Most people who charge at home, charge at night. So, without storage, solar panels don't help.

That's idiotic nonsense. Most people who charge their electric car at home, switch to peak/off-peak billing with their electric company. That means electricity used before midnight is insanely expensive, but solar panels can offset most of that daytime demand. And after midnight you can charge your car for a pittance.

Facebook has to change their posting guidelines to allow what's become "normal" political speech?

Right-wing political speech becomes less extreme every year. What Trump has said, while baseless and unsupported, is far less offensive than what we've previously seen from them.

"The gay community has infiltrated the very centers of power in every area across this country, and they wield extreme power⦠That agenda is the greatest threat to our freedom that we face today." -Senator Tom Coburn (R-OK)

âoeBlacks Bought A Lot Of Propaganda On The Liberal Plantation.â -Pat Buchanan (R-Nixon/Regan administrations)

"We have a high percentage of blacks in prison, and thatâ(TM)s tragic, but are they in prison just because they are black or because they donâ(TM)t want to study as hard in school? Iâ(TM)ve taught school, and I saw a lot of people of color who didnâ(TM)t study hard because they said the government would take care of them." -Sally Kern (R-OK)

"Yes black lives matter. The best way to end the slaughter of young black men is to take guns away from blacks as they are the main killers." -Randy Pullen (R-RNC Treasurer)

[Chris Mapp (R-TX)] stood by his comments, made during an editorial board meeting with the Dallas Morning News, that âoe'wetbacks' should be shot by ranchers and that President Barack Obama is a 'socialist son of a bitch.'â

Verizon, Sprint, and U.S. Cellular still maintain sizable CDMA infrastructure. They cannot use Intel's gsm-only modem.

Where in my comment did I mention any of them, let alone suggesting they should get one or the other.

Comment The issue isn't (just) speed - it's (also) range. (Score 1) 44

LTE is already pretty darn fast, so losing a little performance isn't going to make that big of a deal. It's not as if you can torrent to your hearts content without killing your cell phone bill.

The issue isn't just speed. It's also range.

At any given speed, the Qualcom can support it at substantially lower signal levels. 6ish dB in a lot of cases, a bit less in some, enormously more in others.

Look at the graphs in TFA. In addition to some specific pathologies that penalize the Intel chip farther, the bulk of the graph has the drop off looking similar but with the Qualcom shfited 5 or 6 dB to the right. (Those squares are 5 dB wide.)

6 dB is four times the effective signal strength, which corresponds to twice the range. That maps into four times the area served at that speed from a single cell tower (important in sparsely-served areas), deeper penetration into buildings and the like (in more heavily-covered areas). It can also map into more data pushed before a given area and channel allocation's bandwidth is saturated. 3 dB corresponds to twice the effective signal strength, 1.4ish times the radius, twice the area served.

If the modems were equivalent and the problem just the layout of the board and antenna, you'd expect the two curves to be the same shape but just offset. The shape is substantially different, so (board issues or not) something else is going on.

My guess is Apple is willing to turn a blind eye to that for the "1st gen" product and use the new revenue as a carrot to get Intel to direct its engineering efforts to the features that Apple wants, probably stuff like CDMA for example.

If Apple knew the Intel chipset was inferior and chose to sell it anyway, why is there no rhyme or reason to which of the models each of the carriers use? Surely the 2nd rate one would only go to carriers who want cheaper phones in exchange for compromised performance? Instead T-Mobile and AT&T both sell the Intel chipset version. Meanwhile, the cut-rate MVNO services of those same carriers, like MetroPCS and Cricket are getting the (better?) Qualcomm chipset.

As others have shot-down your other claims, I don't see that anything you've posted makes any sense...

Comment Pretty spammy (Score 1) 2

I have to agree with the mods, your submissions look awfully bad.

Stories without a sci/tech angle don't belong here, and most of yours have none. Your submissions are a lot of rumour-mill crap, full of words like "appears", "alleged" and "supposed", lousy sources like near-tabloid publications, etc.

Comment REALLY? (Score 5, Insightful) 209

The crime is making orders with the intent to cancel before being fulfilled. ... The intent to cancel, in order to create a false market perception, is the crime. ... a pattern of cancelled-while-unfulfilled orders, combined with other orders that profit from the market perception that the unfulfilled orders create, is a very clear establishment of such intent.

Is it also an establishment of intent if you (as a large financial firm) deploy, in actual trading on real markets with real money, an algorithm that exhibits such behavior? If, in addition, you KEEP it deployed even after its behavior is noticed and complained about in public media of the sort likely to be read by trading professionals?

And it is something that the traders at Goldman Sachs can make a fortune without doing.

But it's something that they can make a BIGGER fortune by DOING. And something that can count toward the rise of individuals and groups through the corporate ladder and pay scale.

While don't recall if G.S. was specifically one of the organizations complained about (and am not going to spend the time right now digging through archives to check), I DO recall com"plaints about high-speed traders taking advantage of the cancellation features of the online market engines in just this way.

One of the advantages of shaving milliseconds off the communication delays and algorithms that was specifically mentioned (once the pattern was observed) was the ability to send an order and a cancellation in rapid enough succession that it could not be pounced on (and thus didn't really risk money), sending price signals that tricked competing, slightly less high-speed or well-tuned, algorithms into making other bad trades from which their operators lost and the perpetrators gained.

Hillary was trumpeting "But Russia!" the day of the leak, before any investigation could possibly have taken place.

Trump does the same thing all the damn time, and he uses his rush to judgement as proof of how awesome he is.


If you're going for a Hillary conspiracy on that same thin premise, I suppose we'd have to say Trump mush have had advanced knowledge of the NYC bombing...

California is one of the states that gets raped on taxes by the federal government; our income taxes go to pay for stuff in other states that we can't afford

No, California ends up about even, getting slightly more dollars back than they pay out to the fed.

The state getting screwed the worst seems to be Minnesota, although Connecticut, Jersey, Colorado and Boston are way up there, too. Note that most western states are getting more back from the fed than they pay out.
