When the limestone of imperative programming is worn away,

Simon Peyton Jones

the granite of functional programming will be observed.

### Projects

Most of them are open-source. Just fork, clone, and contribute!

#### Science

Relativistic electronic structure theory

Density functional theory

Response theory

Molecular response properties

Nonlinear optical properties

Parity violation

Visualization

#### SYMBIOSES

The objective of the SYMBIOSES project is to create an ecosystem based impact assessment and management tool providing fact-based, quantitative analyses of the potential consequences of petroleum developments and other activities in spatially managed ecosystems, mainly focusing on the Lofoten-Vesterålen area.

#### Autocmake

CMake plugin composer.

#### Obara-Saika

Obara-Saika integral code sandbox.

#### Other contributions

#### XCint

Exchange-correlation integrator.

#### DIRAC

Program for Atomic and Molecular Direct Iterative Relativistic All-electron Calculations.

#### OpenRSP

Program for the open-ended calculation of response properties. It connects to response equation solution routines, routines for differentiated one-electron and two-electron integral contributions, and routines for exchange/correlation contributions to enable the calculation of response properties to arbitrary order.

#### Runtest

Numerically tolerant test library for scientific codes.

#### Angstrom-Bohr

Angstrom to Bohr and Bohr to Angstrom conversion without commercials.

#### Space Invaders

A classic game. Unfinished fun project for teaching programming. Also useful for procrastinating something else.

#### Testboard

CDash hosting for scientific projects.

#### Dalton and LSDalton

Together, the two programs provide an extensive functionality for the calculations of molecular properties at the HF, DFT, MCSCF, and CC levels of theory.

#### THUG

Tromsø Haskell Users Group.

#### GPUnCH

Quantum chemistry code for modern hardware with punch.

#### Numgrid

Numerical integration grid for molecules.

#### Gitink

ASCII to SVG Git log graph visualizer. Useful for teaching Git.

#### reFreeze

Markdown web slides served cold. Freeze and thaw Markdown to HTML with Remark and (Frozen) Flask and serve via GitHub pages.

#### Cicero

Serving Great Presentations Since 2015. You do the talking, Cicero does the rendering and serving.
