Post-FOSDEM

It was a great FOSDEM again, with a lot of presentations, speakers, and participants. We met a lot of people during those days and it was great to catch up with them. Most of the time our team was at the LibreOffice booth in the K building at the main hall, or at Open Document Editors devroom.

Missed our talks?

If you missed our talks because the rooms were pretty full or because you couldn’t attend FOSDEM please have a look at the registrations and slides:

Re-structuring a giant, ancient code-base for new platforms

How LibreOffice is meeting the challenges of new platforms both hardware and software, adapting to new constraints & shining.

Calc: The challenges of scalable arithmetic

How we threaded the Calc core to get some great efficiency wins on the new deeply threaded Ryzen era.

EPUB export in LibreOffice Writer

LibreOffice Writer was always capable of exporting your document in a portable way in the form of the PDF filter. Today many users read reflowable content in EPUB, which is the new PDF to some extent. This work is done by integrating the libepubgen Document Liberation library and by improving both the library and LibreOffice itself along the way. Come and see how it’s implemented, where are the still rough edges and how you can help.

Dialog tunneling in LibreOffice Online

LibreOffice on the desktop is very feature packed office suite. One of the complaints that power users make in Online is that it lacks many of them: they cannot add colored borders in their paragraphs, manage tracked changes/comments, correct the spelling and grammar in the document, etc. The question is how do we bring these functionalities to the cloud at your disposal in your browser tab?

On Saturday night it was community time, where we had dinner with all the LibreOffice contributors at Betacowork, the same location where we had two days of LibreOffice Hackfest on Monday 5th and Tuesday 6th of February.

See you again next year at FOSDEM!

Come see us at FOSDEM 2018!

FOSDEM is a free event for software developers to meet, share ideas and collaborate. Every year, thousands of developers of free and open source software from all over the world gather at the event in Brussels for two days focused on promoting the use and development of free and open source software (FLOSS).

When and where

From 3rd-4th February’18, FOSDEM takes place in the beautiful city of Brussels, Belgium. It provides FLOSS developers and communities a place to meet and get in touch with each other, attend interesting talks and presentations on various topics by project leaders and committers, get informed about the latest developments in the open source world, and more.

We will be there…

Our team is attending FOSDEM this year and we will have several talks:

Re-structuring a giant, ancient code-base for new platforms

Come and hear how LibreOffice is meeting the challenges of new platforms both hardware and software, adapting to new constraints & shining.

Day: Sunday, February 4
Start: 12:00
End: 12:50

What is this talk about? – Michael Meeks had an interview as a main track speaker to explain more details regarding his talk. For more details read his interview on the FOSDEM website.

Calc: The challenges of scalable arithmetic

Come and hear the story of how we threaded the Calc core to get some great efficiency wins on the new deeply threaded Ryzen era. Hear about the rather complicated Calc-ulation core, and see how we used tool to profile and optimize from cachegrind, oprofile, perf and many others. Discover some of the challenges of spreadsheets, why it’s perhaps not quite as simple as you might hope, see how we tried to make this maintainable and test-able.

Day: Saturday, February 3
Start: 16:00
End: 16:30

Hope to see you there!
