Two (or three) powerful iterators

If you have some experience working with Ruby you probably had to deal with collections. Collections can be tedious. But TTR (Thanks To Ruby) we have a large arsenal to deal with them!

In this post I'll show you two Ruby iterator methods I really love, thanks to its simplicity and beauty.

My whimsical example

aras-p

// Just before switching jobs:
// Add one of these.
// Preferably into the same commit where you do a large merge.
//
// This started as a tweet with a joke of "C++ pro-tip: #define private public",
// and then it quickly escalated into more and more evil suggestions.
// I've tried to capture interesting suggestions here.

Erlang Tracing: more than you wanted to know

Rough Outline

• What can be traced?
• How can trace events be specified?
• "match specifications": twisty passages, all alike
• WTF, can I just use DTrace and drink my coffee/beer/whisky in peace?
• Trace delivery mechanisms: pick one of two
