Steam cleaning urine is a bad idea. The heat will cause it to bind to the carpet even better and make it even harder to get rid of.

it’s obvious their pets handled the moving process poorly and have urinated in every room with carpet

Cleaning up pet urine can be really expensive depending on how bad it is. If it’s not just a few spots here and there, seriously consider ripping out all of the carpet and padding and living on the floor boards until you can get new flooring.

You should buy a black light. Nothing expensive, $20 or so. And shine it on everything with the lights off, urine glows. As a side note, anyone looking to buy a house, or even get a new rental should get a black light.

It’s about $50 a month. Nothing gets released at my house, which is nice. I’m a little out of my depth with the chemical reaction, but the idea is inside the tank are a bunch of resin beads impregnated with stuff calcium and magnesium ions will bind to. So as water flows through the tank the calcium and magnesium is removed and stored in the beads. So the beads store it, but can’t store an infinite amount. The tank gets switched out every 2 weeks and culligan takes the old tank back and reverse the process. I’m sure this involves nasty stuff, but hopefully economy of scale and regulations make it a cleaner process than just dumping the salt in the ground.

Brine discharge can be pretty bad for the environment, so we do some tank exchange thing with Culligan. Every other week they install a new tank and remove the old one to be recharged. Working great so far.

Not really, you can get all the same benefits with adding extra memory without having to deal with setting up and managing a massive RAM drive.

When a program or the OS itself needs to read data from the disk, it does a disk read operation. Before reading the data directly from the disk, the OS checks if the requested data is already present in its cache. If the data is found in the cache (a cache hit), the OS can retrieve it quickly from the RAM, avoiding the slower disk access. If the data is not present in the cache (a cache miss), the OS reads it from the disk and also stores a copy in the cache for future use. If the cache is already full, the OS needs to make space for newly read data. There are various strategies for what data to evict, but something will be bumped out of the disk cache, it’s fast, but not free. The data stays in disk cache until it gets evicted to make space for something else. If you have enough memory, nothing needs to be evicted so even if the game unloads assets, the files on disk are still cached and can be accessed without loading from the physical disk.

So point being, if you have enough memory, after the data is read once, it’s going to stick around in memory and be access just as fast, and maybe a little faster than a RAM drive. Why maybe a little faster? A RAM disk is effectively double caching the data, once in the RAM disk and once in the disk cache so you need twice as much memory to not have cache misses. Imagine a game that has 10 GB of data on disk, lets ignore the memory it takes to run the game, os, etc, just think about that 10 GB of game data, disk cache, and RAM drive.

Say you have 16 GB of memory. 10 GB of that will need to be made into a RAM drive, so we have 6 GB left for disk cache. When you’re playing the game, it’s going to try and access that 10 GB of game data, it’s first going to look in the disk cache. The cache is only 6 GB, so the game can’t fit entirely, sometimes the data will be cached, sometimes it’s not. When it’s not, it’s going to go through a few extra steps to remove something and fetch the requested data from the RAM drive. The data eventually gets loaded from RAM, but with a few extra steps. Now without the RAM drive, there would be 16 GB of disk cache, the game will fit entirely. Once it’s all loaded, no more disk access, it’s all in memory.
