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 Front Endgineers London.

About the event
Apache Maven is seen by many developers as the defacto build tool in the Java space. Since its early days back in April 2002, Maven has helped developers build projects and assemble artifacts. On the surface not much appears to have changed in the design, structure, and build file syntax, but in reality, there are quite a good number of features that have been added through the years that make Maven a powerhouse.
Come to this talk if you want to learn more about these hidden nuggets and make the most of your Maven builds.

LJC Virtual Meetup: An Experiment in Continuous Deployment of JVM applications
Description changed:
***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-virtual-meetup-an-experiment-in-continuous-deployment-of-jvm-applications-registration-105284538890?aff=meetup ***
About the event
A couple of years ago, continuous integration in the JVM ecosystem meant Jenkins. Since that time, a lot of other tools have been made available. But new tools don’t mean new features, just new ways. Besides that, what about continuous deployment? There’s no tool that allows deploying new versions of a JVM-based application without downtime. The only way to achieve zero downtime is to have multiple nodes deployed on a platform, and let that platform achieve that e.g. Kubernetes.
And yet, achieving true continuous deployment of bytecode on one single JVM instance is possible if one changes one’s way of looking at things. What if the compilation could be seen as changes? What if those changes could be stored in a data store, and a listener on this data store could stream those changes to the running production JVM via the Attach API?
In this talk, we'll demo exactly that using Hazelcast and Hazelcast Jet - but it’s possible to re-use the principles that will be shown using other streaming technologies.
About the speaker

About the event
So your microservice system has been up and running for a while. You know you’ve diligently employed every ounce of your experience and knowledge over time to design a sensible application architecture, with hopefully sensible boundaries.
But time is now throwing new questions your way:
Are my boundaries still sensible?
Have any anti-patterns crept in, have I inadvertently created the dreaded distributed monolith?
This talk explores how network science and graph theory techniques can be applied to help gain insight into, and explore questions about your microservices architecture.

LJC Virtual Meetup: Robin Moffatt's Apache Kafka Series

Join the LJC over the next 3 weeks for a series of Apache Kafka talks by Robin Moffatt. Robin is a Senior Developer Advocate at Confluent, the company founded by the original creators of Apache Kafka, as well as an Oracle ACE Director (Alumnus).
Talk 1: Apache Kafka and ksqlDB in Action: Let’s Build a Streaming Data Pipeline! - Wednesday 29th April at 7pm
Talk 2: From Zero to Hero with Kafka Connect - Wednesday 6th May at 7pm
Talk 3: Introduction to ksqlDB - Wednesday 13th May at 7pm
Apache Kafka and ksqlDB in Action : Let’s Build a Streaming Data Pipeline!
Kafka is a whole lot more than just a message bus! It includes stream processing and integration capabilities, and this talk will be mostly live coding to demonstrate what can be built around it, how to do it - and why to do it.
Have you ever thought that you needed to be a programmer to do stream processing and build streaming data pipelines? Think again! Apache Kafka is a distributed, scalable, and fault-tolerant streaming platform, providing low-latency pub-sub messaging coupled with native storage and stream processing capabilities. Integrating Kafka with RDBMS, NoSQL, and object stores is simple with Kafka Connect, which is part of Apache Kafka. ksqlDB is the source-available SQL streaming engine for Apache Kafka, and makes it possible to build stream processing applications at scale, written using a familiar SQL interface.
In this talk, we’ll explain the architectural reasoning for Apache Kafka and the benefits of real-time integration, and we’ll build a streaming data pipeline using nothing but our bare hands, Kafka Connect, and ksqlDB.
From Zero to Hero with Kafka Connect
Integrating Apache Kafka with other systems in a reliable and scalable way is often a key part of a streaming platform. Fortunately, Apache Kafka includes the Connect API that enables streaming integration both in and out of Kafka. Like any technology, understanding its architecture and deployment patterns is key to successful use, as is knowing where to go looking when things aren’t working.
This talk will discuss the key design concepts within Kafka Connect and the pros and cons of standalone vs distributed deployment modes. We’ll do a live demo of building pipelines with Kafka Connect for streaming data in from databases, and out to targets including Elasticsearch. With some gremlins along the way, we’ll go hands-on in methodically diagnosing and resolving common issues encountered with Kafka Connect. The talk will finish off by discussing more advanced topics including Single Message Transforms, and deployment of Kafka Connect in containers.
Introduction to ksqlDB
You’ve got streams of data that you want to process and store? You’ve got events from which you’d like to derive state or build aggregates? And you want to do all of this in a scalable and fault-tolerant manner? It’s just as well that Kafka and ksqlDB exist!
This talk will be built around a live demonstration of the concepts and capabilities of ksqlDB. We’ll see how you can apply transformations to a stream of events from one Kafka topic to another. We’ll use ksqlDB connectors to bring in data from other systems and use this to join and enrich streams—and we’ll serve the results up directly to an application, without even needing an external data store.

We're back with our 3rd LJC Lunchtime Lightning Talks session.
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. So we don’t yet know what will be on. We will update this when we know.
We will aim to have 4-5 lightning talks followed by a session in the breakout rooms. 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 is an online event starting at 12.30pm BST. Attendees will be sent a link on or before the day of the event.
This event is organised by RecWorks on behalf of the London Java Community.

How to grow the cooperative economy, support and sustain radical technology, and create positive social impact in its locality.
About this Event
In this workshop Polly, who has been developing SPACE4 since it began in 2017, will share some of her top tips. SPACE4 is a work, training and events space that is run by Outlandish Cooperative with support from the wider CoTech community. It aims to grow the cooperative economy, support and sustain radical technology, and create positive social impact in its locality.
In 2019 SPACE4 moved from its original location to a larger space. We have been contracted by Islington Council to operate this space for the next 10 years. We are now building partnerships in order to deliver more, as well as continuing to develop our core programme of public training and events and bespoke support for our community. We're already in discussions about operating new spaces and projects across the UK in collaboration with local partners.
This workshop will build on the SPACE4 case study, and Polly's 10 years of experience working in related fields, to discuss how to procure a building or space, how to fund space-related projects, and tips for developing a cohesive and impactful community. We'll also touch on some aspirations for SPACE4, highlighting examples of inspiring projects and best-practice from around the world.

About the event
We needed to validate our use cases with tests:
That specify the user intents, not the technical details
That are human-readable (but without regex tricks)
That run both end-to-end to verify our infrastructure
And using the domain only to verify our hexagonal architecture
This talk is about how we solved these problems with the DDT approach and how you can apply this technique on your own backend application. A demonstration with live coding will show how to write them and use
it to drive the development.
Who should attend this event?
People interested in clean coding and acceptance testing. The presentation is quite technical but the ideas can be useful not only to developers.
What will people learn?
This talk will teach you a new approach to test your system that can be immediately useful, especially if you are aiming for continuous delivery. The main focus of the talk will be on the idea of Domain Driven Test, where we write an abstract test using Actors on a Stage that will run across multiple implementations. This allows us to use the same tests for both the end-to-end validation and the modelling of our business logic.
This is an online event starting at 7 pm BST. Attendees will be sent a link on or before the day of the event.

LJC Virtual Meetup: Robin Moffatt's Apache Kafka Series
Description changed:

Join the LJC over the next 3 weeks for a series of Apache Kafka talks by Robin Moffatt. Robin is a Senior Developer Advocate at Confluent, the company founded by the original creators of Apache Kafka, as well as an Oracle ACE Director (Alumnus).
Talk 1: Apache Kafka and ksqlDB in Action: Let’s Build a Streaming Data Pipeline! - Wednesday 29th April at 7pm
Talk 2: From Zero to Hero with Kafka Connect - Wednesday 6th May at 7pm
Talk 3: Introduction to ksqlDB - Wednesday 13th May at 7pm
Apache Kafka and ksqlDB in Action : Let’s Build a Streaming Data Pipeline!
Kafka is a whole lot more than just a message bus! It includes stream processing and integration capabilities, and this talk will be mostly live coding to demonstrate what can be built around it, how to do it - and why to do it.
Have you ever thought that you needed to be a programmer to do stream processing and build streaming data pipelines? Think again! Apache Kafka is a distributed, scalable, and fault-tolerant streaming platform, providing low-latency pub-sub messaging coupled with native storage and stream processing capabilities. Integrating Kafka with RDBMS, NoSQL, and object stores is simple with Kafka Connect, which is part of Apache Kafka. ksqlDB is the source-available SQL streaming engine for Apache Kafka, and makes it possible to build stream processing applications at scale, written using a familiar SQL interface.
In this talk, we’ll explain the architectural reasoning for Apache Kafka and the benefits of real-time integration, and we’ll build a streaming data pipeline using nothing but our bare hands, Kafka Connect, and ksqlDB.
From Zero to Hero with Kafka Connect
Integrating Apache Kafka with other systems in a reliable and scalable way is often a key part of a streaming platform. Fortunately, Apache Kafka includes the Connect API that enables streaming integration both in and out of Kafka. Like any technology, understanding its architecture and deployment patterns is key to successful use, as is knowing where to go looking when things aren’t working.
This talk will discuss the key design concepts within Kafka Connect and the pros and cons of standalone vs distributed deployment modes. We’ll do a live demo of building pipelines with Kafka Connect for streaming data in from databases, and out to targets including Elasticsearch. With some gremlins along the way, we’ll go hands-on in methodically diagnosing and resolving common issues encountered with Kafka Connect. The talk will finish off by discussing more advanced topics including Single Message Transforms, and deployment of Kafka Connect in containers.
Introduction to ksqlDB
You’ve got streams of data that you want to process and store? You’ve got events from which you’d like to derive state or build aggregates? And you want to do all of this in a scalable and fault-tolerant manner? It’s just as well that Kafka and ksqlDB exist!
This talk will be built around a live demonstration of the concepts and capabilities of ksqlDB. We’ll see how you can apply transformations to a stream of events from one Kafka topic to another. We’ll use ksqlDB connectors to bring in data from other systems and use this to join and enrich streams—and we’ll serve the results up directly to an application, without even needing an external data store.

LJC Virtual Event: Fantastic Performance and where to find it
Description changed:
***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-virtual-event-fantastic-performance-and-where-to-find-it-tickets-102805558192 ***
This example-driven talk will guide you through concrete approaches to using continuous profilers in a production environment.
Remember the old days - when your software stack was simple to understand and requirements were less demanding? With modern systems distributed microservices talk to each other all the time over the network. Cloud deployments mean a huge variance in the type of hardware that you deploy to. Rapid iteration and deployment cycles result in rapidly changing workloads that invalidate performance tests before they’re written. Globalised, 24/7 uptimes mean that functional or performance outages aren’t acceptable at any point in time.
These changes have helped businesses get their product out to market much more rapidly but they often make it harder for developers to find and fix performance problems or to improve the efficiency of their systems.
From attending this talk you’ll understand:
Common profiling visualisations and reports
How to use profilers to solve performance problems
The benefits of continuous, exploratory, profiling.
How to improve scalability, have happier customers and reduce infrastructure costs

Joint Virtual Meetup with the London CTOs: Rethinking Cloud Migrations
Description changed:

Join our friends at the London CTOs for their upcoming talk on Rethinking Cloud Migrations with Omar Bashir.
Benefits of migrating a firm’s technology estate to the cloud are well known. These include cost reduction, operational efficiency, scalability and technological agility leading to shorter time to market and higher operating margins. But these benefits are only realised once such migrations also involve transformation in the way technology is developed and delivered.
Decisions ranging from product management to engineering and operations affect the outcome of these initiatives. An outcome driven approach to cloud migration and transformation minimises associated risks.
This talk discusses how deviating from such an approach leads to failed cloud migrations.

Microprocessors have evolved over decades to eke out performance from existing code. But the microarchitecture of the CPU leaks into the assumptions of a flat memory model, with the result that equivalent code can run significantly faster by working with, rather than fighting against, the microarchitecture of the CPU.
In this talk, Alex Blewitt will present the microarchitecture of modern CPUs, showing how misaligned data can cause cache line false sharing, how branch prediction works and when it fails, how to read CPU specific performance monitoring counters and use that in conjunction with tools like perf and toplev to discover where bottlenecks in CPU heavy code live. We’ll use these facts to revisit performance advice on general code patterns and the things to look out for in executing systems. The talk will be language agnostic, although it will be based on the Linux/x86_64 architecture.
Who should attend this event?
Developers who want to understand how (Intel) x86 processors work and who want to optimise software for greater performance.
What will people learn?
Attendees will learn how to use various low level performance tools on Linux for measuring where performance lies.
About our speaker
Alex Blewitt has been working with Java since its first release, and has worked on JVM projects at Goldman Sachs and Credit Suisse, where he was the JCP representative until 2016. He co-founded the Docklands.LJC and has spoken about Java and performance at several conferences, and writes for InfoQ about Java and JVM topics.
Before moving to Santander in 2020 he worked at Apple on Swift, and has authored books in Swift and Eclipse plugin development.

New Relic recently published the results of their Java ecosystem research based on data sent to them by their customer's JVMs. Ben Evans, Java Champion and Principal Engineer at New Relic (as well as long-time LJC alumnus) joins us remotely from Barcelona for a lightning talk and Q&A about the results and what they tell us about Java usage in 2020.
Evolving Compilation with Graal
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 explore practical examples and the subsystems that are involved in interpreting, compiling and executing a simple Hello World Application. We will dive into JIT compilation and the arrival of the JVM Compiler Interface (JVMCI) to explore how optimisations are applied to boost the performance of our application. We will discuss HotSpot, explore Graal and the JVM ecosystem to discover performance benefits of a platform 25 years in the making.

Remote working for teams - how to make it work for real
For whatever reason you need to work apart from your colleagues. This time though it's a bigger challenge: this time it has to be for longer than the odd day. Gone is working from home to get your head down to write code. This may go on for sometime so now you and your team need to work effectively together using whatever digital technologies you can lay hands on. It’s a tall order.
In the old days (like last week) we’d have organised a meetup and had a few experienced folk explain how to rise to the challenge. Obviously that’s not really advisable so in the spirit of the moment let’s try something a little different.
We are running a virtual roundtable with everyone remotely connected: a moderator to keep things focused, a panel of experienced (or at least opinionated) advisors and an audience that can interact with the panellists. Be part of an interesting experiment and hear good advice about how to work remotely in teams.
Topics will include:
Thoughts on the right tech to use
How digital meetings work (or don’t) compared to face to face
How to keep sane when no one can see what you’re wearing
Can pair-programming work remotely?
Communicating with others when you can’t read body language (how to tell if someone is upset or happy)
How to get the team cohesive
and finally....
How to not work too hard when at home.

Digital Workplace Summit is the leading event to address the digital workplace revolution, boost employee engagement and power the future of work – offering unparalleled access to decision makers, visionaries, influencers and disruptors from the world of enterprise and tech.
Design plays a key role in our every day lives. Whether we explicitly notice it or not, so much around us is consciously designed - our buildings and cities, the tools and services we use, books, images, websites and images. Yet when capitalism encroaches on all elements of life, graphic designers are forced into advertising, and architects have little choice but to design banks and shopping centres. As we face global political insecurity and environmental catastrophe, what role can designers play in building strong social movements?
This event will bring together designers who are interested in applying their skills to social issues and building social movements. Join us to hear their thoughts, and discuss the issues at stake. We'll be hearing from:
Gemma Copeland
Gemma is an interdependent digital designer. She is a member of Common Knowledge, a worker cooperative that designs digital tools for grassroots activists. She is also part of the new Designers + Cultural Workers branch of United Voices of the World. Gemma will discuss the agency that designers have in building alternative social and political structures, given that design is inherently an imaginative and relational practice.
Autonomous Design Group
Autonomous Design Group is an independent collective of designers,
artists and creatives opposed to capitalism and authoritarianism. They
believe that the aesthetic is of vital importance in the terrain of
political struggle; all their designs are available open-source and they
design for a variety of groups www.weareadg.org. They will give a brief historical introduction to brief history political design collectives
(Atelier Populaire, Grapus, DSG) and discuss their work and motivations.
Robbie Blundell
Robbie Blundell works as an interdependent graphic designer.
Through this he has recently been developing and maintaining an assemblage of aesthetics, cooperatives, technologies, identities, communities, politics, friends and cultures. He is a member of Evening Class and previously co-produced Strike magazine.
Julian Siravo & Francesca Farruggia
Julian & Francesca are part of Autonomy_Urban and has been developing a series of de-commodified infrastructures for work, including co-working facilities, SME logistics support services and an infrastructure for the future of ageing and social care. He’ll be presenting the latter of the three, Long Term Care Centres looking at how we can build a home for community care a cooperative nursing.
The Venue/Organiser
SPACE4 is a work and events space that aims to bring together people and organisations to use digital technology for social good and activism. We particularly work with cooperatives and non-hierarchical organisations, and is part of CoTech, the UKs network of digital co-operatives.

On Monday 2nd March we'll have an OpenStreetMap pub meet-up at the Parcel Yard Pub in Kings Cross station from 6:30. Join us for friendly social beers and chit chat on the subject of OpenStreetMap (contributing/using experienced/beginners, whatever interests you in and around OpenStreetMap!)
The pub is quite big, but hidden away at the back of the main station curvy roofed bit, up some steps. (1st floor. We won't be on the 2nd floor posh dining area) We'll try to get a table, but at first we may have to loiter near the bar. If we are organised we'll have OSM polo shirts or hi-vis jackets on show. If you don't know anyone it'll be a bit easier to find us if you show up a bit late. ...not too late though. We'll probably end up going to eat burritos on the station balcony later on.
Set yourself as attending on here! (if you can figure out how to). Sign-up not actually required. It is just a pub after all. You can expect between 5 and 10 people attending.

GraphQL in Java - Lightning Talk
Details TBC
Java Flight Recorder and How It Can Help You
JFR is finally hitting the mainstream. This talk explains what JFR is, where it came from and why it is only really now that all Java developers can start to use it to best effect.
We'll talk about the open-source Java 11 edition of JFR (and JMC) but will also touch on the Java 8 backport. Finally, we'll talk about Java 14 JFR Event Streaming and why this is so significant.
