Productivity trainer Kosio Angelov built a paid course at Udemy on how to beat procrastination, and over a thousand people took it. Now Angelov has ditched the $47 price tag and released the course on YouTube for free.

If you’re looking for a much affordable alternative to Photoshop for Windows, you may want to check out this indie-made image editor. Affinity Photo, the same program that won Mac App of the Year in 2015, is now officially available for Microsoft’s OS. Its developers released a beta version for the platform in November, but the full version (with all the features Mac users enjoy) is now available for $40 until December 22nd — $50 after that. The app’s developers have also released a huge update for Mac with a bunch of new features that will also come with the newer Windows app, including the ability to edit 360-degree images.
In addition to "an all-new way to edit 360-degree images," Affinity Photo version 1.5 offers all these:
The free update also adds support for the Touch Bar, the secondary OLED screen that takes the function keys’ place on the latest MacBook Pro. To read more about version 1.5 and to buy the app for either or both platforms, make sure to head over to the app’s website.

A group of engineers have developed a new jet engine tech that can improve planes’ fuel efficiency by four to eight percent, and NASA has begun testing it out. They created a new type of engine propulsor — composed of the fan and a part called the inlet, which directs air into the engine — designed to be embedded into a jet plane’s body. Jet engines are typically placed away from the aircraft’s surface, because of a highly distorted film of air called the boundary layer that envelopes the plane as it zooms through the sky. This new type of jet engine propulsor takes advantage of the boundary layer instead.
As NASA Glenn engineer David Arend explained:
"Studies backed by more detailed analyses have shown that boundary layer ingesting propulsors have the potential to significantly improve aircraft fuel efficiency. If this new design and its enabling technologies can be made to work, the boundary layer ingesting (BLI) propulsor will produce the required thrust with less propulsive power input. Additional aircraft drag and weight reduction benefits have also been identified."
Since the boundary layer’s distorted flow can wreck fans, the team from United Technologies Research Center and Virginia Polytechnic and State University had to create much stronger ones. Over at NASA’s Glenn Research Center in Cleveland, the engineers also had to spend years modifying the facility’s wind tunnel to be able to fit the system. This is the first propulsor designed to ingest the boundary layer to ever be tested, so Glenn Center’s engineers have to put it through a battery of tests to make sure it works. They’ll be testing it under different wind speeds and varying boundary layer thickness to see how those factors affect the "propulsor’s performance, operability and structure."

If you haven’t canceled your subscription already and are still enjoying DIRECTV NOW, you will be happy to learn that a new feature has been implemented into the service this morning.
From what DIRECTV details, users can now use the ability to rewind TV up to 72 hours, meaning you don’t need to worry about missing your precious shows.Â
For example, if that new episode of Family Guy airs at 9PM, but you won’t be home until 11:30PM, you can simply rewind the channel and get to your show. Do note, DIRECTV mentions that only select networks offer the feature, but the big ones are all supported – FOX, TBS, MTV, TNT, NBC, etc.
The feature is live for all subscribers, so go enjoy it.
