The nuclear fusion breakthrough – false hope or tantali…

It is a thought as old as human existence. It is as old as the first time a sentient being looked up at the sky and realised the great glowing thing in the sky above was what gave the Earth its warmth and light throughout the day. How could they capture some of it? And, could they find something like it right here on Earth for themselves?  Speculations such as those have triggered humanity’s myths and legends — as well as its scientific explorations. In one of his most lyrical short stories, The Golden Apples of the Sun, Ray Bradbury, the renowned 20th-century speculative fiction author, described a rocket expedition from Earth whose mission was to skim right across the surface of the sun to scoop up a cargo of the sun’s actual material — the very hydrogen being fused into… Source link

CVE Number Description Base Score Reference CVE-2019-5924 Cross-site request forgery (CSRF) vulnerability in Smart Forms 2.6.15 and earlier allows remote attackers to hijack the authentication of administrators via a specially crafted page. 8.8 https://nvd.nist.gov/vuln/detail/CVE-2019-5924 CVE-2019-6727 This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the XFA remerge method. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of… Source link

Researchers Detail Critical RCE Flaw Reported in Popular vm2 JavaScript Sandbox

Researchers Detail Critical RCE Flaw Reported in Popular vm2 JavaScript Sandbox

A now-patched security flaw in the vm2 JavaScript sandbox module could be abused by a remote adversary to break out of security barriers and perform arbitrary operations on the underlying machine. “A threat actor can bypass the sandbox protections to gain remote code execution rights on the host running the sandbox,” GitHub said in an advisory published on September 28, 2022. The issue, tracked as CVE-2022-36067 and codenamed Sandbreak, carries a maximum severity rating of 10 on the CVSS vulnerability scoring system. It has been addressed in version 3.9.11 released on August 28, 2022. vm2 is a popular Node library that’s used to run untrusted code with allowlisted built-in modules. It’s also one of the most widely downloaded software, accounting for nearly 3.5 million downloads per… Source link

Sexy/Unsexy, Practical/Impractical: There Are Mutts & Magnificent Beasts In Energy

What’s a day without a provocative quadrant chart that makes many people howl with outrage (or at least mutter at their screen)? Well, not this day. Over on LinkedIn, Peter Clarkson of Woodside Energy in Australia triggered me with the idea of a way to categorize various decarbonization solutions, a standard quadrant chart with sexy/unsexy and practical/impractical as the options. He okayed me stealing the idea, saying that as he hadn’t actually done anything with the idea at all, he couldn’t claim it as intellectual capital. Thank you, Peter. For those interested in other areas I’ve spent time on, such as ground transportation, aviation, and marine shipping, you’ll be either pleased or displeased to know that I have charts on those subjects already in hand and two more in… Source link

Supersonic Jet Hyper Sting would fly from NYC to London in just 80 minutes

A newly designed supersonic jet would be able to fly passengers from New York City to London in just 80 minutes. Dubbed the Hyper Sting, the conceptual plane would be nearly twice as large and travel twice as fast as the world’s last commercial supersonic jet, Concorde, which was retired in 2003. The Hyper Sting, at 328 feet long with a 168-foot wingspan, would dart up to 170 passengers across the Atlantic and beyond at speeds of 2,486mph — more than three times the speed of sound. “Concorde was a brilliant piece of machinery, a noble experiment, but it put too many emissions in the environment, too much noise into our communities, and was too expensive to operate,” the Spanish designer of the craft, Oscar Viñals, told The U.S. Sun. Two… Source link
