• Lunchtime Lightning Talks

    London

    ***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-116705006817?aff=meetup ***

    This event is being run in partnership with the London Java Community.

    We're back with our 10th Lunchtime Lightning Talks session with talks including 'Hypermedia-Driven RESTful Web Service with Clojure, Liberator, HAL, and OpenTelemetry', 'How technology empowers remote working ' and more.

    This is going to be run in a similarly informal style to an unconference, in that the right talks will be done by the people that are there. 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. If you'd like to give a talk at the event please get in touch or sign up on Eventbrite and select the "I'd like to give a lightning talk" ticket.

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

  • Who Do You Want to Be? & The Software Developer's Guide to Fun in the Workplace

    Sign up on Eventbrite for location

    The LJC would you like to invite you to join them on Tuesday 10th July when we're very pleased to welcome Joe Schmetzer and Dr Holly Cummins.

    Talk 1 Details:

    Congratulations! You're working in a software team. Now what? Not everyone has a long term plan, or even needs one. But... if you don't have a clear picture of what you like and dislike about your job, your career can wander aimlessly and end up in places you may not like. In this talk, Joe offers advice and guidance about nudging your career to maximise your happiness and success.

    About The Speaker:

    Joe Schmetzer creates software, aiming to achieve business goals and delight the user. Joe’s blog ( https://exubero.com/) gives you an insight to his current thinking and activities.

    Talk 2 Details:

    An in-depth look at what makes software development a roller coaster where the highs of 0 compiler warnings are quickly cancelled out by the pain of long hours, bad requirements, endless configuration, clueless managers and a plethora of other issues which make death by a thousand cuts seem like a good idea…. They will answer questions such as: “Why is programming often called an art despite having its underpinnings in formal logic?” “How can I rediscover the delight I felt when I first started coding?” “What’s that rush I feel when my test passes? Am I addicted to TDD?” Combining Psychology, Philosophy and Computer Science, Dr Holly Cummins will present a series of practical tips to help you rediscover the euphoria that you felt the very first time a metal box in front of you came to life and cried out “Hello World”.

    About The Speaker:

    Holly Cummins is the technical lead of IBM’s Bluemix Garage London, and the former delivery lead for the WebSphere Liberty Profile. She is a co-author of Enterprise OSGi in Action and has spoken at JavaOne, Devoxx, JavaZone, The ServerSide Java Symposium, JAX London, GeeCon, and the Great Indian Developer Summit, as well as a number of user groups. Outside of her work at the Garage, Holly enjoys, cake engineering (“baking”), running, and sewing.

  • JBake : Static site generation...on the JVM

    This is a placeholder for the event which is being run on Eventbrite. See the full details and register here: https://www.eventbrite.co.uk/e/jbake-static-site-generationon-the-jvm-tickets-43482990796

    The LJC would like to invite you to join them on Tuesday 27th March where we're pleased to announce Jonathan Bullock will be discussing JBake: Static site generation on the JVM.

    Static is the new dynamic. There are considerable benefits to statically generated sites when compared to dynamic sites. This talk will show you can forget Ruby, Python or Go and use the JVM: it is the perfect platform to use when it comes to generating a static site or blog.

    In this talk you'll find out more about the benefits of static sites, what features JBake provides and how it can be used to produce a static site.

    Speaker Bio:

    Jonathan Bullock is a Senior Web Developer and creator of JBake. He has a passion for the internet, gadgets and is a fan of far too many sports. Check out his website - http://jonathanbullock.com/ or follow him on Twitter - @jonbullock

    Tonight's venue and refreshments are kindly provided by Oracle.

  • How the JVM executes Java

    Skillsmatter (CodeNode)

    When Java was released in 1995 it was slow, a reputation it has carried for many years... Today Java can give performance that is comparable to C++ and can emit instructions that are more optimal than code which is statically compiled. But how? This talk will take a tour of code and the journey through the JVM and the optimisations in between. Using practical examples, JVM flags and the Open Source JIT Watch we will explore what the JVM does in an adaptation of the classic Hello World program, you'll never look at Java in the same way again.

    James Gough is a technical trainer and writer specialising in Java. He spends the majority of his time teaching advanced Java and concurrency courses to developers with varying technical backgrounds. He serves on the Java Community Process Executive Committee and contributed towards the design and testing of JSR-310, the date time system built for Java 8. James is a regular public speaker and helps organise events at the London Java Community.

  • Constraint solving in Java with OptaPlanner

    Skillsmatter (CodeNode)

    What’s the shortest trip to visit all European capitals? Or the cheapest vehicle routing schedule to restock all our retail stores? How do we optimize our cloud machines? When do we assign nurses to shifts in our hospitals to make them as happy as possible? Which crops do we plant on which fields for the optimal revenue? What’s the fairest tennis club schedule? Which algorithms work well and scale out on these kind of planning problems? Certainly not Brute Force or other exhaustive heuristics!

    In this session, we will:

    - Introduce constraint satisfaction optimization

    - Demo a few use cases

    - Use weighted hard and soft constraints to formalize business goals

    - Walk through a bit of example code in Java of the open source constraint satisfaction solver OptaPlanner

    - Explain how continuous planning or real-time planning works - Deal with scalability challenges by using heuristics and metaheuristics (such as Tabu Search and Simulated Annealing).

    Geoffrey De Smet is the founder and project lead of OptaPlanner (www.optaplanner.org), the leading open source constraint satisfaction solver in Java. He enjoys assisting developers optimize challenging planning problems of real-world enterprises. He also participates regularly in academic competitions. He started coding Java in 1999 and he regularly contributes to other open source projects too.
