Why don't they test the nerds at Shenzhen? These people might even beat Beijing and Shanghai there.
I'm not sure Shenzhen, Beijing, or Shanghai is the top performing city in China's own national college entrance exam (Gaokao). I'm not sure Jiangsu and Zhejiang are the best performing provinces in China's Gaokao either. There might be better performing cities and provinces in China than those. On the other hand, I think one of the most important reasons that B-S-J-Z were chosen to participate in the 2018 PISA was because these regions matched the conditions of the core OECD nations best in terms of income and development, more so than other poorer regions of China.

Huawei breaks free from Trump's tech trap
Far from being hobbled, the Chinese company is winning with 5G

HONG KONG -- When Huawei Technologies was blacklisted by the U.S. earlier this year, its founder rolled out the war metaphors. Ren Zhengfei spoke of a "life or death crisis" and handed journalists photographs of a strafed World War II plane, explaining that Huawei had been similarly targeted by Washington.

Seven months later, the world's largest telecom equipment company appears barely hampered by U.S. sanctions against it. In this, it represents a microcosm of the wider tech war: America's bark is proving much worse than its bite.

The addition of Huawei and 70 affiliates to the U.S. "entity list" in May was intended to prevent the group from buying parts and components from U.S. companies without government approval. The move was widely expected to hobble the Chinese company; its reliance on American suppliers would prevent it from making some of its main products, analysts said.

But reality has turned out differently. Far from being hobbled, Huawei has prospered in the intervening months. It raised its global smartphone market share in the third quarter of this year -- partly because of strong domestic sales swelled by patriotic Chinese buyers -- while rival Apple suffered a setback. Its revenues in the first nine months of the year grew 24% year on year.

Of greater strategic importance has been Huawei's success in signing contracts with carriers around the world to install equipment for superfast 5G services that are expected to make the "internet of things" a daily reality. So far, the company has sealed 65 contracts, with almost half coming from European countries -- despite U.S. diplomatic efforts to persuade allies to shun its technology.

In the case of the U.K., executives said Huawei has signed 5G contracts with four domestic carriers. This has occurred even though London has yet to decide officially whether to allow Huawei into the British 5G infrastructure network. One U.K. carrier, EE, which uses Huawei equipment, says it has already switched on 5G in 14 cities across the country.

As Huawei gains ground abroad, it has been scaling back reliance on U.S. suppliers wherever possible. A teardown of its Mate 30 Pro -- its new 5G phone -- reveals a mere sprinkling of U.S. components. There are a couple of items from Texas Instruments, a noise amplifier from Cirrus and a module from Qualcomm.

Japanese and South Korean components have pushed out U.S. suppliers in other areas of the phone, while high-tech parts made by HiSilicon, which is owned by Huawei, have seen their representation surge in comparison with earlier models.

Indeed, the dawning 5G era is shaping up to be a humiliation for USA Inc. Not only is Huawei also swapping out U.S.-made parts from its 5G base stations, but an accelerated build out of network infrastructure in some parts of China is likely to mean that the country leads the world in popularization of the new standard. With Apple not due to launch its first 5G phone until sometime next year, Huawei looks set to enjoy early mover advantages.

The same dash for self-reliance is seen in other key fields such as chipmaking. Yangtze Memory Technologies, a new Chinese company that makes NAND flash memory chips, expects to triple production to 60,000 wafers a month from next year at its new $24 billion plant in Wuhan, according to

.

In another example of the same trend, ChangXin Memory Technologies expects to quadruple production of DRAM chips to 40,000 wafers a month at its $8 billion facility in Hefei. The reason for the sharp increase in production plans is that chip customers are finding their quality sufficient relative to South Korean competitors, analysts said.

Overall, the U.S. tech war with China has fallen short of the intensity implied by Ren's military metaphors. Instead, Washington's actions are strengthening Huawei and redoubling China's broader insistence on self-reliance in crucial parts of the supply chain. This moment in history will become known as the time that China broke free.

Now, I read the following news from a Chinese website.

工信部批准中国信通院设立域名根服务器
Please, Log in or Register to view URLs content!


The Chinese domain name system (DNS) root servers are IPv6-based, while the US DNS root servers are IPv4-based. China has set up 25 IPv6 root servers globally since 2016. The Chinese DNS root servers are located in 16 countries. The Chinese DNS system is completely compatible with the US DNS system, but the US system is not completely compatible with the Chinese system. Now the world Internet is served by 25 Chinese DNS IPv6 root servers, together with 14 US DNS IPv4 root servers.


China is now ready for a US-initiated Internet de-couple. The biggest question now is: Is the US ready for it? Will the US upgrade its IPv4 system to IPv6? Money! Money! Money! Who is going to pay for the upgrade?

The following is its English version.

BEIJING, Dec. 7 (Xinhua) -- China's Ministry of Industry and Information Technology (MIIT) has approved the establishment of a domain name system (DNS) root server by a research institute Friday.

The China Academy of Information and Communications Technology (CAICT) has been permitted to set up a root server and a corresponding operating organization, the MIIT said, requiring that the academy observe relevant laws and regulations and be subject to supervision and inspection.

DNS translates easily-remembered domain names to numerical IP addresses, which can be recognized and processed through the Internet. It facilitates the use of the Internet by locating and identifying online resources.

As one of the most important infrastructure, root servers are essential to the Internet and concern Internet operations and information security.

While ensuring the stable operation of the server and providing quality service to users, the CAICT should also protect users' information security and safeguard national interests, the MIIT said.

later got curious, read both articles;

the data:



the fit:

(note on this very special occasion I don't say what values on the ordinate represent :-(


residuals of the fit (of course rounded to nearest, ehm, integer):
-34

-66
-193
145

make whatever conclusion you will

The US intention is dominance by threatening "de-couple others", that is to have the sole ipv4 Master Root Server in US control.
However, I don't think in case of ipv6, anyone has the chance to decouple anyone. So there is no such question "is the US ready for it" because nobody ever had a chance to solely owns ipv6 master root server from day one.

Ipv4 started as a US defense department project, later was handed over to civilian control but never outside US. It owns Ipv4, so the possibility to de-couple anybody. Ipv6 on the other hand was NEVER a US project, so there was never a chance.

See the ipv6 root server's location from the guancha article.


There are three Master root servers, with one in China, US and Japan respectively. There are many Slave root servers in many other countries. The master servers are on equal footing, meaning they sync with one another, keeping records identical. The slave servers will READ from masters. Hypothetically if US want to cut China out of internet as in ipv4, it will cause itself out of sync with not only China but also Japan. The slave servers will have to choose which master's record to trust. If the DNS specification use a voting algorithm to deal such situation, all slave servers will choose to read the Chinese and Japanese servers, effectively US blocks itself out of the world. This does make the ipv6 world democratic while ipv4 was dictatorial.

In the future, there could be more master root servers built in other countries, I am sure at least EU will build one in the near future. This distribution of master servers makes de-coupling others self-destructive.
