• 17/07/2025 - 17:57 Гость The bow of a US Navy cruiser damaged in a World War II battle in the Pacific has shone new light on one of the most remarkable stories in the service’s history. More than 80 years ago, the crew of the USS New Orleans, having been hit by a Japanese torpedo and losing scores of sailors, performed hasty repairs with coconut logs, before a 1,800-mile voyage across the Pacific in reverse. The front of the ship, or the bow, had sunk to the sea floor. But over the weekend, the Nautilus Live expedition from the Ocean Exploration Trust located it in 675 meters (2,214 feet) of water in Iron Bottom Sound in the Solomon Islands. a href=https://kra34g.cc kra34 cc /a Using remotely operated underwater vehicles, scientists and historians observed “details in the ship’s structure, painting, and anchor to positively identify the wreckage as New Orleans,” the expedition’s website said. On November 30, 1942, New Orleans was struck on its portside bow during the Battle of Tassafaronga, off Guadalcanal island, according to an official Navy report of the incident. https://kra34g.cc кракен The torpedo’s explosion ignited ammunition in the New Orleans’ forward ammunition magazine, severing the first 20% of the 588-foot warship and killing more than 180 of its 900 crew members, records state. The crew worked to close off bulkheads to prevent flooding in the rest of the ship, and it limped into the harbor on the island of Tulagi, where sailors went into the jungle to get repair supplies. “Camouflaging their ship from air attack, the crew jury-rigged a bow of coconut logs,” a US Navy account states. With that makeshift bow, the ship steamed – in reverse – some 1,800 miles across the Pacific to Australia for sturdier repairs, according to an account from the National World War II Museum in Louisiana. Retired US Navy Capt. Carl Schuster described to CNN the remarkable skill involved in sailing a warship backwards for that extended distance. “‘Difficult’ does not adequately describe the challenge,” Schuster said. While a ship’s bow is designed to cut through waves, the stern is not, meaning wave action lifts and drops the stern with each trough, he said. When the stern rises, rudders lose bite in the water, making steering more difficult, Schuster said. And losing the front portion of the ship changes the ship’s center of maneuverability, or its “pivot point,” he said. “That affects how the ship responds to sea and wind effects and changes the ship’s response to rudder and propellor actions,” he said. The New Orleans’ officers would have had to learn – on the go – a whole new set of actions and commands to keep it stable and moving in the right direction, he said. The ingenuity and adaptiveness that saved the New Orleans at the Battle of Tassafaronga enabled it to be a force later in the war.
• 17/07/2025 - 17:42 Гость “AI expends a lot of energy being polite, especially if the user is polite, saying ‘please’ and ‘thank you,’” a href=https://tripscan.biz трипскан сайт /a Dauner explained. “But this just makes their responses even longer, expending more energy to generate each word.” For this reason, Dauner suggests users be more straightforward when communicating with AI models. Specify the length of the answer you want and limit it to one or two sentences, or say you don’t need an explanation at all. Most important, Dauner’s study highlights that not all AI models are created equally, said Sasha Luccioni, the climate lead at AI company Hugging Face, in an email. Users looking to reduce their carbon footprint can be more intentional about which model they chose for which task. “Task-specific models are often much smaller and more efficient, and just as good at any context-specific task,” Luccioni explained. https://tripscan.biz tripscan If you are a software engineer who solves complex coding problems every day, an AI model suited for coding may be necessary. But for the average high school student who wants help with homework, relying on powerful AI tools is like using a nuclear-powered digital calculator. Even within the same AI company, different model offerings can vary in their reasoning power, so research what capabilities best suit your needs, Dauner said. When possible, Luccioni recommends going back to basic sources — online encyclopedias and phone calculators — to accomplish simple tasks. Why it’s hard to measure AI’s environmental impact Putting a number on the environmental impact of AI has proved challenging. The study noted that energy consumption can vary based on the user’s proximity to local energy grids and the hardware used to run AI models. That’s partly why the researchers chose to represent carbon emissions within a range, Dauner said. Furthermore, many AI companies don’t share information about their energy consumption — or details like server size or optimization techniques that could help researchers estimate energy consumption, said Shaolei Ren, an associate professor of electrical and computer engineering at the University of California, Riverside who studies AI’s water consumption. “You can’t really say AI consumes this much energy or water on average — that’s just not meaningful. We need to look at each individual model and then (examine what it uses) for each task,” Ren said. One way AI companies could be more transparent is by disclosing the amount of carbon emissions associated with each prompt, Dauner suggested.
• 17/07/2025 - 17:20 Гость Guatemala has pledged a 40% increase in deportation flights carrying Guatemalans and migrants of other nationalities from the United States, President Bernardo Arevalo announced Wednesday during a press conference with US Secretary of State Marco Rubio. a href=https://kra-39at.com kra40.cc /a Guatemala has also agreed to create a task force for border control and protection along the country’s eastern borders. The force, composed of members of the National Police and army, will be tasked with fighting “all forms of transnational crime,” Arevalo said. a href=https://kra31-at.com кракен сайт купить /a Foreign nationals who arrive in Guatemala through deportation flights will be repatriated to their home countries, Arevalo said, adding that the US and Guatemala would continue to have talks on how the process would work and how the US would cooperate. a href=https://kra31-cc.net kra50 cc /a Arevalo also said that Rubio has voiced his support for developing infrastructure projects in the Central American nation. He added that his government would send a delegation to Washington in the coming weeks to negotiate deals for economic investments in Guatemala – which he said would incentivize Guatemalans to stay in their home country and not migrate to the US. Arevalo said Guatemala has not had any discussions about receiving criminals from the US as El Salvador’s president has offered. He also insisted his country has not reached a “safe third country” agreement with the United States, which would require migrants who pass through Guatemala to apply for asylum there rather than continuing to the US. kra39.at https://kra-39cc.com
