• 10 Ruby One Liners to Impress Your Friends – Someone came up with a list of 10 one-liner examples that are meant to showcase Scala’s expressiveness. A CoffeeScript version quickly emerged, so I thought I’d publish a Ruby one. I find Ruby’s syntax to be a bit cleaner than Scala’s, but the substance (at least as far as these examples are concerned) is relatively similar.
• Ruby development for system administrators | Linux User – Most Linux and UNIX system administrators use a diverse mix of shell scripts and tools like grep, awk, cut and so on. The classical approach has proven its merits, but these scripts are generally not easy to read or to maintain. One solution is to use a real programming language for system administration tasks. In a complex environment, system administration can become much easier with a real programming language instead of shell scripts. Traditionally, Perl has been very popular among sysadmins, but some people maintain that this is not much better than shell.

  In this article, we choose Ruby, a feature-rich but simple object-oriented programming language known from the popular web application framework Ruby on Rails. T

• Useful commands for Windows administrators – Managing a Windows 2000 Active Directory with about 100 servers, over 1500 computers and 35 sites, the following commands often helped me answer questions or solve problems.
  Most commands are "one-liners", but for some I had to make an exception and go to the right directory first.

  These commands could all be used in batch files, though some may need some "parsing" with FOR /F to retrieve only the required substrings from the displayed information.

• I tool "segreti" per aumentare la sicurezza di Windows – Non tutti sanno dell’esistenza di un set di strumenti che, avviati dalla linea di comando, consentono una gestione puntuale di diversi aspetti di security[…]
