I suspect that your implied "stupid JP Morgan spending all this money when you can do the same thing on GPUs" is a little naive. JP Morgan have experts too.
I am sorry that you have incorrectly inferred anything I may have implied.
My "back of the napkin calculations" were just that, calculations. They speak for themselves. Anything you choose to add to them, is your own creation.
Yes, my mistake as well, I should have said "integrated circuit" of which a microprocessor is an integrated circuit.
The idea of the integrated circuit was conceived by a radar scientist working for the Royal Radar Establishment of the British Ministry of Defence, Geoffrey W.A. Dummer (1909–2002). Dummer presented the idea to the public at the Symposium on Progress in Quality Electronic Components in Washington, D.C. on May 7, 1952.[4] He gave many symposia publicly to propagate his ideas, and unsuccessfully attempted to build such a circuit in 1956.
They appear to have launched 2 satellites so far, one called "Omid, or Hope," that "was sent into space as a "data-processing satellite project" and another called "Rasad-1, or Observation-1" which is "designed mainly for tracking the Earth’s resources from space. But the spacecraft, he said, “could also be used for low-resolution reconnaissance.”
Rasad-1 supposedly "circle[s] the Earth 15 times a day and should operate for two months." This was June 15, 2011. It quite possibly could still be operating, but if its not in a geostationary orbit, it's most likely not capable of hijacking a drone. Most likely an optical based sat.
The Omid was designed to gather data and test equipment, Reuters reported, and will circle Earth 14 times a day. Also not a geostationary sat. Hard to see how this one could be used either.
From Wikipedia
Most commercial jetliners have a service (or certificated) ceiling of about 42,000 feet (12,802 m)[citation needed] and some business jets about 51,000 feet (15,545 m).[2] While these airplanes' absolute ceiling is much higher than standard operational purposes, it is impossible to reach (because of the vertical speed asymptotically approaching zero) without afterburners or other devices temporarily increasing thrust.
While they [Iranian military] most likely have planes that can fly higher than 51,000 feet, and the drone supposedly has a service ceiling of 50,000 ft, this begs the question, what are the odds the Iranian military, flew above the drone, for long enough period of time, using an aircraft to hijack the the drone, or what are the odds, the non-geostationary satellites were used instead.
Seems pretty fishy to me. Not saying its impossible, just that its pushing the limits of plausibility, unless the drone had serious design flaws that made it extremely easy.
Using the source code is almost certainly against your contract, since it almost certainly becomes property of your employer. It doesn't take a lobotomy...
You are confusing copying the source code from the financial firm that you work for, and selling/giving/using it elsewhere, with... developing source code that has uses in multiple industries, of which the financial industry is just one of. The article even points out how the hardware developer also has oil industry customers. I would be willing to bet, the hardware comes with some software, an application framework, compilers, tools, OpenCL kernels, that are in fact shared by the financial industry, as well as, in this example, the oil industry. I know for a fact that the general field of "Signal Processing" is applicable in nearly every sector you care to name, which results in a production set of IP that does get utilized across multiple industries. In your words, "It doesn't take a lobotomy... "
In any case, I think relatively few people go into science from Wall Street. Once you're fed up with it, it's often too late to go into grad school. Instead, they probably get a job at a technology company
Technology companies don't use science ?
...No one in my PhD program was a stockbroker...
In case you aren't aware, a "stockbroker" is but one occupation in the financial industry. It's also one of the lowest status, high churn positions in the financial industry. Stockbroker is essentialy one step up from used car salesman, as that is what a stockbroker is, a salesman. There probably aren't alot of used car salesmen with PhDs either.
If you ask me, this attitude you have, is a direct result of the fact that you indeed were in a PhD program. Most people I've known in PhD programs look down on everyone who isn't also a PhD candidate, or doesn't already have a PhD, so I say unto you brother, check thy own head.
I quite often rant about the incompetence of my peers. But the only thing I can really do that is productive to combat the issue, is attempt to educate them. I too am flawed, and my knowledge incomplete, and in that respect, I'm just like everyone else.
When I said I support 'open source', let me give you a recent example.
The kid that works at the local gas-n-go said he was in college for computers, and that he would like to learn linux, but didn't have access to a computer with linux, because the only computer he had at home was his parents which had windows on it.
I returned an hour later, with a netbook I had lying around but wasn't using, that had a fresh install of linux on it, and gave it to him for free.
I think that was a non-greedy, socially responsible, resource re-distribution in order to avoid waste, open source supportive thing to do.
Well, open source is basically hippie communism. That doesn't mean it's not useful, or it should be banned.
A creator of a work should have the right to release it for all to use for free, or choose to recoup their investment via sales. It's their product, and their business, and their finances, who am I to mind their business for them ?
I'm sorry that guy was so selfish. But painting everyone in finance as a selfish greedy money lover who sells childrens organs in exchange for a new set of spinners on their Hummer, is a bit much. Alot like claiming everyone who uses open source, or is an open source enthusiast, is a hippie communist who eats dead skin from their big toe.
Perhaps it might renew your faith a little to know I work in Financial IT, and I use and support open source, and I'm not personally greedy.
It would be nice to live on a planet where money wasn't necessary. At this time however, that's not Earth.
I'm not really familiar with enough details of the Transmeta saga to really have an opinion on why they didn't take over the world.
The only thing that comes to mind, would be that they created an "x86 compatible" and that, when people were tasked with deciding what to standardize upon, Intel the real deal, or AMD the accepted competitor, Transmeta seemed like a bad choice. Anyone willing to deal with non-intel might have found ARM much more attractive. I dunno.
It's purely a guess on my part, and I'm sure I'll get blamed for being totally wrong. That said, I think I recall them selling off their technology, so it's not like their efforts were totally in vane. I would bet their ideas and IP have been absorbed by someone, somewhere, for something.
The article already pointed out, the hardware developer is a sub-contractor, and they also have customers in the oil industry. The rant I was responding to concerning "brain drain" I've seen on wired.com in FUD articles before.
I mean, the microprocessor itself started out as military technology, and it made its way into damn near every aspect of life. It's crazy to think wall street is sucking up all the science brainpower.
This form of SR enhancement has several important applications. It can be implemented on a wireless router or access point to increase its effective receiving range. Without SR, there would be data that were corrupted beyond repair because too much noise was introduced during transmission from a distant transmitter. With SR, this data can be reconstructed. This can also be used for the lawful interception of wireless transmissions. A receiver can be placed far enough away from the transceiver that is transmitting the data to be intercepted so that it is considered out of range, but by the use of SR it can retrieve the data.
And this begs the question, if the Iranians don't have their own comm satellites in space capable of doing this, or their own version of an AWAC that can fly higher than the drone was operating... who helped them ?
Question, though, is where was their spoofing equipment?
My guess, and although an educated one not necessarily accurate, is that their spoofing equipment would have to be a satellite in space, or an airplane flying above the drone.
The drones if I'm not mistaken, are designed with radiation absorbing coatings on their surface. The drones would have to receive their GPS signal from sats in space, located above the drone.
Any ground based jammer or spoofers signal, should in theory, be absorbed by the drones stealth surface coatings.
There is one potential theoretical discrepancy in the slashdot articles statements:
According to an Iranian engineer quoted in the article, 'By putting noise [jamming] on the communications, you force the bird into autopilot. This is where the bird loses its brain.'
The Iranian engineer is claiming all you have to do is broadcast "noise" to "jam" the communications link.
There is a well known mathematical technique called "Stochastic Resonance" whereby noise on a communications channel actually increases the reliability of the signal.
Nowhere did I mention clock speeds. I mentioned TFlops. Any TFlop numbers from the manufacturers, are most likely, best case theoretical hardware performance numbers, based on ALU * clock.
As for whether they are meaningful or meaningless, that depends on your point of view.
If you are a kid playing video games that only cares about frame rates, then perhaps it is meaningless to you.
If you are a developer looking at hardware, who can't yet benchmark the actual application, then it is as meaningful a measure as can be estimated.
I don't know any competent developer or systems integrator who thinks they will get 100% of the manufacturers advertised performance out of anything once they execute their own software. Please feel free to downgrade the manufacturers stated performance to suit your personal situation.
Slashdot Mirror
a bunch of idiots who don't realise the impact of what they are demanding
Are you referring to the people who think they should be allowed to copy and distribute content even if it is unlawful ?
See: The US vs China now.
A classic example of failing to protect ones means of production.
If there is no financial reward or incentive, no one will invest the time or money to create content.
A society that fails to protect its means of production, stops being productive.
What happened to the good ole days of the internet, where everyone was going to get filthy rich giving away stuff for free.
Sniff. I'm going to go and have a good nostalgic cry now.
I'd prefer continuous calculation via an analog based computer myself, but I'm not certain I could afford the water bill.

Don't forget to correlate any metrics collected internally, with your customers experience ratings.
Metrics collected internally without correlation can easily be gamed.
If you data mine the metrics against customer satisfaction, you'll see who is naughty and who is nice.

I'm not claiming drones use this method, just pointing out that "noise" != "jammed" when it comes to signals and communications.
3. when everything is leveraged 30-50x there is nothing you can do to provide stability that is not make-believe
Except of course, limit the amount of leverage allowed for any specific market or player, as they already do.
Whether the limits are being sanely applied or set at appropriate levels is another issue.
