figuring out what the PPI means, we can easily understand the calculation method of the PPI. First, we need to calculate the diagonal equivalent pixel of the mobile phone screen, then we can get the PPI with a diagonal line (we usually call the cell phone screen size the length of the cell phone screen diagonal line. For more information about accurate calculation and publicity, see. Interestingly, the iPhone 4's PPI calculated based on the formula is 330, a little higher than Apple's 326 offic

If you directly set dataformatstring to {0: d}, you will not see the expected results.

The syntax of the dataformatstring attribute is as follows:
Dataformatstring = "{0: Format String }"
We know that {0} In dataformatstring represents the data itself, while the format string after the colon represents the format that we want the data to display; in addition, after the specified format symbol, you can specify the number of digits to be displayed in

Cocos2dx cross-platform engine is really interesting. I recently decided to transfer the game written by oC to cocos2dx.
However, Multi-Resolution on the androd platform is a big problem, which is not called in IOS. 480*320*960*640*1024*768 can be well solved based on pixels.
Fortunately, the setdesignresolutionsize provided on cocos2dx supports multi-resolution, but you will know after using it. If the screen ratio is not 480*320, black borders will appear.

HashMap methods and ideas for solving hash conflicts, hashmaphash
When asked about the hash function, I forgot about it for a while. After a review, I thought the difficulty was nothing more than hash () algorithm design and conflict resolution. It's easy to see this article. I also learned about how JAVA solves conflicts with the HashMap structure.

servers have created this new table. Therefore, once GTID is enabled on all servers, you can enable some slaves to use file-based location and other slaves to use GTID-based location.
This answers the second question: we can make different servers have different replication modes, but all servers must set gtid_mode to ON. When gtid_mode is ON, file-based replication is also run. what does this mean? I have not found any use of this, so in practice, you may only use file-based replication (all s

It takes some time for G7 to be used. When QQ is suspended, it will be automatically disabled in a period of time! The function is that WiFi is automatically disabled, and WiFi is automatically started when the screen is on. At first, I thought it was a problem with QQ Software. Later, it turned out that android enabled the WiFi sleep function.
