Implementing neural networks on the "3 cent" 8-bit microcontroller
Bouyed by the surprisingly good performance of neural networks with quantization aware training on the CH32V003, I wondered how far this can be pushed. How much can we compress a neural network whi…

My 2023 all-flash ZFS NAS (Network Storage) build
For over 10 years now, I run two self-built NAS (Network Storage) devices which serve media (currently via Jellyfin) and run daily backups of all my PCs and servers. In this article, I describe my goals, which hardware I picked for my new build (and why) and how I set it up.

Is the keyboard faster than the mouse?
Which is faster, keyboard or mouse? A large number of programmers believe that the keyboard is faster for all (programming-related) tasks. However, there are a few widely cited webpages on AskTog which claim that Apple studies show that using the mouse is faster than using the keyboard for everything and that people…

It's dire: Raspberry Pi availability tracker
Yesterday André Costa emailed me about his new website, rpilocator. It's a website to track Raspberry Pi 4 model B, Compute Module 4, Pi Zero 2 W, and Pico availability across multiple retailers in different countries. In his own words: This database was created out of frustration trying to locate a Raspberry Pi…

Everything I've learned building the fastest Arm desktop
This is the fastest Arm desktop in the world, yes, even faster than the M2 Ultra Mac Pro. And today, I made it even faster. I upgraded everything: Faster RAM, 128 core CPU, 40 series GPU, I did it all, and we'll see how much we can obliterate the M2 Mac Pro. 128 cores—that's five times more cores, I'm also going to…

Exploring a Modern SMTPE 2110 Broadcast Truck
In October, my Dad and I got to go behind the scenes at two St. Louis Blues (NHL hockey) games, and observe the massive team effort involved in putting together a modern digital sports broadcast. I wanted to explore the timing and digital side of a modern SMPTE 2110 mobile unit, and my Dad has been involved in studio…
