I’m not a POWER (or recently: Power) expert, only an enthusiastic user and advocate. Still, in the past couple of weeks a number of people from around the world asked my opinion how the POWER architecture could be kept relevant. This blog is really just an opinion, as I do not have the financial means to go ahead. It…
How I built a Sega Mega Drive dev kit from scratch: reverse engineering the cartridge slot, a homemade logic analyzer, a RAM cartridge and boot firmware.

Today, Arm announced that the first silicon supporting the Morello prototype architecture, a research project led by Arm, Microsoft, University of Cambridge and others, is now available on a limited run of demonstration boards, which are being shipped from today to industry partners for testing. Morello is the first…
It appears that Intel’s partnership with TSMC is much larger than it first seemed; the implications for Intel as whole are massive.
The RP2040 is a microcontroller chip designed by Raspberry Pi in the UK. It's a dual-core ARM Cortex M0+ running at 200 MHz which provides up to 16 MB of off-chip flash and 264 KB on-chip RAM. It has 30 GPIO pins, 4 of which can be used as analogue inputs, two UARTs, two SPI controllers, two I2C controllers, and 16…
We’ve been using a Sony Vaio VGN-P588E for the past few months as our primary personal laptop. This thing’s great; it’s got a small but not uncomfortable keyboard. It’s got a trackpoint, which we absolutely need to keep our hands healthy. Crucially, it’s only 1.5 pounds. We’re disabled in a way that means we’ve got to…
Rocket engines use a multitude of cooling concepts to keep them from melting themselves. Learn more about engine cooling in this article.
In 2004 I was working for Microsoft in the Xbox group, and a new console was being created. I got a copy of the detailed descriptions of the Xbox 360 CPU and I read it through multiple times and su…
A few months ago I stumbled on a tweet pointing out a kind of SFP optic that claimed to be smart, made by a Russian company Plumspace . After going through their Smart SFP product listings I was on-board and decided I needed to have some of them.
Regular readers would probably know that I have a love of batteries, and their associated test equipment. Maybe it was the fact that they were expensive, but pervasive, and my enjoyment as a child …
Sometime in 2024, the IEEE will unveil a new 802.11 standard that will bring new capabilities to everyone’s favorite wireless communication standard. But the upcoming 802.11bf standard isn’t for communication — it’s for sensing. The newest version of Wi-Fi layers on the ability to sense people or objects by using math…
How trying out new laptops and messing with my personal computing setup motivated me to go back to a laptop that some would call ancient.
I have always liked pinout diagrams like this: Arduino Nano Pinout. Source: http://www.pighixxx.com/test/wp-content/uploads/2014/11/nano.pngThey work quite well, there is all the information and they look nice. However, they work only when you have pins on two sides of the PCB and once you squeeze too much information…
I built my own laptop over the holiday break and it’s a developer’s dream come true. I took a chance and ordered a Framework Laptop DIY Edition. I’m so glad I did. The Framework is an excellent platform to customize and build a very capable and stable Linux machine for development. Here’s what I love about it and…

macOS manages the loading and frequency of M1 cores according to the QoS set, and rules which differ between the original M1 and the M1 Pro.
I've recently thought a lot about the essay The computer built to last 50 years by Ploum. It's a delightful piece about the author's ideal, long-lasting computational platform - precisely the thing I enjoy reading. It's got a nice blend of slow tech and libre computing advocacy mixed with personal ponderings centered…
Lately I'm paying more attention to the crypto currency and "DeFi" spaces, again. One discussion that comes up regularly: are miners to blame for the high GPU prices? To add some facts to this discussion, I’ve done a small analysis of GPU and crypto currency prices to determine if they are related.
The cell is the first to have been fully designed, developed and assembled at a gigafactory by a homegrown European battery company.
HP servers provide a management module called iLO (a.k.a. Integrated Lights-Out), which turns on as soon as the power cable is connected, loading a full-blown proprietary operating system. This module has full access to all the firmware, hardware, software, and operating system installed on the server. In addition to…
As 2021 draws to a close, we thought we'd take a look back at what's happened over the last year in Embedded Rust, both within the working group and in the larger community.
Just recently, there was a surge in traffic to my old legacy dial-up sounds pages. While I did my best with the equipment I had at the time to capture the sound of dial-up modems, I always knew tha…
The monitor story for Apple computers in [nearly] 2022 is basically would you like garbage, or would you like to take out a home equity loan?
I recently purchased a book for my MSC which was only available via a crappy Android app. There was no obvious way to decrypt it to read on a more sensible device, so I resorted to the ancient art of screenscraping. This is a quick-and-dirty way to grab images of the pages and convert them to a standard PDF using…
