Can I write a race detector in DTrace? For sure! gaultier.github.io/blog/detect_... #dtrace #golang #c

I wrote an article on how to write your own static site generator, and did not think it would interest many people, but someone posted it on lobsters and it got traction, so here goes! gaultier.github.io/blog/how_to_...

Did you know that in Rust, 'let _ = ...' and 'let _unused = ...' are NOT the same thing? I didn't until today! gaultier.github.io/blog/rust_un... #rust

I just implemented light mode/dark mode on my blog, using modern css features like variables and the ‘light-dark()’ function. Surprisingly easy, try it! gaultier.github.io/blog/ #css #blog

Tracking and fixing many Go data races lately, I am getting a new found understanding and empathy for all these Mozilla developers who jumped on Rust the moment it was halfway usable. Like a lost, thirsty traveler in the desert seeing an oasis from afar. #golang #rust

A million ways to die from a data race in Go. New blog post. Well it’s not quite a million, but still. gaultier.github.io/blog/a_milli... #golang

“Hell is other people”. Sartres clearly did not have to support 4 different SQL databases in the same codebase at scale. Lucky bastard.

The good thing about spending your Friday afternoon pulling your hair troubleshooting a bug, is that it makes for a nice blog article afterwards… gaultier.github.io/blog/subtle_... #bug #golang

I joined the Go team just after exploiting a carry bug in a Go assembly core, and I've been looking for ways to prevent the next one ever since. This year's attempt is very promising: mutation testing swapping e.g. ADC → ADD, CMOV → MOV, etc. to provide test coverage for constant time assembly.

Me: wow, my new work got me the new M4 MacBook Pro with 48 GB of RAM, every build is going to be instant! npm run build: Worker terminated due to reaching memory limit: JS heap out of memory. Tim Apple giveth, JavaScript taketh away

Modern webdev is so much. I'm installing so many packages and gems and I'm completely unsure of what is doing how and where. One day I'll have to get used to this stuff. It's very different from Systems Engineering.

... Well. I got a paper number, despite thinking I'd just hold onto it. No wording but I think it's about as complete as it can be. thephd.dev/_vendor/futu...

Me, after 10 years of coercing various crazy C & C++ build systems and mixed language codebases to work everywhere even on old unsupported BSDs: Unlimited power! I can do anything ! Me after 2 weeks of having to work with npm and the JavaScript world: I’m in danger.

I recently had the honor of interviewing Zen’s chief architect Mike Clark! I tried to fit in as many microarchitecture questions as I could, including x64 vs ARM ISA power efficiency, 4k vs larger page sizes, 64-byte cache lines, scatter/gather and more: www.computerenhance.com/p/an-intervi...
