Magic Numbers
1500 bytes is a bit out there as numbers go, or at least it seems that way if you touch computers for a living. It’s not a power of two or anywhere close, it’s suspiciously base-ten-round, and computers don’t care all that much about base ten, so how did we get here?

Sysadmin friendly high speed Ethernet switching
I’ve been on the lookout for a ethernet switch that I don’t hate, the problem with a lot of higher speed (10G and above) ethernet switches is that they are quite expensive new and if you buy the used then they rarely have many years left ( or none at all ) of software patches.

The Performance Impact of C++'s `final` Keyword
If you're writing C++, there's a good reason (maybe...) as to why you are. And probably, that reason is performance. So often when reading about the language you'll find all sorts of " performance tips and tricks " or " do this instead because it's more efficient ". Sometimes you get a good explanation as to why you…

The problem with invariants is that they change over time
Cliff L. Biffle blogged a great write-up of a debugging odyssey at Oxide with the title Who killed the network switch? Here’s the bit that jumped out at me: At the time that code was written…

Project community server: https://discord.gg/side7 On September 20th, 2022, the live-service first-person hero shooter "GUNDAM EVOLUTION" was launched. A little over a year later, on November 29th, 2023, it abruptly reached its end of life. As a passionate enthusiast of hero shooters and the Gundam franchise, the…

Learning about distributed systems: where to start? (2020)
This is definitely not a "learn distributed systems in 21 days" post. I recommend a principled, from the foundations-up, studying of distrib...

Sandboxing all the things with Flatpak and BubbleBox
A few years ago, I have blogged about my approach to sandboxing less-trusted applications that I have to or want to run on my main machine. The approach has changed since then, so it is tim...

Why good external SSDs are faster with Apple Silicon
Why an Intel Mac’s up to 40 Gb/s from Thunderbolt 3 is less than an Apple silicon Mac’s up to 40 Gb/s from USB4, and how you can benefit from it.

OpenBSD is a cozy operating system
With the recent release of OpenBSD 7.5, I decided to run through my personal OpenBSD “installer” for laptop/desktop devices. The project is built off of the dwm tiling window manager and only installs a few basic packages. The last time I updated it was with the release of 7.3, so it’s been due for an minor rework.

The challenges of building modern open source software on PowerPC Mac OS X
PowerPC Macs were produced in huge numbers, and a lot of this hardware is still viable for use today, with professional software such as Photoshop CS2 and Propellerheads Reason. They're still good workstations, with lots of productivity software, and no always-online tracking or distractions. Originally, I got mine…

The simple beauty of XOR floating point compression
I recently implemented a small program to visualize the inner workings of a scheme that compresses floating point timeseries by XORing subsequent values. The resulting visualizations are quite neat…

How I tripped over the Debian weak keys vulnerability
Those of you who haven’t been in IT for far, far too long might not know that next month will be the 16th(!) anniversary of the disclosure of what was, at the time, a fairly earth-shattering revelation: that for about 18 months, the Debian OpenSSL package was generating entirely predictable private keys .

Distributed SQLite: Paradigm shift or hype?
SQLite is fast, really fast. On a single ~40€ / m commodity server, it can sustain ~168,000 reads and ~8000 writes per second, concurrently. Because it's an embedded library designed for client-side applications such as embedded systems and phone & desktop applications, SQLite databases have to be co-located…

Glory is only 11MB/sec away (2023)
One thing is certain in life: if you’re getting something for a steal, someone is getting screwed, and it’s probably you elsewhere. This isn’t an anti-capitalist rant, it’s just the truth. Companies don’t exist if they don’t make money. Unless there’s some innovation, rest assured that you’re overpaying somewhere else.

An IRC client in your motherboard
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…

HTTP/2 Continuation Flood: Technical Details
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…
