variable = (condition) ? value-if-true : value-if-false;

which is equivalent to:

if (condition) {

variable = value-if-true;

} else {

variable = value-if-false;

}

I may consider using the “default” Mac VNC server, but I’ve heard it’s sluggish when connecting with a Windows client.

I’ll probably use Vine Server instead!

I’ll be using TightVNC for my windows VNC client

Unfortunately, I couldn’t locate the WordPress moderation controls, a guide by “Geekycoder” got me there. For future reference:

How to disable comment moderation in Wordpress

Login to wordpress account. Go to Option main tab, then select Discussion sub-tab.
Uncheck (no tick) the following two options:

• An administrator must always approve the comment
• Comment author must have a previously approved comment

1. Ensure that only the expected types are files (.jpg, .gif, .psd, .pdf to name a few) allowed.

How can this be achieved? Checking file extensions? Checking mime-encoding? imagecreatefromjpeg() (to validate jpgs)

2. Prevent malicious code from being uploaded and executed

Set default permissions to deny execute privileges on files. Deny extensions commonly associated with malicious code (exe, php, asp, js, no extension?, …?)

3. Prevent server disk space from completely completed exhausted in a short period of time (less than 24 hours)

“Captcha” prompt? Random question? IP logging? Minimum free space checks?

x. ?? What else? I would appreciate your input.

As a self-proclaimed nerd, I cringe everytime I hear someone complaining that their “internet is down”. In some sick, twisted way it brings me pleasure to talk about the internet being down, without feeling like I’m betraying my kind.

My condolences to those affected by this internet failure.

Since I needed to perform this check a number of times I made up a quick function to check if a directory was empty:

function dirIsEmpty($dir) {
   return (count(glob("$dir/*")) === 0) ? true : false;
}

What I failed to consider was that my webserver (which uses a linux OS) will always have parent (‘..’) and self (‘.’) references in each directory. I thought about using array_slice() to strip out the first 2 array elements, but then I would have run into issues with other operating systems.

Follow the jump to see the PHP function I ended up using.

This is the final version of the PHP function I use to check if a directory is empty:

function dirIsEmpty($dir) {
   $d = dir($dir);

   while (false !== ($entry = $d->read()))
      if ($entry != '.' && $entry != '..')
         return false;

   $d->close();
   return true;
}

Enjoy,

This is not just another party. This is a leadership training exercise. I like to find ways to combine fun, motivation, and education into a single mind-blowing, once-in-a-lifetime experience and I do this every January…. We’re going on a booze cruise on Lake Wallenpaupack. — Michael, The Office
