Finding Your Way with GpsDrive
GpsDrive is an excellent tool for displaying the positions of one or more GPS receivers in real time. It is suitable for several applications, from fun stuff like tracking a Sunday afternoon's exploration to serious work like search and rescue.

Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?

gpsdrive street level routing data
Wouldn't the files freely available at
http://roadmap.digitalomaha.net/maps/ provide an open source of street-level routine data?

Nice if you live in the US! Here you have to pay for those sort of maps.
http:/www.openstreetmap.org has a project running to produce free streetmap data & it needs gps tracks and people with local knowledge. Please take a look to see how all of us can help by working on where we live, work or visit.
How to load the nasa map?
I've read the README, but I can't seem to get the nasa satellite map to load. Maybe a bit of help from you (since you got it to work) would be valuable for people reading this article. These are the steps I took:
1. Downloaded MOD09A1.E.interpol.cyl.retouched.topo.3x21600x21600.gz
2. gunzipped it, and moved it to ~/.gpsdrive/nasamaps/top_nasamap_east.raw
3. Start gpsdrive, and "misc menu" -> "maps" -> "import map"
4. I've tried various combinations of coords and screen x/y values, but every time I "browse filename" during step 1, I get a "mapfile could not be loaded".
This is using gpsdrive 2.09 _without_ a gps receiver attached... just in simulation mode. Thanks in advance for any suggestions.

i want to get maps to study
This is APRS like.
Well, sort of. This is sort of APRS like. APRS is a ham radio "automatic position reporting system" that has been around for some time now (see www.aprs.net and for an interesting application: www.findu.com). In the bowles of the sites, you can find maps that may be compatable. The main feature aprs has that we don't have here, are that positions in APRS can be sent via ham radio, and there are other thing aprs will do such as 2 way messaging, and that arps is also suitable to aid in disaster situations. I am not saying that one is the better than the other, rather, both has had some good development and both systems may be able to benefit from the work already done on the other.
