But there are always limits to what can be expressed. This talk presents Granule, a functional language which pushes these limits by combining linear and indexed types with the recent notion of graded modal types. We'll see examples enforcing privacy constraints, stateful protocols, and verifying properties of standard functional programs just by getting the right type signature.

Marlowe is defined by an executable semantics in Haskell, and has been implemented on the UTxO-based Cardano blockchain. This talk will introduce Marlowe and describe its semantics, implementation and tooling as well as give examples, including some from the ACTUS financial standard. It will also address Marlowe as a Haskell DSL, and describe the choices made in designing and revising the language.

By understanding what he meant by "symbolic violence", "cultural capital" "hexis" etc, we see how each of us influences and is influenced by the people around us, in ways that we wouldn't expect. From this talk, a vulgarized and easy to understand version of Bourdieu's ideas, each of us can seek how to improve the ambience immediately around us Slides & full abstract: https://codesync.global/speaker/romeu-moura/ --- THE SPEAKER - ROMEU MOURA One must imagine sisyphus happy Endless conversation — with friends, compilers — on art, Symmathesy, methods, absurdism, dialectic, paradigm jumps, serendipity.

To best support these new targets, Lumen takes an alternative implementation approach compared to the BEAM - rather than being constructed as a compiler that produces bytecode which is then executed by a virtual machine, Lumen is instead an ahead-of-time compiler that produces native code in the form of a standalone executable. It builds on the capabilities and ecosystem provided by the Rust and LLVM toolchains, and makes it possible to apply BEAM languages to domains that were previously inaccessible. The beta release of Lumen in late August provided an early preview of the new compiler, with primary support for WebAssembly, as well as secondary support for x86_64. This talk will share more about Lumen, where it is currently, and what we have planned for it in the near future and beyond.

Looking back, how many choices we'd change? And how to ensure we make the right one next time? ""The real problem is that programmers have spent far too much time worrying about efficiency in the wrong places and at the wrong times; premature optimization is the root of all evil"" (Donald Knuth). But why does it happen? Why did we do something we didn't really want? Because we acted on assumptions. This talk will guide through a number of war stories where assumptions were made and acted on. There were regrets and disappointments, and we learned to challenge assumptions in the hard way. Now it's time to share what we learnt so far. Slides & full abstract: https://codesync.global/speaker/maxim-fedorov/ --- THE SPEAKER - MAXIM FEDOROV Evil mother of all mistakes Maxim Fedorov is a software engineer at WhatsApp, the largest messaging app. Maxim’s work is focused on performance and scalability of the server-side. Before WhatsApp, Maxim has been developing low-latency TCP/IP applications at NetAlliance (Sydney, Australia), designing Kaspersky Enterprise Security Endpoint (Moscow, Russia), improving Parallels Virtual Automation, called Odin now, at Parallels (former SWsoft), and developing network security software before.

This is especially so for graphs, which can have complex constraints that are difficult to encode using conventional data structures. Join me in the search for a functional, typesafe graph. We will explore different graph representations, and discover how types can help us encode constraints. Using dependent types, we will construct a graph that we can prove satisfies its abstract data type.

Surely it’s the least we can expect from a decent compiler? But when you mix in GADTs, pattern guards, view patterns, data families, strict data constructors, and pattern synonyms, matters get surprisingly tricky. In a 2015 paper “GADTs meet their match” (https://www.microsoft.com/en-us/research/publication/gadts-meet-their-match-pattern-matching-warnings-that-account-for-gadts-guards-and-laziness/) we explored a nice, modular account of pattern-match checking that addresses many of these tricky points. Alas, GHC’s implementation of that paper has proved less than satisfactory: it can be terribly slow, and misses cases that programmers think look obvious. So my colleague Sebastian Graf and I have been radically refactoring the implementation. In this talk, I will give lots of tricky examples of pattern matching, describe how to think about coverage and overlap checking, and reflect on how their new refactored implementation works. Slides & full abstract: https://codesync.global/speaker/simon-peyton-jones/ --- THE SPEAKER - SIMON PEYTON JONES Principal researcher at Microsoft Research https://www.microsoft.com/en-us/research/people/simonpj/#!biography Simon has been a researcher at Microsoft Research in Cambridge, England since Sept 1998. He's also an Honorary Professor of the Computing Science Department at Glasgow University, where he was a professor during 1990-1998. Simon is interested in the design, implementation, and application of lazy functional languages. In practical terms, that means he spends most of his time on the design and implementation of the language Haskell. In particular, much of his work is focused around the Glasgow Haskell Compiler, and its ramifications. Simon is chair of Computing at School, the group at the epicentre of the reform of the national curriculum for Computing in England. Computer science is now a foundational subject, alongside maths and natural science, that every child learns from primary school onwards (background here).
