But I would like to write something personal about why I am doing this. What is the goal of building exe.dev ? I am already…

Introducing QOI — the Quite OK Image Format . It losslessly compresses RGB and RGBA images to a similar size of PNG, while offering a 20x-50x speedup in compression and 3x-4x speedup in decompression. All single-threaded, no SIMD. It's also stupidly simple .

The largest Git repo
It’s been 3 months since I first wrote about our efforts to scale Git to extremely large projects and teams with an effort we called “Git Virtual File System”. As a reminder, GVFS, together with a set of enhancements to Git, enables Git to scale to VERY large repos by virtualizing both the .git folder […]

24-core CPU and I can’t move my mouse
This story begins, as they so often do, when I noticed that my machine was behaving poorly. My Windows 10 work machine has 24 cores (48 hyper-threads) and they were 50% idle. It has 64 GB of RAM an…

Most PCs tend to boot from a primary media storage, be it a hard disk drive, or a solid-state drive, perhaps from a network, or – if all else fails – the USB stick or the boot DVD comes to the rescue… Fun, eh? Boring! Why don’t we try to boot from a record player for a change?

Unbricking a $2k bike with a $10 Raspberry Pi
A few years ago I splurged on an exercise bike. It’s a pretty expensive item imho, both in upfront and ongoing subscription costs. But I was able to justify it by riding it all the time so that per-ride it wasn’t that expensive. I’m happy to say this was a huge boon for my fitness and it was worth every penny.
