this system had a planet much like Earth, and it had intelligent beings much like Earth, who were peaceful, but in a tragic turn of events they knew that their star was going to explode, but they had no capability of interstellar travel. So they created a repository on the outermost planet of the system that would survive the explosion, and left records of their civilization. And when the Jesuit astrophysicist calculated the time of the explosion and the travel time for light, he is shaken: “[O]h God, there were so many stars you could have used. What was the need to give these people to the fire, that the symbol of their passing might shine above Bethlehem?” Dolphin Island This is a good Young Adult novel about the People of the Sea, who are dolphins. They save a young boy who had stowed away on a hovership that subsequently had crashed, and because no one knew about him he was left among the wreckage when the crew takes off in the life boats. And from here it is the typical Bildungsroman you find in most Young Adult novels. The dolphins bring him to an island, where he becomes involved with a research community led by a professor who is trying to communicate with dolphins. He learns various skills there, survives dangers, and in the end has to risk his life to save the people on the island. If you have a 13 year old in your house, this is worth looking for. A Meeting With Medusa This won the 1972 Nebula Award for Best Novella. It concerns one Howard Falcon, who early in the story has an accident involving a helium-filled airship, is badly injured, and requires time and prosthetics to heal. But then he promotes an expedition to Jupiter that uses similar technology, a Hot-Hydrogen balloon-supported aircraft. This is to explore the upper reaches of Jupiter's atmosphere, which is the only feasible way to explore given the intense gravity of this giant planet. Attempting to land on the solid surface would mean being crushed by the gravity and air pressure, so that is not possible. The expedition finds there is life in the upper clouds of Jupiter. Some of it is microscopic, like a kind of “air plankton” which is bio-luminescent. But there are large creatures as well, one of which is like jellyfish, but about a mile across. This is the Medusa of the title. Another is Manta-like creature, about 100 yards across, that preys on the Medusa. But when the Medusa starts to take an interest on Falcon's craft, he decides to get out quick for safety's sake. And we learn that because of the various prosthetics implanted after the airship accident Falcon is really a cyborg with much faster reactions than ordinary humans. As we have discussed previously, Clarke loved the sea, and in this novella he is using what he knows in that realm to imagine a plausible ecology in the atmosphere of Jupiter. Of course when he wrote this novella no one knew about the truly frightening level of radiation around Jupiter, but then a clever science fiction writer could come up with a way to work around that. Clarke's Three Laws Finally, no discussion of Arthur C. Clarke can omit his famous Three Laws. Asimov had his Three Laws of Robotics, and Clarke had his Three Laws of Technology. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong. The only way of discovering the limits of the possible is to venture a little way past them into the impossible. Any sufficiently advanced technology is indistinguishable from magic. This concludes our look at Arthur C. Clarke, the second of the Big Three of the Golden Age of Science Fiction. And that means we are ready to tackle the Dean of Science Fiction, Robert A. Heinlein.

The Metro cars are RC cars that run off of this like 20% oil gas thing. So the oil is in the gas, it has a little motor and you can pay you know $800 for a motor or you can pay, you know, the 50 bucks for a motor. https://traxxas.com/products/models/electric/rustler-bl2s Provide feedback on this episode.

This show has been flagged as Explicit by the host. Background I have a very old EPSON R300 inkjet printer It has served me well for many years. I thought it was at least 10 if not 15 years old. I got it before I even became interested in Linux. For many of those years now I have been using this printer extensively on Linux. It has been a really good printer and has been incredibly cheap to run. Many years ago I got a number of sets of ink for it. I think they only cost me £15! A colleague at work later on gave me more sets of ink. I ended up with a large bag full of ink cartridges which I have been working my way through ever since. I used the printer infrequently for many years. This is far from ideal for an ink jet printer as doing so tends to cause the ink jet nozzles to clog up. Unsurprisingly in later years it has become somewhat temperamental. The problems consisted of paper mis-feeds (Probably down to the rubber take up rollers going hard over time) and missing bits of print (This I assume due to infrequent use of the printer and age of ink jet cartridges all of which were well out of their expiration date). The mis-fed paper could be solved by individual feeding each sheet through the printer. The poor / missing print could be solved by a combination of running the print head clean routine or by replacing the offending cartridge. Latterly I had print problems again and as per usual after cleaning the heads and then finally changing the cartridge the printer resumed printing normally. Shortly after this I bought myself an Apple iMac mini and thought it could be useful to be able to print from it. I visited the EPSON website downloaded and installed the EPSON print driver for my trusty R300 printer. I tried printing from my iMac and received a warning stating something like some of the components within your printer are worn and may need servicing. I'd never seen a message like this before as I normally print using open source print drivers on Linux which never report such things. When I tried printing on my Apple Mac no black text was visible on the page. I tried running the head cleaning routine and this made no difference. I eventually had to resort to changing the colour of the text within the LibreOffice document. This allowed me to print text that was at least legible. At the time I was a little suspicious of all this as the printer had been working so well just a few days previous. I plugged my trusty printer back into my trusty PC running an old version of Ubuntu using the open source printer drivers. Fired up LibreOffice and tried to print a document. To my surprise the printout was very good. While it was not as good as when the printer was new the quality of the black and coloured text was actually very good. My suspicion though I can't prove it is that the EPSON print driver has worked out that the printer is 10 plus years old and needs to be returned to EPSON for servicing (or to purchase a new printer). To ensure this the driver is crippling the output from the printer. The Open Source print drivers have none of the nefarious nonsense and allows the printer to operate. As I said I cannot prove any of this however I'll leave this up to you decide what you think is going on here. At this point I was going to end the podcast however the story didn't end there. The story continues My mother wanted me to print out some holiday insurance documents for her. She sent me a copy of her documents as I told her my printer was working again. The first page printed out slightly faintly but was readable the other pages seemed to print using invisible ink. I tried cleaning the heads but it made no difference. It's looking a bit like my printer or at least the cartridge is past its expiry date. Clearing out our loft I found the original box for my EPSON R300 printer and discovered that it was purchased in May 2005. This means the printer is now over 20 years old! At this point I decided that it was maybe about time that I replaced our ageing printer. We use the printer very infrequently and rarely need colour. For this reason I decided this time to buy a laser printer since I believe these don't tend to dry out like ink jet printers and are less likely to suffer with infrequent use. Only time will tell though I don't expect this one to last 20 years! Finally after all this I am not sure if using the EPSON driver had anything to do with the final demise of my printer though who knows. As Klaatu would say I leave that up to you dear listener to decide. Provide feedback on this episode.
