What We’ve Learned So Far

As I’ve been rebuilding this site. In case you hadn’t noticed. I have.

Cause of the hack.

And this is what I’ve learned so far…

Backups Aren’t Necessary UNTIL THEY ARE

If I had been maintaining regular backups (which the hosting company is totally happy to do for just a few euros more per month), it would’ve taken a few short hours (minutes? let’s hope I never find out.) to rebuild. Instead it’s been days. And it’s going to take at least another week to smooth out all the wrinkles.

So now I use Vaultpress, a WordPress plugin that interfaces with Jetpack, for daily backups.

All Your Repos Are Belong To Us

Today (and tomorrow) are the RDO Mitaka Test Days in Brno, Czech Republic and I spent a few hours this morning catching up on the tripleo quickstart live demonstration video and the rest of the day bashing my head against the packstack sanity checks for RHEL 7.2, CentOS 7.1, and Fedora 22.

And I took awesome notes. To share with you.

Cause I love.

There are quite a few prerequisites assumed which I’d like to clarify right now because I had to figure this out myself.

My ThinkPad W541 laptop environment:

I followed the instructions on https://www.rdoproject.org/testday/mitaka/milestone3/ to set up three virtual environments for testing purposes. This assumes you know how to set up a virtual system within Virtual Machine Manager which is fairly lacking, but the screenshots are helpful and the interface is fairly intuitive.

Note to self: write post about setting up virtual machines.

My goal for the day was to run a sanity check against packstack on CentOS, RHEL, and Fedora.

Change is Terrifying. Do it Anyway.

On Saturday, 05 March, I am one of the keynote speakers for Django Girls den Haag.

Hi. My name is Rain Leander. Welcome to Django Girls den Haag. Today I’m going to talk about programming – what it is, why you should do it, what you can do with it. I’m going to tell you my programming story including how I got the job I have now. And I’m going to give you a little programming advice.

First, what IS programming? Ashley Gavin gave a great TEDxNYU talk where she defines computer science as a medium for problem solving and self expression. Just like a dancer will solve a problem or express themselves with movement in space, a programmer uses technology.

But then why should you learn to program? There are so many reasons. Steve Jobs said, “Everyone in this country should learn how to program a computer because it teaches you how to think.” And code.org is putting out some great you-tube videos of “code super stars”saying that everyone should learn to program.

Paraphrased, some of the reasons include:
