NrvrCommander automation release

2014/01/07

What may matter most about the free and open source NrvrCommander: It is in actual use.

What it is

NrvrCommander makes virtual machines, and it controls them for automation.

NrvrCommander does at least some things other automation software doesn’t, or didn’t when we looked.

For example, in NrvrCommander’s example scripts the starting points are original OS distributions, from there on scripting, not requiring acceptance of pre-made VM snapshots. Your appreciation may depend on whom you trust and how many variations you need. In addition to transparency (review, audit) and flexibility (variations by coding a few lines), scripts take arguably 10-5 of the storage space of snapshots. This is not mandatory, not a limitation: You could start from snapshots, and one example script cleverly uses snapshots.

Aquifer Depletion in California’s Central Valley and Santa Clara Valley

2014/02/23

This is a summary of sources.

More than a century of data in USGS Circular 1182 Land Subsidence in the United States http://pubs.usgs.gov/circ/circ1182/ , specifically:

Those three files contain different information each. They are worth looking at each, all pages, even if you don’t read all details.

About 2013 activity in Stanislaus County, notable articles for numbers mentioned:

Hoping this compilation will help in coming to good decisions. It has been written preemptively, to supply science and history when discussions, as regrettably too common in contemporary politics, would become too sidetracked or partisan.

NrvrCommander documentation DIY

2014/01/08

NrvrCommander should have more documentation. Today I write why I don’t write more documentation today.

There is some good documentation already.

If we would wait for perfection, we would be withholding a working tool.

GUI on headless Linux server [SOLVED]

2013/09/27

I merely wanted to run NrvrCommander to do load testing with Selenium – a combo working quite well – but circumstances forced me to first regain control of a remote computer I had been driving just fine until one morning VNC stopped working. Presented is a documentation of working solutions, and how we got here.

The failure of VNC started with no clearly identifiable single cause. There have been multiple causes:

• Possibly one trigger of events has been a network reconfiguration at the site hosting that remote computer. Cannot be certain.

• Another trigger may have been a reboot behind that site’s KVM switch switched to a different computer and our computer not receiving EDID information – apparently a weakness of that specific KVM switch.

• Another problem has been a known issue with the operating system’s built-in vino-server storing the password differently in some versions under some circumstances, which wasn’t obvious at all, specifically if not seeing the remote screen.
