Merchise Startup Circle (http://www.merchise.com/) is delighted to organize the first annual MonadLibre (http://www.monadlibre.com/) conference, an event gathering people passionate about functional programming. We hope to bring together leading practitioners and researchers on all things functional with the Cuban developer community, for an informal forum of deep technical insight and inspiration.

More than just a conference, MonadLibre is also a place where faraway travellers can come to make new friends, share experiences and find renewed hope for writing better software. All Merchise's events are crafted for and with our Cuban community, people who are passionate about learning innovative approaches and technologies to crack the engineering challenges in our industry. People like you!

The first MonadLibre conference will take place from August 10 to 12, three action-packed days of workshops, talks and activities. Merchise Startup Circle warmly invite you to join us in Havana for #MonadLibre (https://twitter.com/hashtag/monadlibre?src=hash) 2016 and to connect with our friendly community in Cuba.

Whilst some well-known experts have already agreed to share their ideas at this year's MonadLibre, we are still open for proposals from you. Sessions may be given in the form of a talk or a workshop. Would you like to share your Functional Programming experience? We'd love to see you featured on this August's program! Please contact us at monadlibre@merchise.com

Stay tuned (http://twitter.com/merchise) for updates on the event schedule and venue!

This is a free event!

----------------------------------

Sessions confirmed so far:

Bartosz Milewski (https://twitter.com/BartoszMilewski) – Parallel and Concurrent Haskell [talk]

Overview of how Haskell deals with parallelism and concurrency: Eval monad, Par monad, Repa, Accelerate, threads, MVars, STM…

Edward Kmett (https://twitter.com/kmett) – Propagators [talk]

Eventually your web application or micro-service has to compute something. We'll explore a fairly powerful framework that subsumes a lot of previous kinds of solvers for different problem domains.

There are a lot of algorithms that revolve around iterating a form of information propagation until it attains a deterministic fixed point. CRDTs, Datalog, SAT solving, functional reactive programming, and constraint programming all fit into this mold.

One framework for these sorts of algorithms is the notion of a “propagator” due to Sussman and Radul, but until now little rigor has applied to know how such algorithms terminate with consistent results. Another framework is Lindsey Kuper’s work on the notion of “lattice variables” (LVars), which addresses termination, parallelism and eventual consistency well, but not iteration.

By blending these frameworks, I’ll build up a series of sufficient conditions for propagators to terminate with consistent results and proceed to show how we can use this common framework to steal insights and quirks from each individual domain to try to optimize the rest.

Richard Minerich (https://twitter.com/rickasaurus) - DSLs in F# [talk]

DSLs enable to you to capture the essence of a problem, guiding you to a solution, and drastically increasing code clarity. Functional languages are ideal for writing DSLs because they offer many tools for modeling your problem and give you the syntactic freedom to capture it in the way you see fit. Type-inferred functional languages give an additional benefit, letting you define your DSLs so that it is difficult or impossible to define your inputs incorrectly. In this talk I will walk you through different kinds of DSLs in F#, and show you the language features that were used in defining each of them.

Richard Minerich (https://twitter.com/rickasaurus) - Entity Resolution in F# [workshop]

Hannes Mehnert (https://twitter.com/h4nnes) - MirageOS - clean-slate robust operating system design [talk]

Contemporary operating systems suffer from being enormous code bases, riddled with bugs, still supporting legacy hardware (like floppy drives). A common attack vector is based on unsafe memory operations - lack of bounds checks (buffer overflows) and temporal memory safety violations (double free, use after free).

But the environment changed: for security reasons, each service is usually isolated in its own virtual machine, and the virtual machines are scheduled by the hypervisor onto the physical hardware. The requirements for operating systems changed, but most operating systems are only extended to support more complex environments.

In this talk I will present a radical approach to operating systems design: back to ring 0, starting from scratch. Programming language technology has progressed since UNIX was written in C, automated memory management is widely used, strong and static types are usable, and we learned how to build reusable libraries and package those.

MirageOS is a library operating system written mostly in OCaml, a functional and modular programming language. It targets hypervisors, thus does not contain hardware-specific drivers, but generic drivers (e.g. a VirtIO network driver). Each MirageOS application consists of only those OCaml libraries required - why should my name server have user management and a file system? The lines of code, and thus the attack vectors, are drastically reduced. We already implemented various common network protocols, such as HTTP, TCP/IP, TLS, DHCP.

I will explain the design and implementation of our TLS stack in more detail, which separates the effectful bits from the protocol logic very clearly, while preserving reasonable performance.

raichoo (https://twitter.com/raichoo) - An X-Ray on GHC[talk]

Haskell is a high level language, in fact it is so high level that it can be hard to wrap your head around what is actually going on on the machine. While this is quite liberating, the curious of us might not be satisfied with this. Let me take you on a ride and show you GHC and Haskell through the eyes of a Hacker. We will take a look at how Haskell code gets compiled to machine code, what optimizations GHC can do for us and some of the more advanced language extensions like GADTs inner workings.

Hannes Mehnert is currently a PostDoc at the University of Cambridge.

In his spare time, he is not only a hacker, coauthor of a book on indian cuisine and functional programming in JavaScript, but also a barista and likes to travel with and repair his recumbent bicycle.

He researches in several engineering areas: from programming languages (such as compiler optimisation visualisation and type systems) over full functional correctness proofs of object-oriented code, development environments for dependently typed languages, to re-engineering network protocols (TCP/IP) and security protocols (TLS, OTR). He feels safe in a garbage collected environment, and appreciates the expressive power of declarative purely functional code.
