(1) cgrectinsetCGRect Cgrectinset ( CGRect Rect, CGFloat DX, cgfloat Dy);the application of the structure is centered on the original rect, and then referenced by the Dx,dy to zoom or enlarge. Examples are as follows:CGRect r1 = cgrectmake (100, 100, 50, 50);CGRect R3 = Cgrectinset (r1, 10, 8);//The result should be: 110,108,30,34/************* calculation works as follows ***************R1.ORIGIN.X+=DX;//DX is a positive number is + =, negative is =r

Google advertising revenue calculation formula conjecture variable: s -- display times C -- clicks r -- click rate R = C/s ecpm = mrxm -- Initial serving total X -- ecpm's delivery rate over time, it may be related to the total advertising volume and the total number of clicks on the ad. D -- Revenue calculation: D = S * ecpm/1000 = S * MRX/1000 = S * m * (C/S) *

QPS query per second)Queries per second QPS is a measure of the traffic processed by a specific query server within the specified time. On the internet, the performance of machines serving as Domain Name System servers is often measured by the query rate per second. Terms:QPS = req/sec = number of requests/second [Method for Calculating PV and machines in QPS] QPS statistical method [http_load is generally used for Statistics]QPS = Total number of requests/(total number of processes * request ti

Integer g Calculation formula: (X-1) *4+1024*x=y where X is the value of the integer partition you want to get, the unit is G,y is the number you should enter when you partition, the unit is m, For example, I want to get 3G integer space under Windows, then I should enter (3-1) *4+1024*3=3080, When partitioning, then we should enter 3080 as the partition's size, The equivalent of 10G space should be

Source: Offset Address calculation formula for pure natural FAT1 tables First the FAT table generally has two, the other one for backup. Natural two tables are close to each other, as long as calculated the offset of the FAT1 table and the size of the fat table can be offset by the FAT2 table. Pure Natural The offset address of the FAT1 table is calculated as follows [4]: FAT1 Table offset = number of reser
