Computer Science Education: It’s Not Shop Class

2010/01/30

“As I noted in an article Monday, the National Science Foundation wants to reform high school computer science education in America, expanding its reach and updating the curriculum to better prepare students for a 21st-century economy.
(…)
The N.S.F. seems to have a sound strategy for elevating computer science education in high schools by collectively raising its sights. Across the board, the approach is less emphasis on the digital equivalent of shop classes — how to use PowerPoint and Excel, or do Java programming. Instead, the goal is to “teach them the magic of computing,” said Janice Cuny, program director of the foundation”

Picture-driven computing

2010/01/25

“When I saw that, I thought, ‘Oh my God, you can do that?’” says Allen Cypher, a researcher at IBM’s Almaden Research Center who specializes in human-computer interactions. “I certainly never thought that you could do anything like that. Not only do they do it; they do it well. It’s already practical. I want to use it right away to do things I couldn’t do before.”

Receita de Ano Novo

Receita de ano novo

Para você ganhar belíssimo Ano Novo
cor do arco-íris, ou da cor da sua paz,
Ano Novo sem comparação com todo o tempo já vivido
(mal vivido talvez ou sem sentido)
para você ganhar um ano
não apenas pintado de novo, remendado às carreiras,
mas novo nas sementinhas do vir-a-ser;
novo
até no coração das coisas menos percebidas
(a começar pelo seu interior)
novo, espontâneo, que de tão perfeito nem se nota,
mas com ele se come, se passeia,
se ama, se compreende, se trabalha,
você não precisa beber champanha ou qualquer outra birita,
não precisa expedir nem receber mensagens
(planta recebe mensagens?
passa telegramas?)

Não precisa
fazer lista de boas intenções
para arquivá-las na gaveta.
Não precisa chorar arrependido
pelas besteiras consumidas
nem parvamente acreditar
que por decreto de esperança
a partir de janeiro as coisas mudem
e seja tudo claridade, recompensa,
justiça entre os homens e as nações,
liberdade com cheiro e gosto de pão matinal,
direitos respeitados, começando
pelo direito augusto de viver.

Para ganhar um Ano Novo
que mereça este nome,
você, meu caro, tem de merecê-lo,
tem de fazê-lo novo, eu sei que não é fácil,
mas tente, experimente, consciente.
É dentro de você que o Ano Novo
cochila e espera desde sempre.
