Re: Safe SSH access to Pi over internet

It depends upon your level of paranoia and the added inconvenience. Keys are more secure, but password over ssh is probably secure enough, particularly if you ever want to login from a different computer eg. perhaps from a mobile phone or tablet that doesn't have the key installed. Communication ove...

I am thinking about the new user. I'm thinking about the thousands of new users that have got their new Pi and plug it into their router at home and it doesn't work.

Re: How to start without HDMI monitor?

If you are in the US then you could try the following from Amazon: http://amzn.to/Q2vXBM

I can't confirm it definitely works, but it looks and sounds the same as mine which does work (although a different colour cable). Costs about $20.

Re: How to start without HDMI monitor?

HDMI to VGA is much easier than people think.

It does need a converter to go from digital to analogue, but these can be built into a cable and fairly inexpensive. The one I am using cost £15
