OS X Yosemite Messages database merger

Early betas of OS X Yosemite had a bug where the library of old messages wasn't migrated. Instead a new library was created and all old messages were gone.

The bug has been fixed, but if you were affected, you still have two separate libraries. This script merged them for me. Use it at your own risk! You might end up worse than before. Backup everything beforehand. Twice.

This is what your ~/Library/Messages folder will look like if you're affected:

• chat.db

JavaScript and Object Models

A "choose your own adventure" story

JavaScript is has both object-oriented and functional heritage, thanks to its two parents: Scheme and Self.

It provides first class functions and makes it simple to compose these function objects into bundles of awesome. Even though I'm an OO "true believer" at heart, I find myself composing my code using functional concepts, and use the OO approach where there's a clear benefit or where I feel that it's the best way to communicate the interface.

Object-oriented software design is by no means the only way to do software design, but it's been an immensely successful model for a very long time now, and provides a clear and well-understood mental model for thinking and communicating about software. Lots of good ideas like encapsulation, delegation, traits and composition fit well into OO design.

Git Submodules basic explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:

• Separate big codebases into multiple repositories.
