Ubuntu usage, debian shows really simple to ugly. It doesn't matter. Familiarize yourself with the vim editor. Nono just joted down two commands! Ctrl+O Save. Enter confirm Ctrl+x to exit. If you exit directly (if you modify the content), you will also be asked if you want to save. Enter confirmation is good. Switch to su root administrator mode! sudo passwd root After executing this command, you will be prompted to enter the root password twice (to make sure that you remember the password). sudo passwd --unlock root Enter the password to unlock the root user Use the command below to switch to root administrator su root Raspberry Pi source swap !!! (Note the pit) The source of the University of Science and Technology of China should be much better. Of course, you are abroad, where there is a problem of changing the source. It wouldn't be so bad! This post is a way to change the source of the University of Science and Technology! Just follow this source swap!!!...

Originally, I had the heart to share some of the URLs I used because I knew the answer. According to the understanding of most Chinese people. This aspect is really lacking! How to say that the problem caused by such a lack of energy lies in the closed language, the closed environment, and the thinking will be defective! There will be a market, business opportunities! These are the programmers behind, the developers. Job. Back to the point. It's a benefit sharing content! Domestic words. Basically,Station B is contracted. iQiyi, Youku has some other drama copyrights. Although in the early years, those of us A station users have always loved the things in this circle. This is a normal channel platform with playback rights. There are also some domestic nameless, carrying, their own code to cover the platform watermark this... A windmill, a dilidili, a cherry blossom, too much more. This kind of building server, climbing through the resources plus their own website watermark. I haven't even seen the private Chinese...

There is no so-called maturity, it is nothing more than a group of people who have experienced despair to let a group of people who have not experienced despair to experience their despair, to win the so-called sympathy and understanding. But the desperate seeker is simply a kind of support and relief. There is no such thing as growth, nothing more than making a change. A person's growth is nothing more than making one change after another. No one likes to change all the time, and one day he will stay in one or find his own comfort zone. (Supplement with January 26 Diary) Things have been forgotten! What I expected, maybe really wrong. There is no such thing as the children of angels with broken arms who snuggle up to each other and try to fly. Nor will there be anyone who likes to protect the weak. The world itself despises the weak. People who see things at a shallow level. Man is born to be alone in the...

Why do we always like to occupy a lot of resources and internal friction when a company starts. And it caused a fight between various departments. And when in order to operate and develop, have to make cost reductions. I see a lot of po owners opening new projects and scaling back old projects in the process of operational development. People are always counting how many words they have entered in their lifetime, but in fact, behind them should be counted what he has deleted. How many times backspaced. (The implication behind this is that one always sees the results of others again, and one should think about how many times he has made mistakes for his answers.) ） Maybe others, (i.e., objective beings, people from God's point of view) will laugh and start with such a big cake and then take it back, which is ridiculous. The passage of time. In fact, the meaning behind many repetitive wheels is that there is no clearer idea and framework at the...

I didn't want to talk about what happened on this site, it was the first domain name I used to make a site. It is not known where he was retrieved for the leak. But have to say. It's boring to have this sort of thing happen. It's not the first time. 1) Top domain names are much more valuable than xyz domain names. XYZ is very unintended to have to say. I would never have imagined that my top site would have a whole bunch of crooked nuts wanting DOSS. 2) But my domestic set of Tencent cloud shell, foreign set of cloudflare shell. Can you find my hosting address? In fact, it is not difficult to find it. It's a pity they can't understand Chinese. I find it boring to take this kind of email disgusting me? In my comments on ads?? 3) Why don't I open comments to block a type of plugin, email can fill my mailbox. I really can't stand it. The average daily traffic...

Of course, the image source is used domestically. Domestic, Tsinghua, University of Science and Technology of China, Ali, NetEase. It's all right. Although I don't want to be the mirror source of Amway University of Science and Technology here, I have to say that they have a tool that is very easy to use. Click here to visit Here you just need to choose https access (save the operator to block http) ipv6/ipv4 depending on your protocol support. However, mobile ipv6 is really problematic. If you don't know, you can choose ipv4 I see the U.S. image source for each version of Debian and Ubuntu.

Sometimes suddenly I can't find what I wrote before. Data is sometimes recovered once. Can't get back what's lost. After all, a snapshot is still a snapshot. Considered replacing the server. Vultr is still a little expensive after a year. Use up the balance first. Will consider, Baidu Cloud, Tencent Cloud, Alibaba Cloud. Build a server in the country. This server doesn't necessarily stop. Will slowly stop. The main problem arises. Consider filing. and website content. Based on the fact that I want to keep a WordPress site. This is preferred with maintenance. Second point. Escrow accounts like GitHub. I have four domain names under my hands. jioushan.xyz (This is the home page.) Once the homepage, it is now changed to GitHub hosted domain name resolution. jioushan.top (hexo homepage) This domain name is still very intuitive to be searched and queried. I did not register com, cn, jp registrars, nationally certified domain names. I also have a domain name jump. riyi.xyz redirect the website to use because of good memory....
