When viewing the forecast page it's not super obvious which days are more humid than others. There needs to be a way to glean this information at a glace, without having to read and compare the individual temperature vales.

Currently the temperature unit is tied to the country. It's likely that some people will want to view the temperature in the alternate unit. Perhaps the default unit is used unless a cookie says otherwise? Or bake into into the link accept /c or /f` to request a specific unit.

• Implement the location selector on the home page.
• Provide a country select box to narrow the search and pre-select it with the geoip country.

List all the open source libraries that are in use.

So that it's easy to see at a glance when the data was fetched to generate the page.

• dewpoint.7bit.org/src/home.rs

  Line 120 in 297901d

  .expect("FIXME")

• dewpoint.7bit.org/src/home.rs

  Line 170 in 297901d

  .expect("FIXME weather error");

The US is The United States of America for example. Whilst this might be the official name I think it's unexpected in a country drop down.

Add the mobile meta tag to set initial zoom.

It seems to work initially but eventually it starts returning the wrong country.

Requests for the same API data should be cached. https://openweathermap.org/appid#apicare

E.g. https://dewpoint.7bit.org/au/-50.123/150.456/placename

The last component with place name would probably not actually do anything. Perhaps if does not match the canonical label for that location then 301 redirect to the right one to prevent proliferation of variants. It would probably need to be transliterated to ascii and slugified too:

• La Pinçonnière → la-pinconniere

It's possible that this can be pulled from the geocoding result as there is an ascii field in it.

One issue to consider is how to stop bots crawling the whole world through those links?

• robots.txt blocking them
• Possibly some varnish config too
• Maybe require a cookie?

Once things settle down start tagging releases and deploy those to the website instead of main.
