This month marks the publication of "The Actual Star," a new, wildly ambitious, wildly successful novel by Monica Byrne, spanning 3,000 years of history from the ancient Maya to a distant future.
A look into the tech and tools used by Winterbloom
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…
One of my favorite books is 2013 "High Performance Browser Networking" by Ilya Grigorik. Besides a wealth of actionable advice, the book is illustrated with captivating real life stories.

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's something happening in the E Ink space, somewhat quietly, but ...
Less than a month ago, I began investigating the Apple M1 GPU in hopes of developing a free and open-source driver. This week, I’ve reached a second milestone: drawing a triangle with my own open-source code. The vertex and fragment shaders are handwritten in machine code, and I interface with the hardware via the…
Intel is in much more danger than its profits suggest; the problems are a long time in the making, and the solution is to split up the company.
Apple’s latest line of Macs includes their in-house “M1” system-on-chip, featuring a custom GPU. This poses a problem for those of us in the Asahi Linux project who wish to run Linux on our devices, as this custom Apple GPU has neither public documentation nor open source drivers. Some speculate it might descend from…
It took a while, but I finally managed to create my own Game Boy cartridge. With WiFi! At this point, it can only demo a simple telnet-style communication and access Wikipedia articles, but I am confident that I will showcase more in the future. For now, the interesting and surprisingly tricky part is how the thing…
A few months ago, I found this Hacker News post about the AirGradient DIY Air Quality Monitor. I had already been considering buying an AirThings Wave Plus sensor to monitor my home's CO2 levels, but the high price and limited 'ownership' of the data coming from it turned me off. So I built two AirGradient DIY air…
After a few weeks of investigating the Apple M1 GPU in January, I was able to draw a triangle with my own open source code . Although I began dissecting the instruction set, the shaders there were specified as machine code. A real graphics driver needs a compiler from high-level shading languages (GLSL or Metal) to a…
By segregating macOS background tasks on Efficiency cores, M1 Macs can run user apps unfettered on their Performance cores. And that feels really fast.
SpaceX's Starlink internet service uses satellites in low-earth orbit to provide high-speed Internet to underserved parts of the world, especially places without easy access to cable or fiber. SpaceX's Starlink beta opened up in my area, so I installed Dishy—that's the nickname for the large white satellite dish…
TL;DR Modern disks are so fast that system performance bottleneck shifts to RAM access and CPU. With up to 64 cores, PCIe 4.0 and 8 memory channels, even a single-socket AMD ThreadRipper Pro workstation makes a hell of a powerful machine - if you do it right! Update 1: Since 2021, networks have gotten faster and now…
init7 recently announced that with their FTTH fiber offering Fiber7, they will now sell and connect you with 25 Gbit/s (Fiber7-X2) or 10 Gbit/s (Fiber7-X) fiber optics, if you want more than 1 Gbit/s. While this offer will only become available at my location late this year (or possibly later due to the supply chain…
I’d recently bought a new XPS13 7390 (non 2-in-1) laptop. I had bought the 8GB variant, how hard could it be to upgrade?

This post tells about my journey on fast-booting a Raspberry Pi 3 (RPI). In addition to that, some optimizations are discussed that can be applied to a Qt (QML) application. At the end, we will have a …
When researching construction, you invariably discover that any new or innovative idea has actually been tried over and over again, often stretching back decades.
This article summarizes some lower level aspect of how GPU executes. Although GPU programming is not that complicated when compared to CPU, it also doesn’t match to what hardware is doing exactly. The reason is that we can’t just program GPU without some API, which is an abstraction over its inner workings. Since few…
