nginx config for http/https proxy to localhost:3000
First, install nginx for mac with "brew install nginx".
Then follow homebrew's instructions to know where the config file is.
1. To use https you will need a self-signed certificate: https://devcenter.heroku.com/articles/ssl-certificate-self
2. Copy it somewhere (use full path in the example below for server.* files)
3. sudo nginx -s reload
4. Access https://localhost/
Edit /usr/local/etc/nginx/nginx.conf:

Fix Ubuntu and other Linux slow/hanging file copying via USB.

If your running a x64 bit Ubuntu or other Linux and find USB transfers hang at the end apply this fix:

echo $((16*1024*1024)) > /proc/sys/vm/dirty_background_bytes
echo $((48*1024*1024)) > /proc/sys/vm/dirty_bytes

I suggest you edit your /etc/rc.local file to make this change persistant across reboots.

sudo nano /etc/rc.local
