Kodsnack 294 - The immediate feedback loop, with Dan Lebrero

<p>Fredrik talks to Dan Lebrero, long-time Java developer turned Clojure developer, REPL-user, efficiency-thinker and more.</p> <p>We discuss the wonders of REPL-driven development, and how it works. Dan opens Fredrik&rsquo;s eyes somewhat to the possibilities and how they happen. The REPL can complement TDD, and also probably kill test writing for those not completely test infected.</p> <p>We also discuss finding good tools, learning them, and of course building your own tools. Have you learned Bash as well as it deserves?</p> <p>Thank you <a href="http://www.cloudnet.se">Cloudnet</a> for sponsoring our <a href="http://en.wikipedia.org/wiki/Virtual_private_server">VPS</a>!</p> <p>Comments, questions or tips?
