Don't be quite so complacent in what you think students CAN'T do, especially saying "far beyond what students can do". When I was 16 I was writing assembly language competently, if I were 16 now, I would be (successfully) finding ways to tunnel stuff through normal HTTP traffic via a machine outside the network (it's not hard, certainly easier than learning asm). In a school of any appreciable size you'll have at least one student with the capability to do this.
Do other people genuinely hear ringing (like the repeated sound of a bell?) or is it just a figure of speech?
Mine doesn't sound like a ring, it's a continuous tone at what seems about the frequency of a CRT TV flyback (about 15kHz or so. I went to the effort of putting my signal generator through headphones and turning the knob until it matched the constant tone I always hear). It never goes away. I can ignore it though, but it never goes away regardless of whether I'm in silence or a lot of noise.
If he does it commercially, yes.
It's an FAA matter because the FAA regulates the National Airspace System in which this RC aircraft was flying. No one else regulates airspace in the United States, not cities, not states, airspace is a federal matter and many cases have settled this (for example when cities try to enact their own overflight rules, the FAA slaps them down, and has been doing for a long time). It doesn't matter what you're flying, you are still subject to 14CFR if you fly something. It doesn't matter how small or light it is.
The FAA doesn't regulate cars, RC or otherwise so the RC car example is not relevant.
Change is only constant if the degree of the leading term is 1
Anyone have any examples of the "rarefied vocabulary" used by the SAT?
On a point of pedantry, there was powered heavier than air flight over 100 years ago (the Wrights flew 110 years ago).
There are a lot of "coulds" in this article.
Saying it would be a match for the Spitfire is probably wishful thinking - just because it can go fast in a race doesn't mean you can mount weapons on it and still have it go as fast. It also may have handling issues that requires very high pilot skill to land and take off - and you have to remember that in WWII pilots were let loose on Spitfires and the like with relatively low hours. There may also be other problems that would surface (which is possibly why they don't want to go over 200 mph with the replica) such as it may suffer from flutter at high speeds; flutter will destroy an airframe in seconds.
I switched from iPhone to Android after using iMessage extensively and did not have this problem. So clearly it depends on some particular status/configuration of all the involved parties.
Does this depend on:
1) Moving the SIM from your old phone to your new phone
2) Leaving your old phone on and connected to WiFi so that iMessages still sees you as being on network
Or something like that?
I know that when I switched, it was a really quick thing—new Android phone arrived via USPS, pulled my old SIM, put it into new phone, turned off old phone, and away we went. I was in mid conversation with several people and never experienced a hiccup over the course of the day. Even talked about it over SMS—complained about the default keyboard on the new phone and all kinds of stuff.
Wasn't aware of this issue and didn't experience it. What gives?
My personal experience with IBM says no, they don't abuse L1. I used to work for IBM and went to the US for a while on an L1 visa. I was *more* expensive to IBM than a local worker because they paid a pretty sweet per-diem rate to me for the full duration I was there (in IBM, an international assignment works like this - you still work and are paid by your home country, and it is treated like a very long business trip effectively - so you get an International Service Allowance).
To give you an idea of how much I cost IBM, my international service allowance was good enough that I didn't spend my salary - I lived entirely off the ISA. That included learning to fly then running a private aeroplane (albeit a modest one). The salary I banked means when I got back I could buy quite a nice house with a very small mortgage. By the way, I live in a part of western Europe where property prices are stupidly high (similar to prices in the SF bay) not some 3rd world country where the money goes a long way.
They were constantly trying to replace me with a local person because I was too expensive, but I had specialist knowledge (the reason I was on assignment) which kept me out there.
The chip is open source because you can study the source code (actually it's more akin to Free because you not only can study the source code, but you can redistribute it, modify it etc.)
Open source has nothing to do with the amount of money you need to spend to build a functional machine out of it.
In any case as what's already been pointed out, you can synthesise this on an FPGA. FPGA development boards with a suitable sized FPGA (see the Pipistrello) can be had for less than $100.
No. That's not the point. If there were an alien world with the same conditions as earth (gravity, available substances, available energy) it is likely that while the actual species on this planet would be entirely different, they would be "life as we know it", in other words, similar biochemical processes.
Life but not as we know it means life based on fundamentally different biochemical processes, for example, silicon based instead of carbon based.
If you are holding out to the public a service of baking cakes, then you shouldn't be allowed to discriminate. If you want to be able to discriminate in who you bake cakes for, well, you're free to not do it as a business.
