If there is a "spirit" to open source, it's a lot closer to "I can take software that you released and use it however I please, while also possibly releasing my changes so that you can do the same" than "Beca

A PSA test is easy and non-invasive and I personally wouldn't skip it. But keep in mind that it doesn't have a lot of diagnostic accuracy by itself, and the false positive rate can lead you to do things that are more invasive than

A few more interesting observations: It doesn't seem to have any on-chip flash. While this is a common scenario on application processors and FPGAs, this is unusual on a modern microcontroller. It's not really a problem... XIP fla

The ESP chips draw obscene amounts of power, this one probably won't even get warm.

The Cortex-M0 instruction set has some rather unfortunate limitations [1] that can make it difficult for compilers to generate good code for shared/concurrent data structures. I can understand why they took this route on a first silico

I own a pile of antennas for ham radio, I own a bunch of TV tuners, because they're usable as software controlled ham radio receivers, I own a television, and I own a laptop that sometimes gets plugged into that television. That might

I agree with the rationale that software should be kept up to date. However, if this was their only concern, they would make it easy for updates to be applied automatically, and then would make this the default. But the rationale for compl

Snaps require you to allow each publisher to automatically push arbitrary software updates to your machine, and snap deliberately does not allow you to disable this misfeature. It's not a bug or an oversight -- it's part of th

What the hell, here are a bunch of half-baked ideas that I haven't made time for because I'm lazy and stressed out and exhausted. Would love to hear if any of these sound interesting. 1. Designing a protocol for an amateur radio c

Yes, using patents. They got lucky and a handful of their early patents became required parts of early cellular standards. Since then they've lobbied the standards bodies to include features that require their newest patents. When that

Even as an engineer, I usually draw a line between "stuff I like to hack on" and "core system components that I'd rather not touch." I'm fine pulling a dependency from nightly for a project I'm working on,

Now that storage is infinite and cheap, it's become trendy for engineers to never actually remove anything, but to just set a "deleted" flag in a database somewhere. This makes a lot of tricky things easier, but there are pit

There aren't a lot of advantages to VHF/UHF over the direct microwave links that they're already using (and a handful of disadvantages), so it's probably not likely. The big perceived advantage to HF is eliminating all o

"Linux on LiteX-Vexriscv" [1] is a fun way to get started. The readme includes a table of supported boards, as well as the amount of memory and maximum tested clock frequency. I played with it on an OrangeCrab [2], and was shocked

Most of the robotics expertise that you're attributing to NASA is actually JPL. JPL may technically be a NASA lab, but it has been managed by Caltech since 1958, unlike every other NASA center. JPL employees work for Caltech, not NASA.

The PC was still in its exponential growth phase during each of these transitions. So the total number of computers built with 5.25" vs. 3.5" drives likely differed by at least a few orders of magnitude. Today's USB/SD-o

I think it's more inertia than any of these things. The entire point of this thread is that (a) is false -- see grandparent and the xkcd joke. It's not easy. It pretends to be easy, but is usually broken in some crazy way instead.
