What goes on in the LJC?

We run a variety of regular events ranging from social events and technical presentations to our full day unconference. On top of the events we run prize draws and have an active mailing list/forum. We support the Graduate Development Community in London and promote London based Open Source Software projects where possible.

Who can join?

Membership is restricted to Java developers working in or around London (or those hoping to train in Java, or relocate to London). Membership will not be granted to those involved in the recruitment industry.

Is there a fee to Join, is there a fee for the events?

It’s completely free to join and 99% of our events are completely free. The only event which is charged for is the Unconference, the charge is minimal and it is there to cover refreshments on the day.

Do you have to go to every presentation?

Absolutely not – it’s completely up to you which events you attend and which you don’t. Every event attracts a different crowd.

Where are the events held?

Europe's Premier technical training company, Skills Matter (Barbican) sponsor most of our events by providing the venue.

LJC - Redis: Caching, Multi-Model DB and Event Processing with Java Abstract

*** This is a placeholder for the event being run on Eventbrite. Please sign up with your full name at https://www.eventbrite.co.uk/e/ljc-redis-caching-multi-model-db-event-processing-with-java-abstract-tickets-184759519697

Redis: Caching, Multi-Model DB and Event Processing with Java Abstract

About the event

Everyone has heard about Redis, the most adopted in-memory database - but have you reached a point where you can say "I know Redis" ? We'll bring you there!
Redis provides powerful distributed in-memory data structures but also multi-model database capabilities for dealing with time series, full text search and secondary indexes, graph, JSON as well as event processing. All this with first class Java integration with multiple API libraries supporting sync, async, reactive programming and stream processing.

We will walk you through the basics of Redis with Java and expand how modern microservices applications can leverage the multi-model nature of Redis to simplify building real time applications.
Through some code and real world examples you will understand how Redis architecture can be scaled with Redis.

About the Speakers

Kamran Yousaf
Kamran Yousaf is a Solution Architect at Redis with more than sixteen years experience in varied roles and technologies. He specialises in development of distributed, high performance, low latency architectures. During this time he has worked with a wide range of technologies and architectures from rule based development, grid and low latency application to enterprise file sync and share. Most recently he was CTO at a UK startup SME, a leader in enterprise file sync and share. Previously he has worked at GigaSpaces, BEA and Versata.

Alexandre Vasseur
Alexandre is heading Redis technical field engagements in EMEA. He and his team are in charge of technical awareness and solution architecture for customers, prospects and partners in that region to put Redis adoption on the right track when developing modern applications using Redis in-memory and multi-model database, and also when bringing it to production on any platform and clouds at any scale.
Previously Alexandre was leading the Pivotal technical field around Spring, Cloud Foundry and Kubernetes. In the earlier days of Java, he worked on the BEA JRockit JVM, Aspect Oriented programming and was a committer in Eclipse AspectJ.

LJC Virtual Meetup: Lunchtime Lightning Talks

Online event

***This is a placeholder for the event being run on Eventbrite. Please sign up with your full name at https://www.eventbrite.co.uk/e/ljc-lunchtime-lightning-talks-tickets-189559215717***

We're back with our 35th LJC Lunchtime Lightning Talks session.

The first part will be a series of lightning talks (5-7 minutes) on a variety of topics.

The second part will be a discussion on tech speaking.

We will aim to have a maximum of 4-5 lightning talks. You can tune in and tune out as you wish. The talks can be on anything you’re interested in.

We will keep it very light (pardon the pun) and hopefully it will be a bit of fun before the weekend to enjoy over your lunch hour.

As we’ve often talked about, lightning talks are a great opportunity to try, test or hone your speaking and presentation skills. They are usually under 7 minutes, with 2 minutes of Q+A.

This event is organised by RecWorks on behalf of the London Java Community.

Distributed Transactions in a Service Mesh

Online event

*** This is a placeholder for the event being run on Eventbrite. Please sign up with your full name at https://www.eventbrite.co.uk/e/ljc-distributed-transactions-in-a-service-mesh-tickets-180737148677 ***

About the Event

As we go deeper into cloud-native applications, microservices are becoming a part of any developer’s life. Together with Kubernetes and service meshes, they became the de facto standard in the industry. However, one question arises with microservices: How to implement distributed transactions in such an environment?

In this talk, we will discuss distributed transaction methodologies, talk about real-life scenarios, and provide a hands-on resolution in the Istio service mesh using the Hazelcast application platform. The attendees will easily understand the distributed saga pattern, backend architecture, and the topology of the solutions with live demonstrations.

About the Speaker

Alparslan works for Hazelcast as a Software Developer. He is a passionate Java & Golang developer and loves to think in a distributed way. Prior to joining Hazelcast, Alparslan worked in several Java projects including a web search engine and enterprise financial anti-fraud solutions. He also contributes to open-source projects like Apache Nutch and is currently a PMC member in Apache Gora. Alparslan holds an MS degree in Software Engineering of Distributed Systems from Kungliga tekniska hogskolan in Stockholm, Sweden.
