Why Not SSL Everywhere?

• Cost
• Setup
• Performance impact
• Mixed-content warnings
• Third-party content (ads, analytics)
• User-embedded content
• CDNs (CNAMEs)

encode.c

Simple exercise for learning C:

• Reads text from STDIN
• By default, rotates all text by one character ("abc" => "bcd")
• Prints to STDOUT
• If the "-n [number]" flag is supplied, rotate by that many characters
• If the "-d" (decode) flag is supplied, rotate in the opposite direction
• If the "-f [filename]" flag is supplied, read from that file rather than STDIN

Rails 3.1 Asset Pipeline

• The new asset pipeline in Rails 3.1 makes assets first class citizens in Rails
• Assets now in app/assets rather than public (also lib/assets, vendor/assets)
• Asset files can inline other asset files using requires
• Asset packages are defined in manifests
