Haskell in industry

Haskell is growing in commercial use. This page collects resources on the industrial use of Haskell.

Haskell in Industry

• ABN AMRO Amsterdam, The Netherlands

ABN AMRO is an international bank headquartered in Amsterdam. For its investment banking activities it needs to measure the counterparty risk

on portfolios of financial derivatives.

ABN AMRO's CUFP talk.

• Aetion Technologies LLC Columbus, Ohio

Aetion is a defense contractor whose applications use artificial intelligence. Rapidly changing priorities make it important to minimize the code impact of changes, which suits Haskell well. Aetion has developed three main projects in Haskell, all successful. Haskell's concise code was perhaps most important for rewriting: it made it practicable to throw away old code occasionally. DSELs allowed the AI to be specified very declaratively.

Anygma is using Haskell to quickly build a prototype of its new content creation platform, targeted towards artists

and designers.

Our team has expertise in all aspects of wireless system design, from the physical and protocol layers to complex networked applications. Antiope Associates's relies on a number of advanced techniques to ensure that the communication systems we design are reliable and free from error. We use custom simulation tools developed in Haskell, to model our hardware designs..

• Amgen

Amgen is a human therapeutics company in the biotechnology industry. Amgen pioneered the development of novel products based on advances in recombinant DNA and molecular biology and launched the biotechnology industry’s first blockbuster medicines.

Amgen uses Haskell;

• To rapidly build software to implement mathematical models and other complex, mathematically oriented applications
• Provide a more mathematically rigorous validation of software
• To break developers out of their software development rut by giving them a new way to think about software.

• AT&T

Haskell is being used in the Network Security division to automate processing of internet abuse complaints. Haskell has allowed us to easily meet very tight deadlines with reliable results.

• Barclays Capital Quantitative Analytics Group

Barclays Capital's Quantitative Analytics group is using Haskell to develop an embedded domain-specific functional language (called FPF) which is used to specify exotic equity derivatives. These derivatives, which are naturally best described in terms of mathematical functions, and constructed compositionally, map well to being expressed in an embedded functional language. This language is now regularly being used by people who had no previous functional language experience.

• Bluespec, Inc. Waltham, Massachusetts

Developing a modern integrated circuit (ASIC or FPGA) is an enormously expensive process involving specification, modeling (to choose and fix the architecture), design (to describe what will become silicon) and verification (to ensure that it meets the specs), all before actually committing anything to silicon (where the cost of a failure can be tens of millions of dollars). Bluespec, Inc. is a three year-old company that provides language facilities, methodologies, and tools for this purpose, within the framework of the IEEE standard languages SystemVerilog and SystemC, but borrowing ideas heavily from Term Rewriting Systems and functional programming languages like Haskell. In this talk, after a brief technical overview to set the context, we will describe our tactics and strategies, and the challenges we face, in introducing declarative programming ideas into this field, both externally (convincing customers about the value of these ideas) and internally (using Haskell for our tool implementation).

• Bug Labs

Bug Labs is using Haskell internally for a number of applications.

• Credit Suisse Global Modelling and Analytics Group New York City, New York

GMAG, the quantitative modelling group at Credit Suisse, has been using Haskell for various projects since the beginning of 2006, with the twin aims of improving the productivity of modellers and making it easier for other people within the bank to use GMAG models. Current projects include: Further work on tools for checking, manipulating and transforming spreadsheets; a domain-specific language embedded in Haskell for implementing reusable components that can be compiled into various target forms (see the video presentation: Paradise, a DSEL for Derivatives Pricing).

• Galois, Inc Portland, Oregon

Galois designs and develops high confidence software for critical applications. Our innovative approach to software development provides high levels of assurance, yet its scalability enables us to address the most complex problems. We have successfully engineered projects under contract for corporations and government clients in the demanding application areas of security, information assurance and cryptography.

• HAppS LLC

Open web development company.

• Hutchin Hill Capital

Positions for Haskell programmers focusing on building infrastructure, applications, and technical support for quantitative equity trading business.

• iba Consulting Gesellschaft - Intelligent business architecture for you

iba CG develops software for large companies:

• risk analysis and reporting solution for power supply company;
• contract management, assert management, booking and budgeting software for one of the worldwide leading accounting firm.

• Informatik Consulting Systems AG

ICS AG developed a simulation and testing tool which based on a DSL (Domain Specific Language). The DSL is used for the description of architecture and behavior of distributed system components (event/message based, reactive). The compiler was written in Haskell (with target language Ada). The test system is used in some industrial projects.

• IVU Traffic Technologies AG

The rostering group at IVU Traffic Technologies AG has been using Haskell to check rosters for compliance with EC regulations.

Our implementation is based on an embedded DSL to combine the regulation’s single rules into a solver that not only decides on instances but, in the case of a faulty roster, finds an interpretation of the roster that is “favorable” in the sense that the error messages it entails are “helpful” in leading the dispatcher to the resolution of the issue at hand.

The solver is both reliable (due to strong static typing and referential transparency — we have not experienced a failure in three years) and efficient (due to constraint propagation, a custom search strategy, and lazy evaluation).

Our EC 561/2006 component is part of the IVU.crew software suite and as such is in wide-spread use all over Europe, both in planning and dispatch. So the next time you enter a regional bus, chances are that the driver’s roster was checked by Haskell.

• Linspire

Linspire, Inc. has used functional programming since its inception in 2001, beginning with extensive use of O'Caml, with a steady shift to Haskell as its implementations and libraries have matured. Hardware detection, software packaging and CGI web page generation are all areas where we have used functional programming extensively. Haskell's feature set lets us replace much of our use of little languages (e.g., bash or awk) and two-level languages (C or C++ bound to an interpreted language), allowing for faster development, better code sharing and ultimately faster implementations. Above all, we value static type checking for minimizing runtime errors in applications that run in unknown environments and for wrapping legacy programs in strongly typed functions to ensure that we pass valid arguments.

Commercial Users of Functional Programming

The goal of CUFP is to build a community for users of functional programming languages and technology, be they using functional languages in their professional lives, in an open source project (other than implementation of functional languages), as a hobby, or any combination thereof. In short: anyone who uses functional programming as a means, but not an end.
