We are sending out a proposal for Stacked Diffs on @GitHub to trusted design partners to gather initial feedback over the next few days. From there we’ll iterate and share the gameplan

@jaredpalmer21 Oct 2025
RE: Stacked Diffs on @GitHub After discussion w @ttaylorr_b, we can implement stacked PRs/PR groups already (in fact we kind of do with Copilot) but restacking (automatically fanning out changes from the bottom of the the stack upwards) would be wildly inefficient. To do it right, we need to migrate @GitHub to use git reftables instead of packed-refs so that multi-ref updates / restacking will be O(n) instead of ngmi. This will take some time but has been greenlit.

True! Successful drive by contribution :D

I just optimized the future of @ShopifyEng projects (& a lot more) for the next generation without being an intern/employee... I made a simple yet effective contribution to Ruby's core ZJIT compiler which had gotten merged. This allows array creations to go from N+1 calls to 1

Crazy - the new graph layout algorithm and viewer I made for SpiderMonkey is now being used for the ZJIT Ruby compiler: railsatscale.com/2025-11-19-… The thing was not meant to be general-purpose! But I'll take it.

Adding Iongraph support to ZJIT

ZJIT adds support for Iongraph, which offers a web-based, pass-by-pass viewer with a stable layout, better navigation, and quality-of-life features like labeled backedges and clickable operands.

When was the last time you checked your compiler (or JIT) output? I bet 99.999% of developers out there do not even know how to get to the compiler output in human readable form.

Anyway, this thread is getting too long. As you can tell I've nerd sniped myself on this whole topic. I'll tell you one more thing Both V8's and HotSpot's interpreters are known as "template interpreters" and I wrote a blog post on the whole damn topic: zackoverflow.dev/writing/tem…

Template Interpreters

A look at an under-discussed style of interpreter used by V8 and Hotspot.

This post has been sitting around in my drafts since March... I hope it has its intended effect bernsteinbear.com/blog/compi…

A catalog of side effects

Optimizing compilers like to keep track of each IR instruction’s effects. An instruction’s effects vary wildly from having no effects at all, to writing a specific variable, to completely unknown...

six months ago, the city threatened to charge me with a misdemeanor if I didn't remove this bench. I put the bench out because it's at the top of a very steep hill; dozens of people rest here every day. the original bench was seized but I now have a permit and new bench. 🥳
