If you use a 1 kHz ADC to measure a 1.1 kHz signal, what do you measure at 900 Hz?

No, you can pick up something higher than Nyquist, as long as you understand your sources of information and noise. It will alias down into the measurable range, and you can extract useful information from the alias. We have a system that operates up to 1 MHz using a 1.8 MHz ADC. When we know the signal is at 1 MHz, we extract the information at 800 kHz and use that.
What the GGP was talking about, though, was finding resonance on the bag where unique 30-Hz-width bands higher frequencies were being naturally modulated to baseband. If you had 100 points on the bag that each modulated a different frequency (30 Hz, 45 Hz, 90 Hz,
Except the ones for your keyboard and mouse, right? Except your keyboard broke, so just plug in this new one you got from Dell via NSAUSPS.
Man, what a pathetic troll style. Go to usenet and learn.

Pros: Today's article has more content than the usual Dice front page linkage. Great article if you're not a programmer but feel stymied by the wide assortment of languages out there. Although instead of hemming and hawing before making your first project you're better off listening to Winston Churchill and sticking your feet in the mud: "The maxim 'Nothing avails but perfection' may be spelt shorter -- 'Paralysis."
Cons: It barely scratches the surface of an incredibly deep topic with unlimited facets. And when one is considering investing potential technical debt into a technology, this probably wouldn't even suffice as an introduction let alone table of contents. Words spent on anecdotes ("In 2004, a coworker of mine referred to it as a 'toy language.'" like, lol no way bro!) could have been better spent on things like Lambdas in Java 8. Most interesting on the list is Erlang? Seems to be more of a random addition that could just as easily been Scala, Ruby, Groovy, Clojure, Dart -- whatever the cool hip thing it is we're playing with today but doesn't seem to quite pan out on a massive scale

The scam works better with a large purchase. Banks routinely deny transaction over some amount, forcing the retailer to call for an override code. Apparently the denial for "bad account" look identical to the one for "valid account, but that amount is high so give us a call, okay?"
If his card was denied for a $500 purchase, he'd need to convince the retailer that it was a bug in the system, not just a routine check for a large purchase.
> That's why Bitcoin needs regulation
Regulation doesn't stop scams, it merely makes them more creative. Let's regulate 'till only lawyers can own a business? Scams could be not prevented but undone, by total transparency and traceability, which is easier to implement than you think ("the books have no trace of transactions involving you and this thing? then you don't own it").
But, unfortunately, transparency would expose powerful people and their tricks, so the powerful people allow STASI-like spying and your children groped at the airport, so you rebel and seek comfort in privacy. Checkmate, you lose.
I am against BTC regulation because every time you earn something real or money, from bitcoin or whatever, you should put it in the tax form else you're being dishonest. BTC, like virtual game goodies, fall in this category IMHO.
I agree with the definition of pot as a gateway drug only because it is mostly harmless but illegal. Anyone taking it is already breaking the law, so why not do so with something else?
Having the law aligned with risk breaks the "gateway" argument; I agree with you that caffeine and alcohol etc. called gateways is ridiculous.
You look at trees and miss the forest. Bash deals with unix commands and tools, that means that if I need OOP i can do it in the scripting language of choice, which comes in a no strings attached license. It also means that a one liner can produce a mastered standard video dvd with a transcoded and trimmed video clip.
Yeah, I'm about to cancel as well. What's left on my list isn't awesome, and I can get a lot from the local libraries if I care that much.
Amish?
From the article, it sounds like CVUSD isn't an independent organization. The school districts where you live might be structured differently, so this might not be apparent to you.
In Texas, school districts are independent entities (ISDs) with their own taxing authority. The ISD owns the land and runs the schools. Board members are elected.
In Louisiana, where I lived for a while a long time ago, the parishes run the schools. There's a school board, whose members are IIRC appointed by the county commissioners, good ol' boy style. The schools have no tax authority and have to go to the parish for money or infrastructure requests.
It sounds like California organizes school districts more like the latter than the former, though a given county might have multiple districts instead of just one as in Louisiana parishes. The article describes the county limiting bandwidth use by CVUSD, something impossible to happen in Texas as the county has no authority over the ISD.
Likewise, and to your point, the article says that the county encouraged CVUSD to deploy the iPads, and from that CVUSD assumed the county had enough bandwidth to manage this. I guess that means the county is the district's ISP, and the district isn't allowed to change ISPs or contract with a private ISP. And the county IT maybe didn't know the district was going to do this, so they couldn't point it out and try to get a bigger pipe at that level. So they didn't see the problem because bureaucracy.
Parents being more involved in their kids' education is the educational silver bullet. If this is what it takes to make that possible in this district, so be it.
