How to Resize All Window Columns with a Single Keystroke

When you’re dealing with an application that displays data in a set of columns, it’s often frustrating to have to resize each column separately—but today we’ve got a great trick for you that resizes all the columns with a single keystroke.

The secret keystroke to use is Ctrl and the Numpad’s + key, and it only works if you have a separate number pad on your PC.

Working with 'vi' editor

People who use Linux/Unix as their OS should have used the vi editor. This editor is more powerful editor I've seen ever. I'm here with listing some basic & important 'vi' commands which needed to do file manipulation/editing.

Save & Exit:

:x --> quit vi, writing out modified file to file named in original invocation
:x --> quit vi, writing out modified file to file named in original invocation
:wq --> quit vi, writing out modified file to file named in original invocation
:q --> quit (or exit) vi
:q! --> quit vi even though latest changes have not been saved for this vi call

Screen manipulation:

^f -->move forward one screen
^b -->move backward one screen
^d -->move down (forward) one half screen
^u -->move up (back) one half screen

Working with Multiple files:

To open multiple files:

$vi main.pl maintenance.pl

To hop between them:

:n --> Next file
:prev --> Previous file
:args --> To see which are the files open.

Eclipse IDE tips

Often I hate with Eclipse editor is, switching between editor. I mean if you have multiple java files opened with eclipse one way to switch between 'next files' using default shortcut 'CTRL + F6'. To do that ideally you have to use your both hand to handle it. I mean F6 key is all the way up on the top where as CTRL key is all the way down to the keyboard.



You can change this default behaviour and make it 'CTRL + Tab' like other windows application. To do that make a 'Binding' for the command Next Editor under Window > Preferences > General > Keys.



After changing this, you can pretty much switch between files easily with your left hand.



I'd ask every programmer to think all these kind of small small things to make their life better.

Screen capture - Java

This might be very helpful for GUI developer in java. At times its hard to figureout the some error happens in the user end. I mean, End user usually just complain that while clicking so and so button or tab or something it failed. In those cases if you have users screen, you can guess something. To do that, you can make the following code as an API and store screen shot in your log location and you can verify them later.
