Prefer using SSH over HTTP(S) for git.
In your ~/.gitconfig file:
[url "git@github.com:"]
insteadOf = http://github.com/
insteadOf = https://github.com/Wants to be the "cryptographic right answers" document, but for SSH.

Maybe have Glitch monitor it?

A layer in between an application and unix TCP sockets that make the sockets robust to TCP disconnects including roaming and connection failure. Implements some of the tmux user experience, even works with the tmux control center (tmux -CC). Buffers bytes written and read so they can be replayed in the event of a disconnection. Starts with SSH to make the initial connection and authentication. After that, it uses its own encrypted network protocol.
Apache Guacamole is a clientless remote desktop gateway. It supports standard protocols like VNC, RDP, and SSH.
We call it clientless because no plugins or client software are required.
Thanks to HTML5, once Guacamole is installed on a server, all you need to access your desktops is a web browser.

A good blog post about using SSH's little-known proxy functionality to tunnel traffic back through your home network to prevent eavesdropping. The best thing is, you don't have to set up a proxy on the other end because SSH does it for you.
Have you ever tried to SSH into one of your boxes, only to get dropped with a "Too many authentication failures" error? Here's how to fix it (it's a server side problem).
How to run FTP over an SSH tunnel to another server. It involves setting up a couple of port forwards and FTP in passive mode.
An official implementation of the rsync protocol for Windows. Has a handy wizard which walks you through picking the directories you want to back up, the host and directory you want to back up to, how you want to connect (hint: if you're backing up to a Linux box, Windows Backup Agent natively supports SSH!), and when you want the backup jobs to run. Windows Backup Agent will then run in the background of your Windows machine and periodically SSH into another machine to rsync files over to it to back them up. I use it on my Windows machines at home and I'm very pleased with it.

A remote login utility that is mobile aware, i.e., your link can drop (say, if you're on a cellphone) and come back up later, and your session will still be running. It's kind of like GNU Screen, actually. Also allows editing of lines prior to sending with the enter key. Adapts to network latency.

Several different ways of configuring SSH on servers to use multiple authentication methods in succession for greater security.
An experimental ssh and telnet server daemon written in python, meant for developing things like a BBS, a MUD, or a MOO. Built on top of Miniboa, Blessed, SQLitedict, Paramiko, and web.py. web CURSES enabled. Supports ANSI art.
A quick and easy chat server written in golang that you access through ssh. It's pretty basic and straightforward, and might make a good easter egg.

A chat server written in go that implements ssh. SSH to the box in question and it drops you into a simple IRC-like chat. Your username in chat is your username on the machine you're SSHing in from.
Fabric is a Python module which lets you write scripts in Python that carry out just about any administrative task you might need to carry out without having to fuss with os.shell(), .popen(), or anything else. SSH's into a system (even localhost) and does what you tell it to.
