As always these days, I'm the only person ๐Ÿ˜ท'd on my flight.

The air is awful on this equipment: 1925 ppm of COโ‚‚ at my seat.

Person next to me has a productive cough โ€ฆ๐Ÿ˜ฎโ€๐Ÿ’จโ€ฆ (can tell by sound), yet she isn't masked. ๐Ÿ™„

Welp, whatever ๐Ÿฆ  she's spewing on this row, I guess I'm bringing it to .๐Ÿ˜”

As a reminder for those coming to @fosdem โ€ฆ please mask! It's not life-or-death anymore for most, but I lost a month of work (& missed my OWN keynote) last year when I got at FODSEM.

NGC 55: A Galaxy of Nebulas

Can you see nebulas in other galaxies? Yes, some nebulas shine brightly enough -- if you know how to look. Clouds of hydrogen and oxygen emit light at very specific colors, and by isolating them, astronomers and astrophotographers can reveal structures that would otherwise be too faint to notice.

 This deep, 50-hour exposure highlights glowing hydrogen (red) and oxygen (blue) across galaxy NGC 55, viewed nearly edge-on. Also known as the String of Pearls Galaxy, NGC 55 is often compared to our Milky Way's satellite galaxy the Large Magellanic Cloud (LMC), although NGC 55 lies much farther away at about 6.5 million light-years. The resulting image uncovers a sprinkling of emission nebulas within and sometimes above the galaxy's dusty disk, offering a detailed look at distant star-forming regions.

Al Jazeera journalist Nour Odeh explains that babies born in Gaza since 2023 have not been registered, leaving them unrecognized by Israel and creating serious legal complications.

With no official registration, their status remains undefined: it is unclear how these children could leave Gaza, what documents they would be able to travel with, or whether Israel would permit their return if they ever managed to exit.

I just got a message from somebody saying I should read his book that he got AI to write about about how to get the most out of AI.

At least when a tree falls in a forest you can definitely say something happened.

I am working on a new project, called minimitra.

It's a FEP-ae97 client that implements Mastodon API. Minimitra is similar to Mitra, but it is designed to run as a desktop application and supports portable accounts. That means: offline-first, full identity/data ownership, Tor/I2P friendly.

Currently minimitra can only send and receive public messages, but I expect that porting features will not be difficult because most of the code will be shared.

Other limitations / downsides:

- Requires postgresql server.
- Can't post to multiple gateways.
- No cross-client portability.

Fortunately, all of that can be fixed!

I feel like people who are using LLMs for their work are not considering the motives and impact of the corporations hosting and serving the model. The goal isn't to make you a better developer, or even a more productive developer, its to make you dependent on their service and start driving up the rents to access it.

The goal is to extract your time, your money, and your knowledge feeding these models your plans for the work you want to achieve. They are not benevolent.

but with the aud check in Good, the only way a Bad feed could do this is by asking user to oauth into Bad feed itself (and thus giving it enough authority to call PDS and then call Good feed with a token)

A company claimed it built a web browser from scratch using AI. It wasn't true.

> ...for all that time and money, independent developers who cloned the repo reported that the codebase is very far from a functional browser. Recent commits do not compile cleanly, GitHub Actions runs on main are failing, and reviewers could not find a single recent commit that was built without errors.

> Where builds succeeded after manual patching, performance was abysmal, with reports of pages taking around a minute to load and a heavy reliance on existing projects like Servo, a Rust-based web rendering engine, and QuickJS, a JavaScript engine, despite "from scratch" claims.

"gee it would be nice if i could see every time a given kernel function gets called... too bad i'd have to recompile the kernel and reboot to insert a print"

well guess what. you don't need to, because ftrace exists, and it can do that and also a bunch of other stuff.

it apparently existed since 2008

i just watched a 15 minute demo of what it can do and... wait, why didn't i know about this sooner? https://www.brendangregg.com/blog/2016-12-27/linux-tracing-in-15-minutes.html

RE: mastodon.social/@FirewallDrago

Thank you to @FirewallDragonsFirewalls Don't Stop Dragons for covering the AI age verification bill being considered in the Florida Legislature! Between this and the Florida App Stores Accountability Act, we have our work cut out for us.

If you live in Florida, please call your state legislators and tell them you oppose these age verification bills!

Hootsuite signing a contract with ICE in this environment is profoundly shameful.

They know very well their social media monitoring tools will be misused to attempt to punish ICE's targets and citizen protestors.

We deleted our account with them, others should too!

@cwebberChristine Lemmer-Webber @jfredJonathan Frederickson @vagrantcVagrant Cascadian this also has the advantage that it wouldn't be as slow as GRUB to decrypt your disk, and if you wanted to you could avoid entering your disk encryption password twice by either putting the key into the second (encrypted) initramfs (although this has security implications for LUKS2 because it makes the key accessible from userspace) or possibly using kexec handover (which I'm not sure how to do, or if it would require kernel modifications, but that is a thing)
