12. Inimese ja arvuti suhtlus, ergonoomika ja kasutatavus

In 2000-s only functionality of product was important. But today design is no less important aspect of any IT product. Today's rule of good design is "A product should be so easy to learn that even children can use it without problems". Therefore, we can say that a product is good if it is intuitive and easy to use, and the design does not obstacles its use. Today, by these criteria, I will evaluate two different sites.

Positive exmaple - YouTube



The design of YouTube is very "wide", it occupies the entire screen of a computer (or any other device), which is a significant plus, since every centimeter of the page tries to provide maximum information. although the text is small and poorly readable on the sidebar, the icons responsible for the functionality carry all the necessary information. A huge plus is that neither the logo nor third-party features take up unnecessary visual space. The interface is small enough not to distract the user, but large enough to be easily recognized. The number of icons depends on the screen size, which makes it comfortable to use YouTube for people with both large and small screens. It is also worth mentioning that YouTube almost does not use any colors, we can say that the interface of YouTube (besides video) is almost monochrome. This is also a huge plus as it doesn't distract the user.

Negative example - Postimees.ee


As a negative example, I want to mention postimees.ee. When you enter the page, you see only about 1/3 of the information. The upper part is closed by an oversized logo and a quote (which could just as well be in the news feed), which occupy almost a quarter of the screen. on the other hand, a third of the screen is occupied by a request to purchase a newsletter subscription. I understand that Postimees is commercial company. But by causing negative emotions during the first experience with the "product", they clearly reduce the likelihood of selling their service. It is also worth mentioning that while blue and yellow work well in contrast in general design, the "yellow square" is a great distraction from watching the news. I would also like to say that the interface is not so convenient, due to too small icons with news. Due to pretty "narrow" page design, it would be possible to significantly increase the speed of obtaining information by reducing the number of news in a row from 4 to 3 and even taking into account that the material of news articles is interesting and of high quality, an unsuccessful interface can cause rejection among some of the potential audience.

 Kenshi: the cowboy coding. Kenshi is a survival-sandbox-RPG game in a post-apocalyptic,  "sword-punk"  setting. This game has a large community due to its well-developed world, interesting mechanics, and also because of charismatic characters like "Beep".  First five-six years it was developed by one person. To get by , he had to work minimum wage security guard job in the nights. However, then, when the game gained its first fans, the development group grew significantly. The developers do not have a specific plan of action, they are just trying to bring the game to the state of " the dream game ". For this reason, we can say that due to the lack of almost any plans, Kenshi is an example of cowboy coding. Youtube - Advertising model + freemium  YouTube is one example of a collection of several business models. This company uses the "carrot and stick" trick. Before the video, the user must watch one (or several, damn you YouTube) commercials. Fo

8.IT proffesional... ?

 Estonia is a small country with a well-developed IT industry, which means that competition in this area is also very tough. Nowadays, you will not surprise anyone with a higher education and knowledge of Python (or JavaScript), so programmers, in order to be able to break into high positions, often try to know the widest possible range of languages. Now you can often see a programmer who knows at least 3-4 languages ​​besides Python well. The the requirements  all over the world    for programmers are the same everywhere, but due to the fact that Estonia is a relatively small country, programmers are in constant competition. On the one hand, this limits the total number of "workforce", but it also means that the skills and competence of programmers in Estonia can be significantly higher than in other countries, where the population can be significantly larger. The most important skills for a programmer right now is adaptability. The ability to work in pairs / small groups /

1.  Cicret Bracelet   In 2014, Cicret announced a device that used a projector to display an image on the inside of the arm. This invention seemed so innovative that it swept the Internet with a huge noise. Many news sites were releasing news that Cicret would “turn your hand into a full-fledged tablet.” After all this hype, it was no surprise that Cicret raised massive amounts of money through its crowdfunding company  Go Fund Me. After the initial excitement passed, people starts to asking questions. How does this bracelet work? When will it go on sale? Is it even possible to make such gadget? Cicret was silent for a long time, until the famous debunker Captain Disillusion released a video on his channel about the fact that at the moment it is impossible to make a Cicret Bracelet.   After the revealing video came out, Cicret released a video with a prototype that obviously wasn't look like what they had originally promised, which caused massive discontent among people. In 2017
