JuliaCon presentations have ranged from introductory to advanced and have been from industry and academia. To get a feel for previous years’ presentations, take a look at our past programmes and recordings: (2014, 2015, 2016, 2017, 2018. We are interested in all topics that have to do with Julia, including the following incomplete list:

• Biology, bioinformatics, health, medicine, and health disparities
• Data analytics and visualization
• Finance and economics
• General computing
• Industrial applications
• Julia’s compiler, tooling, and ecosystem
• Numerical and mathematical optimization
• Scientific computing
• Software engineering best practices
• Statistics, machine learning, and AI

The most important consideration is whether it would be interesting to the Julia community.

Proposal Types

Please note changes from the format of the previous year! This year we have introduced a new style for our workshop. We are taking proposals for half or full day workshops which will be ran on the days before the start of the standard conference. Organizers of such workshops will be given rooms geared towards audience participation, and from this we hope to accommodate interactive tutorial experiences. Workshops are not made to be lectures and will not be recorded on video. The two hour talks which were previously called workshops have been renamed to minisymposia.

• Talks are 30 minutes long, including 5 minutes allocated for questions from the audience.
• Lightning talks are 10 minutes long, including 2 minutes allocated for audience questions.
• Minisymposia (/Extended Presentation) are two hour long in-depth talks on a specific topic. Organizers of a minisymposia can choose to have one or a multiple speakers.
• Workshops are half day (3 hour) or full day (6 hour) interactive sessions. These will be ran on the days before the standard conference in special rooms with laptop accommodations. Topics such as package tutorials and Hackathons.
• Posters are presented during an evening session inspiring discussion and collaboration with the Julia community.
• Birds of Feather are breakout sessions for organized discussions around specific topics. For example, package maintainers can use these times to organize a meeting with and recruit contributors. Or discussion groups for Julia teaching materials or diversity recruitment.

When submitting your proposal (abstract), you may select multiple categories for consideration. Proposals are assigned to presentation types based on amount of high quality material and schedule again ability.

Proposal Advice

• Submit proposals early, as it allows us to contact you and give feedback if necessary.
• When thinking about what makes a good topic, ask yourself what kind of presentation would make you or your friends excited.
• Talk about your own experiences. You could tell us how you use Julia in your work or for a project.
• We are interested in both innovations you developed and restrictions you encountered in Julia.
• It may be a good idea to review previous presentations for inspiration and ideas.
• If you are presenting about a certain project, package, or company, include links to guide the reader to more information.
• Try not to assume familiarity with your subject when writing the abstract; the average reader is most likely not an expert in your area of expertise.
• Avoid opaque titles; while witty titles are good, an informative title is essential. Note you will have a chance to tweak the title after being accepted.
• Avoid infomercials; while we love to hear how you use Julia in your company, JuliaCon is not the place to sell your product.
• If you want feedback before submitting a proposal or if you are interested in the mentorship program, contact us at juliacon@julialang.org well ahead of the deadline.

We look forward to your proposals and to seeing you at JuliaCon 2019!

Submission process

We are using an anonymized submissions process, to avoid selection bias related to the speaker. While enforcing double blind is impossible since most submissions should link to public open source code, all efforts are made to ensure impartial review of submissions.

Recordings and materials

We plan to video record all talks, lightning talks, and minisymposia and will make them available after the conference. We do this for those who cannot attend. If you are uncomfortable with having your talk recorded, however, please let any member of the committee know; being recorded is not a requirement to attend JuliaCon or to give a presentation. Finally, we also ask you to make your materials and recording available under a Creative Commons (default: no commercial reuse) or other open source license.

Proceeding Publications

This year we are offering willing participants the chance to have their work published as part of a JuliaCon proceedings publication. More details forthcoming.

Registration for speakers

Speakers are required to pay the registration fees. Speakers can apply for travel funding and will be prioritized. Fees for workshop organizers will be waived.
