putting HTML codes and other special characters into a blog entry

I often want to write blog posts about HTML code and about source code in various languages. One problem I have is that the characters I want to use have special meanings (EG < and >), another is that I indent source code to make it readable and I don’t want the spaces trimmed from […]

configuring a Heartbeat service

In my last post about Heartbeat I gave an example of a script to start and stop a cluster service. In that post I omitted to mention that the script goes in the directory /usr/lib/ocf/resource.d/heartbeat.

To actually use the script you need to write some XML configuration to tell Heartbeat which parameters should be passed […]

Heartbeat service scripts

Another Heartbeat 2.0 STONITH example configuration

In a Heartbeat cluster installation it may not be possible to have one STONITH device be used to reboot all nodes. To support this it is possible to have multiple STONITH devices configured that will each be used to reboot different nodes in the cluster. In the following code section there is an example of […]

Does Paypal still suck? If so are there any other better options? The merchantinc.com recommended by paypalsucks.com seems to only cater for […]

New Blogs

After reading advice from ProBlogger I have become convinced that I should create separate blogs for some of the content that is currently on my blog. The first such blog that I will create will be about computer security. Naturally it will cover SE Linux to some degree, but the exact focus is something I […]

SE Linux in Debian

I have now got a Debian Xen domU running the strict SE Linux policy that can boot in enforcing mode. I expect that tomorrow I will have it working with full functionality and that I will be able to run another SE Linux Play Machine in the near future.

After getting the strict policy working […]

PC prices drop again!

A few weeks ago Dell advertised new laptops for $849AU, this was a significant development but I didn’t get around to blogging about it. Now I have just discovered that they have a special deal for $799AU for a laptop including delivery! This is an amazing deal and gives you an AMD Sempron 3500 CPU […]
