I'm not sure but I came to think of the HATEOAS constraint of REST.

Here's a Ruby one-liner n=1234567;(1..n).reduce{|t,n|s=i=0;loop{i+=1;s+=rand;break if s>=1};t+i}.to_f/n

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. "ah, actually 1.1.x isn't vulnerable. The issue first arrived in 2.0"…

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 no…

Could you please explain why it would output that?

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 un…

I played with the same kind of hack back in the nineties and then in JavaScript+HTML table in 2001. http://plea.se/me/galen_man.htm (it was hideously slow to scroll down back then)…

1.upto(100){|n|puts [["Fizz"][n%3],["Buzz"][n%5]].inject{|m,e|m=m.nil? ? e:m+=e||""}||n}

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.

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 …

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 o…

Some time ago I read the slides from Greg Wilsons excellent presentation Bits of Evidence. Today I found out that it's on YouTube (see comment). I find it fascinating that the scie…

Neat but it seems the pixel plotting could be optimized but I guess I should keep my mouth shut until I've tried to draw that big with my http://plea.se/me/leif/canvas_leif.html
