Re: How do I remove the sticky heatsinks from a dead Raspberry Pi and reapply them to a new one

To remove the heatsinks, use a thin bladed knife and cut through the thermal pad. Then use alcohol solvents to remove what is left of the thermal pad from the heatsinks. After that, apply new thermal pad/tape to stick the heatsink on another Pi.

Tilde really should be the default editor on all distros. it uses the keyboard shortcuts one would expect a GUI editor to use.
Thanks...but I'll stick with vi. And, indeed, as part of what I do setting any new Pi is to establish vi as the default editor.

A "169.254.*.*" IP address pretty much means "I don't have an IP address". That is, DHCP upsteam of the Pi (probably your router) isn't providing a local IP address. So, effectively, you don't have access to the internet and pinging a publicly addressable IP address--such as 8.8...

Re: Pi W Zero, Stay on!

The Pi should stay up. The problem is to keep the process you started going. There are a couple of ways to do that. You can start the process by prefixing "nohup" (no hangup), or issue a "set nohup" before starting it. Next is to run the shred as a background process by appending...

But one source suggests the ...
