Extended Python module series (3) ---- Parameter Parsing and result encapsulation, python ---- In the previous section, we introduced the overall process of extending the Python built-in modules in C language through a simple example. Starting from this section, we will discuss some details in depth, in the detailed discussion, [reference count] is involved from the beginning. First, we will discuss the Par

Introduction In the Google C ++ unit testing (gtest) series of tutorials-assertion and function testing, we learned about assertion statements and how to use test () for function testing, in the use of test (), we are exposed to the way in which a test case contains multiple test instances. Multiple test instances may need to perform acquaintance Data configuration and initialization operations. Therefore, gtest provides test fixture to help us mana

! That's Angularjs's bidirectional data binding, which synchronizes the DOM and model, and so on.This is the online Baidu knowledge theory, now, I am not too clear about the concept of the so-called MV, the following is my experience before writing JS:Angularjs can bind a variable or the value of a property (Model) to a control on a page through the form of {{}}, without having to write JS on its own to manipulate the DOM, reducing the amount of code(What does the update view refer to?) )The fol

At the same time, each of the 2 slice data is separated by 4 bytes (slice data I was directly compared with exploded pictures), by guessing, try to find that the 4 bytes is exactly low to high level of the way the subsequent slice of the length of the data. Since the length of the slice data is recorded in the bundle file, the index in the BUNDLX file must include only the offset of the slice data, wh

1 namenode planning description: Because namenode is very important, once data is lost or the work is stopped, the entire cluster cannot be restored. Therefore, namenode is installed on a single server and deployed separately. Zkfc is responsible for monitoring namenode status information, so zkfc must be installed on each namenode. 2 journalnode planning description: Because journalnode consumes less system resources, journalnode can be set up with

First, Jenkins built-in trigger plug-in1) build after other projects is builtYou can set up multiple dependent jobs and start this build when any of the dependent jobs succeeds. Multiple dependent jobs are used, separated.2) Trigger builds remotely (e.g., from scripts)Specify Token_name in authentication token, and you can then start the build by connecting Jenkins_url/job/jobname/build?token=token_name.3)

Flask developed restful api series (3) and flaskrestful The above two chapters mainly focus on basic configurations. Today we are doing something interesting and adding an avatar image to each customer. If we store images on our own servers, we have high requirements for servers. Every time we download images, we will block Network Interfaces. IF 1000 people access this image at the same time, the entire ne

The event object in Javascript is similar to the derived class inherited from EventArgs class in. NET. It is used to pass status information to the event handler for corresponding operations. This article describes several attributes related to the implementation of the drag-and-drop function in the Javascript event object, and finally encapsulates the differences between the IE event model and the standard DOM event model into a class, to adapt to all browsers. Before reading this article, you

), the worker can detect and select a new leader. In this way, we can understand how a general master-slave distributed system can be scheduled. ZK is a good thing. First, you need to understand the node Creation Mode: Persistent: persistence directory node. The data stored on this directory node will not be lost; Persistent_sequential; Ephemeral: temporary directory node. Once the client and server port of the node is created, that is, the session times out, the node will be automatically delet
