Native 64bit Java plugin for Firefox, on Ubuntu.

Now there are no more reasons not to install 64bit Ubuntu. First is was Adobe with their native 64 bit Flash plug-in and now Sun has released a native 64 bit Java plug-in.

To install the 64 bit java plugin on Intrepid 8.10:

  1. Download the bin file here
  2. cd /opt
  3. sudo sh jre-6u12-ea-bin-b03-linux-amd64-22_dec_2008.bin
  4. cd /usr/lib/mozilla/plugins
  5. sudo ln -s /opt/jre1.6.0_12/lib/amd64/libnpjp2.so
  6. Restart Firefox

Done!

Ubuntu on MSI Wind with Ralink wireless radio

I just got my wife a new MSI wind netbook. First things first, Installed Ubuntu.

Everything just worked out of the box, except the wireless.

Turns out MSI is using several wireless card suppliers. Mine came with a Ralink card. More specifically the RT2860

The are several ways to fix it, but to keep things simple, I’ll go with debian’s way, which is also the easiest.

  1. Just download and install the following .DEB
  2. sudo apt-get install debhelper module-assistant
  3. sudo m-a a-i rt2860
  4. sudo modprobe rt2860sta
  5. sudo gedit /etc/modules , and append “rt2860sta” at the bottom. (without the quotes).
  6. Save the file, and connect with the Network Manager

Done!

Installing Xmonad on Ubuntu

This is the simplest (I think) that a window manager can get.

From the makers:

xmonad is a dynamically tiling X11 window manager that is written and configured in Haskell. In a normal WM, you spend half your time aligning and searching for windows. xmonad makes work easier, by automating this.

A window manager that is completely different. To leave distractions aside and concentrate on real work, is very hard to beat xmonad. This is simplicity as its best. It Rocks.

By the way, it can co-exist with your other windows managers so you can use it on a per need basis. Just chose it on the login window by pressing F10.

http://xmonad.org/

To install on Ubuntu:

sudo apt-get install xmonad

Be sure to read the guided tour first and learn all the basic stuff here otherwise I guarantee you wont get anywhere.

The least you should learn is Alt-shift-enter to be able to open a terminal and Alt-shift-q to quit
