| ;; # EMULATING DATOMIC EXCISION VIA MANUAL DATA MIGRATION | |
| ;; ************************************* | |
| ;; ## Introduction | |
| ;; ************************************* | |
| ;; This Gist demonstrates a generic way to migrate an entire Datomic database | |
| ;; from an existing 'Origin Connection' to a clean 'Destination Connection', | |

Sorry, I have to disagree with the entire premise here.
A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.
Mastery comes from a combination of at least several of the following:
| (defn animate-value | |
| [start-val end-val duration] | |
| (let [decrement? (< end-val start-val) | |
| transmit-chan (chan) | |
| cancel-chan (chan) | |
| animation-interval 40 ;40 ms interval - 25fps | |
| steps (/ duration animation-interval) | |
| full-range (- start-val end-val) | |
| per-step (util/abs (/ full-range steps)) | |
| state (atom start-val) |
| (use '[datomic.api :only [q db] :as d]) | |
| (def uri "datomic:mem://accounts") | |
| ;; create database | |
| (d/create-database uri) | |
| ;; connect to database | |
| (def conn (d/connect uri)) |
