In terms of technology, many things can happen in a week. The constant impact of news makes it impossible for only mortals in real life to follow everything. That\'s why we put together a quick and dirty list of this week\'s \"stop tech story\", from surprising solar roof prices to vending machines selling clothes --it’s all here. Anyone who has to change the roof can prove that this is a small fee. Homeowners may have a better solution, according to Bloomberg, not only with lower upfront costs, but also with savings over time. In 2016, Tesla bought SolarCity, and about 85% of shareholders voted to pass the deal, making SolarCity the undisputed king of the Sun --to-vehicle energy. Shortly after the deal was finalized, Tesla CEO Elon Musk announced that the company\'s new solar roof is less expensive to make and install than traditional roof materials. All these savings, he claims, will be ahead of your electricity bill savings. Musk said, \"Electricity is just a reward. Read: As a result, Tesla\'s solar roof is cheaper than the ordinary roof. What is smart city? People who even built them don\'t seem to know yet. Bob Bennett, Missouri\'s chief innovation officer, told Digital Trends: \"Let 10 people ask in one room what a smart city is and you get 11 answers . \". This may be true, but most people involved in smart city projects agree on one thing: no one is really there yet. \"I think this is the Wild West, and the smart city has a different meaning for everyone,\" said Jarett Wendt, executive vice president of strategic innovation at Panasonic . \". When asked about examples of smart cities ( This is Our four favorite. Instead, Bennett gives an example of a smart silo Some cities are particularly prosperous, although they may not form a larger pattern. Washington D. C. Good water analysis. Seattle did a great job in environmental protection. There are thousands of smart street lights in San Diego. In South Korea, Matsushima, as a smart city, has benefited from the beginning. Many of its lessons, however, do not necessarily apply to cities trying to work with existing infrastructure.

Olders Herley is right to think that speed is the only real modern feeling. He did not mention how interesting it was. That said, these 25 cars are more than just interesting -- They produce the fastest cars in the world. \"Production\" is emphasized here \", \"Race driver and one Custom work is not required. We are also trying to limit the choice to cars that claim to have the highest speed, which are generally considered legal by car Media and sanctions groups. There are also some cars on the horizon that seem ready to remove some names from this list. SSC still hopes to regain the title of the world\'s fastest car with 350-its1 The horsepower Tuatara and Koenigsegg claim that the top speed of their 1:1 is over 273 miles per hour.

Then, in early 1950, an electrical company called west bend began selling an electric bean to facilitate the cooking of peppers and a variety of other foods. Since then, the slow cooker has entered the kitchens around the world; The ability of some supermarkets is not just to cook food slowly. When most people think of slow cooking recipes, they think of simple instructions that allow you to throw ingredients into the pan and walk for 8 hours. This part is true, though. Cooking in a slow cooker is not difficult and convenient Your food may not come out if you do not follow the best practices. If you do not use the slow cooker properly, your meal may become unappetizing, you may have a fire at home, or you may have someone sick.

A new computer science program at Lawrence University of Science and Technology in Michigan uses machine learning and data science to take a similar approach to 6,082 European football players. This is done through a computational model that calculates the highest and lowest paid players in the world based on skills ( The latter group is Billy Bain- Probably the style manager is most interested in it! ). \"It is common to compare personal measurements in sports,\" Lior Shamir, one of the collaborators of the paper The author tells Digital Trends. \"However, the skill mix of football players, so as long as the number of goals is compared, it can reflect the real value of the players in a very part. What we\'re doing here is developing a computational model that combines 55 measurement attributes that reflect the player\'s abilities. When comparing the model with the player\'s salary, we can estimate each player\'s salary based on his performance on the court and his comparison with all the other players.
