Microsoft will release a new version of Windows on June 24, and it may be available in the fall

Microsoft said that the new software will include design changes, provide opportunities for creators and developers through the Windows App Store, and make it easier for users to connect with the communities they care about. After the conference, the software will be launched for so-called Windows Insiders who have signed up for testing, and may be widely released this fall.

Except for Huawei, no other mobile phone manufacturers have explicitly stated to use Hongmeng HarmonyOS 2

A very important reason why Hongmeng operating system is widely concerned by the market is its application on mobile phones. However, as of now, no mobile phone manufacturer other than Huawei has made it clear that it will carry the Hongmeng system on its mobile phone products. The industry believes that the ecological construction is still not perfect, which may be one of the reasons why many mobile phone manufacturers have not yet selected the Hongmeng operating system. Compared with some home appliances, mobile phones are used much more frequently and carry more user information. Mobile phone manufacturers have higher requirements for operating system stability and security. Compared with mobile phones, Hongmeng operating system has been applied earlier in the home appliances and other industries.

listing of 160c1955358da6 was terminated, it is rumored that JD Digital will lay off 30% of its

Recently, an employee broke the news on the platform that JD Digital has laid off 30% of its staff, which is said to be affected by the termination of the business line due to the listing. JD employees revealed that "Asset Management Technology has optimized 40 employees."

It is worth noting that on April 2nd, the #上海Stock Exchange’s termination of Jingdong Digital Technology’s listing review# The Science and Technology Innovation Board Listing Committee terminated the application for listing on the Science and Technology Innovation Board of JD Digital Technology Holdings Co., Ltd. because the issuer withdrew the application for issuance and listing or the sponsor withdrew the sponsorship .

US Space Agency announced that it will perform two missions to explore Venus

On June 3, the National Aeronautics and Space Administration (NASA) announced on June 2 local time that it plans to perform two new missions to explore Venus between 2028 and 2030 to study the atmospheric and geological characteristics of Venus. The project will receive approximately US$500 million in funding. NASA stated that these two missions are called "DAVINCI+" and "VERITAS" respectively. The contents include studying the evolution of Venus, further understanding the geological history of Venus, and analyzing the difference between it and the earth in the direction of development.

Google intends to strengthen the privacy protection of Android users and compete with Apple

According to news on June 3, Google is strengthening the privacy protection of Android users. These users hope that when they switch between different applications, it will be more difficult for advertisers to track them. Google is trying to compete with Apple, which has already taken similar measures, and establish a better image in managing personal data.

On Wednesday, local time in the United States, Google wrote to its app store developers and announced new policy changes. The company wrote in an email: "We want to provide users with more control over their own data and help strengthen security and privacy protection." Google added that after this reform, it tried to obtain those who chose not to be tracked. The developer of the Advertising ID for Android users "will receive a string of multiple zeros instead of an identifier".

Google plans to implement these new policies later this year, and experts say Google’s move is an attempt to contend with Apple. Last month, Apple enhanced its privacy protection capabilities by turning off the default tracking function and allowing users to choose whether to accept tracking as needed.

This reform will mean that billions of Android users can opt out of "interest-based advertising", gain more control over their personal data, and cut off the connection between advertisers and the massive amounts of data they rely on.

OPPO responds without Hongmeng: Support domestic innovation

According to OPPO, OPPO expressed support for domestic innovation and called for the joint development of the industry. “We pay close attention to industry-leading technologies and are committed to bringing users a high-quality experience.” Previously, OPPO’s public relations staff stated that OPPO does not use Hongmeng, and expressed their gratitude to Hongmeng. The system was denigrated. Later, the employee publicly apologized and resigned from OPPO.

New progress in Baidu's car manufacturing: priced at more than 200,000 yuan, a new round of financing

Jidu Automobile, a joint venture between Baidu and Geely, held a Q2 communication meeting in 2021. Jidu Automobile CEO Xia Yiping said that the first car of Jidu Automobile will be unveiled at the 2022 Beijing Auto Show. He said that the model that Jidu Automobile will unveil at that time is a concept production car, and the appearance is about 90% similar to that of a production car. If you are optimistic, you can make reservations within the next year. Previously, Jidu Automobile had stated that it would invest 50 billion yuan in the next five years for overall research and development and the continuous construction of a series of Jidu Automobile models. According to Xia Yiping, a new round of financing is planned in the third or fourth quarter of this year.

Apple is restarting the Apple Car manufacturing plan, the ultimate goal is to build a complete car

According to news on June 1, as early as 2015, Apple's internally called "Project Titan" (Project Titan) electric automatic car project began to surface. However, in the past few years, the strategic goals of the project have been repeated many times, and the technological progress does not seem to be great. Now, Apple is restarting its car-making plan, and its ultimate goal is to develop a complete car.

Around 2015, Apple aggressively recruited talents in the automotive industry, with more than 5,000 R&D personnel alone. But it never released the exact product, and later even narrowed the scope of its target, that is, it only develops autonomous driving software and sells it to third parties.

It was reported not long ago that Hyundai Motor Group of South Korea contacted Apple to discuss possible manufacturing partnerships, but the negotiations ended in failure. This incident not only confirmed that Apple is still advancing its car projects, but also highlighted another key point, that is, Apple CEO Tim Cook is unwilling to fall into Elon Musk’s Tesla. Increasing the production hell of Model 3 is obviously full of challenges in making cars. To this end, Apple under the leadership of Cook hopes to outsource production.

iPad mini 6 Preview: cancel the Home button performance and appearance upgrade

According to domestic media reports, Apple will release the new iPad mini before the end of this year. According to the news, the new iPad mini will use a narrower frame design, and will cancel the Home button to achieve a true full screen.

If this year's new iPad mini cancels the Home button, then this will be a major change in the appearance design of this series of products in recent years.

Apple's previous generation iPad mini was released in March 2019. This product uses a 7.9-inch retina display, equipped with an A12 processor, and upgraded memory to 3GB.

Earlier this year, it was revealed that the new iPad mini 6 this year will use an 8.4-inch display. The unlocking method will use Face ID or side fingerprint unlocking. It will be equipped with an A14 or M1 processor, support 5G networks, and provide 64GB, 128GB and 256GB. A storage version that supports Apple Pencil 2 stylus, etc.

It should be noted that this year's new iPad mini 6 will be upgraded in terms of screen, appearance and processor, and as the cost increases, it means that the price of this product will also increase further.

However, Apple's iPad mini products have always been positioned as entry-level products, so I believe that the price increase of this product should be within the range that everyone can accept.

Raspberry Pi sold separately RP2040 chip for only $1

Earlier this year, the Raspberry Pi Foundation (Raspberry Pi Foundation) announced the launch of the Raspberry Pi Pico microcontroller equipped with RP2040 for embedded development, priced at only $4. Today, the Raspberry Pi Foundation has decided to sell the RP2040 chip separately, which can be purchased through distributors for $1, for geeks or companies who want to build their own electronic products with this Raspberry Pi chip.

The RP2040 chip, which sells for only $1, has two 133MHz ARM Cortex-M0+ cores and can run software such as FreeRTOS and MicroPython. In addition to these two embedded cores, there are 264KB of memory and support for all common I/O interfaces.

The Raspberry Pi Foundation stated that the Raspberry Pi Pico development board has shipped more than 600,000 units this year, and there are more than 700,000 orders in addition to this. At the same time, more creators and companies have been seeking to use the RP2040 chip to build their own products, which is why they have decided to provide the chip now at a price of $1. The Raspberry Pi Foundation expects that the RP2040 chip will be on the market on a large scale this fall.

only small bangs, iPhone 13 final rendering exposure

Recently, the well-known whistleblower @Ian Zelbo brought us a rendering of the design of the final version of the iPhone 13 basic version (probably a mass production version).

Which not only further confirmed the appearance design of the machine, but also brought a new color scheme, which is a new color system similar to "brass color".

As for the details of the design, this rendering is basically the same as the previous revelations. The overall design still inherits the iPhone 12 series. The middle frame of the fuselage is still set at a right angle, but the front screen ushered in the biggest change in 4 years. Brand new little bangs scheme.

According to reports, Apple introduced a "hidden" handset solution, which moved the handset to the top of the screen to free up more space for the Face ID component, thereby reducing the area of ​​the bangs and the “obtrusive” on the top of the screen. There is a visible reduction in the area.

Thanks to this, the space left for the Face ID component in the bangs area of ​​the iPhone 13 series is effectively increased, and the area of ​​the bangs area is naturally reduced, and at the same time, it can also guarantee a very high security level of facial recognition.

As for the changes in the back, it is in the details of the camera. Among them, the dual-camera arrangement of the iPhone 13 series has been completely changed from the vertical arrangement to the diagonal arrangement. Although it does not seem to be in harmony, it seems to be more aligned with the three-camera arrangement of the Pro version. Unanimous.

Earlier, some foreign netizens exposed the "Rose Pink" color scheme, and the whole body adopts pink color scheme, which will have a great impact on the female market.

independent developer implements the Fuchsia OS simulator

The independent developer of Dahlia OS has implemented a portable Fuchsia emulator Flmage to help experience Fuchsia OS.

Earlier this week, Google officially released Fuchsia OS, but now only some users of the first-generation Nest Hub can experience it. Although Fuchsia OS is open source, users can download the code and compile it on their own computer, but it can still only run on compatible devices such as Google Pixelbook. Therefore, the developers of Dahlia OS implemented a Fuchisa emulator to help experience Fuchsia OS. The simulator already includes a pre-built version of Fuchsia.

However, the emulator only supports the Linux platform (the developer recommends Ubuntu 20.04 or above). If you want to get a good performance experience, a computer running Flmage needs more than 8 GB of memory, an Intel CPU manufactured after 2010, a fourth-generation Intel processor, and the latest graphics driver. If the computer meets the specifications, basically only need to download the latest Flmage version, unzip it, and then run a few terminal commands, users can start to experience Fuchsia OS.

In addition, the developers of Dahlia OS stated that they plan to update the FImage project to the latest version of Fuchsia on a regular basis to help fans of Fuchsia OS.

latest technology trends

GCC Rust continues to advance its upstream plan

According to the mailing list, the developers of GCC Rust are establishing a separate GCC Git branch and mailing list to continue to promote the upstream of GCC Rust.

The official Rust compiler implementation is based on LLVM, and the goal of GCC Rust is to become a complete replacement for the official Rust compiler. The project was founded in Rust 0.9 version, but Rust was not stable at the time, so the community development progress was not good. Unlike LLVM, since this is a front-end project, the compiler will gain full access to all GCC internal mid-end optimization channels. For example, users of this compiler can use the familiar -O2 flag to adjust GCC's Optimizer.

At present, the project is still in its early stages and has not yet been fully implemented. However, the developers of the GCC Rust front-end are trying to establish an official GCC Git branch to develop the project and establish a separate GCC mailing list to handle patch submissions and reviews to supplement their GitHub workflow. At the same time, their original GitHub repository will continue to exist. Through these efforts, they hope that the project can finally achieve upstream.

If you are interested in the progress of GCC Rust development, you can check its weekly status report. Recent reports show that the project has reached a generic milestone and is preparing to implement pattern matching and import related.

The successor of Windows 10 will bring improvements in processor scheduling to better support the new architecture

At present, we know very little about the unannounced Windows 11 or Windows "Sun Valley". It is said that it has a new start menu, action center, task bar, and other core components of the visual transformation, such as animation effects, context menus, application menus Wait. The latest news coming out today is that in addition to user interface changes, the next generation of Windows will also be equipped with large-scale scheduling updates.

Windows is equipped with a system scheduler, which is mainly used to determine the thread that should get the next processor time slice, control multitasking, and improve the overall performance of the platform. The scheduler is designed to use the scheduling priority to determine the next thread that should run, but currently it is not properly optimized for mixed CPUs.

According to reports, the upcoming Windows version will have a "mass scheduling update" to support Intel's upcoming CPU.

This is a statement from YouTube broadcaster Moore's Law is Dead. He also claimed that Intel's long-awaited 12th-generation lineup "Alder Lake chip" will be launched in October together with Microsoft's next-generation Windows.

According to reports, Intel’s Alder Lake chip will introduce a new motherboard socket, which will use both ordinary CPU cores and high-efficiency/low-power cores to provide notebook computers with better performance and longer battery life. Some reports claim that Alder Lake CPUs will provide significant performance upgrades over Rocket Lake.

Microsoft is obviously working with Intel to optimize the performance of the "Alder Lake-S" desktop processor. According to reports, Windows will get an improved scheduler to support this hybrid processor (CPU cores designed for different tasks).

The operating system will be announced on June 24, but will not be available to mainstream audiences in the production channel until the fourth quarter of 2021.

Computex 2021: ASRock releases Mars 5000U series mini PC

Although only 0.7 liters of volume, but in order to keep the AMD Ryzen 5000U APU cool, ASRock also equipped the machine with a proprietary fan + radiator combination.

In addition, the motherboard provides a pair of DDR4-3200 SO-DIMM memory slots (up to 64GB), a PCIe 3.0 x4 M.2 / SATA M.2 slot, a 2.5-inch SATA hard disk slot, and Intel Wi-Fi 6 wireless Network card interface.

In terms of power supply, it uses a 65W / 19V power adapter similar to a notebook computer. In terms of I/O interface, it provides four USB 3.2 Gen 1 Type-A (two at the front and rear), one USB 3.2 Gen 1 Type-C (front) and two USB 2.0 (front) ports.

Mars 5000G also has a built-in 3-in-1 card reader (compatible with SD / SDHC / SDXC memory cards), and supports HDMI + VGA (D-Sub) video output.

In terms of network, in addition to Gigabit Ethernet (wired), the machine also has an Intel AX200 wireless network card (supports Wi-Fi and Bluetooth 5.0). For audio, it provides a 3.5mm headphone/microphone jack.

From the appearance point of view, the ASRock Mars 5000U series is very similar to the previous Mars 4000 series mini PCs. The biggest difference is that the new model supports the upcoming AMD Ryzen 5000U series APU based on the Zen 3 architecture.

As for the exact CPU SKU, price and launch date, it is currently unknown.

Fuchsia's Rust code accounts for over 50%

Google recently officially launched Fuchsia OS to the public, and the device that received Fuchsia 1.0 push was the first-generation Nest Hub.

Unlike operating systems such as Chrome OS and Android based on the Linux kernel, Fuchsia uses a brand new, self-developed Zircon microkernel, which is written in C++. The components of the kernel are written in programming languages ​​such as Go, Rust, Python, and C/C++. For example, the USB driver is written in C++, and the network stack is written in Rust.

In the discussion thread about Fuchsia, some developers stated that Fuchsia uses Rust extensively to write code. According to the overall code analysis of Fuchsia, Rust has the most lines of code.

The proportions of the main programming languages ​​are as follows (including JSON configuration code):

• Rust 22%,
• C++ 18%,
• C 4%,
• Go 2%,
• Python 1%,
• Dart 1%

If the JSON configuration is removed and then counted, the proportion of Fuchsia's Rust code has actually exceeded 50%.

According to the previously reported "Fuchsia Programming Language Strategy", terminal developers do not support the use of Rust. Terminal developers here refer to those who write software for Fuchsia outside of the Fuchsia Platform Source Tree. In addition to being used in the Zircon kernel, Rust is also approved for use in the entire Fuchsia Platform Source Tree.

Mozilla self-developed translation tool, Firefox finally gains native translation function

Mozilla's Firefox browser is one of the most well-known browsers in the world. Previously, the browser did not have its own translation tool. Users need to install extensions such as Google Translate to implement web page translation functions.

Project Bergamot is Mozilla's translation tool development project. Since the project was disclosed in October 2019, Mozilla has been developing this Firefox translation function. The first Firefox translation tool available to users was released as a browser extension last month. Earlier this month, the second version was also released, and the tool was officially named Firefox Translations.

The translation function of Firefox Translations is completed locally in the system. This is a completely different point between this translation tool and the current mainstream solutions on the market (for example, the Google Translate translation of the Chrome browser is completed in the cloud).

Recently, Mozilla officially announced that it has integrated this privacy-friendly translation tool into the latest version of Firefox Nightly. This function is not enabled by default, and the user needs to manually enable it. Firefox Translations only supports a few languages ​​such as English and Spanish for the time being, and Mozilla promises to support translations in more languages ​​in the future.

How to enable Firefox Translation

1. Load about:config in the Firefox address bar;
2. Search for extensions.translations.disabled;
3. Set this preference to FALSE to enable the translation function of Firefox;
4. Restart the browser;

Use built-in translation function

After enabling this feature, when a user visits a website in a supported language, Firefox will display a small translation bar at the top. This translation bar is very similar to the Google translation toolbar on the Chrome browser. The user can set whether to translate or not. The translation language and whether the future will be automatically translated.

Intel released two 11th-generation low-voltage CPUs: i7-1195G7 and i5-1155G7

At Computex2021 in Taipei, Intel released two new U-series low-voltage processors for ultrabooks. The models of these two processors are Core i7-1195G7, which is the higher performance product in the U series, and Intel Core i5 -1155G7, which is the mid-range model in the Core i5 series of chips.

Both of these new chips operate in a power range of 12W to 28W and have a four-core eight-thread configuration. They are also equipped with Intel Iris Xe integrated graphics-i7-1195G7 has 96 EUs, and i5-1155G7 has 80 EUs.

Although the basic frequency of Core i7-1195G7 is 2.9GHz, Intel's Turbo Boost Max3.0 technology is used to increase the maximum single-core speed to 5.0GHz. On the other hand, the basic frequency of i5-1155G7 is 2.5GHz, and the boost speed is 4.5GHz.

Compared with AMD Ryzen75800U CPU, i7-119G7CPU can provide 46-178% performance improvement in games, and its video editing speed has increased by 93%. Intel said that while running different applications and processes, it provides a significant performance upgrade over its competitors.

In addition to these new chips, Intel also announced the Intel 5G solution 5G 5000. This is an M.2 module that has passed global coverage certification, including operators AT&T and Spring that have certified the module. It is said that its download speed is as high as 4.7GB per second, and the upload speed is as high as 1.2GB per second, which is about five times faster than Intel's Gigabit LTE technology. The modem was developed in cooperation with MediaTek and Fibocom and will be used in more than 30 notebook computers by 2022.
