In the past few years, CPUs have gotten really fast. Shockingly fast! Yet most people are stuck on previous generation mobile chips (whether by choice, or by their companies choice), at a huge detriment to their productivity. Meanwhile, AI coding subscriptions like Cursor are all the rage these days. I'll skip the…
About 5 months ago I made the decision to start self hosting my own S3 . I was working on AppGoblin’s SDK tracking of the top 100k Android and iOS apps so was wanting a lot of space, but for cheap.
We will explore how we can use an Android E-ink tablet (or any tablet) as a monitor for Linux computer
At RISC-V Summit North America 2025, Andrea Gallo, CEO RISC-V International, and Phil Wennblom, Chair of the ISO/IEC Joint Technical Committee (JTC 1)., announced that RISC-V International has been approved as a PAS Submitter by the ISO/IEC JTC1.
Apple introduced the upgraded Apple Vision Pro, featuring the powerful M5 chip, the Dual Knit Band, and innovative features with visionOS 26.
I bought a MacBook Air M2. As of writing, it's very affordable with the 16 GB RAM, 256 GB SSD, 13.6" model available for $750. As of writing, also Asahi Linux doesn't support anything newer than M2.
Get ready for blending on-the-go.

100x More Efficient than Arm?
I have been using a MacBook Pro M4 as my portable computer for the last half a year and wanted to share a few short impressions. As always, I am not a professional laptop reviewer, so in this article you won’t find benchmarks, just subjective thoughts!
Today, we are glad to announce that ESP32-C5 is now in mass production.
We have fried two Ryzen 9950X CPUs in a few months by running GMP tests and the GMP-based factoring program GMP-ECM . This is not expected, of course. In this page, we provide as much information as possible to help analysing the problem.

Claimed end-to-end privacy doesn’t fully conceal your rear-end data
Especially if you want it to work.
Recently I undertook a hobby project to recreate an IBM XT Personal Computer from the 1980s using a mix of authentic parts and modern technology. I had a clear goal in mind: I wanted to be able to …
Apparently shlx is a “medium latency” (3 cycles) instruction on Alder Lake. My disappointment is immeasurable, and my day is ruined.
The GPU in your computer is about 10 to 100 times more powerful than the CPU, depending on workload. For real-time graphics rendering and machine learning, you are enjoying that power, and doing those workloads on a CPU is not viable. Why aren’t we exploiting that power for other workloads? What prevents a GPU from…
The bizarre story of how taking flash photos could instantly crash the Raspberry Pi 2, the community detective work that solved it, and why this strange bug revealed fundamental flaws in modern chip design.
These are CubeSats. Satellites that are going to space—or at least, the ones I have here are prototypes. But these have one thing in common: they're all powered by either a Raspberry Pi, or a microcontroller. There are already Pis in space, like on Mark Rober's SatGus, on GASPACS, and the Astro Pis on the Space…

The Cinema Industry is using its own standards for creating and distributing movies in a secure way. The DCI (Digital Cinema Initiatives) specification defines everything from file formats and encryption to the projection systems itself.
Can LLMs control robots? We answer this by testing how good models are at passing the butter – or more generally, do delivery tasks in a household setting. State of the art models struggle, with the best model scoring 40% at Butter-Bench, compared to 95% for humans.
My smart bike company went bankrupt, so I added a physical button to turn the light on/off
