Xerolinux https://xerolinux.xyz I installed XeroLinux on an older I mac I had, mostly due to 2 factors, I had the hardware and A review I saw touted the MAC like interface from a modified KDE Plasma base. As a Plasma user, how could I resist. I had previously installed Fedora 36 on the MAC and was receiving random hardware issues at boot time, I wanted to see if the issue persisted on and Arch base, and since I had never used Arch, this was a perfect test case. The install: Power on the MAC and (if you have a MAC keyboard) press and hold the Option key. This presented me with 2 options, boot into fedora, or to the EFI partition on my USB with XeroLinux installer. Select the EFI USB device I was then presented with 4 menu options, XeroLinux installer, REFI boot options, MAC OS and reboot I chose to boot into the Installer In the GUI installer I was first given the options to install several fixes for virtual environments including Qemu and VMWare as well as an install option Next I was greeting (literally with a welcome screen proclaiming “Welcome Fellow Linux Nerds” ) I am at home...lol After selecting language, time zone and Keyboard layouts, The disk partitioning options are presented (and in much less confusing verbage than Fedora) and you are given choice of what swap partition type to use, No Swap, Swap no hibernate swap with hibernate and swap to file also a choice of file system, xfs, btrfs of ext4. I chose xfs the default, and since this is just a toy, not a high availability/high capacity server, there is no need for BTRFS, and if I am happy with the state of the system, I may well use it as a media server or Plex server and in that case I’ll need the larger file capacity of XFS Also available are the file system encryption check box and a manual partition options Under the user account setup, it detected and offered to set the machine name as MAcPro51, which is fine, it’ll help me id the device on my network, VS a unique name I would then have to come up with but would inevitably also contain “MAC” The page also included check boxes to validate password strength (forcing strong passwords, an auto-login option and an option to “reuse user password as root password. Obviously for SUDO purposes, this would not be recommended, but in my situation, I did chose it and the strong passwords validation The next screen verifies all the selections and when next is clicked, A pop-up wants you to confirm again that you want to make the changes selected. (insert jeopardy music while the install happens) During the install, there is a button to observe what is actually going on in the background, partitioning, file copies, compiles, etc First boot and login Well poop,I see a message in the boot screens referring to a hardware issue in CPU0 bank 8, there might be a hardware issue, it IS and older Intel MAC after all… Step one is, as always, update the system Picture 1 Click the thumbnail to see the full-sized image Yes, that is a silhouette of the MST3K guys, I’m using a 720 P TV as my monitor and watch movies when I’m in my home office. 121 packages are ready fro update including Kernel 5.19.12 (more jeopardy Music) next stop: install proprietary driver , open source drivers and non-preinstalled apps All this went very smoothly, as though the distro maintainers had put lots of work and thought into it. To say I’m impressed is an understatement so far. Also there’s a handy dandy “Post install system config button, let’s see what that does… Picture 2 Click the thumbnail to see the full-sized image Man, all kinds of goodies to play with!! With such goodies as Yakuake, Avanti browser and KDE connect preinstaled, the only thing I really needed was a decent office suite, Libre office, of course… The XeroLinux “Hello” app is quite a setup, offering all the tools you need to get up and running. With an app browser very similar to Discover, used by Fedora, finding LibreOffice was easy, tick a check box, a few dependencies needed confirmation, click install and poof, done. I was able to seamlessly browse the internet and watched a full length Jackie Chan movie on Netflix with no issues or buffering, Libre-office Calc opened in about 5 seconds, only marginally slower than my regular I7 desktop PC running Fedora 35. The hardware 2010 MACPRO5.1 with dual Intel Xeon 12 core processors running at 2.5Ghz and 32 GB ram and an ATI Radeon HD 5770 I bought the MAC at a local college surplus auction with no hard drive, and installed a 500GB “spinning rust” hard drive I happened to have laying around. As older hardware, it’s still fairly quiet and crash free, so far. With a modest up time of 5 days.

How to make a punch-card computer In this show we are going to make a punch-card computer out of stuff from your kitchen. Most of the materials are things you would otherwise have thrown away. What you will need An empty breakfast cereal box. Some bamboo barbecue skewers, eight for an eight bit computer, nine for a nine bit etc. These things come in cheap packs of many skewers. Or you could clean up used skewers. Scissors or a sharp craft knife. Some glue. Preferably washable PVA glue if you care about your clothes or have a small child 'helping'. Some pieces of card which you can write on, the number corresponds to the 'bit-ness' of the computer. If you used eight skewers, you need eight bits of card. These need to be slightly narrower than the cereal box. They could be made from other cereal boxes sliced up. A height of about four inches, ten centimetres is good. An enquiring mind and temporarily suspended credulity. What to do Step 1: Prepare the case of the computer. Cut off the box flaps at the top where the cereal was poured out. The computer will eventually be used standing up in the usual position with the open end at the top. Step 2: Making a chute at the bottom. You need to make a sort of chute at the bottom so that stuff that falls down into the box will slide out the front. Do this by cutting a horizontal line across the width of the box about four or five inches, about eight centimetres from the bottom edge of the box. Now cut down the front edges of the box from the horizontal slit to the bottom. This will make a flap that you can fold down by putting your hand inside and pushing it out. Hinge it down and make a fold in this flap about half an inch (one centimetre) from the front edge of the flap. Coat the inside of the flap, above the fold, with glue. Now push the flap back up and press the folded (gluey) portion of the flap against the inside of the back of the box. You could use some sticky tape to hold it down while it dries. When the glue has dried you will be able to see how this now forms a chute at the bottom of the box. Step 3: Now draw a horizontal line across the front side of the box about an inch, or 2.5 centimetres from the open end. Now is the trickiest part because you will need to do some arithmetic. Pity you don't have a computer, right? You need to measure out a number of points across this line which correspond to the bit-ness of your computer. So if you are making an eight bit computer, you need eight marks spaced equally across this line, that's nine gaps across. When you have done this you are going to pierce holes in the box with either one of the BBQ skewers or something sharper. You need for the skewers to pass right through the box and out the back side, in the same position as accurately as possible. This might be easier if you draw and measure out the same points on the back panel and push holes through from both sides. Either way what you are aiming for is to make the path through the box as accurately level and equi-distant as possible. The skewers should pass through the box and remain parallel. Step 4: We are now going to make the punched cards. Create the same number of cards as the bit-ness of your computer. So an eight bit computer will require eight cards. The cards will be almost as wide as the inside of the box, and tall enough to write stuff on but not high enough to show their bottom edges through the chute hole at the bottom of the computer. And not so tall that when they fall to the bottom they get wedged between the chute and the back wall of the computer. Laying each card flat on the table, draw a horizontal line across the card about the same distance from its top edge as you drew the line into which you punched holes in the body of the computer. You will need to measure out the same number of holes across this as the holes across your computer. Again accuracy is important if the computer is to work smoothly. Make each hole in the punched cards large enough that the skewers you used pass through the hole with no resistance. A hand-held single hole punch is good for this. The holes need to line up when the stack of cards is held flat in a pack. Step 5: Programming your punched cards. Take each card in turn and change all but one of the holes into a slot from the holes to the top of the card. For example, for card one, in an eight bit computer, leave hole zero (left-most for little-endian) as it is and for holes 1 to 7 cut from each side of the hole to the top edge, removing the little bit of card. So when a card is done it will look a bit like a comb with one hole somewhere along the row, corresponding to which bit the card represents. For the next card cut all the holes except the one to the right of the last one. When you have done this and placed the cards in a stack, you will see that what you have is a stack of cards, each of which has 1 intact hole and bit-ness minus 1 slots. Step 6: Loading the program into your computer. Holding the cards together in a stack, feed them into the top of the computer, with the punches at the top closest to the open top end of the box. Holding the cards in place so that their holes line up with the holes in the box, push skewers through from the front of the box, through the corresponding holes and slots in the stack of cards. Now when you stand the computer up, what you have is a box containing a stack of punched cards, each of which is only held in place by one skewer. And if you cut the cards to be very close to the width of the box, the cards will sit straight without drooping down at one end. Step 7: Getting some data out of your computer. Before you loaded the cards into the computer, you wrote some data on them, right? If you have an eight bit computer and you have eight kids, you will never forget their birthday again. Write the name and birthday of each child on a card and write their name above the skewer hole on the box, using the hole which corresponds to their card, the one with the intact (not a slot) in it. When you pull that skewer out, the corresponding card is no longer held in the box, and it drops down and slides out of the chute. Pity it's not quite as much fun as getting nice crisp bank notes out of a cash-machine. Finally, take a magic-marker and write 'Windows Vista' on the front of the box. And it might be a good idea to snip off the sharp ends of the bamboo skewers before you put your eye out or damage a small child. Troubleshooting Problem: When I pull out a skewer, no card drops out. Possible causes: There is too much friction between the cards or between the outer edges of the card and the sides of the box. When you load the cards, try to spread them apart a bit. And make the cards a few millimetres narrower than the box. Or the holes and slots in the cards are too small and there is too much friction between the edges of a slot and a skewer. Conclusion This is a totally pointless activity and you need to get out more. I remember seeing this somewhere when I was a very small child. Either in a book or on TV. I think it may have been my slightly older brother who made it. I have the vaguest recollection of a cereal box with some of my mum's knitting needles sticking out. If you used eight bamboo skewers, you are now the proud owner of an eight bit computer with eight bits of random access memory. A slight drawback is that each time you ask for output (pull out a skewer) the data bit you asked for is no longer inside the computer's memory. So you will have to 'reboot' every five minutes (sound familiar?). And because of the way it works, eight bits does not mean 256 different cards. But it's fun and a young kid will delight in pulling out a skewer to make a card drop out. There is glue involved as well. Mike

From Wikipedia, the free encyclopedia The Optima Batteries ChumpCar World Series is a series of automotive endurance races held on paved road race courses across North America. The races range in length from 6 to 36 hours. The name is a parody of Champ Car, a defunct open wheel professional racing series. Races are sanctioned throughout the United States, as well as in Canada and Mexico. Teams are encouraged, but not required, to decorate their cars with themes. http://www.freesound.org/ http://chumpcar.com/downloads/2014-2016chumpcar-rules.pdf http://chumpcar.com/downloads/chumpcar-rules.pdf http://chumpcar.com/register/results/89.pdf Charles please grade my math!: http://hackerpublicradio.org/eps.php?id=1353 I am using dimensional analysis. (1.97 miles X 60 seconds X 60 minutes) / (110 seconds lap time X 1 minute X 1 hour) = 64.47 MPH for one lap. now it's your turn! A slower lap took 120 seconds - how fast was Jonny going?

Public Speaking For many people, public speaking is a very traumatic thing. It is not something that has ever held any great terror for me. That is especially true now I am totally blind. My Public Speaking Rules These are some rules I live by when public speaking. These apply to things like technical talks or lectures. Not necessarily to after dinner speaking, or the speech you might give as the best man at a wedding. Those things are different entirely: NEVER start a talk with an apology for being a bad public speaker. You will be implanting in the audience the subconscious suggestion that they are about to sit through a talk given by a bumbling idiot with limited knowledge of the published subject. Three part rule. A talk about a technical or serious subject should be divided into these three parts tell them what you are going to be talking about the meat of the talk summarise what you just told them. This was given to me a very long time ago by a retired lecturer from the London School of Economics. The people in the audience wanted to be there. So there is little or no hostility in the room. And much empathy. Don't rush yourself. Pace the talk. Rushing can be a nasty feedback loop which makes your pace increase and your level of confidence plummet. Don't be afraid of pauses, or silence. These moments can give you breathing space to summarise in your own mind where you are at, whether the last thing you said needs amplification, and what is to come next. Don't be afraid of the 'ums and erms.' But keep it to a minimum. Silence is better than verbal ticks. Keep humour to a minimum. Depends on the kind of event. If you are the best man at a wedding, you are supposed to inject humour, probably at the expense of the groom. You don't need to pick out one audience member to talk to. You are just as effective if you are focused on the back wall. Talking to just one member of the audience, particularly if they are right at the front, is probably not a good look. Glancing round the room helps to make everybody feel included. Notes I probably broke some of my rules, in particular inserting verbal ticks early in the podcast. I think I improved focus as I went on. I inserted some humour, including some comments about my family Christmas, but then it is, well, Christmas. I am almost never happier than when I am learning new things. I am fiercely proud of, and amazed at the amount of things I know about a lot of subjects. I am a knowledge sponge. The one thing that does make me happier than learning, is sharing what I know. Which I often do in a tone which suggests I am just amazed at the fact I know this stuff at all. Remember, the things you don't yet know are more important than the things you already know. That is true for everybody. So share your knowledge in good spirit, keeping arrogance out of the picture.

Solar panels are not like other sources of electricity that we are used to using, such as the mains or batteries. In this episode I recount what I have learned from playing with a small few-watt solar panel and how to coax useful electricity out of it. Some multimeters were harmed in the making of this episode.

Baader-Meinhof Phenomenon This is a psychological experience. When I describe it in full, if you are of any age, you will almost certainly think "oh yes, that has happened to me." For older listeners, the name Baader-Meinhof might be memorable as a name given to a group who liked to call themselves the 'Red Army Faction.' The name Baader-Meinhof, after two notable members of the group, was given to it by journalists. In the late sixties, all through the seventies, and even into the eighties, the Red Army Faction were responsible for a number of terrorist attacks in and around East and West Germany. One person's terrorist is another person's freedom fighter, but we will not get into that discussion. This psychological phenomenon was given the name, after a man wrote a letter to a newspaper in 1994 pointing out that he had recently heard the name, Baader-Meinhof, and thereafter, seemed to hear or see it again and again. Following that, many people wrote to the same newspaper making similar comments, about recently heard names, usually nouns, which were then noticed by them frequently. The phenomenon was also given the name 'Frequency Illusion' in 2005. Wikipedia Here is the Wikipedia link to the page for the 'Frequency Illusion', also known as the 'Baader-Meinhof Phenomenon.

In today's show we will talk about installing synergy so that you can control the keyboard and mouse of another computer securely over ssh. Install synergy on both computers as root # dnf install synergy # apt install synergy The main pc is pc_middle and it is the one with the keyboard and mouse we intend to use for all the computers. The only other pc in this configuration is, one on the right which we call pc_right On pc_middle create a configuration file. I put it in ~/etc/synergy-work.conf section: screens pc_middle: pc_right: end section: links pc_middle: right = pc_right pc_right: left = pc_middle end On pc_middle add entry to ~/.ssh/config to allow portforwarding back, for the synergy port 24800 Host pc_right Hostname 192.168.0.150 RemoteForward 127.0.0.1:24800 127.0.0.1:24800 # send back from the client to me On pc_middle run synergy server in the foreground with debug enabled [user@pc_middle ~]$ synergys --debug DEBUG --no-daemon --server --address 127.0.0.1 --config ~/etc/synergy-work.conf --name pc_middle --log /tmp/synergy-work.conf.log [2022-12-03T16:29:05] DEBUG: opening configuration "~/etc/synergy-work.conf" [2022-12-03T16:29:05] DEBUG: configuration read successfully [2022-12-03T16:29:05] DEBUG: XOpenDisplay(":0") [2022-12-03T16:29:05] DEBUG: xscreensaver window: 0x00c00001 [2022-12-03T16:29:05] DEBUG: screen shape: 0,0 5760x2160 (xinerama) [2022-12-03T16:29:05] DEBUG: window is 0x05e00004 [2022-12-03T16:29:05] DEBUG: adopting new buffer [2022-12-03T16:29:05] DEBUG: opened display [2022-12-03T16:29:05] WARNING: LANGUAGE_DEBUG Poll result 0 [2022-12-03T16:29:05] DEBUG: registered hotkey ScrollLock (id=ef14 mask=0000) as id=1 [2022-12-03T16:29:05] NOTE: started server, waiting for clients [2022-12-03T16:29:05] DEBUG: event queue is ready [2022-12-03T16:29:05] DEBUG: add pending events to buffer [2022-12-03T16:29:05] DEBUG: screen "pc_middle" shape changed On pc_middle you can check that it's running [user@pc_middle ~]$ netstat -anp | grep 24800 tcp 0 0 127.0.0.1:24800 0.0.0.0:* LISTEN 90859/synergys On pc_middle you can connect to pc_right [user@pc_middle ~]$ ssh pc_right user@pc_right:~$ On pc_right (either on its own keyboard, or via ssh session from pc_middle), check that port 24800 is listening user@pc_right:~$ netstat -anp | grep 24800 tcp 0 0 127.0.0.1:24800 0.0.0.0:* LISTEN On the other keyboard that is connected to the pc_right (see note below †) user@pc_right:~$ synergyc --debug INFO --no-daemon --name pc_right 127.0.0.1 [2022-12-03T16:38:59] NOTE: started client /build/synergy-3N7yN5/synergy-1.8.8-stable+dfsg.1/src/lib/synergy/ClientApp.cpp,404 [2022-12-03T16:38:59] NOTE: connecting to '127.0.0.1': 127.0.0.1:24800 /build/synergy-3N7yN5/synergy-1.8.8-stable+dfsg.1/src/lib/client/Client.cpp,146 [2022-12-03T16:38:59] NOTE: connected to server /build/synergy-3N7yN5/synergy-1.8.8-stable+dfsg.1/src/lib/synergy/ClientApp.cpp,294 Back on pc_middle, you should see the the log that you have connected [2022-12-03T16:40:15] DEBUG: Opening new socket: 18FC73A0 [2022-12-03T16:40:15] NOTE: accepted client connection [2022-12-03T16:40:16] DEBUG: received client "pc_right" info shape=0,0 5760x2160 at 2787,1371 [2022-12-03T16:40:16] NOTE: client "pc_right" has connected † Note: If you tried to run the client synergyc over the ssh connection on pc_middle it will connect, but the mouse will never move to the other screen.

Now that everything is working correctly you can make it easier to start. As we saw before (†) the client needs to be run from the physical X Session that you see on the second computer.

Over that connection pc_right can send back commands to the server. A side note about the special address 127.0.0.1. It's often referred to as loopback, home, or localhost and is usually defined in /etc/hosts The address is used by programs running on a given computer to communicate with other programs running on the same computer. https://en.wikipedia.org/wiki/Localhost IPv4 network standards reserve the entire address block 127.0.0.0/8 (more than 16 million addresses) for loopback purposes. If you are confused, then just think of it like you when your boss says "I'm going home now, you should also go home." It's clear that they mean "I'm going to my home now, and you should also go to your home." So the address 127.0.0.1 on pc_middle is only available on pc_middle, and equally the address 127.0.0.1 on pc_right is only available on pc_right. The server is listening on its loopback address 127.0.0.1 on pc_middle, while the client is listening on its loopback address 127.0.0.1 on pc_right It is the RemoteForward configuration that creates a ssh tunnel that is doing the heavy lifting. RemoteForward 127.0.0.1:24800 127.0.0.1:24800 It tells the Remote (in this case pc_right ) to listen to the port 24800 its loopback address. This is where the client on pc_right will be talking to. The ssh connection will then Forward any packets back to the other side (in this case pc_middle ) And to send to the port 24800 its loopback address. And on that address the server is listening.

Overview I have recently been wondering about the use of abbreviations which are built from the first letter of a word followed by a number and the last letter. The number represents the count of letters between the start and end letter. Thus accessibility becomes a11y. This came to light (to me anyway) during an email exchange with Mike Ray regarding the accessibility issues on the tag index page on the HPR site. The website issues were resolved, but I was left wondering how useful the term a11y is, or whether it just jars with me! According to the Wikipedia article this type of word is known as a numeronym, but they may also be referred to as alphanumeric acronyms, alphanumeric abbreviations, or numerical contractions. As the Wikipedia article notes these types of abbreviations are almost always used to refer to their computing sense — such as g11n for globalisation — in the context of computing, not the general context. Looking at a11y as an example While I sympathise with the motivation behind using 'a11y' to mean accessibility, I do find it odd and counter-intuitive. I often find myself pondering the acceptability of this type of abbreviation. How many other words in common English fit patterns like this I wonder? Quite a few I would expect. How does this affect the admissibility of such abbreviations? Not only are they adventurously strange to my simple brain, but I find them to be aesthetically displeasing. My experiments with the standard Linux dictionary looking for words that fit this pattern I find affirmatively supportive of this view. I describe this experiment later. Algebraically, it is to be expected that there are many dictionary words of 13 characters which start with 'a' and end with 'y'. Looking at them allegorically, such numeronyms convey little meaning except in very limited contexts since the motivation seems to be to reduce the need to type long words. Alternatively, if they were accepted by data entry software and expanded automatically a better case could be made for applicability, but only one word could be assigned to a numeronym. In my mind there is a certain artificiality in the use of these abbreviations. You might wonder at the weird rambling nature of the above section - this was my (small) joke to try and use many of the words that match the a11y pattern. Here's the result of transforming them: While I sympathise with the motivation behind 'a11y' to mean accessibility, I do find it odd and counter-intuitive.

In my mind there is a certain a11y in the use of these abbreviations. Make your own numeronyms The following piece of Bash scripting scans the file /usr/share/dict/words and picks out words which match the a11y pattern (after removing those ending in 's). It writes the word and the numeronym generated from it, which it computes, though it's unnecessary in this case because they all generate the same numeronym. I did it this way because I wanted to apply the algorithm to other words: while read -r word; do printf '%-20s %s\n' "$word" "${word:0:1}$((${#word}-2))${word: -1}" done <

HPR NEWS News for the community, by the community. TAGS: Ransomware, Malware, Phishing, Security Breach Microsoft Confirms Server Misconfiguration Led to 65,000+ Companies' Data Leak Microsoft “misconfigured” an Azure Blob Storage server causing a security breach. Attackers were able to access unauthorized customer data; business transactions and other interactions between Microsoft and its customers. SOCRadar, a cyber security company, is calling the security breach “BlueBleed”. SOCRadar discovered the breach on September 24, 2022 Microsoft is downplaying the security breach but security researcher Kevin Beaumont isn't buying it. Mr. Beaumont suggest Microsoft dropped the ball on informing its customers, and federal regulators, of the security breach in a timely manner. HiddenAds malware affects 1M+ Android users McAfee’s Mobile Research Team identified multiple apps containing malware on the Google Play Store. After install, the malicious android apps automatically run services without the user knowing or interacting with the app. That’s right, they auto run after install. These malicious apps then disguise themselves by changing their icon to the “Google Play” icon and renaming to themselves to “Google Play” or “Settings”. The malicious apps quickly create permanent malicious services. McAfee’s Mobile Research Team demonstrates the resilience of the malware by using kill -9 on the service processes. More malicious processes generate immediately as if nothing happened. Fully undetectable PowerShell backdoor disguised as part of a Windows update Director of security research at SafeBreach, Tomer Bar stated, "The covert self-developed tool and the associated C2 commands seem to be the work of a sophisticated, unknown threat actor who has targeted approximately 100 victims." Based on the metadata found within a malicious document, this seems to be a LinkedIn-based spear-phishing attack, which ultimately leads to the execution of a PowerShell script via a piece of embedded macro code. "The Macro drops 'updater.vbs' creates a scheduled task pretending to be part of a Windows update, which will execute the updater.vbs script from a fake update folder under '%appdata%localMicrosoftWindows,'"said Tomar. Currently 32 security vendors and 18 anti-malware engines have flagged the decoy document and the PowerShell scripts as malicious. The findings come as Microsoft has taken steps to block Excel 4.0 (XLM or XL4) and Visual Basic for Applications (VBA) macros by default across Office apps, prompting threat actors to pivot to alternative delivery methods. Millions of patients compromised in hospital data leak. Nearly 3 million Illinois & Wisconsin patients are caught in a hospital data breach. Advocate Aurora Health, which operates 27 hospitals, said in a statement, “the breach may have exposed information including a patients' medical provider, type of appointments, medical procedures, dates and locations of scheduled appointments, and IP addresses”. The system blamed the breach on its use of pixels, computer code that collects information on how a user interacts with a website, including products developed by Google and Facebook's parent company Meta that make the collected data accessible to those companies. The health care industry's use of pixels has come under wide criticism from privacy advocates who warn that the technology's use violates federal patient privacy law. A report published in June by The Markup found many of the country's top-ranked hospitals used the Meta Pixel, collecting and sending sensitive patient information to the social media company. User space. Texas sues Google for biometric data collecting Texas has filed a lawsuit against Google claiming the tech behemoth took users’ biometric data without permission. Texas Attorney General Ken Paxton, claims Google is illegally data harvesting Texans using features and devices such as: Google Photos, Google Assistant, and Nest Hub Max. Google spokesman José Castañeda is willing to take the argument to court, “AG Paxton is once again mischaracterizing our products in another breathless lawsuit,”.

All of the URLs in these feeds use 'http' as opposed to 'https'. Although this may seem odd, this is a fairly common thing to do, because the RSS standard (such as it is) does not cater for 'https' links. There is a concern that passing an RSS feed with such links to a validator (such as the W3C Feed Validation Service) will result in it being marked as invalid.

This final episode of the DOS series continues the look at batch files by first looking at how you can use variables in writing your batch files. Then we look at how batch files can be nested, that is, how one batch file can call another batch file, thus chaining batch files together.

I found an copy of an old video. This episode is just a verbal transcription of that lecture. Electrostatic containment. Fusor. Riggatron. Multipactor. Robert Murray Smith has got some thoroughly practical and useful instructional material on Youtube. His channel is his name. He is keen to transmit knowledge and to stimulate innovation. I just looked up the books which he has written, and one of them is on the subject of this episode: Beyond The Fusor: A New Design For A Table Top Fusion Reactor And How To Build It by Robert Murray-Smith.

Introduction I have wanted an e-ink based e-reader for a while. Reading on my computer is ok. Reading on my phone is doable, but is very annoying. If I don't keep my finger on the screen, it will go blank and then I have to make sure and press the power button to bring the screen back to life before it locks. A tablet would probably be a nice compromise, but I really wanted to try out an e-ink display, and didn't want the potential distractions of a more multi-purpose device. I wanted not only and e-ink display, but also one that ran a linux operating system, and a reader that I could potentially put a different Linux distribution on, or modify myself somehow. When asked what I wanted for Christmas this year by my wonderful girlfriend, I sent her a link to the KOBO Libra H20. KOBO Libra H20 specification processor - Freescale i.MX6 SLL 1 GHz RAM - 512 MB hard drive - 8GB display - 7 inch HD 300 PPI E Ink touchscreen with 1680 x 1264 resolution dimensions - 6.3 by 5.7 by 0.3 inches (HWD) and 6.8 ounces or 159 by 144 by 7.6 mm and 192g battery - 1200 mAh. Good battery life. Currently I use it infrequently, and have charged it maybe 4 or 5 times of the last year Connectivity -WiFi 802.11 b/g/n and Micro USB. I have it connected to my home network. Have only used WiFi to update the OS. I use the USB port to transfer books I've downloaded to my computer, and to charge the Kobo. Calibre ebook management I knew about Calibre, but had never used it. So far it has been a great e-book manager. Has very nice features for editing meta data and organizing my books. It will also transfer the books to the Libra H20 and update its internal database. One thing I found is KOBO does have its own EPUB format that it uses to optimize display of books. In particular, it fixes an issue where images in standard EPUB format don't scale to the size of the page. Calibre has a plugin system, and a 3rd party plugin is available that will convert a standard EPUB format to KePUB when you transfer the book to the e-reader. Conclusion I have been enjoying my KOBO reader. It can feel a little slow at times, especially rendering pdf files where the page is a picture of the text and not made up of electronic characters, and it does render images in standard epub format a bit small at times. Other than these two things, it is very easy to read in all lighting settings, and I enjoy reading using the KOBO.

Inetd, the internet super-server Inetd is slowly becoming one of my favorite daemons. It makes writing programs that talk over the network super easy. Inetd handles all of the hard socket stuff and allows admins to write simple UNIX-ey programs. Inetd is useful because it allows us to write services that only run when they are requested in order to reduce total system load. How inetd works Inetd can be conceptualized as a sort of "wrapper daemon". Inetd is always running despite the fact that many of it's sub-services are not always running. Inetd listens on a specific port. When it gets a request, it handles all of the hard socket parts. This request is then passed to one of our inetd services We will use a simple server that echoes the request back to the user as an example. We will call this inetd service echod Inetd passes requests to echod as text. echod will read from stdin and write to stdout. Everything written to stdout is passed to the client. echod will then exit. echo server example I use OpenBSD on my webserver. Sadly, systemd sockets have replaced inetd on many linux systems. systemd sockets are entirely painful to use. I can't verify that these examples will work on non-OpenBSD systems but the openbsd-inetd package is available on a wide variety of debianoiads. Let's write out out echod service and the configuration files required to get it working. Edit /etc/inetd.conf # port socket type protocol wait/nowait user server program server arguments(optional) 9999 stream tcp nowait daemon /opt/echod/echod.sh And our echod service file, located at /opt/echod/echod.sh: #!/bin/sh while read l; do echo $l; done; exit 0; Be sure to chmod +x echod.sh and rcctl enable inetd && rcctl start inetd or it won't run. Testing Sometimes you can use curl to test a service but I will use netcat instead because it doesn't assume http. $ echo "foobar" | nc -N localhost 9999 foobar $ You can also use telnet to test the service: $ telnet localhost 9999 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. foo foo foobar foobar echo back echo back ^] telnet> Connection closed. $ Finger server example Many months ago, I wrote a finger server to learn more about how inetd works (and to write a finger daemon that doesn't allow for enumerating non-regular users). You can download the source code for my finger server from my gitlab. This finger server only allows information from users who have a home directory in /home/ to be displayed. It also has hard-coded filenames it looks for. Example output looks something like: $ finger binrc@localhost [localhost/127.0.0.1] binrc@openbsd.my.domain https://0x19.org Working on an HPR episode binrc.nospam@nospam.protonmail.com No .pgpkey $ Gopher server example Currently, I am working on a gopher server that runs through inetd to learn more about how gopher works (and to write a gopher server that doesn't allow for path traversal). I have yet to add autoindex support but I thought it would be good to include anyway because it really demonstrates how simple it can be to write an inetd service. You can download the source code for my gopher server from my gitlab. This gopher server reads input from standard in and prints the requested file to standard out. Writing an inetd service can be as easy as writing an application specific version of cat(1). Giving the service SSL You can pair inetd with relayd to make any inetd service use ssl. In this example, I am symlinking my existing httpd certs obtained with acme.sh # ln -s /etc/ssl/example.com.fullchain.pem /etc/ssl/example.com:9998.crt # ln -s /etc/ssl/private/example.com.key /etc/ssl/private/example.com:9998.key A sample relayd configuration looks like: log connection tcp protocol "echod" { tls keypair "example.com:9998" } relay "echod" { listen on example.com port 9998 tls protocol "echod" forward to 127.0.0.1 port 9999 } After enabling and starting relayd, it will now be listening on port 9998. When it receives traffic on 9998, it will perform all of the fancy cryptography stuff and pass the request to localhost:9999. Since relayd is listening on 9999 and passing requests on 9999 to the echo server, we are now running an echo server with ssl. Conclusion Do I run inetd in production? No, not really. I have in the past but I haven't needed it seeing as finger, echo, and gopher are dead protocols. Even if inetd is largely useless in the modern era, it's still fun to play with.

Smite, the battleground of the GODS. SMITE is a free-to-play online MOBA (Multiplayer Online Battle Arena) and ARTS (action real-time strategy) game developed by Titan Forge Games and published by Hi-Rez Studios. The game is currently available on PC, Xbox One, PlayStation 4 and Nintendo Switch. Players choose from a large selection of playable gods, immortals, and creatures from ancient mythology and join session-based arena combat. Each of the playable characters have their own unique abilities and fighting styles. This session-based arena combat is mostly 5 players against another set of 5 players, but there are several other Game Modes with different rules and objectives, and the goal in most of them is to defeat the Titan located in the opposite team's base while protecting your own Titan.

Recently I returned to Kdenlive after about a 10-year break, and was pleased to discover the speech recognition feature. https://docs.kdenlive.org/en/effects_and_compositions/speech_to_text.html#install-python

We get to our first major stop for a week in Topock, Arizona. From here we can check out places like Oatman, Arizona and Lake Havasu, Arizona. We make a few more mistakes, but learn from them. Links: https://www.palain.com/travel/into-arizona/

Why the PBP? Lately I've been thinking a lot about power consumption when it comes to computing. Intuitively, I know that arm devices pull significantly less power than amd64 machines but I've never really tested this in the real world. So, some preliminary power consumption stats: big amd64 laptops (thinkpad x220 and t490) pull at most 65 watts small arm SOCs typically pull at most 15 watts most android phones pull at most 18 watts Pentium 4 pulls at most 250 watts These numbers are fairly easy to find: just look at the power supply for a MAXIMUM OUTPUT value or something similar. This is the point at which the power supply fails so we can safely assume this is the maximum power draw for any given computer. Of course, this is DC output and not AC output and anyone who knows anything about electricity knows that converting AC to DC is expensive but these values are useful as a general estimate. I wrote something similar about computer power consumption some time ago My goal in all of this was to find a self contained computer that runs UNIX, doesn't take much power, isn't a consumption rectangle (smartphone), and can be charged from both AC with a rectifier and stored DC without an inverter. Charging from existing stored power was probably the most novel consideration. Everything else is a given. A few obvious answers come to mind: Raspberry Pi 4 is not self contained and using a pitop in public is a good way to get the bomb squad called on you beaglebone black is good too but neither self contained nor popular enough for wide OS support Pinebook Pro is self contained and is supported by some of the operating systems I'd like to run The PBP is an obvious choice. It's an open hardware ARM laptop that can be charged via a barrel cable (AC->DC) or via USB-C. Charging from USB-C is a very useful feature because it means I can easily choose between charging from the mains where efficiency loss is acceptable and charging from a DC source where efficiency loss is unacceptable. The actual use case is "what computer can I run off of a old car battery or the alternator in my car without burning power with an inverter?". I'll revisit this use case in a later section. Initial notes I took these notes immediately upon opening the PBP. They remain unedited because I want to be honest on the first impressions. shipping I was worried about DHL dropping my package out of a plane. Or leaving it out in the rain. Or having one of the employees use it as a soccer ball. Or having the thing get stuck in customs. It ended up arriving safely and was packaged well. Two boxes within a padded envelope within another envelope. Surprising for DHL. hardware impressions Touchpad sucks and trackpad scrolling sucks (it's probably just KDE). Installing synaptics drivers allegedly fix this problem. keyboard is comfortable, clickly, full sized despite being a chicklet keyboard. I don't like that the and keys are backwards when compared to a thinkpad. I really like the thinkpad keyboard layout. Shift+enter seems to type the M character. My muscle memory for key chording is now broken. This appears to be a fundamental design flaw with KDE. Passively cooled, gets a bit warm. display is sharp (IPS) and almost too high resolution for my eyes (1920x1080 instead of 1366x768). I can fix this in software. enabling/disabling mic/wifi/camera through the keyboard is confusing and (seemingly) does not perform the "kill switch" via hotplugging like the Thinkpad X220's wifi kill switch. Charger comes with both US and EU prongs. software impressions it's manjaro :( it's KDE :( it comes with mpv :) bluez instead of bluetoothd :( firewalld instead of UFW WiFi dongle. To get around no RJ45 port, I use a USB->RJ45 adapter. I have an ASIX ax88772 dongle (UGREEN branded but I'm not sure that matters). Both of these dongles seem to work with every single operating system and hardware configuration I've tried them with. Arm is strange, so we must boot from an SD card (running any OS, in my case NetBSD) in order to burn an image to the internal storage. From a separate machine, the options passed to dd are important. $ wget https://cdn.netbsd.org/pub/NetBSD/NetBSD-9.3/evbarm-aarch64/binary/gzimg/arm64.img.gz $ wget http://cdn.netbsd.org/pub/pkgsrc/packages/NetBSD/x86_64/.9.0_2022Q2_pkgbuild/All/u-boot-pinebook-pro-2022.01nb1.tgz $ gunzip ./arm64.img $ tar xzf ./u-boot-pinebook-pro-2022.01nb1.tgz $ sudo umount /dev/sdx* $ sudo dd if=./arm64.img of=/dev/sdx status=progress conv=fsync bs=1M $ sudo sync $ sudo dd if=./u-boot-pinebook-pro-2022.01nb1/share/u-boot/pinebook-pro/rksd_loader.img of=/dev/sdx seek=64 conv=sync status=progress $ sudo sync $ sudo eject /dev/sdx And, to install NetBSD to the internal EMMC, the process is similar. NetBSD's version of dd varies slightly but the options passed are important. # ftp https://cdn.netbsd.org/pub/NetBSD/NetBSD-9.3/evbarm-aarch64/binary/gzimg/arm64.img.gz # gunzip ./arm64.img # dd if=./arm64.img of=/dev/rl0d conv=sync bs=1m # sync # PKG_PATH="http://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/aarch64/9.3/All/" pkg_add pkgin # pkgin install u-boot-pinebook-pro # sudo dd if=/usr/pkg/share/u-boot/pinebook-pro/rksd_loader.img of=/dev/rld0 seek=64 conv=sync # sync # reboot And, some more desktop centric things after booting from EMMC: # passwd # echo "postfix=NO" >> /etc/rc.conf # echo "xdm=YES" >> /etc/rc.conf Installing pkgin (and some packages): # PKG_PATH="https://cdn.NetBSD.org/pub/pkgsrc/packages/NetBSD/aarch64/9.3/All/" pkg_add pkgin # sed -i'' -e 's/9.0/9.3/g' /usr/pkg/etc/pkgin/repositories.conf # pkgin install vim git mozilla-rootcerts mozilla-rootcerts-openssl The rest is NetBSD specific and I've avoided getting into it here because it doesn't have anything to do with the PBP. Performance The PBP has 6 cores (2 fast, 4 slow) and 4gb ram. The cpu is fairly slow but entirely usable. On large procedural jobs like software compilation, it's painful. For concurrent jobs, it's mostly fine. Compiler performance As expected, the PBP is slower when it comes to compilation than a standard amd64 machine. Surprisingly enough, NetBSD was significantly slower than Manjaro. This is likely due to the Linux kernel knowing how to better handle multiple CPUs with varying speeds. sequential jobs I used plan9port because it's a fairly large but portable project. Compilation is largely sequential, invokes many standard shell utilities, and involves extra preprocessor steps to convert 9 C into something a standard UNIX compiler like GCC or Clang can compile.

I found a few web browser benchmark tests at browserbench.org. They're probably snakeoil but running JS tests is a good way to put a number on how performant $browser on $hardware is. Scores from the JetStream2 test JetStream 2.1 is a JavaScript and WebAssembly benchmark suite focused on the most advanced web applications. It rewards browsers that start up quickly, execute code quickly, and run smoothly. For more information, read the in-depth analysis. Bigger scores are better. Thinkpad T490 79.555 Thinkpad X220 39.983 PBP (manjaro) 19.148 I don't have an chromesumption book to test against, so all I can say is that the PBP is slower than a workhorse amd64 machine when it comes to interpreting javascript. Conclusion Did the PBP fulfill it's needs? The intended use case was "UNIX machine I can charge from an existing battery or alternator". This immediately invokes ideas of "why would I even need wifi support?" Ultimately, I ended up flashing a bad image to the SPI flash chip and I cannot get the system to boot (or even show signs of life). I have attempted to enter maskrom mode to re-flash the SPI but I am unsuccessful. There are a few other things I need to try. I'll update this if I ever get it functional again. I did not have the opportunity to test the machine in the exact environment I got it for but it was fun before I bricked it. Again, a place for updates. Who is the PBP for? HACKERS! Obviously, the types of people who are interested in pine64 devices and similar SBCs are already computer owners (if not computer hoarders). It's unlikely that the PBP will become my (or anyone's) primary computer but that doesn't mean that it's useless. The entire point of arm SBCs is to have fun so why not have fun? Just don't flash your SPI if you want it to work as expected. Some final thoughts on open hardware Oftentimes, before purchasing freedom centric hardware, I search for a few reviews so that I can set my expectations correctly. Oftentimes these reviews are very epidermal: they're not even skin deep. These reviewers are consumers producing reviews for a consumer audience, not hackers producing in-depth reviews for hacker audience. These types of reviews are frustrating for me but fundamental flaws seem to shine through the lack of thoroughness. I think that the general negative reviews on open hardware largely stem from unrealistic expectations. The community seems to over-hype many of these devices out of ignorance, stating that $freedomDevice is the $proprietaryAlternative killer, the end all be all device that will usher in the year of the Linux $deviceCategory. Oftentimes, it seems like the high expectations fall flat when confronted with the reality of open hardware: it's either way too expensive or way too experimental. It seems like many of these devices are lacking both developer time and users who are both enthusiastic and knowledgeable. Pitfalls of mobile UNIX include bad power management, difficulty hotplugging wireless chipsets, graphical interfaces attempting to cope with the fact that they don't have a physical keyboard, etc. There is still much work to be done. As for users, it seems that the most enthusiastic users always have the impression that $linuxDevice will have 1:1 feature parity with $proprietaryDevice. Maybe it's just that the loudest users are heard or that we only want to hear utopian dreams of a free software future. A prime example of this conflict between expectations and reality: Linux smartphones. It doesn't help when many linux smartphones over the years were advertised as a viable android competitor rather than anything other than what they actually were: an arm board attached to a touch screen and a modem. I oftentimes ask myself "what is open source worth?". How much money are you willing to throw at an idea you like? Surely, money thrown at an idea you like is being used better than money thrown at an idea you don't like. In many cases, it seems like open hardware devices are more expensive than their proprietary counterparts for a few reasons. The two largest reasons are small batch manufacturing and the fact that open hardware isn't subsidized by pre-installed adware (in the case of nearly every device that comes pre-loaded with proprietary software). What is open source worth? A few extra dollars, a few extra hours of configuration, a few extra papercuts, and a clean conscious knowing that I didn't pay for yet another windows license I will never use and will never get a refund for. Open source is worth investing in because the, albeit slow, improvements to open hardware and software have wider implications than just "buying a laptop with Linux pre installed". Future projects something with the raspi NetBSD in depth "why is my lightbulb running android?" and other Internet-Of-Terror ideas turning a router into a general purpose computing device (probably MIPS because where else am I going to find a MIPS CPU? Might as well do something novel instead of $arm-project-1209)

Synopis I installed a new 1TB Crucial MX500 SSD into my work computer. While we are mostly a Windows based business, as the IT guy I do get a bit of discretion when updating my own machine (i.e. I get to solve all the problems I create). Last year, I decided to run the Pop!_OS distribution of Linux on my work computer and run Windows in a VM on it. Recently the Windows image had grown and was causing disk space notifications. This prompted the additional hard drive. During the initial installation of Pop!_OS, I remember deciding not to bother with installing Linux Volume Management (LVM). I have used it in the past, but I am still much more comfortable with the old style device mapping and mounting disk partitions to directories. I even rationalized that if I needed to add more space, I will just add a new disk with one big partition and map it to the home directory. Now a year later I am adding a new HD and thinking, I really hate all the space that is most likely going to be wasted once I move the Windows image to the new drive. Ok, I guess I should figure out how to install LVM, and use it to manage the space on both drives. Luckily there a number of good blogs to be found on adding LVM to an existing system. The following are the steps and commands I used to accomplish my goal. Commands Most of the following commands need to be run as root. I decided to change to root user instead of typing sudo before every command. The basic steps to creating a single filesystem sharing the storage space between two physical disk partitions are: Let LVM know about the new disk. In my case, create a volume group and add the new disk and its full storage space to it. Copy the disk partition with the root filesystem from the origin disk to the new volume group Expand the root filesystem on the volume group to the full size of the volume group. Update system configuration to boot with the root filesystem on the new volume group. Let LVM know about the old root disk partition. Add the old root partition to the volume group. Expand the root filesystem on the volume group to include the new space in the volume group. root@work# pvcreate /dev/sdb root@work# pvdisplay "/dev/sdb" is a new physical volume of "931.51 GiB" --- NEW Physical volume --- PV Name /dev/sdb VG Name PV Size 931.51 GiB Allocatable NO PE Size 0 Total PE 0 Free PE 0 Allocated PE 0 PV UUID wRBz38-xxxx-xxxx-xxxx-xxxx-xxxx-xxxxxx root@work# vgcreate workvg /dev/dsb No device found for /dev/dsb. root@work# vgcreate workvg /dev/sdb Volume group "workvg" successfully created root@work# vgdisplay --- Volume group --- VG Name workvg System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 1 VG Access read/write VG Status resizable MAX LV 0 Cur LV 0 Open LV 0 Max PV 0 Cur PV 1 Act PV 1 VG Size 931.51 GiB PE Size 4.00 MiB Total PE 238467 Alloc PE / Size 0 / 0 Free PE / Size 238467 / 931.51 GiB VG UUID 67DSwP-xxxx-xxxx-xxxx-xxxx-xxxx-xxxxxx root@work# pvdisplay --- Physical volume --- PV Name /dev/sdb VG Name workvg PV Size 931.51 GiB / not usable 1.71 MiB Allocatable yes PE Size 4.00 MiB Total PE 238467 Free PE 238467 Allocated PE 0 PV UUID wRBz38-xxxx-xxxx-xxxx-xxxx-xxxx-xxxxxx root@work# lvcreate -n root -L 931.51 workvg Rounding up size to full physical extent 932.00 MiB Logical volume "root" created. root@work# cat /dev/sda3 >/dev/mapper/workvg-root cat: write error: No space left on device Hmmm why can't it copy the smaller disk onto a larger one? root@work# pvdisplay --- Physical volume --- PV Name /dev/sdb VG Name workvg PV Size 931.51 GiB / not usable 1.71 MiB Allocatable yes PE Size 4.00 MiB Total PE 238467 Free PE 238234 Allocated PE 233 PV UUID wRBz38-xxxx-xxxx-xxxx-xxxx-xxxx-xxxxxx root@work# lvdisplay --- Logical volume --- LV Path /dev/workvg/root LV Name root VG Name workvg LV UUID srXpUd-xxxx-xxxx-xxxx-xxxx-xxxx-xxxxxx LV Write Access read/write LV Creation host, time work.example.com, 2022-10-18 08:46:34 -0400 LV Status available # open 0 LV Size 932.00 MiB Current LE 233 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:1 Whoops, the default unit for the lvcreate is MB, and I forgot to add G to my size.

HPR News. Threat Analysis; your attack surface. Wireless key fobs compromised in European nations (France, Spain, and Latvia). On October 10, 2022, European authorities arrested 31 suspects across three nations. The suspects are believed to be related to a cybercrime ring that allegedly advertised an “automotive diagnostic solution” online and sent out fraudulent packages to their victims. The fraudulent packages contained malware and once installed onto the victims vehicle, the attackers were able to unlock the vehicle, start the ignition, then steal the vehicle without the physical key fob. European authorities confiscated over €1 million in criminal assets (malicious software, tools, and an online domain). Microsoft Office 365 has a broken encryption algorithm. Microsoft Office 365 uses an encryption algorithm called “Office 365 Message Encryption” to send and receive encrypted email messages. The messages are encrypted in an Electronic Codebook (ECB). The U.S. National Institute of Standards and Technology (NIST) reported, "ECB mode encrypts plaintext blocks independently, without randomization; therefore, the inspection of any two ciphertext blocks reveals whether or not the corresponding plaintext blocks are equal". Emails can be harvested today then decrypted later for future attacks. User Space. Netflix crackdown on freeloaders. Netflix is testing in Argentina, the Dominican Republic, El Salvador, Guatemala, and Honduras Chile, Costa Rica and Peru different efforts to crackdown on freeloaders.
