It's quite common, in things like Kubernetes manifests, to use IEC-I size notations: Ki, Mi, Gi etc. This format is extremely accessible for humans, but if you're intending to programmatically extract and store them somewhere, you'll probably want to normalise them back to bytes. This snippet describes how to do that, with an example showing how to extract values from JSON with jq, convert them and then write the converted values back i..

grsecurity in Nixpkgs: an obituary (or: what was 'paxmark'?)

This post aims to provide a bunch of historical background around PaX and grsecurity support in Nixpkgs. It is fairly abstract and can probably be digested by non-Nix people with ease. This post is mostly focused on the implementation in Nixpkgs; I am not an expert in PaX/grsecurity (so if I’ve gotten something wrong, please correct me). I’m also partially writing this so that people know what paxmark was, in case they encounter a r..

A colleague of mine recently lent a hand implementing a polynomial approximation routine I could port to our compiler, though it wasn’t the method I was expecting. As I had written about previously, I was studying the Remez algorithm and implementing a prototype in Python. Remez approximation involves an iterated loop that alternates between root-finding and linear-system solving, and as such it can be rather brittle and difficult. Numerica..

Brent Miller: In April we would announce what we were doing for the conference in October... the year before Upscale we got zero done, which was just a terrible situation for us to be in. ...We started working on [Upscale] in the fall after the whiff on our conference, knowing we were going to roll it out in the spring—probably after we made the commitments for the fall—and we were going to have to do the organizational transformation....

It’s been nearly four years since I published Parsing Protobuf at 2+GB/s: How I Learned To Love Tail Calls in C . In that article, I presented a technique I co-developed for how to write really fast interpreters through the use of tail calls and the musttail attribute. While the article focused on Protocol Buffer parsers, the technique applies to many kinds of parsers and VM interpreters. I published the article in the hopes that the te....

Although first introduced in 2014, the Context package remains a crucial component of Go programming, enabling efficient management of request-scoped data, deadlines, and cancellation signals. As the Go ecosystem continues to evolve, understanding the Context package’s semantics is vital for developing reliable and maintainable software. This blogpost provides an in-depth exploration of the Context package’s semantics, highlighting best pra..

TL;DR : github.com/PriceChild/terraform-incus-oci-image-updating will update docker/oci images when applying. I deploy to Incus containers and take advantage of it's support for OCI (Docker) images to avoid running Docker as well. I deploy using tofu/terraform and the incus provider which seems to have a small drawback around keeping images updated.

This recent AI madness is insane. It feels like every hour, there's a new LLM, an AI model, a fork of AI, an AI tool, or an AI-supported website. The same applies to web development as well—there are tons of frameworks, libraries, tools, and other things I can’t even remember by heart. Every day, there's something new. How the hell are we, as humans, supposed to keep up with this pace? To be honest, I was really excited about these innova....

Today I attended a mini-hackathon via SDx. I attended to solo work on some arkaine agents and to be present as a mentor/advisory role for other attendees. It was a short 6 hour affair, mainly focused on playing with the new OpenAI o3-mini. It also helps to be inspired by seeing other people creatively applying AI to a quick weekend project. I ended up building a great prototype of a research agent - the original goal of arkaine for myself.

Unit testing is awesome . It helps you catch bugs early by ensuring all of the components of your program work as expected. Note: This guide is targeted towards experts who have advanced knowledge of ComputerCraft and know a few things about unit tests. Experience with unit tests in another language is helpful too, but isn’t required. CC: Tweaked contains a little-known unit testing framework called McFly , which describes itself..

I never used Twitter (I guess that’s the Zoomer side of the Zillenial in me), but since signing up for Bluesky, I’ve been pleasantly surprised with the quality of content. Their starter pack feature makes it easier than ever to get high quality posts delivered straight to your news feed. Also their “domain name as handle” feature is pretty nifty for those of us who feel it’s important to have their own space on the web. Plus you can ..

Most PG&E ratepayers don't understand how much higher the rates they pay are than what it actually costs PG&E to generate and transmit the electricity to their house. When I looked into this recently I was shocked. The average PG&E electricity charge now starts at 40 cents per kilowatt hour and goes up from there. […]

Back in 2020, when I worked in the supply chain side of Google, I had a fun and impactful side project related to human-level explanations of linear programs. A linear program is a mathematical model that defines some number of variables, linear constraints, and a linear objective function. When some variables are forced to be integer (ILPs), you can solve a lot of useful problems like scheduling, routing, and packing. That’s basically how ..
