Dear Haskell Enthusiasts: The LambdaConf 2019 Call for Proposals is open, and we warmly welcome Haskell proposals on topics of interest to aspiring and practicing functional programmers. Historically, Haskell content accounts for more than 50% of content across all 5-8 tracks of the event. Last year’s speakers included Michael Snoyberg, Dana Scott, Jeremy Siek, and many others from both industry and academia. To submit a proposal for LambdaConf 2019, please visit the following website: https://www.papercall.io/lambdaconf-2019 Travel assistance is available, including lodging. ## INTRODUCTION LambdaConf is the largest interdisciplinary functional programming conference in the Mountain West, and one of the largest and most respected functional programming conferences in the world. The conference takes place June 5rd - 7th, in Boulder, Colorado, at the University of Colorado Boulder, and is surrounded by commercial training opportunities. If you are an educator, a researcher, a speaker, a speaker coach, or someone aspiring to one of the preceding, then we warmly welcome you to submit a proposal for LambdaConf 2019. No prior experience is necessary for most proposals, and we welcome beginner-level content. The Call for Proposals closes at the end of January 2019. We recommend submitting as early as you can to ensure sufficient time for editing. LambdaConf attracts everyone from the FP-curious to researchers advancing state-of-the-art; hobbyists, professionals, academics and students. Material at all levels, including beginner content and very advanced content, will find an audience at LambdaConf. Historically, LambdaConf has enjoyed a large selection of sessions on statically-typed functional programming, and a smaller selection of sessions on dynamically-typed functional programming. Some sessions are not tied to specific programming languages, but rather cover topics in abstract algebra, category theory, type theory, programming language theory, functional architecture, and so on, either generically or in a way that applies across many programming languages. ## TOPICS LambdaConf looks for sessions in the following areas: - LANGUAGES. Proposals that overview or dive into specific features of functional, math, or logic programming languages (both new and existing), with the goal of exposing developers to new ideas or helping them master features of languages they already know. LIBRARIES. Proposals that discuss libraries that leverage functional or logic programming to help programmers solve real-world problems. - CONCEPTS. Proposals that discuss functional programming idioms, patterns, or abstractions; or concepts from mathematics, logic, and computer science, all directed at helping developers write software that’s easier to test, easier to reason about, and easier to change safely. - APPLICATIONS. Proposals that discuss how functional programming can help with specific aspects of modern software development, including scalability, distributed systems, concurrency, data processing, security, performance, correctness, user-interfaces, machine learning, and big data. - USE CASES. Proposals that discuss how functional programming enabled a project or team to thrive, or deliver more business value than possible with other approaches. - CHERRY PICKING. Proposals that show how techniques and approaches from functional programming can be adapted and incorporated into mainstream development languages and practices, to the benefit of developers using them. - CAUTIONARY TALES. Proposals that call attention to difficulties of functional programming (both as a cautionary tale but also to raise awareness), especially such proposals that suggest alternatives or a path forward. - EFFICACY. Proposals that present data, measurements, or analysis that suggests different techniques, paradigms, languages, libraries, concepts, or approaches have different efficacies for given specified metrics, which provide actionable takeaways to practicing functional and logic programmers. - OFF-TOPIC. Proposals that have appeal to a mainstream developer audience (the number of off-topic proposals we accept is small, but we do accept some, especially for keynotes). ## SESSION TYPES LambdaConf accepts proposals for the following types of sessions: - LEAP WORKSHOPS (6h). Leap Workshops are approximately 6 hours in length. They are in-depth, hands-on workshops designed to teach mainstream functional programming topics in enough detail, attendees can immediately apply what they learn in their jobs. We require that speakers follow our recommended format for Leap Workshops, although we allow exceptions for experienced teachers. - HOP WORKSHOPS (2h). Hop Workshops are 2 hours in length. Like Leap Workshops, these workshops are in-depth and hands-on, but they cover reduced content and may be specialized to topics that may not have mainstream appeal. We require that speakers follow our recommended format for Hop Workshops, although we allow exceptions for experienced teachers. - DE NOVO SESSIONS (50m). De Novo Sessions are 50 minutes in length. These sessions are designed to present original work from industry and academia. While the requirements for proposals are more rigorous, there is less competition for De Novo slots. - EDUCATIONAL SESSIONS (50m). Educational Sessions are 50 minutes in length. These sessions are designed to clearly and concisely teach one useful concept, skill, aspect, library, or language to attendees. - KEYNOTES (40m). Keynotes are 40 minutes in length, and are presented before all attendees (there are no other sessions concurrent with keynotes). Keynotes are designed to offer thought-provoking, opinionated, and insightful commentary on topics of interest to the community. If you are accepted for a specific type of proposal (e.g. Educational), we cannot guarantee that you will get a slot of this type. Based on scheduling requirements, feedback from the committee, or feedback from your speaker coach, we may require you to change the format of your session. Regards, -- John A.
