After the end of the two-round series, AC Milan failed to go any further, but fell at the feet of its sworn enemy in the same city. As the defending champion, Milan’s performance has been stumbling this season. Although the Champions League has reached the semi-finals, the league competition for the fourth place is in jeopardy. A series of wrong operations last summer laid the foundation for this chaotic season. How to restart the Rossoneri revival requires Milan to think and choose together.

[The four-game losing streak has made the Milan summer window even more inefficient]

Even after 16 years in the semi-finals, Milan’s Champions League journey this season is quite bitter and embarrassing. In two rounds, I suffered a double kill from my rival Inter Milan in the same city. Counting the Super Cup and the second round of the league, I was defeated by my opponent four times in a row, losing 7 goals but not scoring 1 goal. No matter what ranking Milan will end up in this season, it is a fact that Milan’s four-game losing streak in the derby is absolutely zero, which makes the team miserable both inside and outside.

Losing the Champions League to a deadly enemy and competing for the fourth place is in jeopardy. For a defending champion, this is definitely an unacceptable result. Coach Pioli has almost overdrawn his prestige in this stumbling season. Although he helped Milan to return to the Champions League and win a Serie A championship, the successive fiasco in January has made him "stand in prison" in the hearts of many fans, and the four-game losing streak in the Derby is even more "solid".

The total score of 0-3 is not good-looking, and Pioli’s use of troops is also debatable. But in the last two weeks, Milan has already run out of ammunition and food. In the first round, Leo was injured and the midfielder Ben Nasser was damaged; In the second round, defender Jiafu went off halfway, and Kalulu, who came off the bench, made a big mistake carelessly. The rest of the players are almost drained by the long season, and Gill, Special Olympics and krunic have all shown fatigue; Mesias and Tonali struggled hard, but they were powerless.

The bigger gap between the two sides actually lies in the rotation of the lineup. On the starting Milan may be equal to Inter Milan, but in the long-distance running of the season, Milan’s replacement lineup seems to be weak. Last summer, five players, such as Decatur, Origgi, Adelie, Dester and Franks, who were introduced and returned, failed to meet expectations and were not even included in the Champions League registration list. Only German defender Jiafu and youth training teenager Pobega showed certain value.

From the appearance lineup in the Champions League stage, we can also see Milan’s inefficiency last summer-Decatur, who invested heavily, only played in the first leg against Tottenham in the knockout stage; The only new aid with a starting record in the knockout round is Zhongwei Jiafu; In the two wars against Naples, not even a new aid started. Milan lost Casey and romagnoli last summer, and Ibrahimovic was close to retiring, but the Rossoneri hardly got any new blood, and it was almost doomed that they gradually declined at the end of the season. Inzaghi can let Lu Kaku play the league, Zhe Ke play the Champions League, and Milan can only hope that Gill will stick to his teeth.

[The concept is different, but the operation is different]

Therefore, the gap between Milan and Inter Milan in this series is actually the gap between the summer window transfer results. In the past year, both teams have experienced brain drain, and Inter Milan chose to fill it with mature players, such as Lu Kaku, acerbi and mkhitaryan. However, Milan chose to invest in young players to "scratch the lottery". Except for Origgi, who signed for free, all the other players are young people under the age of 23.

Two different strategies have different advantages and disadvantages. Inter Milan’s choice can bring more instant fighting power to the team. The third-line parallel is closely related to the performances of mkhitaryan and Lu Kaku. acerbi’s aging and growing stronger offset the negative impact of skrinjar’s "defection", so that Inter Milan will not lose its fighting power because of the absence of the core central defender. However, the cost of the lineup is high and the age is high. Even if the Champions League income is more than 100 million euros this season, the Nerazzurri’s loss has reached 100 million euros.

In contrast, Milan pays more attention to the long-term growth of the lineup, but it also loses experience and ability. Apart from Gill and Kyar, there are no core players over 30 in Milan. The cost of the lineup is also relatively controllable. With the Champions League results this season and the breakthrough in sponsorship, the Rossoneri, which had suffered losses for years, are expected to have a financial balance or even a small profit this season. But investing in young players requires patience, and not every bet can be rewarded. Germany’s Zhongwei Jiafu performed well in the second half, but in the first half, he experienced several months of "slow fire"; Decatur, who has high hopes, has not adapted yet.

But on the other hand, the operation of Inter manager Mallota is still more sophisticated than that of Milan director Paolo Maldini. In recent years, Inter Milan has lost its lineup every year, but Mallota, a seasoned player, has played a perfect game. After Lu Kaku left, he signed Zhe Ke, while Eriksson signed Chaer Hanoglu when he suffered from heart problems. Instead, it was the teams of Rome and Milan who took most of the damage for Inter Milan. Even if Inter Milan’s financial problems are frequently reported in newspapers, Mallota can still guarantee the team’s basic set at the league level.

But Maldini’s operation was too idealistic last summer. Hong Niao Fund hopes to invest in young players, but it is free to choose the specific target. However, the Milan uniform team did not supplement the backcourt when Kathy and romagnoli left the team. Instead, they introduced an attacker with unclear characteristics and outstanding strength, Decatur. Every time Maignan is in a hurry, many Milan fans will think, how nice it is to spend this 32 million yuan on a lower back!

Start all over again, but who will get a second chance? 】

Outside the stadium, Milan also sent ominous signals more than once. Before the first leg of the Champions League, Maldini called Hong Niao Capital and asked for more investment. After the exit, he once again pointed the finger at the management, claiming that "the management’s strategy" decided the transfer operation. In fact, the relationship between local managers and investment funds in Milan has always been subtle. In 2020, even Bo Ban was fired after firing at the employers. This time Maldini chose to fire, which made people worry whether he would make the same mistake again.

Both Eliot and Hong Niao Capital are obviously profit-seeking, hoping that the value of the team will gradually increase. But on the other hand, Maldini received a lot of financial support. Last summer, Milan’s net investment was the first in Serie A, and 32 million euros of Decatur also set a new record in the American-funded era. While criticizing the management strategy, the resource allocation and choice of trader Maldini are equally worth examining. However, with the exit from the Champions League, the contradiction between the two sides seems to be open again. Before starting again, perhaps the Rossoneri will have to face internal friction first.

A wave of 1500 people were organized before the activities of Alibaba Cloud servers, and 200 people were organized. But I am not organized now.

But when organizing this activity, I learned that everyone has a common question:Is this server use? ?

When it comes to the server, many people may say distributed, do calculation, crawl, and procedure background service, multi-person cooperation, etc.

In fact, these ordinary people can not use it, I will say that everyone can use it.

Everyone must have a work folder when you work, the students are your own courseware, exam, prepare for interview, and so on.

The friend who has already worked, there will be a file that puts your own important document, MarkDown, Pictures, Resume, etc.

Such an important folder, and we have to update every day, and we are worried about the computer is lost, or it is broken, suddenly these are not seen.

So we want to back up.

There is also our frequent personal computers and working computers to synchronize some private information, rather than passing on WeChat.

These are the use scenarios of Git private service, and it is very easy to use.

Everyone also knows GitHub, Gitee can also engage in private warehouses to back up, synchronous files, but their documents may put a lot of important information, including their own passwords, key classes, and put it above. It is not necessarily safe. You are not afraid of which major bugs will leak your information [wit]

More crossed, GitHub and Gitee are speed-off. After all, the functional positioning of people is not a network disk.

There is a large file in the project (more than a few hundred m), such as PDF, PPT, etc. It will make you suffocate.

Later, I will send a document to tell, how do you have a git private service!

This can be used to generate a download link of the file, or the local file can also be transmitted to the server.

It is equivalent to making an object store, in fact, cloud manufacturers also have objects stored.

However, we can do one, not enough, very classmates, you should not know how object storage, in fact, we can use the server to be a similar company.

I have been deployed on the server with a tool written by Go now. Used to pass files with the server, or create a temporary download link for some files.

These are direct command lines,

In this way, I wrap the command package into a shell command, want to pass the file, directly uploadTomyServer, and then return to the downloadable link, this file also passed to my server.

I also put my project code on GitHub:

Interested exciting friends can go to learn a wave, and give a star. Haha.

Do a website, for example, everyone knows how to write a few lines of code with HTML, but how to show someone else?

If you use your own computer to do a server, you can only access your website with your device in the same router, and this device can not have your website.

Because your IP is not a public IP.

If there is a cloud server, it is a public network IP, your website can make anyone visit.

Or a service you provide allows anyone to use.

For example, in the second example, we can develop a file storage, this service, I only put the command line to others, others can use my service to generate a link, of course their files have passed to me. On the server.

Again a way of use.

I have previously organized the activities of the server, Ali Cloud gave me an Excel, let the face are the list of friends who buy servers here, I will directly put this list directly to the group, let everyone check, appear in list You can find me to cash back, do you have anything.

There are several big problems that do this:

• Everyone is going to download Excel, do contrast, there will be someone to change the content of Excel and then say it is bought from you, I can’t make a comparison with Excel.
• Excel has a personal information from others, which is unstoppable.
• If everyone uses Excel inquiry, private letter I cash back, one is nearly two thousand people to find me cash back, my WeChat is imposed, this becomes physical activity.

How should I do it?

I simply write a query page, the backend logic is to read an Execl form, everyone enters her Ali Cloud ID in the query page, if in Excel, the page will return the QR code of the cash back group, everyone can be independent Scan code is plus group.

In this way, I will finally send an equal red envelope directly in the cash group, is it great to reduce human cost?

Of course, I generated the QR code of 17 cash back groups. According to certain rules, they show friends passing through the query.

It is such a very ordinary query page.

After the query passes, the cash back group is displayed.

But to deploy on the server, because there is no public network IP, others can’t use your service.

Learn Linux

Learning Linux actually engaged in a virtual machine on your computer, or you can also learn the dual system, but this is very testing how your computer performance is.

If you have a server, it is a separate computer. How do you Hoho Huoho, and you don’t have to shut down a year, you can always run your task, and your local computer is completely isolated.

More convenient, you are now in the system, such as Centos, want to do an experiment, need to be on the unbantu, if it is a cloud server, the replacement system is in the background point, one button is reloaded, the cloud manufacturer basically supports all the system installation of.

We usually play Linux is often equipped with various environments, then this Linux is played by yourself (generally unwarring use root permission), in short, the environment is unable to reload, basically reload.

The cloud server reloading the system is too convenient.

There is also an environment where you are not easy to match. If you play this environment later, you will go back to this previously matching environment rather than re-fitting the system.

Then you can save the function with the cloud server, you can play a mirror package in the moment you match the environment. If the environment is broken, you will fall back to the status of the last mirror package. This is very fragrant.

Summarize

In fact, there are still many other uses, but I just say that everyone is universally used.

The above, the three points mentioned: git private service, document storage service, build a website, I will send a hand to do your hand, truly use the server to improve our work learning efficiency!

Regarding the activities of the free collar server, I will not organize so many people also involve the cash back. Some of the friends do not look at the group information, then directly private letter and I complain, I am really handling, body and mind Too much.

If you want to buy a server, you can purchase this link:

Https://www.aliyun.com/minisite/goods?taskpkg=1111ydsrwb&pkgsid=1959&recordid=962642&usercode=roof0wob

Now is the double eleven event, or the activity price is over, and it will be over in December.

The price is really very cheap now, 60 blocks for new users can buy one year,But I will no longer be cash out, everyone can buy it yourself through the link..

If you want to register a new number, pay attention to real-name certification requires a new ID card.

It is recommended to buy these two servers, which is all, cost-effective.
