Defensive programming good or evil?

Based on a recent discussion I had with a friend of mine, I am curious to know what other people think.

The discussion revolves around the use of defensive programming techniques, as implicitly discussed in my recent article. I am going to discuss two issues.

New Company

A few days ago I decided it is time to start another small company called Photudio. I have been interested in photography since I was a little boy running around with my Vivitar 35mm point and shoot film camera.

The web site contains some photos from each portfolio I like to take pictures for. Since I am interested in many different subjects, I have created distinct portfolios. Commercially I prefer doing Weddings, Model Portfolios, Still life and family portraits.

I hope this will become a viable company since I love photographing beauty...

%$#%$#% Spammers!!!!

Some freak decided tonight that it is a good idea to submit about 40 SPAM comments on my blog, distributed evenly across the blog entries... I had to delete them all one by one over an HSCSD (28.8kbps) connection.

The only temporary remedy I could find is to turn comments off. If you know of any way to work around this, please email me!

The burglar alarm installation went well bar the misconception regarding the time it took to have installed it. After a week of struggling I got it in and fully working - finally! There were 22 cables I had to pull through the roof, which was no easy job...

So you are interested in the performance of the system? I love the Optex sensors, they work brilliantly. So far I only had two false alarms - one from an unknown source in the dining room, and one from the garage where my cat was locked in.
