Ruby Procs And Lambdas (And The Difference Between Them)
As you know, I am a big believer in knowing the basics. I find it is especially valuable to go back to the fundamentals of whatever skill you’re trying to master periodically, as you gain more experience. Somehow you’re always able to extract something valuable from the experience due to the extra insight you’ve acquired along the way. Recently I’ve been looking more closely at some Ruby concepts

aussie bloke: Eval Expression service for OS X
Eval Expression is a Mac OS X service to evaluate the selected text of any text field as a Ruby expression.  My instinct was to choose Perl, however Ruby offers binary in addition to decimal, hex and octal numerical literals.  The service becomes infinitely more useful if you assign it a global shortcut in Keyboard preferences.  In my case I assigned a combination that seemed obvious, ⌘= It came a

A Hint of Hubris
Ruby is a highly dynamic language with impressive capabilities for runtime redefinition of classes, objects, methods, and variables. Haskell, on the other hand, is a purely functional language that confines mutation within a sophisticated static type system. Given their many differences one or the other may be more suited for whatever problem you might be working on (see polyglot programming), but

Using the Apple remote in Ruby
After playing with iremoted and Ruby’s IO.popen I guess I am convinced that Ruby really works as a glue on many levels. So, using iremoted and capture Apple remote commands in the terminal it is trivial to use the remote to control a Ruby application. Of course, calling OS commands isn’t limited to Ruby. Here is a minimal dungeon game which you control with the apple remote. If you ever manage to
