1, crazy refresh I believe that many people like me before, as soon as they enter the Windows desktop, they start to refresh. Otherwise it is not fun. In fact, many people who came from Dos, Win3.2 know that the earliest Windows opened a resource manager window, the content displayed is the moment of opening, the files in the directory. Suppose you now save a txt in this directory with Notepad, which is not visible in the Explorer and must be manually refreshed. This is the origin of the "refresh" function. The reason why XP and Vista, Win7 can be seen, is because they are automatically refreshed at regular intervals. It’s just that the crazy refreshing of this little action has been learned by many computer novices and is considered to be a must-have for masters. Linux Gnome and KDE and MacOS do not need to be refreshed, nor can they be refreshed. No matter what kind of resource manager tool is used to browse the local directory, no matter what software is used to create or delete files in this directory, it will be displayed in real time without Refresh. Maybe the spray will say: real-time refresh, more waste of system resources. Actually wrong, this is not a real-time refresh, but the file system calls back to the callback function of the resource manager (similar tools, such as the Mac Finder), which is called in the software development industry "observer mode", I think Coder who has learned design patterns understands that advanced is advanced and nothing to argue about. 2, maximize the window I have seen many people, open the resource manager under Windows, even if there is only one file inside, one thing to do is to maximize him (click the maximize button, there are some so-called master double-click on the title bar, There are even some shortcut keys er pressing Alt+space+x). Others, using 21-inch LCD, 1920 * 1080 resolution, browse some web pages with a width of 800, but also maximize the browser, even if the white sides of both sides are wider than the web content. Why bother? I appreciate MacOS's best size button and no maximization design, because I used to have the biggest stink, and now I have turned back. 3, just bought the hard disk (or just bought a new computer) the first pre-partition and everyone, my previous PC also has a partition, C disk installed system, D disk installed software, E disk is the installation program and iso, F disk video Music, G drive is a document for documents and work. It seems to be in good order, and there is no fear that the system will lose important files after reinstalling the system. But when I think about it, do we go the wrong way at the beginning? If you want to keep the files in order, the program is placed in the /Application directory, the movie is placed in the ~/Movie directory, the music is placed in the ~/Music directory, and the document is placed in ~ /Document directory, is not very neat? Why is the system file reloaded lost? Is this not because of the operating system design problem? Then go deep into a stage, why should I reinstall the system? I bought a TV, because I saw An unclean TV station, the TV is smashed and needs to reinstall the system? I bought a refrigerator. Because of the deterioration of the hair that has been put into the refrigerator, the refrigerator is smashed. Do I need to reinstall the system? Under the Mac, the reloading system is No personal files will be lost. Unless you are handcuffed, you have to find a hidden deep "scraping" In addition, my macbook has been used for a year, never reloaded, why should I reload it? Where is he sorry for me? Remember that I used Slic's BIOS, but never activated Windows, why? I don't need 30 days to reinstall the system. Now, finally liberated. 4, the two acquaintances met and asked: 嗨 们 儿, what good anti-virus software? Recently, the topic of the old talk. Some people now say that Linux and Mac viruses are less because of fewer users, and hackers do not bother to develop viruses. I would like to ask you to study the operating system principle a little bit and say good or bad, don't be fooled. Under Windows, developing a virus is too simple. The easiest way to write a batch of delc:ntldr, the system will be paralyzed after execution, although it is easy to recover, but he is too vulnerable. Remember a classic vulnerability in Win2000? In the interface where you need to press Ctrl+Alt+Del, click Help, and then in the help: File-Open, you can access the system files. What does this mean? All security systems are a layer of GUI shells, which are paper tigers. There is no file system level protection at all. Just like a web application, the administrator account password is written in a Javascript script. Under Linux and Mac, if you don't catch a loophole in a particular version of the software, it is completely impossible to write a virus. It is impossible to start. Several of the few viruses in history have been effective for specific versions. And I want to stay in those versions of the user, may have been buried in peace.
There is an example of a car here. PC+Windows is like an old van. There is a bare wire under the dashboard. If a naughty child pulls off one, the car will be finished. Although the eye-catching is easy to fix, if the newbie is wrong, then the entire car circuit system will be finished. The Mac series is like a family car, not a violent means, and I want to break it.
