Utter nonsense. HFT is not a scam. It's not the cause of the recession (depression - whatever). It makes a small profit doing what people would otherwise do, only faster. HFT is also inevitable. As soon as the exchanges were automated and networked some kind of algorithmic trading appeared. It caused a reduction in the bid ask spread and an increase in liquidity. These things are considered by experts to be beneficial. When I say "small" profit - it's a small amount compared to the size of the actual trades that take place. Often a small fraction of a cent per share, for example. Much lower than your broker charges.
Nope. He hacked (read "tinkered with") the hardware bought and owned outright. If there is a way of modifying a piece of hardware such that it allows unauthorized access to an external network (the playstation store, etc.), then that network is faulty. Do you suppose I can hack my PC to access MSN without authority? Beyond that point, though, there is another: He never accessed PSN, and thus the store - at least according to his court submissions. He couldn't use "having not agreed to any license terms" as a defense otherwise. So he couldn't have known PSN and services were so retarded. The rumor is that Sony probably discovered that there was a fatal flaw in the design of the Playstation Store and Qriosity and had to start from scratch with major components. That's not the fault of GeoHot.
I think he's trying to say that none of your comment was true. If so, I'd agree. I could not possibly admit that Christianity as a whole is more tolerant. Neither could I admit that it's no longer a dominant force in governments. Perhaps *some* governments. Certainly not the US where being Christian is a platform. It's unimaginable that a non-Christian could become President. OK - it *is* less prone to violence.
Such crap. Microsoft has a financial headquarter in Ireland, so they can pay less taxes. They hardly pay the US anything. Increasing taxes too far reduces the net tax revenue.
Nope. I am saying it's beneficial. High frequency trading is beneficial to investors, and the market place as a whole. I've watched as the HFT companies pull out, and the spreads widen drastically, and volume falls precipitously. As an investor, where do you go if you need to sell a block of stock? Right now your broker will try to find a buyer, but the best price will be found on one of the exchanges. So when there is no electronic market making and spreads are 25c, you think you'll be better off? Stocks flow easily right now because it's so cheap to trade them. And that's almost entirely due to HFT. It's natural competition - using a speed advantage to gain a small price edge. Some of these trades make a sub penny profit! How does that harm an individual, who is paying his or her broker a percentage??
I actually work for one of the fastest HFT companies, and worked for a different one prior. They don't use inside information. Indeed it's impossible. Neither company are brokers - so they only have access to public information. These companies also frequently come under scrutiny, because the order and trade volumes can be high, so if any illicit activity were taking place, the SEC etc. would take action. Indeed, I've seen a fine handed out for a minor order marking mistake - so it's clear they take their regulations seriously. In fact, the SEC is much more interested in protecting the investor, and the market place as a whole. Many of the regulation relate to customer handling, and market manipulation. Any activity that looks like manipulation is investigated. An additional per trade tax idea was floated around, but experts convinced congress that it would lead to a reduction in liquidity, and a widening of bid ask spreads - which translates to a higher cost to investors. The experts are right. Highly traded stocks now have a penny spread, but before electronic trading they were at 25c. Add a 10c tax and you'd be talking about an effective 45c spread and a horriby sluggish market. The rest of the world would be much more attractive to all traders, and the US would be hit pretty hard. Secret does not imply illicit.
Sadly, the DMCA doesn't only cover copying - it also has significant anti-circumvention provisions. Both copying protection and access protection are covered. Some info may be found here: http://copyright.gov/legislation/dmca.pdf Here is title 17, which contains the copyright code: http://www.copyright.gov/title17
My gut reaction is to have the law assume fair use, and make copy protection a limited exception. You can sell licenses, but only in limited circumstances. Then the profiteer has the cost of trying to recover moneys from those they accuse of infringing. Copyright was supposed to be a limited monopoly, but it's gone way beyond its original intent. In my opinion, far too far. But that's my gut, my head may have a different opinion, and they're both subject to change.:)
Commutativity is preserved by using Math.abs((a-b)/(a+b)) or test both Math.abs((a-b)/a) and Math.abs((b-a)/b).
I don't think you are correct about two numbers not being "nearly equal" when they are both close to zero, but with opposite signs. The function returns "true" in this case, no? Are you suggesting this is undesirable? I could see for some use cases that property might be undesirable, but if that's what you meant it wasn't clear. Certainly that property is desirable for some applications.
I have kids that range from age 7 thru 17. We have Big Brain Academy. 1. Many of the tasks are very similar to homework questions. 2. We find the games entertaining.
I have no doubt that practising this stuff is helping my youngest in school. I've also noticed an improvement in our ability in these specific tasks. Is it so easy to discount the idea that these skills won't help other areas?
In what way can it be said to exist if it has no physical manifestation and has no measurable effect on the world, and can not be detected in any way whatsoever?
This "90% of the universe" was assumed to be there and isn't contrary to dark matter.
If it were proven that these galaxies did not, in fact, exist; well that would contradict much of known physics.

In my perfect world that would not be fair use. If kindergarteners sell tickets and perform, I wouldn't place it under fair use.
I assumed no such thing. Just stating the way I think things should be.
IMHO copying sheet music for in-class use should be fair use and should be exempted from licencing requirements.

No, it doesn't.
