GPU asynchronous V-Sync technology program

In 2014, I submitted an internal Intel called "asynchronous Timing" (also known as "asynchronous V-Sync") innovative solutions for the use of GPU to solve the problem caused by the use of V-Sync. But it is a pity that the Intel innovation audit committee did not pass my program, only polite back to a thank you email. This thing was settled, I do not want to think. But a lot of IT news recently introduced AMD in this year's CES on the display of a FreeSync technology, a lot of surprises. I found FreeSyn's AMD technology to solve the problem and take the strategy, and my "asynchronous Timing" design is very similar. I am writing this article to introduce the basic concept of V-Sync...

Thinking about Windows security software

Recently, I re read the several of the windows system security books, at the same time the Internet access to information, quite unexpectedly found that popular a few years ago the great technology, although still books and web page vividly, but most have been unable to in the new system used. I've also had some personal thoughts. Always because of the existence of security risks, there is the attack action, and because there are a lot of attacks, only then have the demand for security protection. So be sure to study the source of security risks. Overall classification, security issues can be divided into local and distributed two, so the method of security attacks can also be divided into local attacks and distributed network attacks. Look at the security problems existing on the local machine, that is, in a installed Windows...

The proliferation of fake Taobao cancer

In fact, every customer is anti fake force. Even those who sell fake sellers, when they become buyers, as well as to fake hate. So the buyers report evidence to crack, is a direct and effective. Moreover, compared with the active crackdown, also more economic cost. No fake coverage reached 100%, or even 50%. If a shop selling 10 fake, and was hit two times, then the shop will not continue to sell all 8 of the rest of the fake, and may take the initiative to withdraw from the risk of a large number of. So fake efficiency is great, the fight and destroy the two or three, it is possible to. But Taobao does not use fake buyers ability.

Wonderful system performance issues (2)

This document is a supplement to the last "fantastic system performance". I experienced the performance of steep drop in the process of trouble, but also met a BSOD. When the blue screen, I was even excited. Because before that, I always thought that the problem was caused by a system or a software module. And blue is just the starting point of the analysis. So when the analysis of this dump, I immediately turned the direction of the judge: it is indeed a bad disk. This conclusion is correct, but not complete. Because the last result is that the disk is not bad, but is subject to the external environment of the interference. This dump file is precious, because under normal circumstances, this hard drive experiment we will not take the initiative to do. So this dump file is completely in the...

It's just a little bit of time today, and it's done. Users can use this tool to view, define the value of IOCTL. If you have an IOCTL, you want to see the specific definition of it. Just put it in the IOCTL value (Hex) edit box input to the value () edit box, and then click analysis button. The value of the analysis is presented in three forms: A numerical form, respectively, by the device, buffer, permissions, functions of these four edit box (combo box) display. One is the picture form, the picture will be IOCTL 32 Bits for the composition of the partition, and display the value of each part. ...
