I believe that many working friends will encounter when they want to modify the PDF, but want to modify the PDF but do not have Adobe Professional. That's a bit of a headache, because Adobe Professional needs to purchase a LICENSE. In fact, there are many conversion software or websites in the market, but most of them need to be paid or uploaded to related websites for conversion. The following author recommends some software to everyone. Because it is free for personal.

I believe many friends have used Linux, such as Fedora, RedHat, Ubuntu and other Linux operating systems.   Of course everyone knows that after logging in with ROOT, you can directly control all operations, including creating files and deleting files.   This is really good for some users, but it can be trouble if it is hacked, especially the server administrator. So just think of a way to cancel the ROOT login directly, first create a user who do not have the permssion to create or delete files, and then use this account to control the linux without using the root user directly This is a basic guarantee.

I believe friends who have used Linux Fedora/redhat know that it is easy to set a fixed network in the GUI, but they don't know how to modify it in the text mode.   Setting a static IP for the Fedora system has the advantage of not using DHCP to assign an IP.  It is easier to find the computer you want, especially in a large network. It is most convenient to set a static IP for the computer.   The static IP network address is the most suitable setting for SERVER.

I believe you may also have tried to input content with WORD or EXCEL, and suddenly the computer crashed or crashed. But what you hit was not stored in time. It really hurts at this time. In fact, since MICROSOFT OFFICE 2003, there has been an automatic storage function. As long as your newly opened WORD or EXCEL has content, the software will automatically save it after a certain period of time. So if you didn't save it in time before it crashed or crashed, you can follow the steps below to try to rescue what you typed out with hard work. Of course, La can not be saved, just give it a try.

Have you tried to accidentally remove the language input method in the lower right corner of the computer?   Recently I received this question "I accidentally deleted the language bar on the desktop, how can I get it back?"   I  believes that many people will also have this problem, so I wrote this article.

I recently recorded the steps when I tried to install VMware vCenter Server, version 6.5.   if there is any mistake, please correct me. Thank you
