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

In Rails 3

NOTE: This post now lives (and kept up to date) on my blog: http://hakunin.com/rails3-load-paths

If you add a dir directly under app/

Do nothing. All files in this dir are eager loaded in production and lazy loaded in development by default.

If you add a dir under app/something/

This list now exists over at http://juliepagano.com/blog/2013/11/02/101-off-limits/ and will be updated there.

I keep saying that impromptu, unwanted feminism 101 discussions are exhausting and not a good use of my resources. Then people ask what I mean by 101, so I'm starting to make a list. This list will change over time - I recommend checking back.

I highly recommend checking this list before engaging with me about feminism if you're new to it. It'll save both of us a lot of time and frustration.

Diversity in tech

Women aren't equally represented in tech because biology

Nope. This argument is bad and the science does not support it. Unfortunately, every time you say this out loud, you are contributing to cultural problems that do decrease the number of women in tech.

Development box installation guide

This guide will show how to setup a VirtualBox similiar to an Ubuntu 12.04.1 server for use with Amazon EC2.

Covered in this guide:

VeeWee: Tool for building base boxes which will be used by vagrant
Vagrant: Tool for managing virtual machines with an easy to use CLI
Librarian: Bundler for chef cookbooks
Chef-solo & Knife solo: Tool for automating installing and management of servers

	Here's the idea,

	You work in tech. You're in the NYC area.
	You care about "people" issues. You think the hardest problem in computing is "people".
	You are interested in how we work. How to structure work. How to work together.
	How to help your colleagues succeed.

	And...

	There's so much to learn:
