Nice build! I work on...similar actuators and, well, it's a lot easier to just drive the steering column. :)

No. Mach's airspeed, FlightAware is showing ground speed. Someone's got a great tailwind.

Ok, I'm on a project that just picked N54 processors for a set of new designs. W/O arm cores it wouldn't even be considered. The RISC-V cores are useful and will be put to work, but they aren't exactly a selling point. W

Well...back when I was working in Boston-based companies, I spent many a day at Northeastern interviewing intern candidates there. I didn't have too much trouble finding promising programmers there. So, yeah, I guess it works.

This. And even knowing the long-term trend isn't a guarantee that you'll make money. Look at the late 90s: knowing the internet was going to be a huge thing was obvious, but it didn't necessarily translate to knowing who the

A couple of things stand right out here: a) There's almost no time horizon here, so it's basically day trading. It's not enough to know what happens, everyone else needs to "do the right thing" in a short time horiz

"once we have a large enough customer base, we're going to jack our fees and our early adopters will need to find a new payment processor." Seriously, customers are on to this and don't need the hassle. If you can't

Great build! And I've been looking for something like the Ploopy trackball for -ages_. :)

Those sorts of systems run in realtime. They neither know (or care) who you are. They work by identifying people and pulling out appearance characteristics (like blue coat/red hair/beard/etc) and hashing them in a database. A

Sometimes shell is the only thing you can guarantee is available and life is such you have to have portability, but in general, if you've got an enormous shell app, you might want to rethink your life choices. :/

Do a search for 'UnitedHealth uses faulty AI to deny elderly patients' and see what comes up. I'm not saying this is deserved, more that I'm surprised it's taken this long for someone to just up and execute an insur

Not really. Different cameras, both old and new, draw differently. It's not a question of "good" or "bad". Sometimes I want a nice, sharp image, sometimes I want the scratchy, somewhat random image I get from a Holg

Umm...I've got an old HP 1.3? MPix digital camera that I hang on to because, yeah, I like how it paints. The sensor acts as if it has a slow focal plane shutter and that combines really nicely with some specifics of how I take pictures

Low price normally requires lower margins, so for the same risk, you're making less money than with a higher end model. Make it up in volume, you say? Well, that increases the risk that you don't sell enough and end up with a loss

It's not even a question of 'good' so much as 'the same as everyone else'. CAD drawing pass through a huge number of hands/companies in the process of getting physical goods made, and any slight compatibility p

Lots of manufacturers are going to encrypted CAN to prevent these sorts of injection attacks. Of course it also makes life far more difficult for third party part suppliers. :/

This is really interesting. As someone who's been gradually losing his vision, I've noticed some of this stuff on my own, but it's nice to see a good writeup so one doesn't have to figure out everything from first princi

At least with the missile case, someone _did the analysis and knows exactly what's wrong_ before deciding the "solution" was letting the resources leak. That's fine. What always bothers me, is when (note, I'm not sa

FPGA is clearly more _practical_ if you're trying to bang out some commercial functionality. Still, making your own chip fab is cool to do in it's own right. :)

It's unlikely that the multiple CAN buses are being used to increase speed by, say multiplexing them. In general, vehicles use multiple CAN buses for enhanced security. For example: things like diagnostic ports are often on their own C

Have you dealt with publishers? If a work is out of print for a few years, much better to have rights revert to the creator.
