I recently purchased the textbook “Aircraft Control and Simulation” by Brian L. Stevens, Frank L. Lewis, and Eric N. Johnson 1 . This book covers the control and simulation of aircraft. It’s really dense and frankly hard to understand. As far as aerodynamics texts go, it’s pretty typical.
Ever wondered how AI agents actually work behind the scenes?
This is not a C tutorial; there are plenty of those on the web. The reader is assumed to have some basic knowledge of programming in general, and preferrably the C programming language in particular. Maybe you just finished reading a tutorial somewhere, and you would like to learn some more about programming by…
Exploring the world of constraint solvers with very simple examples.
Is this clickbait? Not really. Is this the fault of the language or the compiler? Definitely not. Rather, it was part of a rushed migration. Sharing the lessons learned in the process.
AI can write code, but it can’t build real software. Software engineering remains human work because AI can code, not engineer.
One great question in office hours led me to delete a whole class.
The latest Go release, version 1.25, arrives in August 2025 , six months after Go 1.24 . Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before.

Side projects I have shipped, sold, or shut down, from modern.css to older WordPress experiments.
Large Language Models (LLMs) are typically presumed to process context uniformly—that is, the model should handle the 10,000th token just as reliably as the 100th. However, in practice, this assumption does not hold. We observe that model performance varies significantly as input length changes, even on simple tasks…
Claude Opus 4 and 4.1 can now end a rare subset of conversations. An update on our exploratory research on model welfare.
As we approach the 10 year anniversary of the 1.0 release of Kubernetes, let's take stock of the successes and failures of the project in the wild. Also what would be on a wish list for a Kubernetes 2.0 release.
GCC 15 brings better error messages and diagnostics for your code, including prettier execution paths and easier-to-read compiler errors for C++ templates.
Ever since moving to New York City, I've found my time to be in more demand than ever. Between work, meetups, and social events, I have noticeably less time for side projects than I had before moving here. At the same time, my commute is a massive time suck. It's 30 minutes each way, which doesn't sound that bad, but…
Tracing Rust AtomicU64::fetch_max from macro expansion and rustc intrinsics through LLVM atomicrmw umax down to the final x86-64 CAS loop.
Rust's borrowchecker comes with real downsides
Why Elixir is not just a good platform for modern development, but a great one - addressing common misconceptions
This Gradient Updates issue goes over the major changes that went into DeepSeek's most recent model.
I always told people memory is cheap, black magic is OK and efficiency doesn't matter, but I was wrong.
I recently attended the Goatmire Elixir Conf and one of the standout talks for me was Saša Jurić’s “Tell Me a Story” . It was an incredible presentation that combined theatrical storytelling with practical technical advice. Saša performed parts of his talk in character, turning technical topics into a compelling…
People do or do not use debuggers for a variety of reasons. For one thing, they are hard to setup in many codebases. Second, you can’t use them when your application is running on remote environments (such as kuberenetes). So, anecdotally, I have seen way more people using Print/ log.Debug compared to a debugger.
History of the evolution of my C compiler and operating system for transputer when I was age 16.
I want less Big Tech in my life. After years of dismissing Helix as too fringe and complicated, I've tried (and loved) it.
HTML and CSS
This last decade has seen an inundation of new JavaScript runtimes (and engines in equal measure), enabling us to run JavaScript in all manner of contexts...
For the past 7+ years, I've been conducting a programming interview that has been a true personal favorite of mine. It was passed down to me from good friends (Jeremy Kaplan and Carl Sverre, and it was the latter whom I believe invented it). This interview has probably been
# TLDR Datastar is a new hypermedia framework that makes building real-time web applications simpler and more efficient. It prioritizes server-side logic, uses “signals” for automatic UI updates, and leverages Server-Sent Events for lightning-fast performance. If you’re looking for a streamlined alternative to…
