Interview with Hossein Nourikhah

Which is your perception of the project, as seen from the outside world?
I see LibreOffice project as an alternative path. The road to office productivity suites doesn’t have to end up in proprietary office applications and file formats. LibreOffice project is a way out, trying to provide freedom to the users, alongside providing user friendly, cost efficient products that are also accessible for the disabled people.
On the other hand, LibreOffice is a complex piece of software, consisting of ~10 millions of lines of code [1], which is somehow difficult for an average programmer to get involved in its development. This is something that can be improved through various means, including better tools and documentation, and of course, more helping hands.

How do you see office suites – desktop, mobile and cloud – evolving in the next 10 years?
As software/hardware platforms change, so does the application software, and office suite is not an exception. Being able to run on the mobile devices and cloud is one thing that we see today, but for the next decade, pervasive computing and internet of things seem to be the next platforms. So, being able to communicate with the user through new and challenging input and output channels like TTS, voice recognition and haptic technologies would be something feasible, and perhaps plausible. AI is something essential in this road-map.
I think it is very important for the LibreOffice community to accept these new platforms, and embrace the new ways of communicating with the users, providing the users the freedom and privacy they need in the new era.

Are you a LibreOffice user? Which is your opinion of LibreOffice as a user of desktop software?
Yes, of course! I use the latest Ubuntu LTS, and I am a LibreOffice user on a daily basis. In fact, I was an enthusiastic user of an early version of OpenOffice.org from Red Hat 9.0 in 2003 [2], and I have switched to LibreOffice when it was released.
I am a happy user, although there are glitches in text rendering for my own language (Persian/Farsi). I hope we can fix them sooner with the help of kind LibreOffice developers.

Why did you decide to apply for the position of Developer Community Architect?
For at least two reasons:
Firstly, I wanted to spend my time on a free software that will benefit the people, no matter their skin color, nationality, race and wealth.
And secondly, I wanted to get involved in an international community of developers, and try to attract more and more people, convincing them to use LibreOffice, and encourage them to contribute in the way they can.

Although you have just started working as Developer Community Architect, which is your opinion about LibreOffice source code?
Looking at the history of the code, it is more than 30 years now since the start, and I think there are hidden gems out there! You design a GUI with glade, and at runtime, you can get X, Qt, gtk, etc user interface out of it with visual class library (VCL). This is very interesting.
On the other hand, I think there are a lot of places for improvement, and the most important part of it is from the architectural point of view. Instead of a monolithic application, a multi-process architecture would provide advantages that are available today in some web browsers.

You are from Iran, a country with a huge historical heritage. Can you provide a short description?
Yes. Iran (previously called Persia), is a country from the west of Asia. Currently It spans from Caspian Sea in the north to Persian Gulf in the south. I am originally from Mazandaran, a lovely flourishing area in the southern coast of Caspian Sea with the well known Hyrcanian Forests.
Iran (Persia) has a long history of civilization. Alongside Italy (Ancient Rome), Persia was one the great civilizations of the ancient world. Now, the heritage of the ancient Persia, from the old landmarks to the distinguished scientists and figures spans over several countries. 24 UNESCO World Heritage Sites are currently inside today’s Iran [3], in which most of them are cultural sites, except 2 natural sites of Lut Desert and Hyrcanian Forests.
But besides the long history, it has kind people that want to have a good relation with all the nations worldwide. We also have nice looking Persian kitties that many people around the world love them. 🙂

Which is your operating system of choice, and your preferred development tools?
I use Ubuntu LTS. Debian-based distros are neat, and in case Ubuntu is a platform that I can describe as both user-friendly and developer-friendly. Advanced Package Tool (APT) and Debian Package Manager (dpkg) are great tools that were far ahead of their time, even compared to the commercial software tools from expensive proprietary operation systems. It is very interesting from a user’s viewpoint that you can install any package you like with a single click or a single command:
sudo apt-get install some-pacakge
And it is very helpful from a developer’s viewpoint that you can build a package with just 3 simple commands: Installing dependencies, getting the source code, and building the package is straightforward:
sudo apt-get build-dep some-package (install dependencies)
apt-get source some-package (install the sources)
cd some-package-dir; dpkg-buildpackage -b (build it!)
Let’s remember Ian Murdock (rip), the founder of Debian project and the original creator of these great tools.
I usually use Qt Creator IDE for most of my development work, but I occasionally use Visual Studio Code.

Your personal message to the LibreOffice community, in your native language (and of course in English).
In Farsi/Persian:
پیام من به جامعه لیبره‌آفیس این است: لیبره افیس یک فرصت برای دسترسی به نرم‌افزاری آزاد، دوست داشتنی و بسیار مفید برای کارهای روزمره است. اگر می‌خواهید بهتر شود، باید خودتان کمک کنید؛ چون لیبره آفیس نرم‌افزار خودتان است!
In English:
LibreOffice is an opportunity to have access to a free, lovely and useful software for the daily tasks. If you want it to become better, you should help; because LibreOffice is your own software!

ODF 1.3 is an OASIS Standard

The Document Foundation is pleased to announce that LibreOffice’s native document format – the OpenDocument Format for Office Applications (ODF) 1.3 – has been approved as OASIS Standard with 14 affirmative consents and no objections. ODF is a free, open XML-based document file format for office applications, to be used for documents containing text, spreadsheets, charts and graphical elements. ODF 1.3 is an update to the international standard Version 1.2, which was approved by the International Organization for Standardization (ISO) as ISO/IEC 26300 (2015).

The OpenDocument Format specifies the characteristics of an open XML-based application-independent and platform-independent digital document file format, as well as the characteristics of software applications which read, write and process such documents. It is applicable to document authoring, editing, viewing, exchange and archiving, including text documents, spreadsheets, presentation graphics, drawings, charts and similar documents commonly used by personal productivity software applications.

The most important new features of ODF 1.3 are digital signatures for documents and OpenPGP-based encryption of XML documents, with improvements in areas such as change tracking and document security, additional details in the description of elements in first pages, text, numbers and charts, and other timely improvements. The development of ODF 1.3 features has been funded by donations to The Document Foundation.

ODF Technical Committee has received 3 Statements of Use from The Document Foundation, CIBlabs GmbH, and Collabora Productivity.

ODF 1.3 Specification can be downloaded from OASIS website.

OASIS provides a complete package of the specification and any related files in a single ZIP: https://docs.oasis-open.org/office/OpenDocument/v1.3/os/OpenDocument-v1.3-os.zip

ODF is the only document format which protects the rights of users as digital citizens, and allows transparent sharing of content without disruption, today and in the future.

Update from the ODF Technical Committee

While waiting for the official publication of ODF (OpenDocument) 1.3 as an OASIS Standard, after the approval of the ODF Technical Committee Draft at the end of April 2021, there are a few news updates from the ODF TC which are worth some publicity.

Since 2020, the ODF TC has two co-chairs – Patrick Durusau and Svante Schubert – and four co-editors: Francis Cave, Patrick Durusau, Svante Schubert and Michael Stahl. In the past, there were only two editors, and having doubled the number provides more bandwidth and flexibility.

The ODF TC has recently updated the project charter after more than a decade. The updated document is available on this page. The most important news is the commitment to deliver a Committee Specification Draft at least every year in December, consisting of RelaxNG schemas and written specifications, to avoid a long delay between two consecutive versions of the standard as in the recent past.

The ODF TC also aims to provide a fast-track for new ODF features of implementers, and publish the basic description (OASIS Committee Specification) more frequently, so features can be quickly  reviewed and embraced into an ODF Specification without the need to use the intermediate LibreOffice External namespaces (lo-ext), with all the associated delays and costs.

In addition, Michael Stahl and Svante Schubert have collected all the technical tooling required for the publishing of the ODF specification and the specification artefacts into an OASIS Github repository: https://github.com/oasis-tcs/odf-tc. The aim is to be able to deliver all specification deliverables by automation from command line, to become more agile, and improve transparency and quality by adopting modern toolings.

Last, but not least, the ODF TC is considering an ODF Plugfest in 2022.

Hossein Nourikhah joins the TDF team as Developer Community Architect

Next week, Hossein Nourikhah will join the team at The Document Foundation, the non-profit behind LibreOffice, as Developer Community Architect. Hossein is a developer, university lecturer and FOSS advocate. He writes programs, teaches programming to students, and is an advocate for the use of free software applications, because they have a huge positive impact on the quality of our life by providing the essential freedoms that we all deserve.

Hossein has a B.Sc. in Computer Engineering (Software) from Isfahan University of Technology, and a M.Sc. and a Ph.D. in Information Technology from Amirkabir University of Technology, also called the Tehran Polytechnic. Since 2016 he has been an instructor at the Amirkabir University of Technology, teaching various courses including C/C++ programming, operating systems, software design, and many others.

Hossein started programming in BASIC and Pascal when he was 12, and after two and a half decades he is still involved in programming for fun and profit. He has worked with several programming languages, including C/C++, Java, Pascal, PHP and many more.

Industry experience

In addition to the university activities, including teaching and research, Hossein has several years of experience in the industry, working at various software/hardware companies as a C/C++/Java programmer – and lately as a software team manager and lead developer.

Hossein’s work experience ranges from web development with PHP to industrial application development with C++/Qt. He considers Qt a great platform for C++ software development, and he likes it very much as a clean and lovely tool.

Hossein has worked with many programmers as mentor, helping them to improve and reach their potential in software development by better understanding programming languages, libraries and tools. He feels great when he can empower other people, also because this helps him to expand his knowledge and understand things much better than before.

As Developer Community Architect, Hossein will be responsible for attracting new contributors to the LibreOffice project by identifying and onboarding new potential developers, building relationships between them and the community, and introducing them to TDF’s communication channels – where they will meet fellow co-hackers. He will encourage everyone’s contribution, and show community members ways to grow by bringing the more skilled contributors in contact with existing experts in the various fields for even deeper learning.

We’re happy to have him on board, and look forward to working with him!

100 Paper Cuts as a new student mentoring activity

Just before the pandemic, the Board of Directors of The Document Foundation approved a budget to launch an educational program targeted to universities, where students at selected tech schools would receive an economic incentive to promote LibreOffice amongst their peers, with the objective of increasing the number of young contributors both in source code development and in other areas. Unfortunately, the pandemics has forced all universities to stop all collateral activities, and this has resulted in the program being frozen for over one year.

Although the situation is not yet back to normal, we have the opportunity to mentor a student in Turkey. Muhammet Kara, a member of the MC and a Collabora full time developer, will mentor Ahmet Hakan Çelik, an undergraduate computer science student at Çanakkale Onsekiz Mart University, who will be working on 100 Paper Cuts – a list of bugs and enhancement requests relating to LibreOffice’s user experience – during June and July, trying to solve as many issues as he can. The target is to collect 10 points.

This is a first step in the direction set before the pandemic. We are planning to make similar announcements soon.

After the summer, if the academic activities will be back to normal – although the recover will be slow, and will have to cope with entirely new regulations – The Document Foundation will be able to get back in touch with the universities to start the planned Ambassador Program.
