OpenBSD has the wonderful pledge() and unveil() syscalls:

https://www.youtube.com/watch?v=bXO6nelFt-E

Not only are they super useful (the program itself can drop privileges – like, it can initialize itself, read some files, whatever, and then tell the kernel that it will never do anything like that again; if it does, e.g. by being exploited through a bug, it gets killed by the kernel), but they are also extremely easy to use.

Imagine a server program with a connected socket in file descriptor 0. Before reading any data from the client, the program can do this:

unveil("/var/www/whatever", "r");
unveil(NULL, NULL);
pledge("stdio rpath", NULL);

Done. It’s now limited to reading files from that directory, communicating with the existing socket, stuff like that. But it cannot ever read any other files or exec() into something else.

I can’t wait for the day when we have something like this on Linux. There have been some attempts, but it’s not that easy. And it’s certainly not mainstream, yet.

I need to have a closer look at Linux’s Landlock soon (“soon”), but this is considerably more complicated than pledge()/unveil():

Of Pointlessware and CEOs
Had a moment, to check up on some of the companies, I stopped following, get to The Browser Company and see their newest product - it’s just Chrome, with an AI chat window pop-up and that’s it. Something Canary Chrome, come with already.
I see Theo from T3.gg, making fun of it on YouTube and promoting “his” product - an AI chat app, where you can choose from multiple models, by all the popular AI companies. Something I already have a worse version of, at work and I don’t even use it.
There’s also an interview, about the future of virtual keyboards, surely this is at least actually a real thing and not more pointless horse shit. I check the website of the keyboard SDK, and it’s around 20 identical apps, that just copy the same keyboard SDK/api and slap chatgpt features on top - in the App Store, these are surrounded by chatgpt clones, that just feed the users prompts, into the real thing and put ads, next to the answers.

YouTube just went from this:

To this:

Why.

Red for “activated” and dark gray for “deactivated” was easy to recognize.

Now we have light gray for “activated” and dark gray for “deactivated”. It’s clearly worse.

Why, why, why.

↳ In-reply-to » Sometimes things go wrong when buying CDs second-hand. I bought an album quite cheap – but as it turned out, they only checked the cover, not the content, so I got something else instead which is actually much more expensive. 🤣

The album I got by accident is starting to grow on me. Not that bad. 🤔 It’s Dredg – El Cielo, btw: https://www.youtube.com/watch?v=e4JB8rmXaO8&list=PLRASiMqDV8psZSFQi7nUX4p0R8oRHbUy_&index=1

What do you think I just learned about in this awesome Computerphile video with Matt Godbolt called “Subroutines in Low Level Code”? https://www.youtube.com/watch?v=1su3lAh-k4o

Here’s the plot twist, the phrase “till the cows come home”. Hahaha, I never heard this before, but I love it! It’s always interesting to me to hear English sayings. Sometimes we have the same in German, sometimes – like in this case – entirely different ones. It’s fascinating that even though one hasn’t come across proverbs, it’s typically still clear from the context what’s meant.

Yep, some unexpected language stuff. ;-)

Nobody want to be a shitty programmer. The question is: Do you do anything not to not be one?
Reading blogs or social media and watching YouTube videos is fun. After them, your code may be a little better, of course. But you need a lot. You need to study! Read good books and study the code of other programmers, for example. Maybe work with a new language, architectures and paradigms. You need break the routine.

If you know Object-oriented programming, you learn functional programming.
If you know Model-View-Controller, you learn Model-View-ViewModel.
If you don’t know anything about architectures, you learn Clean Architecture, Hexagonal Architecture, etc.
If you know Python, you learn Ruby or Go.
If you know Clojure or Lisp… you don’t need to learn anything else. You are already a good programmer. Just kidding. You can learn Elixir or Scala.

Be a good programmer my friend.

↳ In-reply-to » A mate and I had an amazing but also exhausting hike to the highest of the Three Emperor Mountains yesterday with perfect weather conditions. Sunny 18°C, blue sky with barly a cloud and a little welcoming breeze, just beautiful.

@prologic@twtxt.net @movq@www.uninformativ.de @bmallred@staystrong.run @ionores@twtxt.net Thank you! Yeah, the yellow meadows look truly awesome.

Watching “Happy People: A Year in the Taiga” in German the evening before, this thing totally looked like a trap to us. So, we decided to sit on another, more rustic bench nearby. :-) Oh neat, it turns out, there is a much longer four part series of the documentary in English on YouTube. Highly recommended! This is part one: https://www.youtube.com/watch?v=fbhPIK-oBvA

Judging by the surroundings, I think this is actually a forest altar or something of that nature. But it looks like they started with the chappel’s reinforcement steel and then they ran out of money before completing it or even placing the concrete forms. :-P

Yeah, 78 might be photo of the month. It’s one of my favorites.

↳ In-reply-to » 💡 I had this crazy idea (or is it?) last night while thinking about Twtxt and Yarn.social 😅 There are two things I think that could be really useful additions to the yarnd UI/UX experience (for those that use it) and as "client" features (not spec changes). The two ideas are quite simple:

The nice thing here is that any Ui/UX rendering for a “good user experience” is similar to what yarnd does for Youtube/Spotify/whatever embedding. Plus anyone can participate, even if they don’t really have a client that understand it, it’s just text with some “syntax” afterall.

Playing multimedia with Dillo
What if you want to use a web browser like Dillo, which lacks JavaScript support and can’t play audio or video inside the browser? Dillo doesn’t have the capability to play audio or video directly from the browser, however it can easily offload this task to other programs. This page collects some examples of how to do watch videos and listen to audio tracks or podcasts by using an external player program. In particular we will cover mpv with yt-dlp which supports YouTube … ⌘ Read more

anyway re: girl doxxing for wonyoung. this is real wonyoungism. i can only dream of being that iconic. for context wonyoung gets so much hate and she is literally my age and has been doing this idol shit since she was 13 and has gotten called all sorts of horrible things since then because people are jealous of her. so imo doxxing in her name is OK and justified i DON’T CARE there are youtubers in south korea who have made a career out of hating on her and are now getting sued by her for defamation
