Big shout out to @jonthegeek.com , @frankiethull.bsky.social , and the folks behind @tidierjl.bsky.social for their work making this happen.

Congratulations Botswana! A significant first step into this arena.

Overall, I'm bullish on jj, and would've adopted it right away if:
I was in an earlier stage of my git journey (eg. if I needed ohshitgit.com)
or
I had to work with conflicts or complex history rewrites more often (eg. every other day instead of week or month)

For now, I'm giving Sapling VCS a try.

-7. Bookmarks appear too subdued visually and in general feel awkwardly integrated, the UI workflow could be better here.
And I really hope `push -c @` doesn't become common: branch names in PRs/MRs are a small but useful signal. Making them all `push-xoanfcah` makes for a worse repo experience.

-5. it can't use your ssh config, so if you have multiple keypairs, ssh-agent seems your only option

-6. the docs can be just as inscrutable as git's documentation a lot of the times

-3.1. Other small inconsistencies like: `jj new xy` instead of `jj new -r xy`. Both work, but the former seems much more common

-4. Signs of immaturity: unavoidable issue in WSL on Windows filesystem because of no core.fileMode option (no real workaround, a PR has been in the works for a while)

+3. The UI wins in visual presentation too, great use of colours and Unicode graphics
-3. Not as consistent as I'd like it to be though: the "automagic" empty commits created for the sake of squash workflows makes things unpredictable sometimes, eg. `prev` moving back two commits instead of one

+2. `jj undo` by itself almost made me a convert
-2. Kinda obvious, but: as a new tool, support in editors and other tools is much much lower

+1. I hope jj takes off because it exposes its repo model much better with its UI than git does, would have saved me the hours of time and effort and frustration before I got git's model.
-1. Having understood git's model now though, jj doesn't offer me as huge a benefit as it would've otherwise

jj init — Sympolymathesy, by Chris Krycho Jujutsu (`jj`) is a new version control system from a software developer at Google. I have been using it full time for 6 months. Here’s why you should switch, too.

Ok, I tried out the jj (jujutsu) version control system, read through v5.chriskrycho.com/essays/jj-in... and worked my way through steveklabnik.github.io/jujutsu-tuto... . Writing down my thoughts here: ⬇️

It's the "non-following" part that seems bothersome to me. Updating the bookmark manually seems like an extra bit of busywork to do before every push, for not much gain.

But I'll try it out and see how it actually feels in practice, I'm partway through Steve Klabnik's jj tutorial now.

Point 2 is a common, frustrating hurdle for new tools to overcome:

"I'm aware old tool Jank has holes and rocky bits, but I've used duck tape and add-on tools to make it work well for me. Now any new tool Shiny has to be better than the whole - wonky, but working - system, not just Jank alone".

First impressions:

1. jj is a better tool than git CLI by itself

2. compared to my current git+aliases+lazygit workflow:
a. conflict handling maybe jj's biggest advantage
b. interop with forges maybe its biggest issue

3. anonymous non-following branches seem the weirdest bit, but weird ≠ bad

You should learn #JuliaLang because it’s fun

@steamdb.info please add a Storage Space criterion to the Search page! that's one of the first things I wanna filter on these days, given that every game wants to take up 20+ GB of space!

Happy New Year and all the very best for 2025! I hope it will be a year full of health, happiness, beauty and playfulness for you! 🎉🥂🍾✨🥳😊

New Year celebrations are great and all, but it's when you press a hotkey to enter today's date and see "Jan 1, 2025" that it hits you, that you really are in a new year!

45^2 = (9 * 10 / 2)^2 (Given): (n * (n + 1) / 2)^2 = 1^3 + 2^3 + ... + n^3 (9 * 10 / 2)^2 = 1^3 + 2^3 + ... + 9^3

It quite possibly originated there; I'd imagine someone saw that and remembered the formula for the sum of cubes:
