Very often I used to find that my Linux box(s), Fedora & Ubuntu both started reserving more RAM over a period of time since its boot. And the actual RAM left free was less.

I knew it was holding some caches for itself so that it could find the programs loading “quickly” and something like that.

The most common way to free up RAM is Rebooting! But I wanted to avoid it, so did a little “Googling” and I came up with an interesting solution – Tell linux to flush all the caches.

# Flush file system buffers by executing
sync;

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

def parse_diff(changes)
  # [["~", "name", "original name", "updated name"]] => {:name => ['original_name', 'updated_name', 'Modify']}
  parsed_diff = {}
  changes.each do |change|
    unless change[1].match(/updated_at/) || change[1].match(/.id/) || change[1].match(/.created_at/)
      if change[1].match(/line_items/) || change[1].match(/site_lists/) || change[1].match(/zip_code_lists/)
        change[1].gsub!(/\d+/, Random.rand(1000).to_s)
      end
      type = if change[0] == "+"
        "Add"

Responsive Mail UI

Credit for design goes to Vivek Venkatraman: http://dribbble.com/shots/1455744-Email-Concept/

Check it out in full view to see it's responsiveness. It's responsive until pretty darn small but i haven't actually tested it on mobile devices. Tested in IE9+, latest Chrome and Firefox.

I've noticed the message (slide-in section) is some times visible on page load. If that's the case just reload the page, that's a browser bug.

Forked from Nicklas Sandell's Pen Responsive Mail UI.
