🔢 Dev Math: 100 Equations That Define Developer Reality

A collection of 100 tongue-in-cheek (yet oddly accurate) equations that model the beautiful chaos of software development.
This is your unofficial developer physics engine — balancing caffeine, meetings, deadlines, and dreams.

From productivity and debugging, to cognitive load, burnout, and system resilience — it's all math now.

💡 All equations are in LaTeX-style math, rendered in Markdown using $$...$$.

Install Updatable ReVanced Apps

This guide will teach you how to use Obtainium to install and update Revanced apps. The apps are prepatched and prebuilt on ReVanced Magisk Module. A new version of the included apps is created every time a new revanced patch releases. APKMirror is used to source the APKs, using the latest or recommeded version by Revanced.

Note

You must uninstall any previously installed ReVanced apps if it shows a conflict error when updating to the Obtainium version for the first time.

I'm using svelte 5 instead of svelte 4 here is an overview of the changes.

Overview

Svelte 5 introduces runes, a set of advanced primitives for controlling reactivity. The runes replace certain non-runes features and provide more explicit control over state and effects.

$state

Purpose: Declare reactive state.
Usage:

How to use this gist

You've got two main options:

new Worker().eat().sleep(2).work().sleep(2).eat().work()

Get this to print

eat
// wait for 2 seconds
work
// wait for 2 seconds

	//
	// ViewController.m
	// JBDetectTest
	//
	// Created by seo on 3/27/25.
	//

	#import "ViewController.h"
	#import <dlfcn.h>

	import type { PropsWithChildren, ReactElement, ReactNode } from 'react';
	import React, { Children, cloneElement, isValidElement } from 'react';

	import { render } from '@testing-library/react';

	function setFakeReactDispatcher<T>(action: () => T): T {
	/**
	* We use some internals from React to avoid a lot of warnings in our tests when faking
	* to render server components. If the structure of React changes, this function should still work,
	* but the tests will again print warnings.

	var active;
