/* Keybindings for emacs emulation.  Compiled by Jacob Rus.

 * BEWARE:
 * This file uses the Option key as a meta key.  This has the side-effect

;;; Seed Dependencies for Clojure Projects

;; This file contains Leiningen-style dependencies for many
;; commonly-used Clojure and Java libraries.

;; If you put all of these dependencies in a project.clj file, you
;; will NOT get a working project! However, running `lein deps` will
;; download all of these libraries as well as their transitive
;; dependencies. This is a convenient way to "seed" the local Maven
;; repository cache on a new machine.

Opening and closing an SSH tunnel in a shell script the smart way

I recently had the following problem:

• From an unattended shell script (called by Jenkins), run a command-line tool that accesses the MySQL database on another host.
• That tool doesn't know that the database is on another host, plus the MySQL port on that host is firewalled and not accessible from other machines.

We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like

ssh -L 3306:localhost:3306 remotehost

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style
