I'm an industrial control engineer, and right now I'm working on developing motors, digital power supplies, inertial navigation, and braking systems. I've also been involved in projects related to FLASH memory allocator, variable-frequency drive(VFD), microcomputer distributed systems, and hardware abstraction layer(HAL). Plus, they're widely used in urban underground transportation, grid-connected power transmission, and motor parameter testing.
Here's a list of the technologies I’m skilled in:
- Language: C/C++, Python(Maybe), LabVIEW, Simulink(Sorry that it's here).
- Tools: Git, GNU-Collection, GDB, BSD.
- Build: setuptools, make, Kconfig.
- Secure: MISRA, CERT.
- Favorite: Django, Pytorch.
Free software means the users have the freedom to run, copy, distribute, study, change and improve the software.
Free software is a matter of liberty, not price. To understand the concept, you should think of "free" as in “free speech,” not as in "free beer."
More precisely, free software means users of a program have the four essential freedoms:
- The freedom to run the program as you wish, for any purpose (freedom 0).
- The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this.
- The freedom to redistribute copies so you can help others (freedom 2).
- The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.
Developments in technology and network use have made these freedoms even more important now than they were in 1983.
