Web excursions: October 22, 2011 - October 24, 2011

Links of interest from October 22, 2011 through October 24, 2011:

• 10+ .htaccess snippets to optimize your website
  Mostly old standbys, but a few very handy snippets.
• Screenfly by QuirkTools
  Best-looking and most flexible tool I’ve seen for testing responsive web design on multiple devices/resolutions.
• KeyStroke
  This Safari extension is amazingly useful, especially due to the fact that it’s so easy to toggle on and off. It provides customizable single-key shortcuts for a wide array of browsing activities. In combination with Vim Like or gleeBox, it’s nearly perfect.
• List.js - Add search, sort and flexibility to plain HTML lists
  Make plain HTML lists flexible, searchable, sortable and filterable with 7k of cross-browser JavaScript.
• A bookmarklet to create the HTML5 cache manifest
  A bookmarklet for creating the cache manifest required for HTML5 offline versions of sites.
