* This is roughly the code I found. A callback is passed in props,
* and the author attempts to make a debounced version of the callback
* so that it will only trigger at most once every 200ms.
* Debounce is used when we are getting lots of events and want to
* avoid a costly operation (e.g. network request) on every one. It
* wraps a callback and returns a debounced callback that will only
* trigger the callback on the newest call when there is a break in
* activity. A common use-case is to request a search as a user types,

node setup on RHEL6

These are the steps I used today to get node installed and working on my Red Hat Enterprise Linux 6 machine. Note that the first step can cause potential issues, so you should understand and weigh those up. You can skip the first step, it just means you will have to run global module installs (npm install -g ...) with elevated permissions (sudo/su).

  1. change owner of /usr/local so that npm install -g will Just Work. I think this has to go before installing node so that everything works properly.
sudo chown -R $USER /usr/local

If you just want to watch the talk, you don't need anything. If you want to follow along or play around with webpack and/or browserify at the camp, I recommend preinstalling the following before setting out.


Just in case the npm mirror is not available at the camp, you can preinstall the following if you want to play around with browserify and webpack:

install nodejs

nodejs is the runtime on which webpack and browserify run (just in case youmanaged not to hear about it somehow)
