NSX on a VMWare Homelab with limited resources

I run a VMWare lab at home, because I have a forgiving wife and a tendency to over-complicate everything.

My VMUG Advantage subscription gives me a license for NSX, which is something I’ve been wanting to play with for a while.

Unfortunately, the resource requirements for a minimal installation of NSX is 16 vCPUs and 28GB RAM.
In my setup, this is a significant chunk of my resources, not leaving much for any actual VMs Continue reading NSX on a VMWare Homelab with limited resources

DNSMasq suddenly stopped working?

If you’ve recently done an update on your debian or ubuntu Linux system, and you’re running dnsmasq, you might have noticed that it’s no longer responding to remote queries.

It will now only answer to itself by default Continue reading DNSMasq suddenly stopped working?

wearPi – Stripping down the MyVu for an HMD

A few months back, I got my hands on a Raspberry Pi. As soon as i got it, I realised I didn’t have a use for it.

Then a week back, I had a pair of MyVu Solo’s. Sure, they’re not exactly the latest and greatest in Personal Media Viewers, but they would serve the purpose of displaying information.
The problem though, is (apart from looking ridiculous), they completely occluded my vision when I put them on.
So I’ve hacked them apart, and am in the process of turning them into a monocular display.

Here’s how I did it (and as far as I can tell, I’m the only person who didn’t destroy bits in the process)

HOWTO: Multicast Irish Freeview (Saorview)

If you’re in Ireland and you’ve been watching TV, you probably know about Saorview and the migration to Digital Terrestrial TV.

Being a geek, I decided that using a TV to view TV wasn’t really the way to do things.
So instead, I decided to find a way of viewing Saorview on my PC.

So the easy way, is to get a DVB-T receiver for a PC, and tune to the channel you want to view. I’m not going to show you how to do this, because the guys at mpeg4ireland already have.

I’m going to show you how to receive every Saorview channel at the same time.
Although I’m sure you’re not going to be able to watch them all at the same time…
