We demonstrate that it is possible to trigger Rowhammer bit flips on all DRAM devices today despite deployed mitigations on commodity off-the-shelf systems with little effort. This result has a significant impact on the system’s security as DRAM devices in the wild cannot easily be fixed, and previous work showed…
The Yamaha DX7 digital synthesizer was released in 1983 and became "one of the most important advances in the history of modern popular mu...
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…
The purpose of this article is to explain how to make a CPU out of rocks and sand as fast as possible without using too many words. As the world of proprietary hardware and software crushes in around us, we risk losing the ability to make things for ourselves as individuals. It is for this reason that I felt compelled…
There are longer tutorials on how to connect a USB printer to a Raspberry Pi and make it accessible via AirPrint but here's the minimal one ...

The ramblings and experiments of a software engineer and tech enthusiast based in Dublin.
Last year I started collecting ideas of things I would like to 3D print one day, on Twitter. Twitter is fundamentally ephemeral, so I'll collect it here instead. I got up to 14 items on Twitter, and now I'm up to 25.
The Soviet-made 1801VM2 CPU (a binary-compatible implementation of the PDP11 instruction set and QBUS interface) was developed in 1982. The 1801VM2 is a further development of the earlier 1801VM1 doubling the original 5MHz clock speed. From a constructive standpoint this CPU is a completely independent development.
The P cores in the M1 Pro/Max CPU are managed in two groups of four, sparing load on the second group, and distributing it unevenly within each group. Its two E cores outperform the four in the M1 …
A comprehensive guide to upgrading the Lenovo Thinkpad X230 with a better keyboard, a better screen and a custom coreboot BIOS.
CCC 5.1.27 and CCC 6 can make bootable copies of the system on Intel and Apple Silicon Macs (11.3+) right now, and we'll continue to support that functiona...

September 2021, the 11.7 Tesla MRI of the Iseult project, the most powerful in the world for human imaging, has just unveiled its first images.
Back in 2004, I visited a now bankrupt Dutch computer store called MyCom 1 , located at the Kinkerstraat in Amsterdam. I was there to buy a Western Digital Raptor model WD740, with 74 GB of capacity, running at 10,000 RPM.
I was wondering what would be the ultimate upgrade for my 386 motherboard. It has a soldered-in 386 CPU, an unpopulated 386 PGA socket, and a socket for either a 387 FPU or a 486 PGA. It might even be compatible with a Weitek processor, though I’m not entirely certain. There’s also a possibility that it has a…
The Raspberry Pi Zero 2 W has just been released, it's now got three more cores just like the RPi 3, but what is it good for and should you get one?
Announcing the successor to the groundbreaking Raspberry Pi Zero: the $15 Raspberry Pi Zero 2 W, built around our own RP3A0 System-in-Package
In this article, I document many of the most important changes that the KiCad developers have introduced to KiCad 6, including numerous "under the hood" improvements, and new productivity features in the front end.
