FLINT development workshop in Palaiseau, October 2025

Wiki

When and where

• October 27 – 31, 2025
• Bâtiment Alan Turing, campus de l’École polytechnique, Palaiseau, France (location)
  • Mon–Tue : Gilles Kahn room (ground floor)
  • Wed–Fri: Grace Hopper room (2nd floor, at the very back of the building)
• We plan to start around 09:00 on Monday and end between 12:00 and 17:00 on Friday. Feel free to arrive later or leave earlier.

Program

The workshop will focus on coding sprints to develop FLINT and improve FLINT’s integration in other software. Developers of other mathematical software with no direct link to FLINT are also very welcome.

Depending on participant interest, we may arrange a small number of tutorials and technical talks. Feel free to reach out to the organizers with presentation proposals or suggestions for topics you’d like to see covered.

Additional informal talks and public discussions will be scheduled as the need arises.

Where to stay

• Aparthotel Adagio Access Palaiseau Saclay is just around the corner (but the neighborhood is a bit lifeless and it takes some time to get out of it).
• Many hotels in Massy, ~20 min from Polytechnique by bus (line 4606 or 5154 from Massy Palaiseau to Place Marguerite Perey; better option if you want to go to Paris in the evenings.
• Hôtel d’Orsay is located close to Le Guichet RER station, 30–40 min from Polytechnique by foot via Passage du Buisson aka escaliers de la Troche (300+ stairs), or ~30 min by bus (9105 or 4606 from Gare du Guichet to Place Marguerite Perey).

Where to eat

• In the immediate vicinity of Polytechnique: Le 19, Le Living-Room (restaurants), Food Asia Saclay 91 (Asian fast food), Panifique (bakery, closes at 20:00)
• Just a little further: Mangia, Le Julie’s.
• Massy: many restaurants and fast-food options on both sides of Massy-Palaiseau RER station, most decent, none exceptional
• A few restaurants close to Le Guichet station.
• Many more options in Palaiseau (rue de Paris) or Orsay but not as easy to reach.
