LibreOffice Conference 2017 – Talks from Collabora

We are looking forward to the LibreOffice Conference 2017, starting on October 11 in Rome, Italy! Just like at the previous LibreOffice conferences, there will be talks from people that work at Collabora Productivity, talking about LibreOffice desktop and Online development, new features, security, testing, use cases and a lot more!

You can find more detailed info on the talks from Collabora, ordered by date and time, below:

Filing better interoperability bugs – from users to development

An essential aspect of LibreOffice is that it can work with documents coming from other office suites. During that, however, we are bound to run into interoperability issues. This talk aims to give techniques that can be used by end users and QA people alike to take a closer look at these issues and process the documents causing bugs, without much information about the formats (eg. to create minimal examples), to provide more relevant details to developers in the bug reports.

Speaker: Aron Budea
Room: Sala della Commissioni
Day: Wednesday, October 11
Start: 16:00
End: 16:30

LibreOffice Code Overview

The LibreOffice code-base is huge. Finding the relevant source code for your bug or feature can be challenging initially. The talk will walk though a number of key modules in our codebase and will give a brief summary on them. Also code documentation techniques used in our code (doxygen, per-module README files) will be presented as well. Come and see how to get from the user interface to the relevant source code, what still lacks documentation and how you can help.

Speaker: Miklos Vajna
Room: Sala della piccola Protomoteca
Day: Wednesday, October 11
Start: 16:30
End: 17:00

Quantum computing with VBA

VBA, the programming language of Excel and other Microsoft Office programs, is also interpreted by LibreOffice with more or less success. Among others, the company D-Wave, the world’s first quantum computing company, decided to use LibreOffice for running their VBA script, using its VBA support. The talk will walk through the improvements made on LibreOffice in order to be able to run the above mentioned macro and improve the efficiency of interpreting vba scripts.

Start: 9:30
End: 10:00

Pivot Charts

Pivot charts are a new feature available in LibreOffice 5.4, which introduces the ability for charts to use the output of the pivot table as its source of data. With pivot charts it is very easy to visualize the data and extract the desired information by modifying the pivot table. This talk explains how to create and use the pivot charts, and the experience during development.

Day: Thursday, October 12
Start: 10:00
End: 10:30

Per-Paragraph Signatures in Writer

As security becomes increasingly more important in a highly digital world, signing and validation of digital documents becomes critical. This talk presents a new feature that allows the signing and verification of individual paragraphs in Writer using a cryptographically secure certificate. The signatures are stored as RDF metadata in the document and visually represented by text fields, which shows the signer, date and validity state.

Speaker: Ashod Nakashian
Room: Sala della Protomoteca
Day: Thursday, October 12
Start: 11:30
End: 12:00

Per-Improved interoperability of Writer’s features

Tunneling dialogs to LibreOffice Online

This talk would discuss how instead of reimplementing the same functionality available in various dialogs by writing thousands of lines of code in javascript, we are routing the dialogs from LibreOffice core to LibreOffice Online. I’ll talk about the implementation, routing to LibreOffice Online, and present a demo of the current state. Towards the end, we’ll look into future improvements, scope and further challenges.

Speaker: Pranav Kant
Room: Sala della Protomoteca

OOXML support maintenance

When I meet with users in person the most frequently mentioned issue is that LibreOffice (LO) messes up Microsoft Office (MSO) documents. Well, I understand how frustrating it is, but let’s talk about why it’s this hard to be compatible with MSO. In these days OOXML formats are used most often, so it’s important to have our OOXML filters upodated.
I’ll speak about my experiences about working with OOXML filters. I’ve done some development with different LO components during the last year, so I’ll bring examples from these different areas (Writer, Impress, Calc). The OOXML support of LO has limitations, sometimes it comes from missing features, sometimes it comes from the bad design of filter code. While showing the examples I’ll mention where the code can be improved, what issues you should be aware of while developing this part of the code and also mention some entry points for interested developers.

Approaching the 1M columns / rows limit in Calc Online

The goal of providing to the user the ability of working with a 1 million rows spreadsheet in Calc Online requires several improvements. Some of these improvements have already been achieved and involves special handling of the row/column header, scrolling and document navigation. For row/column header that means fetching only the header heighs/widths for the current visible section of the document. This feature improves both document loading time, minimizes data traffic between the core and client and more responsive row/column operations, such as insertion, deletion or resizing. In this talk will be illustrated how this result has been achieved by the synchronization of header data fetching with mouse/key scrolling and through caching the current cell position.

Making Calc Calculate in Parallel

It seems clear that in the future computers will become more powerful not so much any more by increasing the per-core processing power, but by increasing the number of cores available per processor chip. To take advantage of that in LibreOffice Calc, doing large formula group calculations in parallel is an obvious solution. Earlier, increased parallelism has been approached through the use of OpenCL. This has worked in some ways, and in other ways perhaps been less succesfull than was hoped. This talk describes a new approach which uses plain C++ level multi-threading.

Brute force clang plugins

If we place nice with the hardware, it will make our lives easier. In the old days, we expended considerable effort to make our global analyses more efficient, especially when dealing with large codebases like LibreOffice. However, with the advent of modern hardware and software tools this has become largely necessary. This talk will focus on some pragmatic design choices that lead to being able to run global analysis passes across the LibreOffice codebase, without breaking the bank on hardware or waiting days for results.

How to stop blocking and learn to love non-blocking sockets

The challenge of converting blocking sockets to non-blocking in the production-ready LibreOffice Online, while maintaining quality and stability, was met for the 2.0 release earlier this year. This talk is an overview of the journey from discovering the limitation of blocking socket, and the mechanisms and methods used to build a non-blocking framework and converting the codebase over. The details of how the highly threaded, thread-synchronization-laden design was de-threaded into a simple, single polling-thread model, with callback-scheduling, ownership, life-time management, and thread-affinity is presented.

A year in LibreOffice’s PDF support

The LibreOffice PDF filter got multiple updates during the past year. The introduction of PDF signature verification, signing existing PDF files, rendering PDF images with pdfium and various general PDF export fixes all happened in this period. A new testsuite has been added to catch PDF export regressions early. The talk will walk through a number of situations where improvements have been done and present the results. Come and see where we are, what still needs to be done, and how you can help.
