How old is this house?
In 1971, the US National Electrical Code (NEC) required grounded receptacles in all locations of the home (effective January 1, 1974).

You can check with a $6 electrical receptical tester.
It could be that the electrical system was grounded to the waterlines that enter the house (those should definitely be copper).
The ball is in the DEA’s court. Some say it should be rescheduled by Spring:

How long the DEA might take to form a response is an open question, though experts told MJBizDaily that an initial proposed rule could be issued by the end of the year and the process finalized by next spring.
What the DEA cannot do is reject the HHS recommendation outright, said Howard Sklamberg, who once served as the U.S. Food and Drug Administration’s top enforcement official.
This means marijuana’s days as a Schedule 1 drug are ending. It’s only a matter of when.

Even better, find someone who talks in an American accent who wants to speak in your old accent.
Agree to bump into each other hard in front of your friends, when you get up, switch accents.
Alternative, celebrate your birthday together and each can wish for the others accent.
Also, server side anti-cheat computation costs the gaming company money.
Though you’d think some forms of cheating would be computationally inexpensive to detect, like teleporting and such.
It depends on when you were around and reading geeky news sites. FUD came up often on Slashdot in relation to Microsoft:

and the SCO v. IBM section are relevant.

True on the digit by digit code decryption. That I can forgive in the name of building tension and “counting down” in a visible way for the movie viewer. “When will it have the launch code?!” “In either 7 nano seconds or 12 years…”
If they had been more accurate, it would have looked like the Bender xmas execution scene from Futurama:

I did like the fact that they showed war-dialing and doing research to find a way into the system. It’s also interesting that they showed some secure practices, like the fact there was no banner identifying the system or OS, giving less info to a would be hacker. Granted, now a days it would have the official DoD banner identifying it as a DoD system.
I remember with Windows 95, LAN Manager passwords were hashed in two 7 digit sections which made extracting user password from the password hash file trivial:

Looks like it was worse than I remember. The passwords were first converted to all upper case first!
In addition to the explanation others have mentioned, here it is in graph form. See the where the graph of 2^x intersects the y axis (when x=0):
https://people.richland.edu/james/lecture/m116/logs/exponential.html
This also has some additional verbal explanations:
http://scienceline.ucsb.edu/getkey.php?key=2626
The simplest way I think of it is by the properties of exponentials:
2^3 / 2^2 = (2 * 2 * 2) / (2 * 2) = 2 = 2^(3-2)
Dividing two exponentials with the same base (in this case 2) is the same as that same base (2) to the power of the difference between the exponent in the numerator minus the exponent in the denominator (3 and 2 in this case).
Now lets make both exponents the same:
2^3 / 2^3 = 8/8 = 1
2^3 / 2^3 = 2^(3-3) = 2^0 = 1

For the Quest 2, the ideal setup is a dedicated (but inexpensive) router for wireless communicating with the headset. Last I looked a few specific models of semi-generic $50 routers were tested by the community.
Then you can either run your PC lan connection through that router or if you have a second Ethernet connection, use one just for that router.
Frametimes is the specific measure.
<11.1ms for 90Hz or <8.33ms for 120Hz
If the game, experience, or whatever breaches that minimum frame time frequently, then you can experience nausea just from moving your head around.
It does require some sacrifices like turning shadows down a notch or two in some game engines and choosing additional visual effects carefully. Some visual effects require additional computation passes and can add the the frame time.
A low latency CPU (like the AMD 3D cache CPUs) or a normal mid to high end CPU with fast memory with good timings helps quite a bit.
The GPU should be capable of pushing the pixels and shading for the target resolution. Even with a 6900xt I’ve been able to comfortably push over 4500x3000 per eye rendering (enough to get a nice anti-aliasimg effect on my Pimax 8kX at the “normal” 150 degree H.FoV) in most games.
Surprisingly, fidelity FX can help as well (the non-temporal version).
adding a virtual nose decreased motion sickness significantly
Behold, the VR headset of the future!
Would be nice if the author had done a bit of research on the specific things that had been done in VR since he tried his DK2 to prevent nausea:
An Oculus DK2, a PC that couldn’t quite run a rollercoaster demo at a high-enough framerate, and a slightly-too-hot office full of people watching me as I put on the headset. Before I’d completed the second loop-de-loop, it was clear that VR and I were not going to be good friends.
The study the author quotes dates to August 2019!
For one, non-persistent displays have become the norm. These only show (strobe) the image for a fraction of the frame time and go black in between. Valve discovered that the full 1/90th of a second an image is displayed is enough to induce nausea if the head is moving during that time. So the Vive (and the Oculus Rift) had non-persistent displays.
The stobing effect is so fast you don’t notice it.
Elimination of artificial movement is another. The reason Valve focused on games with teleport movement and made a big deal of “room scale” early on was to eliminate the nausea triggers you encounter in other types of experiences.
Valve had an early version of Half Life 2 VR during the days of the DK2, but they removed it as the artificial motion made people sick (myself included).
For many, sims work as long as there is a frame in their field of vision to let their brains lock into that non-moving frame of reference (ex car A-pillars, roof line, dash board, outline of view screen on a ship interior, etc). Note the frame still moves when you move your head, so it’s not a static element in your field of view.
Also it helps if your PC can render frames under the critical 11.1ms frame time (for 90Hz displays). Coincidentally, 90Hz is the minimum Valve determined is needed to experience “presence”. Many folks don’t want to turn down graphic options to get to this. It’s doable in most games even if it won’t be as detailed as it would on a flat screen. Shadows is a big offender here.
Resolution isn’t as big of a factor in frametimes as detailed shadows and other effects. I have run games at well over 4k x 2.5k resolution per eye and been able to keep 11.1ms frame times.
Lastly, it has been noted that any movement or vibration to the inner ear can for many stave off nausea. This includes jogging in place while having the game world move forward. For many years we’ve had a free solution that integrates into Steam VR:
https://github.com/pottedmeat7/OpenVR-WalkInPlace
Jog in place to make your character move forward in the direction you’re facing. Walk normally to experience 1-to-1 roomscale.
I’ve use the above to play Skyrim VR without any nausea. Good workout too!
For car, flight, spaceflight simulators, a tactile transducer on your chair (looks like a speaker magnet without the cone - or basically a subwoofer without the cone) can transfer the games sound vibrations directly to you and therefore your inner ear and prevent nausea.
I’ve literally played over 1,000 hours of Elite:Dangerous this way as well as Battlezone VR and Vector 36. All games that involve tons of fast artificial movement.
The main issue is too many people tried out VR cardboard or old DK2 demos with low and laggy framerate, persistent displays, and poorly designed VR experiences and simply write off all VR as bad and nausea inducing.
Edit: added links and trailers to the games mentioned so folks can see the motion involved. The “study” wasn’t a proper study. It was a quote from a scientist. No data was given about what headsets or which experiences caused nausea.
First off, the water would need to be desalinated or you would ensure the land would be unsuitable for farming (and really growing anything) for generations.
Also, sand doesn’t hold water. In fact, when planting trees and other bushes, if you want more drainage, you typically add rocks and sand.
Second, most plants need non-sandy soil to grow on (palm trees and other beach bushes and plants aside) though those grow in areas that have lots of rain already.
Thirdly, the soil will need bacteria to aid the plants in obtaining nutrients and breaking down waste (dead leaves, dead plantlife, etc).
The way to do it is to look at a couple of projects that are fighting against desertification in Africa:
The Great Green Wall https://education.nationalgeographic.org/resource/great-green-wall/
Using compostable waste to fertilize soil https://jstories.media/article/greening-the-desert-with-trash
You’ll notice that many of these projects start at the edges of deserts. Instead of relying on pumping water onto sandy soil (which would just suck up the water as sand doesn’t hold water that well) they focus on extending the non desert ecosystem onto the desert so that the new soil will absorb water better, the weather over the newly terraformed area will be less dry, and it will eventually be self sustaining.

Looks like $26.99 is the lowest it’s ever been on Steam.
I would check two things:
Is it a QLED tv? Those are very efficient with the backlight power. QLED only have a blue led backlight and the “quantum dots” in the panel between the backlight and the LCD panel absorb the blue light and emit the red green and blue needed to create the full color spectrum.
How many nits of brightness does it produce? I’d check for the specific model on RTINGS. It won’t help OP much if the TV is efficient, but so dim that it’s unusable in their case.
Reflectivity also helps with brightness when viewed in a bright room. The less reflective (matte) the less brightness the TV needs to overcome distracting light sources reflecting on the screen.
Edit: Had to look it up to be sure, normal LED panels use filters that filter red, green, and blue light from a white light source. This means roughly 1/3 of the light from the backlight is filtered away, hence the energy inefficiency vs QLED which uses the energy from the blue light to create the colors.
Intestingly, some DLP projectors use alternating red, green, and blue light sources which strobe on the DLP chip which takes turns modulating the intensity of each color. Less efficient (and bright) DLPs use a single white light source and a color wheel (rotating color filter).
