After being so upset with his cheating class, why does the professor offer a large time period to re-take the test? It seems like he is baiting the students to cheat again. Can't he set it during a normal class period where everyone takes it at once?

You act like TSA agents came up with the idea to grope and body scan everyone in the airport. This is a huge pain the in ass for them, and they know that it poses a health risk for themselves. However, this is their job, and they are carrying out orders from their superiors. So there's no reason to make snide remarks to the agents.

"There is no point having the optimal colo between TSE and NYSE because they have no overlapping hours nor do they have anything that trades on both and is fungible."

There is tremendous overlap amongst various stock exchanges, OTC's, dark pools (12% of US trading), and of course there's Forex which is 24/7.

Quantitative trading companies are spending more and more money to trade faster, because the barrier to entry continues to plummet. For example, they used to install software programs on computers, now they actually hard-wire programs directly to motherboards to shorten the execution time. As the article mentioned, trading firms are investing heavily into expensive fiber optic lines instead of traditional internet. For these reasons and many more, the fraction of a penny that each trade earns them also continues to grow smaller as the arbitrage that they trade on grows smaller because every firm is investing into the same expensive strategies.

Automated trading is almost to an equilibrium, where the costs will begin outweighing the profits.

Not only do the supporters not vote, but they have very little political power nor do they provide monetary support.

The users are not at fault here. Even a SSH or VPN will leave them vulnerable to attacks. Companies (Facebook, Twitter, etc.) have to increase their own security, because they are the only ones that can fix this problem.

It's all relative.

Let's say I go to the mechanic with a light on in the dashboard, and he'll immediately notice the gas cap isn't tightly secured so it set off a car sensor. He probably went back to his mechanic friends, told them the story, and everyone laughed.

The computer and everything about it is our profession/hobby/passion and that is the main reason we know so much more than everyone else about it.

An IPO for Facebook would mean losing all of their top engineers who are hanging around until they can cash out. Everyone will leave for the next hot startup and to work on their own projects. Zuck is smart for dragging the process out.

Three points:

1. Sounds like UberCab should look into licensing out their platform to existing cab companies. It would mean lower margins, but they can quickly scale throughout the US and beyond much faster.

2. UberCab's blog post is arrogant. Did they really think they can avoid paying expensive licensing fees because they are using black cars instead of yellow cabs? Taxi licenses are very expensive and a lucrative revenue source for every major city. A taxi seat can cost as much as 1 million to purchase in NYC, and I know other cities such as SF and LV are not much cheaper due to the fixed number of licenses. I can only imagine the outrage of other cab drivers losing work to cheaper services (i.e. UberCab) because they are not paying licensing fees.

3. UberCab can easily recover albeit at lower margins. They need aggressive biz dev to quickly secure licenses. I hope they can continue to disrupt city transportation.

What are your thoughts the two founders being identical twin brothers?
