Speed up rsync over lan or wan with this simple addition to your command.

-e "ssh -T -c aes128-ctr -o Compression=no -x"

Her we use the new command in a safe (dry run) example

Run Python with Forever

By | Linux | No Comments

It is easy to use Python with forever.js:


forever start -c python


To use it with virtualenv is a little bit more complicated, I did it using a bash script (call it python_virtualenv):


# Script to run a Python file using the local virtualenv
source bin/activate
bin/python $@


Now use that script with forever:


forever start -c ./python_virtualenv
