Quantum Computer Made from Photons Achieves a New Record

Boson sampling can be thought of as a quantum version of a classical device called the bean machine. In that device, balls are dropped onto rows of pegs, which they bounce off of, landing in slots at the bottom. The random motion of the balls typically leads to a normal distribution in the slots: most balls fall near the center, and fewer fall toward the sides, tapering off at the edges. Classical computers can easily simulate random motion to predict this result.

Salesforce Transit Center: San Francisco’s $2.2 Billion Cracks

And the review determined that the two affected beams, both over 60 feet long, barely moved an inch due to the fractures. The redundancies in design guaranteed the beams’ stability. The overall safety of the building was never compromised. If those workers hadn’t discovered the cracks by chance, we still might not know about them.

US Court Shields Internet Subscribers From Futile Piracy Complaints

All in all the Court sees no other option than to deny the request for expedited discovery. This is good news for the people who were targeted by these lawsuits, as they won’t be identified. At the same time, it means that Strike 3 can’t continue these cases, as it can’t name a defendant.

How DARPA Trucked Its Massive Radio Frequency Testbed Across The United States

Colosseum may look like a data center, but in reality, it’s a massive radio-frequency emulation testbed that DARPA built for its Spectrum Collaboration Challenge (SC2). SC2 has been a three-year competition to demonstrate the validity of using artificial intelligences to work together in order to use wireless spectrum more efficiently than operating on pre-allocated bands would be.

YouTube gets alleged copyright troll to agree to stop trolling YouTubers

YouTube first sued Brady in August after learning that he targeted a couple of Minecraft and gaming creators — “Kenzo” and “ObbyRaidz” — by using false copyright claim takedowns. The company removed the videos, as the company is required to do when a claim is submitted. YouTube only pursued legal action after it was informed that Brady was allegedly using copyright strikes as a way to pressure creators into paying a lump sum of cash. Brady would allegedly strike two videos on a channel and then demand cash; three strikes on a channel result in it being terminated.

According to a slashdot comment this could be criminal.

Sudo Flaw Lets Linux Users Run Commands As Root Even When They’re Restricted

What’s more interesting is that this flaw can be exploited by an attacker to run commands as root just by specifying the user ID “-1” or “4294967295.”

That’s because the function which converts user id into its username incorrectly treats -1, or its unsigned equivalent 4294967295, as 0, which is always the user ID of root user..

Fortnite has been down for hours as millions of players stare at a black hole

One of the biggest games in the world has been unplayable since this afternoon. Ahead of its next season — or possible a completely new chapter — Fortnite has gone down in just about every way imaginable. It’s widely believed that when the game is back up and running it will be a rebooted version featuring a brand new map.

Why big ISPs aren’t happy about Google’s plans for encrypted DNS

Widespread adoption of DoH would limit ISPs’ ability to both monitor and modify customer queries. It wouldn’t necessarily eliminate this ability, since ISPs could still use these techniques for customers who use the ISP’s own DNS servers. But if customers switched to third-party DNS servers—either from Google or one of its various competitors—then ISPs would no longer have an easy way to tell which sites customers were accessing.

Cheating allegations against poker player Mike Postle halt livestreamed games

The RFID cards contain chips, that combined with readers in the poker table, transmit information about each player’s hole cards, so that viewers can see the cards on the broadcast (which is on a 30-minute delay to protect game integrity).
