LJC Meet-up at Elastic

The LJC is delighted to continue our new series of events, aimed at giving all Community members an opportunity to present at an LJC meet-up.

If you have an interesting topic to share, these events are for you. You don’t have to be an experienced speaker - we want to hear your story and offer you a friendly, informal platform to practise and improve your presentations.

For attendees we want this to be a meeting place, where you can talk and network with other technologists in London.

If you’d like to speak at a future event, please submit your talk and bio details here: https://sessionize.com/ljc/

Huge thanks to our friends at Elastic for hosting this event and supporting our Community.

Speaker One:

Carly Richmond - Developer Advocate & Manager @ Elastic

Talk: How to Destroy a Software Engineer

@Retaining Software Developers is a significant challenge for teams. According to the Infragistics Reveal Survey, 37.5% of respondents expected difficulty in finding developers in 2023. To retain talent and keep DevOps engineers happy, we need to know how to make them unhappy.

Join me as I discuss antipatterns in management, development, testing and monitoring patterns that can stop you retaining awesome software engineers.

Outline

• I’ll cover:- Alert volume evaluation, and how we alert bombardment leads to burnout and alert fatigue. I’ll also cover best practices for on-call rotation and BYOD usage to stop engineer burnout even when they’re not on call.
• SLO and metric comparison across teams, and how comparing team metrics rather than improving metrics such as DORA over time for a single team breeds animosity and demoralises engineers.
• Code reviews with jerkish or unhelpful comments, and the difference between radical candour through constructive feedback and pulling people down.
• Tool overload, and how selecting a common toolbox reduces the need for context switching.
• Flaky or poor testing, and how it builds mistrust and apathy in platform quality.
• Constant work items and a lack of learning time, and how a lack of training opportunities and space to grow leaves engineers feeling stuck.
• Lack of support for conference attendance and speaking, and how community connections help engineers grow and learn.

Speaker Two:

Alisher Alimov - Software Engineer at NVIDIA

Talk: Transition to a reactive architecture

The presentation is focused on practical aspects of transition to reactive architecture. It discusses the problems of processing large volumes of requests and managing distributed services. The presentation emphasizes moving from traditional blocking operations to non-blocking, asynchronous processes to improve scalability, fault tolerance, and performance.

Key points include:

• Introduction to Reactive Architecture: Understanding the need for a scalable and fault-tolerant architecture that efficiently handles client requests while minimizing errors.
• Reactive Architecture Solutions: Discusses how the principles of reactive architecture, including non-blocking I/O, event-driven programming, and microservices, address these challenges, resulting in more efficient resource utilization, reduced latency, and improved overall system performance.
• Practical Applications: Examples of reactive architecture implementations in real-world scenarios, especially in environments requiring high parallelism and low latency processing.
• Challenges in transition to reactive architecture

The goal of the presentation is to educate the audience on the benefits of moving from blocking operations to a more efficient, reactive approach, ultimately leading to more responsive and scalable systems.

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

The London Java Community is sponsored by Hazelcast, Neo4j, Redis, and Discover
