Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma
You can get the list of supported formats with:
ffmpeg -formats
Convert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:

"""Python script to create a histogram of words in a text file. | |

Specify the path to the text file as above. Manually specify the top N words to report (default 100). | |
Text file can contain punctuation, new lines, etc., but special characters aren't handled well. |
In this article, I will share some of my experience on installing NVIDIA driver and CUDA on Linux OS. Here I mainly use Ubuntu as example. Comments for CentOS/Fedora are also provided as much as I can.
So one of the painful points of using docker
on OS X is that you need to run a virtualbox VM, which often suffers from performance issues. With xhyve, a OS X virtualization system, and docker-machine-xhyve you can now have docker
use the native OS X hypervisor to run containers.
No more dealing with virtualbox shenanigans!
In this script, I've also set up a way to autoconfigure terminal sessions to load docker's environment vars (dependent on docker-machine
) so you do not have to run eval $(docker-machine env whatever)
every time you open a new terminal window.
