TIL that Siemens has built a tiling X window manager called RTL in 1988 and the way tiling works in this is actually pretty cool

I love the stance #guix is hopefully taking on genAI with GCD 008: “Standing up for human crafting”:

kudos to @civodul@toot.aquilenet.fr for writing this proposal!

guess i'll dailydrive my heavily modified tinyrwm.c river hackery as my window manager now ... and I have to give kudos to the river project as it made hacking on wayland window managers approachable and fun for the past few months

i've been hacking on the tinyrwm.c example river provides for probably one or two months now and had that stupid idea to build a "tabbed mode" (what sway has at $mod+w) only window manager. It works surprisingly well, but will probably go back to the drawer of unfinished projects soon as I don't plan to maintain a river wm (or spend as much time with this experiment as I *actually* did)

@cwebber@social.coop SeL4 looks pretty cool! wdyt of capsicum (https://www.cl.cam.ac.uk/research/security/capsicum/) that seems to be used in BSDland? I don't know enough about it specifically, but it has been on my radar for a while & it could also be something worth looking into as it seems to go into a good direction?

@cbaines this looks awesome!

@janneke @guix @nlnet this is awesome news, congrats!

@civodul@toot.aquilenet.fr i'll try to get my v0.0.1 with this new output format to codeberg this weekend! always curious about feedback on how well it works/what's missing etc. am currently also experimenting with a "topology map" (numerical stats at which depth occur how many changes) and IoU per depth, but am unsure yet if that would be of any use (other than me having something to toy around in guile with and learn more guix internals which is awesome in itself) in practice

i think it's beautiful that every upgrade of a rust application has to include at least one ASCII art homage to an F-Zero vehicle* in its tree diff

• if anyone wants to take guesses which one is shown here -> https://mutecity.org/wiki/Machine

did some evening hacking on my derivation diff utility and experimented with the output format a bit more. It now shows whether an input has been added, removed or updated and if updated whether that's because of a version bump (v) or a hash change without a version bump (h). Haven't pushed the current version to codeberg yet, as I'm still trying out new ideas, learning about more and more #guix internals that simplify what I'm trying to do along the way, and the codebase is a mess because of that! (hope to abandon this hacky learning project utility in favor of a prospective guix store diff command in guix proper one day)

spend parts of my weekend having fun hacking on my diff-drv utility to diff guixes ATerm files. Implemented BFS traversal (to show which exact paths differ) as well as a IoU index (to tell how similiar two .drv graphs are) so it's easier to figure out what changed between two builds regarding the inputs. I'll push it to https://codeberg.org/theesm/diff-drv tomorrow (after cleaning up the branch a bit and after having prettified the output so it's consistent to the rest of diff-drvs output).

#guix

@tclaesson@mastodon.nu that's good to know, i'll include it in the table, thanks for checking

@gnu_slash_gabber@social.tchncs.de re embedded: I'll consider doing so, that seems to be a good idea! (at least for what can be tackled in the realms of guix already) re raspi: the u-boot package for raspi is a "bring your own firmware" kind of thing as well iirc, the rk3588 u-boot would be similiar to it, meaning one could upstream everything except for the rk3588_ddr_lp4_2112MHz_lp5_2400MHz_v1.18.bin and either rely on people inheriting the package and do modify-phases magic or maybe just upstream the whole thing to nonguix for the moment being.

I summarized my notes on what's already working/available in guix proper, what's missing and can/cannot be upstreamed, and what the general status of stuff required for running #guix system on the rk3588 mnt pocket reform is here: https://me.literatelisp.eu/guix-on-mnt-pocket-reform-whats-still-missing.html

#fosdem was pretty cool, especially this years declarative and minimal computing dev room (even if I missed the first few talks there!). already looking forward to the #guix days tomorrow
