I’m often asked to edit friends’ or coworkers’ writing, anything from emails to short stories to documentation. Recently, someone asked me how I edit. What am I looking for? How do I know what changes to make? That made me stop and think about what I’ve been doing semi-instinctually.

What I found in the mire
I made a graphical IRC client that runs in UEFI. It’s written in Rust and leverages the GUI toolkit and TrueType renderer that I wrote for axle’s userspace. I was able to develop it thanks to the vmnet network backend that I implemented for QEMU. You can connect to an IRC server, chat and read messages, all from the…

Preface In October 2023 I learned about HTTP/2 Rapid Reset attack, dubbed “the largest DDoS attack to date”. I didn’t have deep knowledge of HTTP/2 back then. I knew its basics like frames or HPACK but I was focusing more on HTTP/1.1 protocol and programming languages vulnerabilities. I decided to dedicate time to…

Credit card rewards are mostly funded out of interchange, a fee paid by businesses to accept cards.
The way that most physicists teach and talk about partial differential equations is horrible, and has surprisingly big costs for the typical understanding of the foundations of the field even among professionals. The chief victims are students of thermodynamics and analytical mechanics, and I've me
Was the ssh backdoor the only goal that "Jia Tan" was pursuing with their multi-year operation against xz?
The French news service contexte.com has today published the latest Belgian Presidency's proposal for introducing indiscriminate chat control scanning of private messages for illegal content.

I recently decided to make an app for the Apple Vision Pro (AVP) during a two-week break between jobs. I wanted to explore its potential and learn some new skills. My day job primarily involves low-level firmware; I hadn’t built a user-facing app in a while–my last iOS app experience was back in high school in 2011!…
Lars Wirzenius Consulting Ltd has created a Git repository with the source code of Debian 12 (bookworm), the main component. It's one repository for all the source code, as one commit. It's a monorepo .
Andres Freund published the existence of the xz attack on 2024-03-29 to the public oss-security@openwall mailing list. The day before, he alerted Debian security and the (private) distros@openwall list. In his mail, he says that he dug into this after “observing a few odd symptoms around liblzma (part of the xz…
Why do startups typically fail? It turns out that "avoiding those things" is already a plan for success.
Breakneck is the ultimate SaaS Starter Kit for .net developers. Lettings you focus on your business instead of boilerplate code.
Over a period of over two years, an attacker using the name “Jia Tan” worked as a diligent, effective contributor to the xz compression library, eventually being granted commit access and maintainership. Using that access, they installed a very subtle, carefully hidden backdoor into liblzma, a part of xz that also…
I have a lovely, and reasonably priced, Mini Panda Rice Cooker. It does not have any SmartHome features. You put in water and rice, press a button, it cooks rice. Nice! The only problem is - I don't know how long the rice will take to cook. It uses "Fuzzy Logic" to work out exactly how much heat and time is needed for…
