PinePhone Misconceptions
I take no pleasure in writing this blog post. In fact, even as I am writing these words I am internally torn on whether this is the right approach to addressing the problem on hand. Whether I’ve chosen the right approach remains to be seen, but regardless, I now feel it’s time to confront misconceptions about the…

What is Electricity? (1996)
What is electricity? This question is impossible to answer because the word " Electricity " has several contradictory meanings. These different meanings are incompatible, and the contradictions confuse everyone. If you don't understand electricity, you're not alone. Even teachers, engineers, and scientists have a hard…

The CPUs of Spacecraft Computers in Space
Many CPUs have been used in space craft, space stations and other such probes. Such CPUs must be highly reliable, and very durable. The temperatures in space, even with heaters, can vary widely. The radiation that a system is exposed too can be immense. So when designing one of these systems designers don't always use…

Measuring keyboard-to-photon latency with a light sensor
For a long time when I’ve wanted to test the latency of computers and UIs I’ve used the Is It Snappy app with my iPhone’s high speed camera to count frames between when I press a key and when the screen changes. However the problem with that is it takes a while to find the exact frames you want, which is annoying when…

Coming soon: Fedora on Lenovo laptops
Today, I’m excited to share some big news with you—Fedora Workstation will be available on Lenovo ThinkPad laptops! Yes, I know, many of us already run a Fedora operating system on a Lenovo system, but this is different. You’ll soon be able to get Fedora pre-installed by selecting it as you customize your purchase…

8086 Microcode Disassembled
Recently I realised that, as part of his 8086 reverse-engineering series, Ken Shirriff had posted online a high resolution photograph of the 8086 die with the metal layer removed . This was something I have been looking for for some time, in order to extract and disassemble the 8086 microcode. I had previously found…

Pine64 announce the Pinecil, TS100 compatible RISC-V soldering iron
I cannot remember the last time I had this much to report. With so many announcements and highlights, I ran out of time and didn’t cover a handful of topics that happened this month. If I find the time, I’ll make a complimentary post later this month to cover the outstanding topics. Before we get into it, I’d also…

Programming with RISC-V Vector Instructions
Perhaps the most interesting part of the open RISC-V instruction set architecture (ISA) is the vector extension (RISC-V "V"). In contrast to the average single-instruction multipe-data (SIMD) instruction set, RISC-V vector instructions are vector length agnostic (VLA). Thus, a RISC-V "V" CPU is flexible in choosing a…

Adding a fiber link to my home network
Motivation Despite using a FTTH internet connection since 2014, aside from the one fiber uplink, I had always used network gear with 1 Gbit/s links over regular old rj45 cat5(e) cables. I liked the simplicity and uniformity of that setup, but decided it’s time to add at least one fiber connection, to get rid of a…

UASP makes Raspberry Pi 4 disk IO 50% faster
You can view a video related to this blog post here: Does UASP make the Raspberry Pi faster?. A couple weeks ago, I did some testing with my Raspberry Pi 4 and external USB SSD drives. I found a USB 3.0 SSD was ten times faster than the fastest microSD card I tested. In the comments on the video associated with that…
