From the Data is Beautiful subreddit, a visualization of how long it takes for light to travel from Earth to the Moon, and then from Earth to Mars.
Enjoy Markus Stark's zoomy video of the moon, shot with a Leica 400mm F2.8 lens (about $10k, used) attached to a Panasonic GH4 with 1.4x, 2x, and 2x Leica APO focus module extenders. [via Leica Rumors] The video clips were filmed in August 2015 at only 290m above sea level (camping side in Germany). Some zooming… READ THE REST
On Sunday, Ingenuity—the small helicopter delivered to the surface of Mars by the Perseverance rover—will, hopefully, take its first flight. The distance between Earth and Mars means that lagtime precludes real-time remote control. The helicopter flies autonomously, but the helicopter's digital twin had a lot of practice in simulations back on Earth. At IEEE Spectrum,… READ THE REST

They aren't really built for those heavy-duty power tasks that you might encounter. You know…like when your car battery is… READ THE REST
If you're in the market for a laptop, it's tough out there. Between companies producing incredibly similar models with only slight tweaks and variations and shoppers starved for reliable sources of information to make sense of it all, you practically have to be a computer science major to untangle what's what. And when shoppers get confused… READ THE REST
If you've ever seen a 3D printer in action, you know it's a pretty wondrous process. Even if you're crafting nothing more than a plastic bauble or a geometric shape, just watching that filament settle and build into something recognizable and useful is fairly awe-inspiring. And man, to a kid…it's like a miracle. And they really,… READ THE REST
