Open-Source Space

 in

As I write this, NASA has just passed another milestone in releasing its work to the Open Source community. A press release came out announcing the release on April 10, 2014, of a new catalog of NASA software that is available as open source. This new catalog includes both older software that was previously available, along with new software being released for the first time. The kinds of items available include project management systems, design tools, data handling and image processing. In this article, I take a quick look at some of the cool code available.

The main Web site is at http://technology.nasa.gov. This main page is a central portal for accessing all of the technology available to be transferred to the public. This includes patents, as well as software.

As a quick start, there is a subject cloud in the lower central region of the page that can do a search on several different keywords for you. Unfortunately, this is only a catalog of all the offerings, and it's not quite complete yet in terms of detailed information. So, for example, if you click on Command Control, you will be taken to a results page that includes items like Rendezvous and Proximity Operations Program (RPOP). If you click on that, you will be taken to a details page that is essentially unpopulated. The assumption is that this will be filled in as time allows in the future. It does give you a list of what is available though, which is half the battle.

Staying on the result list page, you should notice that there is the name of a NASA center on the right-hand side of each line. This is the actual source for the given patent or software entry. Once you find something of interest, you can go to the individual center's Web site to find more details about it. On the lower-right section of the main page of the NASA technology site, you can find direct links to the technology sections for each of the individual centers. The amount of information available at each of these centers varies, but you should be able to find out more details. Some of the sites have direct download links, so you can get the software that interests you. In other cases, sites provide only the contact details for a person you'll need to talk to in order to get copies of the software in question. A PDF catalog also is available on the front page of the main technology site. Here, you can get a 172-page catalog of all of the available software, broken down into 15 categories, for off-line access.

One issue that will become evident right away is that not everyone can access all of the available software. Some of the released software is available only to US residents, and some is even more restricted to only parts of the US government. So, is there an easier option for the international community? On the front page, there is a set of other useful NASA links on the lower-left side. The one labeled NASA Open Source Software (http://code.nasa.gov) will take you to a sister site that provides access to a more centralized repository of software released as open source. It is laid out as a list of available code within a WordPress blog, and it looks like it's being updated regularly. So, it's worth keeping an eye on this site for future releases.

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.
