The thing that happened is RTL-SDR, which is _not_ the name of a product but refers to the _use_ of a mass-market TV receiver USB device that happened to have a raw IQ signal mode in the hardware (RTL2832U chip). This being so cheap ($15-20) lots and lots of people jumped on it and this created a lot of interest in SDR in general.

I don't have a good overview to recommend you, but for ‘what kind of signals…’ I do recommend grabbing a RTL-SDR device, and just reading about how to use it should give you lots of pointers into the rest of the SDR world.
I know BT where we're talking about testing it on plusnet customers, didn't know they rolled it out to their whole network.
Everything has pro and cons. Windmills have just a few cons like don't block the air space (bad for a few birds (but less bad than water power plans for fish), helicopters, planes) and some noise (but that's true for every powerplant technologies except photovoltaic panels).

The good thing windmills are very eco-friendly. Only water/hydro and photovoltaic/sun-energy falls in the very same category.

This is not charitable to the comment you replied to. That comment suggested that looking at what companies have had success with is a no-brainer, and you interred they were suggesting "jumping on the hype wagon without understanding deeply the original problem that they solve". Here, I'll quote:

> You'd be stupid to not look at what the best and most successful companies in the world are doing with their engineering teams and take note of it.

I think you're both saying the same thing. People should look at what others are doing, and analyze the suitability to their own use case. I think this is exactly what people do. I've never seen a tool choice postmortem that concluded, "well we only chose it for hype, and that was stupid". It's always a specific thing that you thought would work better than it did.

For example, I came away from a project quite burned by Angular 1.x. It wasn't that we chose it because of hype that it was a poor choice, it was that the directive system did not make it as easy to build modular components as initial prototypes suggested it would be. React was then interesting to us (though we never pursued it on that project), not because of upvotes on HN, but because it scratched that itch better.

I guess I just don't see this wild hype cycle that everyone complains about - I just see people trying to scratch itches they have, sometimes making the right choice, and sometimes making the wrong choice.

You seem to confuse 'cars with old technology' with 'old cars', though I am not sure how "cars with '50s technology" could have led to that confusion.

Anyway, these are not even close to being the same. I was talking about the fact that the new cars being sold had ancient technology.

These were not "feelings". I mean, they were selling cars with rigid axles that would screech when turning corners. My dad (who worked for both US and German carmakers) explained other details to me about the engines, about fit-and-finish etc., but it was also painfully obvious for a layperson like myself.

My parents were landlords when I was growing up and I thought about getting into it myself. When I was looking into it I think 8% was the ballpark ROI most landlords were shooting for.

Totally agree. These are what I call "pile on" articles: take a real example of problems at one person or company, and then use very lightly related examples to indict an entire industry or subpopulation.

I worry many of these jobs will be temporary. We're just ramping up production of turbines and other equipment. Installations will peak within the next (maybe) 10 years and from then there will be less and less demain as maintenance will be the only thing we will require.
"dx^2 is negligible" can be alternatively (rigorously) obtained in standard analysis/calculus in the following sequence:

0) Intermediate value theorem (continuous function with image between b and c must be such that there is x such that f(x)=d for d between b and c. This can be first proved where d=0 -- it's the method of bisection by nested intervals, really -- and then generalized)
0.5) The actual definition of derivatives known to everyone.
1) Rolle's theorem, i.e. the Intermediate Value Theorem on first derivatives (if something goes up and down then it must have a critical pont).
2) Mean Value Theorem (Rolle's theorem but rotated)
3) Taylor's theorem.

50kw is still an incredible amount of power to transmit wirelessly without cooking the target and anything that may pass between the power transmitter and the target. Go put an egg in your microwave and watch what 1kw does to it.

It would also almost certainly require line of sight and a directional antenna that can track the aircraft. Batteries could be used in the aircraft to at least land safely if there were a loss in power.

But currently we have trouble transmitting 5 watts across the 7mm gap between a wireless charger and a phone. 50kw over a distance of 1-300km is a very long way away.
It'd be good to see some comparisons, why this and not one of the other currently available systems? Why should I use this over, for example, Luigi?

What scale is this intended for?

Is it intended to nearly solve a simple problem over my 20TB of data on S3? Big complex graphs? Or more for transitioning a small local report system that's currently in three excel files into a tested python script?

There is, actually, one single instance I can think of where a custom memcpy would be better for an audio player than the compiler-provided memcpy. Some time ago Intel engineers advised that you should memcpy backwards on certain CPUs because it ended up being slightly faster. If you're copying a large enough buffer and running with tight enough latency (not sure how that would happen though), there's the very slight possibility that you might end up not copying the first new expected sample in time.

It's possible to make quite a nice living working F&B, a customer service job, in a tourist town. Don't just assume everyone working a role is beneath you and living some kind of shit existence.

Well, the CPU they added was probably far less than $1/each when bought in bulk, so if you were making a PCB with chips on it already, you might as well add an extra processing unit.
I have migraines and I use Hue to control temperature. I find the cooler the light (blue, white) the easier it is on my headaches, where the warmer (yellow, orange) light makes me feel like I'm squinting, or in a daze and not fully awake. With Hue I can change just the area of the house I'm in to cool white and my wife can have her yellow warm glow everywhere else.
By the way your Onboarding step-by-step wizard[1] is really awesome. I've used similar scripts on my sites before but they keep breaking because the users often click on some div or button (or due to mobile phones) not intended (they're only learning) and then wizard can't sync to the next step and the whole thing breaks :/

Is this happening on your site? If not, would appreciate some tips about coding it and how to handle exception cases where the wizard can't keep in sync or user click on unintended page elements.

One aspect of HTTPS is that using it more or less amounts to obtaining permission. Theoretically, a site can provide its own certificate. In practice, browsers will refuse the first request to connect to a site when the certificate is not from a pre-approved list of certificate providers.

While it is generally possible to receive a free certificate from a trusted provider today, that does not mean that things won't change in a month or a year or five years.
What was the reason?
(Cockroach Labs CTO) Yes, the commit identifiers sound like something we could use, as long as they're not tied too closely to pg's WAL LSNs. For us, the token would be a 96-bit hybrid logical timestamp, and we'd want semantics roughly similar to HTTP cookies (the server sends it back with the response, and then that client will include it on any future requests. With our current implementation the client would only need to send the token on new connections, but including room for it on a per-request basis seems like a good idea).

Also on the subject of the protocol, we've run into a need for a (server-initiated) ping message (https://github.com/cockroachdb/cockroach/pull/10188).

I live on the most populous hilltop in Hyden KY. Our only ISP caps at 1mb, and its not terribly reliable. Satellite is of course an option, but the expense is prohibitive if you use a lot of data.
Is broadband expensive or bad or unavailable? What about satellite internet? I live in Mississippi and broadband internet is affordable and available throughout the state and has been for years so I expected Kentucky to have the same or similar. Some places miles away from the nearest town in MS definitely don't have broadband.
> I try to treat service employees well, not because of some patronizing sense of responsibility, but because I empathize with their position.

That sounds like a patronizing sense of responsibility. I treat service employees the same as I treat everyone else I meet - like a person. Not because they're serving me food/coffee, or because I have some sort of empathy for their situation (I do, I worked retail for a long time), but because they're human beings just like me.

The only feeling that this post gave me is: "Get over it. If there was no HDD you would still be programming assembly."

If you don't want to bet on new technologies than don't. No harm done. It is like the startup world, you don't want to invest? Don't! You do want to? Do! Of course the people who take the risk have also the benefits of getting the early gains. most big digital companies took a bet on new technologies to be the first on market. Sure, it had to fit your needs, but who says hypes can't?
Good link. Nevertheless HTTPS/HTTP2/TLS/bcrypt/MD5/SHA-256/AES/etc need an upgrade/replacement to be ready for day X, so the internet isn't really prepared yet.

I agree that Europe is racist unfortunately however I recollect serious ghettos in New York. I stayed on a Jewish Street in Brooklyn and there were practically 90% orthodox Jews in the area who avoided me like the plague (I'm white)... I walked a few blocks south and I was the only white guy. The black people there were very friendly and helpful but I could tell my presence was a novelty. I've never seen anything like that in Europe. The other thing that I notice is that race is on the top of everyone's mind all the time in the states to the point that it is a serious problem even when it shouldn't be.

>water/hydro

As you suggest in your prior sentence, hydro is very disruptive environmentally in some cases. The Glen Canyon Dam (and the once proposed dams in the Grand Canyon) are particular cases in point. There's a general trend toward removing old dams in New England in part because of their environmental impact. Of course, small scale hydro like microturbines is far less disruptive but it generates far less power.

Instrument cables actually sound a bit different; their capacitance influences the frequency response. The price doesn't really influence that much, though. Very cheap cables can be noisy (which means that they are microphonic, i.e. generate voltages in response to being moved / dragged about).

1mb 'broadband' service, offered as DSL, runs about 90$ per month, and that's our only ISP. One could get satellite that's faster, but satellite internet also has low data caps, and the cost scales out of proportion. The terrain derails reliable wireless services, and the low population density rules it out anyway - folk are pretty far apart.
