Open Source Software - Find, Evaluate, Collaborate - OStatic Introduction to the Command Line Commands enable you to do all sorts of powerful things. We will demonstrate this by looking at an everyday task you might be familiar with. If you use a digital camera, you probably have a folder full of images on your computer. Imagine you wish to resize the image profile.jpg so it is 300 pixels wide and then save it as a new image called profile_small.jpg. Using an image editing software, the steps you need to go through might be as follows: Open the image editor from the Applications menu. Using the command line, you can achieve the same result by typing the following: convert -resize 300 profile.jpg profile_small.jpg That is one step in the command line instead of eight steps using the image editor. A single command can do the same thing whether you have 30 images, 300, or 3000. Advantages of Using Commands Many people who give the command line a try are so amazed by its possibilities that they do not even want to go back to a Graphical User Interface(GUI)! The Value of Scripting

WEBI.ORG - Open Source Software & Free Software 4 Free Software alternatives to Matlab For those involved in data analysis, numerical computation and taks of that nature, Matlab is an industry standard software to use, though it is not necessarily the best available. The problem is that (Matlab) is commercial and can be expensive. Recently I took a class on Machine Learning and was surprised to find that the professor was not going to use Matlab, but a Free Software alternative called GNU Octave, which was good news because it meant not having to spend money on a proprietary software. Being relatively new to this field, I decided to see what other Free Software alternatives are available. The following list (in alphabetical order) contains four alternative to Matlab that I found: 1. GMT is officially described as a: General purpose calculator program similar in some aspects to BC, Matlab, Maple or Mathematica. 2. High-level interpreted language, primarily intended for numerical computations. 3. Sagemath’s user interface is described as: 4.

Les data en forme Tour d'horizon de la galaxie data. L'équipe des journalistes de données d'OWNI livre l'essence de sa veille hebdomadaire. Au programme cette semaine : data parlementaires, billets verts et hautes altitudes. Entre autres. Cette semaine, attaquons par du sérieux : parlons politique.
