Public Art with Augmented Reality and Blender
Augmented reality artist/developer, Nathan Shafer, has plans to illustrate the history of Exit Glacier in Seward, Alaska via 3D modeling using popular open source modeling software, Blender. The finished result will allow young scientists, school children, and other visitors to use mobile devices equipped with Shafer’s app to view reconstructions of the 5 former termini that were present before the significant, visible shrinkage that illustrates the larger issue of glacial recession.
In Shafer’s words:
I make digital pieces and upload them into the real world. I am modeling in Blender, because it has proven to be the most dynamic and efficient 3D program for what I do. In AR the name of the game is efficiency. 5000 polygons is about the max for any model in a browser. I am building some models that are literally 3 miles long, so I have to condense. I am using geodata provided by Kenai Fjords National Park to generate NURBS that will approximate the height of the glacier, sort of give me a box to work in. The look of the glacier is being rendered using a mix of plug-ins and lightning effects, which oddly enough never look the way you want them to when they translate into an AR browser and get the real world all around them. The model is being skinned with actual photos of the glacier using the node-based compositor and textures, after that is done, we want a scanline rendering that runs an algorithm calculating the actual sun over the virtual model (hopefully in real time, which is very hard).
Shafer is using Kickstarter, the popular fundraising site to fund his project, and you can read more about it there.

Practical Task Scheduling Deployment
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
