Lambda Days
is a one of a kind experience in the functional world.

Never-failing explosion of enthusiasm and talent is what gets us motivated to explore this amazing community in all of its potential. A journey we take through different ideas, technologies, paradigms and languages inspires creativity, growth and pure enjoyment of coding.

To us Scala, Erlang, Haskell, Elixir, F#, Lisp, Clojure, OCaml and many other emerging technologies are more than languages - they are new perspectives on how to understand and tackle challenges of every day work.


Still a student? Contact us regarding discounts and volunteering options. Also: dear Ladies of Lambda - we can't get enough of you!

Last year way too few of you decided to join us, so this year, we have a special deal. Ask your companies if they want to pay your fee.

For each Lambda Lady in a party, everyone gets 10%* off the regular price, adding up to even 50% off the entire order.

* Total discount cannot go over 50%, the offer applies to invoices issued for group reservations per order

(the company receives a discount only for a single order, not for the potential following purchases).

Discounts only apply to the full priced tickets. Contact us directly for details.

Call For Talks

Are you interested in presenting your thoughts on the subject of functional programming? Submit your presentation.

As of now we have identified 6 areas our audience would love to hear about:

Functional languages
Software and system design
Reactive Programming
Web programming
Computation in functional technologies
Applications and case studies

Is your presentation slightly outside that scope? Amaze and inspire us with your submission!

To make our committee’s life easier, this year use Eventil to manage your submissions (both talks and Research Track papers).

If you are interested in publishing your research results related to functional technologies, languages and applications, you can submit your paper to the Research Track.

All papers will be published in two Elsevier journals. The papers focused directly on HPC matters shall be published in Concurrency and Computation: Practice and Experience Journal (IF=1.133). The papers focused on theoretical and language-oriented issues will be published in a special section of Science of Computer Programming (IF=1.064). These special sections are edited by: Wojciech Turek, Aleksander Byrski, John Hughes, Kevin Hammond and Marek Zaionc.

Here are the guidlines for the format of your submission.

Dates for the Research Track:

Manuscript submission - October 31th  November 14th
1st review round - 23 December
Revised version - 20 February
Presentation at the Conference - 23-24 February
2nd review round - 31 March 2018
Final manuscript - 31 May 2018

Deadline: 14/11/2017
