Linux and DOOM (1993)
  • 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.

  • The Emacs Window Management Almanac
    karthinks.com The Emacs Window Management Almanac

    Window management in Emacs gets a bad rap. Some of this is deserved, but mostly this is a consequence of combining a very flexible and granular layout system with rather coarse controls. This leaves the door open to creating and using tools for handling windows that employ and provide better metapho...

    Emacs: Denote version 2.3.0

    Information about the latest version of my Denote package for GNU Emacs.

    Emacs: Denote version 2.3.0

    > This release brings a host of user-facing refinements to an already stable base, as well as some impressive new features. There is a lot to cover, so take your time reading these notes. > > Special thanks to Jean-Philippe Gagné Guay for the numerous refinements to parts of the code base. Some of these are not directly visible to users, but are critical regardless. In the interest of brevity, I will not be covering the most technical parts here. I mention Jean-Philippe’s contributions at the outset for this reason. Though the Git commit log is there for interested parties to study things further.

    Question, How to remove all the default emacs shortcuts
  • I don't think that's a good idea. Pretty much all interaction with Emacs is mediated through keybinds. There is no distinction between shortcuts and fundamental behavior. Even ordinary typing is done by having each character on your keyboard bound to self-insert-command. Perhaps there is some way to nuke the global keymap, but then you're left with literally nothing. Besides, this would not prevent various modes from adding their own keys anyway.

    You should consider whether Emacs keybinds are actually in the way enough to be bothersome. You can also keymap-global-unset (or keymap-unset) individual bindings that you find problematic. I'd also consider delving into the Spacemacs code to see how they implement their "vi only mode."

  • Emacs 29.1.90 pretest is available

    This is the first pretest for what will become the 29.2 release of Emacs, which is primarily a bugfix release.

    TIL GNU/linux has 2 clipboards
  • 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.

  • Did we kill Linux's killer feature?
  • 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.

    Vim Wayland users: how do you bind CAPSLOCK to Escape?
  • Xremap, despite the name, supports both X and Wayland, and can be used to move modifier keys around. Configuration is done with YAML but is otherwise pretty easy. I personally use it for full Emacs keybind emulation.

  • The Phoronix forms, where AMD and NVIDIA engineers can effectively communicate

    Check out this one. It took like three posts!

  • Mastering Emacs - What's New in Emacs 29.1?
  • I have done almost the opposite: moving as much configuration as I can into use-package statements, even for built-in features like dired. You can (use-package feature-name) or even (use-package emacs) in order to customize the basics. use-package just provides much better organization than any schema that I have ever been able to come up with on my own.

    What is Hexbear and how its story intertwines to Lemmy's?
  • 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.

  • What is Hexbear and how its story intertwines to Lemmy's?
  • 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.

  • Non-Tiling Window Manager Users?
  • 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.

    New version of Devil minor mode (v. 0.5.0) available
  • I've been using Devil for a little while now. The right control key is pretty far from the home row on my keyboard, so the usual touch typing motions are inconvenient. I feel like Devil, which I have mapped to semicolon, lets me reclaim some of that.

    I have caps lock as control as well, so that gives me control access on both sides of the home row. The two sides behave a bit differently since caps lock is an actual modifier, but that hasn't been an issue for me.

  • AUR is cool... but scary
  • 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.
