Prav - reclaiming choice of service providers in messaging (Main track)
- Ravi Dwivedi
15:45 - 16:15
[Prav](https://prav.app) is a [Free Software](https://codeberg.org/prav) app for encrypted messages, files, and audio/video calls. It is inspired by the [Quicksy](https://quicksy.im) app. This talk will focus on the importance of federated messaging. An example of federated communication is phone calls which allow you to talk to any user using a SIM card regardless of which provider they use. As an example, Airtel users can make calls to Vodafone users and vice versa. However, popular messaging apps (WhatsApp, Telegram) only allow you to talk to users using the same app. When WhatsApp changed its privacy policy in 2021 to share its data with Facebook, a lot of users didn't like this move. But the only options users have for such a service is either to uninstall the app or agree to the terms they dislike. The first choice — to uninstall the app — comes at a high cost, as the users lose all their contacts and ability to connect with them. On the other hand, Prav allows you to talk to all the users on the same network (known as XMPP) even if they use other apps like Quicksy, [Monocles Chat](https://xmpp.org/software/monocles-chat/), [Kaidan](https://www.kaidan.im/), [Dino](https://dino.im/), [Monal](https://monal-im.org/), and many more. This gives users choice of service providers and more control over their messaging platform. If Prav makes a decision in the future that you disagree with, you can switch to any other XMPP provider while still be able to connect with your contacts. It is similar to how people change their SIM provider and still be able to connect with their contacts.
16:15 Learnings from creating an input method for KDE - Subin Siby
Learnings from creating an input method for KDE (Main track)
- Subin Siby
16:15 - 16:45
I wanted an input tool to easily write my mother tongue Malayalam (about 37 million speakers around the world) on Ubuntu (KDE + i3), and I came across the FOSS project called Varnam: https://varnamproject.com/ which supported many Indian languages. It was difficult to set it up for me at the time, was 17 years old. It had to be compiled, the docs were lacking and like that reddit meme, “where the heck is the binary” was a question I ended up using it from 2017, later contacting the maintainer, taking up maintainership, and then at the time of pandemic rewrote it from C to Go and later worked on how to make it as easy as possible to use for the end user. There are ten thousands of Ubuntu/Debian users in Kerala (mostly school students), so making the installation first class on Debian was the utmost priority. This talk will be about the learnings of this project from the beginning to 2025 now: input methods (ibus, fcitx), wayland, packaging, bash installer etc. etc from a product perspective that makes it super easy for the end user. Varnam library recently got packaged into Debian thanks to Guido Gunther: https://packages.debian.org/testing/libs/libgovarnam1 and is now used in GNOME Phosh’s keyboard to type Indic languages. Source code: https://github.com/varnamproject/govarnam A talk on the rewrite of Varnam was part of DebConf21: https://debconf21.debconf.org/talks/21-govarnam-a-new-intelligent-input-method-for-indian-languages-in-desktop-mobile/

Workshop: Build Your First QML Interface ! (Main track)
- Aakarsh MJ (KDE)
10:25 - 11:30
This will be a hands-on workshop. I ran this last year and I will be bringing it back with some improvements. We'll be building a couple of simple QML interfaces together, step-by-step. You'll get to follow along and try it out yourself. For the best experience, having VirtualBox installed is helpful. I'll provide a VirtualBox image so you can work locally, which really speeds things up. But don't worry if you don't have it, We'll also use an online QML compiler, so everyone can participate. This lets you play around locally, which makes things a lot smoother but rest assure if you don't have it installed we will be making use of online compiler so you can try things out nicely!

12:00 - 12:30
Windows 10 security updates end on 14 October 2025 [0], which is KDE's 29th birthday and also, ironically, International E-Waste Day [1] (you cannot make these things up!). Hundreds of millions of functioning devices [2] will become e-waste, disposed in large part in countries in the Global South, including India. Moreover, this means manufacturing and transporting new ones, which is perhaps the biggest waste of all: hardware production alone can account for over 75% of a device's CO2 emissions over its lifespan. Free Software is a solution, today! We have an opportunity to coordinate a global, unified Free Software campaign over the next 6 months to raise awareness about the environmental harm of software-driven hardware obsolescence, while upgrading users from Windows 10 to GNU/Linux directly to keep those devices in use and out of the landfill. Let's think big and act boldly! In this talk I will engage attendees from KDE India and the Indian Free Software movement to join the growing "End Of 10" campaign to make Windows 10 the last version of Windows end users ever use.

In today’s digital age, the environmental impact of software is a critical yet often ignored issue. The KDE Eco project tackles this challenge head-on by championing sustainable software development practices within the KDE Community and beyond. As a Season of KDE mentee this year, I contributed to the KDE Eco Remote Eco Lab project, creating comprehensive written and video documentation to support its mission of reducing the ecological footprint of technology. In this talk, I will introduce the KDE Eco project and its innovative approach to sustainability, showcasing how it integrates eco-friendly practices into software development. Drawing from my hands-on experience, I’ll highlight the importance of sustainable software and how KDE is paving the way for a greener future in open-source technology. Beyond promoting KDE Eco, I aim to inspire and guide newcomers to the KDE Community. I’ll share my journey as a mentee, offering practical insights into how students and beginners can get involved through mentorship programs like Season of KDE and Google Summer of Code. Attendees will leave with a clear roadmap for contributing to KDE, from writing their first patch to becoming lifelong open-source contributors. Join me to explore how KDE Eco is transforming software development and discover how you can play a role in building a sustainable future while growing your skills in the vibrant KDE Community.

16:45 - 17:15
Most Free Software projects don’t always have big-money backing, but they still need to distribute massive amounts of software binaries and data. That’s where download mirrors come in—they take the load off primary servers, improve availability, and speed up downloads, especially in different parts of the world. In this talk, we’ll dive into the why, what, and how of setting up a Free Software mirror. You'll gain insight on what happens when you click download on KDE ecosystem sites like krita.org/kdenlive.org/labplot.org etc, how your deb/rpm/appimage/exe/dmg are served from servers near you. I’ve been running mirrors in India [1][2] and Germany [3] for a while now, and I’ll share my experiences [4] — the good, the bad, and the unexpected (hint - last year my mirror nodes pushed 1 PB+ of mirror traffic). All with nginx + rsync + cron and you can do it too (we still don't have a local KDE application data mirror [5]) :) We’ll also take a look at KDE mirror traffic from India [6] to see what’s being downloaded the most and what that tells us about Free Software usage trends and who else is hosting mirrors in India [7].
