Brett Terpstra has released Marked 2.2 (Build 822), which adds a couple of new features to the Markdown previewer. According to this blog post, the latest build improves how Marked handles opening external files that aren’t recognized (suggesting to open in a default app instead of just providing an error message), asks whether you want to open links in the current window or a new one, and improves how it handles YAML (the “human friendly data serialization standard for all programming languages”). Marked also now features MathJax configuration updates, syntax highlighting improvements, and a fix for MultiMarkdown metadata like “Base Header Level” and “Quotes Language” not being recognized. A quick update to Build 823 fixes a minor bug. ($11.99 new, free update, 16.3 MB, release notes)
Smarter Parental Controls
If you've been using the parental controls options in Mac OS X to lock your child out of using a particular computer late at night, but would like to employ a more clever technique to limit Internet access, turn to MAC address filtering on an Apple base station.
To do this, launch AirPort Utility, select your base station, and click Manual Setup. In the Access Control view, choose Time Access to turn on MAC filtering. You'll need to enter the MAC address of the particular computer, which (in 10.5 Leopard and 10.6 Snow Leopard) you can find in the Network System Preferences pane: click AirPort in the adapter list, and click Advanced. The AirPort ID is the MAC address.
