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
Resurrecting a dead interface
How accurate is Ikea's Vindriktning air quality sensor? This review covers PM2.5 behavior, limitations, and how it compares with better monitors.
ML, Biotech, Hardware, and Coordination Problems. Sometimes I write about hard problems and how to solve them.
Apple today announced iPhone 16e, a new addition to the iPhone 16 lineup that offers powerful capabilities at a more affordable price.

Source code and hardware schematics are available on Github: https://github.com/agranlund/wolf
Security reviews of modern Windows Active Domain infrastructures are – from our point of view – quite sobering. Therefore, we often look left and right, when, for example, examining the hardening of protection mechanisms of a workstation. Here, we often find all sorts of dangerous and ill-conceived stuff. We want to…
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.
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.
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…
NVIDIA’s latest AI servers can run on coolant warmer than a hot tub — and that counterintuitive choice is one of the biggest efficiency leaps in data center history.
BYD sold 4.6M vehicles in 2025, but Americans can't buy one. We CT scanned four components from its lineup to reveal what vertical integration looks like at the part level.
Introducing Robostral Navigate: 8B model achieving 76.6% on R2R-CE with just a single RGB camera. No depth sensors, LiDAR, or multiple cameras needed.
We have been very public about how reliable Samsung SSDs have been in the past, so we wanted to explain why we are now moving part of our line to Sabrent.
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...
