Talk a little
Next Saturday is frost, today in history: on October 17, 1990, the world’s first Internet data database, referred to as “IMDB”, was established in the United States.
This issue includes 2 projects, 3 tools and 2 RT products. I hope they can help you!
1. IRTU GPS – receiving and displaying GPS data based on IRTU project
IRTU GPS is based on IRTU project (an open-source DTU / RTU solution based on universal hardware module), which realizes the reception and display of GPS data. The device PCB is open-source / the server side is open-source / the applet is open-source.

1. The high-performance IO framework based on smart socket can easily support 10W devices online at the same time
2、u8g2_ Wqy – Chinese font suitable for u8g2 graphics library
u8g2_ Wqy is a Chinese font suitable for u8g2. It uses WenQuanYi dot matrix Song typeface as the source, and provides 12×12, 13×13, 14×14, 15×15 and 16×16 dot matrix font libraries.

1. Jenkins – the most popular open source free continuous integration tool
Jenkins is an open source continuous integration (CI) tool that provides a friendly operation interface. It originated from Hudson (Hudson is commercial). It is mainly used for continuous and automatic construction / testing of software projects and monitoring the operation of external tasks.
Jenkins is written in Java language and can run in popular servlet containers such as Tomcat or independently. It is usually used in combination with version management tool (SCM) and build tool.

2. Black duck Protex – a well-known open source code detection tool
Black duck is the first company to develop open source code detection tools (acquired by Synopsys in 2017). Protex platform is an important component of the black duck suite. It provides users with fine-grained (code fragment level) and high-precision open source code detection capabilities. It works based on the black duck knowledge base (KB) and supports localized deployment and use. Can help users:
1. Check the software code and confirm the composition of the code

3. Coverity – well known static code detection tool
Coverity is a fast, accurate and highly scalable static analysis (SAST) solution (the company was acquired by Synopsys in 2014), which can help the development and security team solve security and quality defects early in the software development life cycle (SDLC), track and manage the risks of the entire application portfolio, and ensure compliance with security and coding standards.
