Wxpython learning] using the pubsub mechanism to update views Recently, I was busy working on a tool to generate xml packets for testing. In this tool, I have several panels that exist at the same time. One panel is used to manage data dictionaries. It can be edited. Other panels contain a display of these data dictionaries and cannot be edited. They reflect the same data source. At the same time, this tool can also import the transaction table accord

Redis source code analysis (30th) --- pubsub publish and subscribe Mode Today I learned the term "Publish and subscribe mode" in Redis, which was first introduced to JMS (Java Message Service) java Message Service. I subscribe to these types of messages. Only when these types of messages are broadcast and sent Will I filter other messages directly, this ensures an efficient transmission efficiency. Next, let's take a look at how Redis achieves this pu

In recent time, the development of message bus feature was postponed, and some time was spent to optimize and reconstruct the original pubsub mechanism. Here is a record of the optimization process and how it has changed compared to the original design.The role of pubsub within the message busPubSub is primarily used within the message bus for real-time control of all online clients. Each client in the use

= strlen (text);Text[textlen-1] = '; printf ("Server:publishing DATE%sn", text);Nn_send (sock, text, Textlen, 0);Sleep (1);} return 0;} Nanomsg is very simple to use, as long as the direct include nanomsg/nn.h, you can use the basic API. Using the built-in communication mode,need to introduce corresponding header files, such as PubSub mode, the introduction of Nonomsg/pubsub.h can be.PubSub server,

Today, I learned about the tall noun in Redis, "Publish subscription Mode", the word Publish subscription mode was heard in the JMS (Java message Service) Java Messaging Service when I first heard about it. This ranking in a popular point of saying, is that I subscribe to this type of message, when only this kind of message broadcast sent, I will, other messages directly filtered to ensure an efficient transmission efficiency. Let's cut to the chase and learn how Redis implements this publish su

First, using the array cache Subscriber subscription message, when the Subscriber subscribes to the message, push the subscription message to the queue of the specified message, and when the publisher publishes the message, we traverse the execution push to the specified message queue for the callback event.varPubsub= (function(){ vareventobj={}; return{subscribe:function(EVENT,FN) {eventobj[event]=fn}, publish:function(event) {if(Eventobj[event]) eventobj[event] (); }, off:function(EVENT,FN)

Last week, the chromium version library was developed with a focus on many forms-related changes and battery status APIs (Note: Battery status APIs are actually part of the system information API in device APIs) and performance improvement. All unsigned and floating-point array types (Note: itAllows JavaScript to support binary data, You can refer to this Article) now the developer tool will display as a normal array. Obtaining heap snapshots is now 1

For the title of this article, in fact, the literal translation is to create an API endpoint. But, it is really difficult to understand, I still write as API routing bar. Each article, the article, I will all go to carry on the practice operation, strives to write a good point tutorial.This English address-->https://github.com/dingo/api/wiki/creating-

1. Web API Brief DescriptionRecently, many large platforms have exposed web APIs. such as Baidu map Web API, do map related people are familiar. Exposing the service this way makes it easy to integrate functionality with a wide variety of device and client platforms, and to create a richer HTML experience by using JavaScript in the browser. So I believe that the Web API
