clojuTRE 2017 & Small FP conf

clojure event for programmers - September 2nd 2017

:about

clojuTRE is a Clojure conference organized by Metosin. The event has single track, late start, short talks (20 minutes and 5 minutes Q&A) and a funky after party for networking, discussions and draft beer. We welcome both newbies and seasoned Clojurists.

Past events: 2016, 2015, 2014, 2013 and 2012.

:location

In Tampere, Finland.

Tullikamarin Pakkahuone
Tullikamarin aukio 2
33100 Tampere
Finland

:coming-from-abroad

You can fly either directly to Tampere-Pirkkala airport (TMP) or Helsinki-Vantaa (HEL). Tampere airport is quite small so you might have better luck finding flights to Helsinki.

From Tampere airport there is a public transport bus connection to Tampere center which takes about 40 minutes and costs 3€. Another option is to take a taxi which takes about 25 minutes and costs about 19€.

From Helsinki airport it is possible to take a train to Tampere. This trip has one transfer and should take about two hours and cost 21€. Tampere railway station is just next to the venue and several hotels.

:staying-at-tampere

Nearly all hotels at Tampere center are within walking distance to the venue.

We will provide discount codes for hotels soon.

:registration

The registration is open

:call-for-speakers

The call for speakers has been closed

The call was closed 21th May. All candidates will be informed by 28th May.

:program

Friday - Small FP conf

Friday is dedicated for presentations about other langauges than Clojure. Are you interested about Elixir, Haskell, TypeScript or something?

Saturday - Main Event

The main event will start at 12:00 and end at 19:00.

Saturday - Afterparty

ClojuTRE will end with a afterparty.

:talks

TBD (Zach Tellman)

Coming later

Clojure Flavoured Devops (Jon Pither)

Getting stuck in battle with command line Sed, AWK, Perl and friends? Trying to provision your cloud environment using good old JSON, and just wish you had some.... you know, data manipulation ability on hand? Do you secretly love Make and just wish you could run adhoc ClojureScript tasks without having to dwell on packages and namespaces, depedencies and requires?

We would like to introduce how we do DevOps and Cloud Provisioning, using Mach - a ClojureScript replacement of Make built on Lumo - and Roll, a ClojureScript wrapped Terraform setup for building you a Blue/Green custom PaaS.

We will also discuss our approach to config - one config to rule them all!

Developing (with) Keechma (Mihael Konjevic)

Last year I've released Keechma - a frontend micro framework for ClojureScript. Since then we've built a bunch of apps with it, and in this talk I'll talk about our experiences and challenges we encountered along the way. I will also cover how Keechma's architecture allowed us to tackle these challenges and the supporting libraries that were written as a result of our experience.

Livecoding the Cloud! (Christophe Grand, Kimmo Koskinen)

Develop AWS lambdas right from the comfort of your repl: no edit-package-deploy cycle, just plain blissful and glorious repl experience. (This talk is unfit for tree-hugging audiences as some violent tree-shaking is depicted.)

Lumo: Bootstrapping a Standalone ClojureScript Environment (Antonio Monteiro)

ClojureScript ships with optional compiler self-hosting since late 2015. Although a feature unbeknownst to many, bootstrapping the compiler represents the next giant leap in Clojure’s reach, raising the number of platforms where it can execute to a new maximum. Lumo is a new, cross-platform, standalone ClojureScript environment that boots instantly and has out-of-the-box access to the entire Node.js ecosystem. Lumo serves many purposes: a fast booting REPL, scripting, build tools, IDE connection through its socket server, and more recently, the ability to compile entire ClojureScript projects with optimizations (thanks to Google Closure Compiler's JavaScript port). This talk covers the lessons learned from building the fastest starting Clojure(Script) environment in existence, shares some of the tricks it employs, and the hurdles that future endeavors intend to overcome. You will discover how easy compiling ClojureScript in ClojureScript actually is , learn about common myths around bootstrapping the ClojureScript compiler, and what Lumo can do for you.

Metaphors We Compute By (Alvaro Videla)

We think in words, we talk with words, we understand the world thanks to words. Metaphors take words to the next level explaining concepts that were escaping our understanding before. In 1980 George Lakoff revolutionised the Linguistic and Philosophic worlds when he studied how metaphors affect our thinking, how they influence our actions and even shape who we are. What happens with the metaphors that we use in the Software Industry?

In this talk we are going to review the importance that metaphors have in our code quality, in the algorithms we choose, and the products we ship.

Scrap your query boilerplate with specql (Tatu Tarvainen)

Specql is a new library for PostgreSQL that introspects your tables at compile time to create clojure.spec definitions and runtime information. Specql provides generic crud operations (including upsert!) with fully namespaced keys.

The talk will showcase the uses of the library with real-world examples and also provide information on how to integrate external information to your clojure.spec definitions.

The Heresy Programming Language, or Learning Through Madness (John Berry)

The author demonstrates the fun and value of experimentation and learning through doing, by presenting key features of the Heresy programming language and how they implement functional programming concepts in unique and possibly questionable ways. Heresy is a BASIC-inspired dialect of Lisp designed originally as a learning tool for functional programming, with a focus on immutability without expense to ease of use.

The Symmetries of Things (Tom Hall)

Symmetry is everywhere, from constraining how builders lay brick to guiding physicists as to the nature of reality.

In the short book The Symmetries Of Things the mathematician John Horton Conway, in his uniquely playful style, classifies all the symmetries of the 2D plane.

In this talk you will learn the Magic Theorem, how many plane symmetries there are, how to identify miracles and wonder-rings and see lots of pretty pictures draw with Quil and a tasty Clojure DSL

Towards Awesome Clojure Documentation (Bozhidar Batsov)

Most developers allegedly hate writing documentation. On the other hand, pretty much everyone considers good project documentation to be a strong indicator of the project's quality. Go figure!

In this session we'll examine the state of the current documentation initiatives and practices in Clojure, some overall problems with documentation in Clojure and some potential solutions. Here's a few topics will touch upon:

  • the various Clojure documentation projects
  • the quality of the official Clojure documentation
  • lessons we can learn from other Lisps when it comes to documentation
  • adopting a common convention for structuring docstrings
  • additional documentation metadata

Documenting things can be fun and extremely rewarding! Join us and find out how!

Bozhidar Batsov@bbatsov, ,

Bozhidar is the maintainer of CIDER and the editor of the community Clojure style guide. Most people would probably describe him as an Emacs zealot (and they would be right). He's also quite fond of the Lisp family of languages, functional programming in general and Clojure in particular.

Believe it or not, Bozhidar has hobbies and interests outside the realm of computers, but we won't bore with those here.
