Roman Numeral Thermometer Notes, Status, Ideas

Weather class "input"

• Reads a REST API, NWS hourly temperature airport KUES (near my house)
• Async
• Returns an integer C unit temp. Probably should return an OutdoorTemperature object directly rather than integer C temp.
• There's many ways to deserialize JSON in C#; in this simple example I used a JsonNode as a DOM
• Probably should use the async deserializer that can work directly with HttpClient
• This Works

OutdoorTemperature class "process"

• Can use C units, F units, or F unit Roman Numerals (Clearly, Romans predate the metric system and as such would use degrees F)
• Has unit tests to verify the conversions and exceptions
• Throws exceptions if fed temperatures outside of World Record ranges with the intent of detecting programmer errors (like trying to store 1014 mb air pressure as a 1014 C temperature)
• This Works

Database class "long term storage"

• Stores OutdoorTemperature object in Azure cloud SQL database.
• Was unhappily surprised to discover Azure SQL database minimum cost is about five hundred dollars per month; cheap per hour for testing, however need an alternative for a longer term experiment.
• This is in progress see github branch "5-database"

Tentative web class "output"

• Cloud
• General idea is something like this mysql query, but translated to mssql query, displayed on a web page: "Select roman from observations where date(timestampcolumn) = subdate(now(), 1) order by celsius desc limit 1" which would be the roman numeral format high temp yesterday, likewise similar queries for low temp, or group by for various intervals etc.
• This is completely speculative at this time
