Apologies:

Move repos update

PyOP3 to go into firedrakeproject

Comments on DefElement

DefElement now compares implementations of Finite Elements between Fiat and other sources.

JB: Need to merge Tom Bendall's update of Firedrake BDMC PR

I didn't have sufficient permission

Brought up during Gusto hackathon. Safe to merge FIAT branch- done. FInAT also done. JB merging in master to retrigger tsfc tests - to be reviewed again.

(Later in meeting) All tests passing, to be merged.

JB: Scheduled GH Actions time out after something like 60 days of inactivity

Noticed this when the website wasn't being updated automatically. I think this keepalive workflow would work for us. This is largely a reminder for me to do this, but bringing it to everyone's attention: Rebuilding the website currently requires a manual step

JB to do this

NB: Dualspace PRs

Firedrake: https://github.com/firedrakeproject/firedrake/pull/2294

NB to :

make copy work for Cofunction.
change uses of vector to dat where possible.
Remove case for a ConstantValue in a dual space

Pyadjoint: https://github.com/dolfin-adjoint/pyadjoint/pull/70

Merged.

CW: Homebrew Python seems to be broken

We are failing to install on some machines as the latest homebrew Python cannot programmatically create a venv. It's weird. I have been asking users to install with pyenv instead and even written a wiki article explaining how. Should we recommend pyenv instead of homebrew on the website?

Use 3.11 as example to enable users copypasting.
