In my video about the Raspberry Pi 5, I mentioned the new external PCIe port makes it possible to boot the standard Pi 5 model B directly off NVMe storage—an option which is much faster and more reliable than standard microSD storage (even with industrial-rated cards!). Enabling NVMe boot is pretty easy, you add a…
Why an Intel Mac’s up to 40 Gb/s from Thunderbolt 3 is less than an Apple silicon Mac’s up to 40 Gb/s from USB4, and how you can benefit from it.
Purism makes premium phones, laptops, mini PCs and servers running free software on PureOS. Purism products respect people's privacy and freedom while protecting their security.
What explains the popularity of terminals with 80×24 and 80×25 displays? A recent blog post " 80x25 " motivated me to investigate this. The ...
ARM64EC (and ARM64X) Explained Probably the most confused looks I get from other developers when I discuss Windows and ARM64 is when I used the term " ARM64EC ". They ask is the same thing as ARM64? Is it a different instruction set than ARM64? How can you tell if an application is or ARM64 ARM64EC?
DME (distance measuring equipment) is an aircraft radio navigation system that is used to measure the distance between an aircraft and a DME station on ground. DME is often colocated with a VOR station, in which case the VOR provides the bearing information. DME works by measuring the two-way time of flight of pulse…
mattst88's blog - Reverse Engineering the PROM for the SGI O2
If there’s one criticism I hear more often than any other about the pi, it’s “ I wish my Raspberry Pi had a floppy drive “. It’s really shocking that the pi doesn’t have the ubiquitous 34-pin floppy header that we all know and love. How else are you supposed to interface your Tandon TM100-2A or your Teac FD-55BR or…
SSE and SSE2 are available in every single x86-family CPU with 64-bit support. You too can play around with SIMD, which is great fun! Unfortunately, SSE2 level in particular also happens to be what…
I recently tried using the Minisforum DEG1 GPU Dock with a Raspberry Pi 500+, using an M.2 to OCuLink adapter, and this chenyang SFF-8611 Cable. After figuring out there's a power button on the DEG1 (which needs to be turned on), and after fiddling around with the switches on the PCB (hidden under the large metal…
In this blog post, I reverse-engineer a hybrid module that was used for ground-testing of equipment from the Apollo space program. But fir...
A wifi-deploying tank robot controlled with JavaScript/Node.js.
A few days ago, I wrote about how I'm helping restore a Xerox Alto for Y Combinator. This new post describes the first day of restoration...
Capacitor vendors don't want you to know this! Save money on capacitors by spending more on other components
Pushing affordable marine conservation forward with autonomous marine robots powered by Raspberry Pi Compute Module 4.
Sometimes people ask me: “Nicole, how do you convert a Master System game to the NES?”, or some other combination of game consoles. And the answer is invaria...
About a eight weeks ago I had virtually no interest in calculators. Blank, dull, tedious-looking objects that remind me of long, arduous rainy afternoons in 1980’s/1990’s school maths classes.
The future is here: LinHT booted up successfully for the first time. We believe that Software Defined Transceivers will be the next big trend in amateur radio.
Intel Core Ultra 200V series processors offer outstanding AI performance, compatibility and power efficiency at scale to leading laptop manufacturers.
I bought a Pinebook Pro in the first batch, and have been using it on and off for several months now. Some people I know wanted to know if ...

I edit videos non-stop nowadays. In a former life, I had a 2 TB backup volume and that stored my entire digital life—all my photos, family video clips, and every bit of code and text I'd ever written. Video is a different beast, entirely. Every minute of 4K ProRes LT footage (which is a very lightweight format…
We rarely, if ever, make responses to blog posts or articles. In fact, there is only one instance that I can think of when we did so. So then, somewhat uncharacteristically, this is a response post to Martijn Braam’s blog in which he explains why he left the PINE64 community. Let’s get one thing out of the way first…
You Tube is clearly used by a very large number of people. In general, they will be interested in watching videos of various types of content. One specific purpose is that it gets used to distribute, and make people aware of, audio recordings. A conversation on the “Pink Fish” webforum devoted to music and audio set…
What offers the convenience of a cassette tape, and the sound quality of a CD? Digital Audio Tape (DAT) does. So why wasn’t it more successful?
The Arduino Uno Q is... a weird board. It's the first product born out of Qualcomm's buyout of Arduino. It's like if you married an Intel CPU, and a Raspberry Pi RP2040 microcontroller—oh wait, Radxa's X4 did that. Arduino even tried it before with their old Yún board, which had Linux running on a MIPS CPU, married to…
