(web version of this CFP available at https://javier.github.io/data_analytics_devroom_cfp_fosdem_2025/) Welcome to the first edition of the Data Analytics DevRoom at FOSDEM. Our DevRoom will be scheduled on Saturday, February 1st 2025. We will be accepting in-person talks only, with recordings for all the sessions. # About the Data Analytics DevRoom Data Analytics covers a wide range of activities involving data: Ingestion, Extraction, Stream Processing, Open Data Formats, Data Storage, Scientific Libraries, OLAP Databases, Data Quality, Business Analytics, Data Visualization... This DevRoom is a celebration of Open Source Data Analytics projects of all types and sizes. We invite project contributors to present their features, architecture, design, real-world use cases, and integrations. We also encourage end users to share how open-source data analytics projects are helping them solve their everyday challenges. The devroom is a conference-within-a-conference that gives us the opportunity to come together and chat, hack, and share stories about Data Analytics in FLOSS ecosystems. This DevRoom is also an opportunity to identify potential collaborations across projects covering different aspects of the data lifecycle. If you are wondering what type of project would be suitable, this non-comprehensive list of excellent FOSS projects for Data Analytics can give you some clues: Apache Arrow, DuckDB, ClickHouse, Apache Druid, QuestDB, Timescale, Grafana, Apache Superset, Redash, Matplotlib, Seaborn, Bokeh, D3, Graphic-walker, Plots.jl, Makie, Gadfly, Ggplot2, Iceberg, Parquet, Delta Lake, Apache Hudi, LakeFS, Avro, ORC, Presto/Trino, OpenSearch, Valkey, Apache Doris, Pinot, Debezium, Apache Pulsar, Apache Kafka, Apache Flink, Vaex, Scipy, Mumpy, Pandas, Polars, Dask, Dagger.jl, Dataframes.jl, Dplyr, Tibble, Tidyr, Rsample, Broom, Tidyquant, Dbt, Apache Airflow, Dagster, DataHub, Amundsen, Great Expectations, and many more. We want our Devroom to be a safe space for everyone, so we kindly ask all participants to follow the FOSDEM code of conduct https://fosdem.org/2025/practical/conduct/. *** # Call for Papers We welcome submissions about, but not limited to, open source libraries, open source projects, or technical use cases explaining how one (or more) open source components are being used to power real-life use case. Talks featuring more than one open source data project are encouraged. **All programming languages** are welcome. If in doubt, think if the talk you want to submit would be appealing for an audience interested in data analytics. If the answer is yes, please do submit. We are aware some open source projects have also non-open source commercial offerings (we all need to pay the rent!). This Devroom is only about the FOSS part of those projects, so please leave the commercial pitch outside of your proposals and presentations. ## Diversity, Junior Developers, and First-time Speakers We strongly encourage submissions from individuals of all genders, ethnicities, abilities, and backgrounds to foster a diverse and inclusive environment. We also welcome first-time speakers and, if needed, we will be happy to help you rehearse your talk before the event. ## Format of the Talks We will be accepting submissions for 40-minute talks, 10-minute lightning talks, and 5-minute project pitches. Please note that if we don't receive enough submissions, we might not include lightning talks and/or project pitches. You choose the format of your talk. It can be shell-driven, slide-driven, demo-driven, or a combination. If you prefer, you can also present without any screen at all, specifically for the lightning talks and project pitches. If you plan to accept questions, please include them within your allocated time slot. Since we will have a mixed audience, the 40-minute talks will need to feature an intro to make sure everyone can get some context, but you are encouraged to discuss internals of your project or to go as deep as you want into technical details. ## Recording of All the Talks Please be aware of the fact that, barring any technical difficulties, Devroom talks at FOSDEM will be recorded. By submitting a proposal you agree to being recorded and to have your talk made available. *** # How to Submit Your Talk If you would like to submit a proposal, you need to do it via the official FOSDEM website at: https://pretalx.fosdem.org/fosdem-2025/cfp **_When submitting your talk, make sure to select the ‘Data Analytics Devroom’ as the 'Track’._** Please state the type of talk (40-minute talk, 10-minute Lightning talk, or 5-minute OSS Project pitch) in the submission notes. ## Important Dates * Deadline: 2024-11-30 by midnight (Brussels Time) * Announcement of selected talks: 2024-12-15 * Devroom will take place in Brussels, on Saturday February 1st 2025. If you have any special requests for a time slot in case your talk is selected, please add the relevant information in the notes section of the CFP submission. We encourage early submissions to allow ample time for review and feedback. ## Your Profile Be sure to properly fill your profile with: * your name * a short speaker bio * your contact information (for the organizers). If selected, please do remember to include both email and phone as there will be no other reliable form of emergency communication on the day. *** # Contact and Organising Team If you need to get in touch with the organisers of this devroom, please email analytics-devroom-managers at fosdem.org. * Jaromir Hamala, Core Database Developer at https://questdb.io * Javier Ramirez, Data Advocate at https://questdb.io * Ricardo Sueiras, Principal Developer Advocate at https://aws.amazon.com/ --- Thanks and see you all at FOSDEM
