Nowadays, Agile Manifesto is a Bible of numerous software teams. It contains 12 principles which show us how software development should be organized. These principles were invented in 2001.

Consequently, here is a summary of what's going on and my interpretation of each principle.

DTO, as far as I understand it, is a cornerstone of the ORM design pattern, which I simply "adore." But let's skip to the point: DTO is just a shame, and the man who invented it is just wrong. There is no excuse for what he has done.

I think it's too obvious to say that a singleton is an anti-pattern as there are tons of articles about that (singleton being an anti-pattern). However, more often than not, the question is how to define global things without a singleton; and the answer to that is not obvious for many of us. There are several examples: a database connection pool, a repository, a configuration map, etc. They all naturally seem to be "global"; but what do we do with them?

There are basically two ways to validate a situation in Java and complain when something unexpected happens. It's either an exception or an assertion. Technically, they are almost the same, but there are some small differences. I believe that exceptions are the right way to go in all situations and assertions should never be used. Here's why.

I was talking yesterday with a few friends who were software conference organizers. They were asking about my opinion of the conferences I've recently attended.

A project manager is very often confused with a leader. However, they are two very different things. A project manager is the one who predicts the future, while a leader is the one who builds it.

"Convertible Notes" is what you most likely will hear the first time you get money for your first startup. They will give you cash asking to give them the convertible notes (or SAFE, which is very similar). Convertible notes are just a few pages of paper with two signatures at the bottom. Not too much to worry about. It's basically a contract between your startup and an investor. Let's see what exactly it says and what you, as a founder, should pay attention to.
