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…
Announcing the successor to the groundbreaking Raspberry Pi Zero: the $15 Raspberry Pi Zero 2 W, built around our own RP3A0 System-in-Package
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…

Apple AirTags: Arbitrary data can be uploaded from non-internet-connected devices by sending Find My BLE broadcasts to nearby Apple devices. We're releasing an ESP32 firmware that turns the microcontroller into an (upload only) modem, and a macOS application to retrieve, decode and display the uploaded data.
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.
A blog by and for database architects.
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...
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…

Hydroponic farming is a method of growing crops without soil, with the main benefits of environmental and nutrient control, water conservation, and reduction of labor. This technique relies on a number of technologies that the principles of automation can be applied in order to improve yield and consistency. In this…
Broadband services are a wonderful innovation of our time, using multiple frequency bands (hence the name) to carry signals over wires (us...
I’ve always been attracted to chording keyboards in theory, but I lack whatever childhood musical training is required to wrap my fingers around them. So I made something else: an arpeggio keyboard. Peggi is an eight-key keyboard that fits on the back of your phone. While chording keyboards require you to press…
