Using OTP's observer (appmon replacement) remotely

$ ssh remote-host "epmd -names"
epmd: up and running on port 4369 with data:
name some_node at port 58769

Note the running on port for epmd itself and the port of the node you're interested in debugging. Reconnect to the remote host with these ports forwarded:

$ ssh -L 4369:localhost:4369 -L 58769:localhost:58769 remote-host

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

Serving Django and Twisted using HAproxy

Why?

Because we wanted to achive the following while developing a webapp using websockets:

Static serving (nginx), Django application (gunicorn) and Websockets service (twisted)

Javascript `log` Function

Every time I start a new project, I want to pull in a log function that allows the same functionality as the console.log, including the full functionality of the Console API.

There are a lot of ways to do this, but many are lacking. A common problem with wrapper functions is that the line number that shows up next to the log is the line number of the log function itself, not where log was invoked. There are also times where the arguments get logged in a way that isn't quite the same as the native function.

This is an attempt to once and for all document the function that I pull in to new projects. There are two different options:

The full version: Inspired by the plugin in HTML5 Boilerplate. Use this if you are writing an application and want to create a window.log function. Additionally,
