Friend Lu recently encountered a problem when installing the Chinese version of Windows XP, he installed the Windows XP system very smoothly, the installation is not normal shutdown. What should we do if this is the case? Of course it's my shot.
The friend's computer configuration is: K6-2 266MHz @300mhz, MVP3 (at board type) motherboard, 160 MB SDRAM (PC100), FUJITSU 10G hard disk, CMI-8330 Isa interface sound card, the video card is the Sis6326,at power supply.
In the past, the original shut
The WIN8 system is mounted on an SSD and hangs a Seagate 2T machine hard drive for data storage, often with abnormal sound. Sounds like power-on power-down. Because of the drive's APM Energy saving, the head is returned to the sound.Use the Crystaldiskinfo software to disable APM and to eliminate the noise. However, disabling APM cannot be saved to the disk firmw

1. What is asynchronous programming?Asynchronous programming is the process of putting time-consuming operations into a separate thread (the thread needs to reflect the execution progress to the interface). Because the time-consuming operation is executed in another thread, it does not block the main thread. After the main thread has opened these separate threads, you can continue to perform other operations (such as form drawing, etc.).Asynchronous programming can improve the user experience an

APM (Application performance monitoring) is a feature of Operations Manager that enables you to effectively capture the problems that occur at the code level when a failure occurs by monitoring the Web application.

The system can not be properly shut down in fact there are many possibilities, such as the following described in several cases.
1. Most likely, and most of the cases, that is the result of a computer virus. It was started by kidnapping the system file registry, causing the computer shutdown button to disappear. All, in the Internet surfing and download network resources, all the time to maintain the security of the system.
2.Windows sound file corruption causes the computer to shut down.

The overall time complexity of this algorithm is O (N3). If it is calculated separately, the complexity is O (N x O x P ). However, when analyzing this code, we may find some strange scenarios:
In the development environment, test data shows that the time complexity of the left branch (N-> M-> Heavy operation) is greater than that of the O and P on the right, so we only saw the left branch in our analyzer.

bottlenecks are temporary and the overall execution time should be reduced as the target bottleneck is eliminated.While it takes a lot of capacity to do a full review of the profile in a Java system, there are some common tools that can help you discover the performance hotspots of your system, including JMeter, AppDynamics, and Yourkit.

But this situation is often impossible, let alone easy to achieve.If you can not reduce the complexity of the algorithm, you can also find the key points in the algorithm and improve the method, to play a role in improving performance. Suppose we have the following algorithm:The overall time complexity of the algorithm is O (N3), and the complexity is O (N x O x P) if calculated in individual access order. But anyway, when we analyze this code, we find some strange scenarios:
