A Do-It-Yourself Quantum Eraser — [ PHYSICS ]: Scientific American

Beans Beans, who found this leaked corporate video, where a group of dorky Cool-Aid sloshed employees sing along, gospel style, to ‘O’ Happy Day’, puts it well:

“Ernst & Young teambuiding video - holy shit I nearly pissed myself”

Corporate accountants singing Soul; once more with feeling.

I’ve just watched it 5 times in a row and cannot stop, each time there’s one more priceless gem to notice.

Effing hilarious.

The real buuble.

Four words: Hedge Fund Private Equity.

I hear these too much. I don’t really understand hedge funds and private equity, but more frighteningly I get the impression that some of the people involved don’t either.

My one theory about the rise of Private Equity, is that its a natural reaction against the increase in communication due to things like the Internet, and the reduced arbitrage or spread that it creates as more people have access to information, more quickly.

One way of countering this and the recenty tightened financial regulation in the US is to deal in private companies and investment, where the information is more opaque.

The Limits of Computing

Lecture 5 notes

I found the above notes on Information Theory as applied to the limits of computing in my never ending quixotic and pretentious quest to look for a possible physical law of natural selection.

They are from a series of lectures at the University of Florida by Michael Frank, and are of staggering clarity. Its worth reading the whole lot.

Amusingly, the most interesting lecture seems to have been the one that students were most reluctant to hear.

“When I handed out the student information sheets, I asked you all to point out the particular topics you were most and least interested in. I tallied these ratings, adding 1 for each “most” rating, and subtracting 1 for each “least” rating, with no change if the item was unrated.

All of the topics received positive scores, ranging from 5 (for physics-based theoretical models of computation) up to 26 (for quantum computing), except for one topic: Thermodynamic constraints on computing received a score of negative 11″

I give it a +10.

The excellent One Good Move beats everyone to the punch with a clip of Dawkins on OReilly. Except there were no punches and the whole thing was rushed along as if it were a Gong Show skit.

Microsoft’s Live Search Is No Longer Live

ResearchBuzz has found this hilarious gem. Apparently Microsoft couldn’t create a way (huh, as RB suggests - what about captchas after repeated queries?) to stop data mining of their advanced live search - so they killed it.

Live Search’s Statement

Richard Dawkins will be interviewed by Fox’s Colbert style, fake, sensationalist newscaster, Bill O’Reilly, on Monday, April 23, at 8.00pm EST on FOX. The program will be rebroadcast at 11.00pm.

Should be fun.

If I were a VC this is a startup I would back.

If the money in a gold rush is made from selling picks and shovels, then Openfount are selling stainless steel Web 2.0 tools for the price of plastic ones.

They have built value-added products upon Amazon’s excellent S3 storage and EC2 pay as you go grid computing.

The most interesting is the distributed file system product. They give you a disk image to load onto S3. From that you can instantiate as many clustered machines as you want and have them share the same disk, with infinite capacity.

Simple and elegant. Stuff that used to cost six figures for a grand or so.

Trains Planes and Ruby on Rails - Is speed the most important thing for a successful startup?

Twenty years ago, I was reading a Graham Greene novel on a painfully slow train ride in Italy. In the book, he pointed out that your mood as a train traveller was directly proportional to speed.

Evan posts today about how the mood a Twitter HQ is directly proportional to the speed of the site.

I’ve noticed that many people running startups seem to have moods that are directly proportional to their Alexa rank.

I’d argue that fast response time is the unwritten golden rule of successful web apps. A site that is slow is like wading through mud. Before Youtube I could watch video on the web, but before Youtube, my expectation was that it would splutter and stall.

I suspect that focusing on speed is much healthier than traffic or, dare I say it, features. If you built a product with one great feature and make it fast, your traffic will come, people will understand what its about and the extra features can be added later.

Google had less accurate search than Altavista for a long time after they became hip (you couldn’t do exact phrase matching because ’stop’ words like ‘the, of, and or’ etc. weren’t indexed), but Google was always blindingly fast and they kept focused on one things even as CMGI made Altavista pour portal crap around their nice search page.

And anyway, Graham Greene said nothing about Alexa.
