The beauty of Fibonacci deserves a jacket

Sybase guys know this number. Hmm, they used to include that spiral in their logo.
But yikes, I am NOT going to pay $300+.
The most fun numbers that I know of are π, the golden ratio φ and e... There must be other very fun things out there, but may be too hard for me to comprehend.

Tour de Flex
Flash has revolutionized the web from plain old HTML... but it wasn't so easy to learn. 1. the tool isn't free, 2. it seems so graphic oriented, it isn't write-compile-run like the typical programmer is used to.
Flex is a very cool Rich-Internet-Application tool. It is not so new anymore, now in version 3 (soon version 4). It also creates SWF files. What I like about Adobe is that it encourage you to learn its tools, with tutorials nicely available and Flex doesn't look so hard to learn. Its compiler is free, yea, the Flex Builder will cost you some money but you don't have to have it.
See the Tour de Flex to see its features.
It is much like HTML combined with javascript, so the web programmer should find it fairly easy to master. It's got all sorts of animation things that are hard to do built in, such as fading, glowing, zooming, etc
It is NOT just a sandbox like java applets, it can communicate to other urls or webservices, making rich application possible...

What's wrong with this chess set?
I saw the Barnes and Nobles' classic wooden chess set. (Here is the link).
Hmm, seems like a good looking set that is reasonably priced.
But what's wrong with the package?
This photographer NEVER played chess. The lower right hand corner should be WHITE!
I have seen more than 1 set that has the wrong set up.
Though I think an elegant chess set is a nice-to-have item, but no one plays with me && I can't afford a very elegant set.

Studying Spring
Just got the book Spring in Action. Short term goal is to read it and understand it. Spring/Hibernate is now a must have skill for Java developers. No Spring => no work => starvation.
Yes, there are plenty of resources on the web, but nothing beats in depth discussion on paper.
Spring has been around for a while and introduces 2 buzz terms: Aspect Oriented Programming and Inversion of Control. But the real accomplishment is acceptance. People want it.
Opinion: In the ideal world, there should be NO XML configs. Everything can be configured using a UI tool. Perhaps someone (ME perhaps) should come up with it and further simplify programming.

The Mαth βook
This Mαth βook is an awesome work. It is one-page-a-topic, listing milestones of discoveries. It is colorful and well laid out. Of course, given one page a topic, it can't go a lot in depth. This is a perfect gift item for math enthusiasts. I have only heard of perhaps half of what's in there when I skimmed through it.
Math does not have to be boring. Colorful pages helps. When is the last time you saw a colorful math book?
Real math often demand only 1 color: the chalk on the board (and often ugly looking notations and equations)
