planear não é pilotar o Project
Posted by Armando Brito Mendes | Filed under materiais para profissionais, planeamento
Interessante texto sobre o q significa planear
Planejar não é pilotar o Project (ou qualquer outro software de planejamento)… atualmente há diversos softwares de planejamento, com diferentes níveis de detalhes e possibilidades. Aprender a utilizar estes softwares não é tão difícil (pelo menos o básico), porém é preciso entender que estes softwares são uma ferramenta de planejamento, não são O Planejamento.

Uso de algorimtos de visinho mais próximo para visualizar semelhanças
North Carolina State statistics graduate student Joshua Katz already mapped dialect across the United States, and now there’s a fun addition in quiz form. Answer the 25-question survey (or the more detailed 140-question version if you dare), and you get a map of language similarity. More specifically, the result maps shows the probability that someone in that area understands what you’re saying.

Excel: Esconder valores duplicados
Posted by Armando Brito Mendes | Filed under materiais para profissionais, software
Tip para esconder valores repetidos usando formatação condicional
Duplicate values aren’t wrong or bad, but they can be distracting. You probably won’t want to delete them, but you might just want to hide them. For example, the simple sheet below repeats date values in column A. In a reporting scenario, those duplicate dates might be annoying.

Visualization archives on FlowingData
Posted by Armando Brito Mendes | Filed under visualização
Os arquivos de artigos sobre visualização de dados
Download data from a site of interest and learn all you can about it. Analyze, try to answer your own curiosities, and of course, visualize it. Try to apply what you’ve learned from the books and tutorials to your own data. And I’m not gonna lie: It might be rough at first and maybe frustrating, but you’ll get there.
I gathered some resources a few years ago on where to find data. Some of the sites are dead now, but it should give you a good idea of where to get some spreadsheets and CSV files. If you’re lucky, you might find data sources in PDF format. Have fun with that.
After that, download R, mess around with a trial version of Tableau, get your Data-Driven Documents on, or even try to push Excel to the limit.
If you’re still not sure where to begin, find a visualization you like and try to reproduce it. If it’s a good one, you’ll probably discover that making the graphic is a lot harder than you expected. Totally normal. The FlowingData archive provides plenty of examples.

A site from two data scientists
Taking a step away from books, academic papers are another great resource, which often gets overlooked. The great part is that most people put their published papers online these days, in non-walled spaces. Some papers are too technical and use a lot of jargon, but there are many good (practical) ones to learn from.
For example, Jeffrey Heer and his students from Stanford produce fine papers. Fernanda Viegas and Martin Wattenberg, both now at Google, wrote applicable papers back when they were at IBM.
