That's the trouble with some of the algorithms that HFT shops are allowed to run in their boiler room datacenters. Some of these guys can only afford 80ms-400ms of time to create a decision, and that doesn't leave them much room to insert code that takes a 25,000-foot-view of their total order volume and determine if their order flow is making sense or not, dealing with 50,000 one-off situations (such as somebody dumping huge amounts of paper on the futures markets by accident)..
and so the quants who came up with the automation trading algorithms and the programmers who put their drawing-board ideas into software code can only put circuit breakers in their own code that are self-serving, but have no interest to put in any collars that stop the trades if it's clear that the trading is damaging the market.
It's really too late now. Retail investors have been bailing out and moving over to safe-havens and leaving the exchanges to hedgies and HFT shops to mutually-masturbate with each other trying to steal each others' money.
You can see the often-said argument that the Flash Crash caused Zero-Prints was due to insanely-low bid prices is not exactly accurate. Sure there was some crazy offers, but look at the trading volume.... it was all execution nonsense coming from the HFT trading systems that was flooding the markets with non-sensical orders.
I kind of wish the exchanges DIDNT reverse the trades. It would have wiped out more than 3/4ths of all the HFT shops and sent them packing. Now I won't even dare put any IRA/401(k) money in equities much less any in cash brokerage, unless it's a company with astronomical cash balances and pays a fat dividend--which is hardly nobody.
I won't invest in mutual funds anymore because there's no way a tired old fund manager can keep up with constantly-changing HFT strategy.
The pit where this drama went down was JUST the S&P 500 e-mini futures pit. Here's the tick by tick and audio of the pit boss having a heart attack over it. This was the pit where the fat-fingered trade happened. Actually, it wasn't exactly a fat-finger but a mistimed trade... it was supposed to take 5 hours to sell the futures off in small little bursts, but instead they "flooded the market with paper".
This spilled over into the REAL stock exchanges when the futures indexes all trended down, this cause the HFT guys (High Frequency Traders) who trade and/or watch the e-mini market to queue orders to start selling on the actual equity side, which already had shallow liquidity. This caused stocks to break through the 100, 150 and later the 200-day moving averages, which then triggered off the program selling.
NYSE at this point had already turned on their SLOWDOWN code which caused all the HFT computer systems to think that there was something wrong at the NYSE, so the order flow that wasn't going to NASDAQ and the tertiary exchanges to get the flood of sell orders.
Everybody who had collars on their stocks to limit-sell at 10% and greater lows then triggered off and a stampede to sell ensued and dropped some S&P500 stocks (like Accenture) to print $0.
The HFT guys were running to their servers and trying to shut everything down while the madness ensued.
So much for all these fancy high speed servers in New Jersey and Connecticut. All it has done is convince the retail investors to toss their money in Treasuries and forget about it.
Is this different than someone deciding to run a bash script that wipes their hard drive, as root?
So you can install an extension that's bad. Like you can open an e-mail attachment that's bad. Like you can open a programmable document that has a bad macro.
Seriously, where's the security concern? Don't install crap extensions and you won't have your passwords stolen through crap extensions. Easy enough?
There is an app for this and it's called Asterisk.
You can also do this with sipgate via Asterisk on any cell phone if you publish a sipgate number and route through to your cell and configure Asterisk do the filtering, which it can also intercept a whitelist/blacklist caller and then start playing games with them.
The cheap way of doing this is to let Google Voice be your answering machine, and change your voice message to "Hello? (4 second pause) Oh I'm sorry I'm not here." That is enough to trick most autodialers into routing your voicemail to a live operator, who then has the option of revealing who they are or hanging up and calling again. I don't accept blocked/800/877 and Unavailable caller ID. At least with Google Voice's translate feature I can bulk delete most of the crap voicemails without listening to them and if I did dump a call to VMX that was a legit caller I can read their voicemail and return it.
There are already drugs that inhibit CD4+T lymphocite binding in addition to drugs that stop reverse transcriptase against HIV RNA and yet STILL more drugs that inhibit the protein folding process HIV needs to change into a useful virion. Presuming this antibody does work, what then? Does at least cover HIV1 as well as HIV2?
Depending on where you put the nuke when it explodes, you could cause an EM burst and basically everything that's electric and electronic that you use, dies. It would be a long time before you would see electricity ever again.
You are NOT liable for debit fraud over $50 on your account, provided you notify the bank within 3 days of it occurring. The $50 exemption for banks is to incentivize you to report fraud quickly rather than waiting until the end of the statement cycle and looking at the paper, long after the fraudster has disappeared.
If your credit sucks too much to get a real credit card through a credit union---go get a secured credit card from people like Public Savings Bank or a credit union that offers secured credit cards. You put up a security deposit and that's your credit line. If you close the account, you get the deposit back. If you get the secured card through some banks like CapOne, etc---they may unsecure the card after a while and return your deposit, which means then you have an unsecured credit card with a credit line.
Nonetheless... good luck with some of these banks in getting NSF funds due to fraud reversed. Large banks generally do whatever they can to keep their fee income, including pissing you off to the point where you close your account and take all your business away. Large national and regional banks as a whole only get concerned if you're a large customer that has significant deposits; mostly because branch managers do get graded on retail stats like how many new accounts opened and products purchased, etc. Losing a big depositor makes weekly stats look ugly, so they will bend over to save you. They really don't care much about the depositor who can barely keep $1,000/£500 in the bank.
The same goes with lending products. Customers with excellent credit (which the banks checks periodically by doing soft pulls on the credit bureaus), revolve their accounts somewhat and generate lots of transaction volume are woo'd and if you call to cancel a card--you will get xfer'd to a "customer save" department... ALWAYS manned by native English speakers, where they try to save the account from closure. Contrast that with borrowers with mediocre credit, make only minimum payments, late-pay or don't use their accounts much at all, the bank is happy to see them go.
You should always use a credit card when making purchases because it's the bank's money on the line, not your own and if you detect fraud, you can ask for a chargeback. Chargebacks cause the merchant to get money wiped off their credit card remittances for the amount of the chargeback.
I did a chargeback once when a kid at Starbucks rang up my coffee, twice, on two tickets. I only got one receipt but when I checked my credit card statement... two transactions for the same money for the same day hit my account. I clicked on the charge and clicked "Contest charge" and explained why I thought it was wrong. The next day the charge was gone off my statement, and that Starbucks store got $4.96 wiped off their credit card remittances for charging me twice, which leaves it to their store manager to search their records to find out why they got a chargeback and who caused it to happen, etc.
You can't easily do chargebacks with debit cards because you have to fight your bank. With credit cards it's easy, because Visa/MC/Amex/DISC build purchase protection into their credit card contracts.
I'd like to see this same experiment done on Philadelphia's extensive transit system (SEPTA). Considering that it's pretty easy for the homeless to urinate just about everyone in the system and go unpunished for it... I bet photography is also on the list of least concerns.
You're not going to see any speed gain from *just* switching to C++ from C. A direct translation of code from C to some other language invariably never accomplishes this. The compilation of Compiz will also be slower if it was just a language change, anyway.***
*** Unless the authors also did a major refactor and performance enhancement job while they were sifting through the code, which is what I always strive to do when I have to refactor an entire project from scratch, but in a time crunch or to get new features out quickly... might not be able to do.
I haven't finished RTFA (it's in another tab), but I would have thought if massive performance changes were being made to the code---surely that would be at the forefront of any refactor announcement. Most developers love to parade their performance boosting efforts at release time.
I would not expect Compiz 0.10 (or 1.0) to be much different than previous releases except for already announced feature-change that's being baked into the new code.
The language and dependency changes aside, how much do you want to bet there will be problems in every package distro?
After 2 and a half years of getting Compiz sorted in SuSE, RH, Slackware so you have a 50% or better chance of it working out of the box when you install a distro, not having to dig through massive tweaking to get it operating... I'm expecting a step or two backwards in the "installability" department for a while.
If you got an iPhone or a Driod, you can get WiFi-Fo-Fum. Go into your router settings and make sure you're broadcasting your SSID and lock on to it on the smartphone. I've found dead spots in my rowhome (3 stories) where there were just Faraday-like dead spots in my house and one was near my basement PC. Repositioned the antenna and all was back to normal. I also can't walk near the spots when I'm using my mobile or the calls cut off, too.
The latest edition to Pennsylvania's vast natural gas reserves, the Mercellus Shale find, is our only hope in this state to recover from de-investment since the steel industry was obliterated in the 1970s, and the coal industry before that.
Since NatGas prices are now trading at obscenely low levels, I'm hoping for more expansion (and driller taxation) in my state to at least make up somewhat for 30 years of economic decline, and the expectation is that NatGas prices now have nowhere to go but back up after perhaps another 12-20 month plateau until more coal-fired power plants are retired and gas-generated electricity expands.
Home consumption of natural gas in Pennsylvania is starting to expand after years of decline. Most PA electric companies will be allowed to jack up rates starting in 2011, which means any homeowner who moved off gas or oil heat to cheap and ineffecient forced-air electric heating elements to save money will now be royally screwed.
There's a lot of local companies around the Philadelphia area who are making a mint converting newer houses off electric heating back on to Natural Gas and those who are giving up oil heat are picking forced-air gas furnaces instead.
I am soon to buy a new home, and not only does my water heater and my furnace run off gas, but I will be switching my 240V electric clothes dryer (120V powers the motor, 240V goes to the heating element) to a low power 120V electric/gas dryer. Gas clothes dryers also dry your clothes quicker than all-electric models do with a more even application of heat.
The problem wasn't the NYSE. The problem was that when the NYSE decided to execute trading delays, the other markets replied "the computer sez no" and kept on trading at high speed. Because there weren't enough buyers at the time to satisfy all the selling, all the market sellers saw their prices plummet because the computers were programmed to find a buyer no matter what the price, as long as the transaction would clear.
So... what's the problem? If you picked up Accenture at a penny a share you should be fuckin' lucky. I wouldn't shiv that stock off to a homeless man for a nickel.
I still opt to get paper statements from Comcast because I love killing trees and it takes them longer to get my money. But print or online, if they are going to cap usage and nag users about their useage, why not print the bar graph on the top of Page 1 on the PDF version and the print version of the bill?
My electric company does it. My gas company does it. My water utility does it. Comcast is just another utility bill really. Print the stupid usage on the bill and call it a day.
Why do I need to waste 15 minutes of my life figuring out another "tool" on their site when I have better things to do with my time? I read every bill I get and pay them religiously. If I saw that I went crazy with my bandwidth, I'll check my LAN and WLAN to see what's up---maybe someone cracked my wireless key and is doing a drive-by. Maybe I'm downloading way too much porn than I thought I should... who cares?
