Ubuntu cheatsheet pages

In my research to fix problems, I have often run across one page which does an excellent job of providing a solution to my problem. Often, this page is actually official Ubuntu documentation, but usually I have a hard time finding it. Detailed here is a list of extremely useful URLs and what they are about:

AMD64/FirefoxAndPlugins	extremely useful page showing how to install 32-bit firefox and java on x64 Ubuntu
Fonts	Fonts page includes large .fonts.conf text, for making all those pesky fonts look sharp, clean, and windows-like
CronHowto	Handy reference on setting up CRON tasks.
How to mount disks

Hope this helps someone, and if not, I know I will be going back through this list when I need help.

Runescape HD on (K)Ubuntu

One of the games I play is Runescape. It is a 3d Java MMORPG, and has both software-rendered(SD) and hardware-rendered(HD) versions. One of the problems I have so far had in switching my main computer to Ubuntu is that I couldn't get HD working - SD takes up way too much CPU and is not nearly so nice graphics wise. I would simply get a "Graphics mode not supported" error.
I did some research, and found that the problem is that I was using a 64-bit version of Ubuntu. Runescape only works on 32-bit Java, at least on Ubuntu.

So, what I did is as follows:
1. Installed the KUbuntu 9.10 RC from Here
2. I used the "Hardware drivers" control panel to install a proprietary graphics driver - NVIDIA in my case
3. I then followed the tutorial for installing 32-bit Firefox and plugins here.

I restarted, then opened up a terminal and typed "firefox32 &". Firefox 32bit started, and I was able to run Runescape.

There are two "issues" at this point:
One, you are probably going to want to create a shortcut to "firefox32 &" if you use it a lot.
Two, there is a minor issue involving the GTK libs - Firefox 32 is looking for the 64 bit libs and failing to load them, so the chrome is a bit blocky. I tried one fix, but haven't gotten anything working yet.

Hope this helps someone!

Linux Cheetsheet

This is a simple cheatsheet of stuff I am using a lot, administrating a CentOS4 server. Also some stuff I use with Kubuntu on my laptop.

Common options:
- c=create, x=extract, t=list, r=add more files to an archive
- z=Gzip

Find
syntax: find *folder* *options*
-name '*pattern*' - Name pattern, * is OK.
-(i)regex 'pattern' - (case insensitive)regular expression.
-size *number*[kMG][+-] - searches for files with *number* size(suffix k, M or G for kilobytes, Megabytes, Gigabytes), and if you add a + or - you will get all files larger or smaller than size respectively.

Chown/Change Owner
syntax: chown [-R] *newowner* *filenames*
The -R option makes Chown change the permission on files that are in the sub-directories of the directory that you are currently in.
