Raspberry Pi- an example of its potential

Now, we haven't properly seen the Raspberry Pi's potential in a real situation, well an Article which is very recent, has showed us this. A student at Oxford University, successfully managed to put into place, a working and efficient system. Through months of coding on a raspberry Pi, Johan Paulsson had created an efficient day to day system. To put into perspective, a bar that previously had no idea about the quantity of its items, now has sales updates at 30 minute intervals, with the Raspberry Pi able to warn the bar when there is a staff shortage or item shortage. Paulsson has even managed to have  programmed the Raspberry Pi to detect temperature for health and safety
