Two undersea communications cables in the Baltic Sea have been knocked offline, and at least one appears to have been physically cut. CNN received confirmation from a local telecom company that a cable between Lithuania and Sweden was cut on Sunday morning. A second cable, about 60 to 65 miles from the first, routes communications between Finland and Germany. The cause of that outage has yet to be determined, but officials suspect intentional damage. The outages follow a September warning from the US about an increased risk of Russian sabotage of undersea cables. That came after a joint investigation from public broadcasters from Sweden, Denmark, Norway and Finland that Russia had deployed a fleet of spy ships in Nordic waters. They were reportedly part of a program designed to sabotage the cables (and wind farms). This doesnt leave the European nations entirely without online communications, as data is typically routed through multiple cables to avoid overreliance on a single one. Cinia, the state-controlled Finnish company that oversees the second cable, said it wasnt yet determined what caused the outage since they havent yet physically inspected it. However, the sudden outage reportedly suggests it, too, was cut by an outside force. The foreign ministers of Finland and Germany released a joint statement on Monday. We are deeply concerned about the severed undersea cable connecting Finland and Germany in the Baltic Sea, they wrote. The fact that such an incident immediately raises suspicions of intentional damage speaks volumes about the volatility of our times. A thorough investigation is underway. Our European security is not only under threat from Russias war of aggression against Ukraine, but also from hybrid warfare by malicious actors. Safeguarding our shared critical infrastructure is vital to our security and the resilience of our societies. The Lithuania-Sweden cable, which handles about a third of Lithuanias internet capacity, is expected to be repaired over the next few weeks, and weather could determine the precise timing.This article originally appeared on Engadget at https://www.engadget.com/computing/two-baltic-sea-communications-cables-have-been-knocked-offline-214130723.html?src=rss

A four-pack of Samsung Galaxy SmartTag2 trackers are on sale via Amazon for just under $62. This Black Friday deal brings this particular combo pack down to a record low price. The typical cost is $100, so this represents a discount of 38 percent. This is one of our favorite Bluetooth trackers, and with good reason. They are the perfect companion accessory to Samsung phones. The finding network is vast and the battery life is fantastic. These trackers will stay powered on for up to 500 days, or even longer with Power Saving Mode enabled. We also appreciate the simple, yet aesthetically pleasing, design. Theres an actual hole for keychains, which is something Apple AirTags lack. These trackers are IP67-rated for water and dust-resistance. This means that the unit is protected from dust thats larger than 1mm in diameter and that it can be submerged in water up to one meter deep for up to 30 minutes. Just dont throw it in a lake and you should be good to go. The four-pack includes two white tags and two black tags, for a little yin and yang action. Theres not really a serious downside here for Samsung users. However, theres a major caveat for everyone else. The SmartTag2 trackers only work with Samsung phones and tablets. Check out all of the latest Black Friday and Cyber Monday deals here.This article originally appeared on Engadget at https://www.engadget.com/deals/a-four-pack-of-samsung-galaxy-smarttag2-trackers-is-38-percent-off-for-black-friday-194307496.html?src=rss

When Cray Computing, a supercomputer manufacturer acquired by HP in 2019, announced that it would build El Capitan it expected the computer to reach a peak performance of 1.5 exaflops. Today, the 64th edition of the TOP500 a long-running ranking of the world's non-distributed supercomputers was published, and El Capitan not only exceeded that forecast by clocking 1.742 exaflops, but has claimed the title as the most powerful supercomputer in the world right now. El Capitan is only the third exascale computer, meaning it can perform more than a quintillion calculations in a second. The other two, called Frontier and Aurora, claim the second and third place slots on the TOP500 now. Unsurprisingly, all of these massive machines live within government research facilities: El Capitan is housed at Lawrence Livermore National Laboratory; Frontier is at Oak Ridge National Laboratory; Argonne National Laboratory claims Aurora. Cray had a hand in all three systems. El Capitan has more than 11 million combined CPU and GPU cores based on AMD 4th-gen EPYC processors. These 24-core processors are rated at 1.8GHz each and have AMD Instinct M1300A APUs. It's also relatively efficient, as such systems go, squeezing out an estimated 58.89 Gigaflops per watt. If youre wondering what El Capitan is built for, the answer is addressing nuclear stockpile safety, but it can also be used for nuclear counterterrorism. Being more powerful than anticipated, its likely to occupy the throne for a long while before another exascale computer overtakes it.This article originally appeared on Engadget at https://www.engadget.com/computing/el-capitan-ranked-the-most-powerful-supercomputer-in-the-world-180037304.html?src=rss
