select the/var/lib/nginx/cache directory. If the directory does not exist, you can create it with the correct permissions and ownership:sudo mkdir-p/var/lib/nginx/cachesudo chown Www-data/var/lib/nginx/cachesudo chmod 700/var/lib/nginx/cacheThe levels= parameter specifies how the cache will be organized. Nginx creates a cache key by the value of the hash key (configured below). We chose the above levels to determine the single character directory (which is the last character of the hash value)

is a waste to consume system thread resources. Like a Manger, no poo! Threading is a very valuable resource, creating, destroying, and switching are all quite performance-consuming.When sleep, it is equal to say: Now I do not, but you also do not want to use. You want to use it? To create one yourself.Some people say, sleep does not occupy the CPU Ah! Yes, the CPU is not occupied, but the thread resources, blocking the system's thread scheduling!You can refer to this articleThreads is a limited

In this 1M byte memory space, the lowest 1K bytes are reserved as interrupt vector table extents, and the highest 16 bytes are reserved for the initialization program area.We illustrate th

This problem occurs because in Windows 32-bit system, a process can use a maximum of 2 GB of virtual memory, and the default thread stack stacksize of a thread is 1024 K (1 m ), in this way, when the number of threads approaches 2000, 2000*1024 K = 2G (approximately), memory resources are equivalent to depletion.

The topic is probably to give a few DNA fragments and their respective weights, if a DNA contains a fragment then its value is added to the weight of the fragment, and contains multiple identical DNA fragments are added once, ask the length of the maximum value of the DNA of L.Similar to HDU2825. Dp[i][j][s] represents the maximum value of the length I (Automaton transfer I step), the suffix status of the Automaton J node, the containing DNA fragment for the set S DNA Dp[0][0][0]=0

The approximate program idea is to use the recursive rules to calculate the amount of space occupied by the directory, and then the value of the space to write into the text file, so long as the access to the TXT file will know how much space occupied, do not have to read the disk frequently, save resources. Each time a user uploads a file or deletes a file, it is re-counted. Of course, you can also save the statistical results in the database. Copy the Code code as follows: function Countdirsi

Computer storage unit bit (BIT) (binary digits): stores a bit of binary, that is, 0 or 1, the smallest storage unit. Byte: eight binary bits are one byte (B), the most common unit. That is, 1B (byte bytes) = 8 bit computer storage units are generally represented by B, kb, MB, GB, TB, Pb, EB, ZB, Yb, BB, the relationship between them is: 1 kb (kilobyte kilobytes) = 1024b, 1 MB (megabyte megabytes referred to as "megabytes") = 1024kb, 1 GB (gigabyte gig

(parallel recovery of young generation) is solved, it is easy to handle it. I have checked many articles, the cause of the promotion failed error is that the CMS cannot be recycled (by default, the CMS will be executed only when it accounts for about 90% of the old generation ), the old generation does not have enough space for GC to move some living objects from the young generation to the old generation, so full GC is executed. Cmsinitiatingoccupancyfraction = 70 indicates that CMS is execute

in this case because the formula used is not sufficiently "random"; with a simple summing formula, each incoming byte affects roughly only one byte of the summing register no matter how wide it is. for example, in the second example above, the summing register cocould be a megabyte wide, and the error wowould still go undetected. this problem can only be solved by replacing the simple summing formula with a more sophisticated formula that causes each
