• Code Reuse is (Damn) Hard

  - by James Michael Hare

  Being a development team lead, the task of interviewing new candidates was part of my job.  Like any typical interview, we started with some easy questions to get them warmed up and help calm their nerves before hitting the hard stuff.

• ANTS Memory Profiler 7.0

  - by James Michael Hare

  I had always been a fan of ANTS products (Reflector is absolutely invaluable, and their performance profiler is great as well – very easy to use!), so I was curious to see what the ANTS Memory Profiler could show me.

• Is there any reason to allow Yahoo! Slurp to crawl my site?

  - by James Skemp

  I thought a year or more ago Yahoo! would be using another search engine for results, and no longer using their own Slurp bot. However, a couple of the sites I manage Yahoo!

• Handling Errors In PHP When Using MVC

  - by James Jeffery

  I've been using Codeigniter a lot recently, but one thing that gets on my nerves is handling errors and displaying them to the user.

So, when should you use each of these…
