Drones Rearrange This Canopy Prototype So You're Always in the Shade

When they're not rebuilding the environment or exploring Mars, the drones of the future may help us avoid some of life's minor inconveniences. A group of masters students at the University of Stuttgart envisioned a fleet of drones that does just that for their thesis project: As New Atlas reports, the drones are part of a roaming canopy, responding to sunlight above and movement below to ensure you're always in the shade.

Without the drones, the prototype, dubbed Cyber Physical Macro Material, resembles a normal stationary structure. Tall black poles support panels that fit together magnetically, protecting whoever's beneath them from the sun's rays. But this design is only effective when the sun is in a certain part of the sky: As the day progresses, the canopy's shadow shifts, and people are forced to move with it if they want to stay out of the light.

But these panels don't stay in the same spot for long. They come equipped with special sensors that keep track of the orientation of the sun and a communications system that corresponds with autonomous drones nearby. If a panel is no longer keeping the ground beneath it shady, a drone will glide over, lift it up, and snap it into a different part of the canopy like a puzzle piece. Drones can also rearrange the panels in response to the size and location of the crowd beneath them, which means the same structure that shades a few pedestrians can also keep a larger party cool.

There are legal and logistical hurdles the project would need to overcome before becoming a system in a real-world, but the researchers behind it say that for now it's meant to get people thinking about the potential applications for drones. A press release from the university reads, "With its ability to continuously reconstruct during use, the system challenges pre-conceived ideas of robotic digital fabrication and sophisticated pre-fabrication for architecture."

Twitter Bug Accidentally Alerted Users When Someone Unfollowed Them

Social media networks may notify you every time your former high school classmate has a birthday, but there's one piece of information most sites choose not to share with users. When someone unfriends or unfollows you, platforms like Facebook and Instagram will save you the pain of knowing about it. This is normally the standard on Twitter, but thanks to a new bug, some Twitter users have received notifications when people unfollowed them, Vice reports.

For several days in June, many Twitter users reported receiving push notifications on their phones every time one their followers removed them from their feed. The notifications didn't clearly reference the awkward situation: The bug told users that someone had “followed them back” when they had actually hit the unfollow button. People eventually caught on to what was really happening.

The bug apparently didn't affect all users, so if you unfollowed someone on Twitter in the past week or so, there's a chance they didn't notice. Though if they really wanted to know, there are third-party apps that show Twitter users who unfollowed them.

According to Fast Company, Twitter has resolved the issue and users no longer risk getting their feelings hurt every time they check their notifications. So feel free to continuing curating the list of people you follow in privacy.

This Amazingly Simple Google Docs Hack Is a Game-Changer

The seconds it takes to manually open a Google Doc, Sheet, or Slide on your computer are short compared to the time you spend working in them. But if you're already feeling stressed or tempted to procrastinate, the process of going to Google Drive, selecting New, and opening a blank document can be annoying enough to disrupt your workflow. For people looking to maximize as much of their time as possible, Google introduced a hack late last year that creates a new Doc, Sheet, or Slide in seconds.

According to TechCrunch, you can launch a blank Google Doc in less time than it takes to type out a full web address. If you're already signed into your Google account, simply go to your web browser, type in doc.new (no www. required) and hit Enter to go to your fresh, new document. For Google Slides, do the same for slide.new, and for Sheets, use sheet.new. It doesn't matter if you pluralize the name of the app: Typing doc.new or docs.new will bring you to the same place.

Google owns the .new web domain, which allowed it to create these convenient hacks for its users. If you're a frequent user of Google's applications, you can bookmark the addresses so they pop up in your browser suggestions with just a couple keystrokes.

The new document shortcut is pretty straightforward, but there are several more Google Docs features that make life more convenient for users in unexpected ways, including features for automatically transcribing audio and outlining documents.
