The verdict of the former vice president of Kuaishou for a huge bribe was announced
More than a year after the arrest of Zhao Danyang, the former vice president of Kuaishou, the case was finally pronounced.
According to the first-instance judgment published by the Beijing Court Trial Information Network, the total amount involved in Zhao Danyang's case was more than 7.56 million yuan.
Judging from the content of the judgment, between June 2015 and March 2019, Zhao Danyang took advantage of his position in charge of the Kuaishou content rating department to use the bank account provided by his mistress Qiao Jun to accept a total of RMB6,681,054.69 in benefit fees from Zheng Mou, the head of Yancheng Outsourcing Company.
The first-instance judgment was as follows: Zhao Danyang was sentenced to 7 years' imprisonment in the first instance for accepting bribes from non-state workers and for embezzlement of office; Qiao Jun was sentenced to 4 years' imprisonment for concealing and concealing the proceeds of crime.
Li Lei, a subordinate of Zhao Danyang, was convicted of usurpation of office and sentenced to one year and seven months in prison and fined 100,000 yuan.
Zhao Danyang's bribery arrest was the first time since Kuaishou's establishment that it had publicly disclosed in an email that a company executive had been arrested for corruption.
NASA studies mapping the moon with lidar
NASA revealed that it is working with lidar company Aeva to develop a tool to scan lunar terrain when ordinary cameras and satellites can't meet the requirements.
The project is called KNaCK, or Kinematic Navigation and Cartography Knapsack, which is an ultra-precise ranging system based on the concept of synchronous positioning and cartography.
While there is something like GPS on Earth, there is no such thing as space. High-resolution surface images from orbiting satellites are not sufficient for space navigation.
For example, at the south pole of the moon, due to the fixed angle of the sun's illumination, there is a part of the shadow area that will never be illuminated.
Lidar offers an option to map even in dark environments or in bright sunlight. Currently, it is already being used in devices such as landers.
Currently, NASA and Aeva are developing a mapping tool that is small enough for astronauts to carry on a backpack or placed on a rover as one of the devices. It is capable of scanning terrain and generating detailed maps in real time.
Compared with other similar systems, Aeva lidar has the advantage of being able to capture the velocity vector of a certain point and is highly resistant to light.
The "privatized Tesla" tweet was convicted of false information, and Musk sought appeal
Recently, San Francisco's U.S. District Judge Edward M. Chen found Musk's tweet about "privatizing Tesla" in 2018 to be false information.
Tesla shareholders, who are the plaintiffs, claim that musk's tweet and subsequent tweets released in August 2018 caused them to lose billions of dollars in the face of tesla's stock price ups and downs.
Musk is currently preparing to appeal the judge's ruling.
Musk's lawyers said the court must consider that the statements were made on social media rather than in regulatory documents when analyzing whether a statement was misleading.
The smart summon function caused trouble, and Tesla cars crashed into private planes
According to Reddit users, a Tesla Model Y car crashed into a $3.5 million private jet when the "smart summoning" function was enabled.
The user said that at that time, the Tesla owner enabled the smart summoning function, and as a result, his car slowly crashed into the Cirrus Vision jet and then continued to push the aircraft around.
Tesla's smart summoning function, which uses an external camera to identify the surrounding environment and objects, is designed to allow Tesla cars to leave the parking space and bypass obstacles to reach the owner's location under the remote control of a human mobile phone.
The feature was first introduced in 2019, and Musk once called it Tesla's most compelling feature. Just a few weeks after its release, it was used more than 550,000 times.
But in fact, when the owner uses this function, he needs to always pay attention to the surrounding situation.
This isn't the first time the smart summon feature has led to a collision. Back in September 2019, a Tesla owner posted a video on Twitter saying that his Tesla almost crashed into another car after enabling the feature.
The Video Codec for Android phones found a key vulnerability
According to Ars Technica, researchers recently discovered a vulnerability that allowed hackers to control millions of Android devices equipped with Qualcomm and MediaTek mobile chipsets.
The vulnerability stems from ALAC, an audio format introduced by Apple that can be used to provide lossless audio on the Internet. While Apple has been updating its proprietary version of its decoder for years to fix security flaws, the open source version used by Qualcomm and MediaTek has not been updated since 2011.
Hackers can exploit this vulnerability to allow decoders to execute malicious code, such as remotely attacking mobile devices through special audio files, to control users' multimedia data.
Qualcomm and MediaTek have submitted patches to Google and manufacturers, and most manufacturers have provided patches to eligible users.
If Android users want to know if their device is patched, they can check the security patch level in the operating system settings. If the patch shows an update date of December 2021 or later, the vulnerability in the device has already been fixed.
CNNC launches nuclear-powered pet dogs
CNNC announced that its N-universe R&D team has recently developed a nuclear-powered pet dog "Mido" and announced its "chic" shape.
The dog is currently in the beta phase of the product and is scheduled to be brought to market in the near future.
After the product was announced, it immediately attracted netizens to watch, and some people expressed the hope that "Miduo" could generate nuclear power and help charge notebooks and mobile phones anytime and anywhere.
CNNC's official reply: The requirements have been submitted to the development team.
Some netizens hope to build a robot in "Fallout 4".
In 2020, CNNC released the first super universe in the nuclear field, the "N Universe".
Officially, this is to build an IP of the nuclear science fiction universe and carry out the creation of nuclear science fiction content for a long time and systematically, so as to enhance the public's interest and understanding of nuclear science and technology.
