Are You in a New Project?

Hi, You are new to a project. Maybe you have just changed jobs. Or an opportunity has arisen internally - whether you wanted it or not. Your first day. You really don’t know anything about the project. So almost nothing. You know what it’s about. You may have even tried the product yourself. But you don’t know what the architecture looks like. You don’t know how many services the product operates. What they run on. How they’re interconnected. Where the data is persisted. Is it relational at all?

The First Ideal: Locality and Simplicity

Hi, I once developed a backend with just two engineers. It was the backend for Sunrise Village . I joined the team already in the pre-production stage, together with my then colleague. For over three years, we were the backend team. The other teams were larger. We had up to 8 frontend developers, a similar number of artists, two game designers, product owners, product managers, and 2 test automators. Even the fact that there were only two of us was actually too many. We kept it that way for risk minimization - in case one of us was unavailable.

"I think Loom is going to kill reactive programming." ~Brian Goetz

Hi, “I think Loom is going to kill reactive programming.” This statement comes from Brian Goetz . Do you know who he is? Brian has been the Java Language Architect at Oracle for 13 years. He is the author of “Java Concurrency in Practice” - a standard work for every Java developer . He was also the one who brought JSR-335 - Lambda Expressions - into the language. What Brian says has substance. You’ll hardly find anyone else in the world who can provide a better outlook on the future of Java and its ecosystem.

Surprising Documentation

Hi, Class comments, architecture documentation, method comments, API documentation, inline comments, feature documentation, wireframes, entity-relationship diagrams, use-case diagrams, process documentation, end-user documentation… There are so many things one can document. But what do I really need? Documentation doesn’t write itself. Someone has to take the time. And for it to truly add value, it needs to be well-written, as complete as possible and focused. Not everyone can do that. In large corporations - with thousands of employees - a lot is documented. There are software architects who have the time and education to write good documentation. There are so many developers that enough time is allocated to document the code. And technical writers produce the highest quality end-user documentation.

Double-Entry Bookkeeping

Hi, An error in accounting can be costly. Especially in large companies, where there are many transactions, it is easy to overlook one. And when that happens, I might not even notice it. Perhaps the company is doing much better than the books indicate? Or maybe it’s actually unprofitable? Merchants in the 13th century recognized the problem. A system had to be found that would make errors less likely. They invented double-entry bookkeeping.
