can be used for this purpose, so that the accuracy of Sleep (1) is increased to 1 millisecond level, then the change:1. Add a reference to the Winmm.lib library. Here I have taken the way to add #pragma comment (lib, "Winmm.lib") statement in the CCApplication.cpp header.2. In the while (1) code snippet, put the Timebeginperiod (1) respectively before and after; Timeendperiod (1); StatementThat would have been finished.After testing, the frame rate is set within the 0 FPS, and the CPU can be us
We often perform a lot of password cracking work for our customers. Sometimes it is because we have cracked a system and looked for repeated use of passwords; sometimes it is because we get statistics on complexity of passwords to prove a certain point of view; sometimes we just try to crack WPA-PSK. However, it is important that you have a safe system. We recently rebuilt our own password cracking server. The following describes some information about its specifications and configurations.

: First, the GPU memory system bandwidth is fast and quite fast. The Core i7 2600K can barely reach the 19gb/s bandwidth. GeForce gtx480 's bandwidth is close to 180gb/s--, which is an order of magnitude! 2nd, the GPU memory system is slow and quite slow. The cache miss for Nehalem (first-generation Core i7) main memory is approximately 140 clock cycles, which is the data (AnandTech given) that is based on the clock frequency divided by memory latency
In the previous part1, I explained the various stages that the 3D rendering command had taken before being actually processed by the GPU on the PC, and then dug a hole here with the instruction processor. OK. In this part, we will indeed encounter the instruction processor first, but you need to know that everything in the instruction buffer goes through the memory-whether it is the system memory or the Display memory. We use pipelines in order, so before entering the instruction processor, we n

Some tests use MySQL5.6.13-community, while others use Percona Server5.6.13.External encryption technology
In this test, without a real vpn, I used the most common method to create a site-site connection-that is, the old SSH channel of Baodao. I didn't find enough devices to build a hardware-accelerated VP
: Background File Download
You can use the '-B' option in the wget command to download files in the background.
Linuxtechi @ localhost :~ $ Wget-B http://mirror.nbrc.ac.in/centos/7.0.1406/isos/x86_64/
CentOS-7.0-1406-x86_64-DVD.iso
Continuingin background, pid 4505.
Output will be written to 'wget-log '.
As we can see above, the download process is captured to the 'wget-log' file in the user's current directory.

Looks like a lot of high-end LGA1155 series CPU processor (2500K, 2600, 2600K, etc.) friends will occasionally encounter the new installation Win7 (x86, x64) in the normal use of general procedures and running the game to trigger the 0x00000124 blue screen error
Zoe since the beginning of the use of snail machine, and sometimes in the running of some programs when the trigger 0x00000124 blue screen error, sometimes a few times a day, sometimes a few
, which can be said to be the philosophy of Go. In the view layer, Go also has the corresponding standard library to provide support, but the more recommended approach is the current more popular MVVM (Model-view-viewmodel): server-side only output JSON, browser DOM as the View layer, the front Javascrip T acts as the contoller part; This not only reduces the server-side resource consumption, but also the intermediate transmission of network traffic, and the front end can be more flexible and ri
2008 to do the test (I will speak later), the latest version for IOMETER-1.1.0-RC1. Here I'll take the latest version to explain. (More options)Iometer includes 2 programs, Iometer.exe and Dynamo.exe. Which Iometer is a control program, is a graphical interface, so that you easily adjust the parameters and display test results, and Dynamo is to allow the test disk to generate pressure test of the main program, with Iometer to control the Dynamo program. When you run Iometer under Windows, you a
