Just a quick announce of a pet project I started a few months ago. Unfortunately I've already slowed down work to a halt as I focus on finishing my MBA dissertation.
The objective of the Metadata Flask project is to provide tools for supporting the process of finding, collaborating and working with metadata on an open and linked-data web.
Nowadays when players of an industry vertical, say: commodities producers and large scale retailers like Walmart, or Oil & Gas equipment producers and Oil companies/operators want to define and evolve data exchange formats they have to build their own infrastructure for documenting, referencing and hosting data exchange definitions.
These players frequently need to exchange a lot of data for describing what is produced, their specs, how they are sold, who wants to buy etc. So they come up with metadata definitions like WSDL contracts, XML schemas, CSV/JSON templates and so on.
I believe their work would be a lot easier if infrastructure for hosting, exchanging, discovering, collaborative editing, moderating and many other metadata related processes was already in place.
The goal is ambitious, the problem not well defined and "tractable" right now, so I started investigating what open data sets are available out there. What I realized is that many of them couldn't be found using general purpose search engines, so I started a first subproject, the Open Data Directory, which is a search engine for open data sets published by governments, private companies and other organizations. It already indexes 360K+ datasets from many sources, and traffic is slowly increasing as search engine bots index its contents.

Pet project: Metadata Flask
I wish Amazon would innovate faster on it's Kindle OS
- Social features: why stop at public note sharing via twitter/facebook? Why not integrating to services like Evernote, Instapaper, Delicious? Why can't it sync my notes to Amazon's website? It would be nice to be able to review them online.
- Notes/highlights usability: The reading experience should be at least as powerful as the Real Thing. Why can't I attach notes to whole chapters or even books? Why restrict it to contiguous blocks of text? After all, the whole reading experience is mostly not about what I read, but what I thought about it, what I learned from it, how it applies to me, and people use notes for remembering these things.
- Podcasts: it has enough storage and CPU for playing mp3s and downloading data on the background. Why not scheduling the download and managing podcasts?
- Improve the experience for reading blogs. Why not integrating to Google Reader?

Of course it's hard to compete with Malcom Gladwell

Comentários sobre o Kindle 2 (Internacional) no Brasil
ATUALIZAÇÃO 28/DEZ/2010: Comprei um Kindle 3a. geração (o de cor grafite). Vantagens confirmadas em relação à 2a. geração (cor branca): realmente muito mais rápido, contraste da tela melhor, dimensões e peso bem mais confortáveis. É todo de plástico, dando uma sensação de ser menos resistente, enquanto que o da 2a. geração tem uma placa de metal leve nas costas. De qualquer forma continuo achando que todas as versões de Kindle são frágeis e não resistiriam a uma queda pequena: nada fundamental mudou na tecnologia da tela então acredito que elacontinua sendo o ponto mais frágil.

Image search code from imgSeek ported to the Xapian search library
Similar to what digiKam did, the Xapian opensource search engine library has also ported imgSeek code into its code base in order to provide content-based visual search features.

Quick note for Nokia owners trying to upgrade the firmware under VMWare/Parallels
Avoid doing it under virtual machines. Nokia's firmware update system restarts the cell phone dozens of times as part of the upgrade process so the host and virtual machine will get all confused and as soon as the host machine refuses to "forward" a USB connection to the hosted OS, the upgrade process will stop due to a disconnection. This may cause severe damage to your cell phone (taking it back to a Nokia care center could be the only way out, so they can "re-flash" your phone ROM).
When trying to upgrade my E71 to the latest v200.21.118 firmware using Parallels under OSx I got one such aborted process, but luckily it worked flawlessly when trying again with a real Windows XP.
Other quick tips:
- Backup all cellphone data and check if your backup works before the whole process. Using "Tools -> Memory -> Options -> Backup phone memory" from within the phone worked fine;
- Remove the microSD card before the process, just to be sure;
- Avoid doing it under Windows Vista, as some have reported similar problems.

Nokia E71 adoption
Interesting statistics from Flickr: Nokia E71 adoption seems to be increasing faster than any other previous model.
