  • Mail & catch-up with Kendy. Lunch.
  • Pleased to see the work we have done together released announced as Nextcloud Office which will be the default Office in Nextcloud from now on; looking very slick. A few points:
    • Lots of that coding touches Collabora Online and is already included and published in CODE 21.11, and of course we build on LibreOffice Technology so that work is also already contributed and will go into the next LibreOffice releases.
    • From a customer and support perspective we continue to work together as before to deliver excellent support to all of our customers and users as today.
    • Naturally we are thrilled that Nextcloud joins a long list of other partners and OEMs that choose Collabora Online as their default option, very often white-labelled.
    • Nextcloud Office built on COOL and LibreOffice Technology
    • Interested by Richard Moore (head of MI6)'s take on data traps
      "The data-trap is this: that if you allow another country to gain access to really critical data about your society, over time that will erode your sovereignty - you no longer have control over that data."


A quick news update from Germany: the upcoming coalition government endorses free and open source software. In the coalition agreement (German), there are some key sentences on this topic, for instance:

Development contracts will usually be commissioned as open source, and the corresponding software is generally made public.

Another section states:

In addition, we secure digital sovereignty, among other things through the right to interoperability and portability, as well as by relying on open standards, open source and European ecosystems, for example in 5G or AI.

We are encouraged to see FOSS being considered by the incoming government, along with other news such as the north-German state of Schleswig-Holstein switching to LibreOffice and free software.

  • Up early, Julia-Anne & Isaac's wedding - spent some time setting up the reception venue, before heading to the wedding venue at Clare Country Park. Got quartet bits setup, Jitsi streaming (made worse by remote user-muting (and no ability to then un-mute) of the stream) of the event, and after an awkward hiatus realized I was supposed to be leaading parts of the service - so tried to get the various bits into the order with Cannon White leading the service. Stayed & locked up after photographs.
  • Lovely reception, food, speeches & some dancing - interesting company; drove back through snow / blizard, bed late.

Brussels, November 26 – A coalition of EU software and cloud businesses joined Nextcloud GmbH in respect of their formal complaint to the European Commission about Microsoft’s anti-competitive behavior in respect of its OneDrive (cloud) offering. In a repeat from earlier monopolistic actions, Microsoft is bundling its OneDrive, Teams and other services with Windows and aggressively pushing consumers to sign up and hand over their data to Microsoft. This limits consumer choice and creates a barrier for other companies offering competing services.

Over the last few years have grown their market share to 66% of the EU market, while local providers lost out from 26 to 16%. By heavily favoring their own products and services (so-called “self-preferencing”) or outright blocking other vendors they leverage their position as gate keepers to extend their reach in more and more neighbouring markets and push users deeper into their ecosystems. Local, more specialised vendors are unable to compete “on the merits” as the key to success is not a good product but the ability to distort competition and block market access.

“This is quite similar to what Microsoft did when it killed competition in the browser market, stopping nearly all browser innovation for over a decade. Copy an innovators’ product, bundle it with your own dominant product and kill their business, then stop innovating. This kind of behavior is bad for the consumer, for the market and, of course, for local businesses in the EU. Together with the other members of the coalition, we are asking the antitrust authorities in Europe to enforce a level playing field, giving customers a free choice and to give competition a fair chance,” said Frank Karlitschek, CEO and founder of Nextcloud GmbH

The European Commission’s Directorate-General for Competition exists precisely for the purpose of preventing this kind of abusive behavior and keeping the market competitive and fair for all players. Nextcloud GmbH has filed an official complaint with the European Commission’s Directorate-General for Competition about the abusive practices of Microsoft related to OneDrive. Nextcloud GmbH has also filed a request with the German anti-trust authorities (the “Bundeskartellamt”) for an investigation against Microsoft and is discussing a complaint in France with its coalition members.

Dozens of European SMEs organisations support these efforts to push back against Big Tech and create a level playing field, supporting innovation and local (European) businesses.

A full list of these companies as well as non-profits and industry consortia can be found on https://antitrust.nextcloud.com. On the same page, there is also a list of the media coverage.

There are many situations that you need to use numerical constants in your code. If you use numerical literal values directly instead of symbolic constants, it can cause problems. For example, consider this piece of code that calculate area of a circle:

double area = 3.14 * r * r;

This is not OK, because:

1. The value of π is not 3.14 nor 3.141592. π is an irrational number, and the suitable value depends on the number of decimal places that you can/want to use among unlimited decimals of π.

2. Suppose that you want to change the numerical literal to increase the number of decimals that you use. You should search for 3.14, and check one by one to see if it is actually π, or it is another 3.14 unrelated to the well-known mathematical constant.

C++ logo

C++ is the main programming language used in the LibreOffice development

Using symbolic constants

A better code can be:

double area = M_PI * r * r;

and with more long and meaningful name for variables:

double circle_area = M_PI * radius * radius;

Because of the above mentioned problems, it is better to use some numerical constant instead.

ES.45: Avoid “magic constants”; use symbolic constants

If it is well-known (like π), you should use the appropriate symbolic constant like M_PI. If not, you should define a new constant with proper name and type with ‘contsexpr’.

One solution to find such magic constants is to start from a list of some well known mathematical constants:

Then, store some of them in a text file, let’s say ‘constants.txt’, then search for all these values inside C++ files:

git grep -Ff constants.txt *.cxx *.hxx

Many of these symbolic constants like M_PI already exist in C++ standard library or some place in the LibreOffice code, and you can use them easily.

You should examine the ‘grep’ results carefully, because not every 3.14 refers to PI.

Final Notes

Besides fixing the bugs, there are many places to work on improving the code, and some of these are listed as EasyHacks. The specific improvement that is discussed in this blog post is filed as tdf#145759.

If you want to work on this improvement about using symbolic constants, but you need to know how to get started with LibreOffice development, I suggest you to see our video tutorial:

  • Mail, quick planning call, took M. for her 'cello exam to Haverhill on to Deja-vu for a comforting coffee; dropped her back to school; to work. Mail & meetings, catch-up call with an old partner.

Today we’re talking to Bayram Çiçek, who’s helping to implement new features in LibreOffice has part of the Google Summer of Code…

Tell us a bit about yourself!

I live in Çanakkale, Turkey. I’ve just graduated with a bachelor’s degree in Computer Science from Çanakkale Onsekiz Mart University.

When I was a student, professors and instructors always told us about the importance and benefits of contributing to free and open source projects like LibreOffice. Since I was a LibreOffice user for years, the idea of not just being a user – but developing it, to go beyond being a user – has always been exciting to me. Therefore I decided to contribute to LibreOffice.

In November 2020, Hacettepe University organized an event called “ACM Hacettepe Lectures”. I attended the course “Contributing to Open Source Projects with C++” by Muhammet Kara. We sent our first patches to LibreOffice and Collabora Online together with other attendees, and this is how my journey began.

Then, I decided to apply to Google Summer of Code 2021, and I was lucky enough to get selected as a student under the mentorship of Muhammet Kara and Heiko Tietze, in the past summer. I worked on the most-annoying bugs, and tried to fix as many bugs as I could during GSoC.

What are you working on in the LibreOffice project right now?

Currently, I’m working on Tables in Writer, and hoping to add a diagonal-borders feature to it. After gaining some more experience, I’ll be working on some bugs that related to my GSoC project, as I mentioned in my GSoC final report.

Why did you decide to become a member of The Document Foundation?

I think contributing to LibreOffice is both fun and sometimes challenging. When ‘fun’ and ‘challenge’ come together, it creates a great community, as LibreOffice does; and being a part of this community makes you more passionate and stronger. And that’s why I wanted to become a TDF member.

Anything else you plan to do in the future?

I will work on most-annoying bugs and I’ll be fixing as many bugs as I can in the future. Also, I want to actively contribute to Collabora Online.

On the other hand, I’ll continue to contributing to Turkish translation of LibreOffice and I want to be an active member of Turkish Community to spread the open source usage and LibreOffice.

Many thanks to Bayram for all his contributions, and enthusiasm in our community! And to everyone reading this: Find out what you can do for LibreOffice – have fun, build up your skills, and do awesome things 😊

The north-German state of Schleswig-Holstein plans to switch to open source software, including LibreOffice, in its administration and schools.

In doing so, the state wants to reduce its dependence on proprietary software, and eventually end it altogether. By the end of 2026, Microsoft Office is to be replaced by LibreOffice on all 25,000 computers used by civil servants and employees (including teachers), and the Windows operating system is to be replaced by GNU/Linux.

The necessary steps for this are specified in the planning of the Schleswig-Holstein state parliament (German), as digital minister Jan Philipp Albrecht explains in an interview with c’t (also German – Google Translate version here).

Lothar Becker and Thorsten Behrens from The Document Foundation, the non-profit entity behind LibreOffice, were invited to a meeting with those responsible (photos below). The focus was on cloud solutions, integration with LibreOffice and other systems, and video conferencing tools.

We at the Document Foundation are pleased that LibreOffice is being used in public institutions, and hope that more federal states, governments and other organisations around the world will join the migration.

When working with shapes and charts in LibreOffice, there are several occasions that you have to calculate tan-1x. But is atan function always the best choice? Here we discuss using atan2 function instead of atan in C++ code. When used in correct place, atan2 can have a lot of benefits when calculating atan ( y / x ).

Unit circle

Unit circle

If you use atan(x) to calculate the output θ, you have to think about different situations that may occur, because with the same value of x, there are multiple values of θ, and it would be your responsibility to handle that, and find out what is the suitable value of θ.

But, if you have two values y and x, and you want to calculate atan(y / x), there is a better choice: using atan2(y, x). As discussed here, atan2(y, x) can handle the values from all the 4 different quadrants.

This is the formula for atan2(y, x):

atan2 formula

atan2 formula

In this way, you don’t have to check the sign of x and y because atan2() does this by itself.

There are some places in the LibreOffice core that is currently using atan, and atan2 is more suitable. For example, in hwpfilter/source/hcode.cxx:

1447 double angle;
1448 angle = (180 / PI) * atan( ( y2 - y1 ) * 1.0 / ( x2 - x1 ));
1449 if( y2 >= y1 ){ /* 1, 2 quadrant */
1450      if( angle < 0. )
1451            angle += 180.;
1452 }
1453 else{ /* 3, 4 quadrants */
1454      if( angle > 0 )
1455            angle += 180.;
1456      else
1457            angle += 360.;
1458 }

A better choice would be this one single line:

1458 double angle = basegfx::rad2deg(atan2(y2 - y1 , x2 - x1));

Instead of multiplying the output of atan() by (180 / PI) to get degrees out of radians, we simply use basegfx::rad2deg() for the conversion, and also using the atan2(), those conditions would be superfluous, and are removed.

Finding instances of atan to replace with atan2

This grep command shows the instances of the similar situations:

git grep atan\(

Within the results of the grep, you can find places that atan2() is better. You should take care about the conditions that may be present (or missing) after the atan(). These conditions usually check the sign of the numerator and denominator in the fraction passed to atan(). Make sure that the code works correctly after removing them.

Final Notes

Besides fixing the bugs, there are many places to work on improving the code, and some of these are listed as EasyHacks. The specific improvement that is discussed in this blog post is filed as tdf#145630, and you can submit patches for this improvement  to LibreOffice Gerrit.
