Cray versus Raspberry Pi

news.ycombinator.com Unknown 2026-03-15 21:58:29

Please visit the sponsor! Cray versus Raspberry Pi I fondly recall the era when the pinnacle of supercomputing was the Cray 1. Even the shape of this computer was massively different to anything that came before and it was so futuristic that it could have come straight from a scifi movie. While almost all other computers of the 1970s were just a collection of huge rectangular cabinets with blinky lights and perhaps a few tape drives, the Cray 1 looked more like a piece of space-age furnitu

A shortage of high-voltage power cables could stall the clean energy transition

techspot.com Skye Jacobs 2026-03-19 14:27:00

In a nutshell: As nations set ever more ambitious targets for renewable energy and electrification, the humble high-voltage cable has emerged as a linchpin – and a potential chokepoint – in the race to decarbonize the global economy. A Bloomberg interview with Claes Westerlind, CEO of NKT, a leading cable manufacturer based in Denmark, explains why. A global surge in demand for high-voltage electricity cables is threatening to stall the clean energy revolution, as the world's ability to build n

Scientists Reveal Easy Three-Step Plan to Terraform Mars

futurism.com Unknown 2026-03-19 14:45:29

Terraforming, the act of radically transforming a planet's climate and environment to make it suitable for human habitation, currently belongs to the realm of science-fiction. But it's possible, at least in theory, and the idea of terraforming our nearest candidate planet for off-world colonization, Mars, has captivated us for generations. But how would we even begin to pull off such a monumental feat of engineering? You can basically boil it down to three simple steps, argue the authors of a r

You’ll Guffaw When You Hear How Much Self-Driving Waymos Cost Compared to Human-Driven Ubers

futurism.com Unknown 2026-03-19 14:30:32

The whole point of self-driving taxis is, in theory, to save costs on human labor — but Waymo, Google's glitchy robotaxi service, doesn't appear to be any cheaper at all, at least for now. In a report shared with TechCrunch, the ride-hailing data aggregator Obi found that riding with Waymo is pretty much always more expensive than taking a ride with a human-driven Uber or Lyft. For its analysis, Obi analyzed roughly 90,000 records from Uber, Lyft, and Waymo rides between March 25 and April 25

Using `make` to compile C programs

I have never been a C programmer but every so often I need to compile a C/C++ program from source. This has been kind of a struggle for me: for a long time, my approach was basically “install the dependencies, run make , if it doesn’t work, either try to find a binary someone has compiled or give up”. “Hope someone else has compiled it” worked pretty well when I was running Linux but since I’ve been using a Mac for the last couple of years I’ve been running into more situations where I have to

Testing kamado grills is an intense experience for a griller. It requires playing with fire (literally) and high temperatures, although in a controlled, responsible way. The most critical element to kamado's performance is heat, specifically temperature control and how well a grill holds to one temperature. To smoke meat low and slow, that magic number is 225℉. Good smokers, kamados or otherwise, will stick to this temp for as long as 12, 15 or 20 hours. This means the temperature gauge is key a
