If a query happens while static file is updated it would crash the server.

• switch from Flask to Node to mutualise the co2 model
• compute co2 server side
• map lonlat to country

See #47

Are the bars at the bottom indicating energy exports/imports? i.e. is Germany exporting dirty coal power to France or importing power from France?

Forecasts are fetch with target next/previous multiple of update freq.
Forecast update freq needs to match download freq, else, a phase might appear and out of bounds will be caused.

Error while interpolating wind because current time is out of bounds will appear as error in the console.

Submitted by Bruno:

I'm thinking out loud here, but what about having three ways for the reader to read this map, that could be accessed via three buttons on the top left:

CO2 focus (the default button): Displays your electricity map as it is now, without wind vectors

Wind focus: It displays wind vectors, and the country colored by GW of Wind power produced (shade of blue for instance)

Solar focus: It displays sun irradiance over Europe, and GW of solar power produced by country. Depending on what your datasource for solar irradiance look like, I see two options:
3.1: Solar irradiance as lines of iso irradiance and solar power as shade of yellow over the country area
3.2: or Solar irradiance as shades of yellow over the hole europe map, and solar power per country as a textured fill of black dots (the densier the dots, the more GW).

[ ] Backups

[ ] Access -- how to restrict access to dashboards

• VPN
• OAuth nginx proxy (https://github.com/cloudflare/nginx-google-oauth or https://github.com/bitly/oauth2_proxy)
• Basic/HTTP auth nginx proxy (https://github.com/jwilder/nginx-proxy#basic-authentication-support)

[x] Routing

• use nginx w/ container specific config
• requires SSL and thus DNS
• https://github.com/jwilder/nginx-proxy

[x] Alerts

• expose a /status health check endpoint and check from the outside w/ uptimerobot
• disk space alert? Include in /status?

[x] Monitoring

• docker-grafana-graphite: https://github.com/kamon-io/docker-grafana-graphite
• cAdvistor for docker -> statsD: http://thenewstack.io/wavefront-monitors-containers
• prometheus is no good because it's pull (we want push!)

[x] Orchestration

• where to put all container config? In the repo as .yml files.

[x] Error logs

• just send errors by email
• Could improve with https://hub.docker.com/_/sentry/ & https://docs.getsentry.com/hosted/clients/python/usage/

Show another panel with bars colored by CO2.

Flask should serve only the api
The web content should be accessible through static hosting in github.
Use proper directory structure for this.
A /static or /public folder should do.

Dev console says there's a ; missing on script 1004 File main.js, Line 214, column 24

Seems to be at high cpu usage..

I love the swirling wave patterns but at least in Chrome, it's making the fans spin up at full speed on my Macbook Pro - Activity Monitor verified that it's energy heavy and closing the tab led the fans to stop spinning.

I just get the beachball and nothing happens - computer lags until I close the tab. :(

Also seems to affect mobile version.

• Low winds should be invisible
• medium winds should be colored (only high winds are)
