  • No, it is because people in the Linux community are usually a bit more tech-savvy than average and are aware that OpenAI/Microsoft is very likely breaking the law in how they collect data for training their AI.

    We have seen that companies like OpenAI completely disregard the rights of the people who created this data that they use in their for-profit LLMs (like what they did to Scarlett Johansson), their rights to control whether the code/documentation/artwork is used in for-profit ventures, especially when stealing Creative Commons “Share Alike” licensed documentation, or GPL licensed code which can only be used if the code that reuses it is made public, which OpenAI and Microsoft does not do.

    So OpenAI has deliberately conflated LLM technology with general intelligence (AGI) in order to hype their products, and so now their possibly illegal actions are also being associated with all AI. The anger toward AI is not directed at the technology itself, it is directed at companies like OpenAI who have tried to make their shitty brand synonymous with the technology.

    And I haven’t even yet mentioned:

    • how people are getting fired by companies who are replacing them with AI
    • or how it has been used to target civilians in war zones
    • or how deep fakes are being used to scam vulnerable people.

    The technology could be used for good, especially in the Linux community, but lately there has been a surge of unethical (and sometimes outright criminal) uses of AI by some of the worlds wealthiest companies.



  • If you get the government to simply declare everyone else “terrorists” then there is no need for rule of law anymore, you can do whatever you want! Because they are by definition worse than anything we do to them. How convenient for those states with plans for committing genocide, it doesn’t count as genocide if you are mass-murdering terrorists.

    This strategy of the government calling every troublesome minority ethnic group anywhere “terrorists” got kicked into high gear when the US government started using 9/11 as an excuse to commit war crimes and remove restrictions from police forces (like the right of habeas corpus), and it has been a constant slippery slope since then. Nowadays the Biden administration officially considers the “Anti Fascist” movement in the US “terrorism,” although no one in government refers to fascist mass shooters as “terrorists.” Gee, I wonder why they would do that?





  • Emacs is a religion, or an OS

    Philosophy is a subset of religion, and there is a definitely an Emacs philosophy about making absolutely all software hackable, and controlling the computer using text.

    App platforms are a subset of operating systems. People confuse the two because most app platforms are inseparable from the operating system on which they run. But some software, like the Web, or Java, or to some extent .NET/Mono, are app platforms. Emacs is an app platform.


  • How do you think one should get started with Emacs? Should they start start with regular GNU Emacs or should they install one of the “distros”?

    I always recommend using the default setup for any software. The same goes for learning GIMP, Krita, Blender, FreeCAD, or whatever else, even though you can customize them all to your liking.

    It is usually a good idea to try and learn the workflow that was intended by the people who developed this software, you could learn something from trying to use the computer in the same way that the professionals do. Same for Emacs: professional software developers have used it for almost 50 years, the default keyboard shortcuts are set the way they are partially for random historical reasons, but partially because they often make a lot of sense.

    If you are interested, please check out my blog series on getting started with Emacs, called Emacs for Professionals

    Emacs.

    Emacs is an app platform in and of itself, and the vanilla installation comes with dozens of its own apps pre-installed. Like how web apps are all programmed in JavaScript, Emacs apps are all programmed in Lisp. All Emacs apps are scriptable and composable in Lisp. Unlike on the web, Emacs encourages you to script your apps to automate things yourself.

    Emacs apps are all text based, so they all work equally well in both the GUI and the terminal.

    Emacs comes with the following apps pre-installed:

    • a text editor for both prose and computer code
    • note taking and organizer called Org-mode (sort of like Obsidian, or Logseq)
    • a file browser and batch file renamer called Dired
    • a CLI console and terminal emulator
    • a terminal multiplexer (sort-of like “Tmux”)
    • a process manager (sort-of like “Htop”)
    • a simple HTML-only web browser
    • man-page and info page browser
    • a wrapper around the Grep and Find CLI tools
    • a wrapper around SSH called “Tramp”
    • e-mail client
    • IRC client
    • revion control system, including a Git porcelain called “Magit”
    • a “diff” tool
    • ASCII art drawing program
    • keystroke recorder and playback

    Some apps that I install into Emacs include:

    • “Mastodon.el” Mastodon client
    • “Elfeed” RSS feed reader
    • “consult” app launcher (sort-of like “Dmenu”)

  • What I do wonder about is to what extent private ownership would still be permitted to exist?

    Yeah, I think that is debatable and there are probably a few solutions, since we are only talking about hypothetical society. Just thinking out loud myself now: your example of leasing the tractor to other collectives could be done using money but there would have to be strict regulations to ensure that your lease price was fair, and maybe you would not be to charge interest, or only enough interest to cover the risk of losing the tractor. Or it could all just be done much more informally on a “to each their need” basis and the honor system, and you could maybe take them to court for a new one if they destroyed it or something.

    I wish I knew more about how it worked in countries like Vietnam or Cuba, they probably have it all worked out.


  • If I saved up my money and bought a tractor

    What if I instead offered to plow their fields for them instead

    You assume it is necessary to use money to buy a tractor for yourself, you assume “their fields” are owned by “them.” What if the state provided you with a tractor and the land? Or even if money were involved, what if the state provided you with the money to buy the tractor and the land?

    There would be laws to allow you to hire other people to use the tractor and farm the land, but by law, the surplus of their labor (whatever they planted, farm, sell at market) would belong to them, likewise the surplus of your own labor would belong to you. You could use the surplus (money, goods, what have you) to trade with anyone else.



  • I know, this one is so plausibly something those psychos in the various school board across the fucked-up state of Florida would actually do, I honestly thought this was real for a moment.

    They have already shut down entire school libraries, and censored several other public libraries, and are trying to make it illegal to speak freely about slavery or genocide or generally being critical of the US or the glorious military. And there is no shortage of 100% serious, 100% unironic talk (“protected free speech”) among ordinary Florida folk about how the slaves actually had it pretty good since they never had to worry about paying for rent or food, and anyone could have done the unskilled labor they did, “I mean, they never had human rights, but what would animals I mean black folk want with those.”

    I mean, this Onion headline is really, really plausibly real, and might even become real pretty soon.

    I have been using both professionally for at least 15 years and IMO without a doubt Qt is so much easier to use, read and work with it’s not even a comparison.

    I also use Qt professionally, and it is indeed an excellent GUI library. I have absolutely no complaints with how well it is designed and how easy it is to use, and I am consistently amazed by how beautiful the results are, especially with desktop environments like KDE Plasma.

    My complaint, which is really a deal-breaker for me, is that Qt effectively forces you into using C++ and Python and/or QML+Quick. For the non-professional software I develop, I want my apps to be scriptable by end users, and I do NOT want to force them to choose between only Python or Quick as their scripting language. For building scriptable, truly cross-platform GUI apps, Gtk is the only game in town.

    Gtk is much harder to use only if you are coding in C, because it depends so heavily on the C preprocessor to hack together the infrastructure that C++ has built-in. But because it is so easy to bind scripting languages to Gtk, you only need to program a few very core features in C, the rest you can program in any scripting language of your choice. This very important feature I think is a worthwhile trade-off for making it harder to code in C, especially if you are able to code the larger portion of your application (which is almost always the case) in a scripting language like Lua or Scheme. (Although I admit, most Gtk scripting is done in Python, just as it is with Qt.)

    Plus in comparison to Qt there are almost no commercial outfits using Gtk professionally and selling products based on it.

    Perhaps, but I would point out that both Canonical and RedHat (now IBM) are both heavily invested into developing Gnome, and I believe most of the paid Gtk development has been funded by these two companies.>

    As someone who is trying to develop my own Linux destkop apps, I can tell you that the day that I switch to Qt is the day Qt provides a feature that works as well as GObject Introspection (GI) does for Gtk. GI creates a cross-platform database of objects, properties, and signals, for auto-generating language bindings, so you can customize your Gtk programs with scripting languages (Python, Lua, Vala, JavaScript, Scheme). It is a relatively simple task to bind any programming language to GObjects thanks to GI.

    Qt does have a QMetaObject system which is similar, but C++ is a difficult language to bind to on most operating systems because of how native language functions are labeled in the library code – names are “mangled”, a hack to work around the miss-match between object libraries features (.so or .dll files), which do not provide the ability to “overload” functions, and C++ libraries features, which do provide this ability. The function/method overloading feature is used quite often in any C++ program. But decoding mangled names for language bindings can be very error-prone without the sort of automation that GI provides.

    As it is now, really the best way to develop Qt apps is to use C++, with Python for scripting, because these languages are the most well-supported by Qt (C++ natively, Python being the most stable and well-maintained “foreign” language for Qt). And I like neither of these two language. Gtk gives you a much larger selection of scripting language choices, even though it is programmed in C, and this is thanks to how well GObject Introspection works.


  • Awk is a programming language designed for reading files line by line. It finds lines by a pattern and then runs an action on that line if the pattern matches. You can easily write a 1-line program on the command line and ask Awk to run that 1-line program on a file. Here is a program to count the number of “comment” lines in a script:

    awk 'BEGIN{comment_count=0;} /^[[:space:]]*[#]/{comment_count++;} END{print(comment_count);}' file.sh
    

    It is a good way to inspect the content of files, espcially log files or CSV files. But Awk can do some fairly complex file editing operations as well, like collating multiple files. It is a complete programming language.

    Sed works similar to Awk, but it is much simplified, and designed mostly around CLI usage. The pattern language is similar to Awk, but the commands are usually just one or two letters representing actions like “print the line” or “copy the line to the in-memory buffer” or “dump the in-memory buffer to output.”


  • Whenever I open the symlink, does the software (player) understand «oh this file seems like a symlink, I should go and open the original file», or it’s a filesystem level stuff and software (player) basically has no idea if a file I’m opening is a symlink or the original movie.mp4?

    Others have answered well already, I just will say that symlinks work at the filesystem level, but the operating system is specially programmed to work with them. When a program asks the operating system to open a file at a given path, the OS will automatically “reference” the link, meaning it will detect a symlink and jump to the place where the symlink is pointing.

    A program may choose to inspect whether a file is a symlink or not. By default, when a program opens a file, it simply allows the operating system to reference the file path for it.

    But some apps that work on directories and files together (like “find”, “tar”, “zip”, or “git”) do need to worry about symlinks, and will check if a path is a symlink before deciding whether to reference it. For example, you can ask the “find” command to list only symlinks without referencing them: find -type l


  • They do! /bin has the executables, and /usr/share has everything else.

    Apps and executables are similar but separate things. An app is concept used in GUI desktop environments. They are a user-friendly front end to one or more executable in /usr/bin that is presented by the desktop environment (or app launcher) as a single thing. On Linux these apps are usually defined in a .desktop file. The apps installed by the Linux distribution’s package manager are typically in /usr/share/applications, and each one points to one of the executables in /usr/bin or /usr/libexec. You could even have two different “apps” launch a single executable, but each one using different CLI arguments to give the appearance of different apps.

    The desktop environment you use might be reconfigured to display apps from multiple sources. You might also install apps from FlatHub, Lutris, Nix, Guix, or any of several other package managers. This is analogous to how in the CLI you need to set the “PATH” environment variable. If everything is configured properly (and that is not always the case), your desktop environment will show apps from all of these sources collected in the app launcher. Sometimes you have the same app installed by multiple sources, and you might wonder “why does Gnome shell show me OpenTTD twice?”

    For end users who install apps from multiple other sources besides the default app store, there is no easy solution, no one agreed-upon algorithm to keep things easy. Windows, Mac OS, and Android all have the same problem. But I have always felt that Linux (especially Guix OS) has the best solution, which is automated package management.
