@prologic@twtxt.net Yeah, it’s not a strong sandbox in jenny’s case, it could still read my SSH private key (in case of an exploit of some sort). But I still like it.

I think my main takeaway is this: Knowing that technologies like Landlock/pledge/unveil exist and knowing that they are very easy to use, will probably nudge me into writing software differently in the future.

jenny was never meant to be sandboxed, so it can’t make great use of it. Future software might be different.

(And this is finally a strong argument for static linking.)

Another example:

$ setpriv \
    --landlock-access fs \
    --landlock-rule path-beneath:execute,read-file:/bin/ls-static \
    --landlock-rule path-beneath:read-dir:/tmp \
    /bin/ls-static /tmp/tmp/xorg.atom

The first argument --landlock-access fs says that nothing is allowed.

--landlock-rule path-beneath:execute,read-file:/bin/ls-static says that reading and executing that file is allowed. It’s a statically linked ls program (not GNU ls).

--landlock-rule path-beneath:read-dir:/tmp says that reading the /tmp directory and everything below it is allowed.

The output of the ls-static program is this line:

─rw─r──r────x 3000 200 07-12 09:19 22'491 │ /tmp/tmp/xorg.atom

It was able to read the directory, see the file, do stat() on it and everything, the little x indicates that getting xattrs also worked.

3000 and 200 are user name and group name – they are shown as numeric, because the program does not have access to /etc/passwd and /etc/group.

Adding --landlock-rule path-beneath:read-file:/etc/passwd, for example, allows resolving users and yields this:

─rw─r──r────x cathy 200 07-12 09:19 22'491 │ /tmp/tmp/xorg.atom

Release Highlights:

This release focus on integration in a wider federated network, with support for spam fighting features, better compliance with Matrix network and native support for PubSub Server Information to have your server count as part of the wider XMPP network (for example, you can register your server on XMPP Network Graph).

@prologic@twtxt.net Yeah, this really could use a proper definition or a “manifest”. 😅 Many of these ideas are not very wide spread. And I haven’t come across similar projects in all these years.

Let’s take the farbfeld image format as an example again. I think this captures the “spirit” quite well, because this isn’t even about code.

This is the entire farbfeld spec:

farbfeld is a lossless image format which is easy to parse, pipe and compress. It has the following format:

╔════════╤═════════════════════════════════════════════════════════╗
║ Bytes  │ Description                                             ║
╠════════╪═════════════════════════════════════════════════════════╣
║ 8      │ "farbfeld" magic value                                  ║
╟────────┼─────────────────────────────────────────────────────────╢
║ 4      │ 32-Bit BE unsigned integer (width)                      ║
╟────────┼─────────────────────────────────────────────────────────╢
║ 4      │ 32-Bit BE unsigned integer (height)                     ║
╟────────┼─────────────────────────────────────────────────────────╢
║ [2222] │ 4x16-Bit BE unsigned integers [RGBA] / pixel, row-major ║
╚════════╧═════════════════════════════════════════════════════════╝

The RGB-data should be sRGB for best interoperability and not alpha-premultiplied.

(Now, I don’t know if your screen reader can work with this. Let me know if it doesn’t.)

I think these are some of the properties worth mentioning:

• The spec is extremely short. You can read this in under a minute and fully understand it. That alone is gold.
  
• There are no “knobs”: It’s just a single version, it’s not like there’s also an 8-bit color depth version and one for 16-bit and one for extra large images and one that supports layers and so on. This makes it much easier to implement a fully compliant program.
  
• Despite being so simple, it’s useful. I’ve used it in various programs, like my window manager, my status bars, some toy programs like “tuxeyes” (an Xeyes variant), or Advent of Code.
  
• The format does not include compression because it doesn’t need to. Just use something like bzip2 to get file sizes similar to PNG.
  
• It doesn’t cover every use case under the sun, but it does cover the most important ones (imho). They have discussed using something other than RGBA and decided it’s not worth the trouble.
  
• They refrained from adding extra baggage like metadata. It would have needlessly complicated things.

@movq@www.uninformativ.de Yeah that’s why I’m striking this conversation with you 😅 Not only do I respect your opinion quite highly 🤣 But like you say (and I’ve read their philipshpy) it can be a bit “elitism” for sure. I’m genuinely interested in what we think of as software that “doesn’t suck”. Tb be honest I haven’t really put thought to paper myself, but I reckon if I did, I’d have some opinions/ideas…

Thanks @bender@twtxt.net! Yeah, so super cute. I couldn’t pet them, though. Despite very curious, they were also very restless.

I persuaded my dad to check out the fireflies with me tonight. He only wanted to go for a short trip, so we came just across a couple hundred of them. Otherwise, the thousands mark would have been exceeded in no time. He was super glad I talked him into that. :-)

It was also my first time to see them over the meadows. Those numbers don’t compare to the ones inside the forest, no question, but we probably saw 60 or so. Haven’t come across them there before, I only heard and read about that.

Note to future-Lyse next year: Leaving at 21:45 seems like a good time. We left earlier and had to wait just a few more minutes for them to come out in masses.

Too bad it’s impossible to share photos or videos. My camera isn’t made for that at all, not even close.

@movq@www.uninformativ.de Yeah. :-( But hey, there are at least six of us using mail as it should be™. :-)

I sent the dealer an e-mail about that with all sorts of other issues as well. Let’s see if they fix anything of that some day. Or yet just even read it.

It all started in New York in the early 1980s. Click, now 85, and his friends were sitting at the long bar of the New York Athletic club reading magazine articles about boxing, fencing, judo and wrestling. “One of my mates said, ‘Dude, we don’t do any of those things.’” They had to face it. They were dull. They decided to embrace their dullness.

As a joke, they started The Dull Men’s Club, which involved some very silly, dull activities. They chartered a tour bus but didn’t go anywhere. “We toured the bus. We walked around the outside of the bus a few times. And the driver explained the tyre pressures and turned on the windscreen wipers.”

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():

@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.

@prologic@twtxt.net Yeah, it’s difficult, you often don’t get what you’d expect. They also make heavy use of 3rd party libraries. IIUC, for random numbers, they refer to this library. I’ve read many times that the Rust stdlib is intentionally minimalistic (to make it easier to maintain and port and all that).

I’m struggling with this, using 3rd party libs for so many things isn’t really my cup of tea. I’ll probably make my own tiny little “standard library”. It’s silly, but I don’t see any other options. 🤷
