One cool thing about working on a web framework is that the tools you use to build a feature might eventually adopt the feature itself. 5.5 years later, in this case.

- Sorry for libbing out on here for the first time in a while, but Republicans in the Obama era were so unbelievably annoying, I would accept five consecutive woke 1s before going back to that for a momentJonathan Martin @jmartThe Cheesecake lunge is one part phantom limb stuff - 2026 version of Obama on price of arugula - and one part living off land’ism Until Obama teed up the that line, the most consistent and reliable messaging from Repubs was on the presence of good looking men2094.2K

- Posts @acdliteI love the weird squat dimensions of the outer screen. Instead of folding it into a chonky brick, I wish I could snap it in half and stick it back together.2011.1K

- Feature request for every agent harness: switch between the threads for me based on what most requires my attention. I'm tired of hunting for what to decide on next!190275.6K
- Posts @acdliteThe Projects feature in Claude Code is trending in this direction but in practice I still end up manually switching between threads constantly. But I can see the vision.1031.8K
- Posts @acdliteReordering the list is great but it's not enough, I want it to literally navigate to the thread without my intervention, like one of those DocuSign interfaces that zooms you to the next signature lineA. @antisymmetrics@acdlite t3 chat reorder the list. Is this the feature you are talking about? Or a shortcut that allows to switch/toggle between conversations?2041K
- I just discovered that v8's JIT doesn't inline Atomics. It uses the generic implementation every time. a[1] → 2 instructions Atomics.load(a, i) → ~130 (!!!) Brutal 😫 Anyone who can help me get this fixed? Happy (to have an agent) send a patch!7221127.7K
- A decade ago, after struggling on a hard problem in React Fiber, I spent several days designing and iterating on a fuzz tester that eventually uncovered a bunch of subtle cases that helped me converge on a solution. Today, a fuzz tester simply appeared in my codebase. Poof.13624817.5K
- Andrew ClarkRT @sjgoedecke: Working in large established codebases is one of the hardest things to learn as a software engineer. You can’t practice it beforehand (no, open source does not give you the same experience).060214
- You Can See Everything: The hype is justified. Just go see it fresh, don’t read any reviews that might spoil the experience. All I’ll say is I felt every minute of its 3 hour runtime, but when it was over I wished it would keep going.30549.7K
- Andrew ClarkRT @aurorascharff: Ahead of Next.js 16.4, I worked on applying the upcoming features across v0 and validating our new Partial Prefetching optimizer Skill in a real app. The post includes before-and-after videos of the navigation experience and walks through the caching, prefetching, and production checks behind the refactor. Excited to finally share it!Next.js @nextjsWe used a coding agent with Next.js 16.4's new prefetching controls and Skill to improve v0's navigation experience at no added cost. The loop: • Capture navigation with 𝚒𝚗𝚜𝚝𝚊𝚗𝚝() • Define the target UI in the test • Refactor until it passes070200

6816112.2K - I'm excited about <ViewTransition> in React but it's difficult for me to recommend because the web API has so many rough edges. E.g. scrolling during a transition is flat-out broken (and deemed a "wontfix" AFAICT) Any browser friends who can help?55718.6K
- Posts @acdliteTurns out scoped View Transitions will help, thanks for the reply @jaffathecakeAndrew Clark @acdlite@jaffathecake This improves the situation significantly, can't wait for that to ship more widely. Will integrate into React ASAP. Thanks!0081.4K
