Day 1

This talk explores the similarities and differences in how business organisations engage with Open Source. It highlights the growing relevance of Open Source for the digital economy and digital sovereignty, and examines typical business models and organisational models for Open Source communities, including how both can effectively collaborate with the other.

This all is essential to understand how long lasting and profitable business can be generated out of Open Source activities and along this how new risks with it can be addressed.

According to **NASSCOM**, India produces almost half a million software developers annually.
However, very few of these gifted people are aware of LibreOffice—much less its open-source status and contribution opportunities.
As a result, there is a paradox: **great potential but very little engagement**.

The sustainability of Free and Open Source Software (FOSS) projects depends on the regeneration of contributors across generations. As priorities shift with age, many senior contributors reduce their involvement, leaving gaps in community activities. This highlights the importance of empowering the younger generation to take on active roles in project development and community management. Their participation brings faster innovation, fresh perspectives, and awareness of new technological trends that ensure projects remain relevant.

Many people assume that contributing to an open-source project like LibreOffice is always fun and exciting. The reality, however, is often more complicated. Contribution can be frustrating, slow, and sometimes even discouraging—yet it remains deeply rewarding. In this talk, I will share my personal experience as a long-term contributor: the challenges I have faced, the moments of doubt, and the real value that keeps me engaged.

This talk will give a brief technical overview of typical modern text rendering approaches. The overview will trace the complete text graphics stack, starting from the elementary concepts of font glyph rasterization, through the hardware graphics processing unit, to pixels on the screen. Special attention will be given to engineering decisions that were made to improve the visual quality of Latin text, at the expense of use cases involving higher glyph counts, such as most CTL and CJK writing systems.

This talk introduces our(OSS Integral Institute Co., Ltd.) experience of vibe-debugging LibreOffice using Cursor AI Editor/Visual Studio Code Copilot/Gemini CLI. We use LLMs and AI agents to locate the logic that contains the bug and help developing potential patches to properly fix the bug.

We'll also share our discovery on:
