The former Trump adviser whose remarks in a London pub sparked the US inquiry into possible collusion with Russia has been sentenced to 14 days in jail. George Papadopoulos, 31, told the court in Washington DC he was a "patriotic American" who made a mistake by lying. He pleaded guilty last October to lying to the FBI about the timing of meetings with alleged go-betweens for Moscow. He was the first former Trump aide arrested in the probe into an alleged Kremlin plot to sway the 2016 US vote. US President Donald Trump reacted by taking an apparent swipe at the cost of the investigation into the former aide. In Friday's sentencing, Papadopoulos was also handed 12 months of supervised release, 200 hours of community service, and a fine of $9,500 (£7,350). He said in court that his "entire life has been turned upside down" and he hoped "for a second chance to redeem myself". Papadopoulos concluded by saying "this investigation has global implications, and the truth matters". Who is George Papadopoulos? The Chicago native was a London-based petroleum analyst before he joined the Trump campaign in March 2016 as a volunteer foreign policy adviser. Papadopoulos soon made contact with a mysterious Maltese academic, Joseph Mifsud. The professor told Papadopoulos the Russians had "dirt" on Mr Trump's Democratic presidential rival Hillary Clinton in the form of "thousands of emails". The young political operative told Mr Trump, then a Republican presidential candidate, and other members of the campaign's national security team that he could set up a meeting with President Vladimir Putin ahead of the November 2016 election. A pre-sentencing statement last week read: "While some in the room rebuffed George's offer, Mr Trump nodded with approval and deferred to Mr Sessions, who appeared to like the idea and stated that the campaign should look into it." Papadopoulos told CNN in an interview aired on Friday that Mr Trump "gave me a sort of a nod" and "wasn't committed either way" about the idea of a meeting with the Russian leader. But he said then-senator and now-Attorney General Jeff Sessions "was actually enthusiastic". Last November, Mr Sessions testified to Congress that he had "pushed back" against Papadopoulos' offer. How did this come out? American authorities were alerted in mid-2016 after Papadopoulos told an Australian diplomat during a drinking session in a London pub about his meetings with Professor Mifsud. The envoy alerted US investigators. When the FBI interviewed him in January 2017, Papadopoulos falsely claimed he had met two individuals with Russian ties before he joined the president's team in March 2016. He had actually met them after joining Mr Trump's campaign. One individual was a Russian woman who Papadopoulos believed had connections to the Russian government. Outside court on Friday, Papadopoulos' lawyer, Thomas Breen, said his client was a "fool" and had acted "stupidly" in lying to the FBI. But the attorney said "the president of the United States hindered this investigation more than Papadopoulos ever could". He said Mr Trump had hampered the inquiry by calling it a "witch hunt" and "fake news".

At least 10 people have been killed by Typhoon Jebi, the worst storm to hit Japan in 25 years. Jebi left a trail of destruction across the west of the country, hitting major cities like Kyoto and Osaka. Flights, trains and ferries were cancelled but thousands of passengers stranded at Osaka's international airport have since been evacuated. As the winds slow down and move north, people are being urged to stay alert for landslides and floods. At least 300 people have been injured as a result of the typhoon, according to government spokesman Yoshihide Suga. As of Wednesday morning, evacuation advisories had been issued for more than 1.2 million people. More than 30,000 people were given stronger but still not mandatory evacuation orders, the Fire and Disaster Management Agency said. Footage on social media showed the 100-metre (328-foot) tall ferris wheel in Osaka spinning rapidly in the storm despite being switched off. More than two million households experienced blackouts during the storm and schools and companies in the affected area remained shut. Nearly 800 flights were cancelled, including international flights at Nagoya and Osaka. On Wednesday, travellers stranded at Osaka's Kansai International Airport were being ferried by boat to another local airport. As many as 3,000 people had been stranded at the airport, which is built on an artificial island, after a tanker crashed into the bridge connecting it with the mainland. The airport had seen its runways and basements flooded and will remain closed all Wednesday.

A fire has gutted the National Museum of Brazil in Rio de Janeiro, the oldest scientific institution in the country. Most of its collection, including fossils, artworks and documents spanning centuries, is believed to have been destroyed. Firefighters are working to put out the blaze. No injuries have been reported. The museum, which once served as the residence for the Portuguese royal family, celebrated its 200th anniversary this year. The fire started on Sunday evening, after the facility had closed for the day. The cause is not known. Aerial images broadcast on Brazilian television showed it spreading throughout the building. Brazil's President Michel Temer said in a tweet that it was a "sad day for all Brazilians" as "200 years of work, research and knowledge were lost". The burning issue of a Rio in crisis By Katy Watson, BBC South America correspondent This isn't just Brazilian history that's gone up in flames. Many see this as a metaphor for the city - and the country as a whole. Rio de Janeiro is in crisis. Growing violence, a deep economic decline and political corruption have combined to make the city a shadow of what it once was. It was only in 2016 that it was hosting the Olympic Games - an event into which Brazil poured billions of dollars. But the hangover from the sporting event has hit Rio hard. Add to that the fact that federal spending has been slashed, and with violence on the rise, tourism numbers have also declined. This was a museum that many saw as long ignored and underfunded - now, with devastating consequences for Brazil's heritage. What did the museum contain? Among the 20 million items it housed were archaeological artefacts, fossils and the largest meteorite discovered in the country. The natural history collection included dinosaur bones and a 12,000-year-old skeleton of a woman known as "Luzia", the oldest ever found in the Americas. The building was also home to historical documents covering the centuries from the arrival of the Portuguese in the 1500s to the declaration of a republic in 1889. Portugal's royal family transferred the court to the building in 1808, when the country faced with the threat of invasion from Napoleon. Art and artefacts from Greco-Roman times and Egypt were also on display at the museum. What has the reaction been? Marcelo Moreira - a journalist with TV Globo in Rio - told the BBC: "It's very sad... This museum has a great history. It represents a lot for Brazilian history and Brazilian culture. It's really a big loss for Brazil." In an interview with Globo, the museum's director said it was a "cultural tragedy". One museum employee told the network that project managers had had "tremendous difficulty" trying to secure funding for "sufficient" resources for the palace. Another, librarian Edson Vargas da Silva, is quoted by local media describing the building, which he said had wooden floors and contained "a lot of things that burn very fast", such as paper documents. Employees had reportedly previously expressed concern about funding cuts and the dilapidated state of the building. The institution was established in 1818 as the Royal Museum with the aim of promoting scientific research by making its collection available to specialists.

If you liked the look, feel and light weight of the X1 Carbon, but want a more powerful system with a larger screen, Lenovo's upcoming ThinkPad X1 Extreme could be your answer. Due out in September for a starting price of $1,859, the X1 Extreme offers a 15-inch screen that's up to 4K resolution, a CPU that goes up to Core i9 and Nvidia GTX 1050 Ti dedicated graphics. The raven-black mobile workstation weighs just 3.76 pounds with its base-level, 1080p screen. That's about half a pound lighter than the Dell XPS 15 and a quarter pound less than the MacBook Pro 15. That weight jumps up to 4.04 pounds when you choose the optional, 4K touch screen. Considering the components it packs inside, the X1 Extreme is a mere 0.72 inches thick. While not as thin as some competitors, that leaves room for two full-size, USB Type-A ports, dual Thunderbolt 3 ports, an SD card reader and HDMI out. We haven't had a chance to test out the 4K screen, but if it's anything like the 2K HDR panel on the X1 Carbon, it will be one of the best displays on the market. Lenovo claims that, like the Carbon's high-end display, the Extreme's panel will support Dolby Vision HDR and reach up to 400 nits of brightness. It will also add touch capability, something the Carbon's HDR display lacks. The default, 1080p panel promises 300 nits of brightness. In addition to the high-end display, the X1 Extreme packs Nvidia GTX 1050 Ti graphics with 4GB of video memory. The GPU uses Nvidia's MaxQ technology, which allows it to run cooler and quieter (read: less fan noise), but which also limits performance somewhat. The system is powered by a 6-core, 45-watt Intel H Series processor. It will be available with Core i5, Core i7 and -- later in the year -- Core i9. The Extreme also supports up to 64GB of RAM. Lenovo's powerhouse laptop has room for two M.2 NVMe storage drives. You'll be able to get it with dual 1TB drives in a RAID 0 or RAID 1 array, which is a feature we've mostly only seen on gaming laptops before. Creative professionals and high-end users who want the same svelte chassis as the X1 Extreme but need a professional Nvidia Quadro card and Intel Xeon CPU should look into the ThinkPad P1, which will start at $1,949.

Nvidia’s Director of Technical Marketing, Tom Peterson, joined HotHardware on its 2.5 Geeks podcast yesterday and revealed details about the upcoming RTX 20-series graphics cards that Nvidia had hitherto kept secret. He talked about the Turing architecture’s Tensor Cores and RT Cores, he explained more about the Deep Learning Super Sampling technology, and perhaps most importantly, he admitted that Nvidia “could have done a better job” highlighting the performance of the new GPUs. He also talked somewhat candidly about what kind of performance gains that we could expect with the GTX 2080 cards. Nvidia spent most of its press event discussing ray tracing technology and the performance gains that the Turing-based cards bring to the table for that task. The company spent no time highlighting how well the new cards would handle existing games, though it followed up a few days later with a performance chart that suggests high generation-to-generation performance gains. During the Q&A with HotHardware, Peterson said that Turing is a “beast” and that “if you are on high-resolution and not CPU limited” you could expect to see between 35 percent and 45 percent performance gains in existing games when you step up from a GTX 1080 to an RTX 2080. And when queried about the RTX 2080 outperforming the GTX 1080 Ti, he said that he thinks there would be cases that would happen but couldn’t say for sure. On Deep Learning Super Sampling Deep Learning Super Sampling (DLSS) is a new technology that Nvidia introduced with the Turing architecture. The company didn’t explain the inner workings of the process, but the basic idea is that DLSS uses an AI algorithm to increase the resolution of your video output to improve the image quality. Nvidia said this technology improves performance compared to other super sampling and antialiasing technologies. HotHardware asked Petersen what DLSS does and how its delivered to gamers. He didn’t go deep into the details, but Petersen explained that there are two methods for developers to implement DLSS. They could create a custom algorithm which runs natively on the Tensor Cores, or Nvidia can pump the game code through a Saturn V supercomputer to allow a neural net to create the algorithm for the developer. For that reason, DLSS will be largely used by AAA studios that have relationships with Nvidia, though Petersen said the company is working on “a lot of games and not everything is AAA titles.” On NVLink Nvidia Turing is the first GPU architecture to embrace the company’s NVLink bridge technology, which offers higher bandwidth data transfer than the traditional SLI bridge. At Siggraph, where Nvidia launched Turing and the Quadro RTX lineup, the company revealed that NVLink enables frame buffer scaling. In traditional SLI, each card needs the same data in its memory pool. With Quadro RTX cards, NVLink combines the memory of each card to create a single, larger memory pool. Petersen explained that this would not be the case for GeForce RTX cards. The NVLink interface would allow such a use case, but developers would need to build their software around that function. “While it's true this is a memory to memory link; I don't think of it as magically doubling the frame buffer. It's more nuanced than that today,” said Petersen. “It's going to take time for people to understand how people think of mGPU setup and maybe they will look at new techniques. NVLink is laying a foundation for future mGPU setup.” NVLink’s current implementation offers higher bandwidth, which should improve performance, but it’s not a fix-all solution. Anyone who’s used an SLI setup would be familiar with the dreaded micro-stutter. Unfortunately, it appears the new bridge doesn’t completely solve that problem. Not yet, at least. Petersen said that the stuttering issue has more to do with alternate frame rendering (AFR), which is the current rendering technique for SLI. Nvidia is working on new mGPU technologies that would improve scaling in the future, but the company isn’t at liberty to discuss those yet. Overclocking HotHardware also asked Peterson about overclocking performance, to which he said, “it’s really good!” Nvidia built the power and cooling solutions of the Founder’s Edition cards specifically for overclocking, and Petersen said he'd seen 2.1Ghz on multiple cards, which suggests that at least the FE cards would be strong overclockers. Petersen also mentioned Nvidia Scanner and GPU Boost 4.0, of which we know nothing about yet.
