second request will be executed to the back of the check found that the heavy will be rolled back. In fact, MySQL transactions in the guarantee of data consistency is very OK, but by rolling back to ensure that the only resource exclusive cost too much, do the MySQL transaction testing students know that the transaction in the insert is already inserted, rollback after the deletion.Scenario 2: There is another option is the file exclusive lock in PHP, that is to say that I want to create a new

Recently, I have studied the real-time video network transmission problem of Android. I have spent a lot of effort on video processing. I have summarized the following five solutions and compared them. Take video transmission of 320x240 as an Example Solution Compression rate Compression/Transmission Mode Real-time Average Traffic consumption Transmission Distance Use the callback function of camera to send the original yuv420 data. 0 No compression, frame

Then we will use the culling technology. If you do not use this technology, no matter how many computers make rendering of everything in the scenario. Visible and rendered, as well as rendered. That's silly, right. You have to tell the computer that you can see the rendering. So there is 1. The unity system fr

This visualization program is valid if the encoding can be effectively and correctly executed. "Correct" means that the relationship between the volume of data represented by the visualization program and the data directly reflects the actual data, "effective" means that the visualization program shows the maximum amount of informat

Blue ou iOS training recommendations: some time ago I had organized an article on Cocos2d-x nodes and rendering tree content, so today and everyone to share something really a little similar and close to it! What we need to learn today is how Cocos2d-x uses CCSpriteBatchNode to improve rendering efficiency? If you are interested, you can learn it as a reference! So less talk, directly go to the Introduction interface, previously introduced to you the cocos2d-x of the relevant content, have seen

Beware of GPU memory bandwidth For personal use only, do not reprint, do not use for any commercial purposes. Some time ago, I wrote a series of post-process effect, including the motion blur, refraction, and scattering of screen spance. Most shader is very simple. It is nothing more than rendering a full screen quad to the screen, usually no more than 10 lines of PSCodeAnd does not contain any branch or loop commands. You only need to run sm1.4. However, when you open multiple post processe

The power will be stopped. Except for a bit of heat, there is no loss for the laptop. However, a strange thing happened in just a few minutes: using IE to test JavascriptCodeIt is found that the setinterval frequency is 60 frames/second. This is normal in earlier versions of IE. However, ie9, which keeps pace with the times, seems to be much lower. I tested the clock frequency of various browsers not long ago. I remember that the setinterval of ie9 can reach over 200

above-mentioned hand-painted page, we can find the cup in each frame in the position one by one, so that the animation is called as frame by animation , we need to deal with each frame in the animation. We generally use FPS on the computer (Frames per Second), that is, the number of frames per second to express the animation refresh rate, based on the screen refresh rates and other reasons, on the computer is generally used by the FPS.If the
