Smart Contract: WeatherForecastAtLocation
WebView on Oracle Database

The oracle is now checking (every 15 minutes) if there is an > 24 hours not updated location
(with money balance left) - and auto-updates those locations with fresh weather data.

go to: weathercontract.hopto.org/oracle

here we go:

Code:

statusmessage => ForecastWeatherAtLocationAtTime:
forecasted time => Mon, 25 Jul 2016 17:00:00 CEST
temperature => 302.96 Kelvin
pressure => 1016.79 Hectopascal
humidity => 45 Percent
cloudcover => 64 Percent
windspeed => 3.37 Meter/Second
rain => 0.01 Millimeter in 3 hours

Very good, well done.

We have a 1st prize winner:

Testers wanted, for new Smart Contract
1500 SOIL total for the first 3 people to fully try out the quickstart:
   700 SOIL for the 1st to finish
   500 SOIL for the 2nd to finish me
   300 SOIL for the 3rd to finish

I have sent you the 700 SOIL to your address.

Just tested this on a spare Windows PC. Checked your manual02-preparations.md to get an overview, downloaded the repo using Firefox and followed the manual03-console-quickstart.md step by step without any issues.

Good to read that there were no issues at all in Windows.
I had also tested it myself, on a clean droplet in Linux.

Well documented project.

Thanks.

Would you recommend it to others? Then perhaps tweet about it.

Quote from: Dunkelheit667 on July 24, 2016, 10:44:18 AM

Had to mine some SOIL for topping up the location, this took some time.

You even mined the money you used. Cool.

Quote from: Dunkelheit667 on July 24, 2016, 10:44:18 AM

Might be an idea to lower the 'fee' from five to one SOIL during the testing period maybe? Anyway, I could have bought the SOIL on an exchange... Wink

Yes.
And whether you buy or mine - if you get 1 SOIL somehow, you'll also be able get 5 SOIL. Or 50. Or 500.

What else? Yes, the addpeers.js is very usefull indeed. This saved some time as I usually have to copy&paste a list of nodes to get the client running...

True. Saves a whole step.

Everyone: If you only include this one aspect into your system, you are already better off.

Great stuff, have played around with the first smart contract this weekend. Thank you!

That is great. Let us all become makers. Tell us when your the first ideas for novel smart contracts come up in you.

So, who is next, to try out this smart contract? Two rewards are still left.

What to do?

Post the contract answer for the weather forecast of a city of your choice, for one day later.
Write a sentence or two what you think about it, or suggest an improvement in the manual.

Smart Contract: WeatherForecastAtLocation
HyperQuick-Start

get the code

Code:

git clone https://github.com/drandreaskrueger/weathercontract_user.git
cd weathercontract_user

Start gsoil & gsoil console. Load scripts:

Code:

gsoil
gsoil attach

loadScript('useful/addpeers.js')
loadScript("contract/contract.js")
loadScript("contract/tools.js")

TOP UP LOCATION --> wait your and oracle's TX --> ASK FORECAST

Code:

city =   "q=Nanjing,China"
getForecast_message(city)

PRICE
tx = topUpLocation(city, 3); txReceipt = waitForTxReceipt(tx)

admin.sleepBlocks(1); getForecast_message(city)

getForecast(city)
getForecast(city, timestamp_now_plus_hours(24))
getForecast(city, timestamp_now_plus_hours(24 * 3.5))

getForecast_message(city, timestamp_now_plus_hours(24 * 4.5))

Step-by-step explanations in the quickstart manual.

Smart Contract: WeatherForecastAtLocation

Contract deployed. Oracle online.
Quickstart manual.

~~Contract ( v0.5.8 ) is deployed, at address 0xe904c0a8eb49f2fc7185eefde394c42caca028c6~~
Contract ( v0.5.9 ) is deployed, at address 0x0c5c4bc449808eee712b1d0858e2b12e71410c8e
Oracle eventlogloop is listening to its events, and will upload weather data as requested.
Contract ABI is published as contract.js for easy import into console.
Contract tools.js help you to interact with it, on the JavaScript console gsoil attach.
and most importantly:

YOU CAN TRY OUT THE QUICKSTART MANUAL NOW.

Perhaps this is even your first interaction with a real, live, working, innovative SMART CONTRACT ever? Exciting times ...

I have fully tested the preparations and the quickstart manual on a fresh droplet, but please report any issue.

Smart Contract: WeatherForecastAtLocation

Second step:

Prepare your system
- Windows vs Linux, VPS
- Install Soil
- Clone/download repo
- Correct folder
- Add peers
- JavaScript console, with examples
- Languages: Solidity + JavaScript/Python
- Python via RPC, with examples & starterscripts

--> "Text01 Introduction" in post 1.

Has anyone tried the Python part? Does it work for you? Feedback?
