We'd like to thank Rich Hickey for a great presentation here in New York City on November 10th, 2016

Rich Hickey is best known for creating Clojure, a functional programming language that runs on the Java virtual machine. Rich is also the inventor of ClojureScript, a compiler for Clojure that targets JavaScript, as welll as Datomic which is a fully transactional, cloud-ready, distributed database.

Rich presented Clojure Spec, a new closure library which helps automate Validation, Error reporting, Destructuring, Instrumentation, Test-data generation and Generative test generation

Our sincerest gratitude for an informative and delightful evening!

( meeting - Tuesday, May 8, 7:00 PM - Presenting Seed: A Metamorphic Software System by Andrew Sengul )

Seed is a new interactive software environment that ties together visual
and textual programming built in Common Lisp. Seed allows you to create
and use programs with customized workflows and a wide variety of
interface modes, including text editors, spreadsheets, tree grids,
interactive vector graphics, 3D voxel environments and more. The system
was built to realize the following principle:

In Seed, there are not interfaces to programs.

In Seed, the interface is the program.

This talk will introduce you to Seed and help you understand its roots
and the problems it's intended to solve. Seed was inspired by my
experience with different software systems and their shortcomings, and
as such it's not just intended to solve a technical problem, but a human
problem that lies at the heart of all software design. Join me on May
8th to learn more.
