@BitSpread_twitter just download the new one and run

@makoto
@alexvandesande btw are there any diagram that explains the relationship of various component (mist, geth, solidity, web3, etc) to newbies? I have our study group this evening, so I thought I should give some 15 min super intro to go through terminologies
Alex Van de Sande
@alexvandesande
@makoto unfortunately no. But if you build one it be helpful
Makoto Inoue
@makoto
I remember someone from ConsenSys made one but cannot remember the url :(
Alex Van de Sande
@alexvandesande
solidity: language
web3: javascript object used to connect to the node and compile solidity
geth: runs the node, connects to the network, execute transactions. The meat.
wallet: a dapp that uses web3 to watch wallets and send transactions
mist: an electron app that allows you to use html apps on ethereum. Currently only displays the wallet app

@makoto
yeah, that's the minimum you need to know, I guess
Sriram Kumar
@batteringram01
Yeah I can help @makoto @alexvandesande I was thinking the same.
Alex Van de Sande
@alexvandesande
Thanks @makoto please post the result on reddit.com/r/ethereum !

@makoto
I made a quick one at https://docs.google.com/presentation/d/16KBFTskiBovLY2NL_JCPNEWObQ8iPxbB181mc0_WaKU/ Any comments welcome before I post on reddit
Alex Van de Sande
@alexvandesande
@makoto that’s very good. Accurate, no comments.

Hi, What should I do if I forgot password of my wallet? :worried:
Alex Van de Sande
@alexvandesande
@XuannyLee take a meditative walk and try to remember it. If there’s a substantial amount of money, contact a wallet brute force specialist to try to extract it for you. Be careful and find someone with a high reputation
There’s no way for anyone else to recover or change it

Hey nice to meet everyone!

Which frameworks (if any) are people using to build dapps right now? Is meteor still a good choice?
I'm looking at embark and truffle as frameworks choices. Anyone developing with them right now?

@BitSpread_twitter
Thanks @alexvandesande
Not sure it is a OS issue, but using the latest Mist downloadable Wallet 0.7.2, we noticed issues on Mac when transferring Digital Tokens. Tokens were "sent" and did not appear in transactions. We had enough gas to make the transfer. It seems to work on Windows. Has anybody got the same issue?

@alexvandesande thank you for that.
XuannyLee
@XuannyLee
@alexvandesande Thank you.

@bitcoinmeetups
It would be nice to see this page updated with some images and perhaps another UI. It's important that Ethereum gets high quality and abundant Dapps that do get exposure. http://dapps.ethercasts.com/

Q: Contract with 2 owners. One owner try to make transfer. How other must confirm it? Which function of contract? Function "confirm" has parameter "h", but transaction of first owner is not work as value, transfer not complete (sorry for my English)
Alex Van de Sande
@alexvandesande
Contract wallet on the wallet client? Just click confirm?
delorule
@delorule
On the Mist. Second owner is other account in the same wallet. First owner confirmed by clicking. But there is no button for second owner confirmation
Alex Van de Sande
@alexvandesande
click the confirmed button again, it should allow you to select which account to approve it with
delorule
@delorule
There is buttons "Cancel" and "Send transaction" only. And field for password.
Alex Van de Sande
@alexvandesande
After a few minutes at most, a “confirmation pending” transaction should be at the top
delorule
@delorule
I'll try one more, thanks
delorule
@delorule
a “confirmation pending” transaction should be at the top
Nothing. Maybe the problem is both owners in one wallet? My ETH is freezing becuase of this experiment with second owner.

I have a fundamental doubt about DAOs and tokens, so lets say I have existing customer base and I provide some sort of a service/product. I want to give some value added service - so I could issue gift cards to them(or loyalty points scenario) now I could issue each token(which are coins) some value to ethers? So, I give 5 tokens in the giftcard or 5 tokens for 10 points, now where will the user exchange 5 tokens and get dollars or ethers or BTC?
I have a DAO which will automatically issue some tokens into the gift card or will send it to the user's wallet. How will the user redeem it?
Alex Van de Sande
@alexvandesande
@batteringram01 you can use ethereum to create tokens and gift cards, and you can use ether to fund them to real world value. But where that ether comes from and how you set up exchange rates it’s up to your dao
Sriram Kumar
@batteringram01

So let us look into a scenario, like I said I have 500 customers, now assuming they all have wallets and connected to ethereum.

Now I would write a simple token contract, a DAO, deploy it on the blockchain. Now the DAO will mint 5 tokens, send it to all the 500 customers.

  1. Now all the 500 customers will have 5 xyztokens issued by the contract(or dao) which will be in the contract.
  2. User can use the DAO address to check balance and also make a 5xyztoken to ether conversion and make the DAO transfer ethers to their wallet

Makes sense?

@alexvandesande
Alex Van de Sande
@alexvandesande
Yes, it makes sense.
Only thing would require more thought would be exactly how the dao prices the tokens, how it funds itself and how it protects itself from currency fluctuation. But that’s more business than programming
Sriram Kumar
@batteringram01
Now, the user at minimum will need the DAO address , that is all? But it requires some work on the wallet since ethereum wallet does not support that does it? I am talking from an enduser perspective.
@alexvandesande yeah true that.
Alex Van de Sande
@alexvandesande
Yes, it would require some work to make it easier for end users as ethereum frontend isn’t up to that level yet
Sriram Kumar
@batteringram01
right got it
delorule
@delorule
@alexvandesande Where can I find the answer to confirmation by second owner? There is no answer on slack.slock.it or forum.daohub.org
Rincker
@Rincker
Hi, can someone point me to where I can resolve the lost Ether I send to my account but never arrived?
Luca Zeug
@luclu
@Rincker did something like this happen to you? ethereum/mist#605
Rincker
@Rincker
@luclu Yes, its 30 hours since the transaction..The wallet says it doesn't show incoming transactions, but then how can I send the ether in the account?
Luca Zeug
@luclu
Could it be that you mixed testnet and mainnet addresses?
Rincker
@Rincker
The Ether must be on the main net, the wallet may be testnet, but the adress worked. Do I need to open a wallet for mainnet? I was wondering how that worked..
Luca Zeug
@luclu
you can only send ether within one network (main or test).
Rincker
@Rincker
Luca Zeug
@luclu
is you wallet on the main net?
Rincker
@Rincker
How do you tell the two apart?
