If you take version 4, stop the first while loop once the size is at most 32, and then do linear search from there, it's faster (on my machine). For example, version 4 is 102ms and…

Almost a year ago I tried to see how short of a cyclic tag system I could make in Ruby. The result: https://github.com/elitheeli/stupid-machines/blob/master/sho...

But what's in that string? That still counts. What I should have done was put an additional restriction on what IO is available. Otherwise, something like "eval `cat f`" or somethi…

Sorry, you're totally right. My bad.

When I say "Turing complete", I mean Turing equivalent to a Turing machine. Since there are infinitely many Turing machines but I'm pretty sure humanity has access to a finite amou…

TeX is very Turing complete. As is Java sans semicolons, C macros, and many other things that probably shouldn't be. Right now, I'm trying to figure out what the minimum number of …

I tried to do a little bit better of a job explaining it above. I was caught off guard... I intended to post this in a few days with a proper explanation.

Is my MacBook Pro any more Turing complete? All of the memory came with it. There's no way to expand the memory as it's running.

Way to steal my karma.... :) As the original author of this, I was going to put it into a much more presentable state before showing it off here. For those confused, here's a prope…

ActiveRecord (Rails) provides counter caches for this instance. There are also gems that will analyze the queries your ORM performs to tell you which ones you should optimize. I te…

Thanks, we'll try to get these fixed ASAP.

I'd also like to thank everyone in advance for feedback. In exchange, here's a clickable link: http://statusdot.com
