Tech Talk: Making GHC work for you

abstract: GHC is a state-of-the-art optimizing compiler that is constantly being improved. But despite all of the hard work by the developers, you occasionally find yourself in need of a feature that GHC does not (yet) support. Luckily for us, GHC does have multiple extension points built into the standard compilation pipeline, in addition to […]

Tech talk by Philip Wadler

abstract: We present four calculi for gradual typing: λB, based on the blame calculus of Wadler and Findler (2009); λC, based on the coercion calculus of Henglein (1994); and λT and λW, based on the three- some calculi with and without blame of Siek and Wadler (2010). We define translations from λB to λC, from […]

Tech Talk: Functional programming in Swift

Galois is pleased to host the following tech talk. These talks are open to the interested public–please join us! (There is no need to pre-register for the talk.) abstract: At this year’s WWDC, Apple announced Swift, a new programming language for iOS and OS X development. In this talk, I’d like to give a brief […]

Tech talk: Automatic Device Driver Synthesis

abstract: Automatic device driver synthesis is a radical approach to creating drivers faster and with fewer defects by generating them automatically based on hardware device specifications. I will present the design and implementation of a new driver synthesis toolkit, called Termite-2. Termite-2 is the first tool to combine the power of automation with the flexibility […]

Tech Talk: Verified Cryptographic Implementations

Abstract EasyCrypt is a computer-assisted framework for proving the security of cryptographic constructions. However, there is a significant gap between security proofs done in the usual provable security style and cryptographic implementations used in practice; as a consequence, real-world cryptography is sometimes considered as “one of the many ongoing disaster areas in security. We have […]

Tech Talk: SmartCheck – Automatic and Efficient Counterexample Reduction and Generalization

Abstract QuickCheck is a powerful library for automatic test-case generation. Because QuickCheck performs random testing, some of the counterexamples discovered are very large. QuickCheck provides an interface for the user to write shrink functions to attempt to reduce the size of counterexamples. Hand-written implementations of shrink can be complex, inefficient, and consist of significant boilerplate […]

Tech Talk: Verifying C programs in Coq using VST

Abstract C programs are notoriously difficult to reason about, either for safety or full functional correctness. Even with a program logic powerful enough to prove the necessary properties, the proof has the assumption that the compiler behaves exactly the way it is expected to. Verified Software Toolchain (VST) answers this problem by providing a logic […]

Tech Talk: Vinyl: Records in Haskell & Type Theory

abstract: Records in Haskell are notoriously difficult to compose; many solutions have been proposed. Vinyl lies in the space of library-level approaches, and addresses polymorphism, extensibility, effects and strictness. I describe how Vinyl approaches record families over arbitrary key spaces using a Tarski universe construction, as well as a method for immersing each field of […]
