In-reply-to » linode's having a major outage (ongoing as of writing, over 24 hours in) and my friend runs a site i help out with on one of their servers. we didn't have recent backups so i got really anxious about possible severe data loss considering the situation with linode doesn't look great (it seems like a really bad incident).

@kat@yarn.girlonthemoon.xyz after 5 years or so with Linode, I started having little—but annoying—issues with them. Moved to Vultr and have been very happy with them since Ubuntu 16.04, so 9 years, and a little bit more.

In-reply-to » I was drafting support for showing “application icons” in my window manager, i.e. the Firefox icon in the titlebar:

@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

In-reply-to » I did a “lecture”/“workshop” about this at work today. 16-bit DOS, real mode. 💾 Pretty cool and the audience (devs and sysadmins) seemed quite interested. 🥳

@movq@www.uninformativ.de Interesting internal education sessions are way too infrequent here as well. There are a bunch of “knowledge transfer” meetings actually, but 90% of the topics already sound totally boring to me. The other 9% talks turned out to be underwhelming, sadly. I only attended a single one where it was delivered what has been promised. They’re all talks, not real hands-on trainings like you did.

Once a year the security guys organize a really great hacking event, though. Teams can volunteer to hand in their software dev instances and all workmates are invited to hack them and report security vulnerabilities. That’s a lot of fun, but also gets frustrating towards the end when you don’t make any progress. :-) There’s also some actual hands-on training in advance for preparation of the two days. Unfortunately, I missed the last event due to my own project being very stressful at the time.

When I had a Do What You Want Day I also show my direct teammates what I learned in the hopes of this being interesting to them as well. I’m the only one in my team using this opportunity, sadly.

Saw this on Mastodon:

18 rules of Software Engineering

  1. You will regret complexity when on-call
  2. Stop falling in love with your own code
  3. Everything is a trade-off. There’s no “best” 3. Every line of code you write is a liability 4. Document your decisions and designs
  4. Everyone hates code they didn’t write
  5. Don’t use unnecessary dependencies
  6. Coding standards prevent arguments
  7. Write meaningful commit messages
  8. Don’t ever stop learning new things
  9. Code reviews spread knowledge
  10. Always build for maintainability
  11. Ask for help when you’re stuck
  12. Fix root causes, not symptoms
  13. Software is never completed
  14. Estimates are not promises
  15. Ship early, iterate often
  16. Keep. It. Simple.

Solid list, even though 14 is up for debate in my opinion: Software can be completed. You have a use case / problem, you solve that problem, done. Your software is completed now. There might still be bugs and they should be fixed – but this doesn’t “add” to the program. Don’t use “software is never done” as an excuse to keep adding and adding stuff to your code.

In-reply-to » Over the past few weeks I've been experimenting with and doing some deep learning and researching into neutral networks and evolutionary adaptation of them. The thing is I haven't gotten very far. I've been able to build two different approaches so far with limited results. The frustrating part is that these things are so "random" it isn't even funny. Like I can't even get a basic ANN + GA to evolve a network that solves the XOR pattern every time with high levels of accuracy. 😞

This is one of my attempts:

$ go build ./cmd/xor/... && ./xor
Generation  95 | Fitness: 0.999964 | Nodes: 9   | Conns: 19
Target reached!

Best network performance:
  [0 0] → got=0 exp=0 (raw=0.000) ✅
  [0 1] → got=1 exp=1 (raw=0.990) ✅
  [1 0] → got=1 exp=1 (raw=0.716) ✅
  [1 1] → got=0 exp=0 (raw=0.045) ✅
Overall accuracy: 100.0%

In-reply-to » I guess mentions with .(s) / dot(s) like @eapl.me are valid? 🤔 Or nicks even? 🤔

on timeline the mention looks OK. Is there an issue on Yarn?

It’s an interesting topic. For example on Bsky it’s natural to allow domains https://bsky.social/about/blog/4-28-2023-domain-handle-tutorial

Although TwiXter only allows (letters A-Z, numbers 0-9 and of underscores)

Regex Isn’t Hard - Tim Kellogg 👈 this is a pretty good conscience article on regexes, and I agree, regex isn’t that hard™ – However I think I can make the TL;DR even shorter 😅

Regex core subset (portable across languages):

Character sets
• a matches “a”
• [a-z] any lowercase
• [a-zA-Z0-9] alphanumeric
• [^ab] any char but a or b

Repetition (applies to the preceding atom)
• ? zero or one
• * zero or more
• + one or more

Groups
• (ab)+ matches “ab”, “abab”, …
• Capture for extract/substitute via $1 or \1

Operators
• foo|bar = foo or bar
• ^ start anchor
• $ end anchor

Ignore non‑portable shortcuts: \w, ., {n}, *?, lookarounds.

In-reply-to » I updated wordwrap.[ch] to more closely match the interface for string(2); it's now just that plus a margin. I also updated litclock and marquee to match. http://a.9srv.net/src/index.html

@anth@a.9srv.net Hahaha, for a second I thought that you implemented word splitting according to Swiss (.ch) rules. :-D

Btw, both manpage links string(2) and getields(2) (it’s missing an f) point into nothingness: http://a.9srv.net/src/wordwrap.2.html

I can’t help but notice line 9: http://a.9srv.net/src/wordwrap.c

Interesting.. QUIC isn’t very quick over fast internet.

QUIC is expected to be a game-changer in improving web application performance. In this paper, we conduct a systematic examination of QUIC’s performance over high-speed networks. We find that over fast Internet, the UDP+QUIC+HTTP/3 stack suffers a data rate reduction of up to 45.2% compared to the TCP+TLS+HTTP/2 counterpart. Moreover, the performance gap between QUIC and HTTP/2 grows as the underlying bandwidth increases. We observe this issue on lightweight data transfer clients and major web browsers (Chrome, Edge, Firefox, Opera), on different hosts (desktop, mobile), and over diverse networks (wired broadband, cellular). It affects not only file transfers, but also various applications such as video streaming (up to 9.8% video bitrate reduction) and web browsing. Through rigorous packet trace analysis and kernel- and user-space profiling, we identify the root cause to be high receiver-side processing overhead, in particular, excessive data packets and QUIC’s user-space ACKs. We make concrete recommendations for mitigating the observed performance issues.

I run Plan 9 on my server and my main home workstation (a raspberry pi). My “daily driver” time is basically split between that and a Mac (excluding time on my phone, i suppose). I think it looks elegant, too. :-)

In-reply-to » This was interesting: I didn't expect so much variation in reported times. If you happen to have #plan9 running on some other VPS, I'd love to hear your results. https://pdx.social/@a/112481970480703254

For my purposes, the comparison would only be useful to systems running Plan 9; if you happen to have that, yes please!

Good idea. Plan 9 sets $NPROC on boot to the number of cores, so other things can use it. mk will dispatch things in just that way.
