As programmers, we rarely deal with the processing of geographic data, yet it is undoubtedly a fascinating issue with many tools designed to troubleshoot problems and automate geospatial analysis. In this presentation, you will learn the basics of cartography and the existing approaches to storing and processing spatial data. The main emphasis will be on using DBMS as a tool for working with geoinformation; we will also demonstrate the capabilities of the PostgreSQL extension called PostGIS. As a practical example, a test application will be used to organize a notification system for small uncrewed aerial vehicle flights.

At first glance, functional programming paradigms may seem complex and unintuitive — a lot of definitions, mathematical concepts, and a different approach to designing your code architecture. But is it worth our time and struggle to learn? Is it really that difficult? And the most important question of all, is it actually beneficial to use FP? During this presentation, Joanna will answer all these questions and more. We will be starting off with basic FP concept, focusing on code performance and optimization, and finally we will compare approaches to creating, debugging, and refactoring imperative vs. declarative functional code.

Many of us have experienced working on projects with established processes, gradually introducing small suggestions and improvements. But what do you do when the project is just starting? What do you do when the customer expects out-of-the-box solutions ranging from testing techniques to project tools of choice? In this presentation, Maksim Marasanov will discuss how to build a process from scratch and justify your choices to clients using an example from a real engagement. If you're involved in testing processes or work with clients without deep QA knowledge, this talk is for you!
