Set the default size for new Docker for Mac disk images

UPDATE: The instructions here are no longer necessary! Resizing the disk image is now possible right from the UI since Docker for Mac Version 17.12.0-ce-mac49 (21995).

If you are getting the error: No space left on device

Configuring the qcow2 size cap is possible in the current versions:

# my disk is currently 64GiB

Safari iframe cookie workaround

Safari by default discards cookies set in an iframe unless the host that's serving the iframe has set a cookie before, outside the iframe. Safari is the only browser that does this.

The 10k foot view

In order to get around the issue, the parent (src) and child/iframed/remote (dest) site have to work together, if the source site only wants users to access the destination via the iframe and can't assume that the user has visited the destination host before.

How to stream the London 2012 Olympics

There have been several HOWTOs posted regarding streaming the 2012 Olympics using HTTP / SOCKS proxies via SSH and other similar methods. None of these actually work using the latest Flash on Mountain Lion (with Firefox, Chrome or Safari). Additionally, the third-party streaming sites don't provide BBC's amazing interface, which lets you quickly skip to individual competitors and events. However, setting up an OpenVPN server does work, with some tweaks. You'll get the exact same UX that people in England receive.

• Get a Linode VM in the UK. The 512MB server for $20 works just fine. (If you want to use my referral link, go for it: http://bit.ly/OuzdVe)

• Follow the standard OpenVPN installation documentation. (Basically, 'apt-get install openvpn' or 'yum install openvpn' and then follow these docs: http://openvpn.net/index.php/open-source/documentation/howto.html). For an OS X client, I prefer Viscosity: http://www.thesparklabs
