It was a preoccupation of the Greeks and Arabs (in the period between about 300 BC and about 1200 AD) to keep accurate track of time. In Ptolemaic Egypt, about 270 BC, Ctesibius described a float regulator for a water clock, a device not unlike the ball and cock in a modern flush toilet. This was the earliest feedback controlled mechanism.[11] The appearance of the mechanical clock in the 14th century made the water clock and its feedback control system obsolete.

C'est peut être toujours pas très claire donc je vais vous donné un exemple ! Sur facebook il y a souvent des groupes de revente de place de concert (quand les événements sont complet par exemple), le seul soucis c'est qu'a moins d’être derrière son ordi toute la journée généralement quand quelqu'un vend sa place 5 min après elle est déjà vendu et t'es passé sous le nez ...

…the line of code is highlighted in the Firebug console (I added the red box around the ID). The image above reminds us a webpage is organized in a nested, tree-like structure, starting with .document as the root object and branching out from there into smaller objects. This is called the Document Object Model. .getElementById("__") is the go-to tool for grabbing one of those objects from the webpage. With it you can scrape data from a page, as well as writing to a webpage as we’re doing here. Here’s a sneak peak at some other ways we could have found the search box and entered data into it (shown in the order I would have tried them, if an ID was not available).
When you execute the script below, if function is JavaScript it will execute, if not it will find function you load from Web Browser, example function go, it not function JavaScript so that function will call, then window.external.go(url) will communicate with window application by ObjectForScripting and run function go(string url) and it will show dialog with message is 'http://www.google.com';
Based on a formula by Gilles Saint-Paul, an economist at Toulouse 1 University, the demand for unskilled human capital declines at a slower rate than the demand for skilled human capital increases.[100] In the long run and for society as a whole it has led to cheaper products, lower average work hours, and new industries forming (i.e., robotics industries, computer industries, design industries). These new industries provide many high salary skill based jobs to the economy. By 2030, between 3 and 14 percent of the global workforce will be forced to switch job categories due to automation eliminating jobs in an entire sector. While the number of jobs lost to automation are often offset by jobs gained from technological advances, the same type of job lost is not the same one replaced and that leading to increasing unemployment in the lower-middle class. This occurs largely in the US and developed countries where technological advances contribute to higher demand for high skilled labor but demand for middle wage labor continues to fall. Economists call this trend “income polarization” where unskilled labor wages are driven down and skilled labor is driven up and it is predicted to continue in developed economies.[101]
Pour le cas des tests Cooperons! les problématiques rencontrées sont les mêmes décrites au début de l’article en plus d’une autre particularité : On a besoin d’effectuer des mises en production fréquentes et livrer de nouvelles releases sur des intervalles rapprochés (parfois d’une façon hebdomadaire). Sachant que l’exécution de tout le cahier de test est effectuée par 3 testeurs/développeurs et nécessite entre 4 et 5 jours pour être finalisée. On a fini avec des deadlines non respectés et un processus de test plus lent et moins fiable. L’automatisation s’impose dans un tel cas. Les résultats obtenus sur Coopérons! grâce à l’automatisation ont permis de :
cents ans. Mais les outils numériques peuvent influencer leur mise en œuvre. Par exemple, pouvoir fournir immédiatement un retour pertinent à un élève lors de la réalisation d’une série d’exercices peut favoriser le processus d’automatisation. De même, pour comprendre un phénomène dynamique complexe (comme le galop du cheval), le fait de pouvoir […] Lire la suite☛ http://www.universalis.fr/encyclopedie/apprentissage-avec-le-numerique/#i_2513
