[REQUEST] Youtube video tutorial for dual-install Ubuntu + Remix OS |

Seems we would be receiving our Pine 64 now
Now, the OS seems an issue due to small developments and may take some time until a stable release is done? I miss kind of clear software support section by Pine64 staff
I request someone to publish (when possible) a step-by-step Youtube tutorial for a dual install of Ubuntu 16 + Remix OS 2.0
I think a minimum sd card with 16GB would be ok
Thanks

Low power headless operation? |

We are currently using a very expensive but low-power arm sbc for long term field monitoring and control (embedded hardware). Has anybody looked into how low the power could go if we turned off power to the accessories that wouldn't be needed like HDMI video to audio in and out, SATA, camera, things like that? I think we could even get by with running on a single core. This is probably far outside of the intended audience of the board but that is our application and I thought I would ask.
One thing that is a definite kick in the nuz is that there is no onboard eMMC. I have plans to keep this in the field for months at a time even up to a year between service intervals. I'd rather have one place to store the data and another place to boot the OS but such is life. There is an ODROID board that allows you to have onboard be MMC but I don't know very much about it or about power consumption.
So, the final question: is it an ill-fated attempt to try to take the power out of the pine 64? If so, does anybody have any recommendations?
BTW power on our current board is about 0.5 Watts at idle

Hey folks,
This is meant to give an idea of backers who have received their boards, so if you've got yours, post a reply with your batch and when you received it.
I'm a February early-bird backer and I'll update this post after mine arrives.
EDIT: Based on the latest update, looks like my board is going to be delayed because I added some accessories (Camera, RTC and WiFi/Bluetooth modules). That's disappointing. If this information was available earlier, I wouldn't had added any accessories to my pledge.

Hi,
I don't see any secure payment method...
I saw Paypal is coming with the store but what about https or other secure payment ?
I am ok with CB transaction but is doesn't seem secure, isn't it ?
Thank you
