Lets talk about software development. Recently I have worked to get a team I am part of using a new development methodology called BDD, or behavior driven development. If you develop software at all, and have not been living under a rock for the past 10 years you maybe wonder if BDD is anything like TDD. The answer is [...]

One of the major disadvantages to using a popular CMS like Joomla or WordPress is that the popularity of the platform means that it is also a popular target for black hat hackers. Until recently I was using Joomla to manage all the content on my website during this 5+ year time period my site [...]

Bruce Schneier Quotes
A couple good quotes from a great article from Bruce Schneier. “Security is a mindset, and looking for vulnerabilities nurtures that mindset. Deny practitioners this vital learning tool, and security suffers accordingly.” … “Anyone can design a security system that he cannot break. So when someone announces, “Here’s my security system, and I can’t break [...]

Ostrich Based Security
Security, it is one of those hot button issues. Lots of companies like to pretend they are security conscious.

NotNull sounded good, but was not
A couple weeks back I published Jmaxxz.Deet, a software library which brought reference types to the C# language which were guaranteed never to be null. While I maintain that null references are an indication of poor design and should be avoided at all cost, I am forced to admit that Jmaxxz.Deet is not the answer. Over the course of [...]
