Last year Richard Feldman gave a very neat talk at Strange Loop about using reference counting to find palces where a compiler for an immutable language can silently perform mutation for performance gains.
Nikolay Dubina has collected a "handy list of well-known and lesser-known tools for Go projects"
Raghu R wrote this tutorial for the k language, which I admire from afar. I aspire to go through this some day, but probably never will.
Jason Miller collected this list of "Application Holotypes", an attempt to roughly categorize types of applications and the architectures appropriate to them.
QP Hou created roapi, which "automatically spins up read-only APIs for static datasets without requiring you to write a single line of code." A very neat idea I don't have a direct use case for but I'll be looking for one.
I've known about rr before, but I was reminded of it this week. It's a debugger that enables you to record the events that occur in an application execution and replay them - a practical time travel debugger.
The supabase folks teamed up with "snaplet" to get postgresql running in the browser. The neatest part of this trick is that they used v86 to run a whole linux VM in WASM to do so.
A report from Jamie Brandon on his attempt to write a SQL parser in Zig in one week. Dan Luu asked on twitter what similar examples there are where somebody presents a project you can follow along with, which spanwed an interesting thread. I suggested a few examples, including Bitwise by Per Vognsen, which is criminally under-rated.
Via this video of Hania Rani playing a gorgeous, bizarre, vertical piano before it goes to Nils Frahm's studio, I discovered her lovely piano work. ht Tim Bray.
New King Gizzard album this week! I love this extremely prolific and genre-hopping Aussie band. The new album is mostly in a jam-rock groove, which is not normal for them, but not being normal is normal for them. I like this album more than anything they've released in the last few years.
