# This week's activity

This week we will try something new by using Clojure(script) to create a GUI for our game (minesweeper). In the previous session we made a Clojure version of minesweeper but is no fun playing the game through the REPL, so we will try to make it better by creating a GUI.

#Location

Skyscanner is based on 155 St Vincent Street. It is a Glass / Steel building with big copper square round the entrances. There are two entrances but Skyscanner is only in 155, the one further up the hill of St Vincent Street.

#Registration

When registering on the day you will need to provide your full name & email address.

#Food & drink

Food & drink will be provided!

# Next two dates for the dojo:[masked].2019

# How the event works

After we have decided on some challenges for the evening, we break into small groups (2-4 people) and see how far we can get. After about 90 minutes we get together and share what we have learnt, showing code and demo's of it in action.

# Requirements

If you have a laptop with a working Clojure environment please bring it along. As we arrange ourselves into small groups, if you don't have a laptop you can still join in.

We are collecting all our kata solutions here, take a peek at what we've done so far (github.com)

# Discussions

We’ll be discussing the meetup on the london-clojurians mailing list (groups.google.com)

If you want to know how to run your own dojo or get an idea of what dojos are like you can read more at otfrom.wordpress.com

# Background

Clojure is a JVM language that has syntactically similarities to Lisp, full integration with Java and its libraries and focuses on providing a solution to the issue of single machine concurrency.

Its small core makes it surprisingly easy for Java developers to pick up and it provides a powerful set of concurrency strategies and data structures designed to make immutable data easy to work with. If you went to Rich Hickey’s LJC talk about creating Clojure you’ll already know this, if not it’s well worth watching the Rich Hickey “Clojure for Java Programmers” (skillsmatter.com) video or Stuart Halloway “Radical Simplicity” (skillsmatter.com) video.
