29 Jun 2010

“Hi.  I think our web site is down.” Nothing can ruin a day faster than those words.  It can send an afternoon into the can in three seconds flat. On the positive side, more often than not it’s really not a web site / web server problem.  On the negative side, that really doesn’t matter [...]

28 Jun 2010

I have been working on a post along the lines of “How to Troubleshoot Web Site Problems” but it started to get mired down in the details of DNS servers.  Thus, I decided to break the topic out into a separate posting to lay some groundwork first, THEN post the original tutorial.  So without further [...]

In: Mac|Opinion|Software|Tutorials & Explanations|Windows

22 May 2010

I recently received a call from a long-time client of mine asking for a little help in setting up a dual boot system so he could boot Windows on his iMac. Before delving into the “how to” process, I stopped and forced him to take a step back.  I asked “Why do you want to [...]

Easily Finding A Device’s UDID

In: iPhone|iPhone SDK|programming|Tutorials & Explanations

18 May 2010

When it comes to beta testing iPhone and iPad apps, let’s face it — Apple’s copy protection scheme (mobile provisioning profiles, etc.) is a real hassle.  From a business perspective, I very much understand why they do it, and why they try to keep a lid on things.  But that doesn’t change the fact that [...]

Compress ( aka Zip ) Problems in Mac OSX Leopard

In: iPad|iPhone|Software|Tutorials & Explanations|YouTube

13 May 2010

There’s a lot of confusion over this topic.  People keep wondering why there’s no Flash support on iPhones and iPads.  Considering that some 90% of the market is Windows-centric, I can understand the confusion.  I’ll try to explain here in non-technical, layman’s terms. Basically, it’s Apple’s position that Flash is buggy, crappy and a huge [...]

7 May 2010

After installing iWork ’09 on my iMac, I clicked the icon for Pages, watched it load up, then uncerimoniously crash.  Lovely.
