"We don't view that kind of activity as an appropriate activity for one partner to do to another."

Above are the words said by a eBay spokesman against Google's act of having the Checkout Freedom Party at the same time of eBay's meeting with its users. So, eBay pulled its ads out of Google's Adwords. Google cancelled its party. Its a slap for Google from the online auctioneer giant eBay. Win for eBay and lose for Google.

Abt Tomcat and Comparision between that and my project

Note: This may not be useful for those who know abt Tomcat.
Had a small discussion in my room with my friends. They are working on jsp's, servlets and tomcat. They were asking qn's like - on what requests, tomcat won't support redirection? how to set that header? and how to do the redirections etc.... I was not knowing abt tomcat previously. By listening at those qns, I got some idea on that. Here is a small update for those who doesn't know what is tomcat.
Its nothing but a server which can be used to implement webservers. It will receives request coming from the browser and allows the following things to be done by programmer on that request:
- to analyze the received request's headers (HttpServerRequest class will help us)
- to make the response for browser based on that (HttpServerResponse class will help us)

Memory Related issues detection tool

Since last 3 to 4 days, I hadn't done even a single defect fix. Time was getting consumed in reviews, meetings and investigations. In the last 3 days, I was getting tired too much. Finally, found the reason for that - I was not hearing to Music last 3 days. Ok, this blog is to explain some tool that I learnt today in detecting memory issues like leaks, corruptions, heap usage etc....
It is MemoryScape. Its a good tool. This can be attached to the running process, or the core that got generated or the new program that to be started.
First, faced problems in attaching this to my binary file - as my binary file not generated using the libraries provided by this tool. Finally was able to do by using LD_PRELOAD environment variable.
But, leaks reporting is not happening. That tool provides some so's. At the time of linking, it makes any fork or malloc or free calls to its functions and then it tracks them. And, then, internally, they call the original functions.
Attached para is copied from its document:
Behind the Scenes

MemoryScape intercepts calls made by your program to heap library functions that allocate and deallocate memory by using the malloc() and free() functions and related functions such as calloc() and realloc(). The technique it uses is called interposition. Our interposition technology uses an agent routine to intercept calls to functions in this library.

In the similar way, fork also gets intercepted. Just compiled my code with them and yet to test them. In the mean while compilation is going, thought of putting this here....

Finding large files in your linux box

My HD was reaching 100% usage now and then. So, I want to find large files in my box and delete them. I don't know scripting. Google made me to reach here.
find / -type f -size +20000k -exec ls -lh {} \; | awk '{ print $9 ": " $5 }'
In some linux boxes, we may need to change the parameter $9 for print as $8 or something else
Got the above one from this place
Just thought of putting it here

"Street View" in "Google Maps"

New "Street View" in Google Maps is an idea which have both the faces. It frowns people as it peeps into their privacy. And on the other side, we can't stop ourselves admiring its technology and idea.
Google made contract with Immersive for licencing the idea of taking 360-degree street level images.
Vans are there roaming in the streets that captures the photos in different angles (I think somewhere I read it as 11 angles). This link explains about the SICK device used in the vans. The real time challenge is the image processing system where it collects all these images and give a proper images to the viewer. Somewhere, I read that they are using Nikon DLSR cameras.

Split Pannel - Xn for Firefox

I don't know, but, somehow I like these extensions very much (may be becz they are very smart). I got introduced to these by Ramki (my buddy at Novell). Today, while Googling, thought of some extension for browser that splits it like 'vi's split or vsplit' command does, so that, instead of opening every link in new tab and close them again one by one, we can have it in the same screen but divided. Looks like this "Split Pannel" extension will do that work. I installed it but yet to look how it works. For this, I need to close my browser but I rarely do this (ofcourse, I have the "session manager" extension to firefox which will open all my closed tabs at a time).
I guess this "Split Pannel" should work and solve my issue (its not a big issue, but, still an issue) :)
Too much, in a single day, I wrote 2 blogs. Ofcourse, this what usually happens, afterwards, I won't blog for many days. Tomorrow, I will blog on Google Maps.

Microsoft Surface

Looking at the Microsoft Surface, felt very astonished. I was thinking what and all different styles of algorithms - Surface computing, Geometrical algorithms, Ubiquitous computing etc - they should have implemented for this. Thinking of the work that I'm doing now - felt very bad and embarassed. Ofcourse, I'm in networking field - but I don't think I'm implementing latest things in this space also. ('m too bad that I don't have idea wats happening in this field). Still hanging over the (g)old HTTP protocol (ofcourse, https and other network protocols also). But, this is my level and I will improve myself.
Watever it is, this product from Microsoft is good (usually, this is not the case with Microsoft - my personal view). Hats off to Microsoft for this. Let us see what happens in the future - there is long road ahead....
