Trying and learning different bug tracking and project management tools for the last few weeks (bugzilla, debbugs, track, redmine, gitlab, taiga, plane, forgejo, phabricator, gitea, sourcehut and a couple more) I have to admit that the most convinient, visually pleasant and functional enough is GitHub Projects :/

I couldn't fit it in a short message, so I wrote a note about workflow:

Fun fact: After calling `join-thread`, you still can get #f from `thread-exited?`

Did you know that you can follow sourcehut repos via RSS?
This is how 30 hours of my work on guile-nrepl this week looks like:

One more reason why it's hard to use alists as associative data structure: There is no built-in destructuring capabilities for it. It seems (ice-9 match) is no help here. Situation becomes even worse if we have a nested data structure.
Going to stack a bunch of let+assoc-ref's I guess.

@npub1kpp…4ysc Good, I already scheduled a couple of sessions. I updated a list of people to pair with, will write you, when will be scheduling next sessions, ok?)

Also, I would like to see your toolbelt and how you program in #scheme.

I have guile-nrepl, rde, guix and a hundreds of related tasks.
Probably I would like to do something guile-nrepl related.
https://git.sr.ht/~abcdw/guile-nrepl
Need to write integration tests, learn more about fibers, add interrupt op, improve session management, maybe add middlewares.

2023-08-15 08:55:41

During the following month I want to make a few pair programming sessions (one, maybe two per week) with different people.
1. To work more focused on particular tasks and projects.
2. To see how other people work and learn from peers.
3. To share some experience.
4. To cleanup and optimize inefficient workflows.
5. To talk with folks in person, not only via toots/emails.
Like 1-2 hours informal coding session.
Ping me if you would like to hack with me! :)

@npub1r4m…968p Swapping capslock and control key probably is the simplest solution that can drastically improve the ergonomics in this case.

Through my life I have visited around 20 countries and I dream someday to write down my trips somewhere.
One of the tools I found for this matter is this nice FOSS web frontend project on top of OpenStreetMaps:
https://leafletjs.com/
It doesn't mean I would go crafting some travel blog now, just like to share cool FLOSS projects.

I like articles that were written more than 10 years ago, but are still relevant. This is true ever green content.

On the lalambda summer school a chip archiecture from Samsung asked me what's new in #lisp since 1980s. After a long talk, I asked him about #riscv and the summary is following:
- RISC > CISC (perf/power consumption, required number of engineers, simplicity)
- RISC-V is basically a MIPS with some minor fixes and refactoring.
- RISC-V > ARM/MIPS due to absent of architecture fees.
- All major big techs incorporating RISC-V in their devices.
- RISC-V is growing, hyping and will keep growing.

I'm preparing a dev environment for my modern lisps course for lalambda summer school and it's actually a pleasure. I constructed it in 30 lines of code and students only need to have guix installed, that's it.

Lack of a built-in associative array/map in Scheme regularly hits and bothers me. It's so generic and so useful, maybe we will add it in r8rs?
Alists doesn't work here not only for performance reason, but because we can't distinguish empty list and empty alist.

Today I received the first payment for the Free and Open Source Software work. It's of course is not a sustainable business yet, but a good step towards.
