Online Tech Conferences Spring 2022 | Backend

Description:
The coronavirus pandemic has taught us developers two things: 1) all online systems will fail eventually and 2) they will fail in unpredictable ways. But have no fear, resilience engineering is here! Building and maintaining event-driven, highly scalable and quickly adaptable systems are a pain in the neck. Resilience engineering embraces this complexity and helps you manage it. In this talk, I will explain what resilience engineering is, why every software person should know about it and how you can start practicing it.

Description:
Let's dive a bit into the beautiful and symmetric structure of a type like Result or Either, and see how to handle failure in a more functional-programming-inspired way. We explore topics such as what 'flatMap' means for these types, or how right and wrong are just two symmetric ways to look at the operations.

Description:
Serverless is much more than simple HTTP triggered functions. You can run containers and whole apps serverlessly, group functions behind an API gateway, coordinate services with a central orchestrator or let them communicate indirectly via events. Serverless services can be scheduled or made more resilient with task queues. You can even combine serverless with serverful services. In this talk, we’ll look at the serverless landscape beyond simple functions.

Description:
Serverless has changed the way we build software for the better. But it’s also a paradigm shift that challenges many of our pre-existing practices and habits, like how we test our code and how we monitor their health. In this session, Yan Cui will share many of the lessons he has learned from running serverless in production over the last five years. Including tips on testing, observability, and how to keep your AWS cost in check.

Description:
Hyperledger Fabric is the most popular framework for developing blockchain applications for the enterprise. This session will present its unique characteristics, some of the use cases it is designed for, and discuss the latest developments and what's yet to come. Attendees will leave with the information they need to get started developing their own applications with Fabric.

Description:
Whether you are a developer, operator, or other kind of engineer, you will need to secure your applications, platforms, continuous integration frameworks, and data. Rosemary Wang provides a list of practices and patterns to build minimum secure applications, infrastructure, and automation. Knowing the basics will help you build security into your systems instead of adding them after deployment. From access control considerations to encryption, you’ll learn and teach others to better secure systems as they scale to support applications and users.

Description:
AppSync lets you build scalable and robust GraphQL API without having to worry about infrastructure. In this session, AWS Serverless Hero Yan Cui shares his personal experience of running AppSync in production - the good, the bad and some tips for dealing with common challenges such as testing VTL templates and overcoming the 500 CloudFormation resources limit.

Description:
Todos sabemos añadir un loading="lazy"a nuestras imágenes, pero ¿Y si te dijese que la tipografía que usas puede estar hundiendo la velocidad de tu web? Crees que la API tan ordenada no podría dar fallos a la hora de acceder, pero sorpresa, no es así y nuestro usuario deja de visitar la app porque el contenido no carga. Hay detalles desde lo más aparentemente insignificante hasta archivos pesados en frontend y backend que pueden hacer que la performance de nuestra web se hunda, y con ello el rendimiento y su número de visitas. ¡Pero no te alarmes querido padawan, para eso hemos venido!

Description:
When you hear "decision-maker", it's natural to think, "C-suite", or "executive". But these days, we're all decision-makers. Restaurant owners, bloggers, big-box shoppers, diners - we all have important decisions to make and need instant actionable insights. In order to provide these insights to end-users like us, businesses need access to fast, fresh analytics. In this talk, we'll show how to build a real-time analytics dashboard using the Apache Kafka messaging platform, Apache Pinot OLAP database, and Streamlit application framework. There will be lots of graphs and other visualisations!

Description:
Embedded mobile data persistence has always been a complicated topic. For long, SQLite has been the only viable embedded database. We offer an alternative that's easier to learn, simpler to use, more flexible, and more in line with mobile application development architectures. In this talk, we will introduce a new data persistence library for Kotlin/Multiplatform: an embedded NoSQL database with common Kotlin API available for multiple Kotlin targets such as Android through Kotlin/JVM and iOS through Kotlin/Native. First, we will explore its data and ORM API, showing how can Kotlin data objec

Description:
Functional programming is gaining popularity and partly because of this people have been switching to Kotlin. Although it fits the paradigm better than Java, there is still quite a bit missing to unleash the full power of FP. Arrow is here to fill in the missing bits with things like new datatypes, e.g. Try, Either, and Optics. Arrow is the most popular functional programming library for Kotlin. In this talk we will go through what problems Arrow can solve for you and how it can help you with your everyday programming.

Description:
At TrueLayer, we leverage gRPC to have strongly-typed contracts between our microservices. In this talk, we will showcase the main approaches of gRPC load balancing and why we decided to adopt client load balancing for our rust microservices. We will also introduce ginepro – an open-source library we built to provide service discovery to perform client-side look-aside gRPC load balancing.

Description:
Putting the Q in Computer; Quantum Technology implications for Cybersecurity By Esmée Snoey Kiewit, CEO 77 Cybersecurity For a brief 30 minute talk, I propose a 3-step plan. To start with the Quantum Mechanics and Physics principles that underly the subjects that make Quantum Computing Technologiesn work, and if time allows the experiments that proved them. Part 2 entails what Quantum Technologies will change in hardware and algorthimes. In part 3 I will talk about the Quantum implications on cybersecurity, with a focus on encryption.
