The avalanche beacon (typically known as ARVA in Europe: Appareil de Recherche de Victimes d´Avalanches) is an electronic device used to locate/be quickly located when trapped under a snow avalanche. Back in 2004 I presented an avalanche beacon rescue simulator as my Masther Thesis. The main goal was to try to better understand current rescue techniques, [...]
Also taggedEl ARVA (Appareil de Recherche de Victimes d´Avalanches) es un dispositivo electrónico que sirve para localizar/ser localizado rápidamente en una avalancha de nieve cuando realizamos actividades invernales con un grupo. En 2004 realicé como proyecto fin de carrera un simulador de rescates en avalanchas con ARVA, dentro de la titulación de ingeniería informática en la Universidad [...]

Abstracting to a higher level is always better for both the code writer and especially the code reader and maintainer. It also makes you focus on the problem you are solving. Optimization can be done later, if [...]

I did, they were just using “( )” instead [...]

There was still something not solved by the script: the ID3 tags of the MP3 files. id3lib, a [...]
