Electronic Travel Authority

harvesting has a long history in the Matmata Plateau, where climate, topography and soils together make the technique very effective. The majority of rain falls as high intensity-low frequency downpours. Overland flow is generated rapidly and it travels quickly over the steep slopes, supplying water and soil to valley bottoms. Earthen check dams (tabias) are sited progressively downslope to trap eroded material from the valley sides and this material is levelled to form agricultural fields (jessour)

moindres que celles attendues. En 1 9 6 9 Bell Labs se retire du projet pour se tourner vers le développement d’un autre système appelé GECOS. Ken Thompson, développeur chez Bell, continue cependant à travailler sur le GE-645 et écrit un jeu appelé Space Travel. Tournant avec Multics il se révèle très lent et coûteux à faire tourner en temps partagé (avant le multitâche, le temps de la machine était découpé en tranches et chaque tranche d’utilisation était décomptée et facturée). - 4- © ENI Editions
