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)

Methods of Signing with GPG on MacOS

Last updated June 23, 2022

There are now two ways to approach this:

Using gpg and generating keys
Using Kryptonite by krypt.co

This Gist explains how to do this using gpg in a step-by-step fashion. Kryptonite is actually wickedly easy to use-but you will still need to follow the instructions

Based on this blogpost.

To sign Git commits, you need a gpg key. GPG stands for GNU Privacy Guard and is the de facto implementation of the OpenPGP message format. PGP stands for ‘Pretty Good Privacy’ and is a standard to sign and encrypt messages.

Setting up

Install with Homebrew:

$ brew install gpg

	package main

	import (
	"fmt"
	"unsafe"
	)

	func main(){
	// integer for convert
	num := int64(1354321354812)

	package main

	import (

	fn find_subseq(s: &[u8]) -> u8 {
	let mut res: u8 = 1;
	let mut i = 0;
	while (i < s.len() - 1) && s[i] < 255 && (s[i] + 1 == s[i + 1]) {
	res += 1;
	i += 1;
	}
	return res;
