knife cookbook site install fails

I assume due to very old, previously installed vendor branches. Do the following:

Cancel the merge the failed command put you into:
git reset --hard HEAD

Delete the problematic vendor branch:
git branch -D chef-vendor-

ATTENTION make sure you did not modify the vendor branch yourself - you'll lose those changes!!!

Switch between spec and source in Sublime Text 2

Install the RubyTest Package

Then you can use

CMD + .

to switch between the spec and the rb file.

Delete a remote branch with git

Delete the local branch

git branch -d branch_to_delete

Delete the remote branch:

git push origin :branch_to_delete

NOTE Make sure you put the colon in front of the branch name

Sublime Text 2 on the OS X Command Line

To use Sublime Text 2 as command line editor, you need to create a symlink:

If installed via Homebrew Cask:

ln -s "/opt/homebrew-cask/Caskroom/sublime-text/2.0.1/Sublime Text" /usr/local/bin/subl

or, if installed manually:

ln -s "/Applications/Sublime Text" /usr/local/bin/subl

And if you want to use it as your default editor e.g. for git status messages, set your EDITOR environment variable like this:

vi .bashrc

export EDITOR='subl -w'

Change Time Format when using ls on Mac OSX

If you want to display the timestamp of a file e.g. in ISO format when using ls on OSX, then you need to install the coreutils e.g. using homebrew

$ gls -l --time-style=long-iso

to display something like this:

-rwxrw-rw- 1 root wheel 433440000 2007-06-27 20:03 Clip 01.dv

ls -l produces:

-rwxrw-rw-  1 root  wheel  433440000 27 Jun  2007 Clip 01.dv

Ext3 on Mac OSX Lion

To be able to read ext3 formatted disks on Mac OSX Lion (10.7) you need to install a current FUSE implementation (macFUSE is discontinued, but there are several newer projects):

Then, you need to install the filesystem itself. The fuse-ext2 is just right (and supports ext3 as well):

Enable Versioning on Amazon S3 bucket using ruby

If you want to enable versioning support for an Amazon S3 bucket, you can use the fog gem.
