Adds in the missing 480px-797px breakpoint range to Bootstrap 3 for SASS
// Bootstrap Mid-Small - col-ms-* - the missing grid set for Bootstrap3.
//
// This is a hack to fill the gap between 480 and 767 pixels - a missing range
// in the bootstrap responsive grid structure. Use these classes to style pages
// on cellphones when they transition from portrait to landscape.
//
// Contains:
// Columns, Offsets, Pushes, Pulls for the Mid-Small layout
// Visibility classes for the Mid-Small layout
// Redefined visibility classes for the Extra Small layout

Rsync over SSH - (40MB/s over 1GB NICs)

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

  • a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
  • H: preserves hard-links
  • A: preserves ACLs

Simple spam protection for email addresses using jQuery
/* Simple spam protection for email addresses using jQuery.
* Well, the protection isn’t jQuery-based, but you get the idea.
* This snippet allows you to slightly ‘obfuscate’ email addresses to make it harder for spambots to harvest them, while still offering a readable address to your visitors.
* E.g.
* <a href="mailto:foo(at)example(dot)com">foo at example dot com</a>
* →
* <a href="mailto:[email protected]">[email protected]</a>
