city2surf 2018 wrap up

city2surf 2018 was yesterday, so how did the race go? First off, thanks to everyone who helped out with my fund raising for the Black Dog Institute -- you raised nearly $2,000 AUD for this important charity, which is very impressive. Thanks for everyone's support! city2surf is 14kms, with 166 meters of vertical elevation gain. For the second year running I was in the green start group, which is for people who have previously finished the event in less than 90 minutes. There is one start group before this, red, which is for people who can finish in less than 70 minutes. In reality I think its unlikely that I'll ever make it to red -- it would require me to shave about 30 seconds per kilometre off my time to just scrape in, and I think that would be hard to do. Training for city2surf last year I tore my right achilles, so I was pretty much starting from scratch for this years event -- at the start of the year I could run about 50 meters before I had issues. Luckily I was referred to an excellent physiotherapist who has helped me build back up safely -- I…

Dear humans of the Internet -- there is ONE WEEK LEFT to propose talks for linux.conf.au 2019. LCA is one of the world's best open source conferences, and we'd love to hear you speak! Unsure what to propose? Not sure if your talk is what the conference would normally take? Just want a chat? You're welcome to reach out to papers-chair@linux.org.au to talk things through. https://linux.conf.au/call-for-papers/

Rejected talk proposal: Design at scale: OpenStack versus Kubernetes

Post category:Conference OpenStack Python

This proposal was submitted for pyconau 2018. It wasn’t accepted, but given I’d put the effort into writing up the proposal I’ll post it here in case its useful some other time. The oblique references to OpensStack are because pycon had an “anonymous” review system in 2018, and I was avoiding saying things which directly identified me as the author.

OpenStack and Kubernetes solve very similar problems. Yet they approach those problems in very different ways. What can we learn from the different approaches taken? The differences aren’t just technical though, there are some interesting social differences too. (more…)

Accepted talk proposal: Learning from the mistakes that even big projects make

This proposal was submitted for pyconau 2018. It was accepted, but hasn’t been presented yet. The oblique references to OpensStack are because pycon had an “anonymous” review system in 2018, and I was avoiding saying things which directly identified me as the author.

Since 2011, I’ve worked on a large Open Source project in python. It kind of got out of hand – 1000s of developers and millions of lines of code. Yet despite being well resourced, we made the same mistakes that those tiny scripts you whip up to solve a small problem make. Come learn from our fail.

Mirroring all your repos from github

So let me be clear here, I don't think its a bad thing that Microsoft bought github. No one is forcing you to use their services, in fact they make it trivial to stop using them. So what's the big deal. I've posted about a few git mirror scripts I run at home recently: one to mirror gerrit repos; and one to mirror arbitrary github users. It was therefore trivial to whip up a slightly nicer script intended to help you forklift your repos out of github if you're truly concerned. Its posted on github now (irony intended). Now you can just do something like: $ pip install -U -r requirements.txt $ python download.py --github_token=foo --username=mikalstill I intend to add support for auto-creating and importing gitlab repos into the script, but haven't gotten around to that yet. Pull requests welcome.

How to maintain a local mirror of github repositories

Similarly to yesterday’s post about mirroring ONAP’s git, I also want to mirror all of the git repositories for certain github projects. In this specific case, all of the Kubernetes repositories.

So once again, here is a script based on something Tony Breeds and I cooked up a long time ago for OpenStack…

How to maintain a local mirror of ONAP’s git repositories

For various reasons, I like to maintain a local mirror of git repositories I use a lot, in this case ONAP. This is mostly because of the generally poor network connectivity in Australia, but its also because it makes cloning a new repository super fast.

Tony Breeds and I baked up a script to do this for OpenStack repositories a while ago. I therefore present a version of that mirror script which does the right thing for ONAP projects.

A sequel to Lock In, this book is a quick and fun read of a murder mystery. It has Scalzi's distinctive style which has generally meshed quite well for me, so it's not surprise that I enjoyed this book.

Once you’ve added oslo privsep to your project, how do you make a privileged call? Its actually really easy to do. In this post I will assume you already have privsep running for your project, which at the time of writing limits you to OpenStack Nova in the OpenStack universe.
