Rails to React.

It’s not that new technology should never be introduced, but it should be done with rational defensiveness, and with a critical eye in how it’ll fit into an evolving (and hopefully ever-improving) architecture.

It suggests improving increasing productive output by continually improving the efficiency of a system even while keeping input the same. I project this onto technology to mean building a stack that scales to more users and more activity while the people and infrastructure supporting it stay fixed.

Programming calendar time is hard.

I always enjoy the behind the scenes stories of comedians.

A look into some of the inspiration and decisions in the design of Elixir.

Jujitsu and meditations on narrative and consciousness.

A visual demo.

Ben Smith:

Building applications following domain-driven design and using CQRS feels really natural with the Elixir – and Erlang – actor model. Aggregate roots fit well within Elixir processes, which are driven by immutable messages through their own message mailboxes, allowing them to run concurrently and in isolation.

I too think that Elixir is a good fit for CQRS/ES applications.

The post provides a thorough walkthrough that builds an event sourced/CQRS Elixir application using Phoenix, Commanded, and Eventstore. The Commanded and Eventstore libraries look to have implemented most of the features I’m looking for.

Some amazing work.

Killer drumming.

Greg Young:

We will talk about what seems to be the most complex areas of event sourcing for most developers especially those first getting into it. Versioning.

Remapping the event stream is an approach we’ve used. I like the idea of emitting stop and stopped events to the store to support zero downtime migrations while remapping the stream.

Dan North:

Over the last year or two I have been exploring OKRs—Objectives and Key Results—with several organisations, from a few hundred people in size to a couple of thousand. Some are well over a year in, some are just starting out. There doesn’t seem to be much out there in terms of experience reports or hands-on advice so I have tried to capture the advice I wish I’d had when I started out.

A different future.
