This can useful when working with nested containers and wanting to reference an outer container in via container query units.30 Mar 2026 20:30 +0000at://did:plc:54rnras7c53rd2m7corycltf/app.bsky.feed.post/3micivqfntk2dhttps://bsky.app/profile/tfischbach.bsky.social/post/3mhyeqq74yc2vTIL if you want to split out multiple smaller changes from a larger one, you can use `jj split -r X -B X` to make sure the id of the remaining big change stays stable. #jj-vcs26 Mar 2026 19:49 +0000at://did:plc:54rnras7c53rd2m7corycltf/app.bsky.feed.post/3mhyeqq74yc2vhttps://bsky.app/profile/tfischbach.bsky.social/post/3mhvjwna2fk2zExperimenting with a custom jj-pin script to make history cleanup in #jj-vcs feel safer. I often find myself tweaking a stack of changes moving things around without wanting to change the overall diff. Especially when there are conflicts to resolve, I want to be sure not to mess up.25 Mar 2026 16:43 +0000at://did:plc:54rnras7c53rd2m7corycltf/app.bsky.feed.post/3mhvjwna2fk2zhttps://bsky.app/profile/tfischbach.bsky.social/post/3mch6sktrsc2jI really like the squash workflow in #jj-vcs. But what are people using to inspect the resulting change? Do you always type out `jj diff -r @-`?15 Jan 2026 08:41 +0000at://did:plc:54rnras7c53rd2m7corycltf/app.bsky.feed.post/3mch6sktrsc2jhttps://bsky.app/profile/tfischbach.bsky.social/post/3m7pbqgvubs2hThere's an interesting dynamic, where coding agents not only reduce the activation energy required to follow certain best practices (automated tests, small commits, limited scope etc.), but sort of turn them into prerequisites to have a chance of making the process work at all.11 Dec 2025 09:39 +0000at://did:plc:54rnras7c53rd2m7corycltf/app.bsky.feed.post/3m7pbqgvubs2hhttps://bsky.app/profile/tfischbach.bsky.social/post/3m2urpq4o5s27Current take on working with coding agents: Use them as an extra level of abstraction for the making, not for the made.10 Oct 2025 23:03 +0000at://did:plc:54rnras7c53rd2m7corycltf/app.bsky.feed.post/3m2urpq4o5s27https://bsky.app/profile/tfischbach.bsky.social/post/3m2to37enck2jNew favorite Emacs shortcut: C-c C-p to copy the current buffer's repo relative file path to clipboard prefixed with @ for easy pasting in Claude Code. https://github.com/tf/prelude/blob/1d909e44d0b149f96d4638b012cb80fb005f6259/personal/preload/copy-repo-realtive-path.el10 Oct 2025 12:25 +0000at://did:plc:54rnras7c53rd2m7corycltf/app.bsky.feed.post/3m2to37enck2jhttps://bsky.app/profile/tfischbach.bsky.social/post/3m2n32npzs22mMoreover, it seems to me that there is a third option beyond the “don’t look at the code” vibe coding approach and “big design up front” spec-driven development.
