Only Connect to One of Multiple Interfaces at a Time, Using Priority? (DHCPCD)

Hello all, RPi 3 on the latest Stretch. I have a spare Wifi USB dongle I'd like to use, for the most part. I have it configured for a static IP so I can reach via home-local domain name. But sometimes I need to steal that adapter for a different machine. When that happens, I would like the network t...

Re: Protecting SD Card: Delay before poweroff?

I never realized that SD card corruption was a danger when cutting the power to the RPi. That makes it a little impractical to use as an embedded device (imagine having to do a graceful shutdown when you unplug your microwave oven or TV). Well technically you can boot with the OS in read-only mode,...

Re: Protecting SD Card: Delay before poweroff?

Hmmm great tip on not yanking the power right away. I'm sure I've done that more than once on accident. Regarding the "sudo reboot" being misleading. No that's really what I'd done. I updated my Pi from a remote location a few times. Basically the process was: SSH in, Enter "screen" to protect from ...

Protecting SD Card: Delay before poweroff?

Hey all, I was just wondering if you think it'd make sense to add a delay during the shutdown process, such that the Pi would wait an extra 30 seconds or so before actually powering off.. and if so, how to go about doing that? I just got this idea thinking about the last few times I borked my OS. Ea...

Hey all, Just a suggestion here. I'm getting the following warning when logging into the Pi via SSH: SSH is enabled and the default password for the 'pi' user has not been changed. This is a security risk - please login as the 'pi' user and type 'passwd' to set a new password. But the thing is, I've...

If you don't mind a small additional service on your machine, webmin makes these kinds of things extremely easy. I setup my own new PI to be a slave-dns off my main server in like 5 minutes.

Last I remember, bitcoin was already at a point that even a big fast computer with a great GPU would still burn through almost more electricity than the money it generated. I think this plan is several years too late, unfortunately :-\

Okay thanks guys. I think I'm sold on just the GPU/load aspect of it.

When I do get one, would I have to access frames/pixels the normal (ie: hard haha) way via Java, or does it have some special API to make things a bit easier?
