    HPR4437: One Possible Definition of "Hacker"

    Play Episode Listen Later Aug 5, 2025


    This show has been flagged as Clean by the host. Hello folks of Hacker Public Radio. "A hacker is someone who invades computers". "A hacker is someone who codes". "Hacker is someone in love with technology". "Hacker is a geek, who is a person who likes nerdy things". All of those are more or less correct and of course you know someone that applies one of those popular concepts of the term. I'll defend one other, that can be as imprecise as every other, but, I feel, brings the concept closer to the general meaning of the word: "A hacker is someone in pursuit of efficiency and knowledge, be it in some specific field or maybe in anything that can be known". To be a hacker is more a characteristic of the brain than of something someone does. It's targeted to what achieve emotional, relevant responses to the person, that has to do with purpose. Everyone has a purpose, and we can see purpose as a matrix. PURPOSE: I | M | Relevant | Relevant P | purpose | purpose O | + no success | + success R | - - - - - - - - - - - - - - - - T | A | Not relevant | Not relevant N | purpose | purpose C | + no success | + success E | * * * * * * * * * * * * * * SUCCESS Where is the happy hacker located? Let's remember, a hacker is someone that seeks out meaning. The definition proposed in this show is: "A hacker is someone in pursuit of efficiency and knowledge". So, the blessed hacer is the one on the top of the matrix of purpose: it is someone that has a purpose that is relevant to him. He does not need success, he needs a reason to pursue it, even though the results are not always 100% dependent on him. If someone gives him (or her, of course) one ideia of purpose, and he adopts it as his personal search, he can achieve great success be it on any area you can imagine. But, if it is not of his heart, he will end up being less than he could be, feeling unsuccessful. Because, a hacker is not searching for efficiency on the void: he needs his brain inputted in what has relevance on this own, intimate understanding of the universe. And this is why "a hacker is someone in pursuit of knowledge and efficiency". Both together, conveying as a meaning, a meaning the hacker dedicates himself to, and that makes him happy, even in days, months or years without observable results. That need of purpose is not common to humanity. There are many many people happy in working on what comes at hand, receiving the payment, ranting about the payment and living the life Learning, pursuing purposes, lacking empathy (as hackers sometimes do), are not traits of personality of many many people. They do not try to use their brains to maximum learning, to have transcending conversations, to, eventually, teaching other people, formally or informally. Why this contrast is presented? Because a hacker is someone different, not only in the tastes and preferences. It's not a matter of what you like more, or how you prefer to do or not to do things. It's an entirely differen mind, more sensitive in some parts, more out-of-this-world in some others. Those were some points of a possible definition of hacker — that involves efficiency and knowledge as a particular composition of his thinking and feeling structure Passing through the blessings and difficulties of this particular mode of seeing the world, the universe and so on. So this is why there are computer hackers, life hackers, hackers, simply... and not everyone will end their lives knowing how to make a computer say Hello World. — Because a hacker can know and do many things — like crocheting clothes on Second Life — but not necessarily will have any interest in programming And every hacker is different. Are you one? Do you think someone can become a hacker or is this a form factor, a person comes to be without operation of the will?

    HPR4435: Philosophy, Cosmology, Physics, and just what is up with Hairy Larry's brain.

    This show has been flagged as Clean by the host. DJ Hairy Larry Presents Hairy Larry Playing Noumenology From The Archives Of Something Blue 2025-01-12 Thanks Marty, today I'm going to improvise jazz piano on a song inspired by Immanuel Kant. Now Immanuel Kant was an influential philosopher back in the 18th century and he remains influential today. Kant created a dichotomy between phenomenon and noumena where phenomenon applies to things we can perceive with the senses and noumena are things that cannot be perceived. So I wrote this song called "Noumenolgy" about the study of things that cannot be perceived. At first I thought this would be an ideal academic tenure, I mean, who could prove you wrong? But further thought led me to many scientists who deal with noumena on a daily basis. Take cosmology for instance, the study of the origins of the universe. Cosmologists have come up with the idea of the big bang, something that happened about 14 billion years ago. They check how fast the universe is expanding to come up with a number like that. And they keep building bigger and bigger telescopes because the farther away something is the longer it took for it's light to get to us which means we're really looking back into the past when we look at distant galaxies. Well, the big bang is noumenal. I mean, nobody's going to actually perceive it. So you could say that some cosmologists are, in fact, noumenologists. Or take particle physics. String theory, where we look at the stuff that makes protons and electrons, started as a mathematical exercise without proof in the real world. Definitely noumenologically inclined. But those particle physicists kept building bigger and bigger cyclotrons banging atoms together to see what escaped and they started detecting the mathematically predicted sub-particles. I read last week that they discovered a particle that has mass going in one direction and no mass going in the other. Now, how does that work? Moving on from philosophy, cosmology, and physics to noumena that actually affect ordinary people. Songwriters have written more songs about it than any other subject. Stories about it finance the publishing industry allowing them to publish books on philosophy and cosmology. And Jesus preached about it as his core message. Of course, I'm talking about love, something everyone experiences that has no phenomenal existence. You can't see it. You can't touch it. What is love? remains a valid philosophical question. So there we are. Back to Kant. On the song "Noumenology" I scat sing with a bebop and a doowop replacing actual words. So I got to thinking this morning, maybe I should write a lyric? Maybe about a cosmologist and a physicist who fall in love. Or even better a cosmologist and a physicist who bond over their shared their love for noumenology. Which brings us to the big question. Just what is up with Hairy Larry's brain and how does he come up with this stuff? I'm going to reveal my secret. Sometimes it's dreams. And sometimes, in the morning, when I'm not ready to get out of bed, you know what I mean, you've been there, my mind just goes tick tick tick and the next thing you know I've written another podcast. So now, from my "Hairy Larry Livestreams" album, here I am scat singing to "Noumenology". DJ Hairy Larry Presents Hairy Larry Playing Noumenology From The Archives Of Something Blue 2024-08-11 https://sbblues.com/2025/01/13/dj-hairy-larry-presents-hairy-larry-playing-noumenology/ Hairy Larry Livestream Something Blue Archives https://archive.org/details/hairylarrylivestreams Something Blue Archives - List Of Concerts https://archive.org/details/somethingbluearchives?sort=-publicdate music And that's Hairy Larry singing "Noumenology".

Proprietary butane adapters create refill barriers for Thermosol. 3D-printed adapters offer a customizable refill solution. Butane refill systems include nozzles tailored to Thermosol cartridges. Proprietary check valves in cartridges complicate refills. Pressure management is critical during refilling. Marking the fill line prevents overfilling. O-rings must be carefully removed to access check valves. A wood screw can extract the proprietary check valve. Refilled Thermosol devices often use Chinese-yum pads. Discolored pads indicate the need for replacement. Yard waste storage increases fire risk for Thermosol. "Slit in the middle" adapters enable effective refills. Adapter design mimics regular butane cartridge geometry. Fuel escape through slits rather than central tube. Overfilling leads to excessive pressure buildup. Reusing empty Thermosol containers via refills. Combining DIY methods with commercial refill kits. Alternative nozzles may fail without proper adapter. Proprietary valve removal enables long-term cost savings. RECOMMENDATIONS: Use 3D-printed adapters for Thermosol refills. Extract proprietary check valves with a wood screw. Mark the fill line to prevent overfilling. Replace o-rings carefully to avoid damage. Store Thermosol in fire-safe containers. Combine DIY slits with commercial nozzles. Swap out discolored pads regularly. Repurpose empty Thermosol containers via refills. Use a tapered object with a central slit for refills. Avoid proprietary adapters by modifying existing nozzles. Pressurize and depressurize during refill cycles. Source affordable Chinese-yum pads for replacements. Inspect valves for one-way check mechanisms. Follow video tutorials for adapter installation. Prioritize sealed containers for long-term storage. Adapt butane lighter attachments for Thermosol. Test refill methods with empty containers first. Document fill line marks for future reference. Compare DIY solutions to commercial refill kits. Advocate for open-standard Thermosol refills. Provide feedback on this episode.

    HPR4427: Tale of Two (Wireless) Keyboards

    This show has been flagged as Clean by the host. Hi. My name is Moss Bliss, and this is Hacker Public Radio. This is my 3rd HPR solo podcast, and you can also hear me on mintCast and Full Circle Weekly News most weeks. I watch TV via streaming on a Lenovo ThinkCentre M700 Tiny. I change streams and services using a wireless keyboard, from my recliner across the room. For a couple years, I was using a Logitech K400r, and it worked pretty well. Good keys, nice touchpad, a couple of extra features. It was kind of flimsy though, with lots of flex and keys popping off from time to time -- not so much of a problem as they popped back on well -- and then the plastic on-off slider just wore out. It had a raised strip on the plastic slider which served as something to grab with a nail, and it just eventually wore down. So I went looking for something perhaps a bit sturdier. What I found was a Rii Model K22. The box had some different numbers in addition to that, and the label on the keyboard also had other numbers, but the best way to find it is to look for the K22. It was a solid, mostly metal, keyboard, so I bought it. No flex to speak of, and the keys are made to not pop off. There are some caveats. The volume up-down and mute buttons are part of the touchpad, not physical buttons, and are not lighted. In a dark room, with a black keyboard and touchpad, it can be easy to hit the wrong area of the touchpad. Also, I have yet to get the scroll feature -- supposedly the right side of the touchpad -- to work properly, but most of the time I can scroll with two fingers on the touchpad. Also, and I have no clue why, it sometimes brings up a menu I've never seen before getting this keyboard. Yes, it's pretty easy to make it go away, but still... Unlike the K400r, the K22 has a rechargeable battery built in, and charges via USB-C. Also, the touchpad is significantly larger than that of the K400r. I have had no problems with touchpad's responsiveness, other than the issues already mentioned. I'm not really very good with touchpads, so perhaps I just haven't learned the features. I paid $18 at Walmart for the K400r, although currently on Amazon it is going for $39.89 with a cheaper model for $19.99. The cheaper model has fewer buttons and a few cutbacks on design features. The K400r has a 4.2 star rating, with 67% 5-star and 16% 4-star. The Amazon AI reports, "Customers find the keyboard functional and easy to use. They appreciate its responsive keys and convenient setup. Many find it a good value for the price, lightweight, and convenient to use from the couch. However, opinions differ on the size and touchpad responsiveness." The Logitech is wifi only, but it does come with the ubiquitous Logitech wifi dongle. The Rii K22 is currently $24.99, minus a 15% coupon as of this writing. It has a 3.9 star rating, with 56% 5-star and 15% 4-star. Amazon's AI reports, "Customers find the keyboard works well on all devices and has a responsive touchpad. They appreciate its compact size and good build quality. However, some customers have reported issues with missing keystrokes and keypad malfunctions. There are mixed opinions on the touchpad, battery life, and typing experience." The Rii keyboard can use wifi or Bluetooth easily, and comes with a wifi dongle. While I'm a touch typist, I don't use this keyboard for typing, so I can't comment on its missing keystrokes. I'm sure there are use cases where the Rii K22 would not be the best fit, but for my use, it is a huge step up from the K400r. The build quality and materials alone make it perfect for my use, where I sit in my recliner and use it to maneuver my browser and streams, and then toss it in the corner when I'm done. If you have a need for a wireless keyboard, I hope you will look at the Rii K22. But that's it for me this time. Thank you for listening, and I hope to be back soon.Provide feedback on this episode.

    HPR4417: Newest matching file

    Play Episode Listen Later Jul 8, 2025


    This show has been flagged as Explicit by the host. Overview Several years ago I wrote a Bash script to perform a task I need to perform almost every day - find the newest file in a series of files. At this point I was running a camera on a Raspberry Pi which was attached to a window and viewed my back garden. I was taking a picture every 15 minutes, giving them names containing the date and time, and storing them in a directory. It was useful to be able to display the latest picture. Since then, I have found that searching for newest files useful in many contexts: Find the image generated by my random recipe chooser, put in the clipboard and send it to the Telegram channel for my family. Generate a weather report from wttr.in and send it to Matrix. Find the screenshot I just made and put it in the clipboard. Of course, I could just use the same name when writing these various files, rather than accumulating several, but I often want to look back through such collections. If I am concerned about such files accumulating in an unwanted way I write cron scripts which run every day and delete the oldest ones. Original script The first iteration of the script was actually written as a Bash function which was loaded at login time. The function is called newest_matching_file and it takes two arguments: A file glob expression to match the file I am looking for. An optional directory to look for the file. If this is omitted, then the current directory will be used. The first version of this function was a bit awkward since it used a for loop to scan the directory, using the glob pattern to find the file. Since Bash glob pattern searches will return the search pattern when they fail, it was necessary to use the nullglob (see references) option to prevent this, turning it on before the search and off afterwards. This technique was replaced later with a pipeline using the find command. Improved Bash script The version using find is what I will explain here. function newest_matching_file { local glob_pattern=${1-} local dir=${2:-$PWD} # Argument number check if [[ $# -eq 0 || $# -gt 2 ]]; then echo 'Usage: newest_matching_file GLOB_PATTERN [DIR]' >&2 return 1 fi # Check the target directory if [[ ! -d $dir ]]; then echo "Unable to find directory $dir" >&2 return 1 fi local newest_file # shellcheck disable=SC2016 newest_file=$(find "$dir" -maxdepth 1 -name "$glob_pattern" \ -type f -printf "%T@ %p\n" | sort | sed -ne '${s/.\+ //;p}') # Use printf instead of echo in case the file name begins with '-' [[ -n $newest_file ]] && printf '%s\n' "$newest_file" return 0 } The function is in the file newest_matching_file_1.sh , and it's loaded ("sourced", or declared) like this: . newest_matching_file_1.sh The '.' is a short-hand version of the command source . I actually have two versions of this function, with the second one using a regular expression, which the find command is able to search with, but I prefer this one. Explanation The first two lines beginning with local define variables local to the function holding the arguments. The first, glob_pattern is expected to contain something like screenshot_2025-04-*.png . The second will hold the directory to be scanned, or if omitted, will be set to the current directory. Next, an if statement checks that there are the right number of arguments, aborting if not. Note that the echo command writes to STDERR (using '>&2' ), the error channel. Another if statement checks that the target directory actually exists, and aborts if not. Another local variable newest_file is defined. It's good practice not to create global variables in functions since they will "leak" into the calling environment. The variable newest_file is set to the result of a command substitution containing a pipeline: The find command searches the target directory. Using -maxdepth 1 limits the search to the chosen directory and does not descend into sub-directories. The search pattern is defined by -name "$glob_pattern" Using -type f limits the search to files The -printf "%T@ %p\n" argument returns the file's last modification time as the number of seconds since the Unix epoch '%T@' . This is a number which is larger if the file is older. This is followed, after a space, by the full path to the file ( '%p' ), and a newline. The matching file names are sorted. Because each is preceded by a numeric time value, they will be sorted in ascending order of age. Finally sed is used to return the last file in the sorted list with the program '${s/.\+ //;p}' : The use of the -n option ensures that only lines which are explicitly printed will be shown. The sed program looks for the last line (using '$' ). When found the leading numeric time is removed with ' s/.\+ //' and the result is printed (with 'p' ). The end result will either be the path to the newest file or nothing (because there was no match). The expression '[[ -n $newest_file ]]' will be true if $newest_file variable is not empty, and if that is the case, the contents of the variable will be printed on STDOUT, otherwise nothing will be printed. Note that the script returns 1 (false) if there is a failure, and 0 (true) if all is well. A null return is regarded as success. Script update While editing the audio for this show I realised that there is a flaw in the Bash function newest_matching_file . This is in the sed script used to process the output from find . The sed commands used in the script delete all characters up to a space, assuming that this is the only space in the last line. However, if the file name itself contains spaces, this will not work because regular expressions in sed are greedy . What is deleted in this case is everything up to and including the last space. I created a directory called tests and added the following files: 'File 1 with spaces.txt' 'File 2 with spaces.txt' 'File 3 with spaces.txt' I then ran the find command as follows: $ find tests -maxdepth 1 -name 'File*' -type f -printf "%T@ %p\n" | sort | sed -ne '${s/.\+ //;p}' spaces.txt I adjusted the sed call to sed -ne '${s/[^ ]\+ //;p}' . This uses the regular expression: s/[^ ]\+ // This now specifies that what it to be removed is every non-space up to and including the first space. The result is: $ find tests -maxdepth 1 -name 'File*' -type f -printf "%T@ %p\n" | sort | sed -ne '${s/[^ ]\+ //;p}' tests/File 3 with spaces.txt This change has been propagated to the copy on GitLab . Usage This function is designed to be used in commands or other scripts. For example, I have an alias defined as follows: alias copy_screenshot="xclip -selection clipboard -t image/png -i \$(newest_matching_file 'Screenshot_*.png' ~/Pictures/Screenshots/)" This uses xclip to load the latest screenshot into the clipboard, so I can paste it into a social media client for example. Perl alternative During the history of this family of scripts I wrote a Perl version. This was originally because the Bash function gave problems when run under the Bourne shell, and I was using pdmenu a lot which internally runs scripts under that shell. #!/usr/bin/env perl use v5.40; use open ':std', ':encoding(UTF-8)'; # Make all IO UTF-8 use Cwd; use File::Find::Rule; # # Script name # ( my $PROG = $0 ) =~ s|.*/||mx; # # Use a regular expression rather than a glob pattern # my $regex = shift; # # Get the directory to search, defaulting to the current one # my $dir = shift // getcwd(); # # Have to have the regular expression # die "Usage: $PROG regex [DIR]\n" unless $regex; # # Collect all the files in the target directory without recursing. Include the # path and let the caller remove it if they want. # my @files = File::Find::Rule->file() ->name(qr/$regex/) ->maxdepth(1) ->in($dir); die "Unsuccessful search\n" unless @files; # # Sort the files by ascending modification time, youngest first # @files = sort {-M($a) -M($b)} @files; # # Report the one which sorted first # say $files[0]; exit; Explanation This is fairly straightforward Perl script, run out of an executable file with a shebang line at the start indicating what is to be used to run it - perl . The preamble defines the Perl version to use, and indicates that UTF-8 (character sets like Unicode) will be acceptable for reading and writing. Two modules are required: Cwd : provides functions for determining the pathname of the current working directory. File::Find::Rule : provides tools for searching the file system (similar to the find command, but with more features). Next the variable $PROG is set to the name under which the script has been invoked. This is useful when giving a brief summary of usage. The first argument is then collected (with shift ) and placed into the variable $regex . The second argument is optional, but if omitted, is set to the current working directory. We see the use of shift again, but if this returns nothing (is undefined), the '//' operator invokes the getcwd() function to get the current working directory. If the $regex variable is not defined, then die is called to terminate the script with an error message. The search itself is invoked using File::Find::Rule and the results are added to the array @files . The multi-line call shows several methods being called in a "chain" to define the rules and invoke the search: file() : sets up a file search name(qr/$regex/) : a rule which applies a regular expression match to each file name, rejecting any that do not match maxdepth(1) : a rule which prevents the search from descending below the top level into sub-directories in($dir) : defines the directory to search (and also begins the search) If the search returns no files (the array is empty), the script ends with an error message. Otherwise the @files array is sorted. This is done by comparing modification times of the files, with the array being reordered such that the "youngest" (newest) file is sorted first. The operator checks if the value of the left operand is greater than the value of the right operand, and if yes then the condition becomes true. This operator is most useful in the Perl sort function. Finally, the newest file is reported. Usage This script can be used in almost the same way as the Bash variant. The difference is that the pattern used to match files is a Perl regular expression. I keep this script in my ~/bin directory, so it can be invoked just by typing its name. I also maintain a symlink called nmf to save typing! The above example, using the Perl version, would be: alias copy_screenshot="xclip -selection clipboard -t image/png -i \$(nmf 'Screenshot_.*\.png' ~/Pictures/Screenshots/)" In regular expressions '.*' means "any character zero or more times". The '.' in '.png' is escaped because we need an actual dot character. Conclusion The approach in both cases is fairly simple. Files matching a pattern are accumulated, in the Bash case including the modification time. The files are sorted by modification time and the one with the lowest time is the answer. The Bash version has to remove the modification time before printing. This algorithm could be written in many ways. I will probably try rewriting it in other languages in the future, to see which one I think is best.

    HPR4415: Sony WH-CH700N A2DP stops working in Fedora

    Play Episode Listen Later Jul 4, 2025


    This show has been flagged as Clean by the host. After updating the firmware on my Sony Noise Cancelling Headset, and upgrading to Fedora 40 , my A2DP ) profiles stopped working. I did a quick search and found someone with the same issue and it would be fixed in a Kernel upgrade. Common enough on a bleeding edge that is Fedora, however as the months moved on and the kernel upgraded, the problem remained. I tried to implement workarounds several times but eventually came across this passage from hank aka hankuoffroad on the Fedora Forums This is a known behavior when using Bluetooth audio on Linux on hands-free mode: you cannot use A2DP for high-quality audio output while simultaneously using the Bluetooth microphone via HSP/HFP, due to profile limitations in the Bluetooth specification and current Linux audio stack. I knew this of course, but my Sony WH-CH700N Wireless Noise Cancelling Headphones don't have a microphone. ... Hold on how does Noise Cancelling work exactly again ? Active noise control (ANC), also known as noise cancellation (NC), or active noise reduction (ANR), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first Wikipedia If the first is the background noise, it needs a microphone to capture it so it can be inverted. Ah ha...I had recently also disabled my Zoom H2v2 as it was now sometimes acting as a speaker. So presumably pipewire tries to find any microphone on the system, when it cant find the best one it will resort to the one used for noise canceling in the headset. Once the headset is been used for audio in as well, then there isn't enough bandwidth to do high definition audio, so you end up with the low quality two way profiles. Would the solution be as easy as enabling a proper microphone . . . . Provide feedback on this episode.

IDEAS Calibrating a monitor's HDR settings can significantly improve image quality by adjusting brightness and color. Using HDR (High Dynamic Range) enhances the visual experience by improving contrast and color accuracy. Adjusting black levels and brightness helps in achieving optimal visibility for both bright and dark scenes. The calibration of HDR settings involves fine-tuning various parameters like gamma, whites, and blacks. Multi-monitor setups can enhance productivity by allowing more efficient workspace organization. Curved monitors may benefit development tasks by providing a larger visual area without needing multiple displays. Managing dual monitors requires spatial awareness to efficiently switch focus between screens. Windows' snapping features help in organizing windows on multi-monitor setups, enhancing workflow efficiency. The presenter finds the transition from dual monitors to a single large curved monitor advantageous for productivity. A larger screen real estate reduces the need for physical separation of workspaces, easing multitasking. QUOTES "I will be looking at calibrating my monitor's HDR settings." "Let me know if you have any questions or suggestions in regards to these videos..." "HDR is an incredible technology that allows us to see better contrast and colors on our screens." "That way we can achieve a much more dynamic range of colors while playing games and watching media on our TVs, computer monitors, phones, etc." "It will be a bit different between calibrating a normal monitor with SDR to a HDR-enabled display." "So if the blacks are too bright then you won't really see the black levels as well." "The idea is that your brightest whites should be at 100% and your darkest blacks should be around 0%." "With this being said, I've never had a lot of luck with using my Windows HDR settings before." "A lot of people say don't buy a curved monitor for production stuff." "And now I have like basically three monitors." RECOMMENDATIONS Calibrate your monitor's HDR settings to enhance color and contrast. Adjust brightness, gamma, whites, and blacks for optimal visibility in various lighting conditions. Utilize Windows snapping features for efficient window management on multi-monitor setups. Consider transitioning to a single curved monitor for improved productivity and workspace real estate. Familiarize yourself with the tabbing system to ensure input is directed to the correct window. Experiment with panel sizes in your multi-monitor setup to find a configuration that suits your workflow. Ensure proper calibration of both SDR and HDR displays to achieve the best visual experience. Adjust black levels so they are not too bright, maintaining clear visibility of darker scenes. Set whites to 100% for better representation of bright areas in images and videos. Explore different monitor configurations to determine what enhances your productivity the most.

    This show has been flagged as Explicit by the host. Introduction On 2025-06-19 Ken Fallon did a show, number 4404 , responding to Kevie's show 4398 , which came out on 2025-06-11. Kevie was using a Bash pipeline to find the latest episode in an RSS feed, and download it. He used grep to parse the XML of the feed. Ken's response was to suggest the use of xmlstarlet to parse the XML because such a complex structured format as XML cannot reliably be parsed without a program that "understands" the intricacies of the format's structure. The same applies to other complex formats such as HTML, YAML and JSON. In his show Ken presented a Bash script which dealt with this problem and that of the ordering of episodes in the feed. He asked how others would write such a script, and thus I was motivated to produce this response to his response! Alternative script My script is a remodelling of Ken's, not a completely different solution. It contains a few alternative ways of doing what Ken did, and a reordering of the parts of his original.

He used some techniques here that I hadn't used before, and it's always great to see how other people approach the problem. Let's have a look at the script and walk through what it does, then we'll have a look at some "traps for young players" as the EEVBlog is fond of saying. Analysis of the Script wget `curl https://tuxjam.otherside.network/feed/podcast/ | grep -o 'https*://[^"]*ogg' | head -1` It chains four different commands together to "Save the latest file from a feed". Let's break it down so we can have checkpoints between each step. I often do this when writing a complex one liner - first do it as steps, and then combine it. The curl command gets https://tuxjam.otherside.network/feed/podcast/ . To do this ourselves we will call curl https://tuxjam.otherside.network/feed/podcast/ --output tuxjam.xml , as the default file name is index.html. This gives us a xml file, and we can confirm it's valid xml with the xmllint command. $ xmllint --format tuxjam.xml >/dev/null $ echo $? 0 Here the output of the command is ignored by redirecting it to /dev/null Then we check the error code the last command had. As it's 0 it completed sucessfully. Kevie then passes the output to the grep search command with the option -o and then looks for any string starting with https followed by anything then followed by two forward slashes, then -o, --only-matching Print only the matched (non-empty) parts of a matching line, with each such part on a separate output line We can do the same with. I was not aware that grep defaulted to regex, as I tend to add the --perl-regexp to explicitly add it. grep --only-matching 'https*://[^"]*ogg' tuxjam.xml http matches the characters http literally (case sensitive) s* matches the character s literally (case sensitive) Quantifier: * Between zero and unlimited times, as many times as possible, giving back as needed [greedy] : matches the character : literally / matches the character / literally / matches the character / literally [^"]* match a single character not present in the list below Quantifier: * Between zero and unlimited times, as many times as possible, giving back as needed [greedy] " a single character in the list " literally (case sensitive) ogg matches the characters ogg literally (case sensitive) When we run this ourselves we get the following $ grep --only-matching 'https*://[^"]*ogg' tuxjam.xml https://archive.org/download/tuxjam-121/tuxjam_121.ogg https://archive.org/download/tuxjam-120/TuxJam_120.ogg https://archive.org/download/tux-jam-119/TuxJam_119.ogg https://archive.org/download/tuxjam_118/tuxjam_118.ogg https://archive.org/download/tux-jam-117-uncut/TuxJam_117.ogg https://tuxjam.otherside.network/tuxjam-115-ogg https://archive.org/download/tuxjam_116/tuxjam_116.ogg https://tuxjam.otherside.network/tuxjam-115-ogg https://tuxjam.otherside.network/tuxjam-115-ogg https://tuxjam.otherside.network/tuxjam-115-ogg https://ogg http://tuxjam.otherside.network/wp-content/uploads/sites/5/2024/10/tuxjam_115_OggCamp2024.ogg https://ogg https://archive.org/download/tuxjam_114/tuxjam_114.ogg https://archive.org/download/tuxjam_113/tuxjam_113.ogg https://archive.org/download/tuxjam_112/tuxjam_112.ogg The last command returns the first line, so therefore https://archive.org/download/tuxjam-121/tuxjam_121.ogg Finally that line is used as the input to the wget command. Problems with the approach Relying on grep with structured data like xml or json can lead to problems. When we looked at the output of the command in step 2, some of the results gave https://ogg . When run the same command without the --only-matching argument we see what was matched. $ grep 'https*://[^"]*ogg' tuxjam.xml This episode may not be live as in TuxJam 115 from Oggcamp but your friendly foursome of Al, Dave (thelovebug), Kevie and Andrew (mcnalu) are very much alive to treats of Free and Open Source Software and Creative Commons tunes. https://tuxjam.otherside.network/tuxjam-115-oggcamp-2024/ https://tuxjam.otherside.network/tuxjam-115-oggcamp-2024/#respond https://tuxjam.otherside.network/tuxjam-115-oggcamp-2024/feed/ With the group meeting up together for the first time in person, it was decided that a live recording would be an appropriate venture. With the quartet squashed around a table and a group of adoring fans crowded into a room at the Pendulum Hotel in Manchester, the discussion turns to TuxJam reviews that become regularly used applications, what we enjoyed about OggCamp 2024 and for the third section the gang put their reputation on the line and allow open questions from the sea of dedicated fans. OggCamp 2024 on Saturday 12 and Sunday 13 October 2024, Manchester UK. Two of the hits are not enclosures at all, they are references in the text to OggCamp what we enjoyed about OggCamp 2024 Normally running grep will only get one entry per line, and if the xml is minimised it can miss entries on a file that comes across as one big line. I did this myself using xmllint --noblanks tuxjam.xml > tuxjam-min.xml I then edited it and replaced the new lines with spaces. I have to say that the --only-matching argument is doing a great job at pulling out the matches. That said the results were not perfect either. $ grep --only-matching 'https*://[^"]*ogg' tuxjam-min.xml https://archive.org/download/tuxjam-121/tuxjam_121.ogg https://archive.org/download/tuxjam-120/TuxJam_120.ogg https://archive.org/download/tux-jam-119/TuxJam_119.ogg https://archive.org/download/tuxjam_118/tuxjam_118.ogg https://archive.org/download/tux-jam-117-uncut/TuxJam_117.ogg https://tuxjam.otherside.network/tuxjam-115-ogg https://archive.org/download/tuxjam_116/tuxjam_116.ogg https://tuxjam.otherside.network/tuxjam-115-ogg https://tuxjam.otherside.network/?p=1029https://tuxjam.otherside.network/tuxjam-115-oggcamp-2024/#respondhttps://tuxjam.otherside.network/tuxjam-115-ogg https://ogg http://tuxjam.otherside.network/wp-content/uploads/sites/5/2024/10/tuxjam_115_OggCamp2024.ogg https://ogg https://archive.org/download/tuxjam_114/tuxjam_114.ogg https://archive.org/download/tuxjam_113/tuxjam_113.ogg https://archive.org/download/tuxjam_112/tuxjam_112.ogg You could fix it by modifying the grep arguments and add additional searches looking for enclosure . The problem with that approach is that you'll forever and a day be chasing issues when someone changes something. So the approach is officially "Grand", but it's a very likely to break if you're not babysitting it. Suggested Applications. I recommend never parsing structured documents , like xml or json with grep. You should use dedicated parsers that understands the document markup, and can intelligently address parts of it. I recommend: xml use xmlstarlet json use jq yaml use yq Of course anyone that looks at my code on the hpr gittea will know this is a case of "do what I say, not what I do." Never parse xml with grep, where the only possible exception is to see if a string is in a file in the first place. grep --max-count=1 --files-with-matches That's justified under the fact that grep is going to be faster than having to parse, and build a XML Document Object Model when you don't have to. Some Tips Always refer to examples and specification A specification is just a set of rules that tell you how the document is formatted. There is a danger in just looking at example files, and not reading the specifications. I had a situation once where a software developer raised a bug as the files didn't begin with ken-test- followed by a uuid . They were surprised when the supplied files did not follow this convention as per the examples. Suffice to say that was rejected. For us there are the rules from the RSS specification itself, but as it's a XML file there are XML Specifications . While the RSS spec is short, the XML is not, so people tend to use dedicated libraries to parse XML. Using a dedicated tool like xmlstarlet will allow us to mostly ignore the details of XML. RSS is a dialect of XML . All RSS files must conform to the XML 1.0 specification, as published on the World Wide Web Consortium (W3C) website. The first line of the tuxjam feed shows it's an XML file. The specification goes on to say "At the top level, a RSS document is a element, with a mandatory attribute called version, that specifies the version of RSS that the document conforms to. If it conforms to this specification, the version attribute must be 2.0." And sure enough then the second line show that it's a RSS file.

    This show has been flagged as Clean by the host. How does it work? qrcp binds a web server to the address of your Wi-Fi network interface on a random port and creates a handler for it. The default handler serves the content and exits the program when the transfer is complete. When used to receive files, qrcp serves an upload page and handles the transfer. The tool prints a QR code that encodes the text: http://{address}:{port}/{random_path} Most QR apps can detect URLs in decoded text and act accordingly (i.e. open the decoded URL with the default browser), so when the QR code is scanned the content will begin downloading by the mobile browser.
