    The reason that Doom is so portable goes beyond Linux and is an artefact of its development. id developed Doom on NeXTSTEP (i.e. Unix) machines and obviously targeted DOS. This is pretty unique among DOS games at the time and required id to write as much code as possible in a platform agnostic way. This means that the main engine does not care about where it is running and the usual DOS hacks are contained to DOS-specific files. In order to port Doom to a new platform, ideally one only needs to rewrite the system-specific implementation files for video, sound, filesystem access, etc., and this mostly holds true today. (These files are prefixed with i_ in the Doom source).

    The Linux port is just one of many versions developed at the time. I don’t believe that it was commercially released; it was more of a portability test. The reason that the Linux version was chosen for the source release over the DOS version was because it didn’t rely on the proprietary DMX sound library that the DOS port used.


  • Emacs’s regular clipboard is the “kill ring” which also allows you to retrieve any previously cut/copied text. It also has “registers” where you can store and retrieve snippets of text, which can be considered clipboards when used for this purpose. Registers can be referenced by any character you can type on your keyboard, including control characters like ^D.

    This totals… a lot of clipboards.

    I think that this is above all else the reason that I use Arch. Arch Linux makes creating packages trivial, basically just wrapping build instructions into a shell script template. Arch handles the rest. The build systems for deb or rpm packages don’t come close, and good luck rolling your own flatpak.

    This allows me to use pacman for everything outside of my home directory. Pacman is practically the central feature of my computer, and it’s wonderful. I’m sure those Nix people can relate, though I guess my method is a bit less robust.



  • r/cth was originally a subreddit for the podcast Chapo Trap House, but it eventually bloomed into a general-purpose leftist space. IIRC, the sub was around 160k members at its peak and had a distinct posting culture.

    It was quarantined by Reddit for violent speech after calling for the death of slave owners and later banned for no particular reason at the same time as r/the_donald, presumably as a “both sides” sort of thing.


  • Hexbear is an instance formed mostly by former r/chapotraphouse users after that sub was banned from Reddit a few years ago. Hexbear used to run on a custom fork of Lemmy so that the community could add extra features that they wanted (like custom emoji) but it was recently ported back to mainline Lemmy after merging or reimplementing as many changes as possible.

    Currently, Hexbear does not have federation enabled, and there is discussion about who to federate with or even whether to federate at all. The community is very active and self-sufficient and some members prefer the isolation.

    Content-wise, it’s a leftist-focused instance. Some shitposts, some serious posts, and a lot of inside jokes.

    I am a proud Openbox user. In the stacking realm, there is nothing quite like Openbox’s customizeability and the great tooling that surrounds it. In particular, opensnap gives me window snapping to the edge of the screen with the mouse, which is sorely missing from most light window managers. Openbox also has really powerful hotkeys (any arbitrary sequence of actions) alongside Emacs-style key chords, which makes it difficult to port my setup to any other environment.

    One day, I hope to migrate to labwc, which seems to be carrying Openbox’s banner into the Wayland era. Unfortunately, labwc doesn’t (and probably never will) support key chords and I have not been able to find a suitable replacement for tint2, which I use as my taskbar. Someday…

    Here is an old screenshot of mine. Nothing has changed since then.




  • I use Elfeed for Emacs, as just one small part of Emacs’s slow conquest of other programs on my computer. Before that, I used Liferea, which is a nice standalone feed reader.

    Elfeed lets me assign each feed in my list different tags, so I can do basic filtering for what I want to read at any given time. I generally avoid subscribing to any high-density feeds like news sites. I prefer to have maybe a dozen or so links per day that definitely interest me.

    I use morss.it to fetch the full text from feeds that only provide a brief summary.


  • This is the main reason that one should learn to read PKGBUILDs. Any AUR helper like Yay or Paru should give the option. Just make sure that the package downloads from an official source and contains only the necessary build and install instructions.

    But I agree. Some people treat the AUR as just another repository, when it most definitely is not.
