. You can use -R /var/www To solve. however, the 777 here is too extreme. It is set simply to confirm that typecho can work normally. The 777 here means that all permissions are granted to everyone (including others) r w e, this is actually unreasonable. According to the official documents, 755 is enough. 2. If typecho prompts "No configuration file can be created automatically", you must manually create a configuration file and copy the configuration code. The permission problem persists. t

Recently find an internship, in doing test assignment encountered such a problem, on the way to record:Said, there are 1 to 100 a total of 100 numbers, put into a circle. Starting from 1, every 1, 2, 3, 4 ... The number takes a number, keeps looping, and finally leaves a few? Specifically, the beginning (0 numbers) Tak

adjustment. Then, in the adjustment process after the red/black tree deletes the node, the maximum number of times the rotation occurs in the cycle of scenario ① will be 1, 2, or 3, the more times you go up, the more rare it is (the number of times the cycle appears according to scenario 1). The maximum number of rotations may reach the tree height, that is, the

diagram One: Nginx startup and memory application process Analysis No program can be separated from start-up and configuration parsing. NGX's code is inseparable from the two core data structures of ngx_cycle_s and ngx_pool_s, so let's analyze it before starting. The memory application process is divided into 3 steps If the requested memory is less than the space remaining in the current block, it is all

We know that a function f can obtain a random number ranging from 1 to 5 with equal probability. How can we obtain a random number ranging from 1 to 7 with equal probability? Int rand7 (){Int;While (A = rand5 () * 5 + rand5 ()> 26 );Return (A-3)/3;} AlgorithmThe idea is:

int rand7() { return rand()%7+1; } int rand10(){ int x=0; do { x=(rand7()-1)*7+rand7(); } while(x>40); return x%10+1;} Analysis: To ensure the even distribution of rand10 () on integers 1-10, you ca
