We present today the list of the most visited websites in the world :
Unsurprisingly, the most popular site is Google. But be careful, the numbers do not always have the value that is expected of them. For example, in this list, numbers 1 and 2 are Google and Youtube. But these two companies are part of the same company: Google LLC. So, Facebook has to be compared to Youtube and Google together, the first place in the ranking, far ahead of others.
Beware of Wikipedia which is in 5th position, but most of the traffic comes from questions asked on Google.
Interestingly, we can also note that US companies dominate this ranking. But the Chinese are not absent, even if they do not occupy the first places.
The first site is Baidu, a Chinese search engine in 4th position. But we also have QQ in 9th position, and plenty others companies. Note that the second social network after Facebook is Twitter in just 11th position, and the third is Instagram, in just 14th position.

First of all, drones can do a lot of things that were not possible thanks to the miniaturization of electronic components. They are often equipped with high definition cameras. But they can do many other things. They can :
- send flames
- send insecticide to destroy Asian wasp or hornet nests
- carry packages as for the Amazon company
- carry people like Airbus
- and lots of other properties
They can also simply be equipped with light of all colors.
Another property is very interesting: the flight of drones can be controlled by distance, and directed through a computer program. As a result, they can very accurately coordinate their flight not related to each other and perform an overall flight.
So we begin to see shows of hundreds, and sometimes thousands of drones with fairies of color and movement in the dark sky.
What are the benefits of these shows compared to conventional fireworks?
- Less noise, even if the flight of drones is not perfectly silent.
- Indeed, fireworks often frighten birds and some die
- An infinity of figures in the sky, computer programs being unlimited
- Better environmental protection because more particles are released into nature with fireworks
On the other hand, it is necessary to regulate the risk of falling of a drone on spectators. The obvious solution is to make these shows over risk-free areas: lake, river, mountain, …
