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

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)
I have been using LDAP as a central data store for a very long time. Back when I had a home Asterisk PBX, I had an LDAP directory that functioned as a household phone book and source of caller-ID data for the IP phones installed through the home. This LDAP directory was also the authentication … Continue reading LDAP on z/VM as an Open Authentication Source
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
A week or so ago I succumbed to the hype (and the nagging from my devices) and installed iOS 8 on a second iPad. As far as updates go it was smooth although the post-install setup wizard crashed before it could ask me about things like iCloud Drive, which made me wonder whether I might … Continue reading iOS8 and OS X Yosemite
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
A little while back I did an "emerge system" on my VPS and didn't think much more about it. First time back to the box today to emerge something else, and was greeted with this: >>> Unpacking source... >>> Unpacking traceroute-2.0.15.tar.gz to /var/tmp/portage/net-analyzer/traceroute-2.0.15/work touch: setting times of `/var/tmp/portage/net-analyzer/traceroute-2.0.15/.unpacked': No such file or directory ...and the … Continue reading Another round of Gentoo fun
With Apple's abandonment of PPC as of Snow Leopard, I began wondering what to do with the old PowerMac. It's annoying that so (comparatively) recent a piece of equipment should be given up by its manufacturer, but that's a rant for another day. Yes, we can still run Leopard until it goes out of support, … Continue reading ppc Linux on the PowerMac G5
I've been trying to solve a problem at work for a few weeks now -- one of those tricky "it's only software so it shouldn't be this hard" sort-of problems for which you know the solution is just a matter of putting the right bits and pieces together. At work, I'm more-or-less forced into using … Continue reading Are we letting Microsoft define our industry?
It's all the rage on YouTube, apparently... posting video of a z/VM system booting something. Only kidding, this is a good piece of tech. If you search YouTube for "OpenSolaris System z" you'll find a set of five videos that show an interview (recorded at the recent Gartner datacentre conference) with David Boyes of Sine Nomine Associates demonstrating … Continue reading OpenSolaris on System z
