February '14 meetup

Our fourth meetup will be hosted at The Dancing Camel courtesy of Wix. This time we'll have one full- and one half-length talk, followed by a 30 minute open discussion on Scala and related topics. Both talks will be given in English, and will be recorded and published.


• 18:00 - Mingling

• 18:30 - Nadav Wiener - Implementing mixfix operators in Scala using macros

• 19:00 - Christopher Severs - My Favorite Bird

"Algebird is an abstract algebra library for Scala developed at Twitter and released under the ASL 2.0 license. It has support for algebraic structures such as semigroups, monoids, groups, rings and fields as well as the standard functional things like monads. More interestingly though are the probabilistic data structures and the accompanying monoids that come out of the box. I'll talk a bit about Algebird in general then take a dive into some of the probabilistic data structures and the more exotic monoids that are part of the standard Algebird package. Time permitting I'll also show you how to make your own monoid for your custom data structures."

• 19:30 - Open discussion

See you there!

    The collections talk I mentioned is "Scala Collections: Why Not?" by Paul Phillips, you can see it here:

      Paul has several lectures of short comings in scala, not only in the collections API, and one of the more poignant ones for me, was his criticism of the compiler code. He claims it is too complex, to thr point they find it very hard to make changes and improvememnts.

      I'm not familiar enough with Scala to fully grok his explanation as to why it is so.

    Agree, session was great and food&beer were awesome. Thanks.

    Tomer, can you share the lecture you mentioned about why Scala collections are bad?
