Framework Load Testing: Performance is One Aspect ...

Webapper just released an interesting summary of load testing the CFPetMarket in its various incarnations. (Go to cfpetmarket.com to download the different versions of the application.)

I don't think the results are all that surprising, so I won't belabor them here. What I do want to offer is a bit of my perspective on the issue of frameworks, CFCs, and performance in general.

First and foremost, remember that performance is one aspect of software development. Clearly our applications must have acceptable performance in order to be successful. What I'm afraid of is that people will look at these numbers and gravitate towards a "Fusebox is fast, Mach-II is slow" line of thinking. Mach-II is slower than Fusebox, but as the Webapper folks and Simon Horwith both point out, this is to be expected based on the CFC-heavy nature of Mach-II applications.

Note that I said Mach-II is slower than Fusebox, but that doesn't at all mean that Mach-II is slow. Performance is one aspect of software development, and if that was the only aspect of it, then we could all spend our time writing ultra-fast code that is unmanageable and perhaps even unreadable. We also have to maintain what we write, and this is where frameworks in general, and specifically Mach-II in my opinion, excel. That's not to say Fusebox isn't a great framework choice as well, I just think that for CFC-based development Mach-II is preferable. (I know, I'll probably get some contrary opinions on that, which is fine.)

The point I'm trying to make is that raw performance numbers aren't everything, and speed is relative. Think "fast enough," not just "fast," and always be mindful of the maintainability of your applications which in my opinion is FAR more important than raw speed. Maintenance is where all the money is spent, so as long as the application performs well (which Mach-II applications most certainly do) but is also easily maintainable, it will be a success over the long haul, not just in isolated load testing scenarios.

Installing and Configuring NextPVR as a Replacement for Windows Media Center

If you follow me on Google+ you'll know I had a recent rant about Windows Media Center, which after running fine for about a year suddenly decided as of January 29 it was done downloading the program guide and by extension was therefore done recording any TV shows.

I'll spare you more ranting and simply say that none of the suggestions I got (which I appreciate!) worked, and rather than spending more time figuring out why, I decided to try something different.

NextPVR is an awesome free (as in beer, not as in freedom unfortunately ...) PVR application for Windows that with a little bit of tweaking handily replaced Windows Media Center. It can even download guide data, which is apparently something WMC no longer feels like doing.

Background I wound up going down this road in a rather circuitous way. My initial goal for the weekend project was to get Raspbmc running on one of my Raspberry Pis. The latest version of XBMC has PVR functionality so I was anxious to try that out as a …

Running a Django Application on Windows Server 2012 with IIS

This is a first for me since under normal circumstances we run all our Django applications on Linux with Nginx, but we're in the process of developing an application for another department and due to the requirements around this project, we'll be handing the code off to them to deploy. They don't have any experience with Linux or web servers other than IIS, so I recently took up the challenge of figuring out how to run Django applications on Windows Server 2012 with IIS.

Based on the dated or complete lack of information around this I'm assuming it's not something that's very common in the wild, so I thought I'd share what I came up with in case others need to do this.

Setting Up Django On a Raspberry Pi

This past weekend I finally got a chance to set up one of my two Raspberry Pis to use as a Django server so I thought I'd share the steps I went through both to save someone else attempting to do this some time as well as get any feedback in case there are different/better ways to do any of this.

I'm running this from my house (URL forthcoming once I get the real Django app finalized and put on the Raspberry Pi) using dyndns.org. I don't cover that aspect of things in this post but I'm happy to write that up as well if people are interested.
