Today, on the 59th anniversary of the launch of the Sputnik satellite, the 6th generation XPS 13 developer edition makes its debut in both the US, Canada and Europe. This Kaby Lake-based system co…
2024 Nano Texture Macbook Pro on the left; 2021 Glossy Macbook Pro on the right TLDR: the Nano Texture performs wonderfully anywhere where light used to be a factor and used to force me to shade my screen or avoid the place entirely. I’m less concerned with where I sit indoors. Coffee shops / offices with skylights or…

In my previous blog post, I compared the performance of my new ARM-based MacBook Pro with my 2017 Intel-based MacBook Pro. I used a number parsing benchmark. In some cases, the ARM-based MacBook Pro was nearly twice as fast as the older Intel-based MacBook Pro. I think that the Apple M1 processor is a breakthrough ……
Today Raspberry Pi launched their new $130 AI HAT+ 2 which includes a Hailo 10H and 8 GB of LPDDR4X RAM. With that, the Hailo 10H is capable of running LLMs entirely standalone, freeing the Pi's CPU and system RAM for other tasks. The chip runs at a maximum of 3W, with 40 TOPS of INT8 NPU inference performance in…
Next time you look at a transmission line, I hope you'll focus on the big four properties: characteristic impedance, high-frequency loss, delay, and cros...
Intel's groundbreaking 8008 microprocessor was first produced 45 years ago. 1 This chip, Intel's first 8-bit microprocessor, is the ancesto...
A laundry list of speed limits that your code can’t exceed.
100x More Efficient than Arm?
In the past months, Tesla has been offering a free, one-month trial of their full self-driving (FSD) system to all current owners. It looks like they are rolling this out in stages, because I only got mine only a few days ago.
The instructions below set up Time Machine using the Apple File Protocol (AFP). After publishing this blog post, I’ve been told that this is now deprecated and that Samba should be used instead. I’ll update this blog post in the near future.
A guide to the operating principles, techniques and technology in lidar systems for self driving cars.
Symbolic of the transfer of power from IBM to Microsoft?
What does it take to build a little 68000-based protoboard computer, and get it running Linux? In my case, about three weeks of spare time, plenty of coffee, and a strong dose of stubborness. After banging my head against the wall with problems ranging from the inductance of pushbutton switches to memory leaks in the…
When you buy a USB charger, how do you know if you're getting a safe, high-quality charger for your money? You can't tell from the outside...
I wasn't entirely satisfied with the aluminum cube , so after thinking about the design for a while, I decided to make another one out of stainless steel. Just for fun, I thought I would make all the pieces using only manual machines. How hard could it be?
Christmas is coming again, and generally that means christmas trees and everything in it: lights, streamers, and ofcourse baubles. The holiday is all very jolly and everything, so I decided it was lacking some doom... errm, I mean Doom. So I 3d-printed a small Christmas bauble modeled on an IBM PC, stuffed it with the…
USB-C offers exciting new capabilities, including external monitors connected through the USB port. USB-C converters to DisplayPort or HDMI are common and inexpensive. USB-C hubs with external monitor support are also common, but understanding their capabilities and limitations can be extremely confusing. Some are…
The new MacBook Pro shows that Apple is finally becoming serious about developers.
For decades, my perception of USB was that of a technology both simple and reliable. You plug it and it works. The two first iterations [1] [2] freed PCs from a badly fragmented connector world made of RJ-45 (Ethernet), DA-15 (Joystick), DE-9 (Serial), DIN (PS/2), SCSI, and DB-25 (Parallel). When USB-3.0 came out…
I loved my Nokia 5110 and I wonder if it was possible to breathe new life into this long-shelved and still-memed mobile phone. As it turns out, not only is it possible, but it's going to be a lot easier than I anticipated.
Verilog is the de facto abstraction for programming today’s FPGAs. RTL programming is fine if you want to use FPGAs for their traditional purpose as circuit emulators, but it’s not the right thing for the new view of FPGAs as general-purpose computational accelerators.
