>Generics are used to defer type setting from compile time to run time, allowing for flexible, yet type-safe constructs.

No. Some languages implement it that way, but nothing about the concept involves moving anything to run time. In languages with reasonable type systems, there is no run time involvement at all.

As an interviewer, I don't know you. What I do know is that there are a lot of whining "the grass is always greener" types that find fault in everything and don't realize the world isn't perfect.

If you say a single negative thing about your past employer i will immediately be fearful that you are that type of person. In fact, when I interview developers I specifically try to get them to say something negative about their current job. I do this because whiners are so unbelievably destructive to an organization that I never want to hire one.

Now I ask you... What positive purpose does it serve to bad mouth your previous employer to a prospective employer?

Investments almost work on a loss leader model - while there is still decisions made on who to invest in (some VC firms/investors/angels making wiser decisions than others), they are still banking on the small percentage of those investments actually making a return on investment. This return covers the failed investments that they might eventually write off.

The general rule is 1/3rd of investments will fail, 1/3rd of investments will under perform and 1/3rd will meet expectations - and to put that in to a better perspective, "expectations" should be read as a 5x to 10x return on investment. A better firm might be able to skew that more to the successful side, while another firm might be more on the failure side.

I don't think the money will "run out" - but the better firms (think USV, Sequoia, Accel, etc) will continue having the experience in finding successful startups and the smaller firms might just not see the return on interest and exit the game.

I get why the need to always be one step ahead pushed trading firms to automation. Still, for some reason, this makes me incredibly sad. Maybe it's because I don't fully understand how the world and the economy work. Why does it have to be this way?
In addition to making your opinion heard to your senator and representative I would recommend using strong, vetted and open source encryption whenever possible. Whisper Systems is a good place to start for mobile security on Android.

TextSecure and RedPhone will secure the content of your communications, but I'm not sure they will prevent the "metadata" from being captured (who called who, for how long, ect).

The biggest hurdle to me effectively using these tools is convincing others to use them. Many people seem eerily not bothered by being spied on by their own government or private companies. It's a strange world...

I think the real lesson is that humans aren't always (or even often) rational. A logical argument that assumes humans are always rational is incorrect. But if you have a good model of human thought and interaction that includes all the irrational parts, using logic to analyze it can work great.

He didn't say nor have I ever heard a libertarian claim they wanted no government. I believe that's a different ideology.
I think there's an easy answer. He's heard of people living to 100. He's human, thus overly optimistic, and assumes he'll live until 100. I don't think that can be called a lie. Just a flaw in human logic.

I think most of your clues are inconclusive, but I don't care one way or another. I'm just going to sit back, relax and hope that the emotions I feel from this blog are less real than the actual blog. Because that is what a story is, and one way or another this man is telling a story.
My mistake. I had been poking around the raspbmc site and saw that he was at King's College - theres also a Kings College in London Canada and I jumped to conclusions.

He said on his twitter

>My son shows me how to use tweeter from my phone. Tweeter suggests me to follow a lot of journalists. Funny !
Far too often, logical fallacies are invoked in order to run away from an argument.

I think this is the core point: the fallacy-lobbers are often looking to dismiss the entire conversation rather than trying to participate in it. There's no counter-argument; instead, the message is, "You're too dumb to bother with." That may sometimes be true, but it's never conducive to enlightening discussion.
What does it matter if this were fake? It's not like they're asking us to donate a tithe.
The second main point: with declining volatility, there is less space for HFT strategies to profit.

What I didn't see in the article was an explicit discussion of transaction costs. Transaction tax would increase those costs, but was part of the decline because transaction costs have already gone up?
Arguments are about core issues, not peripheral issues.

The only way to convict your opponent is on their ground, not your own.

Taking an argument seriously, as if it were the best representation of itself, is the only way to defeat it.

In order to truly disagree, you must discover how much you already agree.

Could there be some miracle cure for aging in the next 20 years? Probably not but maybe. Will it help the person who is 78 when it is discovered? Almost definitely not - the aging damage has been done!
Nanex is a company that intrigues me immensely. I follow Scott (their founder, I think) on twitter and I wish I understood even a small percentage of what they produce on a daily basis. The stock market in general is something I wish I understood more of. Can anyone recommend some reading material?
One of the prevailing theories from http://www.nanex.net/ is that when Knight went live they also put their order simulator live as well.

The thinking behind this theory was that a simulator would keep adding liquidity to a fake market for testing a market making algo.

During the day that Knight lost their pants nanex saw that while their algo was taking liquidity someone else was constantly providing it, ie the bid ask spread didn't really open up that much and the price held relatively flat.

This meant that someone else was constantly adding liquidity that Knight was taking away. The thinking was that Knights market simulator was the one sending out the live orders to add liquidity.

TL/DR Knight crossed themselves many many times in a few minutes.

So, there's a correlation between HFT and volatility. Yup.

Causation is hard though.

"Trading volumes in U.S. equities are around 6 billion shares a day, roughly where they were in 2006. Volatility, a measure of the extent to which a share’s price jumps around, is about half what it was a few years ago. By seeking out price disparities across assets and exchanges, speed traders ensure that when things do get out of whack, they’re quickly brought back into harmony."

There's been academic research that HFT market making dampens intraday volatility [1]

There have also been findings in the other direction [2].

I suspect to the extent you're talking about market making, the first version is true, but you almost never see it in articles like this. Maybe it makes for poor sensationalism.

That's not the point, and there are units which address those concerns. The point is, home automation is not "right around the corner", it's here today and it doesn't take a millionaire to have a smart home. The sticking point is not technology nor is it money, it's that people have realized they don't really want that.

I'm in Cole Valley too, and being in the shadow of Sutro causes all sorts of RF issues, especially on the southern half of the neighborhood. AT&T and Verizon are worthless, T-Mobile is barely usable, and the TV signals coming from Sutro pass overhead, while the mountain itself blocks NBC coming from the south. Even Monkeybrains has had trouble with Cole Valley.

I love the neighborhood, but the wireless situation sucks.

HFT basically involves an arbitrage. The more competition there is, the less profits are made. It's simply a case of the market becoming more efficient, so the arbitrage opportunity is gone.

Meanwhile, consumers of market makers (ie. normal investors) benefit from being able to make any trade in a split second, for very little cost. In the end, it still requires a human element.
These are good points, but, not computer science. These are HCI. Maybe a HCI course should be a required part of CS curricula. That can be debated. I don't see anything wrong with it.

You caught me: I've not hired a domain expert coder. But I've also not paid $120/hr for front-end coders. I over-paid for one guy who knew far less than I did- horrible coding practice, always thought he was farther along on the project than he really was (and wanted money), and, in fact, never got far enough to even understand the problem before I terminated the agreement.

For $120/hr the person isn't fiddling- they've done it before, probably have a personal library they can pull, and a basic shell of a website can be ready pretty quickly. Their time is almost entirely spent on the custom part of the site.
If you are told you have 30 days to live, you're much more likely to die tomorrow than someone expected to live another 60 years. The 30 days isn't an exact number, it's a guess, and whatever's expected to kill you in around 30 days might take a turn for the worse at any time. My grandmother died the day after the doctors said she had a few months to live.

Porn has a very long history and is pretty normal. Humans really, really love to make graphic depictions of sex. Before the internet there were magazines and VHS, and before that there were photos. (Go to any museum of sex and you'll see that Victorians weren't quite so Victorian.) Keep going back through history and it's pretty much always existed in some form with varying degrees of prevalence. [1]

If I were a parent I would have absolutely no problem with my kid accessing porn so long as they had a decent sex education. I don't want to essentially write the same comment twice, but I explain my position reasonably well elsewhere. [2]

There is a distinction between public and private places, but there are also grades of privacy. If I am in my own home, I expect that no one will be watching me. If I am on a podium in front of a crowd, I expect that everyone will be watching me. If I am walking in a public area, I expect that only people who know me will notice me. It is that last expectation that omnipresent cameras shatter.
I believe 13 years old would be just right.
Yes, that's the integral section of the article, but what it's really saying is that at least one component of this is the current cycle low in volatility and volume. This is a classic wall st shakeout when the best capitalized firms that make it through the down part of the cycle come back much stronger when their market returns because their competition closed up shop. They haven't scared everybody away, they're just suffering a market downturn in volatility and volume right now.

The robots win when people trade more and when prices move around more. When those conditions return, the robot party will be back on.
apparently there was a test component that took every order the model generated and copied the message 5 or 10 times - supposedly to stress test the system. Somehow this component was in production. Real orders were going out to the market and executions flowed back to an error account that was not being monitored. I imagine if you were monitoring the PnL you would have seen massive profits in the first few moments that the system went haywire - only to realize that you were simply just driving up the prices of your own positions...
From what I read about this crash the most important lesson was to have a kill switch. The biggest problem Knight Capital had was that they could not switch the system off quickly. It was roughly 45 minutes (according most accounts) between Knight realising something was wrong to ceasing trading.

That there was a bug in some code isn't surprising. That it was so hard to stop their trading is really surprising.

Useful only as a "worst-case" fearmongering. Any service/system with a substantial number of users is going to have horror stories. You can find horror stories, for example, of bedbugs and foul rooms for every major hotel chain with a quick search.

Of course, being cautious about who you let in your home should be common sense. You can't trust an automated website to do anything more than make the connection.
also - the changes were made on the same day NYSE's RLP program went live. so the guess is that these changes were made to handle RLP flow.

I remember reading about how Lebanon's cellular phone providers are deeply in bed with Hezbollah, as just one example. Likewise with the Taliban working in concert with AQ before 9/11.

My gut reaction is that I don't like this, but it's hard to argue that the U.S. is fighting an even bout with those who would enter the country and use its civil liberties to aid their terrorism planning.

Of course we expect that, the question is where to draw the line in areas where civil liberty directly conflicts with security.

Definitely: the EU, in particular, seems to be pretty inventive in their use of English, coming up with new words, novel grammatical constructions, and novel meanings for old words, and since so many of the documents are written by non-native English speakers, this inventions end up being assumed correct by other bureaucrats and re-used in subsequent writing, such that the EU has developed its own weird English pseudo-dialect.
