How to sync Obsidian with Git on Android

Limitations

• If Termux is closed in the background by Android, the cron service will stop updating your repository and you must open Termux again. Refer to instructions for your device model to disable the killing of certain background applications.
• This may negatively affect your devices battery life. I'm not entirely sure yet.

Setup

• Install Termux – Apps on Google Play

• Local prototyping with hot-reloading and step through debugging: npm run watch
• Bundle, minify and valid structure for SAM package/deploy: npm run build

TL;DR

• Webpack is instructed to dynamically look up for index.ts within src folder -- (src/function1/index.ts, src/function2/index.ts)
• Webpack builds a bundle per function to build/function1/index.js, build/function2/index.js...
• SAM CodeUri is set to the build folder build/function1

DevOps started out as "Agile Systems Administration". In 2008, at the Agile Conference in Toronto, Andrew Shafer posted an offer to moderate an ad hoc "Birds of a Feather" meeting to discuss the topic of "Agile Infrastructure". Only one person showed up to discuss the topic: Patrick Debois. Their discussions and sharing of ideas with others advanced the concept of "agile systems administration". Debois and Shafer formed an Agile Systems Administrator group on Google, with limited success. Patrick Debois did a presentation called "Infrastructure and Operations" addressing

defmodule Boydm.Utilities.Map do

  #============================================================================
  # similar to List.meyers_difference, the below code compares two maps
  # and generates a list of actions that can be applied to the first map
  # to transform it into the second map.

  #--------------------------------------------------------
  def difference(map_1, map_2) when is_map(map_1) and is_map(map_2) do
    # remove any keys from map_1 that are simply not present (at all) in map_2

Motivation

In Redux, reducer composition with combineReducers offers a powerful way to handle complex update logic of an application. A reducer can encapsulate all the ways a part of the state is mutated because it can react to multiple types of actions.

But in some cases there is also a need for another type of factoring: often the update logic is simple (for example setting a single value), and the there are many places in the state shape where the update logic is the same.

Type Safe JSON Decoding in Elm

The power of a Static Typed language can seem magical at first. But the goal here is to take a tiny peak behind that curtain.

Elm's implementation of JSON parsing is type safe and how it achieves that can seem like a mystery. Even though I got the code to work, it took me a while to fully understand how it works.

I'm writing it down here for 2 reasons. To help others gain a greater understanding of Types and so I don't forget what I learned.

Word of Caution

Atom Clojure Setup

This describes how I setup Atom for an ideal Clojure development workflow. This fixes indentation on newlines, handles parentheses, etc. The keybinding settings for enter (in keymap.cson) are important to get proper newlines with indentation at the right level. There are other helpers in init.coffee and keymap.cson that are useful for cutting, copying, pasting, deleting, and indenting Lisp expressions.

The Atom documentation is excellent. It's highly worth reading the flight manual.
