What we're about

An open and friendly community that supports the adoption and practice of Clojure in any of its forms.

Clojure is a great way to learn functional programming thanks to a small and well crafted syntax and focus on simplicity. Clojure is a powerful, productive and fun language, based on LISP and hosted on Java, JavaScript, Microsoft CLR, GraalVM, and Golang.

London Clojurians is a very active community with several events per month, including technical talks, coding dojo's, hackdays and a yearly conference. We hope you will join us and increase your knowledge and appreciation of Clojure and add your own experiences to our community.

Upcoming events (5+)

London Clojure Dojo at ThoughtWorks (Soho)

ThoughtWorks London office

The goal of the Clojure dojo is to raise the confidence and experience levels of those that attend through practical exercises. These events support those new to Clojure as well as more experienced developers from the London Clojure community. Suggestions for practical coding challenges are added on http://www.londonclojurians.org/code-dojo/ as we find them and we also have a Github repository https://github.com/ldnclj # 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. # Discussions We’ll be discussing the meetup on the london-clojurians mailing list (http://groups.google.com/group/london-clojurians/) 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 http://otfrom.wordpress.com/2010/10/26/faq-how-much-do-i-need-to-know-before-i-come-to-the-dojo/ # 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” (http://skillsmatter.com/podcast/java-jee/clojure-for-java-programmers) video or Stuart Halloway “Radical Simplicity” (http://skillsmatter.com/podcast/java-jee/radical-simplicity) video.

Clojure Weekly Study Group

Needs a location

A weekly Clojure study group for those starting their Clojure journey or looking to practice their Clojure and understand functional programming via practice. The study guide is published at http://practicalli.github.io/clojure/study-guide.html This event will usually run on Saturday Mornings at 11am. All sessions will be broadcast and you can watch live or the recording if you want to catch up afterwards. Once a suitable venue if found there you can also join in person. The study guide topics each week are published in advance, and feedback as to what should be covered is most welcome. Thank you London Clojurians

Blockchains and Immutable Databases in Clojure

Skillsmatter (CodeNode)

Please sign up at SkillsMatter, so we get a big enough room https://skillsmatter.com/meetups/12187-blockchains-and-immutable-databases-in-clojure ## Blockchains and Immutable Databases in Clojure by Moe Aboulkheir https://nervous.io/about/ Drawing on implementation and design experience, this talk delineates the boundary between blockchains, as commonly realized (e.g. Bitcoin, Ethereum), and immutable databases (Datomic, etc.). We'll explore areas where blockchains might benefit from paying attention to immutable databases, and imagine what a permissionless, collaboratively schematized global database --- a blockchain database --- might look like. ## Approximate schedule: 18.00 Doors open 18.30 Intro and Lightning talks 18.45 Blockchains and Immutable Databases in Clojure 19.30 Discussions / wrap-up --- Thank you to anyone interesting in speaking, please either complete https://bit.ly/ldnclj-speak or email [masked] or reach out to @jr0cket on Clojurians slack or Twitter. --- Our monthly gatherings are often varied, from talks to workshops to public speaking training and many things in between. They are a chance for anyone in the community to share their experiences. We have talks from well-known speakers in the Clojure/Script community and support and encourage those new to public speaking to share their experiences. Everyone has a different journey in life, so we all have something to share We also have workshops at our gatherings and we can book a room with desks and power for everyone to work on. Past workshops include Transducers, ClojureScript games, and Spacemacs for Clojure development. Our gatherings are typically on the first Tuesday of each month (except December when we have our annual ClojureX conference. Thank you London Clojurians
