Making Applications With Python

Python is an object-oriented, literal translation of computer programming language. The python syntax is simple and clear, with a rich and powerful class library. Python's design insists on a clear and uniform style, making Python a readable, maintainable, and widely used language that is popular with many users. Recently on Weibo, I saw Liaoche's new Python tutorial, which describes the installation and use of Python in humorous language and video, allowing beginners to quickly master py ...

A common misconception about developing on Google's Android platform is that you must write code in the Java™ language. In fact, you'll have a variety of options with scripting Layer for Android (SL4A) project. SL4A first was a project that completed 20%, and was developed by Google employee Damon Kohler. It took almost 2 years, with 4 major versions. SL4A for many scripting languages ...

R: It's not a real language. Part of the reason we learn about R is that it's not really a programming language. John Cook, an R expert, said: "R is a statistical interactive environment, not a real programming language." It is more helpful to think of R as an interactive environment containing programming languages. "But as Bob Muenchen emphasizes, R is even harder for people who are proficient in SAS and SPSS data tools." About R for analyst ...

PYQT is a toolkit for creating GUI applications. It is a successful fusion of the Python programming language and Qt library.

In mailbox rapid expansion process, one of the performance problems is the MongoDB database level write lock, the time spent in the lock waiting process, directly reflects the user's use of the service process delay. To address this long-standing problem, we decided to migrate a common set of MongoDB (storing mail-related data) to a separate cluster. According to our inference, this will reduce the lock latency by 50%, and we can add more fragments, and we expect to be able to optimize and manage different types of data independently. We start from Mon ...

Editor's note: With Docker, we can deploy Web applications more easily without having to worry about project dependencies, environment variables, and configuration issues, Docker can quickly and efficiently handle all of this. This is also the main purpose of this tutorial. Here's the author: first we'll learn to run a Python Dewar application using the Docker container, and then step through a cooler development process that covers the continuous integration and release of applications. The process completes the application code on the local functional branch. In the Gith ...

The web-based WebSphere MQ telemetry by (MQTT)-related technology provides a bridge between cloud computing and mobile devices to provide you with reliable network services in a low-bandwidth and unstable mobile internet. Cloud computing, mobile Internet, and IoT are the hottest keywords at the moment, and are the key technologies for future development. Cloud computing can provide people with strong computing power and storage capabilities, can effectively solve the mobile device computing capacity and small storage limitations, however, the real ...

Now almost any application, such as a website, a web app and a mobile app, needs a picture display function, which is very important for the picture function from the bottom up. Must have a forward-looking planning picture server, picture upload and download speed is of crucial importance, of course, this is not to say that it is to engage in a very NB architecture, at least with some scalability and stability. Although all kinds of architecture design, I am here to talk about some of my personal ideas. For the picture server IO is undoubtedly the most serious resource consumption, for web applications need to picture service ...
