When 100 developers and 1 robot signed up for the February edition of Hack the Tower, across many technical communities in London, I could tell it was going to be a big event.

Heading out for a full day of coding @HackTheTower - excited about what people will create today #LSDC #LondonScala #LJCjug #LdnClj #robots

Developers arrived from different communities, including

• London Scala user group
• London Clojure community
• London Java Community
• London Salesforce developers
• London Software Craftsmanship>

@sandromancuso Yeah our little team is awesome, I believe we’re the last ones still coding :) @HackTheTower idea is great, I truly enjoy it!

Leiningen is a project automation tool (think build tool and them some) that uses a Clojure macro to make it easy for Clojure developers to manage their project lifecycle.
