The meaning is consistent with the literal meaning, one is the cache table, and the other is the entry in the cache table. Let's look at how the 2 structures are defined below.1, CacheItemThe CacheItem type is used to represent a separate cache entry, the source code is shown below, each field is clearly understandable, and a slightly longer note has been annotated in Chinese.Type CacheItem struct {sync. rwmutex//the item ' s Key.key interface{}//the item ' s Data.data interface{}//how lon

-state drives have a short lifespan? SSD Flash has a problem with the number of write-down limits, which is what many people have criticized for their short lifespan. Flash memory is completely erased once called 1 times P/E, so the life of the flash memory is in P/E units. 34NM of flash memory chip life is about 5,000 times p/e, and 25nm life is about 3,000 times p/e. Does it seem to have a shorter

Einstein thought: "According to the evolution of the show, at any moment in history, allThere is one thing that can be imagined that it is superior to everything else. "This answer is seen in Netherfield DeluoTo be fragile, but "at any moment" poured his deep shock. Does Einstein think that the truthIs it a function of time? This argument destroys the most basic assumptions of all science.But from the history of the whole of science, you will find that the facts of the past are constantly being

I also focus on the expansion of light bulbs and compatibility with smart home systems, of course, the smart home is not really popular, this indicator is not too critical.HueBasic parame

First look at the effect chart. Figure 1 This is a static effect diagram. Figure 2 Here's how to make the steps. 1, first create a missile object model, here do not do detailed introduction. Figure 3 2, then create the particle system emitter and connect with the missile. The Emitte parameters are as follows: Rate =250,emitter Type =directional,spread=0.15,speed random = 4. Next, you create the directional light parameter, the intensity value is set to 0.63, and you add it to the scene an

number, the parent process kills the extra child processes. This parameter should not be set too large. If you set the value of the directive to be smaller than Minspareservers, Apache will automatically modify it to "Minspareservers+1″." MaxClients Limit the number of client-side maximum access requests (the number of concurrent threads per process) for the same time, and defaults to 256. Any requests exceeding the maxclients limit will enter the waiting queue, and once a link is released, t

queue will be serviced. To increase this value, you must increase the serverlimit at the same time. maxrequestsperchild 10000 //The maximum number of requests that each child process is allowed to process during its lifetime, which defaults to 10000. When the Maxrequestsperchild limit is reached, the child process will end. If Maxrequestsperchild is "0", the child process will never end. There are two benefits to configuring Maxrequestsperchild to a non-0 value:1. Ability to prevent (acciden

When the Maxrequestsperchild limit is reached, the child process will end. If Maxrequestsperchild is "0", the child process will never end. Setting Maxrequestsperchild to a value other than 0 has two benefits:1. You can prevent (accidental) memory leaks from being carried out indefinitely, thus exhausting memory.2. Give the process a limited

memory.2. Give the process a limited lifespan, thus helping to reduce the number of active processes when the server load is reduced.worker mode configuration detailedstartservers 2maxclientsminsparethreadsmaxsparethreadsThreadsperchildMaxrequestsperchild 0StartserversThe number of child processes that were established when the server started, and the default value is "3".MaxClientsMaximum number of Access requests (maximum number of threads) that al

order.The TTL field is designed to prevent erroneous IP datagrams from looping over the network, giving IP datagrams a certain lifespan. The IP datagram sets its lifespan in the TTL field when it is sent. The value of the TTL field is attenuated once every time the IP datagram passes through the router. When it is 0 o'clock, The IP datagram is deleted. Usually set to the maximum value of 255.The Protocol f

In this, the particle scientists explain that: quarks are extremely unstable, extremely short-lived particles, which can only be stable within the bound state, but not individual existence.Not only that, but among the more than 300 elementary particles known to the people so far, except for a few stable particles with particularly long life spans, such as photons, neutrinos, electrons, and protons, others are fleeting, that is, they tend to die out in the instant they are born.
