Performance

Ratestate is a ratelimiter in the form of a [Node.js module](https://npmjs.org/package/ratestate) that can transmit states of different entities while avoiding transmitting the same state twice, and adhering to a global speed limit.

PHP's strrev is not safe to use on utf-8 strings because it reverses a string one byte at a time. So if a character consists of multiple bytes it cannot be preserved as an entity in the reversed result. There is no Multibyte String alternative to strrev either.

When designing systems, simplicity is an often heard mantra, but it isn't getting applied nearly as much as spoken of. I'm guilty of this too. I think it's mainly because engineers love to, well, engineer :) and will naturally try to [outsmart problems by throwing more tech at it](https://teddziuba.com/2010/12/the-3-basic-tools-of-systems-engineering.html).

I recently bought a NAS so my data is safe & available, with the benefit of being low power / noise / heat. I've considered Netgear, QNAP, but decided to go for a Synology as it was affordable, still had a big community, decent reviews & Time Machine support.

Some time ago I was in the situation where I was looking at 200 MyISAM tables screaming to get converted to InnoDB for performance reasons. You probably know that MyISAM is better at full-text searches and such, but what I needed was this database stop locking entire tables when I was just doing row-level interactions. Here's how I did **in one go**.
