Which is hilarious because I recently got told I was being insulting for merely asking how one should pass comments on to the Foundation after Eben had said "We're listening to people’s comments about what they’d like to see in a new Raspberry Pi".

Re: Forum structure

Some people tell me that suggesting the clever folk behind the Raspberry Pi don't know what they are doing and suggesting improvements or how things should be different is insulting them. So I'll sit this one out as I don't want to get banned for insulting anyone.

Re: How to shut down a rasp you cant connect to

You could also short and hold the Reset input pad to 0V which will slam it to a halt before pulling power. That will stop any odd things happening while pulling power, as power collapses. Note the two adjacent Reset pads can be shorted on all Raspberry Pi's except the 3B+ which has a different pad a...

Re: Sensing 50Hz frequency deviation fast

For certain you cannot do this with just a Raspberry Pi I am not entirely convinced that is the case. To measure to 0.1Hz accuracy requires timing the 50Hz ±2Hz period to about 40us resolution. If pigpio can time a signal to a resolution of 10us or better then it would seem to be possible. That's a...

Re: Why does the RPF care about how many desktops I have ?

Taking it a step further, how about a config file where you could specify that you never want raspberrypi-ui-mods to mess with your ~/ files at the cost of not getting further updates to those files?

Re: Can I "passthrough" a keyboard (act as keyboard) on an Rpi

You should be able to use two Pi Zeroes; one as a USB Host handling the physical keyboard, the other as a USB Device acting as a virtual keyboard for whatever it plugs into. The data could be passed between the two using UART serial easily enough and other GPIO mechanisms could work. Turning that po...

Depends on what you consider "Raspberry Pi" to be. ...

Potentially an infinite number of devices though it may be fewer depending on how those devices need to be served, the mechanism required to do that serving.

Removing unwanted apps has always worked for me without any unexpected side effects so maybe you did just pick on a bad app to delete.
