· Participation process and experience
Looking back on the entire competition process, the biggest difficulty is still in analyzing the competition questions. Since the entry requirements are relatively open, it has become a difficult problem to determine an entry plan that meets the requirements and is outstanding. Through the organizer's explanation of the competition questions and patient answering of questions in the communication group, our final plan gradually became clear. During the development and design process, most members of the team took care of their schoolwork and completed competition tasks at the same time. Although it was hard work, they were all very motivated to put what they had learned to use!
· I say to the community
The server BMC technology stack is an indispensable part of the modern data center. Related technical talents are in short supply, and there are few learning materials available on the Internet. For students, the learning threshold is high and there are few exposure opportunities. The OurBMC community continues to promote the development of BMC software and provides open source projects such as OpenBMC and OurBMC, allowing users to manage servers more flexibly and customizedly. The development of this open source ecosystem not only reduces costs, but also promotes technological innovation and cooperation, bringing more choices and learning opportunities to enterprises and developers.
