We have a big announcement. Very big, in fact. Four times bigger than any previous announcement. We make Halide, a camera app that combines intuitive, polished design with the powerful features found in professional gear. Today we’re bringing Halide to a whole new form factor. Meet Halide for iPad!
Researchers demonstrate a solution to a 40-year problem
There are many good, modern solutions for reading data off old floppy discs and drives. Perhaps the best is the Greaseweazle : it's capable,...
By segregating macOS background tasks on Efficiency cores, M1 Macs can run user apps unfettered on their Performance cores. And that feels really fast.
I presented this project at BangBangCon West 2020, but never got around to publish a blog post about it. A 10 minute talk is not enough to cover some technical aspects, and since I’m starting to forget them, it’s about time to write things down.
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.
It’s bad out there for customers of electronic parts and components. The semiconductor shortage is so severe it’s being covered by mainstream media; meanwhile, various politicians have tasked their aides with looking at the global supply chain. Indeed, in the short term, the dearth of chips is already leading to…
Earlier today I did a livestream on my YouTube channel to attempt using an Nvidia GeForce GTX 1080 on a Raspberry Pi Compute Module 4. As with all my testing, I'm documenting everything I learn in this GitHub issue, which is part of the Raspberry Pi PCI Express Card Database website. It's only been a few hours, but…
aka: how I “accidentally” discovered what I already suspected: optimization methods are at the heart of landing rockets.
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.
Dmitry.GR: How to reverse engineer a completely undocumented microcontroller. From nothing to a full SDK in one week flat!
The American Radio Relay League (ARRL) is the national association for amateur radio, connecting hams around the U.S. with news, information and resources.
Here's how I built an ultrasonic 3d scanner that works in the air, using off-the-shelf components.
Ever since hearing about Rob Miles' Bitshift Variations in C Minor , a 4-voice polyphonic 16 minute piece of algorithmically generated music, I wanted to implement it in hardware. Getting it onto just any microcontroller seemed too easy , so I wanted it to run on the smallest µC I could find — the ATtiny4. A while…
I have just released a serial port based Amiga disk and file transfer tool, amigaXfer .
After beginning a compiler for the Apple M1 GPU , the next step is to develop a graphics driver exercising the compiler. Since the last post two weeks ago, I’ve begun a Gallium driver for the M1, implementing much of the OpenGL 2.1 and ES 2.0 specifications. With the compiler and driver together, we’re now able to run…
I made a custom guitar with hot-swappable pickups

For years, Wi-Fi packet capturing in the Mac has always worked reliably out of the box. Unfortunately, packet capturing is now broken in the new M1 Mac.
When we announced the PineTime in late 2019 we couldn’t have imagined how popular of a project it would end up becoming. From the very start, it was evident that this will be a project like no other in our lineup. Following 18 months of intense development, the InfiniTime has now reached a release version, and the…
