Make sure you didn't miss anything with this list of the Best of the Week in the DevOps Zone (Apr. 18 to Apr. 24). Here they are, in order of popularity:
1. Infrastructure as Code: When Automation isn’t Enough
The best piece of advice to about using Infrastructure as Code is to stay connected to the vast community of innovative developers. If your systems remain open to the rapid changes in that community, you’ll be able to share and benefit from the cutting-edge ideas that will make your organization successful.
2. Loading Classes From Modules With Reflection in Python (Imp Module)
For a dynamic language, it’s more difficult than it needs to be to import a module dynamically in Python. It’s very easy to just from foo import bar, but what if you want to load a list of things and all you have is a string representation of each one, for example foo.bar?
3. Clojure: How To Prevent "Expected Map, Got Vector" And Similar Errors
What my Clojure code is doing most of the time is transforming data. Yet I cannot see the shape of data being transformed – I have to know what the data looks like on the input and hold a mental model of how they change at each step.
4. TDD and Rails - what makes a good Unit?
There is an ongoing discussion about TDD and Rails. It was recently
heated by some some of the DHH statements in his RailsConf keynote and
in a recent blog post.
5. Version Control of Your Linux Config With Git
Just keep in mind that you don’t push the git repository to some public space since the config files might include a lot of passwords. Also look out for his .gitignore in his case the printer does a lot of automatic changes and is thus ignored. You might have similar settings for your configs.
