Supposedly WhatsApp scaled to serving over 1 billion users with Erlang and BEAM.
RabbitMQ, used by Reddit, uses Erlang and BEAM.
Discord uses Elixer and BEAM.
I just traveled down the BEAM rabbit hole. Fascinating story. The Ericsson Computer Science Laboratory cranked out some amazing products in the early 1990's.
Their goal was five nines of reliability for Ericsson telephone switches.
According to Joe Armstrong (an interesting fellow from Ericsson), the AXD301 ATM switch achieved nine nines over a nine-month period using Erlang and BEAM in 2002. That calculates out to 24 milliseconds of downtime.
And yes, it is not that it is just presenting the facts. By me taking control of the direction the questions and answers go, I can flesh out my mental model. I won't retain every little thing it tells me. But I am much farther ahead than before.
Here is what Zach Dive said in the original HN announcement--
Eve is an AI agent harness that runs in an isolated Linux sandbox (2 vCPUs, 4GB RAM, 10GB disk) with a real filesystem, headless Chromium, code execution, and connectors to 1000+ services.
You give it a task and it works in the background until it's done.
I built this because I wanted OpenClaw without the self-hosting, pointed at actual day-to-day work. I'm thinking less personal assistant and more helpful colleague.
The main interface is a web app where you can watch work happen in real time (agents spawning, files being written, use of the CLI). There's also an iMessage integration so you can fire a task asynchronously, put your phone down, and get a reply when it's finished.
Under the hood, there's an orchestrator (Claude Opus 4.6) that routes to the right domain-specific model for each subtask: browsing, coding, research, and media generation.
For complex tasks it spins up parallel sub-agents that coordinate through the shared filesystem. They have persistent memory across sessions so context compounds over time.
I've packaged it with a bunch of pre-installed skills so it can execute in a variety of job roles (sales, marketing, finance) at runtime.
"A college kid at RIT cracked one of the biggest cyberattacks ever seen, mostly from his dorm room. Benjamin Brundage mapped out a botnet called Kimwolf — 2 million hacked Android devices being rented out to launch massive DDoS attacks — by infiltrating hacker chat rooms and sweet-talking insiders with cat memes. His research eventually fed into a federal takedown. The feds are sending him a t-shirt. "
‘I don’t have a girlfriend. But I do know a woman who’d be mad at me for saying that.’
‘I’m against picketing, but I don’t know how to show it.’
‘I haven’t slept for ten days, because that would be too long.’
‘I like to play blackjack. I’m not addicted to gambling. I’m addicted to sitting in a semi-circle.’
I feel the same way about Simon Willison. He's a treasure!
Here's a few of those EF Hutton commercials for your viewing pleasure--
Yep, that's how I feel when Simon Willison speaks!
