Logan’s Lab

Ummm, is that the right name for this place? Miller thought it was. Anyway. It’s a collection links to textures and blender tutorials (with a SecondLife/Open Simulator bias) and other useful things that I need to remember how to do and where to find them. Occasionally I might even write a tutorial or two of my own.

Rubber Band Panning

Neat trick to help stop shaky cam. You could probably use this with a space navigator too. http://youtu.be/Fj6fMcJ18aA

Bash One-Liners

http://www.bashoneliners.com/ – Exactly what it says on the tin.

Among our favourites were:

• Do something in another directory without going there
  for example: (cd /tmp; tar c . ) > tmp.tar
• Find the target path a symlink is pointing to
  for example: readlink /etc/rmt
• List or edit and re-execute commands from the history list
  try: fc –help
  
• Repeat the previous command but with a string replacement
  for example: mysql -h msyql.somewhere.com -u someone -p somedatabase
  …ooops, I put msyql.somewhere…. instead of mysql.somewhere…
  If I type ^msyql^mysql and hit enter and the typo is substituted for the correction in the previous command.

MP3 to OGG Vorbis

We all know that it’s not a good idea to convert from MP3 to Ogg, but sometimes, when you have to, this might help:

mpg321 input.mp3 -w - | oggenc -o output.ogg -

Removing repeating characters (PHP)

In this case it was offending commas, but you could adapt this to most things.

$my_string = ereg_replace('\,{2,}', ',', $my_string);

For a proper explanation, see http://randomdrake.com/2008/04/09/php-and-regex-how-to-replace-or-remove-a-repeating-character/   Thank you :c)
