A Business Perspective on Open Source – The Enterprise Open Source Day

Business perspectives on Open Source

Together with our friends and partners from Factor Group, Canonical, Nextcloud, Linbit, and OpenNebula, we will be highlighting business perspectives on the use of open source in the enterprise during Enterprise Open Source Day on 10 November 2021. The summit will feature talks from leading industry leaders such as Mark Shuttleworth, Frank Karlitschek and Michael Meeks. Details of the program are available on the event page.

Open Source in large organizations

Open Source is becoming more and more important for businesses building secure collaboration platforms. Over the last years, the various platforms have matured and are as capable, and often better than proprietary solutions, to offer the scale, security and integration large organizations need.

With our partners, we are pleased to invite everyone to participate in the Enterprise Open Source Summit, a virtual event focused on transition strategies and the subsequent successful use of open-source solutions in the corporate environment.

The summit will take place on November 10, co-organized between open-source industry leaders Canonical, Nextcloud, Collabora and Factor Group as well as Linbit and OpenNebula.

Program

Each of us has years of experience with open source in finance, retail, energy, manufacturing, telecommunication, public sector and other areas. We will share our knowledge in a program of keynotes, lightning talks and demos, bringing several customers to talk about their experiences as well. Participants will be able to get answers to their questions first-hand from industry leaders.

The following questions and strategies will be discussed at the event:

  • Migration from deployed commercial products to open-source solutions
  • Commercial support for open-source solutions and related concerns (scaleability, stability, integration, vendor lock-in and more)
  • Security and creation of fault-tolerant solutions

Find a more complete overview of the program on this page.

Tickets for the Enterprise open-source Event are available at 150 USD. However, different early bird options are available, offering significant discount on the admission. Secure your seat at the event page.

 

 

GSoC 21 Projects mentored by Collabora for LibreOffice

Collabora mentors students on LibreOffice projects during this year’s Google Summer of Code

Summer is synonymous with the opportunity to participate in beautiful projects. Let’s look at the students who work in improving LibreOffice during the Google Summer of Code. This year, four of the approved GSoC projects for the LibreOffice community are mentored by Collabora developers. Find out about the improvements they are currently implementing!

Tests for the VCL graphic backends

The Visual Class Library (VCL) tests identifies if a graphic backend works correctly. This is especially important if the backend depends on the client hardware or drivers (like e.g. on Skia/Vulkan). This task’s main objective is adding more test cases to the pre-existing tests, and implementing a usable UI for users to test the graphic’s feasibility themselves. This project can be considered as of medium difficulty and requires C++ knowledge. It has been taken over by Akshit Kushwaha who is being mentored by Collaborans Tomaž Vajngerl and Luboš Luňák.

Creating a powerful Text Style deck

Text Style deck mock-up by the LibreOffice design team

The current styles deck sidebar is going to see a redesign. The paragraph and character styles will be merged into a single Text Style deck, as illustrated in the mock-up to the left. Furthermore, Anshu Khare, who has picked-up this project, does also want to rework the filter workflow. Anshu Khare is being mentored by Collaborans Tomaž Vajngerl and Mike Kaganski and Heiko Tietze from the LibreOffice design team.

Making SVM format independent of the VCL Metafile

The SVM file is a 1-to-1 pullout of the content of the VCL Metafile. We mentioned the VCL already before. It is a complex code area and since the SVM should not change, stay consistent, modernizing and updating VCL is very hard. Now after this task, there will be a test for the SVM format. And there will also be new classes, making it easier to update/improve VCL. This project can be considered of medium difficulty. It is being taken over by Panos Korovesis who is being mentored by Tomaž Vajngerl and Miklos Vajna.

100 paper cuts

100 Paper Cuts is a versatile and multifaceted project in which Bayram Çiçek will be implementing enhancement requests and solving some issues on the UX side of LibreOffice. This requires knowledge in C++ and the ability to read other peoples code. Due to its nature, the difficulty of this project can vary. Bayram Çiçek is being mentored by Collaboran Muhammet Kara and Heiko Tietze from the LibreOffice design team.

More Projects – Boost.Gil 2D convolution and correlation

Apart from those for the LibreOffice project, Collaboran developers participate in other Google Summer of Code projects. For the Boost C++ Libraries organization, a 2D convolution and correlation algorithm aligned with existing 1D convolution and correlation is to be implemented. Prathamesh Tagore will improve the existing prototype and make it ready for release. He is being mentored by Collaboran Pranam Lashkari, who was himself a successful GSoC scholarship holder a few years ago.

We wish all participants an equally successful and insightful summer and would like to thank all mentors for devoting the time necessary for the success of these projects. At Collabora, we believe that the sharing of knowledge is an essential part of open source and also a driver of progress and innovation.

Searching for a mentor? Join us GitHub!

Google Summer of Code is an excellent opportunity to learn to work in many open-source projects. But where to find mentors during the rest of the year? We suggest you to take a look at the code of Collabora Online on GitHub and join the growing community there, with easy hacks to get started and regular round-ups. Community Mentor Muhammet Kara and the rest of our team of open-source developers are there and willing to share their vast experience.

Collabora to integrate Collabora Online with ownCloud Infinite Scale

 

Nuremberg, Cambridge, October 27th, 2020 – A broad open-source ecosystem is already building around the new ownCloud file platform. Now Collabora, too, announces an integration with ownCloud Infinite Scale.

ownCloud is working on a new file platform modernized from the ground up. Already, a broad ecosystem of open-source software has pledged to support the upcoming ownCloud Infinite Scale with integrations. One of the integration partners is Collabora, the company that brought LibreOffice into the cloud.

Integrating its open-source browser-based office suite Collabora Online with the new ownCloud file platform, Collabora enables existing customers to seamlessly migrate from ownCloud 10 to ownCloud Infinite Scale. This means that they can leverage the substantial improvement in performance and scale right from the start.

The combination of Collabora Online and ownCloud Infinite Scale enables users to productively work on documents, spreadsheets, presentations and more, right from within ownCloud and in their browser. It enables teams to collaborate in real time, with changes shown to all collaborators as they happen. Deployed on-premises or in a cloud of choice, ownCloud and Collabora provide organizations with a secure and sovereign workspace they fully control.

Collabora and ownCloud are already in a fruitful long-term partnership, providing Collabora Online for ownCloud Enterprise together.
They also jointly developed the data room feature Secure View. It makes the sharing of sensitive documents more secure by restricting the available actions for viewers and by identifiably watermarking documents. In addition, documents are displayed as images in users’ browser and the files strictly remain on the server at all times, providing the most secure data room service.

“For our new file platform ownCloud Infinite Scale, we follow a best-of-breed strategy of seamlessly integrating with strong solutions in the open source ecosystem”, explains Tobias Gerlinger, CEO of ownCloud. “We are especially pleased that Collabora Online as one of the flagship solutions in the open source community is already in the process of integration with ownCloud Infinite Scale.”

“We are excited about developing the integration of Collabora Online with ownCloud Infinite Scale. It is the logical next step in our long and fruitful partnership”, says Michael Meeks, General Manager at Collabora Productivity. “It enhances the usefulness of our products for customers, providing their staff with productive and secure workspaces that scale and perform.”
