Auto-track a git branch

# Sets up auto-tracking of a remote branch with same base name.
# Can set up "git track" so it feels built-in:
# git config --global --add alias.track '!git-track'

branch=$(git branch 2>/dev/null | grep ^\*)

Big list of http static server one-liners

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

The relationship between state machines and event sourcing

A state machine is defined as follows:

  • Input - a set of inputs
  • Output - a set of outputs
  • State - a set of states
  • S0 ∈ S - an initial state
  • T : Input * State -> Output * State - a transition function

If you model your services (aggregates, projections, process managers, sagas, whatever) as state machines, one issue to address is management of State. There must be a mechanism to provide State to the state machine, and to persist resulting State for subsequent retrieval. One way to address this is by storing State is a key-value store. Another way is to use a SQL database. Yet another way is event sourcing. The benefit of even sourcing is that you never need to store State itself. Instead, you rely on the Output of a service to reconstitute state. In order to do that, the state machine transition function needs to be factored into two functions as follows:

[TIx 8] Weighted Random Sampling in Ruby

One of the many reasons I love working with Ruby is it has a rich vocabulary that allows you to accomplish your goals with a minimal amount of code. If there isn't a method that does exactly what you want, it's usually possible to build an elegant solution yourself.

Let's take the example of simulating the rolling of a die.

We can represent a die as an array of its faces.

die = [*?⚀..?⚅]
# => ["⚀", "⚁", "⚂", "⚃", "⚄", "⚅"]
