In 2023, we launched an AI-powered Chief of Staff for engineering leaders—an assistant that unified information across team tools and tracked critical project developments. Within a year, we attrac...
In the context of out-of-order microarchitectures, I was under the impression that execution units remain occupied until the µop they’re processing is complete. This is often not the case.
An implemenation of the SuperMemo-2 algorithm.
In this tutorial, I will teach you how to write your own virtual machine (VM) that can run assembly language programs, such as my friend’s 2048 or my Roguelike . If you know how to program, but would like to gain a deeper understanding of what is going on inside a computer and better understand how programming…
Introduction The more I learn about Lua's design and implementation, the more impressed I am. It's very rare to see software that does so much with so lit...
The Ivory Tower is a blog about software engineering and development philosophy by Anders Sundman.
Grab your biggest mug of coffee and learn how the open-source programming language Rust supercharges our development time of the breakthrough Sonair 3D ultrasonic sensor. Claim to fame: Sonair is on track to be among the first to deploy a safety-certified Rust implementation.
This is not at all news, but it comes up often enough that I think there should be a concise explanation of the problem. People, myself included, like to say that POSIX time, also known as Unix time, is the number of seconds since the Unix epoch , which was 1970-01-01 at 00:00:00.
So I was working on improving a DOS emulator, when I found that something seemingly trivial wasn’t working right when COMMAND.COM was asked to do the following:
CPS, or continuation-passing style, is an intermediate representation for programs, particularly functional programs. It’s used in compilers for languages such as SML and Scheme. Much of its utility comes from its support for tail calls and nonlocal control flow such as call/cc, but it can also be used as an…
We are pleased to announce the release of Ruby 3.4.0. Ruby 3.4 adds it block parameter reference,changes Prism as default parser, adds Happy Eyeballs Version...
Design decisions core to JavaScript have caused a multitude of problems for benchmarking. Is there a solution to this?
On the concepts involved in a running program. What happens, exactly, when you double click an executable file, or launch it from the command line, and it begins to execute?
Where I try to explain why I feel like C\+\+ is so much fun, and to correct some misinformation.
A long time ago, I wrote a memoization library for Ruby. It was not easy, but I learned a great deal in the process. In this article, I am share these learnings and showing you how deep the memoization rabbit hole goes.
“The What and Why of Adapter based Parameter Efficient Fine Tuning: Understanding Its Purpose and Significance”
Now this summer school draws to a close, it seems appropriate to try to put its topic into some perspective

A few years ago, on a whim, I wrote YAIOUOM. YAOIOUM was a static analyzer for Rust that checked that the code was using units of measures correctly, e.g. a distance in meters is not a distance in centimeters, dividing meters by seconds gave you a value in m / s (aka m * s^-1). YAIOUOM was an example of a refinement…
We announced JMAP 10 years ago, here is an update on its progress
There are so many buzzwords and best practices out there, but let's focus on something more fundamental. What matters is the amount of confusion developers feel when going through the code.
The missing introduction.
Recently the Dutch Electoral Board (where I am also a very part time advisor) invited me to do a talk reflecting on their open source Abacus vote tabulation software. Much software is now provided as a service, and is typically deployed continuously (CD, continuous deployment), surrounded by enough automated testing…
I’ve been using Rust for hobby projects since 2016 and have been working professionally in Rust since 2021, so I tend to consider myself pretty knowledgeable about Rust. I’m already familiar with all the common limitations of Rust’s type system and how to work around them, so it’s pretty rare that I have to “fight the…
It is good practice to regularly inspect the statements running in the hot path of your Postgres instance. One way to do this is to examine the pg_stat_statements view , which shows various statistics about the SQL statements executed by the Postgres server.
This is the story of an investigation conducted by Jochen Sprickerhof, Helmut Grohne, and myself. It was true teamwork, and we would have not reached the bottom of the …

Trying to speedup my lexer using lookups and bitvectors but simd was just a step to far for me.
