KVM, HortonWorks and IBM Spectrum Scale

IBM Spectrum Scale (former GPFS) is a clustered file system giving single access point to distributed parallel nodes. HDP is Hadoop implementation created and supported by HortonWorks. Both work together smoothly, GPFS can replace HDFS in a transparent way.
If you are entitled to use IBM Spectrum Scale, it is tempting to install IBM Spectrum Scale locally and explore its capabilities without setting up huge infrastructure.
Unfortunately, although there is plenty of ample information available, it is not easy to make the first step and just install it.
So I decided to fill the gap and install HDP HortonWorks on the top of IBM Spectrum Scale (GPFS) using KVM virtualization. I'm not paying too much attention to stuff like tunning, mirroring, replication, configuration etc. Just install using a default setting as much as possible to give the first taste of this fantastic feature.

Before you start:

• Make sure you are entitled to use IBM Spectrum Scale that way, review license agreement. IBM Spectrum Scale is not publicly available.
• Do not start unless you at least 32GB memory, otherwise, 4 KVM with at least 6 GB memory will kill your machine.

Civilization The Board Game, next version

Introduction
I deployed a new version of my computer implementation of  Civilization The Board Game. The implementation consists of three parts:

• Civilization Engine 
• Civilization Web Interface
• Demo. Demo version is deployed to Heroku, free quota. Please wait several minutes unless the dyno is brought back to life.

New features

• "Pottery" technology is enabled and you can gain coins by spending resources on them.
• Economy progress is scored.

Pottery and economy

"Pottery" technology is the first to be enabled so far.

When technology is researched and you have at least two resources hoarded you have the opportunity to transform wheat or incense into gleaming gold.

• "Use Technology" 
• Choose technology you want to use, here Pottery only
• Point the city where the action will be performed
• Select two resources to spend

After spending resources you will be two resources lighter but one gold coin heavier.

Also "Pottery" card weights one coin now.

Although you can collect coins, the economic victory is not implemented yet.
Next step

• Score culture progress.
