why colors don't exist
How do we see colors? What are colors? What's the correlation between wavelength and the colors we see? Do different people and species see colors differently? What would life look like without colors?

Why Are Doors Frustrating? | Good Design, Bad Design
Переглядів 743 роки тому
Design is more than just how an object or a product looks aesthetically, but it's primarily about the experience of using it. We interact with bad designs in our everyday life, and they sometimes affect our mood and make us frustrated. One aspect of the experience is discoverability. If we don't understand how to use something, then we are ought to feel frustrated and angry. Designers should un...

    Hi! I'm really enjoying the free Busuu version, I am using it for Italian. I want to use premium (mainly for the certificates...) but I see so many negative reviews online about payments being took even when the subscription has been cancelled. Have you had a good or bad experience with this? Grazie🙂

    • @charaf
      @charaf 3 роки тому

      Hi Ann, I haven’t had a bad experience personally. But I would say that the certificates don’t really matter as that most institutions don’t recognize that as a real certificate from my experience. Good luck on your learning journey.

      Congrats! Don’t worry about it, there are people from all over the world, most people I knew there weren’t from my home country as well. Now with the pandemic things might be different. Maybe check online for Serbians living in Qatar for example. It will feel weird at the beginning since it’s a totally different environment, but I think you’ll love it after getting used to the change.

    • @charaf
      @charaf 4 роки тому

      Right now you can’t travel directly there because of the conflicts (but you probably can with a transit or smth). As for the life there I would say that it’s been great, it even pushed qatar to do more things alone and you won’t feel anything really. Qatar even got the prize for the safest country this year as well.

      @charaf 4 роки тому

      No problem. I have friends that moved from Dubai to Qatar and they all say that they’re quite different. As you said Dubai is a very active place but Qatar (especially now) is more of a chill and calm place. Qatar is preparing to start getting tourists for the 2022 world cup so it might change then but from my experience it’s a calm place, there are places that you can visit and have fun of course but it’s not as much as Dubai. Hope that helps!

As for applying to jobs, I would suggest that you look for jobs online, the most popular in qatar are: qatarliving.com + qa.indeed.com + LinkedIn (and there other as well you can find them on google). If you cannot find your desired job there I would suggest that you search for the institutions that you want to work for and email them asking for details, companies usually respond to emails consistently.
