  • When I was in high school, computers had Deep Freeze setup, because kids would constantly break the OS and download malware. It’s a software that resets the C drive to a known state on every reboot. You might consider using something similar on classroom workstations.

    Also, it might be worth learning about network booting, automating the Linux installer and ansible to install things on every machine at once and automate configuration work.





  • I own a Yamaha PSR E403. This series is a lower end class of synthetizer/arranger keyboards targeted towards novice players. Mine also has an identical UI to the one presented here. I wonder if the hack would work on it as well, being a similar model.

    My better keyboard is a Yamaha CP88 which is a lot more modern and has updatable firmware. I poked a bit with the update package using binwalk and as far as I could tell it’s not encrypted, and runs some version of QNX. My hacking skills aren’t as good, but I wonder if that one has similar exploits.
