Never produce to an unknown pathway, in software too? [Toyota principle]
In Toyota manufacturing lines they always know what path a part have traveled. Just so they can be sure they can fix it of something goes wrong. Is this applicable in software too?

Service Layers and Repositories
I've been using MVC frameworks for a short while now and I really like how the concerns are separated out. I've got into a bad habit of letting the controllers do quite a bit of work. So I'm really looking for some advice. When I first started using MVC I quite often had the controller doing manipulation on the models after database w...
LINQ To Entities and Lazy Loading
In a controversial blog post today, Hackification pontificates on what appears to be a bug in the new LINQ To Entities framework: Suppose I search for a customer: var alice = data.Customers.First( c => c.Name == "Alice" ); Fine, that works nicely.

Objectively Good OO Design Principles

Hello, I've just recently started learning HTML/CSS and I've been trying to teach myself sound web programming practices.
