I might be the last one on earth that still runs a Rails 1.1.x app. This time the ancient one dodged a bullet.

Tried it on a Mac mini of age but still a Core 2 Duo. It was very slow in Google Chrome. If it's moving smoothly on more modern computer I guess It's time to upgrade.

On another note, I believe that this is why native still is around.

In Ruby:

  # Ethiopian Multiplication
  # usage: ruby em.rb 673 7
  m, n = ARGV.map(&:to_i)
  product = 0
  while m >= 1
    puts "%4d : %4d %s" % [m, n, m.even? ? "Ignore" : ""]
    product += n unless m.even?
    m = m / 2
    n = n * 2
  end
  puts "Product: #{product}"

If I'm not mistaken he also mentions LINQ wich is a wonderful extensions of C# and the .NET Framework. It feels like LINQ and Clojure could be a interesting match.

That was what I thought he was aiming for to but then he, out of nowhere, suddenly praised PHP. I'm 99% sure that I don't have to check out PHP again to see if it's really something about it that I've missed.

I wish there was a video of "The Mother of All Demos" where you could actually read the text.

Wonderful slides! I hope there will be video further on.

I didn't like "It is critical to remember that play is not exercise." and to improve it I would like to add something like "But it's totally fine if your exercise feels like play. If your exercise is fun it's so much easier to do".

I'll get straight to the elephant in the room and I'm even ignorant enough to ask it before I tried to find out myself (though at gun point I would lean more towards one that the other). Is it homoiconic?

Unfortunately it's divided in chapters without any indexing so it can get a bit confusing since you most probably aren't going to be able to watch them in the order he presented them. Still worth it!

It depends on how many servers you are willing to run. When you have 500 million users, and a decent amount of them, accesses your site multiple times a day, CPU cycles per request starts to count.
