BOB Conference 2023
“What happens when we use what’s best for a change?”
Berlin, Mar 17
Call for Contributions
Deadline: November 21, 2022

You are actively engaged in advanced software engineering methods, solve ambitious problem with software and are open to cutting-edge innovation? Attend this conference, meet people that share your goals, and get to know the best software tools and technologies available today. We strive to offer a day full of new experiences and impressions that you can use to immediately improve your daily life as a software developer.

If you share our vision and want to contribute, submit a proposal for a talk or tutorial!

NOTE: The conference fee will be waived for presenters. Travel expenses will not be covered (for exceptions see “Speaker Grants”).

Online or Onsite

We expect we’ll be able to hold BOB 2023 in Berlin. Note that we intend to provide a safe environment for all participants. There will be space outside to eat and chat. We may ask you to wear a mask indoors when not presenting or eating, and may also ask you to take a COVID test on-site before the event.

If an on-site BOB is not possible, we’ll make BOB a successful online event, like BOB 2021 and BOB 2022. Should BOB happen online, we will likely ask for pre-recorded talks to make room for questions and social interactions during the actual conference day. (Of course, we’ll provide assistance making those recordings.) Tutorials will likely happen as a live-session.


The program committee offers shepherding to all speakers. Shepherding provides speakers assistance with preparing their sessions. Specifically:

  • advice on structure and presentation
  • review of talk slides
  • assistance with recording
  • review of recording, if applicable

Speaker Grants

BOB has Speaker Grants available to support speakers from groups under-represented in technology. We specifically seek women speakers, speakers of color, and speakers who are not able to attend the conference for financial reasons.


We are looking for talks about best-of-breed software technology, e.g.:

  • functional programming
  • persistent data structures and databases
  • event-based modelling and architecture
  • “fancy types” (dependent types, gradual typing, linear types, …)
  • formal methods for correctness and robustness
  • abstractions for concurrency and parallelism
  • metaprogramming
  • probabilistic programming
  • math and programming
  • controlled side effects
  • program synthesis
  • next-generation IDEs
  • effective abstractions for data analytics
  • … everything really that isn’t mainstream, but you think should be
  • … includeing rough ideas worth discussing.

Presenters should provide the audience with information that is practically useful for software developers.


Furthermore, we seek contributions on successful approaches for solving hard problems, for example:

  • bias in machine-learning systems
  • digital transformation in difficult settings
  • accessibiltity
  • systems with critical reliability requirements
  • ecologically sustainable software development

We’re especially interested in experience reports. Other topics are also relevant, e.g.:

  • introductory talks on technical background
  • overviews of a given field
  • demos and how-tos


We accept proposals for presentations of 45 minutes (40 minutes talk + 5 minutes questions), as well as 90 minute tutorials for beginners. The language of presentation should be either English or German.

Your proposal should include (in your presentation language of choice):

  • An abstract of max. 1500 characters.
  • A short bio/cv
  • Contact information (including at least email address)
  • A list of 3-5 concrete ideas of how your work can be applied in a developer’s daily life
  • additional material (websites, blogs, slides, videos of past presentations, …)
  • Don’t be confused: The system calls a submission event.


  • Direct questions to konferenz at bobkonf dot de
  • Proposal deadline: November 21, 2022
  • Notification: December 5, 2022
  • Program: December 12, 2022
