Yep. Another thing to watch out for is using bitfields to access device registers. One time, I was working with an older embedded PPC architecture on a driver to talk to an FPGA that was attached to a 32 bit local bus. The problem is that i

I had a dentist appointment before COVID. They found a cavity and scheduled me to have a filling. Then, COVID hit and I cancelled the appointment. I went back two years later for another checkup/cleaning. They didn't find any cavi

Curtiss-Wright isn't just some random nobody in the industry. They literally make black boxes (crash recorders) for planes, for example.

Does the same go for Peltier plates and thermocouples?

For what it’s worth, we normally aim for < 50 nanoseconds RMS on our systems with PTP. You can get even better if you combine it with synchronous Ethernet.

The term in the community is “burble tune” and, yes, it’s extremely annoying and lame.

Well now I feel like an idiot for signing up. Is there any way to have ID.me delete all of my records? Or is that a lost cause?

Dr. Friedman and team at UPenn are working on exactly this. An mRNA based prophylactic (and also potentially therapeutic) vaccine for HSV. I think they were originally using some other form of vaccine (a protein vaccine?), but then realized

Every time I hear "lead poisoning" mentioned, I have flashbacks to myself as a child playing with my Dad's lead fishing weights like an idiot.

Because that's a lot more obscure. A better example might be asking something like "what's the difference between cache and RAM" or "what is a CPU register", which I'm starting to think will still catch ob

I hear ya. I would definitely not disqualify someone for not knowing the answer. In fact, someone who is able to sort of work through the problem on the spot may even be preferable to someone who just knows the answer because they happened

I think it depends on the job. If this was for an embedded/firmware engineering position, I'd expect a level of EE knowledge that would at least make the concept of everyone's phone sending data to a satellite be a non-starte

Same. I was having PVCs, which felt like skipped beats, but it's actually a premature contraction (that you sometimes can't feel) that occurs between beats, so there's a compensatory pause, so it feels like there was a skippe

This happens on my BMW too (2011 3 series). I’ve also had traction/stability control activate when hitting a large bump due to the slight change in wheel speed as each wheel goes over it.

> To fix this you need a persistent low water mark on the time Yep, this is what many GPS receivers do to deal with the 20 year issue. They burn their manufacturing date, so they know which "cycle" they're in.

I've implemented the 1588 protocol a couple of times, and I have less optimism. This "era" thing seems like the exact type of thing that someone would ignore when implementing the protocol, or if it is supported, probably doe

I do embedded development and I use Glibc on all of our products. It's as simple as checking the box in Buildroot, so why not? The version of Glibc I am using has special accelerated memcpy and string functions for my CPU (e6500 PPC, A

Yep, I'm positive that it's HDCP 2.2, but I don't think I should post a link here for obvious reasons. I also don't remember which one it was, but it was a switch capable of 4k60 (HDMI 2.0). There was a forum where a guy

For a while, there were HDMI splitters for sale on Amazon that would effectively strip out HDCP 2.2. I haven't checked in a while, but I bet that's still the case. It seems like these DRM efforts are futile, but then I remember th
