An Antic Disposition: Math markup marked down

The following is an open-letter addressed to the portuguese comittee responsible to evaluate Microsoft's proposal of turning OOXML as an ISO. They are going to debate tomorrow the issue and take a decision. Problem is that one of the members of the comittee works for Microsoft-Portugal. This will probably have a negative impact on the fairness of the decision but I'm only speculating. So I wrote this letter addressing the committee and politely asking them to revogue OOXML to become an ISO. I hope OOXML looses. I really favor ODF. OOXML is proprietary and mocks everything that was already designed by the open-source community such as MathML and the ODF format (which is the OpenOffice format).


Caros senhores da comissão,

Devo apresentar-me, se me permitem. Sou Guillaume Riflet, licenciado em engenharia física tecnológica e, presentemente, aluno de doutoramento em engenharia do Ambiente no Técnico. A minha tese consiste em implementar um modelo de previsão de correntes marítimas para a costa Portuguesa de modo operacional. Como podem imaginar, passo grande parte do meu tempo ocupado a lidar com computadores. Por outro lado sou igualmente um entusiasta do Web2.0 e da sua cultura e já fiz apresentações do tema para a Aksen e a Generator, empresas de soluções web e de e-marketing respectivamente (http://www.slideshare.net/griflet/web-20-47985).

No âmbito do meu trabalho tenho que submeter frequentemente artigos para revistas e conferências da especialidade. Como processador de texto científico uso preferencialmente o Latex, mas ocasionalmente também uso o ms-office ou o openoffice. Pode-se dizer que os meus interesses sobre uma norma ISO de documentos são representativos dos interesses da comunidade científica nacional e internacional.

E em nome do interesse da comunidade científica devo apresentar algumas críticas à norma OOXML:

1 - Do ano 2000 para cá, a comunidade científica internacional tem vindo a desenvolver o MathML, um esquema XML para formulação simbólica de equações matemáticas. O MathML é o esquema XML mais repandido e usado na internet para linguagem matemática simbólica. O OOXML simplesmente não considera o MathML. Isso é uma falha grave. O OOXML deve pelo menos reconhecer a existência do MathML e justificar se o seu esquema de XML para texto matemático é vantajoso sobre o MathML. Por causa desta falha, revistas de grande relevo internacional como a Science e a Nature recusam documentos no formato .docx (http://www.robweir.com/blog/2007/04/math-markup-marked-down.html). Infelizmente, muitos colegas científicos recorrem ao ms-word para submeter artigos a revistas e a conferências por ser-lhes mais conveniente. Vêem-se assim obrigados a recorrer a processadores de texto caducos para submeterem artigos de conteúdo científico de ponta o que representa para eles na prática uma perda na produtividade ciêntifica, e representa para Portugal trabalhos submetidos com menor qualidade gráfica.

2 - O ODF é um esquema de XML de documentos de tipo Office que é livre. É hoje um standard, reconhecido por entidades de relevo na área como a OASIS. O ODF é o esquema utilizado pelo OpenOffice, a suite open-source homóloga ao ms-office. O OOXML deve reconhecer a existência do ODF e justificar quais as suas vantagens em relação ao mesmo para ser seriamente considerado como Standard alternativo na matéria.

3 - O OOXML é uma norma que é propriedade da Microsoft. Em nome da defesa dos "consumidores" das ISOs deve-se privilegiar, quando disponível, normas livres. Neste caso existe a norma ODF que é livre e que já tem uma larga aceitação e utilização pela comunidade ciêntífica internacional.

Para qualquer revisor ciêntífico, um artigo que não apresente um state-of-the-art e que não demonstre um trabalho original E inovador será sistematicamente revogado. Por todas estas razões, a proposta da norma OOXML não apresenta um estudo sério do estado da arte (MathML, ODF) e não se revela nem original, nem inovadora (ODF), e portanto não serve os interesses da comunidade científica quer nacional, quer internacional. Proponho assim que se revogue a proposta da norma OOXML, propriedade da Microsoft, para ISO de documentos de tipo Office.

Com os meus melhores cumprimentos,
Guillaume Riflet

Back in 2005 I was really excited about the web2.0 concepts, the web-based APIs, mashups, and all the new publishing tools that was later to be known by 2008 as "social-media".
Somebody wrote a while ago:

Google is an advertising company that builds popular services that command large audiences.

To which I add:

Apple is a leisure company that builds popular media-platforms that command large audiences of media-consumers.
I just got accepted to the most awesome workshop in the whole world, organized right here in Lisbon, the Codebits 2010, promoted by sapo.pt,

I'll be staying three days, in a row, in a big room packed with free wifi and free cable net access, unlimited free pizza, free cokes, free chocolate bars and
One of the biggest pain in the butt after an exciting conference/workshop/meeting is inputing all your fresh new contacts business cards info into your digital mail/phonebook. This is a problem. An unsolved one too.
Android is for tasks, life-hacks, body-hacks, and Chrome is for organized data, information.

At some point in the foreseeable future I expect to see an elegant merger where a next-gen browser will be the sole platform.
Hello all, it's been a while since my last post. These last months were spent mostly dedicated to finish my unfinished thesis - Ever heard of PhD comics? No? Well, it works better than Dilbert for me. Here's a nice one ...
The ipad is probably more expensive than the Chrome OS... but the browser experience is better, much better. I'm bending towards buying an iPad for my mom, so that she'll start using a computer, finally! She bought a laptop because she wanted to get in touch with her kids and friends through gmail.
My mom sure could use one of those Google PCs.

She's a veteran school teacher. She doesn't like using computers and hates the fact that she has to configure them for the wifi connection.

When I first started this blog, I wanted to make a statement about my vision regarding the future of computing. I called this new thing the webtop. That was back in 2006.
Hi, I'm testing a javascript based syntax highlighter for this blog.
Google just launched earlier this week the new google mobile app with voice search. Now, we always went extatic in this blog, whenever a new web-based app with text-to-voice or voice-to-text features would come around.
Last week I went to codebits, the 24/3 hackers contest organized by the portal sapo.pt. And it was awesome! I had loads of fun, learned tons of stuff, met a bunch of new and interesting people, worked on my tech social network, etc, etc...
Last week I went to Shift.pt, a conference about new technologies, society and the web, organized and sponsored by Sapo.pt. There I've acquainted a bit more with Pedro Custódio and his team/friends, as well as a whole new bunch of very interesting people.
Here's an excerpt of a mail (addressee anonymacy kept) I wrote today that tells a long way about what are my expectations on shift, the web2.0 and society conference happening in Lisbon the 15th, 16th and 17th October 2008.

One of the interesting things about web-wired mobile devices, is the ability to quickly geolocate the user, either by GPS, either by cell-tower antenna id, either by networked wifi ip.
Google just launched today their new open-source browser called Chrome. They're now adding a new element to the browser wars along with IE, Mozilla Firefox, Safari and Opera. This is a really smart move from Google towards building their Google OS.
Evernote is an interesting web service that stores all your notes, audio-notes, and snapshots and archives them for you. It then allows you to perform text search on them, even inside images.
In this post I will show you how to subscribe to twitter to receive free sms alerts on your cell phone. You can receive live soccer goals, weather forecasts, traffic alerts, the IST canteen menu, you name it ...
