@lyse I honestly wish I could do more than just sit here and wait. Itβs just a matter of time until they remove X.Org from the repos. π«€ But I really canβt dedicate so much time to this β¦
I give up.
Letβs try again next year. I donβt have the stamina. Death by a thousand paper cuts.
Canβt set up a meaningful taskbar: https://github.com/labwc/labwc/discussions/2924 (This is not a labwc issue, itβs a generic issue in the broader Wayland ecosystem.)
@bender Even I donβt believe in that anymore. :'(
@lyse Donβt remind me about Morse. I really wanted to learn that and tried so for quite a while, but no success. π’
@aelaraji And I read the following funny response to that:
Bluesky: Users verify their age by adding a payment method or uploading a photo ID.
Mastodon: Users verify their age by posting pictures of the vintage computer equipment in their homes.

(β¦ maybe followed by βtmux Thursdayβ to cool down β¦)
@lyse 06.jpg is quite funny. Block the road for 30 minutes! %)
@bender Hm, it is now. π€ I should have made a screenshot when I first saw it.
@prologic Yeah, itβs not a strong sandbox in jennyβs 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 canβt make great use of it. Future software might be different.
(And this is finally a strong argument for static linking.)
Looks like hereβs something wrong with Markdown parsing. π€ The original twt looks like this:
>This extension was turned off because it is no longer supported
Thanks Google.
This browser was uninstalled because it absolutely sucks!
So only the first line should be a quote.
Landlock is still young and a bit unpolished, but itβs slowly getting more popular. π₯³
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. Itβs 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:
βrwβrββrββββx 3000 200 07-12 09:19 22'491 β /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 β 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:
βrwβrββrββββx cathy 200 07-12 09:19 22'491 β /tmp/tmp/xorg.atom
st tries not to redraw immediately after new data arrives:
https://git.suckless.org/st/file/x.c.html#l1984
The exact timings are configurable.
This is the PR that changed the timing in VTE recently (2023):
https://gitlab.gnome.org/GNOME/vte/-/issues/2678
There is a long discussion. Itβs not a trivial problem, especially not in the context of GTK and multiple competing terminal widgets. st dodges all these issues (for various reasons).
Yeah, little fellow. I also just want to walk away. https://movq.de/v/bef8c35f01/ach.mp4
@lyse Yeah, if thereβs no stable API, then itβs not a lot of fun β¦ Bah. :|
β¦ but you canβt set SDL_VIDEODRIVER=wayland
globally, because that breaks Wine again β¦
β¦ okay, the SDL backend works if you also set SDL_VIDEODRIVER=wayland
.
@lyse dmenu is a great example.
There have been several attempts at porting dmenu from X11 to Wayland. Well, not exactly βportingβ it, more like rewriting it from scratch. Turns out: Itβs not that easy.
dmenu is super fast and reliable. None of the Wayland rewrites are (at least none of the popular ones that I know of). They are either bloated and/or slow.
It takes a lot of discipline and restraint to write simple software and not blow up the codebase. This is much harder than people think. Itβs a form of art, really.
@lyse I do my timetracking in a little Python script, locally. Every now and then, I push the data to our actual service. Problem solved β but itβs a completely unpopular approach, they all want to use the web site. I donβt get it. Then, of course, when itβs down, shit hits the fan. (Luckily, our timetracking software is neither developed nor run by us anymore. Itβs a silly cloud service, but the upside is that Iβm not responsible anymore. π€·)
Some of our oldschool devs tried to roll out local timetracking once, about 15 years ago. I donβt remember anymore why they failed β¦
This is developed inhouse, I'm just so glad that we're not a software engineering company. Oh wait. How embarrassing.
Oh to be anonymous on the internet. That must be nice. π
β¦ but the SDL backend is broken as well, albeit differently β¦
@prologic Yeah, this really could use a proper definition or a βmanifestβ. π Many of these ideas are not very wide spread. And I havenβt come across similar projects in all these years.
Letβs take the farbfeld image format as an example again. I think this captures the βspiritβ quite well, because this isnβt 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:

The RGB-data should be sRGB for best interoperability and not alpha-premultiplied.
(Now, I donβt know if your screen reader can work with this. Let me know if it doesnβt.)
I think these are some of the properties worth mentioning:
@prologic Hm, I wouldnβt say that. Go code could fall into that category as well.
Maybe this topic could use a blog post / article, that explains what itβs about. Iβm finding it hard to really define what βsuckless-like softwareβ is. π€ (Their own philosophy focuses too much on elitism, if you ask me.)
@prologic Ah, Iβm referring to software thatβs similar to that of suckless.org: Small, minimal codebases, small tools, but still useful. dmenu is probably the best example and also farbfeld.
Hereβs the author of Anubis talking about some of their experiences:
https://xeiaso.net/blog/why-i-use-suckless-tools-2020-06-05/
(You can skip the long config and keybinds part.)
@eldersnake This wasnβt always the case, though. Quake3, Quake4, Unreal Tournament 99 and 2004 are examples of games that used to run very well as native Linux games. But that was 20+ years ago β¦
@lyse (Itβs either that, or the fact that itβs womenβs football and βnobody wants to see that anywayβ.)
In all fairness, GOG says that Forsaken is only supported on Ubuntu 16.04 β not current Arch Linux. If you ask me, this just goes to show that Linux is not a good platform for proprietary binary software.
Is it free software, do you have the source code? Then youβre good to go, things can be patched/updated (that can still be a lot of work). But proprietary binary blobs? Very bad idea.
@lyse I have to say, this sounds much worse than our stuff at work. π«© (We donβt use any Microsoft services, at least not for core tools.)
@lyse Uffpuh. Es Wetter spielt verrΓΌckt. π«€
@prologic Bah! Why canβt we all have mild weather. π₯²
These are lists in your Inkscape example, right?
The font stuff? Yeah, thatβs a scrollable list where you can select the current font.
@prologic Heyho, welcome back. π Did you guys have a nice trip? π
@lyse Probably. :-) I just saw that the account on Yarn is also gone. Maybe it didnβt survive the crash earlier this year.
@arne Stattdessen rutscht er seitlich vom Tisch? π€ͺ
@lyse I can confidently say that I donβt remember ever having seen fireflys. (Nor Firefly.) π³ Iβm most surprised that you could count them. Naively, I would assume that these guys move around a lot and youβd lose track of them?
They're all talks, not real hands-on trainings like you did.
I love listening to good, well-structured talks. Problem is, not everybody is a good speaker and many screw it up. π₯΄ Iβm certainly not a great speaker, which is why I gravitate more towards βworkshopsβ, in the hopes that people ask questions and discussions arise. Doesnβt always work out. π€£ At the very least, I almost always have some other person connect to the projector/beamer/screenshare and then they do the stuff β this avoids me being wwwwaaaaaaaaayyyy too fast.
We are usually drowned in stress and tight deadlines, hence events like today are super rare β¦ We used to do it more often until ~10 years ago.
Once a year the security guys organize a really great hacking event, though.
Oh dear, Iβd love to participate in that. π€― That sounds like a lot of fun. (Why donβt we do this?!)
@prologic This person isnβt particularly happy with this study:
https://mastodon.social/@grimalkina/114717549619229029
I donβt know enough about these things to form an opinion. π«€ I sure wish it was true, though. π
@lyse Multi-Threading. Is. Hard. π€― And yes, that blog is great. π
@lyse lol β I explicitly kept them in there so that the code is easier to understand for non-Rust people π€ͺπ
@prologic Iβd say: Yes, because in Go itβs easier to ignore errors.
Weβre talking about this pattern, right?
f, err := os.Open("filename.ext")
if err != nil {
log.Fatal(err)
}
Nothing stops you from leaving out the if
, right? π€
(Of course, if weβre talking about a project youβre doing for a customer and the customer keeps asking for new stuff, then youβre never done, and you have to think ahead and expect changes. Is that what they mean? π€)
@kat I might give it a shot. π
Skimming through the manual: I had no idea that keeping the βupβ cursor pressed actually slows you down at some point. π€¦
@aelaraji I use Alt+.
all the time, itβs great. π
FWIW, another thing I often use is !!
to recall the entire previous command line:
$ find -iname '*foo*'
./This is a foo file.txt
$ cat "$(!!)"
cat "$(find -iname '*foo*')"
This is just a test.
Yep!
Or:
$ ls -al subdir
ls: cannot open directory 'subdir': Permission denied
$ sudo !!
sudo ls -al subdir

@kat I like the animations in your version much better than the ones from ExtremeTuxRacer. π And thereβs no little dance at the end of a race!
I also just noticed that the performance issue doesnβt affect all games. π€ Sigh, Iβll just downgrade for the time being. Not in the mood to fiddle with this.
