Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

Create a shortcut on your desktop and insert the above command.
I don't know if you've used sqsh before. But it has a handy feature that allows you to switch into vim to complete editing of whatever complicated SQL statement you are trying to run.
But I got to thinking -- why doesn't bash have that? Well, it does. It's called '|'!
Seriously, I'm pretty sure this flow of commands will revolutionize how I administer files. And b/c everything is a file on *nx based distros, well, it's handy.
First, if your ls is aliased to ls --color=auto, then create another alias in your .bashrc:
alias lsp='ls --color=none'
Now, let's say you want to rename all files that begin with the prefix 'ras' to files that begin with a 'raster' prefix.
You could do it with some bash substitution. But who remembers that? I remember vim macros because I can remember to press 'qa' and how to move around in vim. Plus, it's more incremental. You can check things along the way. That is the secret to development and probably the universe. So type something like:
lsp | grep ras
Are those all the files you need to move? If not, modify and re-grep. If so, pipe it to vim.
lsp | grep ras | vim -
Now run your vim macros to modify the first line. Assuming you use 'w' and 'b' to move around, etc., it should work for all lines. Hold down '@@', etc., until your list of files has been modified from
mv ras_a.h raster_a.h
mv ras_a.cpp raster_a.cpp
mv ras_b.h raster_b.h
mv ras_b.h raster_b.cpp
then run :%!bash
then run :q!
then be like, whaaaaa? as you realize your workflow got a little more continuous. maybe. YMMV.
Could use your ssh bash history if your known_hosts are hashed and you want to keep it hashed
Delete a user?s password (make it empty). This is a quick way to disable a password for an account. It will set the named account passwordless.
it recursively searches your project's directories and sum the lines of every source [.c or .h]. Then it gives you the total.
It is an easy method unzip a file and copy it to remote machine. No unziped file on local hard drive
Get windows version with servicepack and hostname
Paste what you previously wrote in INSERT MODE, for example:
1. Write 'foo' in INSERT MODE
2. Return to NORMAL MODE
3. Press "." and it will paste 'foo'
when you can do it , avoid pipe
A script that checks if your environment is correctly configured for using cobbler.

Also works with files:
To decrypt use the -d option:
echo SGVsbG8gd29ybGQK | base64 -d
For those files in current folder that would be shown in `ls *ext`, for some extension ext, move/rename that file removing the .ext suffix from the file name.
It uses Bash's parameter substitution, as seen in
(for analog use in prefix, see http://tldp.org/LDP/abs/html/parameter-substitution.html#PSOREX2 )
combines mkdir and cd
