Bash Productivity Enhancers
Jan 20th
Bash is an extremely powerful shell, but its shortcuts are not readily apparent. Here are a few shortcuts and tips that I’ve noticed many (already proficient) bash users are not aware of. You can also check out Improved Bash History and More Useful Bash/Terminal Settings for more ideas for improving your bash productivity.
Bash Navigation ShortcutsWhen editing a long command, there are quite a few navigation and editing shortcuts. By default bash typically operates in emacs mode.

I got tired of the performance issues I was having so I’ve migrated my blog to a Slicehost slice (512MB). Hopefully nothing is broken, but if you notice something let me know. Everything should load more quickly and consistently going forward!

A Cold Canoe Ride Big Horn Sheep Ice ColumnsMy Trip To The TSA Security Theater
Jan 11th
Having just returned from a trip to Canada I have now experienced the new TSA security theater1 for flights inbound to the US from abroad. Hopefully your own experience will not mirror mine, but if these restrictions stay in place this post could be helpful to some.2

I’ve put quite a few custom CSS tweaks in already, some of which I’ve listed below. Others who use More >
