The primary online discussion venue for Julia is the Discourse forum. Discourse is the right place to do any of the following:
Keep up to date on important Julia announcements like language releases and JuliaCon.
Ask a question about any aspect of using or developing Julia or its associated packages and tools. The Discourse forum is the best place to get a fast, high-quality answer to your Julia question. There are subcategories for various Julia application domains such as machine learning, finance, visualisation and GPUs. Questions from newcomers are always welcome: you can use the “first steps” tag to highlight your question as one that would benefit other new users.
Respond to others’ questions: our community thrives when people share their knowledge and experience.
Announce a new package or solicit feedback about something you have been developing.
Advertise Julia-related jobs and community events.
For Chinese users a Simplified Chinese version discourse is also hosted by the community. Please click this Julia中文论坛 link.
The Discourse forum replaced the Julia mailing lists, the largest of which were julia-users and julia-dev, at the end of 2016. Those lists are now read-only but you may like to search them to see if your question has already been raised.
