RoR and Scalability

I always had a doubt on the scalability of Ruby on Rails (RoR). I happened to meet a few RoR evangelists from ThoughtWorks at JAX India 2007 and I asked them about it. However, the answers I got were not convincing. Now here is an account of a guy who has encountered actual scaling issues on a production site and is quite honest about it as well!

Use of Recursion!

This piece from Stevey's blog was hilarious! - The engineer has formulated a proof that invalidates one of the most fundamental results in Computer Science, specifically that "recursion" and "iteration" are formally equivalent.

The anonymous author of the paper has found that there is in fact one thing you can do using recursion that you can't do using iteration, namely: "You can use it to weed out stupid fugging interview candidates."

Yahoo using Google Code..!

There is a really cool syntax highlighter in the YUI documentation. I was wondering how they did it and clicked on the "?" link, that opened an about page that said "dp.SyntaxHighlighter" Version 1.3.0, with a further link to http://www.dreamprojections.com/syntaxhighlighter/, which redirected to know where? http://code.google.com/p/syntaxhighlighter/. I thought it was very interesting. Kudos to Yahoo! for not having the NIH syndrome!

And also, great job Alex!

YSlow Benchmarking

I was playing with YSlow for Firebug, a neat little tool from Yahoo!. It is actually a plugin to Firebug which analyses the performance of your web pages. My projects barely managed to get a passing grade :(. It was fun to check the performance of various sites:

Site	Score	Grade
Google	99	A
Yahoo	93	A
YouTube	62	D
Netvibes	54	F
Myspace	58	F
Slashdot	51	F
CNN	35	F
Impiger	64	D
Infosys	51	F
W3C	79	C

Welcome to my Tech Blog

Hi there. I hope to post technical related stuff in this blog. I've named this blog in honor of the first PDA I owned in 2000, the amazing Palm Vx.
