COSCUP Code of Conduct

Since 2006, the COSCUP, Conference for Open Source Coders, Users, and Promoters has gradually developed into an annual event in the Chinese-speaking open-source community. In establishing an open, friendly, diverse, inclusive, and transparent open-source community environment, COSCUP believes that “respecting all people” is the most basic social consensus. On this basis, we promote equal interaction, maintain community values, prevent the occurrence of inappropriate incidents, and avoid any form of discrimination or harassment of all participants. This is the direction COSCUP strives towards, and therefore, the establishment of this Code of Conduct is the concrete implementation of this goal and also a fulfillment of our social responsibility.



COSCUP is an annual conference held by Taiwanese Open source community participants since 2006. It’s a major force of Free software movement advocacy in Taiwan. The event is often held with talks, sponsor and communities booths, and Birds of a feather. In addition to international speakers, many Taiwanese local Open Source contributors often give their talks here. The chief organizer, staffs, and speakers are all volunteers.

COSCUP’s aim is providing a platform to connect Open Source coders, users, and promoters, and promote FLOSS with the annual conference. The conference is free to attend because of the enthusiastic sponsors and donators.

It is a common fact that the coders of traditional commercial software rarely interact with users.

The term “Open Source” appears in 1998, which is familiar to everyone. This kind of developing pattern working on the Internet over 20 to 30 years attributes to many reasons. The key factor may be the direct interaction with coders and users, which forms a rapid feedback and patch system on bugs. This pattern is enlarged by the Internet, where Linus’s law “With enough eyeballs, all bugs are shallow” occurs, thereby the software’s quality enhances. In Open Source pattern, promoters take the position between coders and users, rather than sales and customer service. They package software suites to get installation easier, write documents to lower its learning curve, hold events to spread good software, solve questions from the Internet without creating information asymmetry.

Whoever you are a Open Source coder, a devoted Open Source promoter, a user familiar with Open Source, or even a newcomer, we sincerely welcome you to be a part of COSCUP!
