I’m off to Kiwicon V this coming weekend.

If you’re interested in computer security and haven’t got a ticket, I suggest you make some very last minute plans to get to Wellington for the 5th and 6th November.

My brother recently got married and as per the rules of engagement, the lead up to the event included a Stag night.

For my Stag night, I was given a hard hat complete with a flashing LED light and plastic antlers.

I decided I wanted to make something special for my brother. Something minimalistic, but effective.

The result was this…..

This is a GlobalSat DG-100

It’s an amazing piece of Kit, but the software that comes with it is absolutely rubbish.

You can download all of the routes (and delete them from the unit) in one simple command with gpsbabel.

gpsbabel -t -i dg-100,erase -o gpx /dev/ttyUSB0 outputfile2.gpx

You’ll still need to set up the times/distance for recording for the switch positions A,B & C. I have mine set to 1,5 and 10 seconds. Easiest way to set these up is on a windows machine with DG Manager.

To combine two images of the same size with ImageMagick, you simply do the following:

The following will overlay overlay.png on top of output.png

mogrify -draw "image SrcOver 0,0 0,0 'overlay.png'" output.png

convert input.png -draw "image SrcOver 0,0 0,0 'overlay.png'" output.png

I’ve been doing some performance tests on WordPress to see how much of a difference the WordPress Super Cache plugin made.

It turns out that the plugin makes a huge difference. (more…)

I’ve taken the plunge, and this time I’m not doing it by halves.

I’m moving from my Windows Server 2003 physical co-located server to a Virtual Private Server (VPS) running Linux.

All of the websites have been transferred across, everything else is still to be moved over.

In the meantime, if you find any problems, or anything 404′s, please flick me an email at b…@john.geek.nz

I’ve recently come across the open source software Xplanet, which will render images of the globe with very realistic results.

I render them in 512×256, 1024×512, 2048×1024 and 4096×2048 resolutions. The clouds information is obtained from weather satellites and is typically around three hours old.

I also use monthly map files so that the snow/ice on the planet is more realistic.

Check out my real time renders at http://www.john.geek.nz/earth/.
