Friday Round-Up: 30th of September – 4th of October

We know we say it too much but we really have had a crazy week here at Skills Matter HQ. Not only have we had an action packed week full of fantastic events but all systems are go for our up and coming conferences. This year has flown past with Haskell eXchange just next week!

Treated with not only the October meet-ups of the London Clojure Community, London Scrum User Group and the very first Big-O meet-up but also two enlightening In the Brains sessions. One from the renowned Giovanni Asporoni and the other from Nicolas Favre-Felix. A massive thank you from all the gang at Skills Matter for learning and sharing.

The week in SkillsCasts
London Clojure Community had a talk from James Adams and Malcolm Sparks on the production of a multi-user Poker application written using Clojure and Datomic. The boys informed listeners how they used Clojure’s currency features to reliably handle a large amount of concurrent players and how they tackled communication between the browser and server. This ones not to miss, even includes a live demo of the actual application giving you a rare opportunity to gain insight into how to use, integrate and deploy Datomic in production!

In The Brain of Nicolas Favre-Felix, Nicolas gave a talk on the history of doing analytics in the NoSQL database. He looked at the relative strengths of normalised and denormalised approaches and looked at how Twitter and Facebook have built a custom denormalised systems over NoSQL to support real-time analytics.

The Big-O meet-up was made up of two talks one from Jurgen Van Gaal on Numerical Optimisation where he gave an overview of multivariate numerical optimisation, covering line search, gradient descent, Newton methods and quasi-Newton. The second talk was from Okash Khawaja who closely followed the example of a chess engine as an application of negamax search and explored the implementation of such a lock-less look up table.

 In The Brain of Giovanni Asporoni, Giovanni gave an interesting talk on some serious and common mistakes programmers make when writing tests. He gave examples from real-code-bases and hints on how to avoid said mistakes.

The London Scrum User Group was given a talk from Casper Below & James Burnett who showed attendees how adapting scrum methods for non-technical teams has kept things moving and improved transparency of workload, of commitment, of agreement, of required consultation and work done, even before the development process.
