hi, i'm daniel. i'm a 15-year-old with some programming experience and i do a little bug hunting in my free time. here's the insane story of how I found a single bug that affected over half of all Fortune 500 companies:

say hello to zendesk

If you've spent some time online, you’ve probably come across Zendesk.

Zendesk is a customer service tool used by some of the world’s top companies. It’s easy to set up: you link it to your company’s support email (like [email protected]), and Zendesk starts managing incoming emails and creating tickets. You can handle these tickets yourself or have a support team do it for you. Zendesk is a billion-dollar company, trusted by big names like Cloudflare.

Personally, I’ve always found it surprising that these massive companies, worth billions, rely on third-party tools like Zendesk instead of building their own in-house ticketing systems.

The introduction to Reactive Programming you've been missing

Here's the history, hope it helps.

I wrote the original version of the npm registry in a day or two on top of CouchDB. I built it quickly and didn't think much about scale.

Isaacs continued to improve and maintain that code. At one point he even wrote up an open standard for generic js package registries for CommonJS but they didn't seem to care (they were too busy arguing about promises).

At the time I wrote the initial code I was employed at CouchOne and we had a small CouchDB hosting platform operated by Jason Smith which is where we ran the registry free of charge. Later on, after CouchOne was aquired by Membase and became Couchbase, it decided to break off the hosting company and give/sell it to Jason Smith, which became IrisCouch.

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Possible solutions

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

	"vim.showMarksInGutter": false,
	"vim.foldfix": true,
	"vim.surround": true,
	"vim.easymotion": true,
	"vim.easymotionKeys": "asdghklqwertyuiopzxcvbnmfj",
	"vim.leader": "<space>",
	"vim.normalModeKeyBindingsNonRecursive": [
	{
	"before": [":", "w", "<CR>"],

	#include "FastLED.h"

	// FastLED "100-lines-of-code" demo reel, showing just a few
	// of the kinds of animation patterns you can quickly and easily
	// compose using FastLED.
	//
	// This example also shows one easy way to define multiple
	// animations patterns and have them automatically rotate.
