There’s always something more urgent: I’ve been known for a long time that sooner or later I’d feel prompted to switch from #github to somewhere else (since 2018 at least!), but I’ve been postponing and only very slowly flirting with the idea… That didn’t work too bad for me: if I had rushed into it I would have probably migrated to #gitlab, before knowing about the more objectionable sides to it. In the end, 2025 was the year I finally acted upon the urge to move. I did not do a very thorough analysis of the alternative hosts - what I have been reading about them along the years felt enough, and I easily decided to choose #codeberg. Being hasty like that, alas, was a mistake: I just now found - during this slow and time-consuming process of deciding what and how to migrate - that there is a low repository limit on codeberg: “The owner has already reached the limit of 100 repositories.” I’m not complaining, mind you, and those “lucky 100” that are already there will stay - at least as a sort of backup. But this means that codeberg is not for me - and so this time I turn to you, the #mastodon community.

What github alternative, not self-hosted, should I move my >100 projects into?

I’ve got a prototype of my hardcopy simulator going. I’m typing on the keyboard and the “display” goes to the printer:

https://movq.de/v/56feb53912/s.png

https://movq.de/v/235c1eabac/MVI_8810.MOV.mp4

The biiiiiiiiiig problem is that the print head and plastic cover make it impossible to see what’s currently being printed, because this is not a typewriter. This means: In order to see what I just entered, I have to feed the paper back and forth and back and forth … it’s not ideal.

I got that idea of moving back/forth from Drew DeVault, who – as it turned out – did something similar a few years back. (I tried hard to read as little as possible of his blog post, because figuring things out myself is more fun. But that could mean I missed a great idea here or there.)

But hey, at least this is running on my Pentium 133 on SuSE Linux 6.4, printer connected with a parallel cable. 😍

And GNOME used to have them, too: https://upload.wikimedia.org/wikipedia/commons/9/9f/Gnome-2-22_%284%29.png

I like the looks of your window manager. That’s using Wayland, right? The only thing on this screenshot to critique is all that wasted space of the windows not making use of the full screen!!!1 At least the file browser. 8-)

This drives me nuts when my workmates share their screens. I really don’t get it how people can work like that. You can’t even read the whole line in the IDE or log viewer with all the expanded side bars. And then there’s 200 pixels on the left and another 300 pixels on the right where the desktop wallpaper shows. Gnaa! There’s the other extreme end when somebody shares their ultra wide screen and I just have a “regularish” 16:10 monitor and don’t see shit, because it’s resized way too tiny to fit my width. Good times. :-D

Sorry for going off on a tangent here. :-) Back to your WM: It has the right mix of being subtle and still similar to motif. Probably close to the older Windowses.

@prologic@twtxt.net Yeah, it’s not a strong sandbox in jenny’s case, it could still read my SSH private key (in case of an exploit of some sort). But I still like it.

I think my main takeaway is this: Knowing that technologies like Landlock/pledge/unveil exist and knowing that they are very easy to use, will probably nudge me into writing software differently in the future.

jenny was never meant to be sandboxed, so it can’t make great use of it. Future software might be different.

In-reply-to » PSA: setpriv on Linux supports Landlock.

Another example:

$ setpriv \
    --landlock-access fs \
    --landlock-rule path-beneath:execute,read-file:/bin/ls-static \
    --landlock-rule path-beneath:read-dir:/tmp \
    /bin/ls-static /tmp/tmp/xorg.atom

The first argument --landlock-access fs says that nothing is allowed.

--landlock-rule path-beneath:execute,read-file:/bin/ls-static says that reading and executing that file is allowed. It’s a statically linked ls program (not GNU ls).

--landlock-rule path-beneath:read-dir:/tmp says that reading the /tmp directory and everything below it is allowed.

The output of the ls-static program is this line:

─rw─r──r────x 3000 200 07-12 09:19 22'491 │ /tmp/tmp/xorg.atom

It was able to read the directory, see the file, do stat() on it and everything, the little x indicates that getting xattrs also worked.

3000 and 200 are user name and group name – they are shown as numeric, because the program does not have access to /etc/passwd and /etc/group.

Adding --landlock-rule path-beneath:read-file:/etc/passwd, for example, allows resolving users and yields this:

─rw─r──r────x cathy 200 07-12 09:19 22'491 │ /tmp/tmp/xorg.atom

In-reply-to » The lack of suckless-like simple, hackable software these days is appalling.

@prologic@twtxt.net Yeah, this really could use a proper definition or a “manifest”. 😅 Many of these ideas are not very wide spread. And I haven’t come across similar projects in all these years.

Let’s take the farbfeld image format as an example again. I think this captures the “spirit” quite well, because this isn’t even about code.

This is the entire farbfeld spec:

farbfeld is a lossless image format which is easy to parse, pipe and compress. It has the following format:

╔════════╤═════════════════════════════════════════════════════════╗
║ Bytes  │ Description                                             ║
╠════════╪═════════════════════════════════════════════════════════╣
║ 8      │ "farbfeld" magic value                                  ║
╟────────┼─────────────────────────────────────────────────────────╢
║ 4      │ 32-Bit BE unsigned integer (width)                      ║
╟────────┼─────────────────────────────────────────────────────────╢
║ 4      │ 32-Bit BE unsigned integer (height)                     ║
╟────────┼─────────────────────────────────────────────────────────╢
║ [2222] │ 4x16-Bit BE unsigned integers [RGBA] / pixel, row-major ║
╚════════╧═════════════════════════════════════════════════════════╝

The RGB-data should be sRGB for best interoperability and not alpha-premultiplied.

(Now, I don’t know if your screen reader can work with this. Let me know if it doesn’t.)

I think these are some of the properties worth mentioning:

  • The spec is extremely short. You can read this in under a minute and fully understand it. That alone is gold.
  • There are no “knobs”: It’s just a single version, it’s not like there’s also an 8-bit color depth version and one for 16-bit and one for extra large images and one that supports layers and so on. This makes it much easier to implement a fully compliant program.
  • Despite being so simple, it’s useful. I’ve used it in various programs, like my window manager, my status bars, some toy programs like “tuxeyes” (an Xeyes variant), or Advent of Code.
  • The format does not include compression because it doesn’t need to. Just use something like bzip2 to get file sizes similar to PNG.
  • It doesn’t cover every use case under the sun, but it does cover the most important ones (imho). They have discussed using something other than RGBA and decided it’s not worth the trouble.
  • They refrained from adding extra baggage like metadata. It would have needlessly complicated things.
