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.

Hi Andreas,

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

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. Well documented project.

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

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...

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

@altsheets
Sent my remaining SOIL for the ABEESOIL, great project as well!

[AndreasKrueger]

Thanks a lot!

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.

You even mined the money you used. Cool.

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...

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.

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

[Dunkelheit667]

The Oracle was close with 302.96 Kelvin, I think we have had ~ 304 today.

I have sent you the 700 SOIL to your address.

My wallet received the reward, thank you very much!

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

Unfortunately, I'm a bit old school in this regard. Guess this forum is my main 'social media'. However, if someone will ask me about smart contracts IRL, I will share my first experices with your Oracle.

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

Will for sure tinker with SOIL in case something comes to mind that could utilize a smart contract.

Btw. how can I check the balance for my location?

Code:

W.user_getLocationBalance()

Shows 0, but there should be a balance since I've topped up the location.

@all
Try Andreas' project, it's educational and fun.

And useful, 'just' 297.607 Kelvin tomorrow, looking forward to cooling down.

[AndreasKrueger]

Btw. how can I check the balance for my location?

Code:

W.user_getLocationBalance()

Shows 0, but there should be a balance since I've topped up the location.

    city="q=Nanjing,China"
    WEATHER.user_getLocationBalance(city)
        5000000000000000000
    fromWei(WEATHER.user_getLocationBalance(city))
        5

Yes, go for it!

Smart Contract: WeatherForecastAtLocation
New contract v0.5.9 deployed

There was the need to deploy a new contract because:

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.

BUT locations with weather error would have been queried every day, and never stopping,
because the oracle was not rewarded for updating with "weather error" message, and so
the balance was not decreased, and never depleted.

The new contract is fixing that, by rewarding the oracle for the "weather error" message,
so after some days, the location with "weather error" will be on balance zero - and be forgotten.

The good news:
                         The oracle is now auto-updating each location with positive balance.
                         About 24 hours after the last update, all its forecasts are updated with
                         new forecasts, until the balance of that location is depleted.

New contract deployed: Transaction in block 915500  with 43.573% of gas limit.

New contract is at address 0x0c5c4bc449808eee712b1d0858e2b12e71410c8e


Update your contract.js by downloading zip again, overwriting the old one, or:

Code:

cd weathercontract_user
git pull

Please keep on testing!

Btw. how can I check the balance for my location?

Code:

W.user_getLocationBalance()

Shows 0, but there should be a balance since I've topped up the location.

    city="q=Nanjing,China"
    WEATHER.user_getLocationBalance(city)
        5000000000000000000
    fromWei(WEATHER.user_getLocationBalance(city))
        5

Thank you, this did the trick. Just tested with your new contract v0.5.9, working as expected.

293.11 Kelvin minus 272.15 = 20,96 degrees Celsius in Amsterdam, that's correct.

Nice contract Andreas!

[frostminer]

Can i just shoot in how much i enjoy this thread.

Of the tons of threads im watching, this one is a gazillion times more tech heavy and geeky.
Also seemingly a kid-free zone.



While most threads are basicly:

 "%mycoin% TO THE MOON!!11 +silly image + 5 smileys"



SOIL thread is like :
var _remindernote = "Hello!";
var reminderContract = web3.eth.contract([{"constant":true,"inputs":[],"name":"remindme","outputs":[{"name":"","type":"string"}],"type":"function"},{"inputs":[{"name":"_remindernote","type":"string"}],"type":"constructor"}]);

[AndreasKrueger]

Thank you very much, ralfs.

293.11 Kelvin minus 272.15 = 20,96 degrees Celsius in Amsterdam, that's correct.

Very good. It is actually -273.15 Kelvin --> Celsius.

All depends on openweathermap's forecast quality. And weather might always turn out differently.

Nice contract Andreas!

Thanks.

Let us see if the new oracle autoupdate is going to refresh your location ~24hours after the last update. Should be ~tomorrow morning.


For my first test location, it has actually just done it, very nice. You can see that here: http://weathercontract.hopto.org/oracle/

location 24h autoupdates   1

And we have a 2nd 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
                  300 SOIL for the 3rd to finish

So ... who is next?

Does anyone have a way to get in touch with abvhiael ?

I sent a pm a week ago and cannot find an email address... I need to speak to him pretty quickly.

Cheers.

[abvhiael]

I'll have internet hooked up again. Finally! On Friday, and will be back hard at work on SOIL this weekend. Than you all for your patience. Can't wait to get stuff done again. It's been a lonnnnng month.

Im having problems getting nodes.

Any updated list? (already tried the ones in OP)

You can try this one or Andreas' script.

Thanks. Andreas script had 2 new ones.. synching now


edit:
Wow, this synched fast..already got 600 000 blocks

Also, possible to get invite to slack?
