// The new assembly support in Solidity makes writing helpers easy.
// Many have complained how complex it is to use `ecrecover`, especially in conjunction
// with the `eth_sign` RPC call. Here is a helper, which makes that a matter of a single call.
//
// Sample input parameters:
// (with v=0)
// "0x47173285a8d7341e5e972fc677286384f802f8ef42a5ec5f03bbfa254cb01fad",

The new 1.10 version of hdf5 library is stable. You can now install from the source to use this new capability.

The installation process has a few caveats, so here is how to do it.

Note:

1. you need to first remove the hdf5 libraries currently installed in ubuntu.
2. Then you need to reinstall h5py.
3. when you reinstall h5py via pip, use the --no-binary flag. This is because the h5py wheel comes with its own hdf5 binary.

Instructions:

#remove old
sudo apt-get remove docker docker-engine docker.io

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable"
