Solutions to Firefox using too much CPU on Ubuntu Linux

Ubuntu decided several months ago to forgo its policy of sticking with Firefox 3.6, and go with the latest versions from Mozilla.

With Firefox 13 running on Ubuntu 10.04, I had good performance, and did not suffer from this problem that I am about to describe. The only issue I faced was excessive disk activity and that was fixed by disabling the FireBug extension. Other than that, Firefox was speedy and responsive.

Arabic on Sony Ericsson Xperia Arc and X10 running Android

A very nice surprise from Sony Ericsson. Even though Android does not have full and official support for Arabic until Android 4.0, their handsets do have very good Arabic support by default, even handsets sold in the USA and Canada.

Arabic in Sony Ericsson Xperia Android phone

If you have Android 2.1 or 2.3 and updated it to the latest update from your carrier, then you do have Arabic support. To check if it works, then just visit BBC Arabic and see if Arabic shows correctly and the letters are connected.

Enabling Arabic keyboard

To enable Arabic typing, you need to press Menu, then select "Language and Keyboard", then under "Keyboard settings" select "Default input", then select "Writing Languages", and check "Arabic". You will then see a language switching icon on your keyboard (the "globe" symbol).

Not only does Arabic work well, the font looks much better than what is in CyanogenMod for example.

This is a a list of Android applications that I currently have on my phone. Some are more often used than others, but all are useful.

These apps are running on my Sony Ericsson Xperia Arc, which has Android 2.3.3 on it. Most of them ran on the Sony Ericcson Xperia X10 as well.

ADW Launcher is a fast and feature rich home application replacement. Use it instead of Sony Ericsson's TimeScape and your phone will feel faster.

Converting Cisco Easy VPN .pcf files to Linux vpnc configuration format

Since I use Linux exclusively, and have to interface with clients using various Windows technologies, open standards are an important aspect of our tech-life. For example, we use OpenOffice to read Word/Excel/Powerpoint files, and so on.

One thing that comes infrequently is the need to login to a corporate virtual private network (VPN) that uses Cisco's Easy VPN.
