Industry Information

The official website of the Didi Travel App has been removed from the shelves and cannot be downloaded at all

Recently, according to the State Cyberspace Administration of China, the Didi Travel App has been removed due to serious violations of laws and regulations in collecting and using personal information. The official announcement shows that according to the report, after testing and verification, the "Didi Travel" app has serious violations of laws and regulations in collecting and using personal information.

In accordance with the relevant provisions of the "Network Security Law of the People's Republic of China", the State Internet Information Office notified the app store to remove the "Didi Travel" app, and required Didi Travel Technology Co., Ltd. to strictly follow the legal requirements and refer to the relevant national standards to seriously rectify existing problems. , To effectively protect the personal information security of the vast number of users.

The search found that in addition to the Apple App Store and major domestic Android app stores, the "Didi Travel" app on Didi's official website today has also disappeared.

However, users can still download the Didi Enterprise Edition, while the Didi International Edition needs to log in to the Google Play store to download. In addition, the WeChat/Alipay applet of "Didi Travel" has also been removed.

Prior to this, the National Cyberspace Administration of China stated that in order to prevent national data security risks, maintain national security, and protect public interests, it will conduct cybersecurity reviews on Didi Travel in accordance with the law. In order to cooperate with the network security review work and prevent risks from expanding, “Didi Travel” stopped new user registration during the review period.

It is reported that Apple's M2 chip will be postponed to next year or be carried by the new MacBook Air

According to foreign media reports, Apple's M2 chip may be delayed until early 2022 or the first half of 2022, and may be carried by the new MacBook Air for the first time.

Dong Mingzhu: Gree will introduce Hongmeng operating system

According to data released by Huawei, the latest Harmony OS 2 has just come out a month ago. Up to now, it has supported as many as 69 terminal products, and more than 25 million users have completed the upgrade. It can be said that with the acceleration of the official adaptation progress and users' enthusiasm for upgrading the Hongmeng system, Huawei's Hongmeng operating system is accelerating its development with a vigorous momentum.

According to reports, Gree Electric’s chairman Dong Mingzhu recently publicly stated that “the Hongmeng operating system will be introduced in the future”. If this is the case, the follow-up Gree's smart home appliance products may be supported by the Hongmeng system ecosystem, which is believed to bring more diversified and convenient interactive experiences to users.

Win7/8.1 can be upgraded to Win11 for free, but applications, settings and other content will be deleted

It was reported on July 7 that Microsoft’s free upgrade benefits for Windows 7 and Windows 8.1 users ended as early as 2016, but users can still upgrade to Windows 10. Microsoft said it will continue to support upgrades from Windows 7 or Windows 8.1 to Windows 11, as long as they meet the minimum system requirements.

However, after Windows 7 is upgraded to Windows 11, the user's applications, settings, and custom functions may be deleted. This is because according to a support document issued by Lenovo on June 24, Windows 7/8.1 users do not have a suitable direct upgrade path.

A new support document from Lenovo India (the document is based on Microsoft's statement) indicates that users of Windows 7 and Windows 8/8.1 can also upgrade to Windows 11, but only with a clean install (clean install) or reimage (reimage). installation).

For those users who use Windows 10, if the hardware meets the requirements, they can upgrade to Windows 11 for free through traditional update channels-Windows Update, WSUS, media creation tools and update assistants.

The support document reads: "Most devices that can be purchased now will be upgraded to Windows 11. You will have the option to upgrade, clean install or reinstall Windows 10 devices to migrate to Windows 11. For Windows 7 devices that meet the hardware requirements , A clean installation or reinstallation is required to use Windows 11."

The early preview version of Windows 11 already includes configuration keys for Windows 7, 8 and 8.1, which will allow users to upgrade for free.

Of course, if users do not like the new Windows 11, they can downgrade to Windows 10 at any time. To downgrade to Windows 10 and retain files and data, users need to move back to Windows 10 during a 10-day window. If you downgrade after 10 days of installation, you need to manually back up your application and perform a clean installation.

Windows 11 and Windows 7 operating systems are very different, but Microsoft promises that existing applications will continue to work. The company said: "Windows 11 was built with compatibility in mind. Therefore, if applications work normally on Windows 7/8.1/10, they will continue to work normally on Windows 11."

"If you have App Assure [business-specific services], Microsoft will help you repair them for free," Microsoft pointed out in the same document.

Microsoft is currently planning to launch Windows 11 in the second half of this year, and we will learn more about hardware compatibility in the coming weeks/months.

Chen Mingyong, the founder of OPPO, leads the team to prepare for the car Liu Bo: It is not needed yet

The core configuration of the iPhone 13 series is exposed: the performance of the new A15 chip is fully improved

According to the latest information released by overseas experts, the new iPhone 13 series will be equipped with a new generation of A15 processor. The processor has already begun trial production, and the CPU will still adopt a design of two large cores + four small cores. There will be a 20% improvement over the A14, and it will be equipped with a 5-core GPU. It is expected that there will be at least a 35% performance upgrade. In addition, this processor will also use TSMC's N5P process, which will further increase performance at the process level and further reduce power consumption.

In other respects, according to previously exposed news, the new iPhone 13 series will still include four models: iPhone 13 mini, iPhone 13, iPhone 13 Pro and iPhone 13 Pro Max, all of which use a full-screen design with bangs, and the area of bangs has finally been obtained. Significantly reduced, the display effect finally usher in a breakthrough. Not only that, the iPhone 13 Pro series will also use Samsung’s 120Hz LTPO OLED panel, support 120Hz adaptive refresh rate, and bring intelligent adjustment of the screen refresh rate function, which can automatically switch between 1-120Hz according to the screen content, and also with Comes more power-saving effect, and supports Face ID and Touch ID dual unlocking scheme.

It is reported that the brand-new iPhone 13 series will continue to be unveiled in September this year. If not surprisingly, the screen upgrade will become the biggest part of this machine upgrade, and its price will also rise at the same time. The top version is expected to exceed 15,000. The price of yuan has become the most expensive iPhone in history.

Pixel 6 and Pixel 6 Pro "final specifications" leaked to provide 5 years of software updates

on Prosser released new information on FrontPageTech, revealing the expectations of Pixel 6 and Pixel 6 Pro in terms of internal specifications. The previous renderings show that Pixel 6 and Pixel 6 Pro will be different from any previous products released by Google. This is an excellent sign that the company hopes to target the high-end product line of the smartphone industry. Prosser announced the following details:

Google Pixel 6 (code-named Oriel)

Screen size: 6.4 inches

Display: AMOLED

Rear camera module: 50 million pixels (main camera) + 12 million pixels (wide angle)

Front camera: 8 million pixels

Battery: 4614mAh

Processor: Google Whitechapel (code name)

Memory: 8GB

storage. 128GB/256GB

Operating system: Android 12

Google Pixel 6 Pro (codenamed Raven)

Screen size: 6.71 inches

Display: Plastic OLED

Rear camera module: 50 million pixels (main camera) + 48 million pixels (telephoto) + 12 million pixels (wide angle).

Front camera: 12 million pixels

Battery: 5000mAh

Processor: Google Whitechapel (code name)

Memory: 12GB

Storage space: 128GB / 256GB / 512GB

Operating System: Android 12

These two flagship phones will use a custom solution code-named Whitechapel, which is expected to be a collaboration between Google and Samsung. It is said that the SoC will use the same GPU as the Exynos version of the Galaxy S21, namely ARM Mali-G78. An impressive feature rumored to bring to these two flagships is the gimbal mode, which will introduce a new and improved level of stability when shooting images or videos.

Pixel 6 and Pixel 6 Pro are also expected to be equipped with a custom neural processing unit.

The performance of Windows Terminal provokes controversy again, and the difficulty is equivalent to that of a PhD project?

Casey Muratori, a game engine developer and author of the Handmade Hero project, published an issue about WT performance in the GitHub repository of Windows Terminal (hereinafter referred to as WT), which sparked heated discussions.

Casey Muratori pointed out in the issue that WT is about 40 times slower than monochrome characters when rendering color characters, and attached the benchmark program TermBench for testing. Afterwards, Casey Muratori and WT members started a discussion under the issue, but did not reach a consensus. Casey Muratori was deemed "too simplistic as a doctoral research project", and the issue was subsequently closed.

Since then, Casey Muratori directly released a video titled "How fast should an unoptimized terminal run?" in its Handmade Hero channel. The video gives the corresponding reference implementation RefTerm as a comparison and describes the performance issues of WT in detail. The RefTerm supports rollback, line feed, Unicode combination, RTL-over-LTR, multi-color fonts, real-time font changes, and rendering speeds of several thousand FPS.

However, some developers questioned the RefTerm implemented by Casey Muratori in the video. Their opinions mainly include:

• Use the /GS- /Gs999999set command line parameters when building, which will disable security features and affect performance. The main job of the terminal application is to parse untrusted input.
• The application uses 0.5% of the CPU and up to 14% of the GPU to display the blinking cursor, which is not efficient. And the RefTerm application uses 351 MB of memory when it is idle (runs on a 4k monitor), and the acceptable memory usage of the terminal is about 10-20 MB.
• Insufficient reliability. The terminal is a high-risk application because it must parse a large amount of untrusted text, and running splat refterm\_debug\_msvc.pdb in RefTerm will cause RefTerm to freeze immediately and consume 100% of the CPU. The application window cannot be closed, it can only be killed through the task manager.

Is GitHub forced to become an open source project by "GitHub Copilot"?

GitHub launched a tool called "GitHub Copilot" last week. This tool uses machine learning technology to provide code suggestions/auto-completion, which has caused a lot of controversy. The reason is that many developers believe that the open code training that GitHub Copilot claims is actually "plagiarizing" open source code without following the open source license.

In order to protest against GitHub's unauthorized use of copyrighted source code as training data for GitHub Copilot, a few more radical developers announced the abandonment of GitHub.

Among the many questions and criticisms, one question that has been discussed more is: If the training model of GitHub Copilot uses GPL-compliant software for training, what will happen?

The latest technology trends

The patch to add Rust support to the Linux kernel is ready

On July 4, a revised set of patches was submitted to the Linux kernel mailing list. The patch provided support for using Rust as an auxiliary programming language in the Linux kernel. With the help of Rust, the security of the Linux kernel and memory can be improved.

The whole set of patches contains 17 sub-items. It not only provides preliminary Rust support for the Linux kernel, but also provides a driver example, with a total of more than 33,000 lines of new code.

Miguel Ojeda has been leading the "Rust for Linux" work. Google previously funded the project to improve the security of the Linux kernel so that this programming language can be used in the kernel. Although the kernel merge of Linux 5.14 is still in progress, this set of patches is not currently marked as "Pull Request", so it is expected that this set of patches will not officially land on Linux until the next merge cycle.

The launch of Rust for Linux has now reached more than 33,000 lines of code. One of the reasons for including so much code is that a subset of Rust's "alloc" standard library is currently included in the data structure and added on this basis Some content. This allows developers to customize according to their needs. At the same time, provide upstream the required time to evaluate this change. The ultimate goal is to put everything the kernel needs in the upstream "alloc" and remove it from the kernel tree.

Another change of these new patches is that in the previous version, if you want to compile the Linux kernel, you need to use the nightly version of the Rust compiler, and now the kernel can use the Beta and stable versions of the Rust compiler. However, because the support for the kernel does require some of the latest features of the Rust compiler, the Beta version and the stable version will fail to compile under certain circumstances.

In addition to supporting AArch64, PowerPC and x86_64, ARM 32-bit and RISC-V are now also supported by this Rust for Linux.

Kotlin launches new logo

The official Kotlin blog announced the launch of the new Logo. The announcement stated that although Kotlin has been around for a long time, it has not been consistent in terms of visual style. The team hopes to create a brand logo for Kotlin that reflects a solid image, is iconic and highly recognizable, and is also diversified and easy to use.

However, when the team creates a new Logo for Kotlin, they also need to reconsider the previous design and maintain a certain continuity, so this makes the design process more complicated than it should be.

The updated Logo comparison is shown in the figure below.

Color is the most obvious place to change. The Kotlin team said that the color feel of the old Logo is outdated, and its overall impression does not match the modernity and evolving characteristics of Kotlin. In addition, although the stripes in the old logo help to highlight Kotlin and are recognizable, it is not a very unique appearance, so the team also decided to delete it. Remove the stripes and merge the colors of the old logo to form a new color with a gradual effect to make it brighter and more vivid. This is the characteristic of the new logo.

For the font, I chose JetBrains' own JetBrains Sans font, which makes people feel lighter visually. There is one more detail in the font. The "i" in the new Logo is specially designed to distinguish it from the "l".

The brand logo is a multifunctional tool that can be used in various scenarios. The Kotlin team chose 3D shapes as the basis of Kotlin's visual language because they can be used in many ways. These 3D shapes can be used as shapes, photo masks, icons, etc.
