The Sony IMX820 full-frame sensor uses CoW packaging technology, which can reduce silicon waste, improve yield and reduce costs compared to traditional WoW solutions. This technology may also be applied to Sony’s exclusive 33-megapixel sensor
Preface: The purpose of this article is to help friends who are interested in Mac OS and cannot use Mac devices for some reasons install Mac OS in a commonly used system environment. Since I am also a novice and my level is quite limited, there may be some operations in the article that are unreasonable or incorrect. Some functions of the system I am using now are also abnormal. Old birds, please take a detour.
Friendly reminder 1: This sharing is only applicable to computer motherboards that support uefi. If the motherboard does not support it, this method is not suitable for installation.
Friendly reminder 2: Since the two systems in this article are installed on the same hard disk, the system efi partition needs to be larger than 400m. If there is insufficient space, subsequent installation will not be possible. Please ignore this prompt if installing on a different hard drive.
Friendly tip 3: If you are a reader who knows little about the operating system, you can do some popular science first, and at least you can install Windows independently.
Friendly reminder 4: This article uses a desktop computer as an installation example. The approximate configuration is i7 2600k + asus p8z77 pro + GV-N960G1 + samsung 4gx4. Computers with different configurations will also show differences during the installation process, so the following installation process is for reference only.
Let’s get to the point
The raw materials required for this article: computer with Win installed x1, Mac OS X system image x1, Win PE image x1, USB disk x2, and several related software
Step 1: Copy various images into the USB disk
Run Floppy Drive on a Win system computer, select the Win PE image, and set the writing device to USB disk 1 for later use;
Run transmac, format U disk 2, select the Mac image, and write it to U disk 2 for later use.
Step 2: Allocate Disk Space
Right-click the computer icon under Win system, select Management-Disk Management, select the compressed volume in the Win disk area, allocate appropriate disk space (40G+ recommended), and then follow the system prompts to complete the operation.
Step 3: Modify the boot configuration (Clover) file and add the driver
Friendly reminder: This installation uses Clover boot. Other boot methods (such as Chameleon) will have some differences in the configuration files. Clover writing can be completed by directly writing to the booted image (it can also be copied directly to a USB disk). Different versions of Clover may also cause some installation problems, so the examples in this article are for reference only.
Open USB disk 2, enter the directory *EFICLOVER and edit the config.plist file therein. Here is a reference example. This file generally cannot be copied directly and needs to be modified according to the computer hardware. Place some necessary driver files into the corresponding directory of the kext folder.
Step 4: Install Mac OS X
Restart the computer and select uefi mode to boot USB disk 2. Enter Clover to boot, select the fruit icon and press the space bar. During the first installation, select the boot Mac OS X with Injected Kexts option.
Important: After selection, you will enter the installation interface process. If problems such as system restart or system freeze occur during this period, please record the prompt text before the problem occurs (you can use Clover to record the log or take a photo), then use this prompt to find the cause and modify the config.plist, and perform this step again until you can enter the installation interface.
After entering the installation interface, open Disk Utility, select the allocated space, perform the wipe operation, and execute the installation program after completion.
After the progress bar runs out, the system automatically restarts. Select U disk 2 to start again. Enter Clover and select the newly appeared fruit icon. Still select the Boot Mac OS X with Injected Kexts option. After completing the configuration according to the prompts, you can enter the Mac desktop.
Step 5: Add startup items
After completing the first 4 steps, you can enter the system normally, but USB disk 2 is required as a boot every time you start. This step is to allow the system to disconnect from the USB disk and directly choose to start.
Restart the computer and select USB disk 1 to start. Execute cmd-diskpart to add the efi partition number
Copy the Clover folder in USB disk 2 to the newly added efi partition, and then restart the computer.
Enter the Win system and use easyuefi to add Clover boot and put it at the top of the startup items (refer to the picture below to modify).
If you do this, it will directly enter Clover boot every time you turn on the computer instead of booting to Win. In Clover, you can choose to enter Win or Mac OS. If you need to enter Mac OS directly, you need to inject the kexts in step 3 into Mac OS or modify config.plist, which can solve the problem of needing to select Boot Mac OS X with Injected Kexts every time you enter the system.
After completing the above five steps, Black Apple can only be regarded as a relatively preliminary stage. There are still many imperfections, such as no sound, suspended animation and other problems, and some problems are still unsolved until now. If you want to make it as perfect as possible, you need to post more and work harder. I hope this article will be helpful to those who are interested.

It currently supports more than 90 service tags such as fresh air, large trunk, and smooth driving, covering more complex travel scenarios such as supporting the elderly and the young, and business receptions.
IT Home attaches the official detailed introduction as follows:
You can say directly to Xiaodi (voice/text is acceptable):
You only need to express your needs or status naturally, and XiaoDi will translate it into labels that the platform can execute. For example, if it recognizes "physical discomfort" and "motion sickness", it will activate labels such as "driving smoothly" and "fuel truck".
If there is no perfect match at the moment, Xiaodi can also prioritize complex needs: meet your core needs first, and pragmatically provide the current "better solution".
When a multi-person trip has multiple passing points, Xiaodi can also complete the pick-up route planning; after entering the "home" and "work" addresses once, you only need to say "go home" or "go to work" to automatically match the destination.
Xiaodi can also do some handy things, such as:
Ask it "Which coffee shop is nearby?" and it can directly call a car for you with one click.
When traveling long distances, let it recommend you transfer options among multiple modes of transportation.
You can also leave it to it to check orders, book rides, etc. with "Fancy"
With AI Xiaodi, your travel will be greatly upgraded; customized travel can be customized in one sentence, various complex scenarios can be easily handled, and all nearby outings can be clearly arranged!
Now, we invite you to be XiaoDi’s “Experience Officer”: upgrade the Didi Travel App to the latest version, and click “AI Car Hailing” on the homepage to experience it.

v1.0 is just the beginning.
You can tell Xiaodi what AI taxi-hailing capabilities you want at any time - your imagination may be the function of its next version.
Prepare for a construction boom in the country? The outside world has noticed that North Korea has recently significantly expanded the import of various types of machinery and equipment. According to a report by the South Korean media "Daily North Korea" on the 13th, which focuses on North Korea, North Korean trading companies have continued to import agricultural machinery, engineering equipment, industrial machinery, shipbuilding equipment, and medical equipment from the end of last year to the beginning of this month. Among them, agricultural machinery includes tractors, planters, etc., engineering equipment includes excavators, bulldozers, etc., and industrial machinery includes lathes, injection molding machines, etc. These equipment mainly come from China, and some are second-hand goods, entering North Korea through multiple border ports such as Dandong and Hunchun.
The media said that the import volume of machinery from North Korea has surged in the past three months, even triggering discussions among Chinese traders that "North Korea has never imported so much machinery." At the same time, passenger trains between China and North Korea have resumed operation after six years, and the trade atmosphere on the Dandong border has become active. Goods from North Korea are also sold at higher prices in the market.
Seeing this news, some people may wonder the most direct question: Where does the money come from when North Korea buys so many things? After checking some trade data in recent years, I found that it should not be a big problem. In recent years, a large-scale wig trade has emerged between China and North Korea. According to customs data analysis, wigs alone will bring a RMB trade surplus of approximately 100 million yuan to North Korea in 2025. Judging from the comparison of import and export data, not all of these finished wigs may be sold back to China, but a large part may be sold to Russia or other third-party markets.
In addition, since the Russia-Ukraine conflict, North Korea has obtained opaque but considerable strategic income by providing military supplies to Russia. This input of foreign exchange or equivalent supplies is the "first pot of gold" for North Korea to launch a series of domestic construction projects. Taken together, North Korea can afford to use these revenues to import machinery and equipment that are crucial to economic development.
With the machinery in place, the next question is: Do they have enough fuel or electricity to run? There seems to be no need to worry too much about this. According to Chinese customs data, China's refined oil exports to North Korea have significantly recovered and exceeded pre-epidemic levels after experiencing extreme shrinkage during the epidemic (only more than 5 million yuan a year).
Another key data is electricity. Since there is no internal data from North Korea, we can only observe it from the side. For hydropower stations cooperating on the China-North Korea border, the electricity sold by North Korea to China has increased from 276 million kilowatt hours worth about 79 million yuan in 2019 to 562 million kilowatt hours worth about 174 million yuan in 2025. The power transmission has doubled, which strongly implies that North Korea's domestic hydropower stations are likely to have completed technical transformation, quality improvement and expansion as a whole. In addition, with the completion of a series of new hydropower stations such as Pyongkang, Sepo, and Goseong in recent years, its own power generation capacity has been enhanced. Coupled with the energy support received from Russia, it can be inferred that whether it is oil-burning tractors, excavators, or electric machine tools, injection molding machines, these imported equipment are unlikely to be bought back as furnishings. They have corresponding energy guarantees for actual use.
From the list of imported equipment categories, we can clearly see the logical chain of North Korea's economic development. Agricultural machinery is responsible for improving the basic production capacity of food and raw materials; engineering machinery serves the construction of factories, residences, hospitals and other infrastructure across the country; various industrial machine tools and injection molding machines provide production tools for local industrial factories under the "Local Development 20×10 Policy"; even CNC cutting machines and welding machines in shipyards appear on the list, pointing to more advanced processing and manufacturing fields.
This is a complete map from basic to advanced, from raw materials to processing. As these devices enter the production cycle, the value chain created within North Korea will be extended and enhanced. Once the internal economic cycle is up and running, more products can be produced for domestic consumption and export, and people's lives will naturally become more comfortable.
Even if many of them are second-hand equipment, it is completely suitable for restarting and upgrading an industrial system that has been dormant for many years. And since China's economy has been in a period of adjustment in recent years, with more idle equipment, the price of some second-hand goods may be much more affordable than during the economic boom. This change is tangible and can be seen in the fact that residents of Dandong on the border between China and North Korea began to sell more and higher-priced North Korean goods. This year's scene is likely to be just the beginning of a big era.
Of course, looking at the long-term trend, this large-scale import boom of machinery and equipment may not necessarily continue forever. There are two reasons. First, machinery and equipment are durable goods, not fast-moving consumer goods. Once the procurement is in place, only consumables and repair parts need to be replenished over a long period of time, and frequent large-volume purchases will not be required. The second is that in order to save precious foreign exchange, North Korea will inevitably use its own industrial base and scientific research capabilities to accelerate the imitation and localization of low-end and mid-range equipment.
In fact, North Korea has always had its own tradition in reverse engineering and adaptive innovation. Its "Cholima" series tractors and "Fenghuo" construction machinery have Chinese origins. In the future, it may still have to import mid-to-high-end core equipment that it cannot manufacture itself, and if the industrial upgrade goes smoothly, it may even import more advanced and sophisticated equipment. The import structure will shift from "comprehensive distribution of goods" to "compensating for weak links and climbing high-end".
New trends emerging on the China-North Korea border—large-scale imports of production equipment rather than pure consumer goods, and the resumption of passenger trains bringing more frequent movement of people—are strong signals that what is happening within North Korea is a substantive change based on productivity improvements. It is not simply consuming foreign exchange to purchase the means of living, but investing in the means of production with the aim of expanding future reproduction.
The foundation of this change is much more solid than growth driven solely by consumption. With the further smoothing of logistics and people flow channels between China and North Korea, the speed of North Korea's economic recovery and construction is likely to continue to accelerate. In an industrial system that has been silent for a long time, after receiving external energy input, the sound of its gears restarting has become increasingly clear and audible.
This is also a question with no standard answer. Everyone’s learning potential, effort level, and acceptance ability are different. However, according to the rules of language learning and most examples, if you study in a peaceful English language atmosphere, it may take between 8 and 12 months. Moreover, just because you speak English fluently does not mean that the English you speak is accurate and standard, right? If you just speak fluently, but the English you speak is not correct, then how does it count? Generally speaking, the improvement of English proficiency will go through three stages. First, you are in the primary stage, just like you have zero foundation. At this time, your grammar and word order may not be perfect, but these are not important at this stage. The important thing is to make you dare to speak English. Even if you are jumping out one word after another, you must insist on speaking. Dare to speak. This is the most important step for English beginners. Then, the second step is how to gradually improve the fluency of English from babble. At this time, you can speak English sentences, or you still have problems with English grammar, but at least you can express your thinking relatively fluently. The third step is self-examination. At this time, your English fluency is no longer a problem, but you have to make sure that the English you speak does not have many major English grammar problems. Even if you say problematic sentences, you may correct yourself. The last step is how to make your spoken English more authentic and authentic. This is the most difficult part for us Chinese students. If you have not lived and studied abroad, there are very few people who have reached this step. Most people speak English with Chinese thinking. It can be seen that it is really not that easy to master English well. If there is no language environment and no teacher's help, then it may take you longer. Therefore, when learning English, you should not be too impatient. It requires long-term accumulation.

Xinhua News Agency, Washington, March 17. When meeting with visiting Irish Prime Minister Martin at the White House on the 17th, US President Trump once again expressed dissatisfaction with NATO allies for not participating in the escort operation planned to be launched by the United States in the Strait of Hormuz, saying that he was "disappointed" in NATO.
Trump told reporters that "NATO is making a very stupid mistake." "I wonder if NATO will support us. So it's a good test because we don't need them, but they should be there," he said. "The United States has to remember this because we think this is very shocking."
Trump claimed that the United States has invested "trillions of dollars" in NATO over the years, which is one of the reasons for the United States' fiscal deficit. However, in response to a question about whether to reconsider the relationship between the United States and NATO, he said "there are no plans at the moment."
Trump declared that it “won’t be long” before safe passage through the Strait of Hormuz is possible. He also said that the United States is not yet ready to end the conflict with Iran, but "we will leave in the near future."
The United States and Israel launched large-scale military operations against Iran on February 28, and Iran launched counterattacks against Israel and U.S. military bases in the Middle East. Affected by the war, shipping in the Strait of Hormuz was almost completely disrupted.
In recent days, Trump has continuously urged European countries and other allies to participate in escorting the Strait of Hormuz, and complained that some allies are "not enthusiastic" about assisting the United States. Earlier on the 17th, Trump posted on social media that most NATO "allies" had informed the United States that they were unwilling to participate in US-Israeli military operations against Iran, and that the United States "no longer needs or expects" the help of NATO countries.
EU High Representative for Foreign Affairs and Security Policy Karas stated on the 16th that this is "not a European war" and "no one wants to be actively involved in this war." EU member states have no intention of extending the current "Shield" escort operation in the Red Sea and Gulf to the Strait of Hormuz.
Everyone knows that most of the world's global organizations and institutions, including the United Nations and the Olympic Committee, use English as their main working language. International business activities also use English as a communication tool. Two countries that speak different languages have English as their common language. Nowadays, whether you are studying, working or traveling, you cannot do without the help of English language. So now, whether they are students in school or employees outside, there is a huge demand for learning English. Everyone wants to learn English well and add more security to their future. So, many students must have asked how long it takes to learn spoken English from scratch? Today, I don’t dare to answer any questions about how long it takes to learn spoken English from scratch.
1. How long does it take to learn spoken English from scratch?
For students with zero foundation, speaking is basically a brand new field. The length of time it takes varies depending on the purpose and needs of learning and the individual's ability to understand and accept knowledge.
But as long as you master the scientific method, it is not difficult to learn spoken English from scratch.
Pronunciation is very important. Only when you know how to pronounce and accurately understand the meaning of the word can you output it. When learning spoken English from scratch, you don’t have the concept of English pronunciation in your mind, so the first step is to do a lot of listening input. "Listen more and speak more" cannot be skipped.
2. Learning software suitable for zero-based use
1. Jili Guala: An APP that focuses on English enlightenment. It takes American English as the starting point and focuses on listening, speaking and natural spelling. There are vivid videos and animations in it, which are suitable for beginners and can attract attention. It is not a boring thing and can truly learn knowledge through playing.
2. Memory Treasure: Memory Treasure English APP has very rich expanded content, including both Chinese and English pronunciations. Other software only has English pronunciation and no Chinese pronunciation. Its functions are much more powerful than ordinary software. This APP can create your own word list and create the words you memorize.
3. Acaso Speaking Show: Acaso Speaking Show has a simple interface and features the ability to use wired controls to read along. Office workers can use it to practice listening during commuting. Using the method of picture memory, the included example sentences are read in an interesting and stimulating tone, and are very situational. Support real-person pronunciation to ask questions.
4. Seed: Seed features a simple page style and real-time updated news. You can learn a lot of practical words and understand some foreign news information. You can click on words you don’t know to view the definition and pronunciation. You can also add new words to the list for timely viewing and review.
5. BaiCiZhan: BaiCiZhan is a "Picture Memorizing Word Software". The software provides interesting pictures and examples for each word, making memorizing words a pleasure. One word and one picture, using graphics to establish the connection between the word and the real environment, to create the most memorable and memorable word memorizing software.
3. What books should I buy to learn English with zero basic knowledge?
New concept 1: Basics of phonetic grammar.
New concept 2: Four rounds of grammar review arrangement.
New concept 3: Each story is not only interesting, but also consolidates what has been learned in the two volumes from a syntactic level.
New concept 4: There is also a story about "Foreigners who went to study abroad were surprised that my foreign language was so native".
Not only can each volume be studied separately, but you can reach the corresponding level after studying it.
Adapt to the crowd:
Textbook: New Concept English Volume 1 is a stepping stone for learning English. (First Things First)
Suitable for people: learners who have zero starting point or poor English foundation and want to master the basics of English in a short period of time.
Textbook: New Concept English Volume 2 is the cornerstone of building English. (Practice and Progress)
Suitable for people: Students who have mastered the first volume of "New Concept English" but have weak grammar foundation and need to learn grammar systematically.
Textbook: New Concept English Volume 3 The Key to Mastering English. (Developing Skills)
Suitable for students: Students who have mastered the second volume of "New Concept English" and have certain English grammar, vocabulary and sentence structure.
Textbook: New Concept English Volume 4 Expanding English Vocabulary.
Suitable for the crowd: Students who have mastered the third volume of "New Concept English" and want to further improve their English reading ability.
4. How to improve spoken English
For students with zero foundation, speaking English requires more open-mouthed practice. Let me share with you the app I am using: Liuxiaoliu. You can have one-on-one oral practice with Native Speakers from all over the world at any time. There are many professional TOEFL foreign teachers to choose from, and there are also former senior TOEFL examiners. It is strongly recommended to take a mock test with a TOEFL examiner before the exam. Using this software is just like making a WeChat voice/video call, and the quality is very clear. This is the APP that surprised me the most and is extremely cost-effective.
After downloading and registering the Liuxiaoliu app, be sure to enter my recommendation code: ZXN0GT to get 10 minutes of practice time for free.
However, when you are practicing IELTS speaking with foreigners, I have two suggestions: 1. Prepare a topic in advance. Practicing with them with the topic can help you learn a lot of authentic expressions; 2. You don’t have to choose foreigners from Europe and the United States. Some South African and Filipino people are also very professional, and practicing speaking is also good.
We have carefully compiled the article "How Long Does It Take to Learn Spoken English with Zero Basics and Which Learning Software is Suitable for Zero Basics" for everyone. I don’t know if you are satisfied with it. If you want to know more information about language training, please pay attention to the language training column. Source of this article:
