Weird HTTP Error 503

503 I’m working on an MVC Website. In development in Visual Studio, things are working perfectly. My app needs to run in IIS. Easy enough, right? Just set it up in IIS and you’re off and running.

Recently though, my IIS instance of the site stopped working. What?! I began to get the following error:

HTTP Error 503. The service is unavailable.

Wha wha wha?! I checked IIS and it’s running properly. What the heck? SQL Server is okay. The thing works perfectly in Visual Studio. ARG. Continue Reading

CustomPrincipal and Serialization

Recently, I’ve been working on a project that relies on a backend business object layer. The business object (BO) layer, requires authentication in order to be used. For most of the systems, this is okay, but my project is to be used by end users. We don’t need to authenticate the users… we need to authenticate the system.

This is easy enough using the CustomPrincipal object in Rocky Lhotka’s CSLA framework (which is also being used). We simply create the CustomPrincipal and add that to the ApplicationContext. Continue Reading

Use it or lose it

There’s a commonly known piece of information that pretty much everyone knows… use it or lose it. It applies to foreign languages, computer language, cooking techniques… all sorts of things.

Things like the code to unlock restrictions on an iPhone! Continue Reading

Burnin’ up the cellular data

I got a text message from AT&T this morning. It was a courtesy message to let me know that I was approaching my monthly data limit. I only signed up for the 200Mb plan so 65% of that means that I’ve used up 130Mb. How the heck did that happen?!

It turns out it’s not that hard to do… especially when you update your applications just before you leave the comfy confines of work and free wi-fi. I began the application update while connected to the wi-fi at work, but then left for home. The phone dutifully continued to update the applications over the cellular network. Ooops!

“Belts and Suspenders” or how to be really protected

Everyone knows they should be backing up their data, right? Just like flossing and rotating your tires though, sometimes it’s easy to let it slip for a while. But for those of you that *do* backup your data, are you doing it right?

First of all, there’s really no excuse for not backing up your data now-a-days. External hard drives are really affordable and dead simple. Backup software is built into most modern operating system to make it as invisible as possible. If you’re not backing up your data, you must have some sort of obsession with tempting fate.

Macs are awesome, but…

Here I am… happily working along when suddenly, the screen goes gray. My headphones cut out and I’m left in awful silence. On the gray screen, I get the following message…

“You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again.”

Windows Scheduled Task

We run lots of batch processes overnight. We do this to send emails, to generate reports, etc… We do all this via Windows Scheduled Tasks. It works great.

Recently, I needed to add a new scheduled task. I went through the process of adding the task but when I tried to run it, it failed. The error message I got was “Could not start task“

Release Mode error message

We’re approaching delivery of the baby! In the next few months, we’ll be releasing our product. This is great news as it’s been a long time coming. As is the norm, we’ve been developing our product in Debug mode. While in Debug mode, Visual Studio will generate extra files to allow stepping through the code. This is a great thing for creating the initial code, but it’s not necessary for code that’s deployed to the world at large.

When I switched Visual Studio over from Debug mode to Release mode, I got a weird error. Continue Reading

Unknown class “class name” in Interface Builder file.

Wow… just… wow. This took a long time to figure out. I was trying to create and use a custom UIButton in an iOS project. Everytime I tried it, the app would open and immediately close. Typical crash behavior.

As is the norm, I opened the console. This is my first step in trying to figure out what the heck is going on.

Keybindings on the Mac

As you’ve probably gathered, I (proudly) consider myself a Mac guy. I have spent enough money on Apple products to allow El Jobso to get an extra cup of coffee every day for the rest of his life. I do a lot of work on my Macs. But I’ve been a Windows developer since… well, nearly forever.
