The full adoption of OOo in the Cambodian education System

KHENG Piseth, KHOEM Sokhem ( / KhmerOS)

Abstract: The Cambodian Ministry of Education mandated, in january 2008, that all public educational institutions must use - for teaching the use of computers - OpenOffice in Khmer language. The announcement was done together with the presentation of the new official ICT textbook of the Ministry, which mainly teaches OpenOffice (together with other FOSS programs). The 350-page full-color textbook has been one of the key factors that have led to adoption of OpenOffice. It has been the last of a number of actions that have led to the end. As the Ministry of Education is concerned, OpenOffice started to exist in 2004, when it included the use of FOSS as part of its "ICT for Education" policy, as an effect of lobbying from the KhmerOS project, which was at that time translating OpenOffice to Khmer. For two years, OpenOffice started being used non-officially in many of the schools. As it was the only software in Khmer language, it was easy for the teachers to teach it. The KhmerOS project provided tranining materials (slides), but lack of LCD projectors forced teachers to use their own methodology. In 2007 the Ministry and the Open Institute (NGO that houses the KhmerOS project) signed an agreement to work together to develop ICT in Education and to write together a 5-year Master Plan for the implementation of ICT in Education. The Master Plan is still in the process of being written, but the close cooperation, together with the ICT Textbook (developed and distributed free of charge to all schools by the Open Institute), together with a campaign to train all the ICT teachers in all upper secondary schools created sufficient trust in the Ministry to mandate the change to OpenOffice. The keys to this sucess have been: close cooperation with the Ministry, working on policy from the beginning, development the training materials, doing teacher training, and integration of this work with the needs of the Ministry and the country. Another key factor has been having donor countries (Spain and Germany) that have funded salaries and book printing.

Back in the Brazilian public administration

Ferreira Filho, Claudio (President / Lead NLP pt-BR / / NLP pt-BR)

Abstract: The initiative to adopt in Brazil began in 2004, when the Free Software adoption effort started inside the Brazilian Federal Government. The goal was to migrate all types of software, both desktops and servers. Beyond that initiative, other approaches began, like standardizing of documents' formats, but the process revealed itself as extremely slow and with collateral results: the low level of satisfaction after migrations and for various factors the inability to fulfil the basic requirements. This year, the Brazilian Federal Government organized the Free Software Implantation Committee, which is responsible for the definition of the strategies to effective migrate. The main initiative detected by this committee to consolidate de process is the adoption of This work presents the migration success cases of different federal departments with their interactions with the community and the building of a market inside Brazil, the strategies adopted by those departments and their concerns regarding the sustainability of Br/ project. Besides that, it also tries to present the Committee actions, its planning and strategies, side by side with the and ODF Alliance community activities inside Brazil to create an ideal environment for that migration, such as, amongst other, standardization of ODF at ABNT (Brazilian Organization of Standards), work of the user groups in the various states to encourage the creation of laws supporting ODF, not only in the states but also for the whole country.

Visualize Writer Document Structure for Productive Development

Jian Hong,Cheng (STAFF SOFTWARE ENGINEER/Technical Leader / IBM)

Abstract: This presentation introduces a tool that can be used to picture the node types and structure,frame types and structure, portion types, and other data relations information in an OpenOffice writer document. Because of plentiful data types and complicated relations in a writer document,developers are easily plunged into disordered situations when tracing them and their relations. Under certain scenarios,when operating these complex contents,the nodes structure or frame structure or data relations may be damaged unexpectedly,which lead to serious problems. And generally,these problems are difficult to solve. For example,when opening a given special document,and doing the addition/deletion operations for the text of "End of Footnote" and "Start of next page",Writer will meet serious problem. The reason is that the sample file has an abnormal setting about footnote height. The height of footnote is set to be a pretty tiny value: ?0.2? inch which may not be high enough to contain a single normal text string. This setting makes a huge barrier when formatting the document content, and also,this document is displayed in a very strange way. For example,each footnote can not be displayed in its own page, but in the following page. In this case,if the text input into the text field of "End of Footnote" or "Start of next page" is too long and can not be displayed totally in a single page, it has to be spanned to cross pages when formatting. Actually,the process will not affect the document nodes structure. During said formatting process,all footnotes will be reorganized within multi-frames. In order to deal with the multi-lines of the footnote, a method named SwFlowFrm::PasteTree(...) will be executed to connect all text strings inside a single footnote. Please refer to the code segment. ... else { if ( 0 == (pStart->pPrev = pParent->Lower()) ) pParent->pLower = pStart; else pParent->Lower()->pNext = pStart; } ... Said code will move a sub tree whose root is ?pStart? into the node ?pParent? as a child. If the "pParent" does not have any child,the "pStart" will be the only child of it. And if the "pParent" has already a child, the "pStart" will be the sibling child. But if the "pParent" has more than one child nodes,the former child node and its sibling nodes will lost their relationships to the whole tree. Thus,any modification of the tree will not affect the former child node and its sibling nodes any more. In this case, the content of the ?pParent? will be moved backward again and then, the "pParent" will be destructed later. Because the relationship of said nodes are lost, there will be no any operation happening on those said nodes. So the upper node pointer of such nodes is still pointing to the memory where the ?pParent? has been in. A dangling pointer appears. Serious problem will happen at any time. When facing such serious problems appeared during document formatting,developers have to make the data structure and relations clear first,and then plunge into code ocean to trace the complex formatting process step by step,that's a real big headache and will take too much time. And now,with the help of this tool,developers can easily make the data structure and relations clear and catch the destroyed data and certain structure difference changed within certain process,especially such as formatting process,undo/redo process and so on. Thus,developers are able to find out the root cause quickly and work out solution in time. This tool makes Writer developers more productive. Simultaneously,the development of the tool and real example details will also be introduced in this presentation.

The state of the OOo SCM migration project

Rechtien, Jens-Heiner (Release Engineer / Sun Microsystems)

Abstract: is looking for some time now for a new SCM (Source configuration management) tool to replace CVS. Due to the rapid changes in the SCM tooling landscape over the last years there is no obvious best replacement for CVS; at least four SCM tools (Bazaar, Git, Mercurial and Subversion) emerged as serious candidates for hosting the OOo source code repository. The OOo engineering steering committee decided to migrate to Subversion first but to re-evaluate the three DSCM systems within a year to account for new developments. This presentation will discuss the current state of the SCM migration project.



Building Windows OOo on Linux: Madness, or The Way?

Holesovsky, Jan (Developer / Novell, Inc.)

Abstract: Producing Windows OOo builds is very painful - not everyone has that operating system, setting up the build environment for OOo is non-trivial, and the build takes too long. On the other hand, the Windows builds are essential, far too many users demand them, and also they are necessary for the QA purposes. This session will discuss the possibilities to cross-compile the OOo on Linux using the free (as in free beer) Microsoft compiler in Wine, and also other ways to speed up the Windows build.

Biography: Jan is with since 2003, employed by SUSE/Novell. Previously he graduated from the Charles University, and worked as a YaST2 developer during the studies. His first experience with developing office software was back in 1998-9 when he programmed the drawing part of KTTV, a Linux word processor and a vector drawing program for lecture notes. In OOo, he focuses on KDE integration, x86-64 porting, build/SCM related problems, etc.

Handling insanity a sane way: Robust binary documents parser, strategies & tools

Strba, Fridrich (Software Engineer / TrainedMonkey / Novell, Inc. / Project)

Abstract: Office suites have to deal with a fair amount of binary data from untrusted sources. This kind of data and the code to parse it might be a source of security issues. This session would like to give the example of libwpd. How we managed -- after several security advisory -- to develop a strategy to code and test a robust parser that handles in a sane way even the most insane input data. This session will give an overview of our regression-testing framework as well as of tools that we use to try to tear the parser down.
