Passwordless ssh
The underlying technology used here is the public key encryption scheme.
1. Use ssh-keygen, specify the name of the file containing the key
2. Copy the contents of the generated public key to ~/.ssh/authorized_keys in remote host
3. In remote host, chmod 600 authorized_keys
4. Enjoy ssh without passwords!

teddyhartanto / build from source.txt
Created February 8, 2017 02:44
Building from source
1. sudo apt-get install build-essential
-> This will fetch all the common packages you need to build anything (e.g. the compiler etc.)
2. sudo apt-get build-dep python2.7
-> This will fetch all the libraries you need to build python.
3. wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz
tar -xf Python-2.7.13.tgz
-> Then download the source code for python and decompress it into a directory.
4. cd Python-2.7.13
5. ./configure
-> this check if you have the essential libraries needed to build the source (i.e. check if you're ready to build)
