Getting a free certificate

This page guides you through the process of obtaining an HTTPS certificate for your site. This is a real certificate, not a self-signed certificate, and works in all major browsers.

The CA which we'll use is StartSSL. They provide basic certificates for free, although will charge for other types, such as wildcard certificates.

Generating a public/private keypair

A keypair can be generated with OpenSSL:

var gistPrefix = 'https://gist.github.com/',
    // Cache document.write so that it can be restored once all Gists have been
    // embedded.
    cachedWrite = document.write,
    body = $('body'),
    // Map each p.gist to an object that contains the paragraph to be replaced
    // and the Gist's identifier.
    gists = $('a.gist').map(function(n, a) {
        a = $(a);
        var href = a.attr('href');

# First, I suppose you have ruby 1.9.1 or 1.9.2
# Open irb. Execute this:
# RubyVM::InstructionSequence.compile_option = { tailcall_optimization: true, trace_instruction: false }
# Note, RubyVM::InstructionSequence.compile_option() doesn't have item :trace_instruction, still, you need to specify it. WTF?
# Also, it doesn't work if you just put it to the script. Don't know why yet. Tell me (@rofh) if you know.

# Then open the file:
# require "./tail-recursive"
# Then execute function:
# fact(30000)
