Rupert's Property

You can cut a hole in a cube that’s big enough to slide an identical cube through that hole! Think about that for a minute—it’s kind of weird. Amazingly, nobody could prove any convex polyhedron doesn’t have this property! It’s called ‘Rupert’s property’. Until this week. This week Steininger and Yurkevich proved there is a convex polyhedron that you can’t cut a hole in big enough to slide the entire polyhedron through the hole. It has 90 vertices, and apparently 240 edges and 152 faces. To

RSS is awesome

Don’t Worry, ‘Wednesday’ Fans, the Coma Is Almost Over

The Wednesday hype might seemingly be waning, but it’s worth noting that perhaps the Tim Burton series could just be experiencing a lull thanks to its strange release schedule. With season two part one’s debut going from the top of the streamer’s charts to dropping 50%, according to What’s on Netflix, this might just be a sign that fans are eagerly awaiting to binge the season in full. One of our criticisms of the staggered summer and fall releases was that despite this season being the best ye

780,000 Ryobi Pressure Washers Recalled Due to Explosion Risk

Owning a pressure washer can seem like a boon for homeowners wanting to clean decks, driveways and other outdoor surfaces. But if you own one, check the brand and model immediately: around 780,000 Ryobi-branded pressure washers sold at Home Depot and other US and Canadian retailers are being recalled. The hazard is serious, according to a notice posted Thursday by the Consumer Product Safety Commission. "The pressure washer's capacitor can overheat and burst, causing parts to be forcefully ejec

US targets North Korean IT worker army with new sanctions

The U.S. Treasury’s Office of Foreign Assets Control (OFAC) has sanctioned two individuals and two companies associated with North Korean IT worker schemes that operate at the expense of American organizations. These schemes involve placing in U.S. firms skilled tech workers with stolen or fabricated identities and using so-called “laptop farms” to hide the true location of the employees.

Uncertain<T>

You know what’s wrong with people? They’re too sure of themselves. Better to be wrong and own it than be right with caveats. Hard to build a personal brand out of nuance these days. People are attracted to confidence — however misplaced. But can you blame them? (People, that is) Working in software, the most annoying part of reaching Senior level is having to say “it depends” all the time. Much more fun getting to say “let’s ship it and iterate” as Staff or “that won’t scale” as a Principal.

‘Tron: Ares’ Uses Elements From a Decade-Old Script

When Tron: Ares hits theaters in October, it’ll be the end of a 15-year roller coaster ride. The second Tron, Tron: Legacy, was released in December 2010, and almost immediately, talks began about a sequel. In that time, multiple writers (15, in fact), directors, and actors attempted to return to the Grid only to fall short. But now, it’s coming, and it’s very different from what fans expected 15 years ago, though some key elements remain. One of the first writers brought on to pen Tron 3 was D

New research published Thursday, August 28, in the journal Science, offers new insight into the genetic shifts that helped t
