MicroObjects is a fantastic way to write OO code. There's very few pain points that I've encountered. The teams using MicroObjects deploy confidently and have near zero bugs. New functionality and features are quick and easy to implement. The practice is vastly different than how most people write code. Most…
We don't have to agree on everything to learn and grow from each other. This is exemplified for me with the Elegant Objects by Yegor Bugayenko. Elegant Objects being a book read about 6 months after an OOBootCamp from Fred George crystallized a few remaining pieces that the boot camp…
I was at a the FlatIron Seattle open house where I met many great people. I had a great time talking with people about testing and Test Driven Development. It's something not as heavily emphasized as I think it should be in the education and training of individuals in our…
I'm going to start this with saying that Clean Code helped me a lot early in my career. It also hindered me a lot. Clean Code places so much emphasis on things so trivial... I was misinformed about what is actually important to writing software. This used to be my…
There's a few ways I've talked about this historically. One of the biggest that is probably well recognized in the industry No Nulls Do not let nulls into your code. Clean Code touches the idea All it takes is one missing null check to send an applicaation spinning out of…
Low coupling can mean a few flavors of things depending on your context. My general definition of Low Coupling is "Not knowing what it is, just what it does". This allows us to interact with objects without knowing the underlying implementation, and unable to make any assumptiosn about…
No Getters We've covered why we don't use getters. This reason is the fundamental principle driving all of Object Oriented Programming. Encapsulate Behavior. Encapsulating behavior allows changes to that behavior with a guarantee it is changed across the system. We need to encapsulate the behavior. The switch statement and the…
A question on twitter has moved forward doing an example of serialization and deserialization. This is gonna be a pretty quick example and blog post as this is being done so that I can provide a code sample as my answer to the asker! I'm going to use JSON as…
At a GREAT [Seattle Software Craftsmanshi meetup where David Bernstein gave a talk, there was a question at the end that really piqued my interest. The question was, paraphrased: How can we get tests for something using the HttpClient? This is a C# specific question - and ... well.... I happen…
I see High Cohesion as a key component of getting single responsibility into code. Hopefully it's clear from my blogging that there's far more to it than just one thing, but a class that is does not have High Cohesion cannot have a single responsibility. Why is that? A class…
