The problem was that they had so little room for error. But I guess landing a rocket vertically on a heaving ship is also tricky, so maybe the problem is surmountable.

Do you happen to remember any specific textbook? I'd be interested to see an example, assuming that they're still available in some format.

It's a general rule of thumb, so it wouldn't apply to proper nouns, but I did edit to specify verbs rather than all words in general. I do appreciate the irony that the example I chose breaks that guideline.

Unless it's a verb that ends with -ano. In that case, stress the preceding consonant. It's kind of like the difference between urAnus and Uranus. There are other exceptions, but that's the most common and important one.

There's also a floating point expression generator that tries to make your calculations more accurate, but it doesn't seem to give an analysis like this. These two tools would seem to go well together.

Tilting your head to look at opposite edges of the screen can irritate the neck.

It's a simple and general method that works in many domains, which is an usual combination.

The other ways of solving the example of arbitrary heat sources and sinks on a plate range from hacky combinations of simpler methods, to tedious math, to complicated general methods. If you switch from heat to pressure distribution, you'd have the same types of options, but the specific methods would be different.

I've read the USB PD spec. What's wrong with it? It seems ok to me compared to other specs. And yeah it's long, but different sections are for different people with different roles.

In my anecdotal experience, the problem is that many programmers just don't like working to a spec.

True. I take back what I wrote for being too reductive. Well said.

That's not at all what I'm saying. Aside from web development, most professional tools are only used by professionals because they cost money. It wouldn't make sense to judge something by the free toy versions that happen to exist.

I think they're saying that the switch was justified because the workforce is no longer familiar with Ada.

Ada is mostly used by professionals, not enthusiasts. It has a captive audience of governments and companies working on safety-critical systems where they have strict toolchain requirements or legacy systems. Pretty much the only thing that can move those users off Ada is to retire older systems, and rebuild their processes for C++. That's tough to justify when the language and ecosystem are still actively developed (paid, not free tools). Things like a language server are unimportant when your IDE must be qualified, and you're not allowed to install or use any software of your choosing. You will never see most of what goes on with Ada outside of a work environment. Its continued use is largely unaffected by anything you'd see in the open source community.

I binge-read the RAQs a few months ago. So much great information. Thank you!

I also appreciated the consistent URL scheme because it let me easily scrape all the PDFs to read them offline. The one bummer is that the links at the end of the PDF versions seem to be broken now.

They have a cool PDF cheat-sheet related to this which doesn't seem to be linked from the page.

Assuming that the backyard is for playing and the front is ornamental, you can keep the backyard as grass and transition the front to plants.

OnlyOneCannolo — Fri, 04 Jun 2021 15:46:48 +0000

Because it's still a town? It just happens to also have a college in it. The transient population results in more stuff (industry, services, transportation, ...) than you'd get otherwise, minus the traffic and real estate prices. There are still people of all ages just like any town. You have to go out of your way to meet students, so just don't do that.

It depends on whether you're talking about electron flow or conventional current, because they're opposite each other. The original mnemonic is incomplete because it doesn't specify to which it refers.

It could be probing the response to a drone intrusion for the purpose of using drones as weapons in the future.
