You'd think I know where I am when at home

Been mucking around with the ipodtouch having rescued it from the family for the last week. I have been subject to the "can't find your location" feature while at home. Google points me at Skyhook Wireless' site at GetSatisfaction and I discover that like Plazes, it uses a database solution, in this case run by Skyhook, who explain how it works on their site. This means that you need to be connected to the net to discover your location, but since that's true of the map application, its not too onerous a constraint.

For a 'touch, I need to find out my router's MAC address, which is harder than I'd like; it doesn't seem to display in the control panel. I was pointed at NetStumbler, but it has to run on an operating system it supports with wireless. NB this seems to exclude Vista 64 and obviously in retrospect my desktops, so on my third install I finally discover the address and use it to update SkyHook's database. I need my Longtitude and Latitude for this, which I have never bothered to record, so I used http://www.streetmap.co.uk to get this because its easy.

I had to wait ten days, but its working now.

And now I have a Centos VM

The reson for upgrading my Virtual BOx config is to install a Red Hat Centos image. I chose 4.7 because this seems jolly popular within the hosting community and I need a new host for my web servers. Two pieces of advice

  1. Download the x86 DVD image, I couldn't see how to use the multiple disk images with Virtual Box.
  2. It installs an SMP and uniprocessor version and grub is configured to start the SMP version as default. This thread, entitled CentOS 4.7 guest won't start, suggests that one should configure PAE/NX=on for the SMP image. This is not the default. Anyway works for me.

Now I need a manual to help through all those little differences between it and Ubuntu. Is been a couple of years since I played with Red Hat's Linux.

Virtual Box 2.2.4 & Windows XP

And with one might bound he was free..................

I downloaded Virtual Box 2.2.4 a couple of days ago, but when I tried to install it on my XP SP/3, the install process failed and rolled back. This trouble ticket, #3701 details how to fix the windows registry which was damaged at v2.2.0.

Thanks to those who helped me find it.
