# Here a few bash one-liners that helped me analyze / fight a weak DOS attack against debuggable.com. Mostly for future reference.
# The attacker was opening lots of tcp connections without sending data, I believe it's called a SYN flood, see: http://tools.ietf.org/html/rfc4987#section-3.2

# Step 0: Check what is going on at port 80
$ netstat -tan | grep ':80 ' | awk '{print $6}' | sort | uniq -c

# Public: generates a mixable singleton implementation dependent on a model key.
# Once you mix it into a model, your model gains an .instance method that will
# generate an object and cache it. Further calls to the .instance methods will

#
# key - The name of the attribute we use to index instances. Defaults to "id".
#
# Example
#
#   # Called without arguments uses the "id" as key.

vimcov

Vimcov runs a Ruby script and opens Vim marking the lines that were actually run.

This could be useful when debugging long methods with lots of branching -- instead of abusing puts, you can just use Vimcov and you're good to go.

It runs only in Ruby 1.9.x.

Future versions will include more tight integration with test runs or Rails or whatever.
