A few months back I gave a talk in which I shared a list of my personal engineering axioms – things that, over the years, I've come to think of as generally true and useful to have in mind when writing code, building things, and working with others.
Just over 2 years ago Microsoft open-sourced the entire .NET framework, this posts attempts to provide a ‘Hitchhikers Guide’ to the source-code found in the CoreCLR GitHub repository.

Recently I was doing some work decoding the new Galileo High Accuracy Service data. In short, this new service will allow Galileo (“European GPS”) users to achieve decimeter-level accuracy, which is nice. This “HAS” data is transmitted highly redundantly by making good use of Reed-Solomon encoding. To work with this…
Some clarification on what's going on with Redux
The Python community should fork Python 2.
Fixing common Java anti-patterns took an app from 1,198ms to 239ms. Eight patterns that compile fine and pass code review but silently drain CPU and balloon heap, with benchmarks and code fixes for each
This is the second in a series of posts I intend to write about how to build, deploy, and manage …
I sometimes get asked for recommendations of what programming language to "learn next". It's great that folks appreciate the fact that being exposed to several sufficiently different programming languages is an important step on the path to programming enlightenment. But it's also true that, given limited free time…
This is a guide for starting a TypeScript project in 2021 with modern tooling. TypeScript 4 Optionally esbuild to bundle for browsers (and Node.js) Linting with typescript-eslint (tslint is deprecated) Testing with Jest (and ts-jest) Publishing a package to npm Continuous integration (GitHub Actions / GitLab CI)…
To say my first foray into Rust was a frustrating struggle would be an understatement. I picked a terrible first project that left me neck deep in Rust’s trickiest areas right off the bat. I was excited to try again. A few years ago I wrote Sumoshell, a CLI App for log analysis. I’d wanted to improve it for a while…
Some new minor leap second drama is coming up, and for once we can
Reading how copy-paste works from the Wayland specification is non-trivial unless you understand a lot of how desktop computing works and Wayland internal. It took me quite a while to figure it all out, though once you get there, it seems quite obvious.
Many have observed that today's computers are distributed systems implementing the abstraction of the shared-memory multiprocessor. The wording in the title is from the 2009 paper " Your computer is already a distributed system. Why isn't your OS? ". Some points from that and other sources:

Exploration into providing MCPs with the most powerful of all tools: code.
You click a link in your chat app, your browser with a hundred tabs comes to the front and opens that page. How hard can it be? Well, you probably know by now that Wayland, unlike X, doesn’t let one application force its idiot wishes on everyone else. In order for an application to bring its window to the front, it…
I recently changed jobs and found myself in a position where I would need to do a lot of work on remote machines. Since I am Emacs user, the most common way to do this is using TRAMP (Transparent Remote access, Multiple Protcol). TRAMP is an Emacs package that let’s you treat a remote host like a local system, similar…
LLM-based agents can do a lot of tasks. Or, at least, they can appear to do them. For example, they write code, summarize papers, plan trips, and fill in forms. If you ask one for a probability or a confidence score, it will give you one of those too. I have seen many agent designers use LLMs to generate confidence…
This article describes a project of mine that has been laying around my harddrive in a rough draft for a couple of months. I want to continue developing it at some point, but can’t right now …
Unix counts time as seconds since the epoch. Seems straight forward. What could possibly go wrong?
DNS servers often have to convert DNS names to their canonical lower case form. BIND has to do so a bit more than most because it tries to preserve the case of DNS names rather than canonicalizing them.
How I wrote GoAWK, how I tested it, and how I measured and improved its performance.
