Microwave ovens are curious beasts. A super convenient method of warming up certain foods, for boiling a cup of water, melting a little butter, or reheating frozen leftovers. But all too often, those frozen leftovers end up scorching in places and rock-hard frozen in others. Is this just random? Is it really the case…
TL;DR: An undocumented API in Google home devices is easily exploitable. This command will reboot any on your local network: nmap –open -p 8008 192.168.1.0/24 | awk ‘/is up/ {print up};…
How I went from buying a €200 tracker to building a custom telescope mount with harmonic drives, ESP32, and way more engineering than necessary
For the holidays, I decapped a chip that plays three Christmas melodies. The UM66T melody chip from the 1980s was designed for application...
An accelerated FAST feature detector for the ESP32-S3 leveraging 128-bit SIMD instructions, achieving ~2x the performance of the reference implementation.
These days, I’m building a lot of hardware projects based on the ubiquitous Raspberry Pi mini computer. Especially with the Raspberry Pi Zero W (an even tinier version, with the W denoting the wifi-capable version), you can have one anywhere and can power it from any USB power source.
A phone from Google that helps you get more done. It has everything you need in a phone, and a camera that you’ll love.
This is a reader question from “jlforrest” that seems worth answering in more detail than just a single sentence: I understand the need for a cache but I don’t understand why there are …
As harvest season begins here in the Midwest, I once again celebrate by grinding Nebraska gravel at the Gravel Worlds Long Voyage bike race. As in previous years ( 2021 ) ( 2022 ), I spent more time writing code for a marginally-useful project than I did training. But hey, I finished!
Apple today introduced an all-new iMac featuring an extraordinary design enabled by the M1 chip, and the best camera, mics, and speakers ever in a Mac.
As we head into another gifting season and more and more connected devices make their way onto gift guides, I want to offer a cautionary note. The smart home is like a cat — mostly self-sufficient and nice to have, but also possessing a mind of its own that can lead to frustration and confusion […]
Arm announces public filing of registration statement for proposed initial public offering
Our first generalist policy, π0, a prototype model that combines large-scale multi-task and multi-robot data collection with a new network architecture to enable the most capable and dexterous generalist robot policy to date.
When viewing LCD monitors from an oblique angle, it is not uncommon to witness a dramatic color shift. Occasionally, this can appear as a total color inversion. This is primarily caused by a polarization asymmetry, where light rays passing through the pixel matrix at oblique angles are influenced by the relative…

A blog about signals, programming, music, and other stuff.
I’m excited to announce that Google Cloud Platform (GCP) is the first cloud provider to offer the next generation Intel Xeon processor, codenamed Skylake.
I think the human race has no future if it doesn’t go to space. —— Stephen Hawking Starlink is a low Earth orbit (LEO) satellite internet service provided by SpaceX. Users connect to near-Earth orbit satellites through a user terminal, which then connects to the internet via ground gateways. Basic Starlink network…

What you may not know is that for years, the Mac also came with a death sound, that would play when the machine was unable to properly boot. And they are glorious: Macintosh II…
