Data Majestic. Scalability thirsty Apps.

I have been interested on scalability of Humongous apps recently. Google declared the first ever free real time stock quotes provision today. So Tomorrow morning, If you are on Google Finance, You are not watching the 15-20 minute delayed results.

For an average Joe, this might be just another thing google can do. But for Technology enthusiasts, This is a much interesting step. Just give you an idea, a few days back Facebook opened up its chat feature to its ~70 million strong member base. Google does a similar feat with its Chat integration for its, I don't even know how many, million users. IMs are the least of issues. Presence Notification packets, Security, Keeping so many connections open, memory to handle all these are of highest consideration. It would be interesting how Google will explain feed polling from NASDAQ and delivery and still keep it realtime for Gigillian hits google.com/finance gets every day. What is even harder to imagine is how an open webapp(even available for unregistered visitors), will handle all these challenges and more.

This is just the tip of the iceberg, there are so many technical aspects. If this post locked you in for scalability, Get more here

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

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
