Sam Whited: Notes
I’ve recently been using the Mixxx software for DJs. This page includes some
personal notes on my own use cases, what’s good, what’s bad, etc.
It is not really made for general consumption, but is thrown up here anyways.
It will be a bit rambling and/or ranty at times, most likely.

Let’s get my overall impressions of the software out of the way up front: it’s
absolutely great and I recommend it over the commercial alternatives for DJs of

San Francisco Billboards - August 2025

** Make awk rawk **
A friend online recently replied to something I wrote about awk by saying:

[…] it’s a danged shame [awk] didn’t continue to evolve the way Ruby, Python, PHP have evolved over the decades.

I had exactly this thought while working on my slightly unhinged“lets see if I can implement a basic scheme using awk by writing an assembler and VM in awk,” skwak. Which eventually lead me to start noodling on how to layer in some modern niceties into awk, without breaking awk’s portability.

XMPP Providers: A Rising Tide Lifts All Boats

In May 2025, we ran a small survey to gather feedback from XMPP server operators.

While the XMPP Providers project currently lists a little more than 70 providers, this is a good turnout.

Hahaha, I first thought of https://www.youtube.com/watch?v=zA52uNzx7Y4 when I read @kat@yarn.girlonthemoon.xyz’s “lyrics”. ;-)

Doesn’t sound bad, I like it. The synth reminded me of some song by Beast in Black.

mandoc is nicer to read/write than the man macro package and, most importantly, it’s semantic markup.

HTML output is a bit broken in GNU groff, though (OpenBSD on the left, GNU on the right):

Still, I’m inclined to convert my manpages to mandoc.

37C3 and New Year’s Eve 2023
Another one from the vaults. The 37C3 conference took place in
December, 2023. This report was mostly written in January, 2024.
Mostly finished it at night in my cottage between 28 and 29th
December, then edited and added some stuff in July, 2025. So… Only
1.5 years late?

It was a little ironic, and a little sad, that I was finishing the

@movq@www.uninformativ.de According to this screenshot, KDE still shows good old application icons: https://upload.wikimedia.org/wikipedia/commons/9/94/KDE_Plasma_5.21_Breeze_Twilight_screenshot.png

And GNOME used to have them, too: https://upload.wikimedia.org/wikipedia/commons/9/9f/Gnome-2-22_%284%29.png

I like the looks of your window manager. That’s using Wayland, right? The only thing on this screenshot to critique is all that wasted space of the windows not making use of the full screen!!!1 At least the file browser. 8-)

This drives me nuts when my workmates share their screens. I really don’t get it how people can work like that. You can’t even read the whole line in the IDE or log viewer with all the expanded side bars. And then there’s 200 pixels on the left and another 300 pixels on the right where the desktop wallpaper shows. Gnaa! There’s the other extreme end when somebody shares their ultra wide screen and I just have a “regularish” 16:10 monitor and don’t see shit, because it’s resized way too tiny to fit my width. Good times. :-D

Sorry for going off on a tangent here. :-) Back to your WM: It has the right mix of being subtle and still similar to motif. Probably close to the older Windowses. My memory doesn’t serve me well, but I think they actually got it fairly good in my opinion. Your purple active window title looks killer. It just fits so well. This brown one (https://www.uninformativ.de/blog/postings/2025-07-22/0/leafpads.png) gives me also classic vibes. Awww. We ran some similar brownish color scheme (don’t recall its name) on Win95 or Win98 for some time on the family computer. I remember other people visting us not liking these colors. :-D

@kat@yarn.girlonthemoon.xyz I kind of like XML because it’s mostly well-defined and easy for humans to read (unlike YAML, which is a complete mess, imho) … and at the same time, it can get complicated really fast. 🫤 But at least it’s plain-text – that’s the important part in this case. 😅

Xfce does one thing very right: It stores its settings in plain-text XML files. This allows me to easily read, track, and maybe even distribute these settings to other machines.

(Unlike GNOME’s dconf, which uses some binary file format. Fun fact: The older and now deprecated gconf also used XML files.)

@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
