Une expérimentation hasardeuse pour traduire des images de webcam
|
C'est une expérimentation hasardeuse pour traduire des images de webcam
|
||||||
en sons qui déchirent les oreilles, mais qui sont bio-dégradables.
|
en sons qui déchirent les oreilles, mais qui sont relativement
|
||||||
|
inoffensifs.
|
||||||
|
|
||||||
|
Pour le moment, il n'y a pas de procédure d'installation, il faut
|
||||||
|
donc lancer le binaire à partir du répertoire de dèv :
|
||||||
|
`~/Devel/DD2-monitor/Beep/alguabeep [options]`, ce qui implique
|
||||||
|
de ne pas aller mettre la grouille dans ce coin-là.
|
||||||
|
|
||||||
|
Ensuite, pour apprécier pleinement la kitchitude (assumée) de l'affichage
|
||||||
|
numérique de la machinerie en action, il faut un `xterm` en 150 caractères
|
||||||
|
de large, et une toute petite fonte.
