How to Clear all Whitespace in Vim

Andrew Brown — Sat, 21 May 2011 23:59:23 +0000

All you need to do is type:

:%s/\s\+$//

But what I think you really want to do is add this to your .vimrc file.

map cw :%s/\s\+$//

Then you can just type

\cw

and it will clear all whitespace in your current file.

Always Have this Year in Your WordPress Footer

Andrew Brown — Tue, 01 Mar 2011 20:24:48 +0000

The year has changed, but your footer hasn’t. One minor adjustment and you’ll never have to worry about that year being out of date again.

This is what we’re going to add

('Y') ?>

Your footer code will look a bit different from mine, but just open footer.php in your wordpress template, and replace the year with the line of code above, you’ll never have to update your footer again.

        <div class="footer">
          <p>
            ('Y') ?> © Monsterbox Productions
          </p>
        </div>        
      </div>
    </div>
  </body>

How to Join three table together in MySQL. Left Join Maddness!!!

Andrew Brown — Tue, 01 Mar 2011 19:22:26 +0000

The Problem

I’m building a web-app with groups. There are a bunch of links in the group, and you can star, comment thumb them up. Then there is a page that shows who has starred, commented and thumbed things. Basically like digg or reddit.

So that means I need to join three tables together:

group_shared_links
shared_links
links

It may sound dumb but I didn’t learn how to use join’s recently. Never had to, so if your in the same boat that I was in, I hope I can save you time learning how to do this with my example.

When you have callbacks inside callbacks inside callbacks, it what we call in NodeJS boomerang code. Because it looks like a boomerang. Your javascript will become un-managable so we need a better way.

You can use flow-js, and step, but I’m going to use funk.
