Re: Problems of an absolute beginner

That's a feature, not a bug. Some people had trouble with the push-to-latch uSD holders found in the Pi2B so the RPT swithed to a simple friction hold in the Pi3B. I sometimes mix up the two schemes because I forget that this is a pi2 or is it a pi3? It's not a good idea to be ripping the card out ...

Re: NHS attack on WinXP; would an RP be safer?

You are correct, but only as far as saying unpatched systems may be vulnerable to attack, this goes for any OS. So you aren't really saying anything. Of course something that is vulnerable to something and isn't patched against it is vulnerable. The relevant question between Windows whatever and Li...

Re: Files gone from an external HDD

The folder already had over 100GB of data in it. There's no point in having a back up system where I risk losing everything simply by interrupting a copying process.

Agreed. My guess is we will have to wait a bit and then a 20nm (or less) SoC Pi4 will appear (trouncing the competition probably). That would be....interesting. However, I don't expect it.

Because software lacks much or now sometimes even any incremental cost, the obvious solution is to just provide a free downloadable upgrade to the latest version if you buy the obsolete version now. That's usually not going to work with hardware, of course.

Do you need a pi to do what you want? They are not intended for this sort of thing and therefore require extreme measures compared to something like a microcontroller. Are you collecting data?
