2014/01/06 Linux.conf.au 2014 in Perth

It had been 11 years since I went to the last LCA in Perth, and I was excited to go again. As always, thanks to the volunteers who made this happen this year.

I was excited to do the arduino miniconf this year since it was to make a GSM phone.






this looks almost like my nokia phone from 1999

We had some good keynotes this year too, my eagerly awaited favourite being of course Jon's arduino in space.







And Tridge was the lucky deserving recipient of the Rusty Wrench award this year:


I definitely enjoyed his ardupilot talk



Of course, like each year, I enjoyed socializing with my international friends:

2014/01/06 My Live Upgrading Many Thousands of Servers ProdNG talk at Linux.conf.au 2014
π 2014-01-06 01:01 in Linux
LCA 2014 was the last event I gave my ProdNG talk at, the summary of 3.5 years of work at Google and the craziest upgrade I've done in my life. I also wrote a more detailled ProdNG LISA/Usenix Paper if you'd like more details.


The fancy talk description is here:

This talk will look at how we upgraded our ancient linux distribution on all the Google production servers to a more modern one based on debian stripped down and built from source.
We do live upgrades on running machines using an rsync-like rollout mechanism, and we slowly switched distributions on the fly without rebooting or downtime unless required by separately upgraded kernel, but doing a 10 year jump of linux userspace without breaking users was no piece of cake.
The talk will explain how something so crazy made sense, was even possible, executed, and worked out, as well as recommendations for maintaining linux big servers and dealing with upstream upgrades.

The video:

If you'd like the presentation in other formats:

  • ProdNG.odp
  • ProdNG.pdf
  • html (full screen)
  • More importantly, you can get the ProdNG LISA Paper which has many more details on how the upgrade went and the implementation.
