“Collaboration has become an integral aspect of
software engineering. The widespread availability and adoption
of social channels has led to a culture where today’s developers
participate and collaborate more frequently with one another.
Awareness is widely accepted as an important feature of collaboration,
but exactly what this encompasses and how processes and
tools should be evaluated in terms of their awareness support
remains an open challenge. In this paper, we borrow a theory of
regulation from the Learning Science domain and show how this
theory can be used to provide more detailed insights into how
collaboration tools and processes can be compared and analyzed“

Software developers rely on media to communicate, learn, collaborate, and coordinate with others. Recently, social media has dramatically changed the landscape of software engineering, challenging some old assumptions about how developers learn and work with one another. We see the rise of the social programmer who actively participates in online communities and openly contributes to the creation of a large body of crowdsourced socio-technical content.

Accelerating you academic career and publishing in top journals

Talk given by professor Ian Hodgkinson at UTFPR Curitiba today (August 22nd, 2018).

Main takeaways

You must have a Research Pipeline.  The aim is to always have something under review. You will reap rewards from your current effort in 2 a 6 years. Don't expect immediate gratification. Submit to a mixture of mid-range and high-end journals.

Visualize you ideas to keep focus. Have something like a Kanban board (at your office or at home) displaying your research ideas.

Profile Building. Besides going to conferences and workshops,  have a profile on Academia, Research Gate and Google Scholar.

Do some research related activity everyday (except weekends) for at least 20 minutes.

Keep your CV up-to-date.

Read the Introduction from papers published in the best journals of your area. Imitate how they do that.

My  handwritten notes are here. The image below is the first page.

O Nascimento da Refatoração, de Willam Griswold e William Opdyke

Um paper (ver abaixo) num formato raro, contando a estória do desenvolvimento das pesquisas que levaram ao desenvolvimento da Refatoração, com dicas para aqueles que querem um dia "criar" (oi "nomear e definir", o que parece ter sido mais o caso) algo que tenha tanto impacto quanto  a Refatoração.

Alguns detalhes:

• A Refatoração foi  criada de forma independente por dois estudantes de Doutorado. E isso não foi um problema. Os dois conseguiram defender suas teses. Até ajudou a convencer de que o assunto era relevante.
• Um dos desenvolvedores era apenas um estudante. O outro um profissional do mercado que decidiu fazer Doutorado.
• "Tools are important to software engineering research".  Ajuda bastante construir uma ferramenta para representar sua ideia.
• Apesar de todo o sucesso, as interfaces das ferramentas de refatoração são consideradas difíceis de aprender. 
• Nunca ninguém irá reclamar se você mencionar Fred Brooks ou Tony Hoare.

The Birth of Refactoring: A Retrospective on the Nature of High-Impact Software Engineering Research

Griswold, William G. ; University of California, San Diego ; Opdyke, William F.

IEEE Software

Software refactoring was independently invented in the late '80s by two students in two research groups: Ralph Johnson's group at the University of Illinois and David Notkin's group at the University of Washington. This article provides a retrospective of the birth of refactoring, reflecting on how the ideas came about and were developed in those two students' doctoral dissertations. The analysis provides useful insights for both researchers and practitioners seeking high impact in their work. This article is part of a special issue on Refactoring.

Todos eles estão acima da mediana da área e portanto são ótimos locais para publicação.

TDD: Adequate Training

From "The Effects of Test-Driven Development on External Quality and Productivity: A Meta-Analysis", by  Y. Rafique and V.B. Misic (Ryerson University, Toronto, Canada):

"We note a few key issues that the authors of future empirical studies should be aware of when designing their experiments. Adequate training should be given to the subjects so that they can sufficiently grasp the TDD technique prior to the actual experiment. Detailed information about training should be provided as well, including specific areas as well as the duration of the training."

Does this mean that TDD is too difficult to learn?

Medição de "Felicidade" no Twitter

Através deste comentário no blog Recorrido, do Danilo Balu:

Fiquei conhecendo este site: Hedonometer

Imagem gerada pelo Hedonometer

Trata-se de um trabalho de pesquisa, já com algumas publicações, inclusive três na PLoS One.

Vale a pena ler os artigos para conhecer o algoritmo que utilizam, que os levou a concluir que:

The saddest day of them all was the date of the Boston Marathon bombings, with a happiness score of 5.88 on a scale of 1 to 9. But even though it had less-sad score, Dec. 14, 2012, the date of the mass shooting at a Newtown, Conn., elementary school, may have actually been sadder, Danforth said.

That’s because the Newtown shooting happened on a Friday, a generally happy day when people otherwise would be tweeting positive vibes, he said. The Boston bombings happened on a Monday, when unrelated grouchy tweets about returning to work would have driven the average happiness down.

Mandei o link para um colega que escreveu:

Na verdade, fazendo uma análise on-the-fly, isso mostra os visos de
manipulação das novidades na web.
Acho que muito mais triste devem ter sido os acontecimentos na Europa com
todos os golpes sucessivos nas populações, fora as sucessivas crises de
final de ano nos EUA...gostaria de ver esse algoritmo

Ao que respondi:

Só acho que pode não ser manipulação.
A questão é que tem mais internautas nos EUA do que na Europa.
E tudo que afeta os EUA afeta Europa e resto do mundo.

Eu mesmo tuitei várias coisas tristes quando dos atentados em Boston.
Devo ter tuitado muito menos sobre os golpes na Europa pois:
 - não eram questões pessoais e sim populacionais
 - crises econômicas não tocam tanto.

Tem uma análise disso num dos livros do Nassim Nicholas Taleb. Ele conta que estava acontecendo uma Guerra Civil no país dele (atualmente chamado Líbano) mas que as
pessoas estavam mais preocupadas com o resgate de um menino que caiu num poço na
Itália. O menino era capa de jornais no Líbano! Ele acabou sendo salvo após vários dias.


Aqui você pode ler o texto: http://chennaikaran.blogspot.com.br/2007/07/boy-in-well.html

E você, o que acha? Os desastres nos EUA são mais tristes por conta de manipulação da mídia?

Mais sobre a Avaliação da Pesquisa no Brasil

Somente hoje vi que o texto "Um novo modelo de avaliação dos programas de pós-graduação a ser enviado à CAPES", do professor Otavio Carpinteiro (UNIFEI), foi publicado no Jornal da Ciência em 13/03/2013. Este texto está relacionado a um post anterior deste blog: Sobre a Avaliação (errada?) da Pesquisa no Brasil.

O professor Luis Paulo Vieira Braga (UFRJ) comentou o texto do professor Otavio em CAPES: Avaliação ou Afiliação?. Alguns trechos:

Como a avaliação é essencialmente baseada na produção absoluta de artigos no topo da escala Qualis, o sistema apenas renova as notas elevadas dos mesmos cursos consolidados, deixando na rabeira os grupos menores ou novos. 

Os dados apontam sucesso no número de artigos, mas quando se trata de citações, patentes, prêmios e descobertas relevantes a contribuição brasileira deixa a desejar.

Eu acho que o nosso sistema de avaliação da pós-graduação está errado e precisa ser rediscutido. E você, o que acha?
