Mixed feelings. On one hand, mut restriction is something that's going to simplify my code. On the other hand, it adds more complexity to the language and puts nonobvious semantics on what used to be plain data fields.

There's no shortage of reasons to hate nvidia. They still don't offer an open driver, and they infected the GPGPU landscape with their closed stack. The scientific computing needs are still expensive. That's before you get to their role in the recent hardware-related booms that many people view unfavorably..

Nah. They don't do exactly the same thing, but they do a similar thing. While I don't us either, I'm guessing they:
- find software
- resolve dependencies
- set up that software
which looks pretty much like package management to me.
Recently someone made me realize that the horrible github CI pipelines thing is just awful package management software:

I know because on my low-value laptop, I just never click the "restart" button after updates download.
But there's maybe a way to have your cake and eat it too. I recently evaluated OpenSuse MicroOs. There, you can't just install packages to the root file system, but you can into snapshots.
And the cool thing, there seems to be a command to switch to the new OS image at runtime.
I don't exactly know what it does yet, though.

2025-10-05 10:34:01 GMT

I think that's kind of unavoidable when you want a safe option.
Okay, suppose we can keep using the computer while the updates are running, but then you have to restart it immediately.
Oh no, people are complaining that they don't want to interrupt their work with a restart! Fair enough, let them continue working. But what happens next? They will keep the computer running for ages because why would they restart?
Not restarting ends up an insecure default.

2025-10-05 10:03:49 GMT

- reply

I'm glad you didn't notice any problems. But that didn't mean you were immune from them.
If your kernel has a security vulnerability, and you install an upgrade but don't restart, you're still vulnerable to it until you restart.
Due to how Linux retains files that were once opened, the same counts for applications, including those with network access.
So restarting is the conservative, safe option.
Use unsafe no-restart updates at your own risk (I do).

checking with Wikipedia gives BMI approximately 21.3, which is right in the normal weight range.

This doesn't cover a lot, and won't test kernel glue code at all - and glue is where most bugs are in my experience.
In the end, I decided to shove the complexity somewhere else, but at least the buffer manager can be tested somewhat.

Trying to create complex #software managing kernel buffers.
This needs tests.
"#functional core, imperative shell" - Testing management should not need the kernel.
I started mocking with a generic backend. Looks annoying.
"imperative shell"
The mocked generic is becoming a spaghetti horror.
"functional core" - and then it clicked.
I separated just the buffer manager, made it generic over buffer type. I can now feed it fake buffers and test it.

Libobscura is a friendly library to use cameras on Linux.

- get a RGB buffer in ten lines of code
- easy to add support for new devices
- no mailing list :P

I can only reply with:
a lot of pipelines are five minutes.

2024-11-11 06:55:06 GMT

- reply

Okay, another comparison:
the 5 minutes pipeline costs 82.6kJ * (300s/1400)s = 82.6kJ * 0.21 = 18kJ (*2 for network=36kJ)
A liter of gas contains 33.6MJ per liter, with car efficiency at 20% it's 6.7MJ, at 3l/100km it's 33.3km, so 200kJ/km.
Every 5m pipeline run costs about as much energy as 200/36=222m by a small car.
How far from the office do you live? How many commits do you push upstream per ride?
We have much better ways to curb energy use than not testing software.

2024-11-11 06:01:41 GMT

- reply

For comparison, boiling a cup of tea needs about 82.6 kJ of energy.
My CI computer has a 60W power supply (so it can't draw more power than that - we're overestimating). The CI would need to run for 82.6kJ/60W ≅ 1400s ≅ 23 min to match it.
Make it half to offset the energy costs of network communication: 11min.
That gives two 5min pipelines for the price of one hot drink.
Would you drink a cup on every other commit if it saved you time and stress in the future?
I probably would.

If your pipeline takes 2 minutes and saves 2 hours in debugging and another 20 in working around the problem at the end user side - which is the case at least for me - then the sweet spot is quite clear.

A piece of criticism to all code forges I know: why not run #CI on all commits?
A bad commit is a liability. It will break bisect and make debugging miserable.
#ForgejoActions takes it to the extreme and cancels an already running action when I push another change.
I get it - it's too slow and expensive to test them all when pipelines take minutes to run. But you could just pause the old ones until the newest one is finished!

Nah, that was the first thing I did :P

Installing #Fedora on a #Surface go 2. For #libobscura, because it has a special #camera setup (IPU3).
Set BIOS to boot from USB stick? Still boots windows.
You have to boot Windows with the stick in and select a special "Linpus Lite" reboot option.
Except if the stick is in while Windows is running, it will get corrupted and fail verification.
And then the installer aborts while formatting 'device is in use'.
#Windows resists being removed → fsck #Microsoft ,.

#libobscura, your friendly safe #camera library will be published this week.
But where do you want to see it?

#libobscura progress: a demo camera app!
So I've proved (some of) the concepts:
- API without segfaults
- zero-copy image passing
- GPU accelerated decoding
Yes, the picture is mirrored upside-down, why do you ask?
Next: clean up #GPU abstractions and publish a website.

Working on #libobscura today.
#OpenGL , #EGL , #glium , #glutin , #Rust , #v4l2 .
After 2 weeks of effort, the #GPU decoder COMPILES!
...The screen is green.
But hey, I actually know how to debug this :D It's almost as if 10 years of #debugging and #ReverseEngineering paid off!

I just found a way to let #Firefox use the #KDE file picker instead of the dreadful non-integrated #GNOME one :)
It involves enabling portal support:
In about:config set the key:
widget.use-xdg-desktop-portal.file-picker
to "1".
The "save" button is in the bottom right corner again :)

Remember internet.org? I heard in some places outside of Europe many people thought Facebook was the entire Internet.
It sounds like they want to tighten the grip on the rest of us. I hope this leads to an exodus back to the open Web,

Redefine the Four Freedoms? They better have an amazing proposal because they are already good.
Can show me what they are saying about wanting to redefine?

#Coding #OpenGL for #libobscura right now.
Computers need to convert those #Bayer or YUV #camera streams to RGB quickly to present them!
I'm just converting my old code to #rust, but it was enough to remind me why I hate the OpenGL + #EGL + #GBM combo. APIs with implicit global variables can get lost.
Thankfully, I'm nearly done and can go back to shaders and algorithms :-) but using GLES 1.2 (the #Librem5 can't do anything better ;_; )

No trainer, and it can (completely unscientifically) take 3-10km for the high steady pace to settle in. Depends on what you mean by "old people" though :)

Are you compressing the cursor together with the rest of the stream?
Some games have a "harware cursor" option to reduce cursor latency, where it skips the game's rendering pipeline to arrive a few frames early.
Something similar could be helpful for streaming: send cursor position separately from the video stream, render it directly from a saved image without waiting for an entire frame to arrive.

Does anyone in Germany(ish) want to get rid of a #RaspberryPi with a #camera ?
I need one soon to write a prototype driver for the #libobscura camera library project.
PM me with your price.

@npub1fus…tvjp Can a Taler wallet be used securely in the form of a card?
That is, a smart card that people insert at point-of-sale terminals?
The browser extension takes care not just of the secret store, but also of all user interaction. Would there be a need to trust the terminal not to be compromised?
What's the plan for everyday shopping anyway?

Some important names missing are Dillo and Falcon. Also Librewolf would be interesting to position here.

Your analogy is technically correct, but it also switches things from "act of god" (mateorite) to "predictable" ("space objects are documented") in the middle. This messes up the intuition I was asking about, on top of being unrealistic because we can't predict which house will get hit by a space rock so we don't have social norms for that.
A better one:
"You inherit a building. The building has an electric fault. Next year the fault causes a fire. Who are you blaming?"

My opinion differs in that it applies even when AI can do everything better.
And I only call mine an observation, without an emotional attachment like hope :P

Some people want an actual human to be present in the process, the same way Etsy is selling handcrafted items that may not be better than mass-produced ones.
If "Her" actually comes to real life, then some of those people may be satisfied with notes written by not-a-human. Some.
Either way, I don't see the need eliminated completely. Maybe the jobs would just gather too small a niche of customers.

Important social #research #survey !
You're using a community-based distro, free and full of MIT licensed software.
One day, you play some music, but your speakers make a loud POP sound and go silent forever.
A couple friends notice the same, and it turns out a bug in your favorite music player blows people's speakers.
Who are you blaming for the damage?

I deal with this by vendoring using copy-paste.
There are some legitimately useful crates that are under 100 lines, like assert_matches, which do eventually end up in the standard library.
And then there are crates like void.

I wonder what the story is with GPU acceleration on N900 now. The wiki page doesn't mention it, but the Imagination GPU is a big pain to support.

#Germany introduces a new system for accessing medical data online.
The implementation by my insurer: Android, iOS, Windows, #Snap Store. Sadly, it's not open.
Sensitive data + closed software on user devices = #security nightmare.
(I'm mercifully ignoring the inevitable leak of the central database.)
When will governments and banks learn? There's no security without source code. There's no stability without interoperability.

Time to gather the needed contacts before I begin with #libobscura next month!
#libobscura is going to be a proof of concept #linux #camera library which doesn't make the same mistakes as #libcamera . I'll base it on @npub1r3z…03cf 's work with #libmegapixels .

Sure is. btrfs-send is your friend. Yes, you do pay the cost of having to choose what you back up before backing up.
But you don't have to use btrfs-send either. Snapshot the entire drive, safely rsync, remove the snapshot. Also works, and without race conditions.

My 2 cents: btrfs snapshots.
