Here’s a nice trick for turning long integers into much shorter “tinyurl” style strings.
12345.to_s(36) => "9ix" "9ix".to_i(36) => 12345
Technically what’s happening here is Ruby is turning the Base-10 Integer into a Base-36 alphanumeric representation of that number.
This is the trick that reddit.com uses for creating smaller urls that correspond to an integer-based record in their cassandra database.
Here’s another trick for ya- You can use the same method to create shortented URLs that are consistent and unique:
"http://chris3000.com".hash.abs.to_s(36) => "vaniclb8g7wm" "http://www.google.com/?q=this+is+a+long+query+in+google".hash.abs.to_s(36) => "kod59h8xj2sg"
