"Laravel Tips & Tricks - 7 Steps to Dramatically Improve Performance", Yehor ...

Imagine that you've been given an old project, a Food Delivery app, with the backend written in Laravel 8 and PHP 8.0. The web and mobile interfaces communicate with the backend through an API, but it's currently performing poorly with an average response time of 600ms. The product owner has requested you to optimize the performance and wonders if it's possible to reduce it by a factor of 10. What would you do? Topics to be Covered: Nginx Cache Rememberable package Redis Cache Queues: Redis/SQS Horizon Octane: Swoole / Roadrunner Upgrading PHP and Laravel While you may be familiar with most of these points and possibly already using them, the focus will be on ensuring that you're using them correctly and effectively. In a real-world example, I will demonstrate how we managed to reduce average response times by 10 times. We'll explore what's hidden under Laravel's package magic and discuss ways to mitigate the negative impact on project performance. By the end of this performance optimization session, you will not only have improved your performance but also gained a deeper understanding of how to utilize the Laravel framework more efficiently.

"NATO Hackathon Winner: AI-Powered Drug Search", Taras Kloba

This is a session that details how PostgreSQL's features and Azure AI Services can be effectively used to significantly enhance the search functionality in any application. In this session, we'll share insights on how we used PostgreSQL to facilitate precise searches across multiple fields in our mobile application. The techniques include using LIKE and ILIKE operators and integrating a trigram-based search to handle potential misspellings, thereby increasing the search accuracy. We'll also discuss how the azure_ai extension on PostgreSQL databases in Azure and Azure AI Services were utilized to create vectors from user input, a feature beneficial when users wish to find specific items based on text prompts. While our application's case study involves a drug search, the techniques and principles shared in this session can be adapted to improve search functionality in a wide range of applications. Join us to learn how PostgreSQL and Azure AI can be harnessed to enhance your application's search capability.

Direct losses from downtime in 1 minute = $5-$10 thousand dollars. Reputation is priceless. As part of the talk, we will consider the architectural strategies necessary for the development of highly loaded fintech solutions. We will focus on using queues and streaming to efficiently work and manage large amounts of data in real-time and to minimize latency. We will focus special attention on the architectural patterns used in the design of the fintech system, microservices and event-driven architecture, which ensure scalability, fault tolerance, and consistency of the entire system.

"Impact of front-end architecture on development cost", Viktor Turskyi

I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Python engineers are introduced to the transformative potential of Large Language Models (LLMs) in the realm of advanced data analysis and the application of Semantic Kernel techniques. We will talk about how LLMs like ChatGPT can be integrated into Python environments to automate data processing, enhance predictive modeling, and unlock deeper insights from complex datasets. The session will delve into practical strategies for embedding Semantic Kernel methods within Python projects, illustrating how these advanced techniques can refine the accuracy of machine learning models by embedding domain-specific knowledge directly into the analysis process. Attendees will leave with a clear roadmap for leveraging the combined power of LLMs and Semantic Kernels, equipped with actionable knowledge to drive innovation in their data analysis projects and beyond, marking a significant leap forward in the evolution of Python engineering practices.

"Subclassing and Composition – A Pythonic Tour of Trade-Offs", Hynek Schlawack

Ever seen a code base where understanding a simple method meant jumping through tangled class hierarchies? We all have! And while "Favor composition over inheritance!" is almost as old as object-oriented programming, strictly avoiding all types of subclassing leads to verbose, un-Pythonic code. So, what to do? The discussion on composition vs. inheritance is so frustrating because far-reaching design decisions like this can only be made with the ecosystem in mind – and because there's more than one type of subclassing! Let's take a dogma-free stroll through the types of subclassing through a Pythonic lens and untangle some patterns and trade-offs together. By the end, you'll be more confident in deciding when subclassing will make your code more Pythonic and when composition will improve its clarity.
