LJC Virtual Meetup: 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-110242395974?aff=meetup*** We're back with our 7th 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. We will aim to have a maximum of 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 event is organised by RecWorks on behalf of the London Java Community. You can see our latest jobs here: https://recworks.co.uk/java-developer-jobs-london/.

LJC Virtual Meetup: Bootiful Kotlin

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-virtual-event-bootiful-kotlin-tickets-112484117022?aff=meetup*** Spring Boot, the convention-over-configuration centric framework from the Spring team at Pivotal, marries Spring's flexibility with conventional, common sense defaults to make application development on the JVM not just fly, but pleasant! Spring Boot aims to make address the common functional and non-functional requirements that gate quickly moving to production. The framework is as clean as it gets, wouldn't it be nice if the language matched its elegance? Kotlin, the productivity-focused language from our friends at JetBrains, takes up the slack to make the experience leaner, cleaner and even more pleasant! The Spring and Kotlin teams have worked hard to make sure that Kotlin and Spring Boot are a first-class experience for all developers trying to get to production, faster and safer. Come for the Spring and stay for the Bootiful Kotlin. About the speaker Josh Long is the Spring Developer Advocate at Pivotal. Josh is a Java Champion, author of 6 books (including O'Reilly's Cloud Native Java: Designing Resilient Systems with Spring Boot, Spring Cloud, and Cloud Foundry and the upcoming Reactive Spring) and numerous best-selling video trainings (including Building Microservices with Spring Boot Livelessons with Spring Boot co-founder Phil Webb), and an open-source contributor (Spring Boot, Spring Integration, Spring Cloud, Activiti and Vaadin), a podcaster (A Bootiful Podcast) and a screencaster.

LJC Virtual Meetup: How developers are the new security rockstars

***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-how-developers-are-the-new-security-rockstars-tickets-112499826008?aff=meetup *** Waterfall, Agile, DevOps... it seems that every few years, a new methodology is born for optimum software creation within an organization. While these processes all have their strengths and weaknesses, the streamlining (and, er, previously absent red tape) they bring can feel like somewhat of a hindrance to the main goal of the developer: BUILDING KICK-ASS FEATURES. Join this webinar to learn tactical methods on building a successful devsec strategy. We’ll cover: · The power of shifting and starting left - what this means for developers · Creating a secure software development lifecycle · Top training programs to help developers master security practices and vulnerabilities trends About the speaker Stefania Chaplin is EMEA's Solution Architect at Secure Code Warrior. Her experience within Cybersecurity, DevSecOps and OSS governance means she's helped countless customers understand and implement security throughout their SDLC. As a python developer at heart, Stefania is always itching to improve efficiency wherever she goes by writing scripts to automate processes. Stefania is passionate about speaking about DevSecOps and cybersecurity, and has spoken at many conferences and meetups across Europe including; JavaZone in Norway, JFokus in Sweden and Cloud Expo, Women of Silicon Roundabout and Women in DevOps in London. Most recently, Stefania has been speaking at many virtual events on publications such as DZone and on the Secure Code Warrior Brighttalk. This is an online event starting at 7 pm BST.

LJC Virtual Meetup: Interacting with Ethereum Blockchains with Groovy and web3j

***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-meetup-interacting-with-ethereum-blockchains-with-groovy-and-web3j-tickets-112789305850?aff=meetup *** Ethereum is currently one of the most exciting technologies in the Blockchain domain, providing us with a turing-complete distributed “world-computer” and a “rich statefulness”. But how do you actually interact with such a system from within your applications and your code? Is it like using a database, a web service, the cloud? The answer is probably yes and no… In this talk, we want to have a look under the hood and see some real code examples of how to interact with Ethereum. We will use web3j, a Java implementation of the quasi-standard Javascript Etheuerem client library web3 and we will use it not only with Java but with Groovy to get the flexibility and ease of a scripting language onto the JVM. And we will get sciency and use Groovy to get some data science work done with data we extract from Ethereum, demonstrating that Python and R aren’t the answer for everything. About the speaker Kevin Wittek is a Testcontainers co-maintainer and Testcontainers-Spock author, in love with FLOSS. He received the Oracle Groundbreaker Ambassador award for his contributions to the Open Source community. He is a Software Craftsman and testing fan. Plays the electric guitar and is a musician in his second life. Found his own company during his university years, developing mobile apps and client-server applications, which introduced him to Grails and the Groovy ecosystem. Fell in love with TDD because of Spock. After many years working in the industry as an engineer, Kevin is now doing his PhD at the Institute for Internet Security and is leading a research team in the field of blockchain technology. This is an online event starting at 12.30 pm BST. This event is organised by RecWorks on behalf of the London Java Community.
