This is the story of Helmer. A linux cluster in a IKEA Helmer cabinet.

Phew, PowerTime is now munching 16 million readings of European precipitation data at last. The images were generated using the PowerShell integration. The graphs consist of rolling 365 day averages. The test run takes 1,365.78 seconds (around about 22 minutes.) Whilst that’s not going to break any speed records, it isn’t as slow as I [...]

[The title is a Human League song reference: The Black Hit of Space]
Apologies for the light posting regime at the moment. As ever programming sucks all of the time out of my day. There’s no middle ground with programming, no negotiation, you’re either not programming or you spend all of your time programming to the [...]

I’ve written about my woes finding some good test data sets for PowerTime before…some good news. There is a place you can get hold of climate data for free over at European Climate Assessment & Dataset project. Whilst the temperature data is averaged, the precipitation data is not…so that’s what I’m going to use for [...]

Brian Boyko over at Network Performance Daily mentioned in passing that Network Instruments now have a blog.
Well worth a read… oh, and Network Performance Daily is well worth a read too!

I thought I’d provide a small taster of what you can expect to find in the PowerShell support for PowerTime.
PowerShell includes the ability to treat various resources as if they are akin to a file system. We figured that this would be an interesting way to deal with a time series database.
New-PSDrive -Name ptdb -Root [...]

Well, technically it’s afternoon but the reference to Whoops Apocalypse wouldn’t have worked otherwise.

The tests for PowerTime have been green before, but the tests and therefore the functionality, have now progressed a lot further. There’s still plenty of way to go…but at least we’re getting closer. Things have progressed far enough to allow Dean [...]

Almost as a doodle I thought I’d create a graph depicting the dependencies between a selection of open source network management projects.
Once I’d done it, it occurred to me how much just about everything depends on just a couple of projects or project variants of, RRDTool & Net-SNMP.

The main conclusion I draw from the [...]

A couple of months ago or so I lamented the fact that the raw temperature data from the UK met office is not publicly available.
I’ve just received some further feedback from the Met Office.
I was partially wrong, there is a lot more information available than I thought. Here’s a quote with a list of resources:

There [...]
