This computer was so good and so far out there, we didn't know what we had.
The first note in an independent robotics research project: a complete tabletop manipulation setup—industrial arm, two cameras, teleoperation, and a software stack built from scratch—for under €5,000.
The new processor is being developed to allow organizations to run Arm-native Linux environments simultaneously with z/OS and Linux on IBM Z, while benefiting from IBM’s established security, reliability, and scale.
I was very excited to get the latest version of my PCB from the manufacturer.
Apparently, one of my hobbies is making updates to my ergonomic setup, then blogging about it from an Amtrak train. I've gone and done it again.

In this piece, two researchers from PLA-affiliated National University of Defense Technology argue that Starlink will negatively impact global stability, in light of its clear military applications, increased risks of accidents and collisions in space, and SpaceX's close relationship with the U.S. military. The…

Putting iroh on a bare ESP32 to build a temperature-driven smart fan you can check on from anywhere.
Last time I wrote about profiling in Zig on Apple Silicon, I touched on PMU counter profiling. This time I decided to go further and create my own tool to fetch all available counters for Apple Silicon processors (M1, M2, and later). Brief explanation of PMU counters PMU (Performance Monitoring Unit) counters are…
We took the Duo all the way down to the gears, followed glowing dust into its hinge, and put its crease-hiding nano-texture under the microscope.
If hyperscalers and chip companies don’t build up a TSMC competitor they are set to forego billions of dollars in revenue and stunt the AI revolution.
Adventures with dry ice and RP2350 - how fast can it go?
I found my old reMarkable 2 paper tablet, bought in 2021, it had sat unused for ~4 years or so. The device was in a sorry state:
About a couple months ago I purchased an Arduino Nano ESP32 dev board. I had this sudden itch and I wanted to play around with hardware. I don't really have much experience in this space, besides working on firmware for an IoT company over a decade ago, but I've written tons of software over the years. I was very…
Modern hard drives store an incredible amount of data in a small space, and are still the default choice for high-capacity (though not highest-performance) storage. While hard drives have been around since the 1950s, the current 3.5″ form factor (actually 4″ wide) appeared in the early 1980s. Since then, the capacity…

Recently this post from @Merocle caught my eye: I'm fixing my iFixit soldering station. I haven't used it for a long time and the battery has gone overdischarge. I hope it will come back to life. Unfortunately, there are no replacements available for sale at the moment. Devices with built-in rechargeable batteries…
