Last week my in-laws politely but firmly asked me to set up their new HP printer. I protested that I’m completely clueless about that sort of thing, despite my tax-return-job-title of “software engineer”. Still remonstrating, I was gently bundled into their study with an instruction pamphlet, a cup of tea, a promise…
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…
I’m using the iOS Bedtime feature for years now. With yesterday’s iOS 14 update the feature got moved from the Clock app to the Health app. Unfortunately the migration is done by disabling your existing alarm and showing a button to open the Health app to set it up again. I woke up late and well rested today.
August 6 is Andy Warhol's birthday, so let's look back at his pioneering digital art

ML, Biotech, Hardware, and Coordination Problems. Sometimes I write about hard problems and how to solve them.

The M1 is up *here*, running fast and cool, and all the competing chips from Intel, AMD, Qualcomm, Samsung, and whoever else are down *there*, running hot or running slow, looking around for their recently stolen pants.
The ESP 32 was the most fun side project for me in 2022. For those who don’t know: the ESP32 is a small, cheap and wifi-enabled microchip. Many smart devices that you buy on Amazon have an ESP32 inside. It’s really amazing what you can do with a board that costs less than a good sandwich.
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…
You can view a video related to this blog post here: Does UASP make the Raspberry Pi faster?. A couple weeks ago, I did some testing with my Raspberry Pi 4 and external USB SSD drives. I found a USB 3.0 SSD was ten times faster than the fastest microSD card I tested. In the comments on the video associated with that…
Last January the Dell XPS 13 developer edition (9370) made its debut. Today we’re excited to announce that one year later its successor, the XPS 13 developer edition (9380), is now available…
People still tell me that CPUs are boring. That nothing much happens anymore. Let us look at AMD Ryzen 7 processors from 2022 to 2024: the 5800X3D (Zen 3), the 7800X3D (Zen 4) and the 9800X3D (Zen 5). They are comparable 8-core chips with 3D V-Cache. I have written about them before, in How stagnant … Continue reading…
For the past half year or thereabouts I have been working on a little project of mine that I call 'NymphCast' [1]. The initial idea for it o...
A version of this article appeared in War on the Rocks. Controlling advanced chip manufacturing in the 21st century may well prove to be like controlling the oil supply in the 20th. The coun…

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?
Way back in late 2019 , I dissected a Reolink B800 IP camera to demonstrate the various parts of an embedded Linux system. It’s fairly nice hardware, actually—it has a 4K video sensor, a microphone, power over Ethernet, and is nominally waterproof. And yes, it runs Linux.
Update (May 15, 2019): This post was linked and its author quoted as a source in this Fast Company article on the same subject. Where's my webcam's off switch? Have you ever noticed that your webcam doesn't have an "off" switch? I looked on Amazon, and I couldn't find any webcams for sale that

This article is the second entry in a series about the "3D cards of the late 90s running Quake". The first entry [1] took a look at the end of 1996 with the Rendition Vérité 1000 and its dedicated port called vQuake. Rendition had managed to beat everybody to Quake-market. For a brief period of time they had the one…
