Pavel Prikhodko, Ph.D. Machine Learning

In the United States, lotteries are run by 47 jurisdictions, including 44 states plus the District of Columbia, the U.S. Virgin Islands and Puerto Rico. The most recent U.S. lottery to be legalized was in Wyoming, where it began operation in July 2013.

There are two major lottery games: Mega Millions and Powerball. These companies are offered in nearly all jurisdictions that operate lotteries. Among the states that do not have lotteries are Mississippi, Utah and Alabama (because of religious objections). In the modern technology era, plenty of new apps have been created for people to purchase lottery tickets on their gadgets (such as smartphones or laptops).

But what is the current state of affairs? Has the electric vehicle market really taken off outside of California? And most importantly, is the existing infrastructure ready for mass-market EV cars?

What is cloud computing and why is it important?  In recent years there has been a surge in the number of internet-based services that provide shared computer resources, minimizing both upfront and continuing maintenance costs for new projects. It is often regarded as most useful for smaller setups, as it allows access to a significant amount of resources regardless of the project size.

Despite technically existing since the 1990s, the technology only really took off in 2009 (Microsoft announced its Azure service in October 2008). After this, it didn’t take long for major U.S. companies to start patenting their developments.

The “cloud” term started gaining popularity in new U.S. patents in 2010. We can already say that it was not a one-time fad — each year since then, the total number of patents including the term has increased.
