I built my last hackintosh in 2014 and it was overdue for an update. Since Apple recently updated their iMac with Core i9s and skipped the T2, this is probably the last time I'm building this sort of computer, before MacOS is locked down forever. Unfortunately, nothing in their lineup fits my needs, hence I chose to
Learn the microarchitecture-level details of the processor that enable to execute two threads at the same time on a CPU core
I bought a datacenter GPU that doesn't fit in a normal motherboard, macgyvered the fan with jumper wires, and now I'm running a model that ties with Claude Sonnet 4.6 on benchmarks, all for £200.
Maybe a poem will help remember complicated power-saving settings for SSDs. Here goes. "ALPM for SATA, not N-V-M-e. The latter needs ASPM, and A-P-S-T"....
For the past two weeks or so, I've been working on constructing the Taylorator. The Taylorator is a piece of software which allows me to flood the FM broadcast band with Taylor Swift's music. No matter where you tune your radio, you will only be able to listen to her!
Here's another iteration on the Zero Terminal projects I've been working on for a few years. For those of you who haven't seen them, I've been trying to design the most usable all in one Pi Zero computer out there.
BusKill is a Kill Cord for your laptop implementing a Dead Man Switch using $20 in USB hardware + udev rule to trigger your laptop self-destruct if stolen.
Better 32-bit performance was worth trading some 64-bit performance to get
(Hat tip to the late Bill Strauss and The Capitol Steps' Lirty Dies.) A few moons ago I was thinking of ways to take my Palm OS Fossil Wr...
I bought a Rodecaster Duo to solve some audio woes, and found that it has ssh enabled by default. I captured the firmware update process and created custom firmware to enable password authentication for ssh.
In June of 2010 I moved to a place in Montana with only electric heat. By myself. In the past few winters I had conducted experiments in cutting the amount of energy I needed to stay warm, with a focus on heating myself instead of heating the whole house.
49 graphics cards. 30 years. From Quake to Cyberpunk.
I'm increasingly of the view that both my time and my sanity are worth more and more as the years progress. Particularly in my independent life, it really can be that black and white - if I can't work, it costs me money. Plus, I want to be happy
This is the encyclopedic blog post I wish I could have read when I started designing my CNC router.
In the spirit of my thermostat and dishwasher controller , I managed to cobble together a decent blinds opener in a short weekend almost entirely from spare parts on hand. This design is very much what I could do quickly with what I had, so probably not worth copying, but perhaps it can be an inspiration.
Yesterday I had the idea that it would be cool if I turned a Nintendo Switch (will be referred to as NX to avoid confusion as NX is the code name for the Nintendo Switch ) console into an actual network switch. I thought about it a bit and realized that it would be doable in hardware at least, since the NX docking…
“Oh, that’s a nice button. It has a good click.” “Is it a $550 click?” I asked. He clicked it a few more times. “It’s not *not* a $550 click.”
A quick cli script to tell you if your usb-c cable is bad
Q1. Did you see Microsoft’s announcement?A. Yes, thanks, you can stop emailing to ask! Microsoft’s Chetan Nayak was even kind enough to give me a personal briefing a few weeks ago. Yest…
Earlier this year I designed a very basic box/organizer for AA and AAA batteries in Autodesk Fusion, making it parameterized so that by changing a few…
Some pics, endorsements, and the reason the book exists in the first place.
TLDR: My Macbook Pro 16" is hot and noisy when connected to a 2560x1440p60 monitor, even when idle and the lid is closed. This article…
This is the Compute Blade, and I'm test driving it in a four-node cluster: I'm testing the Dev version, and @Merocle from Uptime Lab sent four Blades, a 3D-printed 4-bay case (a metal 1U rackmount enclosure is in the works), and two fan modules. He's been testing 40 of these in a rack at Jetbrains for months, and…
The new $30 AirTag tracking device from Apple has a feature that allows anyone who finds one of these tiny location beacons to scan it with a mobile phone and discover its owner’s phone number if the AirTag has been set to lost mode. But according to new research, this same feature can be abused to redirect the Good…

Dmitry.GR: How to reverse engineer a completely undocumented microcontroller. From nothing to a full SDK in one week flat!
I've been following WisdPi's development of various 5 Gbps and 10 Gbps Ethernet adapters for the past couple years. They use newer Realtek Ethernet chips, which sometimes have performance quirks—most frequently encountered under Linux. In today's video, I tested the new WisdPi 10G Ethernet Expansion Card for Framework…
