I’m happy to learn that Asterisk 1.4 is out.

While working on some Xen stuff, I’ve found that a drawing is about the easiest way to document some things.

I’m going to be doing some drawings of custom Xen networks, but until then, here are a few drawings of default Xen networks to serve as a point of reference.

This first one just shows how a non-Xen networking setup might look. The white box is just a label. Not much to see :)

Now, we’ll look at what starting xend does to our network. Later on, I’ll try to blog about the scripts that make this change and how they work. If you boot into your Xen kernel in and haven’t done anything with Xen yet, this is what your setup looks like (well, maybe).

If you bring up a guest OS (DomU), this is what your networking will look like. This set-up is suitable for most Xen installs.

More to come…

Update: Changed the X in vifX.Y to match the domain ID. Good eye Lamont.

Christer Edwards pointed me to the best bug report I’ve ever seen:

Microsoft has a majority market share in the new desktop PC marketplace.
This is a bug, which Ubuntu is designed to fix

Microsoft has a majority market share | Non-free software is holding back innovation in the IT industry, restricting access to IT to a small part of the world’s population and limiting the ability of software developers to reach their full potential, globally. This bug is widely evident in the PC industry.

Steps to repeat:
1. Visit a local PC store.
What happens:
2. Observe that a majority of PC’s for sale have non-free software pre-installed
3. Observe very few PC’s with Ubuntu and free software pre-installed

What should happen:
1. A majority of the PC’s for sale should include only free software like Ubuntu
2. Ubuntu should be marketed in a way such that its amazing features and benefits would be apparent and known by all.
3. The system shall become more and more user friendly as time passes.

Good work Ubuntu! Now, get that bug closed; it’s a blocker!

This should lead to some interesting search results. If so, I’ll share what I’ve learned 5 or 6 weeks from now.
