Calculations of spherical harmonic transforms is a common task for all of us who deal with data distributed over a sphere. Be it a nearly spherical shape of Earth's surface for geophysicists and oceanographers, or a sky -- an apparent location of astronomical objects as seen by an Earth-bound observer -- for astronomers and astrophysicists. Doing it fast therefore matters, as clearly does doing it even faster.

Publish your computer code: it is good enough
Voilà un article qui concerne le calcul scientifique parût dans la
revue Nature. Je vous en rapporte les extraits les plus amusants,
sans plus d'analyse car le sujet est si vaste...
L'auteur, Nick Barnes, qui se déclare "professional software engineer",
est aussi le directeur de la "Climate Code Foundation".
Il passe aux scientifiques le message suivant, résumé dans la phrase
d'accroche : "Freely provided working code — whatever its quality —
improves programming and enables others to engage with your research"

Liberté, Liberté, Liberté et Liberté
Si je ne vous donnais que le titre, et que je vous faisais deviner le
sujet de ce message, je suis sûre que vous ne trouveriez pas du premier
