The essence of programmer programming is to allow computers to work, while programming languages are the medium for programmers to communic

During Windows Installation and use, a considerable number of junk files are generated, including temporary files (for example :*. TMP ,*. _ MP) log file (*. log), temporary help file (*. GID), disk check file (*. chk), temporary backup files (such :*. old ,*. bak) and other temporary files. In particular, if the temporary ie folder "Temporary Internet Files" is not cleared for a period of time, the cached files sometimes occupy hundreds of MB of disk space. These LJ files not only waste valuabl

Some time ago, I sorted out the computers and networks of the department and produced several "Operation machines", "Test Machines", and "test database servers". These machines must be on at work, in accordance with company regulations or energy-saving requirements, shutdown is required at night. It is very troublesome to manage. If you want to work out an automatic switch, it is very easy to use. Share the following: Automatic bootThe automatic boot function depends on the power management of

I've always felt like my computer is getting slower lately. So want to optimize, but the General software optimization has reached the limit, the streamlining system is not my style. So I began to look for problems like hardware. So I found a good thing--ahci.AHCI (Serial ATA Advanced host Controller Interface) serial ATA Advanced Master interface/Advanced Host Controller Interface) is an interface standard developed by several companies under Intel's

The first step: first from the Oppo r9s desktop to find and click into the "set"-"about the phone,"as shown in the picture. Turn on the phone Step two: On the phone, find the "version number" option, and then quickly click on the "version number"4 times, then you can see the developer Mode/USB Debug mode has been activated prompted. Then return to the settings again, and then reopen "other settings" as shown in the figure. Step three: Finally, the "developer option" that was previously hi

Right click on this computer, choose management when there are the following error, how to solve? Method One 1, we create an empty Word file on the desktop, and then copy the following into Notepad code is as follows Windows Registry Editor Version 5.00 [hkey_classes_root\clsid\{20d04fe0-3aea-1069-a2d8-08002b30309d}\shell\manage\co

1, since is the hard disk partition has the problem we may fix solves, here we Baidu searches a Diskgen tool to repair the error partition table. Hint: This operation is risky and requires careful operation under the guidance of a professional person. 2, now we can only open in the WinPE environment Diskgenius, and then we enter the Diskgenius will see a "hard disk", right select "Rebuild Master boot Record (MBR)"; 3, as shown in the following figure we will see the software rep

The first step, in the mobile phone we find "settings" opened after the entry, details as shown in the following figure. The second step, then in the access interface we find "about the phone" after clicking Open. The third step, open the "Mobile configuration Information" as shown in the following image to open the entry. The fourth step, continuous Click the bottom "version number" seven times (each click has related prompts) as shown in the following figure.

In the use of ghost Win7, we will inevitably appear a variety of operating errors, some may be the day-to-day operation of the more commonly used, and some may be not seen by themselves. Of course, often see the fault is relatively good to solve, and not common to the fault, we will also use browser search or consult others to solve, but if the fault itself can not be very good to describe how to do? What if the failure of others can not understand their own description? In fact, in the face of

Brief comments: This thought very simple, until my naked eye DEBUG8 an hour later, do not think so, just now someone pointed out the error, and then changed well. Using software: Quartus II 9.0 SP2 The experiment also uses ROM, although the experimental instructions are written on RAM, but
