"This Is Not A Film" by Iranian director Jafar Panahi, who is under house arrest in his country for alleged “propaganda against the regime,” will be screened under the Free Jafar Panahi Program of the 13th Cinemanila. The film was smuggled from Iran in a Flash-Drive hidden inside a cake to Cannes for screening a few…
Today we're comparing one of each generation of Pi from the Pi 1 to the Pi 5 to see how their performance and specifications have improved.

M&M sorting machine using electro magnets to send the M&Ms down the correct chutes. Uses an Arduino with a Bluetooth module to control the magnets.
How I built a Sega Mega Drive dev kit from scratch: reverse engineering the cartridge slot, a homemade logic analyzer, a RAM cartridge and boot firmware.
This week I finally moved my gaming/Linux PC into my little office rack—it's that 2U box above the UPS at the bottom: I remembered seeing Linus Tech Tips' 4U build in a video a couple years ago—but he has a full 42U rack in his basement. I don't have that much space—just 2U (technically 3U if I wanted) in my little…
It has been 0 days since the last change to my home server.
In 1993, Jurassic Park came out and revolutionized the use of CGI in films [1] . To the public the experience was magic. But for some of the people in the movie industry, it was a rude awakening.

Instructions to build your own 3D printed bluetooth headphones from readily available parts. All you need is a 3D printer and basic tools.
While there are downsides, using a read-only root filesystem will dramatically increase your Pi SD card's lifetime.
When you read up on the DisplayPort connector in the VESA specification, it will show that both the source and the sink are supposed to provide power at 3.3V+-10% and 500mA on the DP_PWR pin, pin 20, of the connector.
So I've been curious about what kinds of displays you can connect to the Pi-series single board computers for a while. I happened to accidentally order a few. Among others an eInk display. I ordered the PaPiRus ePaper. It ended up being dead on arrival and then out of stock so I received an Inky to replace it. Fair…
When I start studying a vintage system, the first thing I like to do is understand how its components work together at the hardware level [1] .
An RTL performance erratum in the Apple M3 Neural Engine throttles DRAM weight streaming throughput down to 17–19 GB/s from the nominal 45–60 GB/s, whenever the total weight size is an integer multiple of 1 MiB, which currently affects 7 of ANEMLL ’s 15 models. Avoiding the problematic path in the kernel DMA engine's…
Having a home server and a few smart plugs leads to interesting data points like this one. Well, interesting to me, at least.
It turns out that a _very_ long HDMI cable, a Steam Controller 2 and Bazzite on a second drive was all I needed to get a comfortable couch gaming experience.
The Intel 8086 microprocessor was introduced 42 years ago this month, 1 so I made some high-res die photos of the chip to celebrate. The ...
We've been restoring an Apollo Guidance Computer 1 . Now that we have the world's only working AGC, I decided to write some code for it. Try...
Smartphones have a thumb problem. The touchscreen is a magical invention, but it definitely has its shortcomings.
I’m going to get straight to the point and say that it’s time for Robertson screws to be retired and supplanted by Torx. This posting is to explain why and is partly motivated by lots o…
I’ve got this rock64, which is an aarch64 board comparable to a Raspberry Pi 3 B+ with 4 gigs of ram. For years I’ve wanted to put a distribution on here that doesn’t have a premade image available, mainly because out of all the options on that page I don’t actually like any of them. Well, except NetBSD, but NetBSD…
A few days ago I had to replace the old IP camera I use to watch over my dogs and cats, and found out that IP cam technology changed a lot since I bought that old camera. IP cameras are now low-price and ubiquitous. I bought one of those generic models and installed it at my home, expecting to use the same software…
Anybody who has ever taken an advanced computer architecture class has heard of the CDC6600, which was the world’s fastest computer from 1964 to 1969. It was the machine that put Seymour Cray…
I used Ghidra twice, so that means I'm officially an expert in reverse engineering
The Open 7400 Logic Competition is a crowd-sourced contest with a simple but broad criteria for entry: build something interesting out of discrete logic chips. It's now in its second year, and this time around I was inspired to enter it.
Photo by Kevin Steinhardt When Azeem asked me to give a talk at CogX, he asked me to focus on just a single point that I wanted the audience to take away. A few years ago my priority would have bee…
Dmitry.GR: The first complete documentation of Sony Memory Stick from HW to DATA
I’m beginning to think that the Windows PC that I built in 2015 is ready for retirement (though if Joe Biden can be president at 78, maybe this […]
