My friend David Adler (@davidrkadler), a Jewish-American who was on the flotilla and was kidnapped by the Zionist regime, is detained illegally in an Israeli prison and no one has had contact with him for four days.

Shamefully, the US government has done nothing to help him.

Don't let anyone ever tell you that Zionism is about the protection of Jewish people. Zionists reserve special hatred for Jews who reject their genocidal project and who insist on the equal humanity of Palestinians.

X is where you find the people who think they run the Internet.

Bluesky is where you find the people who think they ought to run the Internet.

Mastodon is where you find the people who actually do run the Internet, and kind of wish they didn't.

"Amid the rise of artificial intelligence, technophobes and Luddites have continued to insist that machines “can’t really write”—at least not the way humans can. Those naysayers will be hard-pressed to wave away The Great Gatsby, the debut novel from the super-advanced Xerox 914 photocopier—an exciting new voice that wrote Gatsby after being trained on a data set comprising a paperback copy of F. Scott Fitzgerald’s The Great Gatsby." https://www.mcsweeneys.net/articles/book-review-the-great-gatsby-by-the-xerox-914-photocopier

I use Tailscale for home purposes, mostly so I can access movies from other locations without having to deal with reverse proxies and security. It's great software. I'm just saying this as preface: I would recommend it to anyone looking for a remote networking solution.

Yesterday they sent out an email about various events they would have a presence at, general marketing stuff, mostly in tech hubs and cons. Nothing remarkable. One of the events was that they were sponsoring a family movie night with another company. The movie picked was Harry Potter, but most people don't care, and it's a fine family movie. I shrugged and moved on with my day. Life's too short to get pissed off about stuff like that.

Well, today they sent out an email apologizing for the choice of movie and promising to do better in future.

I'm not stanning a corp. I wish there were a decent open-source option (well, they're built atop the open-source option, but goddamn do they make it easier). But it was nice to see. In a world which has gone full-on transphobia and doesn't seem to think that Jowling Kowling Rowling is worthy of comment, I guess enough technical people who use Tailscale aren't assholes and complained, or who knows, maybe someone at the company pointed it out, but whatever the reason, they rethought the movie choice. And they didn't just do it, they apologized for it to everyone on their mailing list.

It's a small thing, but I thought I'd share it both to say that I will continue to use Tailscale because it really is good software, but also if you need a nice thing, I guess this is a nice thing.

"These rent-seeking chokepoint obsessives have one move: corner a market and squeeze. They've been ratfucking renewables for decades because it competed with their existing racket.

But they aren't emotionally committed to setting fire to old dead things – they're just nature's most compulsive toll-booth operators, and they're sure as shit going to be looking for ways to stick toll-booths in our renewables future." - @pluralistic

John Oliver hat 10 Minuten über #Bernd das #Brot gemacht und erstaunliche charakterliche Übereinstimmungen festgestellt. 😂

The #Rust based Binder driver has hit linux-next and thus is slated for inclusion in #kernel 6.18. Congrats to Alice and everyone who helped making this possible!

From the patch description (https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=eafedbc7c050c44744fbdf80bdf3315e860b7513):

""We're generally not proponents of rewrites (nasty uncomfortable things that make you late for dinner!). So why rewrite Binder?

Binder has been evolving over the past 15+ years to meet the evolving needs of Android. Its responsibilities, expectations, and complexity have grown considerably during that time. While we expect Binder to continue to evolve along with Android, there are a number of factors that currently constrain our ability to develop/maintain it. Briefly those are:

1. Complexity: […]
2. Things to improve: Thousand-line functions, error-prone error handling, and confusing structure […]
3. Security critical […]

The biggest change is obviously the choice of programming language. We decided to use Rust because it directly addresses a number of the challenges within Binder that we have faced during the last years. […]""

I enjoyed this devious snippet for overriding malloc/free at runtime on the assumption that a program's authors can't be trusted to use them properly.

New blog post: "Using eBPF to add arbitrary delay to kernel functions"

Decided to try out writing a utility to add arbitrary delay to kernel functions, as a debugging aid.

And yes, I did manage to stall my laptop while implementing this; thank you for asking! :)

At the eBPF workshop, Panayiotis Gavriil introduced uXDP, a new XDP runtime that allows you to run unmodified, verified XDP programs on top of DPDK or AF_XDP. uXDP was able to improve the performance of an unmodified Katran by 40%!

Traditional profiling tools can introduce a lot of overhead when tracing XDP programs, especially for small programs. At the eBPF workshop, Vladimiro Paschali presented a new tool tailored for XDP that significantly reduces that overhead.

Someone asked me if I was ready for the fall and it took me a minute to realize they meant autumn and not the general collapse of society.

the punishment is a bit medieval but i appreciate the enthusiasm

As a consoling thought, when you look outside of the so-called "Western World", it becomes clear that #FossiFuels have already lost.

The surge in #fascism around here is in part a last-ditch effort to prop up a failing business model. This might "work" for a while, but it can only delay the end of the Fossil Fuel Age, not stop it.

Which doesn't make fighting fascism unimportant, of course. Any harm we can stop, we should. But they _will_ lose this, in the end.
