You are seeing this because the administrator of this website has set up Anubis to protect the server against the scourge of AI companies aggressively scraping websites . This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.
An attempt to document my experiences and rationale for wanting to use a PinePhone, as well as my thoughts on mobile Linux in general.
If AM radio antennas were as long as a quarter wavelength of the carrier signal, you'd need an antenna as long as a football field.
Experimenting with ultrasonic data transmission in JavaScript as a payment method.
Video Appetizer TLDR I built a shortwave radio receiver from scratch using only cheap and easily available components, i.e. standard transistors, op-amps and 74xx logic chips. No typical radio part…
In this article, I share a beginner friendly guide to learning the basics of embedded systems and how they work. I talk about micontrollers, electronics, and software. I also share my motivation for working on embedded systems.
The first nerdy dispatch from my Quixotic Hardware Project, QIXOTE-1

When I discovered Google Fi six months ago, I thought to myself, “Finally, a phone service that accomplishes everything I need at a…
Fans, an active cooling element, move air in a system. Heat must be removed from the site of its production, and from the system as a whole. A fan increases heat convection with surrounding air via airflow. Air is at its highest pressure immediately in front of the fan, and at lowest pressure immediately behind it.
The internet is littered with explanations of how transistors work. Most of them don't really explain anything.
My fascination with PCMCIA cards was created out of “necessity”. Most of my retro computing interest revolves around networking, and I wanted something that could natively attach to modern Wifi networks without the need to maintain an old linksys router just for my retro computers. There are many ways to do this, I…
This little ARM64 single-board computer dragged me into the world of device trees, voltage regulators, and one of the worst Heisenbugs I encountered so far.
Last week Microsoft started selling their $599 Windows Dev Kit 2023, formerly known as 'Project Volterra'. I got my hands on one after a little bit of a shipping delay, and promptly started tearing it down to see what's inside. You can click here to browse the entire Twitter thread where I posted pictures of the box…
For over a year now, I use a Raspberry Pi 4 (with 8GB of RAM) as my daily desktop computer. I browse the internet, read and send e-mails, program software, edit photos, create images, watch Youtube videos and play games on it. Without any significant problems.
This is Part 6 over 6 of "Coding for SSDs". For other parts and sections, you can refer to the Table to Contents. This is a series of articles that I wrote to share what I learned while documenting myself on SSDs, and on how to make code perform well on SSDs. In this part,
DEFLATE is a relatively slow compression algorithm from 1991, which (along with its wrapper format, zlib) is incredibly widely used, for example in the PNG, Zip and Gzip file formats and the HTTP, …
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 tested over 20 microSD cards on every Raspberry Pi model to help you find the fastest one for your Raspberry Pi Single Board Computer
Millions of U.S. government employees and contractors have been issued a secure smart ID card that enables physical access to buildings and controlled spaces, and provides access to government computer networks and systems at the cardholder’s appropriate security level. But many government employees aren’t issued an…
Chips are the clearest example that economic efficiencies will not be the ultimate decider of technology’s end state: politics will play an important role.
Here’s a not-so-brief story about troubleshooting a problem that was at times vexing, impossible, incredibly challenging, frustrating, and all around just a terrible time with the bare-metal STM32G4 firmware for the moteus brushless motor controller. Background First, some things for context: moteus has a variety of…
Pop quiz: what classic brand of laptop is this? I'll give you another hint. Bright-red TrackPoint and mouse button trim, classic keybo...
Freshly whipped WebGPU, with ice cream
When running some tasks confined to E cores, the original M1 chip from 2020 completes them significantly quicker than an on an M1 Pro. Here’s the detail.
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.
I'll never forget when I bought the first 5K Retina iMac. Almost as soon as I ripped it out of the box, I booted it while holding down Command-F2, assuming it…
I was pleasantly surprised by how easy it was to make it possible to push a PC’s power button remotely via MQTT by wiring up an ESP32 microcontroller, a MOSFET, a resistor, and a few jumper wires. While a commercial solution like IPMI offers many more features like remote serial, or remote image mounting, this DIY…
