YUI Compressors

Easy things first! As you know, I have a back log of posts that I have to dump out of my brain into this blog. I will start with the easiest.

YUI Compressor. This is a freeware from YUI. I was looking at the MultiThreading in JS post in infoq.com and found that this Concurrent.Thread.js is around 500KB. Which is quite big for a js file. And imagine the poor vistor of my site from Bugaria on a dialup with 56 Kbps line, This page is as good as a download! So, What can be done? 1. Compress the JS, 2. Then Gzip the data transfer. Well The second option might not be in *your* hands as a developer, the first is always your decision.

Using YUI is absolutely easy. Download the jar file and run
java -jar yuicompressor.jar myjsfile.js

And you got a compressed and obfuscated file (would you not want this! The users can no longer steal your js code!). You can also do this to your CSS files. There are other compressors like dojo, JsMin but this one beats them all.

One page Stock

Alright.. That was a long absence. The whole last week I dint blog. I dint go away. I was "occupied". I was learning stock trading. Its very fascinating. I have a good weeeked blog for you all. Here is my experience. I can literally hyper-link every word from the following paragraphs, but I am writing it as simple as I can so you can look up the italicised words in wikipedia . I got a paper trading account from a brokerage firm . You need one brokerage account first. Then it can be an Equity account where all your money is yours or a Margin account , where some of the money is lent by the brokerage firm. Then I get Buying power , which is the dollor value of how much stocks you can buy. I can make profit by simple rules. Buy when Price is low. Sell when price is high. There is another more intersting way of earning money. Selling short . Thats when price is not high, per say, but when are confident that the price WILL go down. then buy back when its lowest. This is what

Decorator for Memcache Get/Set in python

I have suggested some time back that you could modularize and stitch together fragments of js and css to spit out in one HTTP connection. That makes the page load faster. I also indicated that there ways to tune them by adding cache-control headers. On the server-side however, you could have a memcache layer on the stitching operation. This saves a lot of Resources (CPU) on your server. I will demonstrate this using a python script I use currently on my site to generate the combined js and css fragments. So My stitching method is like this @memize(region="jscss") def joinAndPut(files, ext): res = files.split("/") o = StringIO.StringIO() for f in res: writeFileTo(o, ext + "/" + f + "." + ext) #writes file out ret = o.getvalue() o.close() return ret; The method joinAndPut is * decorated * by memize. What this means is, all calls to joinAndPut are now wrapped (at runtime) with the logic in memize. All you wa
