Opera Unite – Check out this video

Dipesh Khakhkhar — Tue, 16 Jun 2009 09:14:34 +0000

Opera’s new browser has a unique capability of turning your browser to server. Using opera unite one can share photos, files, videos etc. One can create his own cloud and share with his friends/family. This was required so badly when there are so many “me too” sites for sharing photos, videos and so on. It also allows to host your website. Opera unite will allow user to share your cloud with your known contacts. This will eliminate the need of 3rd party web server and uploading photos to 5 different web sites.

I have installed this build and have used it’s file sharing service to share a file (opera unite installation file). Check it out here

Go Opera!!

Story of WordPerfect – Change is the rule of life

Dipesh Khakhkhar — Fri, 24 Apr 2009 22:19:44 +0000

Seth Godin wrote a post about – Pick Anything- Calculus of Change and few days back I read a book (story) Almost Perfect (you can read the book online for free) about WordPerfect authored by one of the executive of the maker of software. The book describes the rise and fall of WordPerfect.

As mentioned by Seth Godin change in Operating System brought Microsoft Word into limelight and once ubiquitous WordPerfect is almost vanished now. Change is the rule of life where everyone participates and molds themselves. We can see change around us all the time – the way people are embracing Twitter, Facebook, Friendfeed, Blogs is one of the example of how these tools are changing the way people disseminate news and information.

That’s why we saw influx of web 2.0 start ups in 2006-2008 where every other entrepreneur was selling/marketting their ideas (no matter how crappy was it). For example if we consider 100 web 2.0 application then 15 survives and 5 of them excel and become maas’s product and that brings the change which we adopt by using these products.

There is inherent Power in Change and one has to capitalize the moment to make use of the Change.

Tech Mahindra wins a bid to buy Satyam Computers for 577.8 Million USD

Dipesh Khakhkhar — Mon, 13 Apr 2009 07:11:04 +0000

Tech Mahindra will acquire Satyam Computers at approximately $1.5/share for approximate total of $577.8 M (2889 Crores INR at 58 Rs/share ) Satyam Computer will operate as a separate entity with separate liabilities. There were other bidders too – L & T, Cognizant etc.

Tech Mahindra will buy31% stake in Satyam by paying $351.4 M approximately (1757 Crores INR). The transition procedure will be long and it will happen gradually. Tech Mahindra and Satyam Computers together will be a good competition to Indian/Major World IT Consulting Companies. They will be in same league as Infosys, Tata Consultancy Services, Accenture, IBM etc.

Tech Mahindra’s stock soared during trading at BSE.

This move is a good one for Satyam as a company but as usual with merger and acquisition there will be shredding in some division and removal of redundant positions at executive levels.

How to debug tomcat project in Eclipse 3.4.2

Dipesh Khakhkhar — Fri, 20 Mar 2009 07:01:08 +0000

Eclipse is one of the best IDE for software development in java, php, c++ etc.

I recently upgraded my eclipse from 3.3.* and 3.2.* to 3.4.2 and I took this step assuming all my plugins in existing eclipse installation will work as it is. But I have realized that there is huge compatability problem in eclipse upgrades.

I use tomcat for my java web application and to debug it in eclipse I was using tomcat plugin for eclipse. I followed the installation instructions (usually you have to download the plugin, unzip it and copy the uzipped folder to plugins directory in your eclipse_installation_directory) but I was getting this error

java.lang.NoClassDefFoundError: org/apache/tomcat/util/log/SystemLogHandler at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Class.java:2357) at java.lang.Class.getConstructor0(Class.java:2671) at java.lang.Class.newInstance0(Class.java:321) at java.lang.Class.newInstance(Class.java:303) at org.apache.catalina.startup.Bootstrap.init(Bootstrap.java:205) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:390)

I tried trouble shooting it using the instructions mentioned here but still no success.

I tried copying the unzipped folder to dropin directory in Eclipse_Installation_Directory still I was getting the same error as above.

Then finally, I tried using standard WTP tool in eclipse 3.4.* and after tweaking some settings I was able to debug my tomcat java project in eclipse. Following are the steps which I did to debug tomcat java project in eclipse 3.4.2 (I guess, it will work in 3.4.*)

1. Install eclipse 3.4.2
2. Start eclipse and go to window –> Show View –> Others –> Server
3. In this view create a right click and create a new server.
4. Please select tomcat installation directory and version information.
5. Then double click on Tomcat VX.X Server at localhost (Name of this server), it opens up configuration settings page
6. In the Server Locations Section select “Use Tomcat Installation (takes control of Tomcat Installation) and enter deploy path (using file browser, point to your tomcat project directory i.e. context path)
7. In the publishing section select Never Publish automatically and uncheck update context path checkbox.
8. Set some breakpoint in your tomcat project’s source code and start tomcat in debugging mode

Hope this helps.
