That is perfect. Or even part time (just mine when you aren't using the computer). Every little bit helps. Also, ask your friends to do the same.
I installed version 0.9 and downloaded the blockchain from scratch. Absolutely amazed how quickly it synced (overnight), and only uses ~70 mb of RAM. Amazing job!
About the solo mining you are encouraging. Do I actually make a valuable contribution to the network when I only have 12 MH/s and 8+0 connections (I can't map a port since I do not have access to the router. So I assume I am not a full node).
You are a absolutely a full node.
No question that 12 H/s is very low, but every bit helps. But if your computer is horribly inefficient (e.g. no AESNI) then I wouldn't really encourage it, because it is just wasteful. Better that you help support Monero in other ways.
Even that you can do, if the other node opens its port and yours connects to it. Once the connection is established it works the same regardless of who had the open port.
Thanks for the answers. I actually realize that I am mining with ~75 H/s and the net hash (of the total network?) is 10.12 MH/s.
Regarding the full node, it seems that currently I am not uploading any data (which seems to be indicated with the 8+0 connections).
Do I actively need to change a setting to be able to connect to another node that opens it's port?
Today I will try to setup a full (
