Cover: December 13, National Memorial Day for the victims of Nanjing Massacre


Recently, while having lunch in the canteen, I heard CCTV news 30 minutes broadcast the news that “the United States will launch a 301 investigation into the collection of digital tax in France”. Digital tax will be levied on Internet enterprises with an annual business income of more than 750 million euros or an annual business income of more than 25 million euros in France. The tax rate is 3%.

First of all, I think it’s incredible: does the digital world have to pay taxes? Pointing to the news and talking with Sabrina with a smile, maybe in the future, we will pay taxes when we buy stewed chicken with mobile phones. Sabrina rolled her eyes at me and asked, “don’t you pay tax now? The drumsticks in my hand are not fragrant all of a sudden.

Yes, everything in our lives, from cars and airplanes to soybeans and rice. Most of them are imported, there are taxes, and they are affected by trade.

According to the import and export volume and growth of all countries in the world in 2018 announced by the WTO this year:

ranking Imports (trillion) Export (trillion) Total amount (trillion)
first USA (2.614) China (2.487) China (4.632)
second China (2.136) USA (1.664) USA (4.278)
third Germany (1.286) Germany (1.561) Germany (2.847)

Ranking table of world import and export volume in 2018 (top three)

Compared with the United States, China’s import gap is only 0.478 trillion, while the export gap is 0.823 trillion. It’s almost twice as much as imports. This not only shows that China is becoming more and more powerful, but also shows that great changes have taken place in the world trade system. It is not difficult to understand why global populism is rising and trade protectionism is rampant. Because there are many people in the world who want to get off the bus. They are not enjoying the benefits of globalization. For example: Auto Workers in Detroit.

This time, France’s collection of digital service tax on Internet companies deserves the attention of every Internet user and even netizen. It’s very simple. In the past, most trade wars were based on the collection of tariffs in the form of goods. Now, not only France but also the European Union are studying, promulgating and formulating relevant laws in the field of Internet and digital. For companies that provide Internet services in their territory or for citizens of European Union countries, they will collect digital taxes, more stringent user data inspection, and protect user privacy, Trade wars have invaded the virtual digital world.

For Internet users, to develop an application in the future is not only experience and demand, but also security and privacy will become indispensable and even very important considerations.

For companies, it may be necessary to add some new posts such as application security or privacy product manager, and pay more attention to the policies and regulations of various countries for Internet companies.

For users, the free internet service may be far less than the charged Internet service, with better experience, more security and more attention to data privacy. And some services, will not be free to experience.

2.7 billion e-mail data leaked, including the e-mails of many domestic large factories

Wei'an weekly: Issue 2 (December 13, 2019)

I think data leakage is nothing new. Almost every year, big factories are exposed to leak data. But why put it in the trend? Because, the way of data leakage and the consequences that should be borne have changed greatly. In the past, most of the data was obtained by hackers pulling, hitting and hacking into the server. Now, the Internet is full of open access, or weak password database. Students who have a little snack and can use some related tools can freely obtain private data on the Internet. I don’t know how many tools are available on GitHub to scan GitHub, gitee and other open source project management websites.

Our company once had such a thing, interns package and upload the company code to their GitHub, and the code contains a lot of sensitive cloud service configuration information. Finally, it was swept out by the cloud service provider, and sent a major accident email to the boss of the operation and maintenance department late at night. That night, everyone was called again. As for how to deal with interns, I haven’t seen him next week. Later, listening to the interns of the same period, the boy went back to his hometown.

Therefore, in the era of cloud computing, most of the application services are almost on the cloud, and most of the cloud manufacturers will provide one click security tools, as well as very timely updates to repair various vulnerabilities. The probability of the server being broken is much lower than that of the company’s own server maintenance. Therefore, data leakage is mostly caused by improper operation. For example: for the convenience of debugging, open the database access rights of cloud service providers to any IP and any user.

Accordingly, improper operation leads to data leakage. In the past, the company may make an apology and fire the relevant personnel at most, but now with the improvement of the national laws and regulations on information security and personal privacy. The leakage of major personal privacy data caused by operational errors may also lead to the civil and criminal liabilities of the company and individuals.

From another point of view, data for a company is assets, and data leakage, in a sense, is the outflow of company assets. And it may have an unpredictable impact on the business.

Therefore, the focus on data and privacy security must be a trend in the future. Of course, the future is not yet coming. As individual users, how can we protect our data as much as possible? Please click

Breakthrough in graphene research! Discovery of magic angle superconducting switch

This research may completely solve the problem of chip heating, so as to greatly improve the performance of the chip. On October 30, 2019, Nature magazine published a joint study on graphene materials by Chinese, American and Japanese scientists. When there is a special angle of 1.1 degree between the two layers of single atom graphene, superconducting and insulating regions will appear alternately between the two graphene layers. More importantly, through a voltage change, we can control the opening and closing of the superconducting phenomenon.

If we master this technology, we can use it as a new chip principle to form a logic switch array by changing the voltage.

At that time, a chip without heat dissipation problem will be so attractive.

Survival Guide for software engineers

Wei'an weekly: Issue 2 (December 13, 2019)

I found that the more Internet engineers who have worked in a company for a long time, the better their knowledge structure, behavior, cognitive mentality and technical skills. They are gradually moving closer to the company, becoming more and more solidified, as if everything is adapting to the needs of the company and the colleagues around.

However, in modern society, there is rarely a company that can let you go from just leaving university and working to your grandson just leaving university. Even if you use it, the chance of you meeting it is very low. Therefore, I think, as an adult, if you want to live a stable life, first of all, you have to find out what the “hidden rules” of your occupation are. Then we talk about transformation, and then we talk about interdisciplinary collaboration.

Female programmer report in 2019: most people master C, Java and C + +

Female programmers are the apple of every company’s eye. When I read this article, my first thought is to recommend it to those new people so that they can give priority to these kinds of programming languages when they choose programming languages. Maybe it’s much better to find a female ticket than those who turn their eyes when they go to the base.

Summary for safety

In the future, careful readers may find that the technology module is only available in the first issue, but not in the next 1000 issues. Because for an, I have no time to make the second issue of Wei’an weekly. The technical module is about to open the window, so I cut it off. Ha ha ha. In fact, this week, I have been thinking about the core vision for an weekly. That is: a weekly that provides cognitive services beyond technology for technical people.

So why keep open source project modules? Isn’t open source project technology? Wei An believes that although open source projects are also technologies, they are not only technologies. Open source projects are more “works” of global technicians working together, exchanging and learning from each other. Although it can also increase the technical ability, it can not be ignored in terms of broadening horizons and communication. Therefore, keep the open source project module.
