A composable pattern for pure state machines with effects (draft v3)

A composable pattern for pure state machines with effects

State machines are everywhere in interactive systems, but they're rarely defined clearly and explicitly. Given some big blob of code including implicit state machines, which transitions are possible and under what conditions? What effects take place on what transitions?

There are existing design patterns for state machines, but all the patterns I've seen complect side effects with the structure of the state machine itself. Instances of these patterns are difficult to test without mocking, and they end up with more dependencies. Worse, the classic patterns compose poorly: hierarchical state machines are typically not straightforward extensions. The functional programming world has solutions, but they don't transpose neatly enough to be broadly usable in mainstream languages.

Here I present a composable pattern for pure state machiness with effects,

Setting up Spacemacs on Windows 10

Install Emacs First

Download emacs-w64 and extract somewhere, e.g. a tools or apps folder like C:\Users\<user>\tools\emacs.

Select Emacs' Home

Emacs and many other applications store its configuration in the user's "home" folder. Translated directly from the Unix world, that is %UserProfile% (C:\Users\<user>), but Windows prefers %AppData% instead (C:\Users\<user>\AppData\Roaming).

For simplicity's sake, override this by specifying the HOME environment variable explicitly. Emacs and some other applications (e.g. MinGW) lets this override the default.

NodeJS script to remove 1000 DNS records added by Cloudflare when used * (wildcard) A record
// Now if you adding a domain with wildcard A record, Cloudflare uses strange scan, which added a 1000 trash domains (like 1-100, some english words like "ai", "air", "android").
// There's no way to bulk delete it, you can delete it only using their API.
// So I write a script that can help you with this problem.

How to combine two git repositories.

Combining two git repositories

Use case: You have repository A with remote location rA, and repository B (which may or may not have remote location rB). You want to do one of two things:

  • preserve all commits of both repositories, but replace everything from A with the contents of B, and use rA as your remote location
  • actually combine the two repositories, as if they are two branches that you want to merge, using rA as the remote location

NB: Check out git subtree/git submodule and this Stack Overflow question before going through the steps below. This gist is just a record of how I solved this problem on my own one day.

Before starting, make sure your local and remote repositories are up-to-date with all changes you need. The following steps use the general idea of changing the remote origin and renaming the local master branch of one of the repos in order to combine the two master branches.
