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."
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.

Doctors visited the White House 8 times? White House: Biden did not receive treatment for Parkinson's disease
White House spokeswoman Karina Jean-Pierre denied a report in the U.S. media on the 8th that President Joseph Biden did not receive treatment for Parkinson's disease. Biden had the first televised debate of the 2024 presidential election with Republican opponent Donald Trump on June 27, and his poor performance on the spot triggered discussions about his physical condition. The New York Times reported that a doctor specializing in the treatment of Parkinson's disease had "visited" the White House eight times from August last year to March this year. Facing the media's questions about Biden's health, Jean-Pierre asked and answered himself at a regular White House press conference on the 8th: "Has the president received treatment for Parkinson's disease? No. Is he currently receiving treatment for Parkinson's disease? No, he is not. Is he taking medication for Parkinson's disease? No." Jean-Pierre said Biden had seen a neurologist three times, all related to his annual physical examination. She also took out the report issued by the doctor after Biden's most recent physical examination in February this year. The report said, "An extremely detailed neurological examination was once again reassuring" because no symptoms consistent with stroke, multiple sclerosis or Parkinson's disease were found. The doctor who went to the White House mentioned by the New York Times is Kevin Kanal, a neurology and movement disorder expert at the Walter Reed National Military Medical Center in Maryland and an authority on Parkinson's disease. Jean-Pierre suggested that the doctor might have come to treat military personnel on duty at the White House.
Diphtheria outbreak in Vietnam kills one person
On the afternoon of July 8, local time, the Vietnamese Ministry of Health issued a notice stating that an 18-year-old girl in the country died of diphtheria. The Ministry of Health asked Nghe An Province and Bac Giang Province to take urgent action to control the epidemic. Diphtheria is an acute respiratory infectious disease caused by Corynebacterium diphtheriae, which is mainly transmitted through droplets and can also be indirectly transmitted by contact with objects containing Corynebacterium diphtheriae. Severe cases may show symptoms of poisoning throughout the body, complicated by myocarditis and peripheral nerve paralysis.
