LESS, A/B, Browsers, Ruby Interpreters, and More

The weekly round up:

• I’m getting ready to start a project that is going to be using LESS for CSS. Think Vitamin did a podcast covering some of the new approaches to writing CSS.
• Deck.js is a JavaScript-based presentation tool (you’re a presentation tool) – kind of a cool alternative for PowerPoint or Keynote, albeit much simpler.
• 37signals wrapped up their series on A/B Testing.
• Similarly, A List Apart published an article introducing A/B testing.
• Accounting.js is a JavaScript library that makes it easy to deal with currency and number formatting.
• Smashing Magazine ran a piece on the Semantic Grid and its place in web development.
• How Browsers Work – highly recommended reading for anyone doing serious web development work.
• Pry is an alternative Ruby Interpreter and Ryan Bates gave a nice intro screencast on it.
