The freeCodeCamp open source community runs Medium’s largest technical publication. Each week, we publish more than a dozen stories on development, design, and data science.

For the longest time, I served as the publication’s sole editor. I edited and published more than 1,200 submissions. But we have always received way more high-quality story submissions than I had time to publish. So I finally admitted to myself that I needed help.

Even though freeCodeCamp reaches millions of people each month through Medium, YouTube, and our coding platform, we’re a small donor-supported nonprofit. We lack the resources to hire professional editors.

Today, the freeCodeCamp community turns 1,000 days old. We’ve accomplished a lot together in that time:

  • 6,000+ campers have gotten their first developer job.
  • 8,000+ other campers — who already had developer jobs — have used their new skills to get promoted or transition into even better jobs.
  • Campers now code together at freeCodeCamp study groups in 2,000+ cities around the world.
  • Together, campers have built open source tools used by dozens of nonprofits.
  • The community now runs Medium’s largest technology publication.
  • The community now runs a popular YouTube channel.
  • Thousands of people get help with coding every day on…

“Network” by Michael Durst

This Wednesday, websites, online communities — and all the Americans who use them — will come together to sound the alarm about the Federal Communication Commission’s attack on net neutrality.

Here’s how you can join the protest and spread the word.

Right now, new FCC Chairman and former Verizon lawyer Ajit Pai has a plan to destroy net neutrality and give big cable companies immense control over what we see and do online. If they get their way, the FCC will give companies like Comcast, Verizon, and AT&T control over what we can see and do on the internet. …

An Amazon engineer built a real-time multiplayer game called StockStream, where strangers invest $50,000 of his real-life money in the stock market.

Here’s how it works:

  • Anyone can join the Twitch channel and vote to buy or sell stocks by typing commands like !buy APPL into the chat room
  • Every five minutes, the game will execute the one transaction that the most players voted for during that period
  • The game tracks which players voted for which transactions, and uses the short term capital gains to calculate high scores.

So far, the portfolio has fluctuated around its initial $50,000. …

freeCodeCamp is now the largest technology publication on Medium. And as its sole editor, I get way more high-quality story submissions than I have time to edit and publish.

This means that I’m the biggest bottleneck — between all the developers, designers, and data scientists writing these amazing stories — and a growing audience that’s eager to read them.

Even though freeCodeCamp.org reaches millions of people each month through Medium, YouTube, and our coding platform, we’re a small donor-supported nonprofit. We lack the resources to hire professional editors.

This said, a lack of resources hasn’t stopped us in other areas…

Yesterday, a market where people trade the Bitcoin-like cryptocurrency Ethereum crashed instantly.

The value of Ether (the Ethereum currency) plunged from about US $300 to $0.10 in seconds. Then it bouncing right back up to $300.

Here’s how this extremely unlikely event unfolded:

  1. Around 12:30 pm PST the price of Ether — which had been trading on the GDAX currency exchange at around $300 — suddenly dropped to $0.10. The official explanation is that a trader placed a multi-million dollar order to sell Ether.
  2. In the chaos, computers sold off Ether in automated, price-triggered “sell” orders. …

If you’re a tax-paying American, you may wonder what the shadowy National Security Agency (NSA) is doing with your money.

Well, aside from stockpiling vulnerabilities in old versions of Windows, and writing viruses that destroy nuclear centrifuges, the NSA builds and open-sources some pretty cool tech:

  • goSecure — a portable Virtual Private Network (VPN) system built with Linux and a Raspberry Pi
  • Secure-Host-Baseline — a guide for configuring Windows 10 and Windows Server 2016 to Department of Defense “Secure Host Baseline” standards
  • WALKOFF — an active cyber defense development framework enabling you to write and deploy code across WALKOFF-enabled orchestration…

Today Bali Balo, a French designer and developer, published a new piece: a cube suspended in darkness that rotates on its own. As it does, it reveals different sides, each offering a glimpse into a different world:

  • a game of 3D pong
  • nested 3D shapes that slide around as the cube tilts
  • a field of stars whizzing past as if traveling at near light speed
  • a surreal humanoid figure that seems to tumble forever through space

Bali Balo is famous on CodePen not only for these explorations of geometry, but also for building a pure-CSS Minesweeper game.

That’s right —…

A team of developers just launched an open source search engine that will show you how to learn pretty much anything. It works by clustering resources into “mind maps.”

Here’s part of their mind map for web development:

Google Maps when you turn off JavaScript

A Berlin-based web developer — who codes JavaScript for a living — decided to go an entire day without JavaScript.

Let’s face it — in an insane world where the average webpage is 2.4 megabytes — the same size as the 1993 game Doom — turning off JavaScript completely can seem like a sane thing to do.

Well, here are her main observations after disabling JavaScript in the browser for a day:

  • The web is really fast without JavaScript
  • There aren’t any ads. No auto-playing videos or “tell us your email address” pop-ups.
  • But… a lot of websites don’t work…
