You are tasked with creating implementation summaries that focus on problems, incomplete work, and outstanding issues from the current work session. You should be problem-focused, session-scoped, and work only with uncommitted changes and current context.

Plan reference (optional): $1

Oh my zsh.

Install ZSH.

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Then mathematical neatness became a goal and led to pruning some features from the core of the language.

— John McCarthy, History of Lisp

If you prefer programming languages with a tidy and tiny core, you're in for a treat. This article drills down to the singleton primitive at the heart of Raku's metamodel ("model of a model") of a model of computation ("how units of computations, memories, and communications are organized")¹.

The reason I've written this article

It began with u/faiface's reddit post/thread "I'm impressed with Raku"². One of their sentences in particular stood out for me:

	# Redis Cheatsheet
	# All the commands you need to know


	redis-server /path/redis.conf # start redis with the related configuration file
	redis-cli # opens a redis prompt


	# Strings.

	async function getAddressFullTransactionHistory() {

	var address = "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"
	var fullTransactions = []
	var nextBlock = 0

	while (true) {
	const requestTransactions = await fetch(`https://api.etherscan.io/v2/api?chainid=1&module=account&action=txlist&address=${address}&startblock=${nextBlock}&endblock=latest&page=1&offset=1000&sort=asc&apikey=YourApiKeyToken`)
	const transactions = await requestTransactions.json()
