Google extends Linux kernel support to 4 years

According to AndroidAuthority, the Linux kernel used by Android devices is mostly derived from Google's Android Universal Kernel (ACK) branch, which is created from the Android mainline kernel branch when new LTS versions are released upstream. For example, when kernel version 6.6 is announced as the latest LTS release, an ACK branch for Android15-6.6 appears shortly after, with the "android15" in the name referring to the Android version of the kernel (in this case, Android 15).

Google maintains its own set of LTS kernel branches for three main reasons. First, Google can integrate upstream features that have not yet been released into the ACK branch by backporting or picking, so as to meet the specific needs of Android. Second, Google can include some features that are being developed upstream in the ACK branch ahead of time, making it available for Android devices as early as possible. Finally, Google can add some vendor or original equipment manufacturer (OEM) features for other Android partners to use.

Once created, Google continues to update the ACK branch to include not only bug fixes for Android specific code, but also to integrate the LTS merge content of the upstream kernel branch. For example, the Linux kernel vulnerability disclosed in the July 2024 Android security bulletin will be fixed through these updates.

However, it is not easy to distinguish a bug fix from other bug fixes, as a patch that fixes a bug may also accidentally plug a security vulnerability that the submitter did not know about or chose not to disclose. Google does its best to recognize this, but it inevitably misses the mark, resulting in bug fixes for the upstream Linux kernel being released months before Android devices. As a result, Google has been urging Android vendors to regularly update the LTS kernel to avoid being caught off guard by unexpectedly disclosed security vulnerabilities.

Clearly, the LTS version of the Linux kernel is critical to the security of Android devices, helping Google and vendors deal with known and unknown security vulnerabilities. The longer the support period, the more timely security updates Google and vendors can provide to devices.

Insurers fret over militant attacks, AI hacks at Paris Olympics
LONDON, July 5 (Reuters) - Insurers are nervous that militant attacks or AI-generated fake images could derail the Paris Olympics, risking event cancellations and millions of dollars in claims. Insurers faced losses after the 2020 Tokyo Olympics were postponed for a year due to the COVID-19 pandemic. Since then, wars in Ukraine and Gaza and a spate of elections this year, including in France, have driven up fears of politically-motivated violence at high-profile global events. The Olympics take place in Paris from July 26-Aug 11 and the Paralympics from Aug 28-Sept 8. German insurer Allianz (ALVG.DE), opens new tab is insurance partner for the Games. Other insurers, such as the Lloyd's of London (SOLYD.UL) market, are also providing cover. "We are all aware of the geopolitical situation the world is in," said Eike Buergel, head of Allianz's Olympic and Paralympic programme. "We are convinced that the IOC (International Olympic Committee), Paris 2024 and the national organising committees, together with the French authorities, are taking the right measures when it comes to challenges on the ground."
Zuckerberg surfed and drank beer on vacation, Musk: I prefer to work
After Meta CEO Mark Zuckerberg posted a video on his Facebook and Instagram accounts of his free time during the Independence Day holiday on the X platform, Musk said, "I prefer to work." Zuckerberg posted a video of himself surfing on a hydrofoil in a tuxedo, waving an American flag and drinking a beer, and wrote: "Happy birthday America." The video quickly went viral, and after greg shared it on the X platform, Musk replied: "I hope he continues to have fun on the yacht." I prefer to work." Musk, a workaholic, attended the 29th annual Barron Investment Conference in November 2022, where he said: "My workload went from 78 hours a week to 120 hours a week..." In 2018, he slept on the floor of the Gigafactory in Fremont in an effort to ramp up production of the Tesla Model 3.
Koenigsegg Fused Three Hypercars Into One To Make The Chimera
Koenigsegg Agera RS Chimera combines technologies from Agera RS, CC850, and Jesko. An Agera RS platform features the engine from the Jesko and the simulated manual gearbox from the CC850. Development took three years, thanks to software and hardware integration challenges. A "chimera," for the uninitiated, is described as a mythical creature whose anatomy comes from multiple animals, creating a hybrid of two or more creatures' best bits. It's also the name of the latest one-off creation from Koenigsegg, and it's certainly apt; the Koenigsegg Agera RS Chimera is an amalgam of technologies from the decade-old, record-breaking Agera RS, the fascinatingly innovative CC850, and the awe-inspiring Jesko - which just recently set four new acceleration records. There's also a hint of Regera in here, which had some impressive records of its own. As reported by Mr. JWW, the strictly one-off special edition was commissioned by FIA President Mohammed Ben Sulayem, and both he and one of Koenigsegg's engineers arrived at the same name. Let's take a closer look and see exactly why this is a hybrid, even though it's not electrified. Three Cars In One The Chimera was originally a regular Agera RS and one of several Koenigsegg megacars owned by Ben Sulayem, but he asked Christian and the team to initiate a special project on his behalf. Around the same time, the extraordinary Koenigsegg CC850 was revealed at Monterey Car Week 2022, introducing the innovative Engage Shift System (ESS). This was based on the already astonishingly fast nine-speed Light Speed Transmission, with new actuators and sensors added to enable the simulation of a manual transmission without a physical link between the shifter and the gearbox. Like the rest of the world, the FIA boss was enamored by this novel technology, and as a wealthy 'Egg collector, he asked for it to be put into his special Agera-based project. Christian pondered this and ultimately decided to fulfill the request, in the process turning Ben Sulayem's special edition into something of a development mule for the ESS. But unlike the CC850, the Chimera got the larger turbos of the Jesko, enabling around 1,280 horsepower on regular gas and up to 1,600 hp on E85. That means this is an Agera RS with a CC850 transmission and a Jesko engine. On paper, that sounds simple, but the reality was anything but... Three Shifting Experiences Took Three Years To Combine According to a video from YouTuber and Koenigsegg distributor Mr. JWW, this development process took three years and required the relocation of the battery, new mounts for the powertrain, new harnesses, new software and controllers, and even a new infotainment system. To ensure all the electronics worked seamlessly was a challenge, but then Ben Sulayem asked for another layer of intricacy, requesting that paddle shifters be added, like in the Jesko Absolut and Jesko Attack. In the CC850, you could only switch between the simulated manual mode and fully automatic shifts, but now, the Chimera's development has unlocked manually operable paddles, which have now been added as the only option you can add to a CC850. There was also significant relocation and redesigning of suspension components, with parts from the Jesko and the Regera forming the subframe and elements of the suspension, respectively. A new scoop for the new transmission's cooler was also added, but it looks like it was always planned. Christian von Koenigsegg says this is a true one-off, saying that it would be cheaper and easier to start something all-new from scratch than to mix new and old technologies again, and that it's simply "too much work" to tackle a retrofit project. The Chimera is not completed just yet, as there are still subtle elements to refine, such as the bite point of the clutch pedal, but these minor issues will surely be resolved soon. It's an amazing feat, combining three hypercars in one, and we can't even fathom how Koenigsegg will top this in the future, but we don't doubt that Christian and his team will continue to do just that.
Ukrainian Presidential Office: Russia's attacks on multiple locations in Ukraine have killed 36 people
The Ukrainian presidential office said on July 8 local time that Russia's large-scale attacks on many parts of Ukraine have killed 36 people and injured 140 others. According to the Ukrainian State Emergency Service, a total of 619 rescue workers and 132 equipment participated in the rescue work across Ukraine that day. Ukrainian President Zelensky said on social media on the 8th that Russia launched more than 40 missiles of various types at Ukraine that day. Residential buildings and infrastructure in many cities in Ukraine were damaged in varying degrees of attacks, and a children's hospital was destroyed. Rescue departments are currently conducting emergency rescue on the scene. The Russian Ministry of Defense issued a statement on the 8th local time saying that Ukrainian officials' claim that Russia used missiles to attack Ukrainian civilian facilities was untrue. The damage suffered by Kiev was caused by the fall of missiles launched by the city's air defense system.
Exclusive: Nornickel in talks with China Copper to move smelting plant to China, sources say
HONG KONG, July 9 (Reuters) - Nornickel (GMKN.MM), opens new tab is in talks with China Copper to form a joint venture that would allow the Russian mining giant to move its entire copper smelting base to China, four sources with knowledge of the matter told Reuters. If the move goes ahead, it would mark Russia's first uprooting of a domestic plant since the U.S. and Britain banned metal exchanges from accepting new aluminium, copper and nickel produced by Russia. It also means Nornickel's copper will be produced within the country where it is most consumed. Nornickel said in April it planned to close its Arctic facility and build a new plant in China with an unnamed partner. Executives at China Copper, owned by the world's largest aluminium producer Chinalco (601600.SS), opens new tab, flew to Moscow in June to discuss a possible joint venture, one of the sources said, adding that details of the structure and investment are still under discussion. Nornickel declined to comment. Chinalco and China Copper did not respond to requests for comment via email and phone. Sites being considered in China include Fangchenggang and Qinzhou in the Guangxi region, the two sources said, with another source saying Qingdao in Shandong province was also possible. A decision on a joint venture will be made over the next few months, a fifth source said, adding that Nornickel's Chinese output is likely to be consumed domestically. The new facility will have capacity to produce 450,000 tonnes of copper annually, two of the sources said, amounting to around 2% of global mined supplies estimated at around 22 million metric tons this year. Nornickel, which according to its annual report produced 425,400 tonnes of refined copper last year, processed all of its concentrates in 2023 at the Arctic plant, its only operation producing finished copper suitable for delivery to exchanges.
