Lisperati

I think this is cool. It's definitely bizarre.
There are funny tutorials for Haskell and Lisp.

Information Visualization

I went to a cool talk (video should eventually be available) at UW by Jeffery Heer, developer of the prefuse visualization toolkit, at Berkeley's Visualization Lab.

His Flare toolkit, a flash-based follow-on to prefuse, also seems to validate my desire to ditch Java for this sort of thing and move to Adobe's platform (flash/flex/AIR).

Mentioned during the talk were: GapMinder, ManyEyes

A related class at Berkeley on infoviz. I suppose, if I get interested in this stuff, I ought to read those Tufte books.

What Google should do

Since nobody asked me, let me tell you. Google needs another revenue stream. Advertising is a cyclical business, headed straight down just at the moment. And commoditized online advertising probably isn't a big enough business to sustain an operation the size of Google in the manner to which they've become accustomed. 

But when you're as big as Google, what businesses are worth getting into?

Micropayments

How much does VISA take in per year? I dunno, but I'm pretty sure if you want a money fountain to finance an altruistic geek nirvana, that's the kind of revenue stream you want.

Where support by advertising is a poor fit you need a way to keep the lights on. Charity and community spirit work for some efforts, but some things require the luster of cold hard (micro) cash. For the information economy to become a reality, this is a requirement. Many others have tried and failed, but if anyone can make micropayments work, it would be Google.

Medical records

There's a mint to be made data mining the nation's (or world's) medical records. Just collect the data and lease it back to the pharmas, biotechs, and academic researchers. The big roadblocks, which Google might have enough good will to overcome, are (justifiable) privacy concerns and the pathological motives of vested interests in the field.

Ok, I guess the GOOG is way ahead of me on both of these...

Lecture videos online

You can become a scholar these days just by sitting in front of your computer watching video lectures.

• Structure and Interpretation of Computer Programs: Videos of Abelson and Sussman's classic lectures
• Donald Knuth lectures online
• ResearchChannel
• Ars Digita University
• UW's Professional Master's Program in Computer Science lecture videos.

A blog called FreeScienceOnline has a better course catalog than most universities.

• UC Berkeley's youtube collection
• MIT's public events videos and Open Courseware
• Videolectures.net lots of computer science, machine learning, and bioinformatics
• SE-Radio Software Engineering Radio - the podcast for professional developers
• parleys.com geek oriented video lectures

Updates

• IEEE new media
• Hidden Video Courses in Math, Science, and Engineering from the data wrangling blog
• Must-see TED talks
• A Brief History of Mathematics
• MIT's Calculus Revisited

A couple discussions about computer science lecture videos on stack exchange.

What a drag

Java's drag and drop functionality is painful. What I want is a list that the user can reorder by dragging. Here a couple of nice efforts with the caveat that they work only for single selections.

• Swing UI Stuff
• rabbit-hole's ListAnimator

Sun's tutorial is here. There's a chapter in O'Reilly's Swing Hacks about it, but their code seems buggy to me.

Classcycle

Classcycle is a tool for analyzing dependencies among Java classes and packages. It can really help when trying to make sure you haven't introduced any unintentional dependencies. It's similar to JDepends, but a little more up-to-date. Its output in a nicely formatted web page (actually an xml + xsl -> html deal). 

Programming Languages are where it's at

There's a lot going on in the world of programming languages these days - from functional/OO crossbreeding to new language constructs for concurrency. Here's a few random interesting tidbits:

• Paul Graham's essays
• Lambda the Ultimate the slashdot of programming languages
• defmacro: a few good articles
• Classes versus prototypes in object-oriented languages

Oh yeah, and concurrency is where it's at too:

• The Erlang Book
• The Transactional Memory / Garbage Collection Analogy.
• Larry Snyder's Principles of Parallel Programming
• Herb Sutter's The Free Lunch is Over
