Kotlin Flow Cheat Sheet

Flow Types

Flow Type	Purpose	Key Features	Use Case
`flow {}`	Creates a cold flow that emits values lazily.	Emits values only when collected. Supports suspending functions.	Creating custom flows to emit data on demand.
`flowOf()`	Creates a flow from a fixed set of values.	Emits provided values sequentially. Cold by nature.	Emit predefined values (e.g., configuration settings).
`asFlow()`	Converts collections, sequences, arrays, or ranges to flows.	Supports many standard types. Cold by nature.	Convert lists or arrays into flows for processing.
`c

FFmpeg Cheatsheet

Common FFmpeg Options

Option	Description	Example
`-i`	Input file	`ffmpeg -i input.mp4`
`-vf`	Video filters (apply effects to video)	`ffmpeg -i input.mp4 -vf "scale=1280:720" output.mp4`
`-c:v`	Video codec (specify video compression method)	`ffmpeg -i input.mp4 -c:v libx264 output.mp4`
`-c:a`	Audio codec (specify audio compression method)	`ffmpeg -i input.mp4 -c:a aac output.mp4`

🏫📄 Worksheet Generators

For inspiration and ideas for my Math Homework Generator, I figured that I should start a list of pages I should look through eventually to learn about what's out there and what might be lacking. MHG is often found in other lists which is how I found these links.

How to Setup Verified Commits

Quick guide on how to setup git signing. Information is aggregated from following sources:

	#!/bin/sh

	print_usage() {
	echo "usage: compress_video <input_file>"
	echo "supported formats: mp4, webm, mkv, mov, avi, flv"
	}

	get_extension() {
	f="${1##*/}"
	case "$f" in

	import sys
	import anthropic
	from dotenv import load_dotenv
	load_dotenv()

	client = anthropic.Anthropic()

	prompt_template = """
	Please review and edit the following text to ensure it is grammatically correct, clear, and concise. Aim to maintain a casual tone without being overly informal.

	if [[ "$#" -ne 3 \|\| "${1}" == '-h' \|\| "${1}" == '--help' ]]; then
	cat >&2 <<"EOF"

	gcr-cleaner.sh will cleans up the gcr tags or untaged images pushed in a repository (image name with the specific tag)
	and except the given number most recent images.
