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)!

3 Easy Ways Anyone Can Learn to Code We live in a digital world, yet far too many people, even millennials, are technologically illiterate. In a world where our smartphones are the first thing many of us touch in the morning and the last thing we touch at night, we need to be honest about the importance of technology, and, consequently, the role basic technical literacy plays in our world today. Jason Nazar encourages millennials to learn code, saying, “If you plan to stay gainfully employed, you better complement that humanities degree with some applicable technical chops.” To those hesitant to make this move, Ian Kinsey, the CEO of Semiformal Studios, which produces the MMORTS RPG game Ensemble, advises that “all it takes is a few days of learning the basics, a few days of figuring out how to get stuff to work, and then a lifetime of just building stuff that you don't know how to build, which is assisted through dedication and feverish googling.” How do you learn this?

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.
