What about the configuration descriptor? To be honest, it makes no sense to know about the USB flash drive. But as a responsible person, I have to say a few words for it at the moment. One device can have one or more configurations. Have you ever seen a specific USB device? Well, you can see it on a mobile phone.

I read an article about Virtualization of Linux servers over the weekend. This paper tests the performance of several major open-source virtual products, just in line with the isolation performance of several different virtual technologies that I saw some time ago. The performance and isolation of virtual machines are very important performance indicators of virtual technology. It takes a lot of time and effort to test and compare different products in a large area, this article comprehensively

converts the file open from the string to the Data Type
Json can exchange data between different languages, while pickle is only used between python. Json can only serialize the most basic data types. josn can only serialize common data types, such as list, Dictionary, list, String, number, and object type! Josn won't work. Pickle can serialize all data types, including classes and functions.
Example:

As with Side, the introductory six-generation Celeron/Pentium series processor is suitable for pairing with the H110 starter Board:
Celeron G3900/Pentium G4400/Pentium G4500 + H110 motherboard. In addition, the H110 motherboard can also be considered for six generation i3 users with limited budgets.

Using clusters
The main record is the operation of learning Jedis. third, add new nodes to the cluster
Depending on the newly added node type, there are 2 ways to add new nodes to the cluster.
1: If you add a new node that is a master, then we need to create an empty node and then move some hash buckets to this empty node.
2: To add the new node is slave, then we will set the new node as a replica of a node in the cluster.
Add master node Master

support DDR4, such as i3 6100/6300 i5 6500, and so on, mainstream six generations of CPU support DDR4 memory.
AMD platform, there is no one of the AMD processor support DDR4 memory, but AMD will be released this year AM4 interface new CPU will fully support DDR4 memory.
Motherboard, currently only six generation motherboards, Intel's 100 series motherboards, such as B150, Z170 motherboards support DDR4 memory, AMD platform needs to wait
an upgrade is to fully support DDR4 memory, so for the future installed or select a computer friend, It is recommended that the computer with six generation CPU and DDR4 be preferred to get a better experience and not be eliminated easily.
What about Intel's six-generation CPUs? Here's a quick list:
Six generation Pentium series getting started processor recommended: Pentium G4400, Pentium G4500, etc.
Six Daicouri series mainstream processor recommended: i3 6100, i3
