Applied Cryptography Engineering
Applied Cryptography taught two generations of developers what they know about crypto, and it is a dreadful instruction manual. The book to replace it with, and what you still have to learn after.

Constraint Solving with MiniZinc
This is part one of a two-part article. Part two is here. A while back somebody told me to check out MiniZinc. Eventually I did and really enjoyed it, so figured I’d write about it here. This is actually going to be a two part article. Right now we’re talking about what it is and how it works, and in the next post…

A very subtle bug (2010)
6.033, MIT’s class on computer systems, has as one of its catchphrases, “Complex systems fail for complex reasons”. As a class about designing and building complex systems, it’s a reminder that failure modes are subtle and often involve strange interactions between multiple parts of a system. In my own experience…

Practical Makefiles, by example
The purpose of this document is to explain how to write practical makefiles for your everyday hacks and projects. I want to illustrate, how easy it is to use make for building your programs, and doing so, dispel the notion that resorting to big clunky graphical IDEs, or makefile generators such as autotools or cmake…

Everything You Never Wanted to Know About Linker Script (2021)
Low level software usually has lots of .cc or .rs files. Even lower-level software, like your cryptography library, probably has .S containing assembly, my least favorite language for code review.

Scaffolded LLMs as natural language computers
Recently, LLM-based agents have been all the rage – with projects like AutoGPT showing how easy it is to wrap an LLM in a simple agentic loop and prompt it to achieve real-world tasks. More generally, we can think about the class of ‘scaffolded’ 1 LLM systems – which wrap...

How user groups made software reuse a reality
Before the widespread existence of software repositories like CPAN, NPM, and PyPI, developers seeking to reuse an existing algorithm or library of routines would either check books or journals for code, or, they just might post a classified ad:

80386 Memory Pipeline
The FPGA 386 core I've been building now boots DOS, runs applications like Norton Commander, and plays games like Doom. On DE10-Nano it currently runs at 75 MHz. With the core now far enough along to run real software, this seems like a good point to step back and look at one of the 80386's performance-critical…

Defining Statistical Models in Jax?
This is Bob. And I’d like to know the best way for us to code a bunch of models in JAX to use to evaluate parallel algorithms including normalizing flows. I’m going to dump out my current thinking, but I’m really hoping to get feedback from experts on the best way to do this without starting a flame war in the…
