It's a "drop everything and patch" if you have a large multi-user server where you don't completely trust all of the users. Like say in a university with a server that students can log in to, like I have just had the joy of updating (and had RHEL break ZFS on me yet again).
But yes, in most other cases no it isn't a "drop everything" exploit - but it does mean one less layer in the multi-layer security, as unprivileged remote exploits now become root-access remote exploits.
I used one of these to win an inter-school science competition when I was ~13. It was a minute timer. The competition board doubted I had built it all myself, so they plonked it down in front of me and demanded I draw the circuit diagram in front of them.
Every EEPROM is basically that, and they're designed for data retention of around 100 years. I imagine it wouldn't be hard - embed two metal plates in glass?
To go along with these, aurora light consists of emissions at specific wavelengths, and this can potentially interact with the optical system of the camera you use to produce interference patterns. If you see these patterns (which can appear as rings of light and dark around the middle of the photo) then that indicates that a good portion of the light is at least monochromatic, which very strongly indicates aurora. If you don't see them, it means nothing - your camera might just not have an arrangement that does that.
Yeah. Recurring card purchases are hard to stop. They can keep going even after the card has been cancelled or expired. The direct debit guarantee is so nice in comparison.
