Nebeans debugger msg : delete method not implemented

When I apply code changes using netbeans debugger, i get this message :

The virtual machine does not support this operation: delete method not implemented

and I am not able to apply my code changes.

The problem was :
I had another file where i had added a method and had not compiled. so not able to apply code changes. (debugger does not allow adding new methods. If you add or remove a method [or any other type of class member] you have to compile the code before using debugger).

Form submit in FireFox and IE

I am using FireFox 3 and IE 7 for my development.

For form submit, FF uses post as the default method. IE sends params as post only if specified in the <form> tag.

Installing Ubuntu

I got an Ubuntu DVD sent to me right from Ubuntu.

Since I had a half forgetten 'experience' of installing linux in the past, I assumed I should be 'very careful' while installing linux since I thought I should not make wrong choices.

So started 'planning' before installing. I studied from internet regarding
1. the partitions that I need to make
2. size and filesystems for partitions etc.

All my preparations went waste I should say.

Installing ubuntu was incredibly easier. All you have to do is just to make your system boot with the Ubuntu CD. Thats it. Ubuntu takes care of the installation. All you have to do is just watch the screen for a few mins and give your (very few) decisions then and there. It was easier than installing Ms Windows. Writing this post with Ubuntu - firefox.

Thank you Ubuntu Teams.

Will write more on my experience with Ubuntu - the 'linux for human beings'.

A wonderful post about technology

You find the beginning of the post here :

Technology: OK, but you will pay for me right?
Human: Sure! Will do.
Technology: Will you also update me from time to time?
Human: OK, I can do that.

IE handles memory better than firefox?

As i was working in my laptop, i felt the system went slower. When I examined the task manager (windows), i found that the highest amount of memory was held by firefox (312 MB). I closed firefox and re-opened it. I wanted to examine how firefox gulps up memory - with zoho mail. Here is the result.

Note : zoho mail opens a new browser window for every compose. I used IE 7 and Firefox 3.

	Firefox	Internet Explorer
System memory before opening browsers	484 MB	484 MB
After opening browser	515 MB	506 MB
After opening zoho mail	546 MB	532 MB
After opening compose window	556 MB	542 MB
After opening compose window 2nd time	562 MB	543 MB
After opening compose window 3rd time	570 MB	541 MB
After opening compose window 4th time	583 MB	541 MB
...	...	...
After opening compose window for some more times	622 MB	541 MB

Enough care has not been taken in firefox to clear-up memory after a window is closed (or some add-ons should be causing this madness). When I tell 'firefox consumes more memory' or 'memory is not handled well in firefox', it is not a new story. But there was lots of buzz before the release of firefox 3 that lots of work has been done to handle the memory issues, but just not good enough. I use a laptop with 1 GB RAM. People using older laptops should suffer with firefox.

May be fast is not enough.

netbeans creates problem on system hybernation ?

1. When the system goes into hybernation for a long time say - around 7-10 hours, netbeans in my system begins to pixellate. When I scroll using mouse, multiple instances of the mouse pointer is seen on the screen and it persists (image shown). This was existing for a long time.


Another problem i noticed today made me write this post.

2. Even new files are not opening after hybernation.

Even netbeans restart is not a solution. I need to restart windows.

Is there others who are having the same problem? Or am I the only one?

Crimson text editor for windows - a free, feature rich, cool, simple editor

Crimson editor is a free, feature rich, cool, simple text editor for windows.

I am using only crimson editor to edit all text files like .java, .jsp, .xml, .bat etc.

It has many advance features like :

1. Macro recording and replay
2. Opening a remote file using ftp
3. Collective save

and so many other

User experience is made much simpler with say a [ctrl+X] remove the entire line if you have not selected anything in that particular line and many other similar features.

For example if you want .jspf files to follow the coloring format of jsp, you can specify so in Tools >> Preferences >> Syntax.

Explore it more for yourselves. It is available for free.
