@PntA2B_twitter you need to install ethereum wallet on Ubuntu and not Debian to start with. Second: check the size of your Json file. Is it empty? (Try to cat it). Is the extension file correct?

@kuldeep-agg
May i know the difference bettween ethereumjs-library and web3.js
Bob Summerwill
@bobsummerwill
Hey @kuldeep-agg, ethereumjs-lib is an implementation of the EVM written in Javascript. So it is RUNNING a node. web3.js is a JS library for talking to a node over JSON-RPC. It can talk to any compliant node, whatever language they are written in. web3.js is usually what you use to join the front-end of your DAPP with the back-end (the blockchain).

Hello, I am new, I want to know where can I go to learn how to write a contract and code samples etc.. thanks a million.
@alexvandesande Please direct to where can I start learning about writing a contract and some samples of codes, thanks.

@alexvandesande
@marwanfarah in which page are you on right now? Have you tried ethereum.org?
@alexvandesande@bobsummerwill thanks a million. I went through ethereum.org, I could get lost before finding code. I am at readthedocs it seems that I have a lot of material to go through. perfect, thanks again.
Alex Van de Sande
@alexvandesande
@marwanfarah you can also try ethereum.org/token or one of the specific pages. Have a blast at it ;-)

Hello again :) Can anyone explain why my transactions fail to get confirmed? I can't transfer ether to my wallet. Transactions just appear, hang some time unconfirmed and disappear and nothing changes.

Hello, I'm trying to complete the greeter example on https://www.ethereum.org/greeter . I'm stuck at trying to deploy my contract using geth. Do you need to have your account unlocked to call somecontract.new([constructorParam], {from: accountAddress, ...], ...) to deploy a contract? Nothing happens when I'm trying to deploy my contract. I'm guessing it cannot take funds from my locked account and it does not ask me to unlock it.
@keuge it’s mint. As in Central Mint, the place that creates coins out of thin air. Mining is a specific name for rewarding in cryptocurrency in exchange of network security
keuge
@keuge
contract MyToken { uint256 public totalSupply;
function MyToken(...) {
totalSupply = initialSupply;
...
}
...
}
Alex Van de Sande
@alexvandesande
@keuge what is the question?
keuge
@keuge
what is this? where do i need to implement? why is it ..., instead of info?
_
Alex Van de Sande
@alexvandesande
Not sure I understand the question
This is called the constructor function
keuge
@keuge
"..." represent what?
First we need to add a variable to store the totalSupply and assign it in our constructor function. and then this code is ongoing. Its from here - https://ethereum.org/token#central-mint
i dont understant what do i need to paste to contract
Alex Van de Sande
@alexvandesande
Ah.. It represents the rest of the contract
Compare it to the original token contract and you’ll see where to add this

Hi all, i have a big problem. I have create a contract from this site: http://chriseth.github.io/browser-solidity/?#gist=21935dc37c5bfbe92e5a and with 8.65 ethers from my admin wallet. So the contract is failed because not enough GAS but my ethers away for that contract. i don't know how i get back my ethers!?
Alex Van de Sande
@alexvandesande
@samsa90 why did you send 8.65 ethers to a token contract?
samsa90
@samsa90
don't ask me :) in "my own contracts" is the contract with the ethers but i can't delete it and get the ethers back to my admin account
Alex Van de Sande
@alexvandesande
That is true, you can’t delete contracts from the blockchain and you can’t get it back once you sent it
So that ether is probably lost now. I recommend you do testing with test ether, so you won’t risk real money
samsa90
@samsa90
the process from the contract creating...
from which account
how much ether
than you can insert some code and that is what i do.. the code from this link from below
Alex Van de Sande
@alexvandesande
Yes. That is the right process. But you don’t need to send ether for a contract, the fee will be added later.
samsa90
@samsa90
and the transaction is not "created"... the transaction doesn't successful create because not enough GAS... i don't understand this logic.. i have a contract but the transaction doesn't successful :/
Alex Van de Sande
@alexvandesande
Did you move the gas fee slider?
samsa90
@samsa90
gas fee slider?

i can't see it at the moment when i click to the transaction
