Firefox unresponsive scripts warning – fix

Firefox 1.5 brings up more unresponsive script warning on sites that use heavy Javascript like Gmail than the previous version. To fix this problem, you just have to change the configuration.

  • Type about:config in the address bar and you will get the hidden configuration page – similar to the windows registry editor.
  • In the filter box, type dom.max_script_run_time. This will filter the options and will display only the dom.max_script_run_time.
  • Right-click it and choose Modify. A box pops up. Change the number to something bigger like 20. This is the maximum time a script can run before Firefox considers it

Ubuntu on PowerPC

Some days ago, I wanted to try Ubuntu for PowerPC in our iMac labs and so I popped the CD and rebooted. But, I didn’t know how to make the system boot through the CD. After some searching, I found out a way to boot through the CD.

Hold down the c key when booting the computer or Command-Option-Shift-Delete key combo. You will get a menu where you can choose from which media boot the computer. It is just so easy to do. Have anyone installed Ubuntu on their apples? Tell me about your experiences.

Kill an application in KDE

New Linux User has a very useful article about how to kill an application that misbehaves in your KDE.

When in KDE, if an application stops responding, just press Ctrl-Esc and it brings up the KDE process table. This table lists all the running processes and you just have to select the application that is not responding and have to click the kill button.
Actually, people say that Linux doesn’t hang like Windows. Yes, that is absolutely true, but the Graphical User Interface (desktop environment) has its own bugs and it is still not so stable to run any kind of app without crashing. Whatever happens to the desktop environment , you could always use the command line interface (CLI). CLI users always boast of this power and uninterrupted usage. This is also an important thing why Linux has better uptimes than Windows machines.

Make Firefox 1.5 work with all extensions

The most common problem with Firefox1.5 is that most old extensions don’t work. There is a workaround for this though. A simple modification to the Firefox Configuration will do the trick.

  1. At the location bar type about:config. This will show a list of firefox preferences.
  2. Right click on the list and select New > String. Enter

Shell Prompt – An Overview

Now I have decided to write articles which will help the new linux user to do things the pro-way i.e. using the shell.
There are many different shells available with the GNU/Linux system.
Sh – The old UNIX shell
Bash – Bourne Again Shell – rewrite of the sh shell
csh – C Shell – similar to C funtions
and so on.

Most GNU/Linux systems come with the default Bash shell and it can be recognised by a $ prompt or a # prompt.
The $ prompt indicates that you are logged in as an ordinary user.
The # prompt indicates that you are logged in as a root user. This is most powerful user, so just be careful with it.
You can log in to the root user at anytime by using the su command.
I think this gives a basic overview of the shell. I have decided to start writing a series which will teach a new command everyday.

Restricted Formats – Install Packages

In Ubuntu, many formats are not available as there are licensing or patents issues with such formats. Such examples are MP3s, which require about 75cents for every player that plays MP3 files. Other formats that are not available CODECs for DVD playback, Java, Realplayer, Flash, etc.
You can install them by following the steps in the the wiki page of Ubuntu.
