LLMs are not superhuman at reading and writing neural network weights
A recent paper argues that frontier LLMs can work with neural network weights directly. This seems superhuman, but it isn’t. The paper shows that GPT-6 Astra…

Python and the Real-time Web
I had interview for the Flask book recently and some questions were related to realtime functionality - how it works, how to integrate realtime portion with conventional WSGI applications, how to structure application code and so on.

Elixir Streams
I previously wrote about explicitness in Elixir. One of my favorite ways the language embraces explicitness is in its distinction between eager and lazy operations on collections. Any time you use the Enum module, you’re performing an eager operation. Your collection will be transformed/mapped/enumerated immediately…

Careful with that Buffer
Last week I was sorting through several sets of Microsoft C 5.1 disks from 1988 (more about that later). While I was comparing the disk images to see whether the disks were the same or not, despite different labels and part numbers, I did a double take when I realized that a file with random e-mail fragments was, in…

The Log: An Epic Software Engineering Article

8086 Microcode Browser
Since releasing 486Tang , I’ve been working on recreating the 8086 with a design that stays as faithful as possible to the original chip. That exploration naturally led me deep into the original 8086 microcode — extracted and disassembled by Andrew Jenner in 2020.

We shouldn't have needed lockfiles
Lockfiles are an absolutely unnecessary concept that complicates things without a good reason. Dependency managers can and are working without it just the same.

A bug story: data alignment on x86
This sounds unusual. Who ever wants to do this in real life? Normally, we only see code like this as primary school assignments or compiler benchmarks. However, this time it happened in real life.

Emacs users are like Terry Pratchett’s Igors
Within the constraints of the Emacs environment, there are no limits. Emacs is built upon this principle; the Lisp principle. Make some small kernel of features. A substrate. Take care to make this substrate programmable (in any language, Emacs chooses Lisp), and then build the system upon it. Let users worry about…

A million ways to die from a data race in Go
I have been writing production applications in Go for a few years now. I like some aspects of Go. One aspect I do not like is how easy it is to create data races in Go.

Go's Concurrency Examples in Java 19
There is no way for your operating system to know exactly how much stack space a thread will need so it allocates an amount on the order of around a kilobyte initially and then around a megabyte once the thread starts to be used. You only have around a bakers dozen gigabytes of RAM, so you can only have give or take…

Sync vs. Async Python: What Is the Difference?
Have you heard people say that async Python code is faster than "normal" (or sync) Python code? How can that be? In this article I'm going to try to explain what async is and how it differs from…

Optimizing compilers reload vector constants needlessly
Modern processors have powerful vector instructions which allow you to load several values at once, and operate (in one instruction) on all these values. Similarly, they allow you to have vector constants. Thus if you wanted to add some integer (say 10001) to all integers in a large array, you might first load a…
