>in the past the big HFT's had a 20 millisecond window where they were allowed to see the market orders before anyone else

As far as I know, flash trading was an optional feature, designed to be used by those who wished to shop around their order in a somewhat private network, before sending it to the wider market.

> This was effectively legalised front running of the market

If you say flash orders were abused, I'll take your word for it, but it wasn't designed to be a way to front-run. Its purpose was actually to help.

I don't know why you've been down voted but this is exactly what I read yesterday in Dan Ariely's Predictably Irrational. A $2 aspirin worked better than a 50 cent one. That is to say, people who paid more for the exact same medicine were less likely to come back after a month for the same problem. It's actually crazy on how true his observations are, even on yourself.

It took me about three months to really adapt to a standing workspace. What I found interesting during the adaptation period was that when I needed a break, I would walk away from the desk and sit down, and that it was easier to continue to be productive during these breaks than it had been when my workspace was seated.

I'm not sure about which OCR you're talking about but I've tried ABBYY and because of the fractions ie top and bottom halves the thing craps out. Granted, if you get a single line problem it could easily be solved. Definitely there's the problem of application as well.

I live in Brighton and the vast majority of people I know use http://www.just-eat.co.uk/ which is basically an online wrapper for ordering takeaways. It covers loads of the local places and you usually get free delivery within a ~2 mile radius for orders over £8 or a ~£3 surcharge for delivery. You can order pretty much any kind of fast food from there, although the big companies (McDonalds, etc) don't deliver.

It's not arbitrary though. The point was to move away from the metaphor of moving the window around a document to just manipulating the document directly as you do in iOS. Granted it's not as obviously the right thing when touch is not involved, but it is the right thing.
The preferred syntax, which is more flexible and doesn't leak the loop variable, is to use generator expressions:

>>> x = ['1', '2', '3', '4', '5']
>>> y = list(int(i) for i in x)
>>> y
[1, 2, 3, 4, 5]

It also works for tuples:

>>> y = tuple(int(i) for i in x)
>>> y
(1, 2, 3, 4, 5)

And for dicts:

>>> y = dict((i, int(i)) for i in x)
>>> y
{'1': 1, '3': 3, '2': 2, '5': 5, '4': 4}

And if you want a lazily-evaluated generator:

>>> y = (int(i) for i in x)
>>> y
<generator object <genexpr> at 0xb7655eb4>

Also, as I mentioned before, generator expressions don't leak the loop variable:

>>> i = 42
>>> y = list(int(i) for i in x)
>>> i
42
>>> y = [int(i) for i in x]
>>> i
'5'

From the landing page of reCaptcha: "reCAPTCHA IS A FREE ANTI-BOT SERVICE THAT HELPS DIGITIZE BOOKS".

The "What is reCAPTCHA" explains the OCR process clearly and has the phrase "Currently, we are helping to digitize old editions of the New York Times and books from Google Books."

And if you click on the "HELP" link in a reCAPTCHA, it opens a small page with the instructions and a paragraph explain the OCR and a link to Learn More.

Your article's title should be: Captchas are sometimes so ridiculous, that they take 1 second longer to solve because you need to refresh them which is besides the point that is that we are due for a new way of thinking about authenticating human presence on the web.
100% agree.

This time the "powers that be" are playing against the US consumer. I hope that this event sparks some empathy between the US and rest of the World. What many of the US consumers are suffering with the Olympics (broadcasting delay and accessibility), is what the RoW suffers when trying to consume US media (film and TV).

Monetising today's content with an old distribution model is a dead business, and will only help support the consumption of "pirated" content.

There are many types of DDoS. Some max out your CPU, some your network. Given that a DDoS (Distributed Denial of Service) involves potentially thousands of willing or unwilling systems, it's relatively easy to make a server unresponsive.

I have a 100 Mb/s internet connection. Scale that up to 10000, and you have saturated even the fastest of internet connections.

Mitigating a DDoS is not easy. Heck, its damn near impossible, considering the fact that DNS DDoS attacks are done via UDP, which allow you to spoof the source IP address. Even if you do block the IP address of al the attackers, your upstream provider is still impacted by the packets trying to come into your server. Most upstream ISPs will blackhole your server IP to diminish the impact on their network.

I believe a cookie is a datum given by the server to the client so that the client may present it to the server when making requests later. This is entirely voluntary on the part of the client; the client is free to pretend it has never received any cookies, or to present a made-up cookie (though the server would likely recognize that as suspicious). Browsers are likely to mindlessly accept cookies from servers and to obey servers' instructions as to when to present the cookies back to the server; but obviously a bot is likely to be more sophisticated, and to not present any cookies other than ones that say "You have successfully authenticated yourself as user xxx".

ReCaptcha is free from Google. I would hazard to guess that it is free because the value of the data Google collects is greater than the cost of providing the service. What I notice is that user convenience and blocking bots don't directly enter into the value Google derives, they are only marketing points - i.e. what matters to Google is that the perception of ReCaptcha is suffiently positive that a stream of relevant data is provided.

It would seem to me that having data on an individual's ability to solve Captcha's might provide some correlation with educational, economic, and social characteristics which is potentially useful to advertisers.

I just can't really buy into the idea that Google is offering ReCaptcha as charity.
HTML5 should introduce something better than captchas, I wonder why it was not made part of the forms elements ..
It's sad that the London 2012 Olympics doesn't have a public API. If there was we would have seen a lot of awesome implementations from developers.
Just to add some points/clarity.

The industry being discussed is called FMCG, abr. of Fast Moving Consumer Goods.

FMCG industry is characterised by few major players, controlling most of the market leading brands.

Such control is achieved through (1) marketing, (2) distribution and (3) mergers and acquisitions (M&A).

The simplified explanation:-

1. Marketing.

To win the consumer market, the brands shall win over the general population by delivering brand message/advertising through channels that reach the most of the population. Last 10-15 years such channel was TV. TV advertising is very expensive.

The cost of launching new brand varies (country, market, etc) from $ 3-5M (small brand, one country) to several hundred $M (global launch, major market, etc).

To maintain the market share, brand ad spending shall more or less match such spending of the competing brands.

The annual marketing budget of FMCG company can reach 15%-20% of revenue, with appr. half going to TV.

So a company with annual sales of $10B would spent annually on marketing $1-1.5B. As a specific example, 10 years ago Coca-Cola was spending on marketing in excess of $1B.

Therefore, new entrants/smaller companies can not match such spending either for new launches or for sustaining the market share for their own brands.

2. Distribution.

Most of the big players, like P&G, Coke, Pepsi, etc do direct sales/delivery and own fleet of vehicles to deliver goods to both chains and individual stores. Such fleet may cost tens of millions of $. Without such fleet in place [and existing relationships/clout with retail], new entrants can not ensure proper distribution/availability of their products. So even if they find money to spend on marketing campaign, when the customers will go to stores, they will not find the advertised brands and will buy what's available.

3. M & A.

Those companies/brands that find a way to break in through

- clever strategy

- by playing in new and emerging market segments (Gatorade, etc)

- catching a trend (BodyShop, etc)

are acquired by Big Co after they become clear winner and catch with consumers, but before they reach critical mass.

I wish people would stop harping on about the UK TV licence fee.

TV in the US is not free - you pay for it every time you buy something made by a company that spends money advertising on TV.

It's practically impossible to opt out of paying for TV in the US. At least in the UK you can opt out if you genuinely don't want to watch anything.
I did not delve into private labels, pricing matters, retail strategy and pricing, P/E and other bits, since the above is key and post was getting lengthy.

If you have an european ip, go to
http://www.eurovisionsports.tv/london2012/index.html

It's the official site of all european broadcasters.

You have access to all the live streams (without commentary) from all the arenas and all the live streams from all european stations.

Just enter bbc, zdf, ard, etc... in the search box to get the corresponding live stream with their commentary.

It also works if you are blocked on the broadcasters website (e.g. i can't watch the zdf live stream, but can watch it here).

They have live streams for each olympics and for some special events.
As mentioned above, I was happy to find TotalSpaces (http://totalspaces.binaryage.com/) which allows you to disable it completely!

There are thousands of flash crashes a year in single stocks on the market, usually explained by algorithmic trading or mistakes but could also just be blind panic as the rational market adjusts to news, rumour and FUD. Usually these stocks are suspended and any problem trades reset.

Whether these are exacerbated by hft is hard to tell, but I can't see how it would help damp volatility. Probably they have more to do with momentum investors and algorithmic trading, though they can easily happen with only human trade too, just at a slower pace. Would be interesting to see stats on volatility going back decades, but it's probably quite a complex subject for a layperson.

Here are some examples:

[IANAL] My understanding of copyright is that for events such as the Olympics, copyrights are often licensed licensed a country by country basis and that the retransmission of material across national boundaries is a violation. Doing so violates the author's right to control their work because it bipasses the arrangements the author has made to control their work. Incidently, this rests on the same legal principles upon which much of FOS software community operates (the license terms are merely different).

However, I would recommend speaking with an attorney familiar with such matters.

Damn, people were kind of hard on you. I think it's very clever. Even though sometimes our inventions don't work as perfectly as we expected them to. Your captcha system is new and fresh and many bots are not prepared for it. I'm sure you'll improve over time, the bots will improve over time, you'll counter, so on and so forth.

I'd rather have my signup system use areyouhuman than re-captcha. What makes me uneasy about using it on a massive site is the whole html5 + flash dependency. And the audio captcha alternative you have is terrible. I have better than average hearing and wasn't able to understand anything on my audio sample. That and the re-captcha system helps digitize books while areyouhuman is just playing games. Even though I hate captcha it makes me feel like I'm helping digitize a book when I use recaptcha, so I feel better about it. On the other hand your games are interesting and dare I say it, a little bit addictive, especially with all those congratulatory stars at the end.
I don't think it would, really...
They must have negotiated some international broadcasting rights; BBC 1 and 2 are on many Dutch cable systems, and show the Olympics live. And that is not because it was easier for them to get rights for this Olympics; they did this with all previous Olympics, too. BBC iPlayer is not available in the Netherlands, though.
Interesting sentiments, I don't know the IOC but neither of you are providing any reasoning behind your claims.

Out of curiosity, why the hate?

Only by going through the web browser, which apple can't now shut down without alienating too many users. If they thought they could get away with it, they would.

They have actively worked to disable any other store - for example, the kindle app cannot allow purchases or even link to the kindle store online, you have to manually search out links online instead, then download. It's absurd, not in the users' interests, and an abuse of Apple's power over the platform, but that's what Apple require.
Yes of course (and it is not a charity project, either). The fact that you are linking ReCaptcha to a valuable data stream for Google seems to support the my general claim that Google is deriving value from the data stream.

And perhaps the collection of that data almost exclusively at times when a single identity can be correlated with a single datum ( i.e. account creation and management) is merely coincidence.

But surely you are not suggesting that Google is ignorant of this fortuitous situation and its implications for their online advertising business.
