@prologic@twtxt.net I’m trying to call some libc functions (because the Rust stdlib does not have an equivalent for getpeername(), for example, so I don’t have a choice), so I have to do some FFI stuff and deal with raw pointers and all that, which is very gnarly in Rust – because you’re not supposed to do this. Things like that are trivial in C or even Assembler, but I have not yet understood what Rust does under the hood. How and when does it allocate or free memory … is the pointer that I get even still valid by the time I do the libc call? Stuff like that.

I hope that I eventually learn this over time … but I get slapped in the face at every step. It’s very frustrating and I’m always this 🤏 close to giving up (only to try again a year later).

Oh, yeah, yeah, I guess I could “just” use some 3rd party library for this. socket2 gets mentioned a lot in this context. But I don’t want to. I literally need one getpeername() call during the lifetime of my program, I don’t even do the socket(), bind(), listen(), accept() dance, I already have a fully functional file descriptor. Using a library for that is total overkill and I’d rather do it myself. (And look at the version number: 0.5.10. The library is 6 years old but they’re still saying: “Nah, we’re not 1.0 yet, we reserve the right to make breaking changes with every new release.” So many Rust libs are still unstable …)

… and I could go on and on and on … 🤣

@movq@www.uninformativ.de I like this idea 👌 Very neat!

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():

@lyse@lyse.isobeef.org Rust is so different and, at the same time, so complex – it’s not far fetched to assume that I simply don’t understand what’s going on here. The docs appear to be clear, but alas … is it a bugs in the docs? Is it a lack of experience on my part? Who knows.

By the way, looks like there was a bit of a discussion regarding that name:

https://github.com/rust-lang/rust/issues/120048

@bender@twtxt.net Yeah, well, it’s a bit like twtxt. There is a Gopher community, but it’s small. I actually don’t like that HTTP is so easily accessible. I don’t like it that much when people post links to my site on HackerNews or something like that. Too much exposure.

Gopher is a small world. It’s slow and cozy.

And much like twtxt, the protocol is simple®, so it’s easier to tinker with it.

@prologic@twtxt.net yes, I never understood you using micro.blog (and paying for it, nonetheless!). I don’t like it (as a platform), and have an unexplainable dislike for its creator.

@prologic@twtxt.net I am finding writing my Notes very therapeutic. Just create a markdown file and commit, push, and it’s live. Whatever comes to mind, whatever I want to keep as relevant. Silly things, more like a dump.

If I feel like it, I do. If not, I don’t. Not social, not intended for anyone to see them. I am enjoying it!

@quark@ferengi.one It’s as close as coffee as you can get. 😅 They take the beans, apply magic, and then most of the caffeine is gone. You can also buy whole decaf’d beans and then grind them yourself. It does kill some of the flavor – but it’s not like you’re drinking black water.

@movq@www.uninformativ.de This was always my belief too re likes, etc.

@bender@twtxt.net Both Gopher and Mastodon are a way for me to “babble”. 😅 I basically shut down Gopher in favor of Mastodon/Fedi last year. But the Fediverse doesn’t really work for me. It’s too focused on people (I prefer topics) and I dislike the addictive nature of likes and boosts (I’m not disciplined enough to ignore them). Self-hosting some Fedi thing is also out of the question (the minimalistic daemons don’t really support following hashtags, which is a must-have for me).

I’ll probably keep reading Fedi stuff, I just won’t post that much, I think.

@lyse@lyse.isobeef.org That’s interesting, I see them (Teichrallen) everywhere I look. 🤯 It feels like they’re about as common as mallards (Stockenten) over here. 🤔

When I chose the MIT license for all of my software, I thought:

“Should I use GPL, which I don’t really understand? Is that worth it? Yeah, there is a theoretical possibility that some company might use my code in their proprietary product … and then what? Should I sue them to enforce the GPL? I’m not going to do that anyway, so I’ll just use the MIT license.”

And now we have those LLM scrapers and now it’s suddenly a reality that these companies (ab)use my code. I can see it in my logs. I didn’t expect that back then.

GPL wouldn’t help, either, of course. (Regardless, I now think that GPL would have been the better choice anyway.)

I’m honestly considering taking my code and website offline. Maybe make it accessible through some obscure protocol like Gopher or Gemini, but no more HTTP.

(Yes, Anubis might help. Temporarily.)

I’m just tired.
