Greg Young: 8 Lines of Code

Greg Young gave a good talk titled 8 Lines of Code, discussing simplicity, dependencies, and magic.

Magic is always something I try and identify and stay away from in my own code, however I really failed to realize how much magic goes on in some of the libraries/frameworks that I often use.  Entity Framework and nHibernate come to mind.  You really should understand the magic happening in these libraries to use them.  Which is very problematic.

If you take the dependency ownership seriously, then a lot of folks developing the front-end of a “modern” web applications are in a world of hurt.  RequireJS, Knockout.js, jQuery, Bootstrap, etc, etc, etc…

Idiotic Interview Questions

Interviews questions always seem to be a topic that comes up frequently at a developer peer group I attend and while at work.  In a recent .NET Rocks! podcast, they touched on this topic and brought up the Fizz Buzz Test.  We have all been in interviews where we are given some ridiculous programming question, that is “intended” to show the interviewer your problem solving skills.  Or maybe (I think likely) they ask these questions because they are the stock questions, and everyone asks them.  It’s like asking someone for their strengths and weaknesses.  Do you really think people aren’t telling you what you want to hear.  These stock questions have stock answers.

Back to the ridiculous programming questions.   If someone asked me today in an interview some asinine array sorting question, or better yet a problem that you rarely encounter in the real world, I think my answer would be: Google.

Most of the problems that I encounter in the real world have been already dealt with.  I do not need to come up with my own solution.  I’m not arrogant enough to think that my solution is the best.  Using available resources (ie, Google) to to find the best solution to a problem seems like a better answer.  After all, wasn’t the point of the question to see your problem solving skills?  Why not ask questions related to Patterns, Practices, and Principles?  If the interviewee can discuss SOLID principles, doesn’t the Fizz Buzz Test seem idiotic to ask?
