Jens Alfke’s Ottoman is a “lightweight, reliable key-value store with multi-version concurrency control.” It looks somewhat like an improved cdb with better concurrency.

Metadata Madness

John Siracusa:

4. The default Launch Services application binding policy should reference both file type and creator metadata, preferring the “modern” representations of each, and falling back to the classic Mac OS representations in their absence. The per-file “ultimate override” setting should be considered first. If that is not set, then the file should be opened by the application that created it. If that application is not installed, then the file should be opened by the default application assigned to that file type.…5. The Launch Services application binding policy should be configurable.

Notebook Batteries


For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Apple does not recommend leaving your portable plugged in all the time. An ideal use would be a commuter who uses her MacBook Pro on the train, then plugs it in at the office to charge. This keeps the battery juices flowing.

Good to know, since I mostly use my MacBook Pro as a desktop. After using it on battery for just a few minutes, it takes 1.5 hours or so to get back to a full charge.
