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,…):

Newer versions of Dropbox let you choose the location for your Dropbox folder. If you use script to put things into your Dropbox folder (todo list, screenshots, torrents etc.) but have the Dropbox folder in different locations on your other computers this lets you use the same script on all systems without having to tell it where the Dropbox folder is.
Similar output to using MySQL with the \G at the end of a Query. Displays one column per line. Other modes include:
Query results will be displayed in a table like form, using whitespace characters to separate the columns and align the output.
-html Query results will be output as simple HTML tables.
-line Query results will be displayed with one value per line, rows separated by a blank line. Designed to be easily parsed by scripts or other programs
-list Query results will be displayed with the separator (|, by default) character between each field value. The default.
From inside the command line this can be also changed using the mode command:
.mode MODE ?TABLE? Set output mode where MODE is one of:
csv Comma-separated values
column Left-aligned columns. (See .width)
html HTML code
insert SQL insert statements for TABLE
line One value per line
list Values delimited by .separator string
tabs Tab-separated values
tcl TCL list elements
This command defragment the SQLite databases found in the home folder of the current Windows user.
This is usefull to speed up Firefox startup.
The executable sqlite3.exe must be located in PATH or in the current folder.
In a script use:
for /f "delims==" %%a in (' dir "%USERPROFILE%\*.sqlite" /s/b ') do echo vacuum;|"sqlite3.exe" "%%a"
Filters out all non-insert SQL operations (we couldn't filter out only lines starting with "INSERT" because inserts can span multiple lines), quotes table names with backticks, saves dump to a file and pipes it straight to mysql.
This transfers only data--it expects your schema is already in place. In Ruby on Rails, you can easily recreate the schema in MySQL with "rake db:schema:load RAILS_ENV=production".
For Mac OS X users only
Sqlite database keeps collecting cruft as time passes, which can be cleaned by the 'vacuum;' command. This command cleans up the cruft in all sqlite files relating to the user you have logged in as. This command has to be run when firefox is not running, or it will exit displaying the pid of the firefox running.
