Be careful! ./ and source are not quite the same.
./script runs the script as an executable file, launching a new shell to run it
source script reads and executes commands from filename in the current shell environment
Note: ./script is not . script, but . script == source script
source command executes the provided script (executable permission is not mandatory) in the current shell environment, while ./ executes the provided executable script in a new shell.
source command do have a synonym . filename.
To make it more clear, have a look at the following script, which sets the alias.
alias myproject='cd ~...

It's not an option – it's the device name.
Remember that the syntax for mount(8) is:
mount [-t fstype] [-o options] device mountpoint

When in doubt, the best thing to do is use the info command:
[root@abc ~]# info source

Do yourself (and your loved ones) a favor and move out of manual system configuration as soon as possible!
You should start using system configuration management software.
The original use case for such software was management of large number of hosts (for some definition of "large"). However the underlying premises hold for the management of even a single ...
I fully agree that, no matter how fast your RAM is, having 4GB or less will not give you the best experience, so a ceiling score of 5.9 is understandable. Granted, "Memory ops per second" is a bit misleading since other factors come into play here (like the amount of RAM) so perhaps they should have kept it even simpler (never thought that was ...

There's a compiler called asp for creating such files available here.
The problem with these now is that terminals are just too darn fast. This technique was used with slooow serial or dial-up connections. The techniques relies on sending a really large file consisting of text, carriage returns and sometimes newlines.
You can enjoy these files today by ...
In terms of tools, you may take a look at this page which is about automating system administration using open source configuration management tools (USENIX 2010 conference in Boston which hosted the first Configuration Management Summit):
The wikipedia related page is also useful.

The download location changes every time you start the download.
find /private/var -name Xcode.SDK.iPhoneSim*
will reveal the download directory.
The download is restarted every time you click "Install", that is, any previous download is discarded (what a waste with 600 MB+ file size).
Although the downloaded file is a DMG, I still don't know how to ...
I, too, use Windows XP and encountered the same problem, which was very irritating since I tend to use Python's Help file a lot. After a lot of fiddling around and experimenting I was able to fix it up and it now looks like this:
This was accomplished by adjusting two of the settings under the Options / Internet Options... menu item. The first was to change ...
