In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

http://techcrunch.com/2007/08/11/facebook-source-code-leaked/

It became a big deal:

The two files are index.php (the homepage) and search.php (the search page)

# Mac OS X webarchive is a binary format of a plist file. You can extract the contents manually:
#  1. convert the plist file into XML by "plutil -convert xml1 file.webarchive"
#  2. parse the resulted XML file by some XML parser
#  3. decode "WebResourceData" by Base64.decode64(data) in each key
#  4. save the decoded content into a file indicated by "WebResourceData"
# Thankfully, the plist library can take care of annoying steps 2 and 3.

The reason why you might get certificate errors in Ruby 2.0 when talking HTTPS is because there isn't a default certificate bundle that OpenSSL (which was used when building Ruby) trusts.

Update: this problem is solved in edge versions of rbenv and RVM.

$ ruby -rnet/https -e "Net::HTTP.get URI('https://github.com')"
net/http.rb:917:in `connect': SSL_connect returned=1 errno=0 state=SSLv3
  read server certificate B: certificate verify failed (OpenSSL::SSL::SSLError)

You can work around the issue by installing a certificate bundle that you trust. I trust Mozilla and curl.
