On November 12, 2020 — in the midst of a pandemic that has locked many people in their homes, Sony launched their much-anticipated PS5. What can the launch of this gaming console teach us about economics? The ugly side of supply and demand.

Mechanical keyboards look and sound great. Not only that, but they’re a lot more fun to type on as the feedback is more tactile than a normal keyboard. However, mechanical keyboards are expensive, with some of the costliest models ranging from a couple hundred dollars to over a thousand dollars. When investing in a piece of tech like this, are there any benefits to typing speed?
When I first discovered mechanical keyboards, it was back in 2013. I was an undergraduate at UC Berkeley, and just splurged $120 on a new keyboard.
As a consumer, Yelp provides helpful information when you’re looking to visit a business for the first time. Whether it’s looking for a new place to eat Chinese food, a new gym to join, or a place to get your haircut — Yelp is a great resource for making a very personal decision on whether or not you want to visit a business.
Yelp data becomes fascinating when you take a macro view. This requires scraping business data across hundreds of American cities. By doing this, we have one of the richest business datasets that covers a majority of America…

Whether you’re trying to build a portfolio to be a stronger data science candidate, or looking to take on a new data-related challenge that can earn you money — I want to make the case the Daily Fantasy Sports is a great candidate for your next project.
What is Daily Fantasy Sports (DFS), and how is it related to data science? DFS mirrors season-long fantasy sports but condenses it into a shorter, more sweat-inducing format. With a lot of sports being book-shelved this year, eSports has also become a popular category under this model.
