Wondering if a certain outbound port on your Mac is open or closed? Here’s a way to determine outbound open ports on Mac OS using netcat via the command line in terminal. We’ll use using a free service from portquiz.net.
From the terminal, enter:
nc -v portquiz.net 443
where 443 is the port number you want to test.
Control-c will kill net cat after you get the info you want.
Easy-peasy. You can now determine outbound open ports on Mac OS.
You can easily install the intl international support extension to PHP 5.4 on Mac OS X 10.9 Mavericks Server. Here’s how:
You can easily install the mcrypt extension to PHP 5.4 on Mac OS X 10.9 Mavericks Server. Here’s how:
You can easily install the PHP SSH2 extension to PHP 5.4 on Mac OS X 10.9 Mavericks Server to support the CDN features of SocialEngine 4. Here’s how:
Dramatically speed speed up sites hosted using Mac OS X 10.9 Mavericks Server (like SocialEngine, Drupal, WordPress, or other PHP/MySQL web site) by adding APC and Memcache.
Here’s how to install APC and memcache on Mac OS X Mavericks server, which runs PHP 5.4:
Because Mavericks server uses PHP 5.4, any extensions you may have compiled for previous versions of Mac OS X (such as memcache, apc, mcrypt) need to be recompiled and reinstalled.
This post assumes you used MacPorts to compile and install the PHP extensions in question. Here’s how to accomplish the task:
I’m curious whether for-pay Facebook like sites like boostlikes really work. They have a free offer whereby one can gain 250 Facebook likes from “real” people. The catch? I have to post their URL to my site. Well, here we go. They claim I’ll notice results in 4-7 days. I’ll report back the results here. For the record, my page (which will be undisclosed) currently has 96 likes.
boostlikes even claims to be able to deliver likes from US-based Facebook users. Of course, that’s a premium price, but those are probably a) more valuable to US-based businesses; b) resonate better with US-based consumers; and c) cost more for boostlikes to acquire.

Last night I received notice from boostlikes that they kicked off my free campaign at 9:05 p.m. Within minutes I had 446 page likes, a gain of 350 likes. Most are from users with names of a Hispanic origin.
On the web, we’re often presented with a list of values that we need to display in a comma-separated manner.
For example, perhaps I would rather display a list of city names like Amsterdam London Paris Berlin as:
Amsterdam, London, Paris, and Berlin.
While we could tackle this with a variety of approaches including PHP or Javascript, we can also easily handle it with CSS.

I recently “obtained” some video files which had 5.1 surround sound encoded as AAC, but AppleTV does not play multichannel audio in AAC format.
While AppleTV can play back stereo or Dolby Pro Logic II in AAC format, it requires multichannel audio be encoded as AC3. None of these “acquired” MP4s have AC3 5.1 6-channel audio!
I could encode the file again, but that takes to much time. Is there a way I can just add or import AC3 multichannel audio to my existing video files?
The short answer is yes.
Apple prevents computers with USB drives from installing Windows from a USB flash drive on certain models. While it works flawlessly on my current gen MacBook Air, installing Windows 7 off a USB key doesn’t work on my iMac.
Luckily, the fix is easy…
