White space does matter in C23
Usually in C identifiers are not directly followed by strings. But when U prefixed literals were introduced in C. there still were some rare clashes with existing code. This happened were a macro U…

Bringing Faster Exceptions to Rust
Three months ago, I wrote about why you might want to use panics for error handling. Even though it’s a catchy title, panics are hardly suited for this goal, even if you try to hack around with macros and libraries. The real star is the unwinding mechanism, which powers panics. This post is the first in a series…

Why Certificate Lifecycle Automation Matters
If you’ve perused the ActivityPub feed of certificates whose keys are known to be compromised , and clicked on the “Show More” button to see the name of the certificate issuer, you may have noticed that some issuers seem to come up again and again. This might make sense – after all, if a CA is issuing a large volume…

Well-Known Secrets of AmigaDOS
In keeping with the Commodore tradition of cost cutting, most consumer models of their Amiga line of computers came with severely watered down documentation. The Amiga 500 was an exception from this rule, but owners of later machines - such as the A1200 - may not have gotten any documentation for the command line part…

Bump Allocation: Up or Down?
Back in 2019, Nick Fitzgerald published always bump downwards, an article making the case that for bump allocators, bumping “down” (towards lower addresses) is better than bumping up. The biggest reasons for this are bumping up requires 3 branches vs 2 for bumping down and rounding down requires fewer instructions…

Pwned Certificates on the Fediverse
As well as the collection and distribution of compromised keys , the pwnedkeys project also matches those pwned keys against issued SSL certificates. I’m excited to announce that, as of the beginning of 2024, all matched certificates are now being published on the Fediverse , thanks to the botsin.space Mastodon server.

Thinking about high-quality human data
[Special thank you to Ian Kivlichan for many useful pointers (E.g. the 100+ year old Nature paper “Vox populi”) and nice feedback. 🙏 ] High-quality data is the fuel for modern data deep learning model training. Most of the task-specific labeled data comes from human annotation, such as classification task or RLHF…

"My boss says we don't need any engineering managers"

The Subprime AI Crisis
None of what I write in this newsletter is about sowing doubt or "hating," but a sober evaluation of where we are today and where we may end up on the current path. I believe that the artificial intelligence boom — which would be better described as a generative AI boom

Do we need to store all that telemetry?
In my last post I talked about why modern observability has become so expensive. At the end of the post I posit a question: What if by default we never send any telemetry at all? In this post I’m goin

Does anybody know this fractal? (2012)
Experimenting with the "divisibility" of complex numbers, I stumbled across this thingy. It looks like a fractal. Although the formula does not do any iterations. It reminds me of something. But I dont know what. Doing a Google image search brings up a couple of galaxies :) This image shows the region from (-1/-1) to…
