David Copeland:

Our goal should be to reduce these issues—we’ll never be truly rid of them. The first step is self-awareness. Ask yourself:

• “Do I know what I’m doing?”
• “Do I have a plan?”
• “Is this the simplest thing I could do?” (note: Simple ain’t easy)
• “What is the problem I’m trying to solve?”

Brandur Leach:

Versioning is always a compromise between improving developer experience and the additional burden of maintaining old versions. We strive to achieve the former while minimizing the cost of the latter, and have implemented a versioning system to help us with it. Let’s take a quick look at how it works.

Explicitly modeling changes between versions via a DSL.

About PumpkinDB:

PumpkinDB is essentially a database programming environment, largely inspired by core ideas behind MUMPS. Instead of M, it has a Forth-inspired stack-based language, PumpkinScript. Instead of hierarchical keys, it has a flat key namespace and doesn’t allow overriding values once they are set.

The core ideas behind PumpkinDB stem from the so called lazy event sourcing approach which is based on storing and indexing events while delaying domain binding for as long as possible. That said, the intention of this database is to be a building block for different kinds of event sourcing systems, ranging from the classic one (using it as an event store) all the way to the lazy one (using indices) and anywhere in between.

John Allspaw:

In my experience, when an architecture review brings attention to a problem and proposed solutions from multiple perspectives, decisions become less controversial. When a decision appears to be obvious to a broad group (“Question: should we (or should we not) take backups of critical databases? Decision: Yes.”) how a decision gets made almost disappears.

Max Kreminski:

Monads are a solution to a specific problem: the problem of repetitive code. If you write enough code in a functional programming language, you start to notice that you’re writing a lot of suspiciously similar code to solve a bunch of superficially different problems. Wouldn’t it be nice if you could just write this code once and then reuse it, instead of rewriting it slightly differently every time? I’m omitting a lot of detail here, but this is effectively what monads allow you to do.

Dave Copeland:

When a dangerous or difficult-to-undo operation must be performed, but it cannot be made idempotent without more context, use an Idempotency Key.
