# Harmonica Tutorial Transform21

## Planification

- [x] Get a dataset with gravity and elevation (a few thousend points, < 10000)
- We can host it on the repo
- Download it with pooch? Yes
- [x] Create `enviroment.yml` y `test_install.py`
- [x] Start writting notebook(s)
- [x] Make Harmonica and Verde releases
- [x] Preguntar si podemos estar los 3 como instructores
- Matt me dijo que las ponga en la descripción
- [x] Shared notes: Etherpad con titulos especificos para preguntas (NO LO VAMOS A USAR)
- Preguntar si podemos usarlo
- No trabajamos mas en esto, creo que va a ser mejor mantenernos con el canal de Slack y reunirnos en Gather en un horario predefinido.
- [x] Definir office hours para reunirnos en Gather:
- Viernes 11:00 GMT

## Don't forget to mention

- Repositorio
- Pasar link
- Mostrarlo
- Instrucciones
- Notebook
- Instalacion de Anaconda y environment
- Alternativas a Anaconda:
- Colab
- JupyterHub de SWUNG?
- Live en YouTube:
- Pueden pausar y reproducir
- Pueden cambiar la velocidad de reproducción
- Questions:
- Agustina and Andrea will be on Slack channel `#t21-thurs-harmonica`
- Office hours in Gather:
- Friday 11AM GMT?
- Raw schedule? break of 10mins?

### Al final

- Agradecer:
- SWUNG
- StudioX (support)
- Matt (host)
- Filippo (JupyterHub)
- Leo and Fatiando a Terra contributors
- Agustina and Andrea
- Remember office hours in Gather
- Extra resources:
- Links to Fatiando website
- Gradient-boosted equivalent sources
- Preprint
- EGU21
- Invite them to collaborate:
- Find bugs in code and documentation
- Ask for new features
- Write tutorials
- Find open issues to solve
- Open PRs
