Thank you, this worked! The date I accidentally moved the file was recorded as the "Change:" date and I was able to find my lost file :D

File Browser Undo Function

In the default file browser program (PCMANFM ?), is there or could there be an undo function? Or, could anyone recommend an alternative lightweight file browser that has such a function?

Re: Is it possible to adjust when a Pi3 boosts CPU speed under load?

Great, that does seem to work, thank you!

Setting up_threshold experimentally to 10, with cpu_freq_min=250 and core_freq_min=200 takes me from a typical current draw of 0.97A to a fluctuating 0.93 to 0.95A

A bit more tinkering..

Thanks!

Re: How best to log 12 volt lead acid battery voltage with a Raspberry Pi?

Many thanks for the replies, the INA226 sounds exactly what I want, especially with the code examples to work from.

I've not yet tried this out - been busy with other things - but want to test it soon. Will post back here when I've done so

How best to log 12 volt lead acid battery voltage with a Raspberry Pi?

I've got some solar panels that charge a lead acid battery via a cheap solar charge controller. This battery then runs some low voltage items in the house, such as the router, a Pi based NAS and soon a few lights. I've also got an emergency backup that cuts in if the battery voltage drops below 11.5...

We normally don't update packages for previous releases, but given how recent Buster is, I've pushed out a VLC update for Stretch as well.

It should be public within about an hour.
Thank you, that's working great now - cpu load 10 - 15% instead of 100% when playing video in VLC.
