In 2018 I made the first lithographically fabricated integrated circuits in my garage fab. I was a senior in high school when I made the Z1 amplifier, and now I’m a senior in college so there are some long overdue improvements to the amateur silicon process. The Z1 had 6 transistors and was a great test chip to…
In March, I got an email from SpaceX saying Starlink was available at my address, and I could pre-order. I paid $500 for the equipment, plus $25 for a Volcano Roof Mount, and $99 for the first month of service, and a few weeks later, I got the kit you see in the image above. I was a little too excited about getting…

The monitor story for Apple computers in [nearly] 2022 is basically would you like garbage, or would you like to take out a home equity loan?
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…
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.
I fancied getting an eink screen to use for future projects. I bought a wee one with a raspberry pi "hat" attached. However, I realised later that I could maybe just re-purpose an old Amazon Kindle eb…
When a program is mostly just accessing memory randomly, a standard cost model is to count the number of distinct random accesses. The general idea is that memory access is much slower than most other computational tasks. Furthermore, the cost model can be extended to count "nearby" memory accesses as free. That is…
Introduction Last week, we talked about using a new Apple M1 based Macintosh as a development workstation and how installing Apple’s development system XCode also installed a large number of open s…
Complex software is, to put it mildly, hard to get right (for details, see almost any other posting on this or any other security blog). Especially for gadgets that are rich with microphones, cameras, location and environmental sensors, and communication links (such as, you know, smartphones), errors and security…

When M1 Macs were launched, a new GPU with iOS-like architecture started driving the external monitors. This meant that the old method for controlling monitors using DDC wouldn't work anymore. Apps like Lunar and MonitorControl had to find other ways to change the brightness of the monitors.
In the mid-to-late 2000s, you either knew, or were, that kid in grade school. You know. The one who could put games on your graphing calculator. You may be surprised to learn that some of these people didn’t exist totally in a vaccuum. There was in fact a thriving scene of hackers who had bent these calculators to…

Microsoft’s hardware legacy stretches back more than four decades to the early days of personal computing. As Windows built and inspired new computing experiences, new Microsoft hardware accessories helped people interact with them. At this interse
The most powerful and advanced iPad Pro ever pushes the limits of what’s possible on iPad with the addition of the Apple-designed M1 chip.
I have been long wanting a PDA of sorts with an E-Ink screen that allows me to read stuff on the Internet without eye strains. But the Kindle really sucks as a newsreader device because the experimental browser never works correctly.
Apple has revealed the hidden Fallback Recovery OS mode available on M1 Macs. How to enter and use it, and why it’s another big plus.
A series where I’m documenting my process of designing and building an e-ink laptop.
When the Compute Module 4 was released (see my CM4 review here), I asked the Pi Foundation engineers when we might be able to boot off NVMe storage, since it was trivially easy to use with the exposed PCIe x1 lane on the CM4 IO Board. The initial response in October 2020 was "we'll see". Luckily, after more people…
14 November 2022: This blog has been updated to remove the link to the preview form. Last year at AWS re:Invent, Jeff Barr wrote about the exciting availability of Amazon Elastic Compute Cloud (Amazon EC2) Mac instances. Today, we’re announcing the preview of a new EC2 M1 Mac instance. The introduction of EC2 Mac…
Let me start by saying that the reMarkable 2 is a great device. I’ve wanted something like this for a long time: a relatively open device that runs Linux with an eInk screen and the ability to write on that screen with a pen. The reMarkable 2 delivers: I can ssh into it, and there’s a whole bunch of people writing…
