Pardon my ignorance, as I'm not a network-admin type in the least, but would there be something wrong with using plain gigabit ethernet switches with an optical module (or something to the effect, not sure of the terminology). Is there any future use for the system that would be hindered by using plain switches instead?
I remember seeing articles about the use of holographic storage medium with 500 GB potential http://www.crn.com/news/storage/217200230/ge-unveils-500-gb-holographic-disc-storage-technology.htm . Don't know if it will ever come around, but it would be a possible physical media source (assuming that the read speeds were fast enough)
He says demand has increased 1,000 percent this year compared to last—itself a 1,000 percent increase over the year before."
So they went from 1 person, to 10 people, to 100 people?
don't broadcast your location to the rest of the world with your cellphone.
You don't have to necessarily. Signal strength and triangulation can give a rough idea of someone's location.
If the hum is generated from imbalances between the generation and consumption of power, is there any difference in the hum across the entire grid? Or do the transmission lines transmit the current evenly across the entire grid to the point where the hum in one area is indistinguishable from a spot clear across the country?
If it is likely to cost 3 times the current amount, shouldn't the title read: "Roughly $9,000 car coming to US at some point"
I might be mistaken, but it seems like the driving profile of the EV user would matter as well. Consider someone who works in the middle of a metropolitan area, and lives in a small neighborhood ~10-15 miles away. If they spend the majority of their driving time in rush hour traffic, it seems like EVs would be more efficient because they don't waste as much energy when idle/stop-and-go traffic (ignoring things like A/C). Even if they were charged with power from a coal plant, they might still be more efficient. While city/highway EPA numbers work as an overall "average", the benefits of EVs would be greater for this type of driver.
The commands can be keyed in using touchtones or even using the human voice.
To bad i'm very much tone deaf
No, instead what's going on is someone put out a big pre-order for Microsoft stock and so the HFT guys are buying stocks at a lower price than that only to turn over and dump them almost instantly as the order actually comes through netting fractions of a penny.
Actually, this isn't what is going on. Their access to the trade flow doesn't let them see the market book (what would record the "pre-order"). Instead, they are looking for patterns in the limit orders representing large institutional traders trying to unwind their position (think mutual funds). Since these big players can't place an sell order for 10,000 shares, they break them up into smaller chunks using their own sell algos. If a HFT can identify these trades, they can jump in and buy ahead of the fund and sell to them. They are simply trying to outwit the other institutional fund's trading algorithms.
Disclaimer: I'm a finance doctoral student, and one of my colleagues actually does research into HFT using proprietary data
