    There’s no risk for a factory condition unit. This rumor started after people with units that had been dissasembled and reassembled had issues with vertical orientation. It turned out that it’s very easy to mess up the seals that keep the liquid metal thermal interface in place. So units that had been previously taken apart had liquid metal slowly leak, causing overheating and/or shorting.

    If you haven’t taken the cooler off the mainboard, using the vertical stand is just fine. I haven’t seen any evidence of factory assembled units suffering leaking. It does imply that user servicing of ps5’s is a bit risky, and you might need to be wary of used units where you don’t necessarily know the service history.

    To avoid unnecessary confusion, taking the covers off to add an m.2 ssd does not add any risk.


















  • I’m not saying normalization is a bad strategy, just that it, like any other processing technique comes with limitations and requires extra attention to avoid incorrect conclusions when interpreting the results.

    Because relative to the population density, there were 100 times as many sightings. Or what am I missing.

    If you were to attempt to trap and tag bigfoots in both areas, would you end up with 100 times as many angry people in a gorilla suit in the small town? No. You would end up with 1 in both areas. So while the tiny town does technically have 100x the density per capita, each region has only one observable suit wearer.

    Assuming the distribution of gorilla suit wearers is uniform, you would expect approximately 99 tiny towns with no big foot sightings for every 1 town with a sighting. So if you were to sample random small towns, because the map says big foots live near small towns, you would actually see fewer hairy beasts than your peer who decided to sample areas with higher population density.

    If we could have fractional observations, then all this would be a lot more straightforward, but the discrete nature of the subject matter makes the data imherently noisy. Interpreting data involving discrete events is a whole art and usually involves a lot of filtering.


  • Simple normalization does amplify signals in low density areas. If a person in a tiny town of 100 reports a bigfoot sighting and another person in an area with 10,000 population also reports a sighting, then with simple normalization the map would show the area with 100 people having 100 times as many big foot sightings per capita as the area with the population of 10k. Someone casually reading the map would erroneously conclude that the tiny town is a bigfoot hotspot and would in general conclude bigfoot clearly prefers rural areas where they can hide in seclusion. When the reality is that the intense signals are artifacts of the sampling/processing methods and both areas have the same number of fursuit wearers.
