Fix OpenSSL certificate errors on Ruby 2.0
View OpenSSL fix.md

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.

kvz: "I'm recommending these Mac apps to a colleague who's losing his OSX virginity: https://gist.github.com/1372883. Anything you think I should add?"

Don't forget to look at the suggestions at the bottom, there's some cool stuff in there.

Essential

  • 1Password - password manager. intergrates with Dropbox & all main webbrowsers so you'll never lose a password again
  • Dropbox - a free 2GB folder in your homedir that stays in sync with all the devices you also install it on (linux/windows/mac/ipad/iphone/etc). Useful for backup, collaboration (share 1 folder with others), and keeping important documents with you.

If you add a dir directly under app/

Do nothing. All files in this dir are eager loaded in production and lazy loaded in development by default.

If you add a dir under app/something/
