Submission + - Intel Unveils 'Breakthrough' 49 Qubit Quantum Computer (extremetech.com) 1

cold fjord writes: Extremetech reports, "At CES 2018 this week, Intel’s CEO . . .declared the company’s new 49-qubit quantum computer represented a step towards “quantum supremacy.” A 49 qubit system is a major advance for Intel, which just demonstrated a 17-qubit system two months ago. Intel’s working with the Netherlands-based Qutech on this project, and expanding the number of qubits is key to creating quantum computers that can deliver real-world results. . . . “Qubits are tremendously fragile: Any noise or unintended observation of them can cause data loss. This fragility requires them to operate at about 20 millikelvin – 250 times colder than deep space.” This is also why we won’t be seeing quantum computers in anyone’s house at any point."

Submission + - Researchers now able to reconstruct past ocean temperatures (ucsd.edu)

RoccamOccam writes: There is a new way to measure the average temperature of the ocean thanks to researchers at Scripps Institution of Oceanography at the University of California San Diego. In an article published in the latest issue of the journal Nature, geoscientist Jeff Severinghaus and colleagues at Scripps Oceanography and institutions in Switzerland and Japan detailed their ground-breaking approach.

“This method is a radically new way to measure change in total ocean heat,” said Severinghaus. “It takes advantage of the fact that the atmosphere is well-mixed, so a single measurement anywhere in the world can give you the answer.”

In the study, the scientists measured values of the noble gases argon, krypton, and xenon in air bubbles captured inside ice in Antarctica. As the oceans warm, krypton and xenon are released into the atmosphere in known quantities. The ratio of these gases in the atmosphere therefore allows for the calculation of average global ocean temperature.

“Our precision is about 0.2 C (0.4 F) now, and the warming of the past 50 years is only about 0.1 C,” Severinghaus said, adding that advanced equipment can provide more precise measurements, allowing scientists to use this technique to track the current warming trend in the world’s oceans.

Already it's being exploited and wasting everyone's computing power to scrape up cryptopennies

By default uBlock Origin includes a block list to protect against resource abusing scripts, such as coin mining scripts. And, if you think the default block list is not enough, you can add additional block lists to uBlock Origin like the NoCoin list. So protect yourself with uBlock Origin and browse happy.

Firefox relies on gstreamer for H.264 support on Linux. You mustn't have H.264 support installed in gstreamer (or you have an old Firefox build without gstreamer support), such is the hassle of patent royalty-bearing codecs. VP9 has made good progress and hopefully AV1 will finally cement royalty-free video formats as the standard on the web.
