Hi,
I have read in some posts here that the Rock64 can benefit from some passive cooling such as heatsinks. First, I assume that the Rock64 does not come with them. Correct? Second, can someone suggest an appropriate heatsink to purchase? I have pre-ordered a Rock64 and would like to be prepared for its arrival.
Thank you,
JL

I submitted a request for a coupon code to order the 14" pinebook about a week or so ago. Should I have expected some sort of e-mail acknowledgement so that I know if I am in the queue? Also, how long is the wait to receive the coupon code to place my order?
Thank you!
J.

| Recovering root access in Ubuntu |

Yesterday I had cause to add the ubuntu user to the www-data group. I believe I did this:
Code: # usermod -G www-data ubuntu
Since then, I am unable to become root. If I try to sudo -i, I am told
Code: Sorry, user ubuntu is not allowed to execute '/bin/bash' as root on pine64.
This happens no matter what command I try to run. sudo vim /etc/sudoers?
Code: Sorry, user ubuntu is not allowed to execute '/usr/bin/vim /etc/sudoers' as root on pine64.
I don't actually know if adding ubuntu to a group caused this; it's just the biggest change I've made, and I can't think of anything else I've done that would cause this.
Thanks!

First of all, congrats for a very interesting product.
THe board looks very good from a specs. point of view, but what about the power consumption?
How much power does it need in idle and how much power does consume under full load?

Hi guys,
i require your helps and ideas.
i run openssl speed rsa to evaluate the power of my PINE64+ board (i am a crypto guy).
i was a litle bit surprised to see big difference using different distribs :
- the Debian Jessie with Mate DE [3.10.102 BSP 2] by Lenny Raposo show me a nice 9.6 4096bits Private RSA / sec
while other dietPI and armbian get stuck to 6.4 4096bits Private RSA / sec.
So i decide to upgrade both the Debian Jessie Mate and dietPI to the latest kernel 3.10.105, run package update, then i force the CPU setting got from the debian to the dietPI :
sampling_down_factor = 1
sampling_rate = 2000000
sampling_rate_min=40000
up_threshold = 95
but got same result dietPI still show me 6.4 4096bits Private RSA / sec.
What do i miss ?
Any helps appreciate, thanks a lot
