"Mastering" in its original sense is producing a master stamp for pressing vinyl records, the term has extended to recording raw tracks, tuning, mixing and compiling them into finalized tracks to be put on a master disc or tape ready for replication.

Remastering means the raw tracks are mastered again using newest technologies, like hi-res encoding or surround sound/spatial audio .etc.

Car windows are much more better built for a variety of reasons, while bus windows aren't.

Car windows are designed to resist being pulled around without power for security reasons, the window tracks and actuators are very tight. Bus windows don't need that and are just tempered glass panes put on a sliding track or regular window frames.

Bus windows are also much bigger, their natural frequencies being lower and closer to the engine/road vibrations making them easier to go into harmonic oscillations when on the road. Perhaps the frequency didn't match when driving, but it definitely did when you lean on it like pressing the string on a guitar, making it vibrate with the engines.

Because that's not real troubleshooting, instead it just lets you revert back from a known good state, the starting state.

Real software troubleshooting is not only expensive, but also out of regular user's capability to collaborate.

Fast charging is just an alternate way of delivering power through standard 5V USB lines.

Regular USB lines are rated at 5V. To allow transmitting higher power without ramping up the amperage, you add voltage instead.

This creates a problem that the same connector now comes in higher voltages, which older device may not be able to withstand and will just fry if clueless users plug them into the new charger.

So There is a series of protocols to authenticate between the charger and the receiving device before it switches to fast charging, without authentication, the charger only outputs at 5V.

For charging time, OP did not provide enough information, like the model of the phone, charging from what percentage to what percentage and the temperatures. Charging will become slower above 80 and even below 80 if the temperature is out of the safe range.

PC owners technically have full admin rights to their operating systems, therefore with the correct knowledge and tools, they are able to inspect and modify any aspects of any programs running on it, including any game DRM checks.

Therefore all modern PC anti-piracy schemes are built on the principle of obfuscation, just scramble the piece of code and make it a huge headache for a human to descramble and reverse engineer to skip all the checks.

Therefore it is only a matter of time before all the checks are found. PC game publishers now only uses this time difference to cover themselves to sell most of the expected sales, and update the game once one major version has been cracked to protect their online gaming services as much as possible from cheating.

Console disc-based copy protection however still relies on hardware. Discs are produced to contain errors that are genuinely impossible to replicate as long as you don't have the original stamps, and the disc drives contain special firmware to look for those errors. Consoles check these areas to determine if a disc is genuine or a burned/pirated pressed copy.

Console digital copy protection works on the assumption that console owners DO NOT have full admin rights to the OS, and therefore the hardware encrypts EVERYTHING to prevent inspection and modification of the code as much as possible, guarding the code even from users.

OP tried really hard to emulate the working process of executives, but cannot reach fidelity whatsoever. Turns out there is no working process anyway and it was just overthinking.
