The opening ceremony of the Beijing Winter Olympics shocked the screen

On February 4th, the opening ceremony of the 2022 Beijing Winter Olympics was successfully held. In this Spring Festival, an unparalleled visual feast was presented to the people of the world. Zhang Yimou, the chief director of the opening ceremony of the Beijing Winter Olympics, used four words to describe tonight's opening ceremony "ethereal, romantic, modern, and technological." According to him, the opening ceremony and the ignition of the Beijing Winter Olympics are all stories of snowflakes. Completely different snowflakes converge in Beijing and become a human snowflake.

The opening ceremony of the Beijing Winter Olympics used digital performance and simulation technology throughout the whole process. It was first simulated in the virtual Bird's Nest (National Stadium), and finally landed in the real world. Through the comprehensive use of artificial intelligence, 5G, AR, naked eye 3D and Cloud and other scientific and technological achievements have achieved the effect of "few people but not empty, ethereal and romantic".

This is also the world's first large-scale application of 8K technology for the live broadcast of the opening ceremony and the coverage of key events. It will combine with the 5G network to present an immersive visual feast of ice and snow.

In addition, for the first time, the entire Bird's Nest super-large ground screen has realized full LED image to replace the traditional ground screen projection, and the picture quality reaches 16K. In the 5-month high-intensity rehearsal and the extremely low temperature rain and snow weather of minus 30 degrees Celsius in winter, the ground display system can still achieve stable operation, perfectly presenting the dreamy and realistic beauty of technology to the world.

Microsoft disables MSIXAppX installer

Microsoft officially announced today that it has disabled the MSIX application installer protocol to prevent malicious attacks. This protocol allows users to install various applications directly from web servers without first downloading them to local storage. The thinking at the time was that this approach would save space for the user, since there would be no need to download the entire MSIX package.

However, this Windows application installer was later found to be used to distribute malicious PDF files such as the Emotet and BazarLoader malware. As such, the protocol was disabled last year, but was only officially announced today. This Windows AppX Installer Spoofing vulnerability has been assigned the ID CVE-2021-43890.

Ministry of Industry and Information Technology: The opening ceremony of the Winter Olympics was successfully completed, and more than 4,000 IP addresses of malicious programs were blocked.

On the evening of February 4, the world-renowned Beijing Winter Olympics opening ceremony was held at the National Stadium "Bird's Nest". The Ministry of Industry and Information Technology successfully completed the tasks of radio security, information communication and network security at the opening ceremony of the Winter Olympics.

According to the introduction of Gongxin Weibo, during the opening ceremony, the radio frequency of each unit was used in an orderly manner, and more than 48,000 sets of radio equipment were working normally, realizing "zero interference, zero error, and zero defect" in radio security.

Intel says its CPU bugs are half of AMD's

According to Tom's Hardware, Intel said its CPUs reported 16 vulnerabilities in 2021, compared to 31 for AMD processors.

Intel said its CPUs reported 16 security flaws in 2021, six of which were discovered by researchers in a bug bounty program and 10 were discovered within the company. On the GPU side, 15 vulnerabilities were discovered internally by Intel, while 36 were discovered through the bug bounty program.

Data shows that nearly half of Intel's GPU vulnerabilities come from Intel's use of AMD GPU components in its own chips. Intel noted that Intel Core processors with Radeon RX Vega M graphics have vulnerabilities in 23 AMD components. The most vulnerable models are Dell XPS 15 laptops and Hades Canyon NUCs. While the flaws are said to appear on Intel chips, the flaws arose from AMD's technology.

GitHub launches sponsorship feature: you can tip your favorite projects and set up paid access

GitHub has been encouraging users to financially support their favorite software projects, and now GitHub is rolling out a donation feature for projects.

GitHub already allows developers to add donation links to their projects, or developers can register companies to add a "GitHub Sponsorship" feature.

GitHub says post-sponsored-access-only repositories can be used for early access or beta testing, or as tickets to forum-like discussions, for which developers can set their own amounts.

Google Chrome logo changes for the first time in 8 years: Simpler, brighter

For the first time in eight years, Google has changed its Chrome browser's logo with a simpler look designed to better match Google's current branding, but you might not have noticed. Its overall scheme is the same as the circular, four-color basic design of the first Chrome browser in 2009, which Google flattened out in a 2011 revamp, a company designer said Friday.

Google is also tweaking it further, with the design team arranging a series of different subtle changes to make it look more recognizable on Windows, MacOS, and iOS. For example, on Windows 10 and Windows 11, the color of the icon is gradient, starting from the bottom and getting darker. On ChromeOS, the colors are brighter. On MacOS, the icon has a 3D appearance, like a thin disk. Less noticeable is the slight change in green from the left to the bottom. This is to avoid the harsh visual "vibration" that can occur when the brighter green is opposed to the red on top.

Apple plans to release new low-cost 5G iPhones and iPads in early March, sources say

Apple plans to launch a new low-cost iPhone and an upgraded iPad on or around March 8, according to people familiar with the matter. This will be Apple's first major event since the launch of the new MacBook Pro last October. Like other recent Apple product launches, the launch is expected to be online, according to people familiar with the matter. The people familiar with the matter declined to be named as the information is not public.

Redis DesktopManager 2022.0 released, project renamed RESP.app

While the Raspberry Pi 3 has a 64-bit Cortex CPU core, and even the Raspberry Pi Zero 2 supports 64-bit, Raspbian OS, the official operating system for the Raspberry Pi, is still a 32-bit system. Finally in 2022, Raspbian OS has launched an official 64-bit version.

This 64-bit Raspberry Pi operating system has been tested over the past year and is now determined to be in good condition for customers to use on newer Raspberry Pi boards as a replacement for its 32-bit version.

Compatibility is a key issue for developing the 64-bit Raspbian OS: many closed-source applications are only available for arm64, and open-source applications are not fully optimized for the armhf port.

In addition to this, the A64 instruction set has some inherent performance advantages, as 32-bit pointers only allow addressing of 4GB of memory. But on the Raspberry Pi 4, ARM Large Physical Address Extensions (LPAE) are required to access up to 8GB of memory, so the addressing capabilities of a 64-bit system provide better performance for single-process applications that consume a lot of memory.
