i think the 0.15 cents refers to what the nano 3 earns per day.

thanks, i think you're right.

the fact they make like $0.15 per day

last time i hired an engineer from that part of the world, it cost $75k annual. cheaper than other places, but the 15 cent myth is something i've not been able to replicate.

I could bust out the watt meter and see what power consumption it's using if nobody has numbers for that yet.

that would be interesting.

if you think you can do better there are many open sources that you can improve on and where you could make your contribution.

that would be a worthwhile suggestion if my 25 year contribution wasn't already out there.

as for Canaan's shipments, we just have to compliment them on the excellent logistical work they are doing with thousands of orders in a short time!

you may compliment them if you like. i found the 22 email "updates" each containing excuses like "we were on holiday" or "we will do better this week", not to be compliment worthy. for me, they fell more into the underwhelming category. i'll save my compliments for people who keep or exceed the promises they make. companies that already have a successful manufacturing and distribution network, but choose to launch a new product on a crowdfunding platform where late delivery excuses are the norm, are not in a category that warrants compliments from me.

  • the shipping logistics are sub-par.
  • shipping devices that all have the same factory root password in 2024 is lazy at best, willfully negligent is more likely.
  • a "factory reset" that does not reset the pool configuration is sub-par.
  • the firmware's tendency to change or corrupt the root password frequently, is unacceptably sub-par. i've had both of mine for a week. their credentials have each become corrupted 3 times in that short timespan. that's just pathetic.
  • when i buy a device that has an ssh server set up and running on it from the very first boot, i want to have access to the credentials that ssh server accepts and i want to be able to lock people who are not me, out of that device which i own and which runs on my network. i don't want unknown persons to retain valid credentials for that device. nano 3s are shipped with a running ssh server whose credentials are not provided in the device documentation. there is no conceivable explanation for this arrangement that puts canaan in a positive light

i have no praise for anyone who delivers sub-par, but as i said, anyone can compliment them if they're happy to spend their money on sub-par.

i think deliberate mischief on canaan's part is unlikely. my own experience of these devices is that a higher than acceptable amount of stupidity went into their production. i agree with hanlon. they're not malicious, they're stupid.

There is probably a backdoor in the firmware. An attacker can change the custom root password (no, it's not root in my case, it's a complex one) or there is a manufacturer password.  Stay behind your firewall and do not open any ports to the outside.
i have two nano 3s. both of them often become inaccessible with the password i set them to. the only way to log in to them, when this happens is to reset to the root/root credentials that canaan ships them with, then change the password again. i haven't yet seen the pool address change or anything like that. mine sit behind a regular home router without any port forwarding so i'd be surprised if someone other than canaan is responsible for the password changes. there's no way to reach them from outside of the home router.
if someone is hacking these boxes, then my money is on canaan or one/some of their engineers doing it with dodgy firmware. they're just not reachable from outside of the home network, so the only way to mess with them is from the firmware. since i've never seen a pool address change happen, it looks more like crappy firmware corrupting the root password than an actual hack.
hanlon's razor admonishes: never attribute to malice that which is adequately explained by stupidity. given the incompetence of the canaan team in predicting shipping dates, it's not hard to imagine they have a whole stupid farm also working on their firmware.
