Electric cars are fantastic compared to ICE vehicles, but E-Bikes are even better. Much lower environmental impact and far more suited to medium range travel such as commuting. Here in NL they sell in huge numbers, far faster than electric cars. But they also have their limitations: a regular e-bike tops out at 25…

New 10 GbE USB adapters are cooler, smaller, cheaper
For years, the best way to get 10 gigabit networking on laptops was to buy an expensive, large, and hot 10 GbE Thunderbolt adapter. With new RTL8159-based 10G USB 3.2 adapters coming onto the market, the bulky adapters might be a thing of the past. Just look at the size of the thing in comparison to my Thunderbolt…

Why Skylake CPUs Are Sometimes 50% Slower
I got a call that on newer hardware some performance regression tests have become slower. Not a big deal. Usually it is a bad configuration somewhere in Windows or some BIOS settings were set to no…

Weird monitor bugs people sent me in the last 5 years
I develop 🌕 Lunar, a macOS app for getting intelligent adaptive brightness on external monitors and controlling every aspect of your monitor using DDC and other obscure protocols. I get tons of email about Lunar, especially after it became my full time “job” in 2021. A lot of those emails complain about Lunar bugs…

A Guide to Recording 660FPS Video on a $6 Raspberry Pi Camera
This article will discuss the setup steps that are required for recording videos at high frame rates on cheap Raspberry Pi cameras. Frame rates up to 660FPS on the V1 camera and up to 1007 on the V2 camera can be achieved. Filming at these extremely high frame rates on a Raspberry Pi is much more challenging and…
