I. Soil EIGHT practices:Once the SD card is plugged into the system, the kernel will automatically create the device file under/dev/: SDcard. But sometimes the user in the dial out before the card and no umount, the second card in the system created is not sdcard device files, but mmcblk0, MMCBLK1P1, MMCBLK2P1, or MMCBLK3P1.So just use if (fopen ("/dev/sdcard", "r") = = NULL) to detect if the SD card has been captured by the kernel. Then you can mount .... And the things you want to do.How do yo

this. How parallel queries have become serial: The following is a very simple query operation, which, by default, turns on parallelism and, as you can see, opens up 8 threads to compute the SQL statement. Of course, this SQL is a good execution efficiency, CPU time is 622 milliseconds, the total execution time is 130 milliseconds, Do not confuse here, CPU time of 633 milliseconds, 8 CPU total CPU time consumed, greater than the overall executio

much memory is appropriate for the INNODB buffer pool if you want to cache the entire dataset.But most of the time you don't need to do that, you just need to cache the dataset you use frequently.Once you've set it up, let's see how to check if the InnoDB buffer pool size is set enough.In the terminal, execute the following command: $ mysqladmin Ext-ri1 | grep innodb_buffer_pool_reads| Innodb_buffer_pool_reads | 1832098003 || Innodb_buffer_pool_reads | 595 || Innodb_buffer_pool_reads | 915 ||
