Change the name of the default branch created by `git init`

Suppose you want the default branch name created by git init (or tools that shell out to it, like cargo new) to be something other than master. In this example, I'll call it develop.

Add the following to your .gitconfig:

[init]
    templateDir = ~/.config/git/template/

Minecraft on Raspberry Pi cluster with metrics

Ever wanted to put your Rapsberry Pi cluster to great use? Our team is working remotely, so we started to play Minecraft. I decided I would host the Minecraft server on my Raspberry Pi cluster. This gist will guide you through the steps I took to get a k3s cluster up with k3sup and later installed Minecraft as well as metrics exporter and Prometheus Operator

Vim Script for Python Developers

This is a guide to Vim Script development for Python developers. Sample code for the various expressions, statements, functions and programming constructs is shown in both Python and Vim Script. This is not intended to be a tutorial for developing Vim scripts. It is assumed that the reader is familiar with Python programming.

For an introduction to Vim Script development, refer to usr_41.txt, eval.txt and Learn Vimscript the Hard Way

For a guide similar to this one for JavaScript developers, refer to Vim Script for the JavaScripter

This guide only describes the programming constructs that are present in both Python and Vim. The constructs that are unique to Vim (e.g. autocommands, [key-mapping](https://vimhelp.org/map.txt.html#key-m

Everything I Know About UI Routing

Definitions

Location - The location of the application. Usually just a URL, but the location can contain multiple pieces of information that can be used by an app
1. pathname - The "file/directory" portion of the URL, like invoices/123
2. search - The stuff after ? in a URL like /assignments?showGrades=1.
3. query - A parsed version of search, usually an object but not a standard browser feature.
4. hash - The # portion of the URL. This is not available to servers in request.url so its client only. By default it means which part of the page the user should be scrolled to, but developers use it for various things.
5. state - Object associated with a location. Think of it like a hidden URL query. It's state you want to keep with a specific location, but you don't want it to be visible in the URL.

An introduction to DynamoDB

DynamoDB is a powerful, fully managed, low latency, NoSQL database service provided by Amazon. DynamoDB allows you to pay for dedicated throughput, with predictable performance for "any level of request traffic". Scalability is handled for you, and data is replicated across multiple availability zones automatically. Amazon handles all of the pain points associated with managing a distributed datastore for you, including replication, load balancing, provisioning, and backups. All that is left is for you to take your data, and its access patterns, and make it work in the denormalized world of NoSQL.

Modeling your data

The single most important part of using DynamoDB begins before you ever put data into it: designing the table(s) and keys. Keys (Amazon calls them primary keys) can be composed of one attribute, called a hash key, or a compound key called the hash and range key. The key is used to uniquely identify an item in a table. The choice of the primary key is particularl

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.
