Starting a Heartbeat Resource Without Heartbeat

The command crm_resource allows you to do basic editing of resources in the Heartbeat configuration database. But sometimes you need to do different things and the tool xmlstarlet is a good option.

The below script can be used for testing Heartbeat OCF resource scripts. It uses the Heartbeat management program cibadmin to get the XML […]

Xen Saves

A couple of days ago the hardware that is used to host this blog was upgraded – doubling the amount of RAM in the machine. To do this the machine was halted, memtest86+ was run to ensure that the new RAM worked correctly, and then it was booted up again. During that process my ssh […]

Advogato and Hateful/Divisive Posts

Firstly for the benefit of people who haven’t heard of it, the Advogato FAQ and the Wikipedia Page describe what Advogato does.

Pete Zaitcev posted a strange article about me to Advogato. In it he accused me of “pumping hateful leftist propaganda into Advogato“, said propaganda being my regular blog posts. In an addendum he […]

ECC RAM in a Cheap Machine

In a comment on my previous post about ECC RAM someone commented that Dell sells PowerEdge desktop machines with ECC RAM. I visited the Dell web site and found that a low-end PowerEdge tower server (which still has a Pentium-D dual-core 64bit CPU) costs as little as $800AU. I also noticed that Dell Precision workstations […]

Germany Leads the World in Solar Power

boston.com reports that Germany now has 55% of the world’s photo-Voltaic (PV) power generation.

The German solar power industry has created tens of thousands of jobs including significant exports – so much for the Australian government claims that supporting the dirty coal industry is necessary for the economy! The renewable power industry in Germany employs […]

Praising Children vs Praising Programmers

In a comment on my blog post titled Childhood, Don Marti refers to an earlier blog post he wrote which refers to a New York Magazine article about the effects of praising children. The article does in some depth to describe scientific research into the issue of praising children for being “smart” vs praising them […]

Hot Water

A response to a post I wrote about things to do for the environment suggested that there would be a health risk to lowering the temperature of a home hot-water system to save power.

I have just been reading about so-called tankless hot-water systems. The concept is that instead of keeping a tank of water […]

Porn vs Rape

Chris Samuel blogs about a plan to censor porn from the Internet in Australia. According to the ZDNet article the Fundamentalist Christian party Family First wants a national porn filter to protect children.

However there is strong evidence to suggest that the incidence of rape decreases as the availability of pornography increases. Access to porn […]

Blogs and Conversation (or Lack Therof)

I recently received an email from RSA inviting me to read their blog (after having requested an evaluation copy of one of their products). They invited me to “join the conversation“. Often blogs are described as a “conversation” and I’ve been considering whether that analogy is appropriate.

The Collaborative International Dictionary of English v.0.48 has […]

A Worse Visual Migraine

Last night I had a Visual Migraine that was significantly worse than the previous ones. It started in the usual manner (flickering lights in my central vision and an inability to read text on a computer screen in a font that is normally quite readable) but then developed a new feature. Grey clouds appeared in […]
