I am pretty new to blockchain development and would like to know how I can get started. My idea would be an linux enviroment (proably ubuntu) with visual studio code.

I will use it mainly for qt wallets and will also checkout solidity. Is vs code suited for this or should I use another iDE?

Code:

I wanted to test out a segwit wallet on electrum, but when I broadcast a new transaction I get the this error.
[code]
error: {'code': 1, 'message': 'the transaction was rejected by network rules.\n\n16: bad-txns-vin-empty

Steps to reproduce
1. Create new segwit wallet with electrum
2. Send funds to an andress from this wallet
3. Send funds from this address

What does this error mean and how can I fix it?[/code]

I would like to query data with the CLI and parse the response. I am using the terminal with jq for this.

}

My goal is to change the unix timestamps to another format and pipe the result to another command.

So, the block time should be changed from this
  "blocktime": 1440604784,                                                                                                                           

to this
  "blocktime": "18.07.2018"

I noticed a a nasty bug on the electrum wallet. If you use it regularly and don't have any change addresses left, electrum will create new ones for you.

If you then restore the wallet from the seed, the newly generated addresses aren't visible / availalable anymore. How can I check the correct balance on my new wallet? Would it be possible to sign from the missing change addresses?

I have a staking wallet on a small VPS with a high amount of small inputs and would like to combine them. Due to the low hardware resources I am running only the wallet daemon without GUI. Is there an easy way to combine only the small inputs (I don't want to lose the weight of the larger inputs)?
