Dan-Q / _no_code_page_.php
Last active December 28, 2023 18:01
Hacky PHP to produce a "blank" web page which somehow has content when viewed in Firefox. Sample page at https://danq.me/wp-content/no-code-webpage/, explanation at https://danq.me/nocode
<?php
// half-hearted CSS minification
$css = preg_replace(
array('/\s*(\w)\s*{\s*/','/\s*(\S*:)(\s*)([^;]*)(\s|\n)*;(\n|\s)*/','/\n/','/\s*}\s*/'),
array('$1{ ','$1$3;',"",'} '),
file_get_contents('linked.css')
);
// embed as a data: uri
$base64css = rtrim(strtr(base64_encode($css), '+/', '-_'), '=');

This PHP script can be used to "proxy" content from third-party sites that block or modify their responses based on the Referer: header.
<?php
define('SECRET_PASSWORD', 'YOUR-SECRET-PASSWORD-GOES-HERE');

Dan-Q / get-twitter-avatar.js
Created June 2, 2021 08:33
Uses Puppeteer to get the current URL of any user's Twitter avatar by screen-scraping, for times when you're just too lazy to get some OAuth tokens and implement the Twitter API v2. Pass twitter usernames as command-line arguments.
/* Copyright (c) 2021 Dan Q; released under the MIT License. */
const Puppeteer = require('puppeteer');
getAvatar = async (twitterUsername) => {
const browser = await Puppeteer.launch({args: ['--no-sandbox', '--disable-setuid-sandbox']});
const page = await browser.newPage();
await page.goto(`https://twitter.com/${twitterUsername}`);
await page.waitForSelector('a[href$="/photo"] img[src]');
const url = await page.evaluate(()=>document.querySelector('a[href$="/photo"] img').src);

Runs in the background, makes an (inaudible?) sound every so often to keep your soundbar awake.

FREQUENCY = 37 # Hz; 37-32767 - what pitch sound?
DURATION = 1 # Ms - how long to play for?
