Fix OpenSSL certificate errors on Ruby 2.0
View OpenSSL

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('')"
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.

Want to find out what changes were introduced by a particular merge commit? Hey, so do I! ALL THE TIME. These aliases will do that.

# `git merge-log` shows the commits that were introduced in a given merge
# `git merge-diff` shows the actual changes that were introduced by a given merge
# Both commands accept an optional commitish; if ommitted, the last merge commit is used

Fibur is a library that allows concurrency during Ruby I/O operations without needing to make use of callback systems. Traditionally in Ruby, to achieve concurrency during blocking I/O operations, programmers would make use of Fibers and callbacks. Fibur eliminates the need for wrapping your I/O calls with Fibers and a callback. It allows you to write your blocking I/O calls the way you normally would, and still have concurrent execution during those I/O calls.


Say you have a method that fetches data from a network resource:
