Daily tasks for participants

• List all the things you are working on in the Participant reports section below. Update the list each day. Include things you work on with other people.
• If you want to discuss something with the whole group, add yourself to a Self-organized feedback sessions slot in the schedule above or tell Vaclav (Vashek) Petras.
• For people with triage access and above: If you are or will be working on an issue or on a PR which is not originally submitted by you, assign yourself to the issue or PR. (You can unassign yourself later if you change your mind.)

Participant reports

Per-person reports from the meeting.

Giuseppe Amatulli | Yale University

• Testing r.watershed and r.stream.* for handling large datasets

Veronica Andreo | CONICET - Instituto Gulich

• Complete review of temporal tutorials to push them, GRASS and tutorials websites, GRASS project stuff, understand how new docs work, understand new contribution workflows, interface with R.

Abdullah Azzam | New Mexico State University

Huidae Cho |

• cmake, conda, CI, Mentoring

Edouard Choinière

• Quick ideas, way too much for a week: Helping others (may take a reasonable part of the time), managing CI, setting up localization template updating workflow, backporting tool? Pytest/coverage improvements? Discuss and design other projects, to work on during the year. Open to change on other priorities once there, anything that is useful. Maybe make a little progress on high dpi GUI, especially on Windows.
