bash completion for ruby, rails, gem, heroku etc

I needed (and found) Bash completion for Ruby & co. (gem, rails etc). Sadly this is for Rails 2; I found a more recent Bash completion for Rails 3 project. And there is Bash completion for Heroku as well.

drupal findings

• Drupal upgrade easier (patching)
• Drupal6 WYSIWYG CKEditor buttons toolbar wrap: by a nasty hack into the PHP config code you can automatically group the buttons. array_chunk is our new friend :)
• “a subtheme doesn't necessarily inherit the favicon of its parent theme, [one has] to manually place it in each of their theme roots.”

Solved: Eclipse javadoc hover gone

The problem:

I don’t see the usual javadoc hover in Eclipse IDE.

Cause:

I used the same workspace on different computers, so some file permissions got messed up. This caused an exception in the hover-rendering internals.

Solution:

Regain ownership over whole workspace: (of course while Eclipse is closed)

user@host:/path/to/workspace$ sudo chown -R ${USER}: .

Additional conclusions:

• It’s useful to look for errors in ~/.xsession-errors, that receives the standard error of X windows.
• from man find: -nouser No user corresponds to file's numeric user ID.
• It’s useful to have a place where I can write down these findings ;) I’m pretty sure I once already solved this problem, but then forgot about it.
