Alice, the Turtle of the Modern Age

Many of us grew up with LOGO, the kid-friendly programming language that guided a little turtle around a screen. Yes, it was simplistic. Yes, it taught only the very basics of programming concepts, but it also inspired an entire generation of programmers. The applications you run every day were written by people who steered a digital turtle around a screen in third grade.

Alice is a project from Carnegie Mellon University that allows new programmers to use a drag-and-drop interface to create 3-D scenes and perform programmatic results without typing any code. The Alice Project has evolved through the years, and it's currently on version 3. The code is freely downloadable and is available for Linux, Mac and Windows.

Although the LOGO programming language allowed for some lengthy instructions for the turtle, it was limited. Alice, on the other hand, uses the animation environment to teach amazingly complex programming concepts. By utilizing an environment where syntax is dragged as opposed to typed, it takes "typos" out of the equation. It's hard to describe just how complex the programming can be with Alice, so I urge you to download it or at least visit the Alice Project at http://www.alice.org.

For doing its part in producing the next generation of programmers, while (at least in my mind) continuing the legacy of a small digital turtle from my youth, Alice gets this month's Editors' Choice Award.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
