• Music Video Idiosyncrasies

  18 juin 2011, par Multimedia Mike — General

  So I’m watching a fairly recent music video for a song named "XXXO" from an artist named M.I.A. when I’m suddenly assaulted by this imagery :

  
  
  

  ... and I enter nervous convulsions. You see, while this might seem to be an odd video effect to the casual viewer, to a multimedia hacker, it appears to be deliberately antagonistic. To anyone who has written a video codec, this scene looks like an entire casserole of video bugs, combining creeping plane offsets errors, chroma problems, and interlacing havoc. The craziest part is to realize that this is probably some kind of standard video effect / filter type. Upon a repeat viewing, I realized that the entire video sort of looks like an amateur video editor’s first week using video software.

  Elsewhere in the video, a YouTube-style video frame vortex highlights the proceedings. I guess I need to come to terms with the fact that the ubiquitous player frame is just part of the digital Zeitgeist now :

  
  
  

  Vintage Video Strangeness
  I’m a long-time music video junkie but I have a tendency of examining them entirely too closely. I first saw Paula Abdul’s video for "Cold-Hearted" when I was just starting to understand multimedia technology and how it interacted with emerging home computers. Imagine how confused I was when I tried to make sense of the actions performed by our eMaestro "Chuck" whom Paula has instructed to "hit it". First, he hits a key followed by 3 quick strikes on a second key :

  
  
  

  Then, the "start music" action is apparently bound to a particular key on the electronic keyboard :
  
  

  
  
  

  Which kicks off the electronic metronome on the computer. Each identical-sounding beat quizzically maps to a different frequency transform :

  
  
  a one...
  
  and a two...
  
  and a three...
  

  I had no trouble believing things up to this point. But even though I didn’t understand what was going on with that frequency transform, I knew that it must have had something to do with the audio. And if the audio was the same, the visualization ought to be the same. Though, to be fair, I will concede that the first and third ticks pictured bear some mutual resemblance.

  Anyway, the software is probably real even if the keyboard interaction was stylized. Can anyone identify the software ? What about the computer ? This is perhaps the best view the video gives us :

  
  
  

  So, remember, don’t base your understanding of technology — or anything, really — on stylized media representations. Don’t even get me started on the movie "Sneakers." That had me confused about cryptography and computer security for many years.

• nomenclature #2549 : Renommer sommaire.html de façon plus explicite

  27 février 2012, par Fil Up

  on avait choisi sommaire pour plusieurs raisons négatives :

  index signifie "liste des fichiers"

  index.html à la racine risquait d’être servi quand on demandait la page "/" (c’est obsolète vu que c’est dans un sous-répertoire)

  "home" est en anglais s’il faut changer, accueil / accueil.html est (...)

  oui sur le principe de changer sommaire.html. Sur le nouveau nom, en revanche, je ne sais pas trop.

  home le pb de l’anglais. Pour un débutant SPIP, le fait d’avoir des noms français est appréciable.

  index, on retourne au même problème que sommaire.

  accueil, il y a un certains nombre de (...)
