No product gets built without at least one good supply chain war story – especially true in these strange times. Before we get into the details of the story, I feel it’s worth understanding a bit more about the part that caused me so much trouble: what it does, and why it’s so special.
Ethernet rules everything around us, a large proportion of our systems communicate to each other with ethernet somewhere in the line. And the fast pace race to the bottom for embedded systems means that almost all network equipment is smart to some degree these days.
If I multiply two 64-bit integers (having values in [0, 264)), the product requires 128 bits. Intel and AMD processors (x64) can compute the full (128-bit) product of two 64-bit integers using a single instruction (mul). ARM processors, such as those found in your mobile phone, require two instructions to achieve the…
I started a new job recently so I had the opportunity to get one of the new M1 MacBooks, I decided to go with the Air. The reviews have been very positive and I’m here to tell you: it is indeed an amazing device. The performance feels a lot better than my MacBook Pro 16”, which is only a year old and about 3x the…

For a little over a decade, they enjoyed strong popularity among mountain bikers, but then the feelings got cold.
Due to COVID, I haven’t been getting my usual amount of exercise this year. To help with that, I decided to take a chance and order an under-desk exercise bike to get some extra cardio. The bike I bought is decent: it has good tension, stays in place, operates quietly, and offers Bluetooth connectivity for tracking…

By training Atlas to maneuver its way through complex parkour courses, our engineers push the humanoid robot to its limits.
There’s a great joke in Futurama, the cartoon comedy show, about a horror movie for robots. In the movie, a planet of robots is terrorized by a giant “non-metallic being” (a mons…
It’s bad out there for customers of electronic parts and components. The semiconductor shortage is so severe it’s being covered by mainstream media; meanwhile, various politicians have tasked their aides with looking at the global supply chain. Indeed, in the short term, the dearth of chips is already leading to…
In this post I discuss how you can upgrade a NAS Server by adding Thunderbolt 3 for lightning fast connectivity at 20 or 40Gbps. This particular implementation is specific to an Apple Mac Mini M1 and
The P cores in the M1 Pro/Max CPU are managed in two groups of four, sparing load on the second group, and distributing it unevenly within each group. Its two E cores outperform the four in the M1 …
