1. First introduction to algorithms Data structures and algorithms are the cornerstones of programs. All the data types we use are a data structure (organizational form of data), and the program logic we write is an algorithm. Algorithms refer to a set of methods used to manipulate data and solve programming problems. For the same […]

Mixing SQL with NoSQL using MariaDB and MongoDB
Suppose you have an application developed on Node.js (or any other platform). This application connects to a MongoDB database (NoSQL) that stores ratings of books (number of stars given and reviews). Let’s also say you have another application developed in Java (or Python, C#, TypeScript…etc.). This application connects to a MariaDB database (SQL, relational) and […]

Powerful Application and Development Skills of JavaScript in Network Music Production, Mixing and Collaboration
1. Introduction With the advent of digitalization, music production is no longer limited to the traditional recording studio. Now anyone with just a computer and the appropriate software can create and share their own music. In recent years, JavaScript has become the language of choice for developing online music production, mixing and collaboration tools due […]
Mixing jpa and mybatis causes thread stuck
Table of Contents background experiment Summarize Background Recently, a problem occurred in the production environment: a certain server node was not working. After observing the detailed logs at that time, it was found that many threads did not appear in the logs after requesting a certain interface. Suppose the request is /query. It means that […]

[FFmpeg actual combat] ffmpeg filter amix mixing realization
Original link: https://blog.csdn.net/weixin_41176628/article/details/104047425 1. Implementation idea The filter filter of ffmpeg has the mixer of amix, which can be used for multi-channel mixing of audio. First of all, we need to compile ffmpeg and install it. It can have encoding function. Consider adding mp3 or aac encoding library. The easiest way is to encode it […]
OpenGL Advanced Mixing
Total experience ?1. An error will be reported when converting from const char to GLchar, so convert the GLchar type to const GLchar. ?2. When SOIL_load_image loads an error, glTexImage2D will report an error code: 1281 when the array of the loaded image is used as a parameter. It is easy to make mistakes in […]
