Python introduktion

October 15, 2008

This post is in danish. Sorry …

For et par år siden skrev jeg en introduktion til Python rettet mod folk med kendskab til imperative sprog. Vi var et par stykker der skulle lære sproget og jeg satte mig for at lave en række repræsentative opgaver. Introduktionen er derfor opbygget som et (fiktivt) kursus. Følgende områder berøres:

  • Hello, World
  • Arrays (kaldet lister i python)
  • Filer og strenge
  • Hashes (kaldet dictionaries i python)
  • Objekter
  • Moduler
  • CGI
  • .NET
  • Client/Server

De afsluttende opgaver bærer præg af, at jeg skulle finde på nogle ekstra opgaver uden – på forhånd – at kende deres svar.

This site offers printable lens hoods in PDF format. They are clearly not as nice as real hoods, but they do the trick.

Ken Rockwell facts

October 13, 2008

There’s a thread at DPReview listing a few lesser known facts about Ken Rockwell. A few picks:

  • Ken Rockwell doesn’t adjust his DOF, he changes space-time.
  • Ken Rockwell doesn’t wait for the light when he shoots a landscape – the light waits for him.
  • Ken Rockwell ordered an L-lens from Nikon, and got one.
  • When Ken Rockwell brackets a shot, the three versions of the photo win first place in three different categories.
  • Ken Rockwell doesn’t use flash ever since the Nagasaki incident.
  • Only Ken Rockwell can take pictures of Ken Rockwell; everyone else would just get their film overexposed by the light of his genius.
  • Ken Rockwell’s nudes were fully clothed at the time of exposure.
  • On Ken Rockwell’s desktop, the Trash Icon is really a link to National Geographic Magazine.
  • For every 10 shots that Ken Rockwell takes, 11 are keepers.
  • Ken Rockwell’s digital files consist of 0’s, 1’s AND 2’s.
  • Ken Rockwell never focus, everything moves into his DoF.
  • Ken Rockwell isn’t the Chuck Norris of photography; Chuck Norris is the Ken Rockwell of martial arts.

This – of course – is a pun on the well known Chuck Norris facts.
