*CALL FOR PAPERS / PARTICIPATION* At FOSDEM 2018, LLVM will again participate with a dedicated devroom, on February 4th, in Brussels. As possibly the largest European Open Source Conference, FOSDEM attracts more than 400 lectures and over 5000 hackers - many core contributors of the worlds leading open source projects. Complementing the LLVM developer meetings, the devroom at FOSDEM provides a great opportunity for LLVM developers and the wider open source community to get together, connect and discuss. We invite academic, industrial and hobbyist speakers to present their work on developing or using LLVM, Clang, LLDB, Polly, Compiler-rt, etc. We are looking for: - Keynote speakers. - Technical presentations (30 minutes plus questions and discussion) related to development of LLVM, Clang etc. - Presentations about the use of LLVM, Clang in commercial, academic, hobbyist and other projects. - Tutorials. - Lightning talks (5 minutes). - Demos. The deadline for receiving proposals is November 26th, 2017. Speakers will be notified of acceptance or rejection by December 12th. Please find some advice on what constitutes a good proposal at the end of this CFP. To submit a proposal, please create an account on the FOSDEM interface ( https://penta.fosdem.org/user/new_account). If you already have an account from previous years, please reuse that. Submit your proposal following https://penta.fosdem.org/submission/FOSDEM18, “Create Event”. Please make sure you select "LLVM toolchain devroom" as the "Track”. Presentations will be recorded and streamed. Sending your proposal implies giving permission to be recorded. However, exceptions can be made for exceptional circumstances. *Registration* FOSDEM does not require any registration and is free of charge. *Organization* The mailing list llvm-devroom at lists.fosdem.org can be used to discuss issues of general interest related to the conference organization. Please, do not reply to this email, as it is cross posted to many lists. *Financial support* There may be a possibility of limited funding to help presenting students or presenting contributors who could not otherwise attend the conference. If you need funding to be able to present at the meeting, or can help sponsor, please tell us on llvm-devroom at lists.fosdem.org. *Guidance on writing a proposal for the LLVM Dev Room* This is a guide to help you submit a good proposal and increase your chances of your proposal being accepted. If you have never presented at an LLVM meeting, then do not fear this process. We are actively looking for new speakers who are excited about LLVM and helping grow the community through these educational talks! You do not need to be a long time developer to submit a proposal. General Guidelines: - It should be clear from your abstract what your topic is, who your targeted audience is, and what are the takeaways for attendees. The program committee does not have time to read 10 page papers for each submission. - Talks about a use of LLVM (etc) should include details about how LLVM is used and not only be about the resulting application. - Tutorials on “how to use X” in LLVM (or other subproject) are greatly desired and beneficial to many developers. Entry level topics are encouraged as well. - Typically a few paragraphs are sufficient. Best regards, LLVM @ FOSDEM organisers
