Roll your own Unix or something similar

I came across this very interesting tutorial by James Molloy on how to roll your own Unix like clone, with nice, detailed, step by step instructions.  It assumes your development environment is going to be a GNU/Linux environment.

It's aimed at developing a *nix like operating system on x86 architecture.  All the way through setting up a development environment, boot loader, interacting with the screen, dealing with interrupts and the timer, user mode, etc.

This tutorial can be used as a guide for creating any operating system, or simply boot programs, for x86 and x86-like architecture, for example the RDC CPUs used on devices like the Bifferboard.

Introduction to VMWare vCenter Operations

I'm busy looking at VMWare vCenter Operations Enterprise.  I've never dealt with it before so it could be interesting.  I'm going to give an overview of what this product is, where it comes from, and what it tries to achieve.  I'll also give some first impressions as a user of it.

It appears that VMWare bought a lot of products in order to give their customers various comprehensive IT management capabilities for their software and platforms.  Like with most big vendors buying other software products and integrating it with their own offering, I expect some quirks with the integration.

VMWare vCenter Operations started life as a product called Alive by Integrien.  Integrien was acquired by VMWare around August 2010, so VMWare has had some time to assimilate the product to make it their own.  vCenter Operations comes in a few different sizes, Standard, Advance and Enterprise:
The smallest is Standard which handles up to 1500 vSphere deployments, so it's not that small…
