I have a loop that iterates 28000 times, when i deploy it to server, it takes around 1.5 minutes to execute. When i am running it locally on my machine, it only takes 2 seconds. I tried everything but it is still taking time.

My server has more resources than my local machine so memory and space is almost thrice than my local machine has

Hey Guys,
I appreciate this is not java related, but the recent disappearance of Malaysian flight MH370, and similar air disasters, and disappearances, which result in hefty costs, lengthy searches, and investigations, have left me pondering about something.
Is there not a possibility of streaming live black box data (voice + flight data) on the cloud, in such a way that whenever such tragic events occur, there is readily available data to analyse and investigate?
Don't we have enough technologies and scientific research to enable this?
How much data per flight would that mean ?
What are the limitations?
Are there any security concerns?
Does the frequency at which these disasters occur outweigh the need of such technology?
How costly would that be - say per flight? Not long ago, I watched a video online where James Gosling was explaining how streaming data into the cloud from a robot in the sea, is something like a $1 per kilobyte in their liquid robotic project...
It would be interesting to know your thoughts on the subject...

Thank you,

thanks for prompt reply, could you please check below query

I have an application where there are 1000 columns in database, each column value is calculated based upon a formulae. This formulae can be modified by a user. I need a way to map these calculations to a particular column in database in such a way that it can be edited by a user.

For example :: My table has 3 columns, COL_A, COL_B & COL_C
I have a calculation which says :: VALUE=COL_A+COL_B

In future, if a user wants to change this calculation say for example :: VALUE=COL_A+COL_B+COL_C then this change should get reflected.

Which is the best way to do this ?

I have an application which has 10 million rows and 1000 columns in Oracle. Each value has a different set of calculations that are stored in User Defined PLSQL functions.

Data is displayed in form of data grid. When a user updates any value, the calculation is performed using plsql function and value is stored in database. Is there an easy way through which calculation is performed on the fly and i get maximum performance ?

There are a few quotes I think of when thinking about computer design. These are not specifically about computers, but I think they are appropriate.

Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.
-- Antoine de Saint-Exupery, French writer (1900 - 1944)

"Simple can be harder than complex: You have to work hard to get your thinking clean to make it simple. But it’s worth it in the end because once you get there, you can move mountains.”
Steve Jobs -[BusinessWeek, May 25, 1998,]

Often contentious topics can labour under the assumption that it makes any difference in the first place.
DEVENTER (n) A decision that's very hard to make because so little depends on it, such as which way to walk around a park

-- The Deeper Meaning of Liff by Douglas Adams and John Lloyd.
Everyone can learn something from your mistakes
Mistakes - It could be that the purpose of your life is only to serve as a warning to others.
-- Ashleigh Brilliant on on

Remember to keep what you are doing relevant
Computers make it easier to do a lot of things, but most of the things they make it easier to do don't need to be done. ~Andy Rooney

Information technology and business are becoming inextricably interwoven. I don't think anybody can talk meaningfully about one without the talking about the other. ~Bill Gates

Making things simple and clear should be much of the design effort. Not just something which works.
A computer will do what you tell it to do, but that may be much different from what you had in mind. ~Joseph Weizenbaum

Doing very little, often enough, can quickly add up.
The inside of a computer is as dumb as hell but it goes like mad! ~Richard Feynman
