Ben Acker (@nvcexploder / Walmart) - Node in Production

• Impetus: Walmart wanted a mobile presence. They built an application that looked like it was created by a giant retail operation--SOAP services, etc.
• Started looking for other options: native apps,
• Started with services team (worked on original app, spinning out to other mobile apps)--all of a sudden had loads of different clients consuming the services. Converting old soap/XML into something mobile-friendly?
• High volume days (black Friday) start taking services down, and services team already distracted by mobile projects
• Time to start building better services
• Brought Eran Hammer over from Yahoo and gave him the go-ahead to use anything he wanted to improve mobile services. He chose node.
• Walmart's been open-source from the start
• But how to maintain legacy services?

The prep-script.sh will setup the latest Node and install the latest perf version on your Linux box.

When you want to generate the flame graph, run the following (folder locations taken from install script):

sudo sysctl kernel.kptr_restrict=0
# May also have to do the following:
# (additional reading http://unix.stackexchange.com/questions/14227/do-i-need-root-admin-permissions-to-run-userspace-perf-tool-perf-events-ar )
sudo sysctl kernel.perf_event_paranoid=0

Virtual DOM and diffing algorithm

There was a [great article][1] about how react implements it's virtual DOM. There are some really interesting ideas in there but they are deeply buried in the implementation of the React framework.

However, it's possible to implement just the virtual DOM and diff algorithm on it's own as a set of independent modules.
