For those using Node.js, the same is
var len = Buffer.byteLength(a_string, 'utf8')
WebGL is mentioned on that page. I'm not sure if it was updated since you looked.

The big question is if Heroku will suddenly support a fairly large number of long-lived connections to a Node.js hosted app, and how pricing would work. Developing real-time apps and custom servers are how Node.js really shines. A WebSockets module took only a few hours to develop for instance.
I'm curious about the "fanout" name which immediately made me think of a message broker like RabbitMQ on the backend somewhere. I guess "fanout" here means 1 client to fanout.js to N >> 1 other clients.
There are a number of similar projects popping up like this one as of late for Node.js. NodeRed, fanout, dealer, etc.
That's great. Node.js makes previously "complex" things a little easier to setup and play with.
Redis has native pubsub for a few weeks. A client can subscribe to channels by name or pattern, and publishers can publish messages to channels.
The ruby, python, and node.js clients support non-BLPOP pubsub. We are starting to see some layers added atop this (e.g. NodeRed).

I fully admit to having no idea what this refers to, but I'm scared anyway.
Wow! That was really neat!
As someone who witnessed the events of 9/11 in NY from across the river in Hoboken, NJ this was fairly terrifying too. I was not expecting to have that association when I clicked the link!
mootools made javascript a better language? Javascript is a wonderful language regardless of the availability of good tools and libraries.
ODE has been around for years. Did something big happen? Why is this here?
Somewhere Jodie Foster just threw off her headphones, jumped off the hood of her car, and frantically went to investigate. She won't find much. (hint: 3-D, not 2-D).
Nice, good to see more people coming to Node.js. These things are like the modern "Hello, World!".
Here's one I hacked up in 10 minutes. It's 40 LOC.

The big problem with this is that it's just one server. I'm working on something called "NodeRed" (har har) that lets one scale out the frontend using Redis for communication. It's generic enough to do PUBSUB, chat, games, etc.
Here's an overview.

I developed the/a Node.js client for Redis if you care to dive into this stuff:

I am doing something similar with my redis-node-client as a base.

Ask tocomment: try it and let us know!
Suggestion: temporarily disable the "next reel" button for a duration of time proportional to the frequency of my clicks thereupon. Make me watch the reels instead of trying to satisfy my urge to see "what's next?"
"The weird thing about C is that its not even prefixed like Clojure (+ 2 2), instead all operators are scattered between the arguments!"
Please tell me he is kidding. Maybe I don't get out of my cave often enough but it seems uncommon that someone could grok FP bypassing C altogether.

Initially, Redis required one's dataset to reside in RAM. With its VM implementation, Redis may swap to disk values. Keys must always reside in RAM.
I see. My (wrong) understanding was that EM used a thread pool to do file I/O like Node.js. It appears to add the file descriptor to the event loop's watch list.
Honest question: is there a purely event-driven I/O framework (no threads anywhere)?
The one that a lot of people have gotten excited about recently is Node.js and that uses threads for file I/O (libeio).
I learned Tcl back in college (say 15 years ago) and have not used it since. However, while investigating things like EM and Twisted, I for some reason thought of Tcl. I (and others [1]) asked on the Tcl mailing list about creating a "C10K" server in Tcl but unfortunately Tcl does not have support for epoll, kqueue, etc. at this time.
