Lightspeed on Your Desktop
You can change the dimensions of the default cube object by selecting the menu option File→New lattice (Figure 2). You can set how many balls will be drawn in each of the three dimensions. You also can change the smoothness factor when the object is rendered on the display. In this case, it will look like what is shown in Figure 3.

You also have the option of loading your own 3-D object, either in 3D Studio format (*.3DS or *.PRJ) or in LightWave format (*.LWO). This new object is what will be rendered, and the optical effects will be applied to this. You can save a snapshot of a particular object at a particular speed in either PNG or TIFF format. You also can export to an SRS file format (Special Relativity Scene). This is a format used by the program BACKLIGHT, which is a specialized raytracer used to illustrate relativistic effects. This lets you generate much higher resolution images of the affected object.
In the Objects menu item, there are options for drawing supplementary objects. By default, the floating grid is selected. You also can select coordinate axes, identifying the x, y and z axes. You can select the display of a bounding box for your object as well (Figure 4).

Additionally, you can animate the scene by selecting Objects→Animation in the menu. This pops up a dialog box where you can select the starting and ending points on the x axis and the loop time in seconds (Figure 5). The scene then will be animated until you click stop.

Getting Started with DevOps - Including New Data on IT Performance from Puppet Labs 2015 State of DevOps Report

DevOps represents a profound change from the way most IT departments have traditionally worked: from siloed teams and high-anxiety releases to everyone collaborating on uneventful and more frequent releases of higher-quality code. It doesn't matter how large or small an organization is, or even whether it's historically slow moving or risk averse — there are ways to adopt DevOps sanely, and get measurable results in just weeks.
