More cool stuff was done in this video than I've probably done in the last year.

Bing-it-on results. 3-0 Google vs. Bing with 2 ties. Does anyone actually get better results with Bing?

Only people using "Bing-it-On" to search for stuff they don't really care about finding will find Bing more useful. For example, the people in the study that showed a 2:1 preference for Bing were asked to make 10 queries in series, and had no goal defined [http://www.bing.com/community/site_blogs/b/thedetails/archive/2012/08/06/bingchallenge.aspx?form=MFESOC&publ=BGITON&crea=TEXT_MFESOC_Challenge_Desktop-Landing_prblog-desktop-upper_1x1]

They weren't looking for information; they were participating in a study, and probably just trying to get paid.

I tried the last 10 searches from my browser history in Bing It On. Bing kept returning introductory information (e.g. "what is a landing page?"), or random forum posts, while Google was giving me specific answers (e.g. "how to write a landing page"). This tells me that for my searching style, Google serves me better. The score was 9-0-1 in favor of Google (the one draw was only because I have yet to figure out why my IFTTT Craigslist recipes keep turning off.)

If I want an intro into a subject, I'll use Wikipedia.

I also noticed that Bing doesn't seem to index PDF files. Or if it does, it didn't think that a PDF titled "Magic: The Gathering Comprehensive Rules" was a suitable result for "magic the gathering enchantment rules type change".

Pretty amazing graphical representation of bot trading on the stock exchanges... little do people know, the machines are already in control!  ;-)
 
The Bots Go Berserk

Stock market trading is mostly done by computers.  Watch them go wild!  The date is at lower left.  In 2000 it took several seconds for computers to make a trade.  By 2010 it was milliseconds... or even microseconds.   You can see stock market activity become vastly more intense.   I can barely see the Flash Crash on May 6 of that year - also known as the The Crash of 2:45, when the Dow Jones plummeted 9% in 5 minutes, then bounced back.  But on August 5, 2011, when the credit rating of the US got downgraded, activity explodes

This image was created by Nanex, a company that provides market data to traders:

The x axis shows the time of day, from 9:30 to 16:00.  The y axis... well, it's the number of some sort of activity per unit time, they don't say what.   Do you know?  

But they say something interesting:

It's not high frequency trading that they're worried about - that's actually gone down slightly!  What's shot up is high frequency quoting or quote spam.  Can someone explain that?  Here's a paper on it:

http://www.cass.city.ac.uk/__data/assets/pdf_file/0018/128232/Hasbrouck.pdf

but it doesn't answer the simple question of what's quote spam and why people do it.  To make money, obviously, but...

Thanks to +Alexander Kruel for pointing this out!

I'm trying to watch another keynote speech, and dear god it's painfully slow.  When are online video players going to have a 2x speed option by default?
