Of course, when you get to buildings that are old enough, you have several layers of solid material (brick/stone) on the exterior, as well as things like double-thickness brick interior walls as well. This doesn't do RF propagatio

Do people really stare at the license plate in front of them anyways, though? It was made quite clear during driver training courses many years ago not to do this and that your glance pattern should always start and return to near the horiz

It's not at all a bizarre argument in a labor shortage. Exactly what you should expect to happen is that low-value economic activity gets replaced by higher-value economic activity!

Components for producing SDRs are impacted by the overall semiconductor shortage very significantly, too: keeping stock of what are fairly niche products is difficult when times are good, but with component lead times in the 52-80week range

There's also a not insignificant number of employers that use their status as one of a very few employers in town to abuse employees, either in salary or otherwise, because the barrier to quitting is "do I want to uproot my entire

And yet, people keep coming to San Francisco, LA, and other cities because there is work there. You can't look at housing costs divorced from other costs of living, either: for example, moving to places that are "dirt cheap"

The dirty secret is that shipping is a rarely profitable industry, so the "owners are too cheap" aspect is really the owners trying to go out of business as slowly as possible, hoping that times will improve in the future: if the

2754 tonnes is not really considered a large amount of material on the scale of global logistics. That's even closer to "regular weekly/monthly delivery" numbers than a large or special shipment.

Don't forget that if any company were to do litigation completely in-house, the second they were involved in one major litigation would be the perfect time for anyone else to take the company to court -- their lawyers are already all b

Yeah, but if you're not already in the job, the distribution of "teams that are currently hiring external candidates" can be quite skewed towards the worse side of things, and if you don't know this going in, you'll

What's also interesting is that transportation & communication are very much easier than they were for past generations. This is also combined with shorter times that a worker stays at a single job before moving on for another oppo

One of the issues is that the contracts are overly specific, can be extraordinarily difficult to change, and are not written by experts in the job to be done. There's always tension between "you need to be absolutely specific in o

Yep, we're hearing 52week lead times on pretty much all microcontrollers at the moment, with more esoteric parts being... somewhat more than that. A year ago you could buy 10k+ units of most common parts -- in stock -- from each of the

The Artix-7 is an excellent series of devices for learning how to work with PCIe. You're limited to Gen2 speeds, but that's not an issue for developing most applications. One thing to keep in mind is that "Artix 7" is an

It is absolutely standard practice for this to happen. At contract completion, the contractor must destroy or return all classified materials: these sorts of designs would certainly be included. It's pretty interesting, but a lot of th

You absolutely do assume that that network is hostile/compromised. There are a number of other networks in other places where more important communications are done. It's a giant PITA, and a lot of stuff leaks from Congress becaus

Their geocoding seems to work decently enough for street addresses from what I've seen, which is what it's technically advertised to do. It doesn't have a Google-sized database of business entities, so I'm not surprised

It's somewhat economics of scale, but also that small/cheap FPGAs are sized rather closer to what you'd expect in a microcontroller (and that is quite sufficient for many designs). Supporting PCIe and other high-speed interfa

Read the BSD license. There's nothing preventing the code being redistributed in another product (in this case, Mapbox JS v2) under any license terms whatsoever, as long as the copyright holders are appropriately credited.

I can't disagree more strongly about this. Many, many times I'm trying to understand a codebase, and what I have is that codebase, not the dozens of dependencies involved, and not a full development/build environment. I may n

Tegra started out as their mobile chip, but has evolved into their robotics/automotive/industrial-SoC platform through the Jetson series of modules which are alive and well. [Sidenote: this has resulted in the hilariousness of tak

I think the difference is that you're using the language as a prototyping/design language: there, shortening the feedback loop is absolutely critical. There are lots of things that are not prototyping though - when I touch a graph

You also get the benefit of hiring several devs that already trust one another and have experience working together without stepping on each other's toes. That's where you can look at the product they have already developed and fo

You don't even need to do this: qemu support for executing arm64 binaries is fairly good, so you can just run the builds on your beefy x86 server anyways.

I think most of your issues are equating "QEMU == vmware player" or something like this. It's really not: as a matter of fact, QEMU is just a processor emulator, in software. It's not a full-operating-system VM environme

Quaternions are also quite a bit more efficient (both in flops especially when composing rotations frequently) as well as storage space (4 values in a quaternion vs. 9 in a 3D rotation matrix). It's interesting to compare disciplines,

Not everyone's development environment is connected to the Internet. Additionally, trying to compile the project from source is extremely painful compared to most projects: it's not really possible in any obvious way to duplicate
