Travel Quiz - Latin America   I've always been fascinated by Latin America: starting with the music, colors, traditions till its ancient history and amazing geography.      I wanted to create a big app to include interesting facts of this beautiful part of the world,  to have an educational side but also some travel tips and interactive content. This takes time and for a small developer it is important first the feedback of the app, so I launched it as a quiz.  After every question, it is shown a text with detailed info. I tried to cover historical things, from aztects, inca and maya times to scientific facts like how the water drain at Ecuator or where is the best place to see the Milky Way.           In the future, I want to add more info and also pictures of Latin America, from the beautiful nature of Brazil, to colored folkloric pattern in Peru, the wine from Argentina or Chile, irresistible music of Colombia or Venezuela and the most delicious food in the world in

The governors decide to pay for each head of cobra brought. Soon, the population of cobras decreased, but some people with entrepreneurial spirit started to raise in order to get money for their heads. When the governors found out(they wouldn’t like to waste money this way) put the new business men to release the cobras in the forest.

    The tragedy of jobs(not Steve)        Many times I saw on social media sarcastic photos about the persons that go to a job that could have it without graduating a college. Starting to my case, I will give some arguments why it is not a big tragedy to have that kind of job. Source:  https://pixabay.com/en/cashier-groceries-supermarket-store-1791106/ - Work is not a shame! Maybe that person didn’t find any job and couldn’t stay waiting. - Not everyone is going to collage because of a powerful wish, but a social pressure. It’s better to do something  you are comfortable with, than to be always behind other colleagues. - Actually it can be an opportunity for a great career, specially in big companies. I know persons that started as sale assistant and now they are the leaders in the company. - It’s a way to see how it is that work, that salary and how important is that you, as client, to not be the greatest jerk. - It can help to have a good discipline and resistance

What is machine learning? That's the first question in everything is new and the answer is exactly in the question: our brain needs to define, to classify, to compare and to anticipate the things around us in order to have a faster thinking. Machine learning is part of artificial intelligence and it can be translate as “learn how to learn” a computer or a device. I really like to compare machine learning with human thinking because I believe there's a lot of similarities. Once we see a thing/situation constantly, it remains in our memory and we can easily operate with it without trying to identify it again. For example, if we see a photo with the Tour Eiffel, we can easily say what it is, because all the media presented it many times and we already have it in mind(unless other touristic points that probably we saw it once and it's hard to recognize them). So it is with the machines: it can be made to recognize the Tour Eiffel, by giving it resources(photos) and the
