BOB Conference 2021

"What happens when we use what's best for a change?"


Berlin, February 26

Call for Contributions

Deadline: November 13, 2020

You are actively engaged in advanced software engineering methods,

implement ambitious architectures 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 do know yet whether BOB will happen onsite in Berlin or as an

online event. 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


Speaker Grants


BOB has Speaker Grants available to support speakers from groups

under-represented in technology. We specifically seek women speakers

and speakers who are not be able to attend the conference for

financial reasons.



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



We are looking for talks about best-of-breed software technology,


- functional programming

- persistent data structures and databases

- event-based modelling and architecture

- types

- formal methods for correctness and robustness

- abstractions for concurrency and parallelism

- metaprogramming

- probabilistic programming

- math and programming

- controlled side effects

- beyond REST and SOAP

- effective abstractions for data analytics

- … everything really that isn’t mainstream, but you think should be.

Presenters should provide the audience with information that is

practically useful for software developers.

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


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.

`darcs` is easily my favorite DVCS and `git` alternative. The fact that it's written in Haskell is a nice little extra detail for me

Anyway, I thought that it lacked comprehensive documentation, especially for newcomers, so I wrote a little book https://darcsbook.acmelabs.space

I can see how that part might be a bit "tricky" to get. And it's certainly something that not everyone is looking for. Once you scale up the number of collaborators the situation get more complex though. I've recorded a video on an actual workflow for one of my projects though, maybe this is a bit more insightful: https://hikari.acmelabs.space/videos/hikari-darcs.mp4

I wrote a little article about what motivates us to use #Haskell at http://antei.de. The article is in German, since we currently primarily operate in Germany, but feel free to drop me a line if you have any questions. https://blog.antei.de/posts/2020-09-25-haskell.html

A couple of years ago I've added #dtrace support to `ghc` on #FreeBSD. Learn more about DTrace in my talk at 34c3 #haskell https://www.youtube.com/watch?v=x1wmzxRXOEo
