The “most advanced piece of malware” that China-linked hackers have ever been known to use was revealed today. Dubbed Daxin, the stealthy back door was used in espionage operations against governments around the world for a decade before it was caught.
But the newly discovered malware is no one-off. It’s yet another sign that a decade-long quest to become a cyber superpower is paying off for China. While Beijing’s hackers were once known for simple smash-and-grab operations, the country is now among the best in the world thanks to a strategy of tightened control, big spending, and an infrastructure for feeding hacking tools to the government that is unlike anything else in the world.
Rice University lab manipulates ultracold Rydberg atoms to mimic quantum interactions.
Our spatial sense doesn’t extend beyond the familiar three dimensions, but that doesn’t stop scientists from playing with whatever lies beyond.
Rice University physicists are pushing spatial boundaries in new experiments. They’ve learned to control electrons in gigantic Rydberg atoms with such precision they can create “synthetic dimensions,” important tools for quantum simulations.
Tesla is reportedly finally going to receive final approval to start production at Gigafactory Berlin this week after months of delays.
Gigafactory Berlin, a critical new factory for Tesla’s plans to expand in Europe and improve its manufacturing and distribution efficiency, has been in limbo for months.
The automaker has yet to secure the needed environmental permit to start producing vehicles for customer deliveries.
“Aside from vastly expanding the geographic coverage of this energy source, the sheer feat of engineering involved deserves a mention. Until now, the deepest artificial point on Earth has been the Kola Superdeep Borehole in Russia. That Soviet-era project reached 12,262 metres (40,230 ft) below ground. Quaise would smash that record if achieving the full potential of 20,000 metres (65,600 ft).” https://www.futuretimeline.net/blog/2022/02/28-geothermal-en…nology.htm
A new drilling technology able to reach depths of 20 km could enable geothermal power to be accessed almost anywhere in the world.
We all know Linux is written in C. What you may not know is that it’s written in a long-outdated C dialect: The 1989 version of the C language standard, C89. This is also known as ANSI X3.159‑1989, or ANSI C. Linus Torvalds has decided that enough is enough and will move Linux’s official C to 2011’s C11 standard.
The Linux kernel’s foundation is the ancient C89 standard of C. Now, Torvalds has decided to upgrade to 2011’s more modern C11 standard.
Interfacing technology and electronics with the real world is often fairly tricky. Complexity and edge cases work their way in to every corner of a project like this; just ask anyone who has ever tried to operate a rover on Mars, make a hydroponics garden, or build almost any robotics project. Even those of us who simply own a consumer-grade printer are flummoxed by the ways in which they can fail when manipulating single sheets of paper. This robotic lawnmower is no exception, driving its creator [TK] to extremes to get it to mow his lawn.
[TK] actually had a platform for his autonomous mower ready to go thanks to a previous build using this solar-powered robot to explore the Australian outback. Adding another motor to handle the grass trimming seemed simple at first and he set about wiring it all up and interfacing it to the robot. After the first iteration he found the robot was moving too fast to effectively cut the grass, so he added a more powerful cutting motor and a gearbox to help the mower crawl more slowly over the lawn. Disaster struck when his 3D printed mount for the steel cutting blades shattered, but with [TK] uninjured he pushed on with more improvements.
As it stands right now, the mower can effectively cut the grass moving forward even with the plastic-only cutting blades that [TK] is using now for safety reasons. The mower stripped its reverse gear so there still are some improvements to make before this robot is autonomously cutting the lawn without supervision. Normally we see lawnmowers retrofitted with robotics rather than robotics retrofitted with a lawnmower, but we’re excited to see any approach that lets us worry about one less household chore.
