Upgraded my system and switched from Nvidia to AMD for graphics - and a lot of random glitches and odd behavior is just gone!
Somehow this change also affected some UI element- and window geometries as well as shadows in KDE - not for the worse, it's just different. Very odd!

How nice, I love the new features we're getting in Linux lately, and especially this one!
Also I didn't know Christian Brauner is at Microsoft now - weirdly enough, MS apparently is quite an attractive employer for Linux engineers now (not bad at all!).

...of course, I can't be entirely sure it wasn't just feeding me a lot of bullshit ;-) - but it's answers did match reality so far.

I had ChatGPT explain to me the maddening world of LDAP (which was really opaque to me for a long time), and that was a super helpful experience!
I finally understand things like why order matters for DNs and other design decisions.
ChatGPT can be a very useful tool!

I ran the new #systemd ukify tool - unfortunately it didn't make me beans on toast or fudge, it didn't even set my locale to en_GB or change the wallpaper to the British flag. 0/10, do not recommend ;-)
Otherwise, an awesome 253 RC1!

... - including the coding style! It even made up some sensible reason for the function to exist, and wrote acceptable C code for it.
Then I told it to write a poem about that function... 😜
It truly is a lot of fun ^^

OpenAI's chat bot is absolutely wild! I just told it to generate some API documentation for a fake function in AppStream, and it did a decent job. Then I told it to do it "in the style of Matthias Klumpp", not knowing what that even means, and it wrote *exactly* what I would...

I just used simple textual smilies instead of unicode emojis in a message (like :-P ;-) :-D or ^^), and one "younger" (only by 6 years!) person was totally confused and had no idea what they were... We didn't even have emojis back in the day! I really feel old now...

It's out! We found that the railroad network (microtubule array) in neurites is extremely dynamic during development and moves retrogradely into the soma. New data compared to preprint - dynein, actin and much more. Get ready for lots of movies!🧵👇 science.org/doi/10.1126/sc (1/25)

So geht Populismus!
Zum Glück kann man genau nachschauen, wofür Katzen eingesetzt werden: Die 53 genehmigten Versuche seit 2014 dienen fast ausschließlich tiermedizinischen Zwecken. Es gibt ~17 Mio(!) Hauskatzen allein in D, die natürlich auch mal zum Tierarzt müssen.

Nicht nur Mäuse, Ratten und Kaninchen werden in grausamen Versuchen missbraucht – auch knapp 1000 Katzen werden pro Jahr in Deutschland beispielsweise in Taubheitsversuchen gequält.

I want to revive my old #Mastodon account, but mastodon.social is sooo slow! Every action takes 10-80 seconds! I also get tons of 504 gateway timeouts every so often. I wonder whether that's a sign of many people migrating very quickly, it was certainly better a year ago!

Ooof, this is bad! I don't think any company can use Copilot and also be *absolutely certain* that they are legally safe to redistribute "generated" code. Of course this will be worked out in court at some point (feels inevitable) but until then it just feels iffy...
Quote Tweet
@github copilot, with "public code" blocked, emits large chunks of my copyrighted code, with no attribution, no LGPL license. For example, the simple prompt "sparse matrix transpose, cs_" produces my cs_transpose in CSparse. My code on left, github on right. Not OK.

Also available as package in Debian's repos: sudo apt install debspawn
For adventurous users, debspawn 0.6.0 also allows booting containers that run custom commands, very useful for automated QA.

Debspawn 0.6.0 is out, for easily building Debian packages in #systemd-nspawn containers! The release contains a few QoL improvements and allows users to disable the built-in package caching, as well as using mmdebstrap instead of debootstrap.

Besides this, Syntalos 0.8.3 contains a ton of bugfixes and quality-of-life improvements, as well as a new tool to help with bug reporting.

The Flatpak bundle is still missing a few modules (like TIS Camera support), and despite some thorough testing there may still be some issues related to the isolated environment Flatpak runs Syntalos in. Please file any issues, so we can make the Flatpak experience great! ;-) 2/3

Really depends: Jokes in formal docs can be really confusing in a specification text, but in additional explanatory text that often follows up the hard facts with examples etc. they can make the text a lot more fun to read and easier to remember.

#InfinityTrain is by far one of the best-written series I have ever seen and well worth the watch, no matter how old you are - Especially if you like bitter-sweet entirely character-driven stories.
So, borrow a DVD or, well, watch it somewhere where you still can ;-)
Quote Tweet
Every 'Infinity Train' update so far:
- Removed from HBO Max along with many other shows
- Every Video on Cartoon Network's YouTube channel has been removed
- Soundtrack is no longer available to stream on ANY music platform
- New DVDs are no longer available for purchase

Constexpr? Finally real enum types? (Limited) auto type inference? Oh yes please! I want it now! Didn't expect C23 to have so much in it, the last revisions had extremely few changes. Now it will just take forever until I can actually default to it :-P

My laptop is literally disintegrating in front of my eyes... (old plastic/rubber...)
But what is amazing is that compared to when I bought the device ages ago, nowadays Purism, system76 but also Dell and Lenovo all seem to have great offerings for laptops with Linux by default!

Do you need to record time-synchronized data from many cameras, Miniscopes, electrophysiology amplifiers etc, or have an open-source tool to control closed-loop behavior experiments with ease? Then come to my poster on the Syntalos project today at #FENS2022! (S07-415)

If you work with hardware, try Minian! It performs incredibly well with my data and is definitely worth a look! (And can be automated, if you don't need interactivity all the time)
Great work by Phil Dong et al :-)

The Fedora firmware proposal[1] is good, but how much better would it be if there was one place shipping AppStream metadata[2] for firmware so every distribution could use this the same way, maybe with some nice GUI? ;-)

This might be the biggest accidental advertising for open source soft- and firmware as well as sane update policies that I have ever stumbled upon. Bug in a light switch firmware? Tough luck if you run out of vendor support...

Happy #OpenSourceFriday!
I have a request for all y'all #OpenSource folks: what are some pivotal moments in open source history? Try to think beyond the usual suspects (licenses, operating systems, etc...).
RT for reach please?
