What Hacker News says?
I would argue that the word "proof" in the title might be misleading you. From the post and the example he links, the point is that if you don't at least look at the running code, you don't know that it works. In my opinion the point is actually well illustrated by Chris's talk here: https://v5.chriskrycho.com/elsewhere/seeing-like-a-programme...

HN discussion> for me, everything git is a pain point Yeah, I was looking for something (or "things") specific. An "I hate everything about it" explanation doesn't really compel me to try out the alternative. > "megamerges" are one such example. ive shared many links, here and in other posts I read through one megamerge link you shared ( https://v5.chriskrycho.com/journal/jujutsu-megamerges-and-jj... ).

HN discussionYes. I have one repository, which is a fork of an OSS project, with a 7-way octopus merge of various patches I carry, and another 2-way merge on top of that one. Every week or two I pull the latest changes from upstream and I rebase all 9+ branches in a single command. If there are conflicts on any one of the parallel streams of work, I can trivially fix each conflict individually in any order I want. Jujutsu does n…

HN discussionhere's a few links that you might find useful. But it would be worth exploring the other recent hn discussions on the topic - i and other unabashed evangelists have shared a lot. A great "Megamerge" workflow https://v5.chriskrycho.com/journal/jujutsu-megamerges-and-jj... https://ofcr.se/jujutsu-merge-workflow And an absolutely fantastic TUI that wraps jj cli. Might be the best TUI ive ever used, and consistently get…

HN discussionhttps://v5.chriskrycho.com/essays/jj-init/ > The problems with Git are many, though. Most of all, its infamously terrible command line interface results in a terrible user experience. In my experience, very few working developers have a good mental model for Git. Instead, they have a handful of commands they have learned over the years: enough to get by, and little more. The common rejoinder is that developers ought…

HN discussionThis one is probably the best intro I've read: https://v5.chriskrycho.com/essays/jj-init/ Really, really good examples and walkthroughs with easy to understand, animated console sessions that show real-world-ish use cases including conflict resolution and why JJ's model makes it easier. Really good read and easy to digest because of the animated session replays. My main takeaway is that the missing pieces right now…

HN discussionI think you could achieve this with a variation of the "Working on Two Things at the Same Time" pattern[0], also explored more widely here[1] (with e.g. using private commits). Basically, just have a local-only merge-change that combines whatever you're working on, with all your local modifications. You can then even just create new changes on top of the `<dev>` change, and then rebase each into your branch when you…

HN discussionI’m curious, given salsa’s[1] so-far quite-effective use of the incremental computation (Adapton/Incremental/Bonsai), if you could elaborate on some of the pitfalls there for UI specifically. The primary salsa use case so far (in rust-analyzer[2]) is obviously fairly different from the pure UI use case, as it’s allowing other things to do the work on the UI and is using it purely for the incremental computation of c…

HN discussionA while ago I remember reading about this new VCS project Jujutsu (jj) that claimed to be both simpler and more powerful than git. A bold claim! Didn't really think much of it at the time beyond well this is interesting. But later, about 9 months ago, Chris Krycho published this lovely blog post[1] about jj and a thread about it was quite popular on HN. Again, really interesting, but not something I was going to dig…
