Linux kernel hacker and maintainer etc.

I needed to check if files went to a generated image and by accident noticed that 7z is actually quite nice ad-hoc tool for checking such thing:

BTW, the only "professional network" I used while looking for a new position was #Mastodon. There could not be a better environment to find new and interesting opportunities.

If I could decide, I would block all services from the EU region, which require smart phone to bind into them. That is the only real need for smart phone in my life and I'd really like to switch to a basic phone.

In my block list would be at least BookBeat, Signal, WhasApp and Telegram. We should just ban them until they fix the situation :-) I'm sure SMS based binding is doable.

I just hate smartphones so much...

@ljs @lkundrak @davesh @ibboard imho Apples power adapter with the international sockets pack is the best 😉 i use it with all my laptops in travel. Livin’ socket agnostic is great!

@orva Yeah, I mean these days if I install an app, I found out that it is actually a software development platform with a plugin system ;-) This applies to surprisingly wide category apps.

After scanning ~40 pages of contract documents I just want to say that #GNOME Document Scanner rocks! No bullshit workflow, gets to job done. This is rare 👍

oops, went of the hook with this: https://lore.kernel.org/all/D400W37FR01S.CLFIKA98YWX7@kernel.org/

I think it would be pretty interesting idea to use BPF like this in kernel.

If #decentralized #services become a thing, I wonder if #mainframe 's make a strong comeback 🙂 They are machines made for transaction throughput.

Since there seems to be renewed interest in , I thought I'd have a look at the my CDE utilities from back then, which led me to my old Web page “Linux on a VAIO Z600LEK” http://dynalabs.de/mxp.old/vaio/index.html, because there's a screenshot of my work environment from back then. ⇢

@litchipi So my guess is that this lagging a bit behind, i.e. it might be that even tho GCC is already at 14.2 (at least in my Fedora system), this shows 14.0:

~/work/github/gccrs master*
$ $(find . -name gccrs) --version
gccrs (GCC) 14.0.1 20240309 (experimental)

So after reading around the Internet I got the picture that already GCC 14.1 could be able to compile Rust-Linux. Is this correct? Amazing progress if it is! I did not simply know this.

I'll give it a shot since 14.1 came out already at Spring if I recall correctly.

Update: I have now gccrs build ongoing, after that I'll just point it out to cargo with build.rustc-wrapper and see how it compiles user space code first. Very interesting and exciting ;-)

While making a track for Random Records [1] compilation I've noticed one and dumb and simple workflow improvement: for drum sounds hosted by a sampler in their own tracks it is best to keep key-tracking off.

Then the MIDI note values are free for Note Grid and for plugins like Effectrix 2. Saves tons of time because then no separate MIDI track is needed for triggering the effect.

Ie time to deliver the promise.

I mean if you money to pay for ext2 driver that we actually even don't need, you certainly have money to sponsor GCC.

It can be interpreted as an action where these companies try to purposely cause a toolchain lock-in. Not sure if that is even aligned with CoC. Please stop doing that.

#Microsoft and #Google should really put few million to GCC-Rust because they are the main corporate entities pushing the Rust code to the mainline.

Blame them instead of maintainers.

Here's something I don't understand: ext2 driver in Rust. Frankly, I just don't get why Microsoft spends money on stuff like that.

Ok, so here's something I WOULD get (assuming that it compiles with GCC because it is a hard constraint): re-write user space interaction points of ext4 driver in Rust and make it call the existing internals.

Then I'd have a patch at hand that is written in Rust and that makes a modest improvement for the sake of better security, i.e. something I can *measure*.

I really try to avoid thinking of liking or disliking patch. If I can measure an improvement that overrides the possible drawbacks, then I see no other choice than carry the patch forward.

@jani Because I'm idealist let's put my 5-7 year timeline guess to 2-5% ;-) As GCC-Rust starts to catch up that might give a boost that is hard to predict beforehand, and also because Firefox is quite distant comparison point.
