Ansible 1.3 Conditional Execution -- Very complete example with comments -- I find the conditional expressions to be ridiculously hard to get right in Ansible. I don't have a good model of what's going on under the surface so I often get it wrong. What makes it even harder is that there has been at least three different variants over the course …

# ansible-playbook -i hosts ansible_conditionals_examples.yaml --extra-vars="hosts=myhosts isFirstRun=false"
# ansible-playbook -i hosts ansible_conditionals_examples.yaml --extra-vars="hosts=myhosts isFirstRun=true"

Truncating html with nokogiri, with/without Rails
View Explanation.md

Rails has a handy truncate helper (which is actually mostly a method added to String ), but it warns you it's not safe to use on html source, it'll cut off end tags and such.

What if you want an HTML safe one? There are a variety of suggested solutions you can google, none of which were quite robust/powerful enough for me.

So I started with my favorite, by Andrea Singh, using nokogiri.

But:

  • I modified it to not monkey-patch Nokogiri, but be a static method instead (sadly making already confusing code yet more confusing, but I didn't want to monkey patch nokogiri)
