John Carmack and simplicity

I've re-read John Carmack's famous .plan file (http://www.bluesnews.com/archives/carmack122396.html). It compares Direct3D to openGL in 1996. It was the beginning of hardware accelerated 3D graphic cards. John explains the differences between the simple, procedural openGl glBegin (GL_TRIANGLES); glVertex (0,0,0); glVertex (1,1,0); glVertex (2,0,0); glEnd (); and the ugly Direct3D (incomplete!) equivalent v = &buffer.vertexes[0]; v->x = 0; v->y = 0; v->z = 0; v++; v->x = 1; v->y = 1; v->z = 0; v++; v->x = 2; v->y = 0; v->z = 0; c = &buffer.commands; c->operation = DRAW_TRIANGLE; c->vertexes[0] = 0; c->vertexes[1] = 1; c->vertexes[2] = 2; IssueExecuteBuffer (buffer); You read this, and you feel confortable you have bet on the right horses (Drupal for example, or jquery, or extJs in the webapplication realm) and you stay away of the ugly beasts (I won't cite them, they will recognize themselves). KISS

L'histoire du papier électronique

Je pense depuis longtemps que le papier électronique va révolutionner la façon dont nous consommons de l'information. Patience patience... En attendant son arrivée massive, voici un historique de la question "I like to tell people that the holy grail of e-paper will be embodied as a cylindrical tube, about 1 centimeter in diameter and 15 to 20 centimeters long, that a person can comfortably carry in his or her pocket. The tube will contain a tightly rolled sheet of e-paper that can be spooled out of a slit in the tube as a flat sheet, for reading, and stored again at the touch of a button. Information will be downloaded—there will be simple user interface—from an overhead satellite, a cell phone network, or an internal memory chip. This document reader will be used for e-mail, the Internet, books downloaded from a global digital library that is currently under construction, technical manuals, newspapers (perhaps in larger format), magazines, and so forth, anywhere on the planet. It will cost less than $100, and nearly everyone will have one!" http://www.tfot.info/articles/1000/the-future-of-electronic-paper.html

Le lecteur flash va bientôt lire les fichiers mp4 - youtube en qualité HD

Le lecteur flash (disponible en bientôt en version 9.x beta) va permettre de lire des fichiers mp4 (h.264) directement, en plus des fichiers flv. Le format h.264 n'est pas propriétaire (des solutions open source existent) et permet une excellente qualité de lecture pour une taille modérée de fichiers vidéos. Ceci devrait booster la vidéo sur internet. Les sites comme youtube attendent avec impatience ce nouveau lecteur qui devrait réduire leur facture de bande passante (les fichiers mp4 sont plus légers que les .flv à qualité équivalente) Toutes les infos techniques sur : http://www.kaourantin.net/2007/08/what-just-happened-to-video-on-web_20.html
