Counterfeits CPU were very common in the mid-90s. The worst period was between 1993 (just after the launch of the Intel 486 DX2) and 1998 (when the Pentium II started to be multiplier-locked). It was extremely easy for tricksters to remove the original marking and reprint another one with a higher f
Make your car electric for 5k in less than a day. A new motor and a new approach to convering cars to hybrid electric.
I recently came home to visit with family, but right now as I write this, it's 1:00am and I'm running memtest86+ by myself in the basement.
This post is about building an FPGA based networked key-value-store in the functional hardware description language Clash. I’ll describe my FPGA-tailored hashtable design, the testing framework I built for it, and its performance and resource usage.
With the end of Google's Stadia platform on January 18, 2023, Google published a website allowing people to "Switch the Stadia Controller ...
One of the most interesting navigation instruments onboard Soyuz spacecraft was the Globus INK, 1 which used a rotating globe to indicate...
In my last post , I figured out how to use Apple’s leaked Flasher utility from the 1990s to reflash a ROM SIMM inside of my Performa 630. It’s basically the Mac equivalent of a BIOS update, but only for Apple’s developers. The research involved in that post was quite a journey of reverse engineering from both a…
The Nano ESP32 introduces a new microcontroller architecture to the Nano family. The Nano ESP32 embraces one of the favorite IoT standards.
The price of Solid-state drives (SSDs) has dropped significantly over the last few years. It's now possible to buy a 1TB solid-state drive for less than €60. However, at such low price points, there is a catch.

A lot of people have asked about the computers I used to train TorToiSe. I’ve been meaning to snap some pictures, but it’s never “convenient” to turn these servers off so I keep procrastinating. We had some severe thunderstorms today here i

Intel introduced the 8086 microprocessor in 1978. This processor ended up being hugely influential, setting the path for the x86 architec...
Due to capital constraints, we are unable to meet our delivery deadline by EOY 2023 for Simula One preorders, and are pushing our optimistic shipdate to Q2 2024 (with a pessimistic ship date of Q4 2024 ). In this post we discuss our capital situation, mistakes we made, Review Unit testimonials, & investor feedback.
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
Two systems I know pretty well, Apache BookKeeper and Apache Kafka, were designed in the era of the spinning disk, the hard-drive or HDD. Hard-drives are good at sequential IO but not so good at random IO because of the relatively high seek times. No wonder then that both Kafka and BookKeeper were d
I made a custom split mechanical keyboard! Because it's me, this involved things like contributing to a PCB design tool and discovering a ridiculously optimized way to read a keyboard matrix.
Today I released a video about how—and why—I 3D Printed my Grandpa and put him on my bottle of ketchup. Watch it here. I sculpted a bust of my Grandpa in high school, gave it to my grandparents, got it back after he died and my Grandma moved out of her house (I wrote a tribute to my 'Grandpa Charlie'), and I kept on…
The updated MIDI 2.0 specifications have been released, so we're opening the repo to the public.

Cascade is a RISC-V CPU fuzzer that generates valid , long and complex programs, and relies on a termination cascade-effect for bug detection. It detected 37 new bugs (29 new CVEs) in 5 RISC-V CPUs, which is more than all the existing fuzzers, combined. You can read a paper we wrote on Cascade here and try it out here…
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.
In the Soyuz space missions, cosmonauts tracked their position above the Earth with a remarkable electromechanical device with a rotating ...
CT scans of counterfeit AirPods Pro and MagSafe chargers reveal pouch cell batteries in circular cavities, internal weights, and a fake ground pin.
In a new industry-standard benchmark, a cluster of 3,584 H100 GPUs at cloud service provider CoreWeave completed a massive GPT-3-based benchmark in just 11 minutes.
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…
Intel introduced the 8086 microprocessor in 1978, and its influence still remains through the popular x86 architecture. The 8086 was a fai...
