Changing "message:" protocol handler from Sparrow back to Mail.app

January 25, 2012
After using Sparrow for a while, I have decided to switch back to Mail.app. However, even after setting my default email client to Mail.app, all my message: links (for example, from messages dragged from Mail.app into Things) were opening in Sparrow.

After some experimentation, I figured out what happened: I switched the default email client from Sparrow to Mail using Mail's preference panel:

Pastedgraphic-1

Apparently this switches the application for the mailto: protocol, but not for message:, nor for .eml files. The solution was to use Sparrow's preference panel to set it again as the default email client, and then disable it. Then Sparrow correctly sets all the protocol handlers back to their default values.

How to remove a subproject/submodule to a git-svn repository

January 25, 2012

To sum up, you delete the offending directory and then run something to the effect of

git filter-branch --index-filter \
'git rm --cached --ignore-unmatch path/to/the/formerly/misbehaving/module'

I accidentally added another git repository to a git-svn repository, which makes it die when trying to push the changes. This technique helped me fix it. Documenting mostly so I remember when it happens again sometime.

nwdiag generates network-diagram image file from .diag file. .diag file is similar to DOT file (graphviz’s).

You can get diagrams like this.

Very useful, like Graphviz but specifically for network diagrams. You can probably obtain the same result with Graphviz with the appropriate amount of dot magic, but nwdiag makes this very easy. Other useful graph types in sister projects: http://blockdiag.com/en/index.html

How One Bit of Stupidity Could Have Brought Down a Multi-Million Dollar Media Company | Peter Shankman

the man sitting next to me was reading proprietary information, information that could be very, very damaging to this company if in the wrong hands, and he couldn’t have cared less about it

Fascinating, scary story. It's amazing the things people do in airplanes (particularly on their laptops/iPads/phones) as if no one was watching them. Situational awareness is very important.
