What is Good design and Great design?

Following the lovely course on design from iversity iversity.org/courses/design-101-or-design-basics I've come across the following statement

Playing a Graphic Designer a.k.a Making a banner and youtube logo to a friend

I've been playing around in Illustrator and Photoshop, messing with some types, alignments and images to try to make something useful for a great friend.

That's the result, I hope you like it!

I didn't have the guts with typography contrast here, making "essa" and "vamos" a little boring. 

This one is completely different, a less ludic approach.

Workshop Desenvolvendo Space Invaders com o Flex SDK - UCL

Eu e meu amigo Vitor de Azevedo demos um workshop de três horas na UCL com o título: "Desenvolvendo Space Invaders com o Flex SDK". Como eu prometi, aqui estão os slides e os códigos exemplo

• Slides (PDF)
• Exemplo (zip do projeto)

Downloading all links from a page

You can use the best part of two worlds (Javascript and Python) to rapidly download all the links from a page. As an example, I'm download all the files from this page http://www.inf.ufes.br/~alberto/proc-par/index.html

First, using chrome, open the Developer Console (Ctrl+Shift+J), now click in Console.

Now, using some js do:

links = document.getElementsByTagName('a');
for(var i=0;i<links.length;i++) { console.log(links[i].href); }


And you should get something like this:
http://www.inf.ufes.br/~alberto/proc-par/programa_processamento_paralelo-2012-1.doc
http://www.inf.ufes.br/~alberto/proc-par/Lista_de_Exercicios_de_Processamento_Paralelo.doc
http://www.inf.ufes.br/~alberto/proc-par/Lista_de_Exercicios_de_Processamento_Paralelo2.doc
http://www.inf.ufes.br/~alberto/proc-par/avaliacao_da_aprendizagem-mestrado.doc
http://www.inf.ufes.br/~alberto/proc-par/aula1.doc
http://www.inf.ufes.br/~alberto/proc-par/aula2.doc
http://www.inf.ufes.br/~alberto/proc-par/aula3.doc
...

Copy and paste it into a python file:

links = """
And you should get something like this:
http://www.inf.ufes.br/~alberto/proc-par/programa_processamento_paralelo-2012-1.doc
http://www.inf.ufes.br/~alberto/proc-par/Lista_de_Exercicios_de_Processamento_Paralelo.doc

http://www.inf.ufes.br/~alberto/proc-par/avaliacao_da_aprendizagem-mestrado.doc
http://www.inf.ufes.br/~alberto/proc-par/aula1.doc
http://www.inf.ufes.br/~alberto/proc-par/aula2.doc
http://www.inf.ufes.br/~alberto/proc-par/aula3.doc
....
"""

# Finally download the files

import urllib
links = page.split()
for link in links:
   filename = link.split('/')[-1]
   print 'downloading', filename
   urllib.urlretrieve(link, filename)

Result:
