(Ruby) Detect the first and last iteration of a loop in Ruby

Fri, 20 Feb 2009 13:44:51 GMT

It's great that, at the times I really need it, I can ask for Ruby help on `#nyc.rb`: how can I detect the first or last iteration of a loop in Ruby or Rails? what sort of loop? an array loop? or something else? f == array.first? in case of an array you want #each_with_index yah each_with_index would do it, thanks much I'm looping through an array printing LIs and I want to apply css classes to the first and last LIs respectively

(Bash) Scrape Google from the command line

This code is POC only -- actually using it would violate Google's TOS, which forbids scraping. It is published here for educational value only. Hypothetically, the following command should return a list of the top 500 or so hits in Google for onemorebug.com. The results will be prepended with digits, followed by a dot and some whitespace (Lynx adds these). _You must have Lynx and Wget installed on your system for this to work._ Keep in mind that *nix shells don't like it when you double-quote strings, see the comments.
