If you already have experience at Zephyr, please join this session and help answering the attendee's questions.

Printing and scanning in immutable operating systems and sandboxed packaging (OpenPrinting)

• Till Kamppeter (OpenPrinting/Canonical)

Room: Room 1 [Immutable Linux operating systems](https://ubuntu.com/blog/ubuntu-core-an-immutable-linux-desktop) get more and more talked about as they are more secure and much easier to maintain. Especially with their smartphone-like way of packaging and distributing applications and system components they are also a way to make Desktop Linux more attractive to end users. This different system architecture also affects printing. We need a safe way of letting third-party application developers acess the printing system withiout being able to mess it up or access files of other users. We also need a way for printer (and scanner) manufacturers to add drivers without need of the whole immutable system core to be replaced, ... The [New Architecture](https://openprinting.github.io/current/#the-new-architecture-for-printing-and-scanning) helps towards this new system realm by its all-IPP approach only using network-based communication protocols. Here the changes and methods are presented and possible approaches and solutions discussed.

ScaniVerse: A New Horizon in Unified Scanning for Linux Systems (OpenPrinting)

• Akarshan Kapoor (Indian Institute of Technology, Mandi, India)

Room: Room 1 TALK SUMMARY "ScaniVerse: A New Horizon in Unified Scanning for Linux Systems". In this fast-paced 20-minute talk, I will introduce ScaniVerse, a unique project poised to revolutionise the scanning landscape across all Linux systems.I will navigate through my journey of extending PAPPL, an open-source printing system, to embed scanning capabilities by metamorphosing non-ESCL scanners into ESCL servers. Furthermore, I will be illustrating an innovative MetaScan system, a smart data cataloguing module for scanned images. ScaniVerse is a testament to the power of open-source networking in crafting innovative, adaptable solutions, and heralds a new era in device interaction. PROJECT DESCRIPTION ScaniVerse is an innovative project set to revolutionize scanning technology, spearheaded in two directions. The first part, implemented by me in GSoC (Google Summer of Code) under the mentorship of Mr. Till Kamppeter, involves extending the Printer Application Framework, PAPPL, to support the eSCL (AirScan) protocol, thereby converting non-eSCL scanners into eSCL servers to significantly enhance their cross-platform interoperability and functionality. The second part, inspired by my GSoC work, is the development of MetaScan, an intelligent scanning frontend prototype that facilitates smart categorisation and archival of scanned images using a combination of OCR, machine-learning-based image recognition, and a dynamic metadata tagging system. When integrated, these components form the robust ScaniVerse framework—a sandboxed Scanner Application compatible with all Linux Systems. This project underscores the transformative potential of open-source networking in creating innovative, unified solutions, thus pioneering the next generation of scanning systems. LEARNING OUTCOMES Participants will gain insights into the process of working with and extending an open- source system from scratch through my GSoC Journey, the development and functionalities of MetaScan, and the exciting potential that lies in the convergence of scanning and printing technologies. You'll also learn about the transformative power of open-source networking and how it can innovate, unify, and streamline solutions. I invite passionate individuals to contribute and participate in this innovative journey. Upon completion of the session, those interested can get involved with ScaniVerse by contributing to the GitHub repository links, or directly reaching out to me.

The Fundamentals of Effective Technical Writing (Documentation)

• Hrittik Roy (CNCF Ambassador)

Room: Room 1 There aren't many days when you don't come across blogs or documentation while working in tech.Technical writing is an important skill for professionals in the tech industry, as it allows them to clearly and effectively communicate technical information to their audience. Whether you are writing a blog post, creating documentation for a software application, or producing a user manual, effective technical writing is essential for ensuring that your message is understood by your readers. This talk covers the fundamentals so your next piece of content will be well-organized, easy to understand, and something you can leverage to grow your career.

Can documentation be fun? (Documentation)

• Dimple Kuriakose (Canonical)

Room: Room 1 In this talk, we’ll delve into different aspects of documentation – both from a technology perspective and from a people perspective. We’ll consider information architecture, automation, quality and means of getting things done. We’ll try to answer questions like “How to make documentation useful and yet easy to use?”, “How to ensure an easier life for both the producer and the consumer of documentation?”. In the process, we’ll hopefully figure out if documentation can be thought of as fun or not.

Desktop Linux, as easy as a smartphone! Just in a Snap! (OS Distributions and Packaging)

• Till Kamppeter (OpenPrinting/Canonical)

Room: Room 1 Have you already thought about how the applications we develop get distributed to end users? Often developers only provide the source code. So for not so tech-savvy users the major distributions need to pick up projects and package it, and maintain it for new releases. This is why there is a need for distribution-independent, secure, and easy-to-use packaging, like on smartphones. This exists also for Linux ... Among the options, there is [**Snap**](https://snapcraft.io/about)! Applications are easy to find in the Snap Store and they are installable on most Linux distributions. And, to make Linux even easier for end users, we cannot only provide applications in the Snap format, but also have an all-Snap operating system, [Ubuntu Core Desktop](https://discourse.ubuntu.com/t/ubuntu-core-desktop-deep-dive/), an [immutable core operating system](https://ubuntu.com/blog/ubuntu-core-an-immutable-linux-desktop) based on Snap. All this is based on the knowledge and experience we gained at Canonical when creating the smartphone operating system [Ubuntu Touch](https://ubports.com/). After the phone project having been discontinued we started with the IoT system Ubuntu Core, snapped desktop applications, ... More about Snap: [The Powers](https://www.youtube.com/watch?v=TfB6QwR2GYg), [The People](https://www.youtube.com/watch?v=ido6kGmSHWI) **And if you eager to learn snapping now, come to our workshop after this talk!**

A sneak peek into the realm of immutable Linux distributions (OS Distributions and Packaging)

• Rudra Saraswat (Ubuntu Member and Project Lead of Ubuntu Unity)

Room: Room 1 Traditionally, you would use your system package manager to install all kinds of software ranging from compilers to IDEs and games, but this has changed lately thanks to the advent of new packaging formats such as Snap and Flatpak, which has encouraged new as well as some existing Linux distributions to adopt read-only root filesystems and atomic system updates. If you want to get familiar with them, this talk is for you. I'll be using blendOS as an example.
