Present: Roland, Peter, Keith, Zach, Beyhan, Leo, Gabriele, Yosef

new ET modules: * Zach reviewed FLRW solver, thumbs up for does no harm ** Roland to look at file not found error during compile * no news on Canuda review * Peter is reviewing SelfForce1D, thumbs up for harm * NRPyEllipticET, Leo provided reviewers with parfile ** Leo to contact reviewers

Functionality to retire: * keep ongoing list in wiki * Roland will push pull request that remove use of "REQUIRES THORNS" from current ET thorns

Questions on mailing list: * nothing new

Open tickets: * Zach reported https://bitbucket.org/einsteintoolkit/tickets/issues/2635 that contains a compile time warning about working only with Cartesian grid, suggests removal

* New ticket https://bitbucket.org/einsteintoolkit/tickets/issues/2634/ mentioning lack of documentation on CCTK_BUILTIN_EXPECT

* Two tickets on SummationByParts assigned to Peter, https://bitbucket.org/einsteintoolkit/tickets/issues/2633 and https://bitbucket.org/einsteintoolkit/tickets/issues/2632

* Roland filed a ticket about non-conforming handling of initial data selection parameters https://bitbucket.org/einsteintoolkit/tickets/issues/2631 . Zach provided some recap that setting shift to 0 rather than using LORENE's shift gives better evolution, in particular much less eccentricity. Gabriele suggests adding a comment about this to the gallery example BNS parfile, instead of using LORENE's shift.

* Zach and Gabriele suggest adding warning about this to code, also suggest adding similar runtime warning for other settings that we expect to produce failures or strange results

* Gabriele brought up https://bitbucket.org/einsteintoolkit/tickets/issues/2629 . Had a discussion on how to handle scheduling to compute a quantity every N steps. Roland to send email about what he recollects about doing this in EVOL vs ANALYSIS to the mailing list.

No ET call next week due to overlap with EU ET summer school.
