I want the extended-nonce 256-bit reduced-rounds XAES-256-GCM/11 AEAD. It has infinitely randomizable nonces, a comfortable margin of multi-user security, and nearly the same performance as AES-128-GCM. Only issue is that it doesn’t exist.

The history, facts, and opinions.
Two universal facts about user documentation: Documentation is really important. We are really bad at writing it. We don’t have good theories on what makes for useful documentation. That is except for the four document model, or Diátaxis.1 I’m glad that people use it. I’m also a little frustrated that people use it…
Over the last several years, I’ve rewritten Rust’s regex crate to enable better internal composition, and to make it easier to add optimizations while maintaining correctness. In the course of this rewrite I created a new crate, regex-automata , which exposes much of the regex crate internals as their own APIs for…
Dynamicland is still going, just quietly. We closed the Oakland space for covid, but Realtalk development and collaborations have continued -- basically as originally planned, if more slowly due to our small size.
Designing a language, types first
A simple toolchain that Koding Kitty uses for building its web.
Relational (inner) joins are really common in the world of databases, and one weird thing about them is that it seems like everyone has a different idea of what they are. In this post I’ve aggregated a bunch of different definitions, ways of thinking about them, and ways of implementing them that will hopefully be…
What are the problems of C, and how Zig addresses them?
(This is a section of the lilos intro guide that people seemed to like, so to increase its visibility, I’m lifting it up into its own post and expanding it a bit. I hope this is a useful companion piece to the post on async debugging I posted this morning.))
What's inside that package.json? Pain.
I thought it would be fun to go outside of my comfort zone of web development topics and write about something completely different and new, something I have never written about before. So today, I'm…
In software, it is common to represent time as a time-stamp string. It is usually specified by a time format string. Some standards use the format %Y%m%d%H%M%S meaning that we print the year, the month, the day, the hours, the minutes and the seconds. The current time as I write this blog post would be … Continue…
This is an introduction to data structure flattening, a special case of arena allocation that is a good fit for programming language implementations. We build a simple interpreter twice, the normal way and the flat way, and show that some fairly mechanical code changes can give you a 2.4× speedup.
For a while now I've been trying to find a good way to explain what structured concurrency is, and how it applies to Rust. I've come up with zingers such as: "Structured concurrency is structured programming as applied to concurrent control-flow primitives" . But that requires me to start explaining what structured…
How to stand out in job interviews as an engineer.
2024-07-06 I’ve archived this post Looking for the post Racket frustrates me? You can read the original post on The Internet Archive’s Wayback Machine. Why archive this post? It’s been about a year since I published this post and since realized something: I don’t have any skin in the game anymore. My workflow is now…
I examine the somewhat surprising way how Linux handles writes.
Wolfram's Version 13.3 includes a subsystem around LLMs plus new functionality in integrals, special functions, finite fields, computational geometry, live highlighting in visualizations, AR & VR deployment. See examples for those and dozens of other enhancements.
Structures allow us to combine several variables to create a new data type. Some other languages support the same concept but call it “records”. If you come from object-oriented program…
I offer a high-level model for why software work feels like it sucks now: we don't treat software like creative output.
A series of patterns for building an AI co-pilot application.
You should give it a try!
Seth Michael Larson pointed out that the Python gzip module can be used as a CLI tool like this:
As a physicist, I’ve learned that the presence of 2 π 2\pi 2 π [▼] [ Or rather τ \tau τ , as it should actually be called . ] in a formula usually spells trouble. It’s kind of annoying to write by hand, easy to forget, and it’s dimensionless, so you can’t easily check if you forgot to divide or multiply by it…

In March 2018, I had been a full-time indie game developer for four years. My heroes were Jonathan Blow, Lucas Pope, and Robyn and Rand Miller. I had 2,500 Twitter followers, an ambitious title under my belt with thousands of sales, and a free office in a hip coworking space near downtown Columbus, generously provided…
