    Modules JavaScript has a long history of dealing with modular code. Typescript has implemented support for many of these formats since its launch in 2012, but over time, the community and JavaScript specifications have been integrated into a format called es module (or ES6 module). You may know that it is import / export syntax. […]

  • AI reasoning of real-time data stream with wasmedge and YoMo

    Time:2021-7-25

    YoMoIt is a programming framework used to assist developers to facilitate the construction of geo distributed cloud system. YoMo’s communication layer is built on quic protocol, which brings high-speed data transmission. At the same time, YoMo has built-in “stream function” of streaming serverless, which greatly improves the development experience of distributed cloud system. The distributed […]

  • Notes on RT thread learning — (2) analysis of RT thread startup process

    Time:2021-7-20

    In some single-chip software engineering without operating system, in addition to the assembly startup file, it is generally believed that the program entry is the main function, and many program codes are analyzed from the main function. For RT thread real-time operating system, before running to the main function, the program actually carries out a […]
