Things that programmers don't know but should

(A book that I might eventually write!)

Gary Bernhardt

I imagine each of these chapters being about 2,000 words, making the whole book about the size of a small novel. For comparison, articles in large papers like the New York Times average about 1,200 words. Each topic gets whatever level of detail I can fit into that space. For simple topics, that's a lot of space: I can probably walk through a very basic, but working, implementation of the IP protocol.

Step 1: Server Credentials

This assumes you are now connected to the server via SSH.

• sudo -s Enter root mode for admin access
• groupadd devgroup Create new group to be later granted access to /var/www/html

Creating a new Root User

• useradd -G root,devgroup masterdev Create new root user. Also add to the devgroup
• passwd masterdev Change password for the new root user
• At this point, you'll need to input your new root user's new password

AWS ELB with Node.js and WebSockets

This assumes that:

• You are using Nginx.
• You want to accept incoming connections on port 80.
• Your Node.js app is listening on port 3000.
• You want to be able to connect to your Node.js instance directly as well as via the load balancer.

####1. Create load balancer

To remove a submodule you need to:

• Delete the relevant section from the .gitmodules file.
• Stage the .gitmodules changes git add .gitmodules
• Delete the relevant section from .git/config.
• Run git rm --cached path_to_submodule (no trailing slash).
• Run rm -rf .git/modules/path_to_submodule (no trailing slash).
• Commit git commit -m "Removed submodule "
• Delete the now untracked submodule files rm -rf path_to_submodule

@mafintosh said most of this, I just wrote it down

how to destroy/end streams in node >= 0.10

• usually you call .destroy() if it has .destroy
• if it doesnt have .destroy you are out of luck and the stream should upgrade to use e.g. newer through2
• in request you call .abort() (this should get fixed to use .destroy())
• .end() tries to end the stream gracefully

what about close
