If you are connected and logged in sql plus and want to know the version of Oracle you connected to via sqlplus command, following are the quickest methods

1. Type ‘define’ in SQL prompt(ex :SQL> define)
2. use query – select * from v$version;
3. use the view called - product_component_version.
4. check the registry (though this is not through sql plus )

Hope everyone worked on DOS (NOT Denial Of Server, its Disk Operating System :)) remember the command ’Cd\’. That’s something which everyone used so frequently. Now in Windows PowerShell you have to use “Cd \” (notice the space between d and slash), come on Powershell guys does this change really required ?? I am sure its a bad decision making.

I am doing Test Driven Development in my current project. I have used TDD before when I was doing some component development, but this project is entirely different, this is a normal product development using Agile methodology. And as in any other product development the requirement keeps on changing. So this is really interesting.

During one of the discussions I had a conflict in opinion between different test doubles. There is no clear distinction between them isn't it ? I found a nice article in msdn magazine. The image below(from the article) gives better picture :)

As mentioned in the article there is not clear boundary between most of them.

TDD Rocks!

Enthalpy, joules per kilogram(J/Kg), psi, Kelvin, viscosity ... remember this ?

Yes I am back to these now, I think the last time I used these words was when I was in college. You will be wondering what happened to this fellow uh...

I am currently working for a Oilfield services corporation. I am learning about well(the one which gives oil not water), drilling, seabed etc.. these are very exciting things. I started remembering about my college days, mathematics was fun isn't it..even though I am a physics graduate I loved mathematics. Maths in Physics was fun(in a way), you start from a small equation and then you expand it expand it and it take few pages of your notebook and finally it becomes a very small equation. I remember once my professor after one hour of problem solving finally came to e=mc². Its fun isn't it..

yeah instead of taking it as fun, I would have studied then now I would have become some scientists. Like the guys sitting in my company :(...
