TIL: Triathlon is hard.
Imagine you've had to swim, cycle and run one after another without stopping for a moment. That's how triathlon feels :D
- 1.5k(?) swim (33:55) 3:05/100m(?).
- 75k cycle (2:29:00) 30km/h.
- 15k run (1:30:28) 6:00min/km.
I hate swimming, I suck hard at it and just trying to survive waves, jelly fishes and sharks, but still think the overall results are not that bad for a guy, who could walk only with crutches 5 months ago.

My nutrition today was:
- 1 plate of plane spaghetti 2 hours before start (40g carbs?)
- 1 gel 15 minutes before swim (22g carbs).
- 2 x 750ml bottles (maltodextrine+fructose+water+combucha) 250-260g
- 6 gels (132g)
The course took me 4:42h.
444g total? :)

@nprofile…6ljk I didn't use stgit, but heard many times. From what I've read it seems like the first step towards patch-based VCS (darcs, pijul).
Now we have jujutsu and it seems to cover this niche in even more details with a great UX and (probably) underlying tech.

Magit is what has kept me sane using git all these years.
Interactive rebases, squashes, fix ups, hunk selection were comfy and fluent; experience is polished.
Also, Magit created a whole new cluster of UI interfaces. Transient is a thing!

One week with Jujutsu full-time: I've never been happier with VCS. I guess we don't come back to the git.
The only "project-wide C-z" feature is already huge, but there is so much more.
Finally VCS doesn't get in the way and feels so reliable and smooth.

In the meantime, I use jujutsu on 2 of my current projects full time. I do everything, including push/fetch via jj. (with a help of majutsu.el).
The third project have a lot of untracked and ustaged changes, so I'm a bit hesitant to switch it to jj right now. (technically nothing stops me from doing so, but I want to use migration as an opportunity to cleanup and commit all "ongoing" changes).
Anyway, jujutsu is fucking awesome, I enjoy every second using it.

@nprofile…j497 Yeah, the git backend is huge.
True, the way it works in darcs/pijul/jujutsu make so much more sense to me.
Another cool thing is that all the files are always tracked even if you never committed them.
You use it through CLI/GUI?

Another cool project I recently found is Quickshell.
A number of components for building shells using Qt Markup Language. I saw QML for the first time in 2011, and I didn't enjoy it, but today it looks very sane to me (and I understand it much better :D).
If I ever need to prototype a bar, notification center, application launcher or something similar I would go for that. At least will start with it.
Demos are pretty cute and impressive:

I wanted to try darcs and pijul vcs for quite sometime, but never had enough motivation, because it completely new ecosystems with different tooling.
Recently I learned about Jujutsu, which reuses fundamental ideas of darcs, but uses git as a storage backend, so I can use it with existing projects and tools.

I found a demo, and it is pretty neat and makes so much sense:

Always haven't been! :D
Emacs is self-documentend, extremely hackable, with a huge ecosystem and we don't have anything better yet.
But at the same time it is sluggish, single threaded, quite bloated, has a quirky extension language and tons of legacy.
Being a fan often means blindly ignoring the flows, and defending the tool in discussions no matter what. I prefer to be one step ahead, using my expertise to attack the tools I use the ways people wouldn't even think of.

@nprofile…047x Yeah, saw it. I'm not a big fan of emacs in general and its window management approach in particular :D But will take a deeper look at the implementation, can be useful as an example. Thank you for the link!

2026-03-20 09:28:55 UTC

TIL:
- river wayland compositor is written in Zig.
- it has a window manager separated from compositor.
(and both points looks great to me).
For last a few months, I was using niri and is very happy with scrolling wm approach. However, I would like to have something more hackable to tweak the details to my liking and try out new things. And I guess, river may be a good foundation for my experiments.
Kudos to Isaac for this project.

One of the reasons I don't like "Plain Text" is that you have to do this fucking trickery to get any useful syntax tree out of it:
https://blog.pulsar-edit.dev/posts/20231110-savetheclocktower-modern-tree-sitter-part-5/#markdown-and-front-matter
or just™ use regexp and get it working 60% of the time (e.g. as most language modes do in #emacs, or filetype's -syntax were in #vim).
P.S. Parsing with grammars (+nested grammars injections) is much more reliable than regexps, but still have a number of edge cases, where it fails.

@nprofile…dmr0, it's also cool that the implementation of this workflow took a couple dozens of minutes and this functionality could be implemented by the user itself as all necessary APIs are exposed by Arei.
https://git.sr.ht/~abcdw/emacs-arei/log/c348103
Another missing piece is a context switching (fibers, vats, debugger, etc), but it will take a bit more time to implement properly :)

On FOSDEM and Guix Days we were discussing an absence of REPL in Arei/Ares.
One of the concerns was: with in-buffer evaluation workflow in contrast to REPL/jupyter notebook we don't see the correspondence between an expression and the value of its evaluation. It can negatively impact user experience and also makes Arei harder for learning/exploring.
I mentioned that this can be addressed by eval-and-print-to-comment.
Here is the demo of how it works:

On GrapheneOS (Android fork) I use following keyboards:

Both open source, offline and all that.
Heliboard has all the nice features, including swiping, undo, cursor movement without touching input field, ultrabackspace and all that.
Sayboard works ok, but requires a lot of attention as often misstranscribes and don't recognize borrowed words/loanwords.

@nprofile…pldf Actually, there were a lot of improvements for Rust in Guix recently. I think the problem with Gyroflow is some custom build scripts requiring internet access or something like this. I didn't dive to much into exploring the issue of packaging it for flatpak.

@nprofile…pldf I don't run it yet. The packaging story seems far from perfect. There is no flatpak package as well. Luckily my footage seems ok with camera's built-in stabilization, so probably I won't bother packaging Gyroflow anytime soon. However, I would be extremely happy if someone will do it in the meantime.

About eval sessions: We already have a few nREPL sessions, which allow to run completion/gotodefinition/eldoc in parallel to long-running evaluation or multiple evaluations. With addition of hoot we will have not only "guile-eval" and "tooling" sessions, but also "hoot-eval" or maybe a few of thems and "hoot-tooling". We will need at least an automatic dispatcher based on GUILE/HOOT load paths, but also probably a UI for manual selection of eval session.

@nprofile…0v7r @nprofile…zwgs @nprofile…z8rp Also, in the context of exception eval constructs a special evaluation environment, where frame's local variables are available.

The same mechanism can be used for Goblin's VATs or fibers scheduler.
It's in PoC and also doesn't have a good explicit UI yet.

Cool, I saw some work on it, but didn't know if it finished. Pretty happy to hear it is! :)
Nested eval is similiar to what usual guile's repl provides, when exception raised or special meta-command is used. It sets up additional nrepl operations handlers and allows to show extra UI (like debugger window).

Looking for a book recommendation. Something light, probably adventurous and funny, for evening reading.
I was enjoying hpmor, Metro 2033 and S-T-I-K-S Universe, LOTR, litrpg, cozy zombie and postapoc lately, but it's just for the reference, I'm quite open for exploration.
If recommend the book, please add a couple of sentences from your personal experience with it.

I need to find out how to enable reasoning for the first one in gptel. I'm quite satisfied with the speed and quality and the tool finally became helpful for me for some use cases. Looking forward to see resource-efficient self-hosted models with good enough quality and speed.

2025-09-04 03:57:20 UTC

LLM-driven refactoring. A very viable LLM use case I found:
Sometimes, I ask LLM questions about a particular part of my codebase and when it mixes things up I see how a human can misunderstand this part of the project too.
I roll my sleeves up and make the naming and flow more explicit and verbose.

Debugging #AirQuality #3 (a lot of mold, gave up).
I think the air purifier was helping a bit and I felt slightly better. But a couple days ago, I found out:
- That the wall was covered with black mold and carefully painted over with white paint :blobcatfacepalm: (it started to grow through the paint).
- On the top shelf of wardrobe live two more types of mold carefully swept into the corner.
I gave up on my deposit, spend a day looking for a new place and moved out.

@nprofile…hcpm I ordered one from Japan (PM2.5, PM10, CO2), no tVOC unfortunately. It will come in a couple of weeks, so probably won't be too much relevant anymore.
Mold is detected as VOC? (I tried to look up the info about it, but could find a definitive answer).

@nprofile…muce Yep, quite unfortunate. I spend too much time dealing with it, while I could spend it working on my projects or enjoying the life any other way :/
I just hope it won't give long term consequences, the rest I will handle somehow :)

As you can guess sleeping and living in a respirator is not a sustainable option 😷 . As a more generic workaround I bought an air purifier. I have it on 24/7 and try to be out of apartment as much as possible.
I feel better now, I still not sure if it's cause of air purifier, but I hope it is and I hope to survive until the end of apartment lease (one more month).

Debugging #AirQuality #2 (humidity, mold, air purifier).
I got a hygrometer. It seems the avg humidity is 70+, under AC I couldn't get anything consistently less than 55.
Which means the cause of my respiratory problems is not an (anticipated) low humidity.
My new assumption that there is a mold (a circle of it in the shower, but it's probably in a living room too).
I've slept in respirator for one night, it was far from comfortable and the next day I found out a mold on it.

@nprofile…muce A few years. I wouldn't say it got back to norm, but at least I could walk more than a couple of thousands steps a day. Probably with a good physio therapist I could recover much faster, but I haven't had a much luck with medical systems.
A few more years later I even started to trail run and preparing to marathon, but one day I pushed too hard and reinjured it again by excessive tempo on downhill section :(

Injured my knee a couple times: falling from a cliff snowboarding and making a throw on wrestling competitions. Teared meniscus.
Ridding the bike on the road feels relatively safe and comfortable so far 😅 (I was in pain last night, but it's very different pain probably it's stabilizer muscles around the knee experiencing adaptation).
I hope you knee will get better. Take care of it. Can share some thought and experiences in private on knee maintenance if you wish.

BTW, knee wise, ridding the bike feels much more comfortable than running, probably even more comfortable than walking. Especially the down hill part.

Got this 67w little boi with 3 ports, instead of thinkpad's slim, but misbehaving charger. That means, I can get back to work and streaming tomorrow! 🥳 (doesn't mean I will 😄).
For those, who is not following the situation: during previous stream my laptop started to discharge, despite being plugged in. Turned out the problem in AC block, it can't hold 40w load steadily and from time to time stops charging or doesn't even start to :)

@nprofile…0jae Try guix shell --pure emacs emacs-arei -E '.*GTK.*|.*XDG.*|.*DISPLAY.*' -- emacs -Q to make sure that you get a clean up-to-date emacs env M-: (require 'arei) M-x arei
I suspect a stale version of emacs-arei may be leaking from your user's profile (the one one manages with `guix package`) or something like this.

I couldn't get the same problem with my current setup. make ares and M-x arei works flawlessly in guile-ares-rs repo.
BTW, before preparing reproducer, can you please checkout guile-ares-rs repo and try `make ares` and M-x arei in some of the project's scm files?

What version of arei do you use? What value (project-root (project-current)) returns?
We don't use github for development, it's only for mirroring. The primary forge for the project is sourcehut:

Ok, it seems the problem is on the charger side. The tablet also don't get enough power from it.
Maybe it's a damaged cable (will check it tomorrow) or in worst case scenario a problem with a power brick itself. Anyway, not a huge deal.
Thank you everyone for the help!

((@ (ares server) run-nrepl-server)) creates .nrepl-port and writes a port number into it, it automatically discovered by arei in the root of the project directory.
Make sure you start ares with CWD equal to the project root.

During the stream I noticed that my battery is discharging despite laptop's AC being plugged in.
After restart laptop stopped to boot. A few more attempts and 30 minutes later it somehow booted showed the message from picture, and upower showed the charge rate is 0 watt.
Went to the laptop service, they plugged their charger and it booted flawlessly and started to charge. I went to the cafe, plugged my charger and now it charges well again.
What the Schrödinger charger shenanigans?

After I spent the whole day researching the topic, I did following:
- Ordered Air Quality monitor from JP (CO2, PM2.5, PM10). ETA: 2 weeks.
- Ordered humidifier and simple hygrometer (humidity monitor) locally in Vietnam.
We have AC enabled the whole night and most of the day, so the air most likely is very dry. I will verify this hypothesis when hygrometer comes. Will return humidifier if I was wrong.

We are not done yet, much more is coming ;)
I have one more tiny tip on load paths: I would suggest to use different subdirectories for guile source code. Take a look at ares directory structure, we have src, dev, test and all of them serve different purpose and included in different scenarios.
If you add root project dir to the load path, a lot of unnecessary and sometimes unwanted things appears on load path, I would suggest to be more granular on this matter.
