lelandbatey / sqlite_index_rules_demo.py

Created September 29, 2025 21:00

A demonstration of the concepts ruling SQLite indexs (and many DB indeces implementations)

	# in response to this conversation: https://news.ycombinator.com/item?id=45417191
	from pprint import pprint
	# group_by here is ultimately used to create a tree structure (nested dictionaries) of the form
	# keys[0] -> keys[1] -> ... -> keys[n] -> getid(object). We use it here to construct a tree data
	# structure that's conceptually equal to a database index (not exactly the same, but shows the same
	# properties we care about).
	def group_by(objects, keys, getid=None):
	if getid is None:
	getid = lambda x: x['id']
	result = {}

lelandbatey / scold_git_checkout.bash

Created January 9, 2025 22:27

Scold for using Git Checkout

	# Paste this snippet into your .bashrc to help you learn `git switch`.
	#
	# Turn on the extdebug mode so that our `scold_git_checkout` can prevent
	# us from running git-checkout by exiting 1; forcing us to re-learn our
	# muscle memory.
	# If we really need to use git checkout for something, we can do that
	# by using the full path to the git executable e.g.:
	# /usr/bin/git checkout # isn't caught by our scolding
	shopt -s extdebug

Prints a detailed view of all arguments. When you're confused about args, substitute in `cmdinfo` for a hex dump of every arg.

	// Compile with:
	// gcc ./cmdinfo.c -lm -o cmdinfo

	#include <stdio.h> /* printf(), fprintf() */
	#include <string.h> /* strcmp() */
	#include <math.h> /* log10(), ceil() */

	// fwd decl to cease warnings
