  From 0: 00 on December 30th, the national railway will implement a new train diagram.

  From 0: 00 on December 30, 2019, the national railway will implement a new train operation map. This map adjustment has adjusted some train trips, which will further enhance the railway transportation capacity during Spring Festival travel rush to meet different needs.

  Xi ‘an will start high-speed EMU trains in Xiamen, Datong, Lianyungang and Anqing for the first time. For the first time, two pairs of high-speed trains to Taiyuan were opened in Hefei, and the fastest journey time from Hefei to Taiyuan was 6 hours and 05 minutes. Shenyang Railway is the first high-speed train from Shenyang to Yancheng, Rongcheng and Jilin to Shanghai. Hangzhou East to Chengdu East, Hangzhou East to Xinxiang East, Hangzhou East to Luoyang Longmen, Hangzhou East to Bozhou South opened the first direct high-speed rail.

  In order to meet the needs of large passenger flow capacity in the Yangtze River Delta and North China, six pairs of high-speed trains going to North China via Beijing-Shanghai high-speed railway were added. They are Shanghai-Beijing South G416/5th, Shanghai-Tianjin West G442/1st, Hangzhou East-Tianjin West G446/5th, Ningbo-Beijing South G420/19th, Shanghai Hongqiao-Jinan West G2062/1st, Shanghai Hongqiao-Qingdao North G2066/5th.

  In addition, the running time from Xining to Shanghai has been shortened from 32 hours and 29 minutes to 30 hours and 34 minutes now, with a compression of 1 hour and 55 minutes; The running time from Shanghai to Xining has been shortened from 31 hours and 53 minutes to 28 hours and 29 minutes now, with a compression of 3 hours and 24 minutes. A regular train from Qingdao to Baotou was changed to a direct train, and the adjusted one-way operation time was reduced by at least 1.5 hours.

  After the map adjustment, there are 615 trains stopped at Zhengzhou East Station, which is 126 more than the current map of 489 trains. After the map adjustment, Zhengzhou East Station will increase the number of high-speed trains to Yancheng, Lianyungang, Rizhao West, Huai ‘an, Suqian, Anqing, Ganzhou West and Ruijin, and there will be 124 high-speed trains on the three high-speed railway lines of Zhengzhou-Chongqing, Zhengzhou-Fuzhou and Jinggang, an increase of 40 trains compared with the transition period in the first month of opening.

  The railway department reminds that passengers who plan to travel should pay attention to the 12306 official website and station announcements in time, inquire about the relevant train information, grasp the changes of trains, and make a reasonable ride plan. At the same time, due to the changes in the number and time of some trains after the map adjustment, passengers must carefully check the ticket face information before boarding, so as not to delay the trip.

A group of children’s Christmas wishes were very touching.

Original Lens WeLens

Christmas is only a week away. Who will you spend Christmas with, prepare Christmas gifts and wishes?

A month or two before Christmas every year, a steady stream of letters will pour into 123 Elf Road North Pole, and the recipient is the legendary Santa Claus who will quietly send Christmas gifts to children.

In this letter, children will share their year’s harvest with an old friend they will never meet, and make a wish to post the letter before Christmas, silently expecting that when they wake up on Christmas Day, they can see the long-awaited gift at the bedside.

Of course, this Santa Claus is not real, and letters will not be sent to the North Pole, although many children do believe it. In fact, this is the annual Operation Santa organized by USPS, in order to provide Christmas gifts to families who may not be able to provide more than their basic daily needs.

Children’s Christmas wishes are big or small. Some people want toys, some people want a greeting card, and some people just want a hug, and they don’t forget to tell Santa Claus to wear masks and gloves. ……

??

Want to be happy!

Toys, game consoles and so on are naturally at the forefront of children’s wish list. However, before expressing their wishes, children will also talk about their performance this year.

"I have grown into a good boy this year.

I can count from 1 to 100 and recognize all 26 letters.

I want a cool hot wheels car. "

"I hope you and everyone in the Arctic have had the best year.

I want Lego’s Destiny’s Bounty toy this year.

I have always done well and studied hard at school.

I wish you a safe journey on Christmas Eve. "

"Merry Christmas to you in advance! I know you’re busy,

But I hope you can read this letter.

It was written by my brother and me.

We are all good children, and sometimes we fight.

But we still love each other.

We want to share a Switch together.

I know it will cost a lot of money,

So it’s okay if you don’t get it. "

"I want a real elf friend forever,

He’d better bring a small house with him,

There are beds, toilets, bathtubs, showers and the like.

"Please come and play with me. We can play anything.

If you want to bring me a present, I’ll wear a size 3 dress. "

Some children don’t want gifts, and even want to give gifts to Santa Claus.

"You are the best!

I want to be happy at Christmas! "

"When I wrote this letter to you, I was not very happy.

I hope you can answer a few questions:

1. Am I a vampire?

2. Are you the first person on earth? "

"Please put the gift,

To boys and girls all over the world.

Thank you. "

"I know I didn’t perform particularly well this year.

So it doesn’t matter if my Christmas stockings are empty.

Did someone tell you that you are the best?

I always believed that you were real, and no one else believed you.

They think their parents played you.

……

Please always believe in yourself.

P.S. I want to be the one who gives you a gift, so come on! "

Many children will also put their own paintings on it. Although the level of paintings is uneven, there will be occasional typos, but they are full of sincerity.

????

Please give mom a present, too.

Some children want Santa Claus to give gifts to their mothers or other family members.

"Santa Claus, when you come.

Please give my mother a big hug.

She really needs it. She works too hard. "

"I am writing this letter because I want to do something special for my mother.

Every year, my mother asks me to write down a Christmas wish list.

But we never asked her what she wanted.

My mother likes cooking. She told me that she wanted to go back to school to learn this.

Mom has lost her job, and she has been doing her best.

So if you can, can you give mom a laptop?

So that she can go to school. I really want to achieve this,

She always told me to pursue my dreams,

I also want her to realize her dream. "

"I’m sorry if I misspelled your name,

I want a floating skateboard this Christmas.

But what I want most is my mother.

Work can be smoother, don’t be blamed again.

I think she should be treated well. "

"This year has been too difficult because of the coronavirus.

But I expect to receive some Lego toys.

Because my mother said that she couldn’t give me a present this Christmas,

She hasn’t received her salary for a long time, so she can’t afford anything.

Because she takes care of us, gives us food and works hard.

So I hope she gets something,

Like a Christmas card. "

"I don’t need anything for Christmas,

But my brother needs a new pair of shoes.

His shoes are broken. "

"I wonder if we can make Christmas a day earlier?

Because my father works on Christmas Day,

He is a fireman,

So I’m not at home on Christmas day.

If he can be at home on Christmas day,

We would be very grateful. "

??????

It’s so hard this year ……

This year, everyone has had a hard time, and the children are no exception. So there are also some sad stories in the letter.

"It’s hard this year. I lost my father and grandfather.

My mother is going through a very difficult time.

I hope you can give her some happiness. "

"What I want most this year is that my family can be reunited.

Mom and I are really having a hard time.

Can you help us out?

I hope you can write back to me,

And I want you to know

My family is really important to me. "

What is even more touching is that children still have hope for life.

"Please be careful this year.

You should wear a mask and gloves, because the epidemic remains.

I have some bad news.

My mother and sister died,

My angel dog died, too.

I love her so much!

I lay down next to her and held her until she left.

I shouldn’t be so unhappy in a happy letter.

I remain hopeful and grateful.

You have always given us a lot of support.

My family and I love you very much. Thank you for your efforts. "

"There’s some bad news,

One of my classmates went to heaven because of cancer.

I’m so sad.

But I’m slowly recovering.

Let’s think of something happy _

……

Give everyone a hug, Santa Claus. "

????????

Maybe we don’t need Christmas presents.

There are also many children who say that they don’t want Christmas presents. Because they still have some bigger wishes.

"I don’t think everyone said thank you to you.

You sacrificed your life for the happiness of your children.

That’s amazing. You are really great.

Never forget this.

As for gifts? If I had to choose a gift,

That’s a donation to charity.

Shelters for the homeless, public libraries, anything.

Because what better gift than peace and happiness on earth? "

"This year I want to:

The epidemic is over and the world is at peace.

The climate is under control, and the new X box game machine. "

"P.S., it doesn’t matter if I don’t receive any gifts.

Let’s get everyone fed and clothed before giving gifts. "

I hope you can send toys to the children in the hospital.

And those children who live on the streets. "

"Can you don’t your Christmas present? I just want a card.

I really want a gift,

But I don’t want to be the only one laughing this year.

I hope others can smile,

Like someone who’s homeless.

So please,

What I want this Christmas is

A smile. "

"Dear Santa Claus,

Do you support the LGBTQ group?

If you can talk to God,

Can you tell me that I love him?

Ask him if he still loves me if I’m gay. "

I don’t want anything this Christmas,

But if I may, I also want to ask you a favor:

Please find a cure for Covid-19,

Give it to us and save the world.

Thank you. "

Be a "volunteer" for Santa Claus

In fact, this is the 108th year of Operation Santa Claus.

Every year before Christmas, the post office can receive many letters sent to the nonexistent Santa Claus. In 1912, Frank Hitchcock, the postmaster, wanted to do something good for the community, so he suggested opening and answering these letters to Santa Claus.

At first, only the local post office and citizens wrote letters and gave small gifts to the children who wrote letters. Later, some commercial companies and charities joined in, and gradually formed an annual fixed project-"Santa Claus Action".

"The US Postal Service receives thousands of letters to the North Pole every year.

The workload was too heavy, so Santa asked the post office to find some volunteers to help. "

They set a special address for Santa Claus and began to accept letters one or two months before Christmas. Everyone can write to Santa Claus, but the project will especially help families and children in need. Gifts will be sent before the festival to ensure that the writer can receive them before Christmas.

Over the years, the US post office has received hundreds of thousands of letters. In the past two years, activities have begun to expand to more and more cities. More and more "volunteers" of Santa Claus have joined in, and there are some children among the volunteers.

This year, due to the epidemic situation, the post office simply digitized all the letters it received and published them on the official website USPSOperationSanta.com. People can browse these letters at will and "claim" any number of letters they want to reply to, so as to help the children or families who write letters realize their holiday wishes.

Up to now, more than 20 thousand letters have been claimed this year. Many people are moved and encouraged by the contents of the children’s letters and try their best to help them realize their wishes.

Kim Frum, a spokesman for Santa Claus, said, "This year, more families may be affected financially and emotionally. If you can provide even the slightest help or a spark of happiness to those in need, it means the whole world to them. "

After sending gifts, Santa’s "volunteers" will also receive special commemorative cards.

Indeed, everyone has had a hard time this year. But when I saw the little wishes and great expectations of the children in their letters to Santa Claus, I found that they were still naive and hopeful after this special year.

And this kind of mutual help and persistence in the face of crisis is probably the real meaning of Christmas.

Perhaps, this Christmas, we can not only be the one waiting for gifts, but also help some people in need to realize their Christmas wishes.

Microsoft’s new Bing daily users exceeded 100 million, mainly due to the integration of AI chat bots.

On March 10th, local time on Thursday, Microsoft said that the number of daily users of its bing search engine exceeded 100 million, mainly because the new version of Bing integrated the artificial intelligence chat function, and the number of users of the company’s Edge browser was also growing steadily.

Yusuf Mehdi, vice president and chief marketing officer of Microsoft, said, "We fully realize that our market share is still very small and low, with only single digits." He said that compared with Google, Microsoft’s share in the search market is quite small. "On the other hand, it feels good to go to the dance!"

Google has not published the number of daily users of search engines. However, according to StatCounter, the market share of Google search engines in the United States is usually slightly lower than 90%, compared with 6% or 7% for Bing.

Microsoft said that there are "millions of active users" who are trying out the preview version of Bing with integrated artificial intelligence chat function, and about one third of them are people who have never used Bing before. Microsoft also attributed this to the slow but steady growth of Microsoft Edge browser. Microsoft Edge browser sets Bing as the default search engine. If users insist on switching to other search engines, Edge browser will repeatedly prompt users to switch back to Bing.

A month ago, Microsoft launched the artificial intelligence chat robot function in the limited preview version of Bing, with OpenAI’s Large Language Model (LLM) as the supporting technology. So far, Microsoft has made some adjustments to the behavior of robots to solve the problem that robots sometimes have strange and threatening content in conversations. One of the changes is to limit the number of responses that the chat bot can give in a single instance, because the longer the conversation, the easier it is for the bot’s response to deviate. Recently, Microsoft also introduced some "personalized" functions for chat bots to make the answers more direct or interesting.

Last month, Microsoft began to add "New Bing" function to Edge browser, Skype, Windows 11 taskbar and some development tools. In addition, Microsoft is also testing "multi-modal artificial intelligence" technology, which can handle various forms of input including images, text, audio and video. (Chen Chen)

What is the Internet of Things AIoT?

AIoT intelligent internet of things is artificial intelligence internet of things. AIoT is the abbreviation of AI Artificial Intelligence and IoT Internet of Things. It is an artificial intelligence Internet of Things that collects a large amount of data from different dimensions through the Internet of Things and stores it in the cloud. Based on big data analysis and AI and other technologies, it realizes the digitalization and intelligence of everything. Artificial intelligence is a subject that studies how computers can simulate people’s thinking processes and intelligent behaviors. It is based on bionics, the improvement of algorithm model and calculation speed, and the commonality between human neurons and computer doors (doors are the basic unit of computers). Its strength lies in its learning, reasoning, thinking, planning and other abilities, which ordinary intelligent machines can’t do.

The embedded Internet of Things needs to learn a lot, so don’t learn the wrong route and content, which will lead to a salary failure!

Share a data package for free, almost over 150g. The learning content, face classics and projects are relatively new and complete! It is estimated that it will cost at least dozens to buy some fish.

The Internet of Things refers to the real-time collection of any object or process that needs to be monitored, connected and interacted through various devices and technologies such as information sensors, radio frequency identification technology, global positioning system, infrared sensors, laser scanners, etc., and the collection of all kinds of required information such as sound, light, heat, electricity, mechanics, chemistry, biology, location, etc., and the realization of ubiquitous connection, identification and management between things and people through various types of network access. Through this definition, we can feel that this will be a huge database, and the learning process of artificial intelligence also needs a lot of data information. Obviously, this is a link between artificial intelligence and the Internet of Things, which can link them together and play a greater role.

In short, the Internet of Things (IoT) uses terminals with different protocols to carry out information interaction and intelligent processing through a certain agreed protocol, while artificial intelligence can keep learning and become more and more intelligent with data. If artificial intelligence is software, it needs the Internet of Things as a carrier, and if it is hardware, it needs artificial intelligence to drive it. Therefore, we can also regard the Internet of Things as a carrier of artificial intelligence.

The Internet of Things is an important part of the new generation of information technology. The English name is "The Internet of things". Therefore, as the name implies, "the Internet of Things is the Internet of Things". This has two meanings. First, the core and foundation of the Internet of Things is still the Internet, which is the expansion and expansion network based on the Internet. Secondly, its clients expand and expand between any goods, and exchange and communicate information.

What can one server do?

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.
