A quick-and-dirty way to get the memory usage of the current process in Linux. Read /proc/self/status. The line VmHWM will tell you the memory highwater mark (max used) and VmRSS will give you the current memory usage.
:) cat /proc/self/status

jefflarkin / Automatically Sanitize fields for HTML display
Created November 18, 2009 22:15
# Sanitizing/Escaping HTML in the view is inefficient because it
# happens every time the view is rendered. This module forces
# text and string fields to be sanitized every time they are
# modified and saved to the database.
module Sanitizer
def sanitize_fields
columns = self.class.columns_hash
changes.each do |key,value|
if columns[key].type == :text
Sanitize.clean! value[1], Sanitize::Config::TEXTAREA

Created February 7, 2009 22:01
Sample code using JQuery Sortable lists. I've fixed my mistake, the code below should now work.

<style type="text/css">
#sortable ul {
list-style: none;
display: inline;
padding: 0;
margin-left: 0;
