    Cryptocurrency faces a quantum computing problem


    There are a whole bunch of air fryers on sale at Best Buy today but this is my pick. The 4-quart size is perfect for most people — not too large and not too small — and the digital interface is handy for quickly firing up wings or fries using the preset programs and not having to hawk it the whole time.

    The real quantum test for cryptocurrencies will be governance structures, not technologies, says Hunter Jensen, chief technology officer of, a company using cryptocurrency for a targeted advertising system.

    Jo Bates-Keegan, Chair of the Badger Trust, said: ‘This is a distressing example of the reality of what badgers face in terms of the development impact on their natural environment – whether it be a huge infrastructure project such as HS2, or one of the many local building projects that take place up and down the country.

    Best Buy’s big sales event is already in full swing, and the big-box retailer has been slashing prices on TVs, headphones, air fryers and more, with the deals rotating on a regular basis. Unlike some of its competitors, Best Buy doesn’t have a clear-cut start and end date for its Black Friday sales, so it’s a good idea to get started now before some of the savings are gone.   

    The Hyperledger Foundation, an open-source software project geared for business uses of blockchain, has begun working on post-quantum cryptography through its Ursa effort, says Daniela Barbosa, Hyperledger’s executive director. Ursa is a library of cryptography software Hyperledger projects can use.

    A Liberian-owned ship called the Beijing is believed to be responsible for the massive oil spill that tarnished Southern California beaches last month after the vessel’s anchor dragged across the seabed and cracked a crucial pipeline

    The Sony WH-XB910Ns are a great, budget friendly option for noise-cancelling headphones. They can also pair to two bluetooth devices at the same time for almost effortless switching between devices. They were even featured in .

    It’s not known why the leak occurred eight months later rather than at the time of the anchor collision. Authorities also are looking into whether other anchors hit and weakened the pipeline or if a preexisting condition with the line was to blame.

    The Surface Laptop Go is a great combination of power and affordability, and this deal makes it even more affordable. Prices start at just $550 for the model with 8GB of RAM and 128GB of storage. If you need to upgrade, you can double the solid-state drive for just $140 more. Both come with a 12.4-inch touchscreen, Intel’s 10th-gen Core i5 and more.

    A problem with the post-quantum cryptography algorithms under consideration so far, though, is that they generally need longer numeric encryption keys and longer processing times, says Peter Chapman, CEO of quantum computer maker IonQ. That could substantially increase the amount of computing horsepower needed to house blockchains.

    Ultimately, though, cryptocurrency’s organic, self-directed development suggests people will update the digital asset technology to surmount quantum computing’s challenges, Situs Judi Slot Terbaik di Dunia says David Sacco, who teaches at the University of New Haven.

    The leak stemmed from a 17.5-mile pipeline spanning from Amplify’s Elly oil rig seven miles off the coast of Long Beach to a pump station operated by Beta Offshore, a Long Beach unit of Houston-based Amplify, and spread to a slew of beaches and coastal areas across California’s Orange County


    iRobot’s Braava mop will keep you from crying over spilled milk. Like the robotic vacuum from iRobot, this mop automatically maps out cleaning for your rooms and navigates easily around objects and furniture. The jet spray works on all finished hard floors including hardwood, tile and stone. In addition to scheduled cleanings, it also targets specific spills via voice command or the iRobot Home app.


    With 5 cubic feet, this set is designed to let you wash king-size sheets and comforters at home. The set features AI technology to detect which settings to use on your load, and a preloaded dispenser holds up to 18 loads with one fill, so you can have your machine ready to go. It’s fast, too, cleaning loads in under 30 minutes.

    Such governance could reward cryptocurrencies that have stronger central powers, such as Dash with its masternodes or even “govcoins” issued by central banks, that can in principle move more swiftly to adopt post-quantum protection. But it presents a conundrum in the crypto community, which often rejects the idea of authority.
