^calculating the energy required to accelerate a 2 ton object to orbital velocities in under 100 yards is left as an exercise for the reader.

it's probably on the order of the entire consumption of energy of the planet for one hour, condensed into less than 1 millisecond

Comment Re:Is USB really better? (Score 1) 543

Personally I think it's more along the lines that the USB-micro connectors don't last anywhere near as long. The connector on the phone seems to be ok, it's the connector on the cable that plugs into it that keeps losing rigidity and starts wiggling out if I pick the phone up after have plugged it in for charging for the night.
I can't imagine what would happen if they put one of those on the bottom.

The EU is a bunch of clowns that couldn't figure out why a unified currency with differentiated deficit spending was a recipe for disaster. The last thing I would expect them to be an expert on is device desgin.

Comment Re:It's not iTunes or Apple, it's RIAA (Score 1) 570

It's similar to the people who really, really want to waste USD $150 on a pair of Air Jordans. Most of them aren't going to buy them for playing basketball, they buy them because of the brand name and because of the perception that it will somehow make them cooler.

Very much the same thing when it comes to Apple products. Most of the people buying them don't understand what the specs, features and limitations mean for them. The only thing they know is the brand and the belief that it will somehow make them hip.

that's no perception, that's reality. We refused to sell out (or "buy out" I suppose), so we are nerdy and uncooler.

If the government decides it's not in the public interest they can stop it. At least they should tax it so as to extract the maximum revenue. E.g. 0.1% on every transaction, waived if you hold the instrument more than 10 minutes.

Bro, that's not how government works.
Government stops things that it perceives are not in THEIR interest.
As long as they keep getting bigger campaign contributions from the people making billions on HFT than from the small guy looking to be protected from HFT, it will continue to exist.

Also, a simple tax wouldn't be enough, look into the CFDs created to get around the UK's stamp tax (tax on stock transactions).
It would be passed as a gesture to the small guy while the real game is allowed to continue.
I'm not really sure why the SEC hasn't banned HFT yet.

If you're saying that arbitrage should be illegal, you have no idea what you're saying.

obviously you have no idea how to read, because that's not what he said.

"Just got a better offer elsewhere" "obliged to hold two short positions"
No. It's easy to write the algorithm around this. That's why only the worst of the worst (KNIGHT) lose at this game.

HFT is theft and is antagonistic towards the long term investor.

Comment enough to push IBM around (Score 1) 443

Ha, right.

It's clearly enough to push IBM around.
IBM is not a small cap.
This is antagonistic towards long term investors. Some guys had trailing stops and were shaken lose by bending the system. Sorry, but that's stealing to the tune of (volume * range/2).
IE, a few million shares in volume * (196.50-195.00)/2
so 2,000,000 * 0.75, or $1.5m.

The only reason this hasn't been criminalized yet is the public has no idea what's going on, and the politicians are receiving campaign contributions from the guys benefiting from HFTs.

Comment Stop lying, it's bad for the individual (Score 1) 443

the profit in HFT comes from exposing those who cannot protect themselves to risk via liquidity.
Long term investors have precisely zero interest in microsecond liquidity. It means their fortune can be lost without a chance of recovery when the markets go haywire, such as on May 6th 2010:

Tell me, what use is this kind of behavior to the market?
That's IBM we're talking about. This is of precisely zero value to the long term health of the market.
HFT needs to be banned, or microtransactions taxed a fraction of a cent per transaction. Not so much that it's not prohibitive to meet the market if it really needs the liquidity, but enough to protect the "little guy".

I've found watching great for grasping concepts, but you definitely need the homework for doing the actual work. Understanding recursion when you look at code, and remembering how to write it yourself, are completely different. Remember back in college you look over the study sheet and it says "recursion" and you're "oh I understand that", but then you take the test and it tells you to write a recursive function operating on some linked list or something and you have to waste 28 minutes hacking your way through it because it's the first time you've actually sat down to try it.
