A few days ago I wrote about Rewind VM, a deterministic VM where every run of a Nix build is a pure function of its inputs, thread schedule included! I have been using it to find, reproduce and solve numerous race conditions in Nix builds, but it’s been making me feel a little crazy. What is this superpower, and why…
On my journey to learn CUDA, I decided to tackle the One Billion Row Challenge with it.
A while back there was a thread on one of our company mailing lists about SSH quoting, and I posted a long answer to it. Since then a few people have asked me questions that caused me to reach for it, so I thought it might be helpful if I …
Serverless means it's secure, right?
I built a small proof-of-concept for a system that enables real-time bidirectional editing between any modern code editor and a GUI, enabled by an LSP1 server. Code-based CAD I like working on small projects at home that benefit from CAD. I’m also a programmer with a personal development environment that I’ve spent…
I wrote a book. It’s called Janet for Mortals, and it’s free, and it’s on the internet, and you can read it right now. And you should read it right now, instead of reading this blog post, because this blog post is not very interesting if you haven’t read the book. Heck, this blog post is not very interesting even if…

I show how I improved four of my shell workflows to parameter-less commands with the help of fzf.
Note (version) : I wrote this originally as a Redis module in early 2014, then Redis included a modified version directly into official Redis releases in 2016. Note (implementation) : The implementation included with Redis 3.2+ changed some parameter orderings from my original (intentional, well-thought-out) design…

The reaction to the new table partitioning feature in PostgreSQL 10 has been overwhelmingly positive, but a number of people have already as...
This is the second post in a series. Read part 1 here.
Almost every one of you must have written a program, compiled it and then ran it to see the fruits of your hard labour. It feels good to finally see your program working, isn’t it? But to make all of this work, we have someone else to thankful too. And that is your compiler (of course, assuming that you are working in…
I first started using Python in 1993. It's been my main programming language since about 2000. I've written a ton of code in Python, both for work and in my free time. For several years now, I've been growing dissatisfied with it. Partly it's because I'd like more help from my programming tools, such as static type…
There has been much discussion of using the Rust language in the Linux kernel (for example, here , here , and here ), at the Kangrejos Rust for Linux Workshop ( here , here , and here ) and 2021 Linux Plumbers Conference had a number of sessions on this topic, as did Maintainers Summit . At least…
After 7 years in production, Scarf has reluctantly moved away from Haskell — Avi Press
I have started code reading groups at the last two companies I’ve worked at, Etsy and Twitter, and some folks have asked for my advice about code reading and running code reading groups. Tl;dr: don’t start a code reading group. What you should start instead I’ll get to in a moment but first I need to explain how I…
This is a psuedo-transcript for a talk given at Deconstruct 2019. To make this accessible for people on slow connections as well as people using screen readers, the slides have been replaced by in-line text (the talk has ~120 slides; at an average of 20 kB per slide, that's 2.4 MB. If you think that's trivial…
The LISP curse is often quoted as the reason why so few libraries and reusable components exist for LISP dialects. According to the concept, LISP is so power...
Free yourself from the chains of jQuery by embracing and understanding the modern Web API and discovering various directed libraries to help you fill in the gaps.
