IBM RedWiki on IBM Director

IBM Systems DirectorIBM Director and the IBM Systems Director play an important roll in the future of managing IBM Servers and especially IBM System p. I’ve been a long term fan of the IBM Redbooks, and have written three myself, and co-authored or been a contributor to five or six others.

So, it was with some delight that I learned today they Redbooks people are trying a new idea. They are going to build a wiki on IBM Director. It’s an excellent idea, and you’ve done any extensive work with IBM Director, or if you are an IBMer in ITS or S&D who wants to learn more about Director and use the opportunity to create some real value, perhaps you might take part in an ITSO Residency to kick start the wiki!

Old friends – Assembley language and architecture

It has been a very long time since I did any serious coding, even longer since I coded in Assembler. However, one of the things I wanted to understand was a little about the basic machine architecture. Of course the best way to start on the architecture is by understanding the Assembler language.

I didn’t really need to learn how to program over from scratch, and after poking around came up with another couple of excellent Developerworks resources.

First is the Linux on Power wiki – A great effort that seems to include answers to most questions about running Linux on Power, and really good introduction to the Power 5 architecture. Next, is a 2-part write-up on the Assembly Language for Power by  Jonathan Bartlett a Director and lead developer at New Medio.

Even better, I found that Bartletts “Programming from the ground up” on Assembler programming for Linux is available as a free download in pdf format. So that was interesting set of discoveries, for me at least.
