Datomic and LLVM

Welcome to our last meetup before the summer holiday period. We decided to be a little geek-er than usual, as consequence, the topics are more interesting than usual :-)

 

Join us at Green King, 26 June, from 6.30 pm.

 

Datomic (Nicolas Bousquet)

Rich Hickey, the creator of Clojure, has lately created Datomic, a new type of database that is distributed by design, declarative, and embraces immutability data fully. Datomic still has all you can think of in a new modern database like ACID transactions and query language, Datalog.

In this talk, Nicolas Bousquet will present some basic concepts of Datomic, its strength, and why it is an interesting concept.

LLVM (Christophe de Dinechin)

A compiler can be seen from a monolithic point of view where a front-end part creates some intemediate representation (IR) and then a back-end part that creates machine codes from the IR. The back-end codes are typically full of codes specific for the targeted machine.

We can see Java Byte codes and JVM, the most popular target platform of Scala and Clojure, are actually an IR. JVM then provides some optimizations like JIT to specific machines. The JVM approach then allows the programming language designers to focus on the front-end codes and rely on the optimization done in JVM.

LLVM provides IR that allows programming language designers concentrate on the front-end part of their compiler. It is an open source effort, and there have been a lot of languages using it. There is , for example, an effort to do Scala backed up by LLVM.

On this session, Christophe de Dinechin from Taodyne will lead the discussion on LLVM. He is a programming language designer that targets LLVM. So, who can be better than him to share the view of LLVM ?

    Présentations de qualités même si j'ai d'avantage accroché sur Datomic que sur LLVM.

I started the group because there wasn't any other type of group like this. I've met some great folks in the group who have become close friends and have also met some amazing business owners.
