Ansible get the username from the command line -

-
in playbooks reference username (exclusively "ubuntu") lot. is there built in way "get value passed in command line"? i know can do ansible-playbook <task> -u <user> -k --extra-vars "user=<user>" and can use {{user}} in playbook, feels odd defining user twice. as woodham stated, ansible variable represents connecting user is {{ ansible_user }} (ansible < 2.0 {{ ansible_ssh_user }} ) but don't have define in inventory file per se. you can define in: 1. play, if use ansible-playbook: see manual on playbooks - name: play hosts: remote_user: ubuntu 2. in inventory file: see manual on inventory [all] other1.example.com ansible_user=ubuntu (ansible < 2.0 ansible_ssh_user) 3. stated, on commandline: ansible-playbook -i inventory -u ubuntu playbook.yml 4. ansible config file remote_user directive. see manual on config file the ansible config file can placed in current folder ansi...

python - Why are Pickle files in Pickle protocol 4 twice as large as those in protocol 3 without having any gains in speed? -

-
i testing python 3.4, , noticed pickle module has new protocol. therefore, benchmark 2 protocols. def test1(): pickle3=open("pickle3","wb") in range(1000000): pickle.dump(i,pickle3,3) pickle3.close() pickle3=open("pickle3","rb") in range(1000000): pickle.load(pickle3) def test2(): pickle4=open("pickle4","wb") in range(1000000): pickle.dump(i, pickle4,4) pickle3.close() pickle4=open("pickle4","rb") in range(1000000): pickle.load(pickle4) test1 mark: 2000007 function calls in 6.473 seconds test2 mark: 2000007 function calls in 6.740 seconds protocol 4 slower protocol 3. kind of difference can ignored. however, hard disk usage different. pickle3 uses 7,868,672 bytes. pickle4 uses 16,868,672 bytes. that's no reason. continue dig out. after read pep3154 , understand protocol. for tuple(1,2,3,4,5,6,7) of protocol 3 ...
