Need a Library Book? Have it Scanned... free

I just found out about openlibrary.org, which has to be the coolest "online library" I've seen in a while.  Not only do they index millions of actual library books around the world, but they actually have the text of over 1 million of them available online, right now.


What's more, if they don't have the text available online, you can simply request to have the book you're interested in scanned and added to the online library!  It takes about 3 to 5 days according to their invitation.

Unfortunately, OpenLibrary is under attack by a backwards-thinking company called WorldCat that hopes to shut down the "little guys".  I'm sure WorldCat has something to offer the world, but if they hope to get onboard with the 21st century web, they'd better start thinking inclusively.

OpenID is set to take over the web this year

Say goodbye to multiple logins... at least, here's hoping.  It looks like the OpenID standard is about to break out this year: last year the number of sites supporting the standard more than doubled from 10k to 30k.

Air Quality in Provo has been Terrible

I used to think Provo was a healthy place to live (it is, for the most part) but I've recently had to update how safe it is to live here.  The air quality is absolutely terrible during an inversion, as evidenced by this US air pollution forecast.  Basically, we're the worst in the country right now.  Worse than Chicago, NY, even Los Angeles.  Yikes!

The Whitehouse has a Blog

The change begins.


Also, check out this interesting "tag cloud comparison" of Obama's speech today with other presidents' inaugural speeches.  Obama's seems more balanced somehow, which is kind of encouraging.  Take a look.

The Real Cause of the Financial Crisis

This former MIT Blackjack Team member's perspective is the best synopsis of the underpinnings of the crisis that I've read to date.  Read the article here.

jQuery 1.3 looks great!

jQuery is the javascript library that I've grown most fond of, especially because of the livequery plugin.  Now, with the recent release of jQuery 1.3, it looks like they've incorporated livequery into the library itself (using the ".live" and ".die" methods)!  Not only that, but the speed improvements look delicious! 


I'm also quite impressed with the speed improvements overall (according to their website).  jQuery has already performed wonderfully, IMHO, and so I'm amazed they could squeeze that much more out of it.

Congrats!

Anthropic Justice and Statistics

I'm diving into a full semester this year with some of my most anticipated computer science classes all falling in at the same time: I'm enrolled in Statistics, Computer Graphics, Parallel Processing, Algorithms, and Bioinformatics.


I had an "aha" moment today while thinking about a principle we learned in statistics called the Simple Random Sample.  The SRS is just what you would expect it to be: in order to find a "representative" sample of things within a larger set of those things, you need to randomly choose them, i.e. you can't bias the choices or accidentally prefer things by, say, using the "lazy method" and picking the 10 closest tires when you walk into a roomful of stacks of tires.  If you did, it wouldn't be a random sample.  The principle is based on this idea: in order for a random sample to be representative, every one of the things in the full set has to have an equal chance of being chosen for the "sample" set.

Isn't that interesting?  As human beings, we rely heavily on our "intuitive" statistical sense of things.  This is absolutely necessary because we have to try to make sense of a broad world from a small subset of its information.  In other words, we almost always deal with "sample" data on a day-to-day basis and we have to hope that it is representative.  For example, when walking down the street or in a park, we anticipate that people will generally not strike out at us or try to hurt us.  This intuition is based on our previous experiences indicating that most people just don't do that.  Whew, thank goodness!  :)

Ok, so now to get to the point... if our world is based largely on a need to find representative data, and if "representative" is, by definition, "having an equal chance of being chosen" from the full set of things, then might this be the source of anthropic justice?  We want the world to be "fair" and "just" so that our random sample is representative in order for our data to be highly predictive.  Justice leads to greater efficiency to individuals and groups because of the predictive improvements available in a just society (not to mention many other benefits).

I wonder if this hypothesis is testable...

3 Neat Websites

voted for github in the Crunchies contest and in doing so I found out about 3 great websites I hadn't used before:


  • lala.com, a music service that lets you listen to any of its 6M songs free on the first listen
  • animoto.com, a video-creation service that takes your photos and an MP3 file and generates a "music video" for free (30 seconds)
  • sliderocket.com, a "power point" killer that lets you create fabulous slides for free, online, with shared resources

Cool!

In an increasingly fast-paced world, will recessions be short-lived?

An article titled "The Economic News Isn't All Bleak" in the Wall Street Journal caught my attention today.  Information technology (as Ray Kurzweil has pointed out) has been improving exponentially for some time now.  Is the economy an information technology?  Perhaps it is.  If so, will we see a surprisingly fast recovery?  I think it's possible:

And yet, if things came to a halt more quickly than ever before, they could also restart more quickly than ever before. This is not to say they will, only that the possibility is more than marginal.

I'm hopeful that after correcting the wrongs that have taken place over that past 6 years or so, we might see something amazing.

In Spite of Differences, Obama is Connected to Us All

I haven't been entirely happy with Obama's various compromises and changes of heart.


But today, I realized just how connected to America he is, and I felt a little bit better.  As everyone notes first, he is black.  But he is white, too, and raised by a single mom.  His grandma died of cancer today.  His aunt is an illegal immigrant.  He's an active Christian.  His father is Muslim.  His mother was a humanist.  He's married, and has two young, beautiful girls.  He's smart and well-educated.

When we have so many divisive issues to talk about, who better to lead our country than someone with an understanding heart, someone who is connected in some way to almost every kind of person in America?  If I could vote, I'd give Barack a chance.

Good luck to all you voters out there today.  Let the counting begin!
