[GRCCP] - Athens C++ Meetup

We are happy to announce our third meetup that will be held physically at XM, in Athens.

We will have two talks, one about how to learn C++ as a beginner and another about the Boost.Geometry library. After the talks there will be time for Q&A, food and networking.

📍 Location 📍

• Michalakopoulou 80 street, 1st floor.
• Attendees should register with their meetup name at the entrance

⏰ Date & Time ⏰

• 18 of September 2025, 19:00

🔗 Prerequisites & Target audience 🔗

The talks are aimed at developers who are interested in C++.

🇬🇷 Language 🇬🇧

🎤 About the talks 🎤

The long road to studying C++

• Οργάνωση χρόνου μελέτης, μέρα/εβδομάδα/μήνα, για εργαζόμενους.
• Καθορισμός (βραχυπρόθεσμων-μακροπρόθεσμων) στόχων.
• Ύπνος, υγεία και άλλα θέματα ευεξίας.
• Τα 4 στάδια στην εξέλιξη και την εκμάθηση της γλώσσας.
• Προτεινόμενα βιβλία προς μελέτη, και με ποιά σειρά.
• Πώς η Τεχνητή νοημοσύνη επηρρεάζει την μελέτη.

Ο Γιώργος Δούμας είναι πτυχιούχος φυσικός, που άρχισε να ασχολείται από μόνος του με Linux και προγραμματισμό σε bash, C, C++, Python.
Αφού εργάστηκε αρκετά χρόνια στην τεχνική υποστήριξη, και μετά ως Linux administrator, κατάφερε να εισέλθει στον χώρο της ανάπτυξης λογισμικού, και θα μας μεταφέρει κάτι απο την εμπειρία του ως αυτόνομος μελετητής/μαθητής της C++.

Boost.Geometry: A C++ library for geometric computations

Boost.Geometry is a C++ library defining concepts, primitives and algorithms for solving geometry problems. It contains a dimension-agnostic, coordinate-system-agnostic and scalable kernel, on top of which algorithms are built: area, distance, convex hull, intersection, within, simplify, transform etc.
The library contains instantiable geometry classes, but library users can also use their own legacy geometry types. It also contains spatial index allowing to perform spatial and knn queries on a collection of geometries.
In this talk we will introduce Boost.Geometry focusing on mapping and GIS. The presentation will highlight recent developments in the library and conclude with a roadmap of the future work in Boost.Geometry.
