a reusable bottom, need to take more experience. The advantage is that the debugging process is simpler, and you can use Teamscontroller as a test case to test that reusable bottom. I choose the method 3 (not because it is the best, before the code is not much time to choose over 1, more confident when the choice of 2). Only the index function is processed in the refactoring step Step (create function see next article). 1. Write an action to replace Teams/index in the Itemscontroller first. Thi

Configure LVM:If you choose to boot-use the entire disk and set up the LVM partition to create a large volume group to use the disk space. Now you can specify how much disk space should be used for logical volumes/exchanges. It makes sense to leave some room idle and allow you to expand your existing logical volumes later o

This is due a grouping mechanism, which categorize various packages into parent-levels. Gsoftware list acts like a tree and we can navigate into 2 levels. First level displays all the children of the parent category, and at second level each child shows us more info about Itse Lf. Fantastic work in this, it'll sati

1. How to understand the definitionIn Chinese, partitioning and sharding all have the meaning of partitioning. On the big side, the actions performed by these two words are really related to partitioning. Partitioning on many occasions is vertical partitioning abbreviation, then naturally, sharding is horizon partitioning. But at this time, two nouns, vertical and horizon, were introduced. What do you do with vertic and horizon? Where is the difference? 2. Starting from a specific pointTo unders

It provides a high level of portability, as many vendors have started to support kubernetes such as Microsoft, IBM, Red Hat, CoreOS, mesosphere, VMware, etc. If you have tasks that already exist (Hadoop, Spark, Kafka, and so on), then Mesos can provide you with a framework to interleave different tasks, and then add something new, such as a kubernetes application. If you want to use the function Kubernte

By using multi-threading, programmers can use different threads to accomplish specific behaviors, instead of having to adopt the global event loop mechanism, which makes it easy to implement real-time interactive behavior on the network.11.

If you do not log out, the registered Object will be Crash when it is released. Therefore, if necessary, logout in dealloc serves as the final guarantee. 4.
