On Beyond Lambda: Chess Clocks with ClojureScript

http://onbeyondlambda.blogspot.com/2014/05/chess-clocks-with-clojurescript.html

Thursday, May 22, 2014. Chess Clocks with ClojureScript. Recently I watched a talk. By David Nolen about Clojure's core.async library. For anyone who wanting to learn about core.async, this talk is a great place to start. In the talk David demonstrated a process function that used one channel as a control, to turn off and on output on another channel. He did not have time to go into detail about how it worked, so I wanted to build something with it to make sure I understood it. Each time through the loop...

On Beyond Lambda: February 2014

Sunday, February 23, 2014. Take the Machine Learning Class at Coursera. Coursera is offering its Machine Learning. Course again, beginning March 8, and I highly recommend it. You already know the obvious, that it is a course on an incredibly timely career skill and it is free, but until you take the course you can't know just how good the course really is. You have the time. When I took the class, there was extra time built in to the schedule to allow people who started the course late to stay on pac...

On Beyond Lambda: Asynchronous Naiveté

http://onbeyondlambda.blogspot.com/2014/04/asynchronous-naivete.html

Wednesday, April 9, 2014. This post has been heavily edited. Initially it was describing some behavior I didn't expect using core.async in both ClojureScript and Clojure. It turns out the behavior I observed in ClojureScript was a bug, that has now been fixed. The Clojure and ClojureScript versions can still behave differently than each other, depending on the lifetime of the main thread in Clojure. I have rewritten this to focus on that. Let [c (chan 1)] (go (.log js/console (! C) ) (go (! C) ) (go (!

On Beyond Lambda: March 2014

Friday, March 28, 2014. Simulated stock ticker with core.async. I created a simulated stock ticker in Clojure using core.async. Ns ticker.core (:require [clojure.core.async :refer [chan. Timeout go] :as async]). In core.async functions in your program communicate over channels. There are several ways to put items into a channel and take them off, but in this project only uses! These functions must be called within a 'go block'. I have a couple of utility functions for adding some randomness to the price ...
