Florian Eberhart - LinkedIn spam

The following is a message I shared on LinkedIn, posted 2024-02-04. I figured it might be handy to have a public facing page. That way, one does not need to be on LinkedIn to read it. If anyone wants to pick this up as part of a larger content moderation story, you have my permission.

🔗 Original post on LinkedIn

I want to give a shout-out to Florian Eberhart for being especially popular amongst LinkedIn spam bots. I have received several identical messages encouraging me to register for his upcoming event. At the time of this writing, it looks like 14 people are planning to attend.

For work, I made an example of how to cache a fetch promise.

This is different than awaiting a promise and saving the result. Subsequent calls will use the same promise.

It outputs alternating logs:

Image object.
String "bad dog".

How to use

To use this Node script:

Save the contents of the script in a file named har-domain-parser.cjs.
Place your trace.har file in the same directory as the script file.
Then run the script using the command line.

	// Define function.
	function waitForDeps(obj, list) {
	// Expose promise.
	return new Promise((resolve) => {
	// Start polling.
	const interval = setInterval(() => {
	// Get missing.
	const listMissing = list.filter(key => !obj[key]);

	// All clear?

	/**
	* Gets the median for a list of numbers.
	*
	* @param {number[]} [listSorted=[]]
	* @returns {number}
	*/
	const getMedian = (listSorted = []) => {
	// Get count.
	const listCount = listSorted.length;

	// ======
	// Types.
	// ======

	type DeepReadonly<T> = {
	readonly [K in keyof T]: T[K] extends Record<PropertyKey, unknown> ? DeepReadonly<T[K]> : T[K];
	};

	// ===========================
	// Helper: deep freeze object.

	/*

	NOTE:

	This works with LinkedIn's current markup, as of 2024-02-23.

	Run it via the dev tools console, while on your "following" page.

	// Helper function to determine error message.
	const getErrorMessage = (error: Error \| ErrorEvent \| PromiseRejectionEvent): string => {
	// Set later.
	let message = '';

	// Message string?
	if (typeof (error as Error)?.message === 'string') {
	message = (error as Error)?.message;

	// Reason string?

	// ============
	// Helper: log.
	// ============

	const log = (error) => {
	console.log(error?.message \|\| error);
	}

	// ===============
	// Promise reject.

	require('@testing-library/jest-dom');

	// Override.
	Object.defineProperty(window, 'requestAnimationFrame', {
	writable: true,
	value: (f) => {
	if (typeof f === 'function') {
	f();
	}
