Do you even handle effects?

Abstract

Scala’s effect systems have come a long way from Monix and Scalaz, to Cats Effect, ZIO, and now Ox and Kyo. The debate between monadic and direct styles is at its peak or maybe, it doesn’t have to be a debate at all.

YAES (Yet Another Effect System) introduces a new approach that lets you combine both styles seamlessly. In this session, we’ll explore how effect systems work, how Scala libraries handle them, and how Scala 3’s context functions enable building a direct-style effect system without losing the power of monadic composition. Join us to discover how you can write expressive, type-safe code while choosing the style that fits you best.

Blazing fast startup time on JVM with limited effort

Abstract

A fast startup time can bring big cost saving on cloud, increased reliability with traffic peaks and avoid over provisioning of resources. We will deep dive into what the JVM is doing at startup and explore three different options to improve the startup time with only a limited development effort.

Zig What, how and why

Abstract

This talk introduces Zig, a relatively young programming language with great future prospects. Zig is a low-level language with a minimalist philosophy, ideal for applications that require precise control of latency and resources. It combines a minimal syntax similar to Go with manual memory management and compilation checks like Rust, but with shorter compilation times. Key features include code execution during compilation, interoperability with C libraries, and high portability. The talk explores the Zig language and its ecosystem for developing modern applications.

UX principles for developers

Abstract

Il talk offre una panoramica su alcuni principi fondamentali dell’User Experience (UX), e sul valore di metterli a fattor comune tra designer e developers. Attraverso esempi pratici e consigli applicabili, verranno mostrati i principi che sono dietro a molte scelte progettuali che abilitano un approccio collaborativo tra design e sviluppo in modo da accrescere la sinergia di un team e migliorare il valore di un prodotto.

JVM Ergonomics for Software Engineers

Abstract

Mollie doesn’t have a Java platform team, so software engineers needed to learn how to deal with some basic JVM performance tuning, discovering JVM Ergonomics along the way.

We’ll briefly touch upon a few different aspects of the JVM and how they are managed by default:

Memory allocation
Garbage collection
Active processor count We’ll go through a real use case that we had at Mollie, the problem we faced, and how some basic knowledge of JVM Ergonomics helped us solve the issue.

Redis come Vector Database

Abstract

Redis è famoso per essere un database in tempo reale estremamente versatile: funziona benissimo come cache, per conservare sessioni utente o token di autenticazione, gestire inventari, dati geografici, JSON document store e persino come base per il machine learning. Ma non tutti sanno che Redis è anche un vector database, anzi è il Vector database alla base di Chat-GPT sin dal principio. In questo talk approfondiremo cosa si intende per vettore e analizzeremo le caratteristiche che una vector database deve avere per poter interagire con uno spazio vettoriale.
