For <http://bjeanes.com/2009/10/01/code-formatting-in-rss-feeds>:

Firstly, please don't limit your feed to just excerpts. Clicking through to read content is annoying at best (more clicks) and impossible at worst (i.e. offline).

Inline styling of the feed content is a much better idea but still not the best. Markup should be semantic (your current code block are not IMO) and feed readers may not even respect user styles.

I think the markup needs to be fixed so it makes sense semantically. I'm thinking it should be a normal <pre/> with <span/>s for style hooks. To add line numbers, wrap each line in <code/> so we can style each line (unless I'm missing a way to write a selector to match all lines a la ::first-line).

I have quickly thrown together a proof of concept, tested in Safari 4 only. It's roughly styled like your blog with the <pre/> code generated by the TextMate.tmbundle but with manually added <code/> tags. The styling is a good candidate for SASS with all the calculations.

Run VMware Fusion headless at Mac OS system startup.

I heard you like headless VMs on your Mac so I wrote this script for your launchds.

Assumptions

• Tested on Mac OS X 10.6.4 with VMware Fusion 2.0.5 and 3.1.1.
• A interactive user automatically logs into the system at startup. I had some issues trying to get this running without an interactive user logged in. I automatically log in for Airfoil Speakers anyway.
• Your virtual machines live in /Virtual Machines
