Rotor sails rely on a bit of aerodynamics known as the Magnus effect. In the 1850s, German physicist Heinrich Gustav Magnus noticed that when moving through air a spinning object such as a ball experiences a sideways force. The force comes about as follows. If the ball were not spinning, air would stream straight past it, creating a swirling wake that would stretch out directly behind the ball like the tail of a comet. The turning surface of a spinning ball, however, drags some air with it. The rotation deflects the wake so that it comes off the ball at an angle, closer to the side of the ball that's rotating into the oncoming air. Thanks to Isaac Newton's third law that every action must have an equal and opposite reaction, the deflected wake pushes the ball in the opposite direction, toward the side of the ball that's turning away from the oncoming air. Thus, the spinning ball gets a sideways shove.
"The matter has been concluded," was Upload's official statement. Neither Scott, nor her legal counsel, responded to a request for comment for this story.

We also are focused on consumer protection and have developed a comprehensive portfolio of services to support all U.S. consumers, regardless of whether they were impacted by this incident." Equifax is now alerting customers whose information was included in the breach via mail, and is working with state and federal authorities.
UPDATE (9/7/17): According to Bloomberg, "three Equifax senior executives sold shares worth almost $1.8 million" in the days after the company discovered the security breach. Regulatory filings show that three days after the breach was discovered on July 29th, Chief Financial Officer John Gamble sold shares worth $946,374 and Joseph Loughran, president of U.S. information solutions, exercised options to dispose of stock worth $584,099." Meanwhile, "Rodolfo Ploder, president of workforce solutions, sold $250,458 of stock on Aug. 2."
Let's list the most famous ones:
- DownThemAll is still largely irreplaceable since you can download from many parts of the internet much faster if you split the downloaded files in chunks and download them simultaneously;
- NoScript: allows you to whitelist JS execution only for websites that you really trust; JS has been used as an attack and tracking tool since its inception;
- Status-4-Ever and Classic Theme Restorer return Firefox to the time when it was a powerful tool with its own identity and looks, and not a Chrome clone;
- UnMHT add-on allows you to save complete web pages as a single MHT file;
So what will you do less than a year from now?
