scolton99 / 2030_1824.js

Created March 10, 2021 21:25

Guide generation for Photoshop to mark the 18" x 24" bounds of an element at the center of a 20" x 30" document (works with anything of these aspect ratios).

	const [_1, _2, inx, iny] = process.argv;

	const sizediffh = (inx - ((24/30) * inx));
	const guidel = (1/2) * sizediffh;
	const guider = inx - (1/2) * sizediffh;

	const sizediffv = (iny - ((18/20) * iny));
	const guidet = (1/2) * sizediffv;
	const guideb = iny - (1/2) * sizediffv;

scolton99 / modulo.c

Created March 12, 2021 05:51

Demonstration of timing of C modulo vs. truncated division modulo.

	long mod();
	long mod_div();

	int main() {
	mod();
	mod_div();
	return 0;
	}

	long mod() {

scolton99 / shift_vs_add.c

Created March 16, 2021 06:04

Demonstration of time spent using shift operation vs an add operation.

	long add_a();
	long shift_a();

	int main() {
	add_a(5);
	shift_a(5);
	return 0;
	}

	long add_a(int a) {

scolton99 / Permuter.java

Created May 5, 2021 00:08

A terrible, horrible, no-good, very bad Java class to permute the elements of a list. Does not use memory well.

	package tech.scolton.util;

	import java.util.Collection;
	import java.util.List;
	import java.util.ArrayList;
	import java.util.Set;
	import java.util.HashSet;

	public class Permuter<T> {
	public List<List<T>> permute(Collection<T> rem) {

scolton99 / TechInterviewDriver.java

Created May 24, 2021 22:02

My solution to the Item Frequency problem.

	package tech.scolton.jordan;

	import java.util.*;

	public class TechInterviewDriver {
	public static void main(String[] args) {
	String[] input = new String[]{"apple", "apple", "orange"};
	Map<String, Integer> itemFreq = new HashMap<>();

	for (String s : input) {

scolton99 / opt.js

Created May 25, 2021 23:23

My solution to the word frequency problem in JavaScript.

	const input = ["apple", "apple", "orange"];

	const itemFreq = {};

	for (const s of input) {
	if (!(s in itemFreq))
	itemFreq[s] = 0;
	itemFreq[s]++;
	}

scolton99 / tree.js

Created June 28, 2021 19:18

A sketch of way to generate a decision tree on a website.

	const selector = "#root > li";
	const tree = {
	dom_el: null,
	text: 'root',
	children: []
	};

	const gen_tree = () => {
	const init = Array.from(document.querySelectorAll(selector));

scolton99 / exam_review.c

Created June 29, 2021 23:16

C file used to generate assembly for the first midterm review of NU COMP_SCI 213-0 (Spring 2021).

	long sus(long l, long m) {
	/* do nothing useful */
	if (!m)
	return 0;
	else
	return l + sus(l - 1, m - 1);
	}

	int amogus(unsigned char z) {
	long y = 0;

scolton99 / wait.js

Created September 16, 2021 20:38

Quick and dirty way to make a "sleep"-type function in JS (Browser or Node).

	const WAIT_TIME_MS = 3 * 1000;

	const wait = async ms => {
	return new Promise(resolve => {
	setTimeout(resolve, ms);
	});
	}

	const main = async () => {
	await wait(WAIT_TIME_MS);

scolton99 / untab.mjs

Created September 24, 2021 22:55

Convert tabs to spaces while keeping formatting. (Untested on non-4 tab sizes.)

	import fs from 'fs/promises';

	let TAB_SIZE = 4;

	const load_lines = async filename => {
	const data = await fs.readFile(filename, { encoding: 'utf-8' });

	await fs.writeFile(`${filename}.bak`, data);

	return data.split('\n');
