Kilo Nova deploy recommendations

What would a Nova developer tell a deployer to think about before their first OpenStack install? This was the question I wanted to answer for my linux.conf.au OpenStack miniconf talk, and writing this essay seemed like a reasonable way to take the bullet point list of ideas we generated and turn it into something that was a cohesive story. Hopefully this essay is also useful to people who couldn't make the conference talk. Please understand that none of these are hard rules -- what I seek is for you to consider your options and make informed decisions. Its really up to you how you deploy Nova. Operating environment Consider what base OS you use for your hypervisor nodes if you're using Linux. I know that many environments have standardized on a given distribution, and that many have a preference for a long term supported release. However, Nova is at its most basic level a way of orchestrating tools packaged by your distribution via APIs. If those underlying tools are buggy, then your Nova experience will suffer as well. Sometimes we can work around known issues in older versions of our dependencies, but often those work-arounds are hard to implement (and…

This was a Canberra Bushwalking Club walk lead by John Evans. Not very long, but I would never have found this site without John's leadership, so much appreciated. [kml: 20150107]

I walked up to Wanniassa Trig this afternoon. It was a nice walk, the nature park is in the middle of suburban Canberra, but you couldn't tell that from within much of the park. The nature park also has excellently marked fire trails. There were really cool thunderstorms on the ranges as I walked, whilst I managed to avoid getting rained on while walking. [kml: 20150104-2]

Another day, another trig. This time with Doug, who got to play with his new radio at the top of the hill. [kml: 20141231]

I bought this book because of a review I saw online recently, and I have to say I loved it. Its interesting, humorous, and a generally fun read with a story line that I haven't seen before. Its refreshing to encounter a new author who has some genuinely new ideas to explore. I highly recommend this book.

Playing with alternate cameras: the GoPro Hero 3

I wasn’t happy with the behaviour of the kit lens on my Canon 650d when I shot the Christmas bottle stopper videos. I therefore decided to try out a few other cameras I had lying around before just going and buying a better lens for my Canon SLR. First off, I gave a GoPro Hero 3 a try.

A quick walk to Tuggeranong Trig

This one was a super quick walk on the way to the hardware store. As well as the trig point, there was a defunct radio repeater at the top of the hill -- I believe this one was for the old analog Police radio network. [kml: 20141230]

A walk around Mount Stranger

This is a walk around another hill a short drive from my house. The track was less well defined this time, so more bush bashing. There were these star pickets with white caps along the way which marked a join between two fire trails -- I think they indicate where fire trucks should go if they need to, but I am guessing. Bagged another trig point this walk as well. See more thumbnails [kml: 20141228]

I've been doing a lot more wood work recently, and I decided I wanted to write that up somewhere. Instead of posting it here, I also wanted to play with wordpress as an alternative hosting solution. The wood working is therefore being blogged on a new site, madebymikal.com. So far I've made a Thien Baffle cyclonic separator to stop my dust extractor filling with planer shavings, as well as documenting the process of making home made vanilla essence with turned bottle stoppers for Christmas. Oh, and I found a source of cheap high quality bar clamps in Australia. Not too bad for the week before Christmas I don't think.

Walk up Tuggeranong Hill

I've had a hankering to do a bush walk for an while, and so I spent some time yesterday walking up Tuggeranong Hill. This was a really nice walk -- the access road for the ACTEW substation provides parking with shade from trees, and its very very close to my house. The entrance to the fire access road for the broadcast repeater at the top the hill isn't well marked, so I ended up going the long way. I think this made the walk more fun to be honest.
