Summary
Daniel Spiewak and Aaron Bedra take a look at code verifying starting with Tony Hoare’s paper on testing(1969), type theory, and language-integrated proof systems.

Bio

Daniel Spiewak has worked over the years with Java, Scala, Ruby, C/C++, ML, Clojure and several experimental languages. He currently spends most of his free time researching parser theory and methodologies. Aaron Bedra is a Senior Software Engineer at Groupon working on Groupon’s Now! real-time deals platform. He is the co-author of Programming Clojure and Practical Software Security.

Strange Loop is a multi-disciplinary conference that aims to bring together the developers and thinkers building tomorrow's technology in fields such as emerging languages, alternative databases, concurrency, distributed systems, mobile development, and the web. Strange Loop was created in 2009 by software developer Alex Miller and is now run by a team of St. Louis-based friends and developers under Strange Loop LLC, a for-profit but not particularly profitable venture.

Extreme hand-waving by Eric Smith

I really hate to be so negative, but this is an interesting and potentially important topic, and it is not helped by this kind of childish presentation style and dismissive conclusion. Being 'fun' is not a substitute for clarity.

Even so, thanks for putting in the time to research the topic and make sense of it. Just wish it hadn't been turned into nonsense.

Re: Extreme hand-waving by Tom Crockett

It's not at all nonsense, though it is presented in a somewhat roundabout style. I wonder if it was meant to be an homage to Hofstadter: a dialog which slowly and with much wordplay teases out an idea. I too prefer the more direct presentation style (I could only get through half of Goedel, Escher, Bach).

Pontificating on Correctness by Yuriy Zubarev

It's an entertaining presentation if you're into Haskell Curry, Alvin Howard, Gödel and likes. One practical take away and a constant reminder is that you can never have enough assertions with your tests or type systems, you can only increase confidence.

Code coverage is a lie? Mock objects are useless? by vicki kozel

I didn't quite get why the presenters called code coverage a lie. A lie about what? I suppose they find mock objects useless too... Is that because they find isolating a unit of code under test useless, or entire exercise of unit testing useless?
