Gidday,
Are you using ext4 for production system? Or is it better to opt for a more
conservative strategy, like ext3 for instance?
What are your experiences?
Thanks in advance,
Loïc. (3 Replies)
Hi All,
I have written a script which does some editing in the files, based on user input.This might not be the most elegant way of doing it and there would be many improvements needed.
Please go through it and let me know how it could be improved.
Suggestions are welcome!!
Thanks!... (2 Replies)

getting started - numm installation and usage
SYNOPSIS
numm-run FILE
import numm
DESCRIPTION
numm is a python library -- the bastard child of Processing.org and MATLAB, if you will -- that fuses python, numpy, and gstreamer together
to create a numerical-computing environment for multimedia generation, analysis, and interaction.
Installation
A Debian package is provided for ease of installation on Debian and derivative operating systems, such as Ubuntu; we recommend you abandon
alternative systems and install Debian, but in the interim direct your attention to virtualization software such as VirtualBox.
The following command downloads and installs numm:
% wget http://numm.org/numm/releases/python-numm_0.1-1_all.deb
% sudo dpkg -i python-numm_0.1-1_all.deb
Usage
At its simplest, numm provides three pairs of invertable functions that connect common media formats with numpy:
Images represented as (height, width, color) numpy.uint8 arrays.
o image2np(path) -> np
o np2image(np, path)
Sounds as (frames, channels) numpy.int16s
o sound2np(path) -> np
o np2sound(np, path) # XXX: must be .wav
Videos as (frames, height, width, color) numpy.uint8s
o video2np(path) -> np
o np2video(np, path) # XXX: must be .mkv
For rapid-prototyping of interactive numpy-based audio-visual experiments, the numm package has a real-time mode. The numm package
installs a program named numm-run, which launches (and reloads on modification) python scripts that may implement any subset of the follow-
ing functions, which are asynchronously called as needed:
o video_in(a) # webcam
o video_out(a) # mutate a in-place to set video
o audio_in(a) # mic
o audio_out(a) # mutate a for audio output
o mouse_in(type, px, py, button)
o keyboard_in(type, key)
