The first part introduced my Raspberry Pi tower and some of the progress I’ve made in interfacing with OLED and LCD devices over I2C. Now, I’m going to talk about some of the infrastructure software used in the system. Gentoo Linux Firstly, as I introduced previously, I’m using Gentoo Linux as the base OS layer … Continue reading Raspberry Pi adventures, Part Two

Part One of my Raspberry Pi adventures (so far)
A DIY task leads to reflections on the tools we use.
I was introduced to the z/VM hypervisor in the early 2000s, around the time that IBM announced formal support for Linux on the System/390 family (earlier in my career I had heard of something called "VM/ESA", and thought it sounded cool). I was part of the team that wrote the "ISP/ASP Solutions" IBM Redbooks publication, … Continue reading z/VM Express System Installation (ESI)
It's been a long time since I wrote here. The earlier content you see here actually came from my previous blogs at veejoe-dot-com-dot-au and later viccross-dot-com, both of which for various reasons are... no longer available. So why relaunch? Well, mostly because I still have things to say! I have not decided exactly what yet, … Continue reading Relaunching… again
My Linux-based Large-Scale Cloning Grid experiment, which I've implemented four times now (don't ask, unless you are ready for a few looooooong stories), has three main components to it. The first, which provides the magic by which the experiment can even exist, is the z Systems hypervisor z/VM. The second is the grist on the … Continue reading Programming decisions
It's easy to treat a silly slogan on a coffee mug as little more than just a few words designed to evoke a wry grin from a slightly antisocial co-worker. Sometimes it can take on a deeper meaning, if you let it.
Ever since work issued me a Lenovo T61 and I installed Fedora on it, I have lamented the loss of something that X afficionados referred to as "Zaphod mode". By gluing together a few different software and hardware components I managed to get close to the old Zaphod mode days -- but first some background... … Continue reading DisplayLink and x2x brings back Zaphod mode
Earlier this year (30 March, to be precise) Oracle announced that Oracle Database 11gR2 was available as a fully-supported product for Linux on IBM System z. A while before that they had announced E-Business Suite as available for Linux on System z, but at the time the database behind it had to be 10g. Shortly after 30 … Continue reading Oracle Database 11gR2 on Linux on System z
The next phase in tidying up my user authentication environment in the lab was to enable SSL/TLS on the z/VM LDAP server I use for my Linux authentication (I'll discuss the process on the DeveloperWorks blog, and put a link here). Apart from being the right way to do things, LDAP authentication appears to require SSL or TLS in … Continue reading What a difference a working resolver makes
