Gacha mechanics are patentable in games in Japan?

Man, patents just need to go away.

I can hear the spurs jangling. Can you?

Tl;dr: Bleach is a salt with one of the ions being unstable. When that ion decomposes, the resulting oxygen and chlorine are disruptive to other chemistry.

Salts refer to the type of bond involved -- ionic bonds. Typically a salt is a positive ion and a negative ion that just sort of stick together due to their charges. These bonds aren't very close, and a salt molecule is easily dissolved in water. Once in water, the ions just sort of mix freely with the water molecules.

So here's the thing. Household bleach is sodium hypochlorite, which is technically a salt. They just sell it already dissolved in water at the right strength. The sodium ions in it is identical to the sodium ions in table salt. But the hypochlorite is the key here. This ion is made of a single oxygen and a single chlorine bound to one another. The hypochlorite isn't actually that stable (the solid form could be used as an explosive, actually), and in the presence of other molecules, tends to break down releasing oxygen and chlorine, neither of which are stable by themselves and will prefer to bond to something immediately. Both oxygen and chlorine are strongly electronegative and will bind fast and hard to other organic materials in such a way that they disrupt those materials. After the materials are disrupted, they tend to dissolve easier in water for removal.

Tangent: most household bleach has a significant amount of sodium chloride in it, as a byproduct of the manufacturing process. And it isn't worth it to purify the sodium chloride out of it so they just leave it in there.

Pub owner knows how to get the cats to sit -- random cardboard box lids haha

Oddly enough, it's probably one of the best and most affordable devices in this sector. You can buy 10-20x units compared to the brand leader (Trimble). So I think they assume that this is how most people will operate.

It's a fantastic photo 😍

They're lithium iron phosphate chemistry, which typically draw down to 2.0V without problems, and tend to be a bit more forgiving. I agree 0.9V is low, but the cells were relatively new. Furthermore, no sign of damage or other typical faults associated with a failing battery, and my battery analyzer (from my drone batteries, same chemistry) approved it. According to my gantt chart, they've likely been charged and discharged 75 times since I brought them back to life.

Sadly, because they are a manufacturer device integrated battery pack, and the manufacturer doesn't sell replacements, my only options would be installing a third party battery pack or buying another device at $1500 or more. I'm happy with the battery recovery process though in this case.

Assuming it isn't a fisheye lens, then the best reference is the fence and trees in the top left corner. Without that fence though I think it would be a lot harder :)

Probably you should add yourself to the list on Wikipedia then ;)

I thought the movie Tenet made this up :)

It's barely even funny at this point.

Although I'd quibble about Newsweek defining this guy as an oligarch. He was vice president at a company that was disbanded due the company president's opposition to Putin. It's very possible this guy is just a former executive that refused to bend or hand over some dirt or something. It doesn't appear he fits the definition of oligarch at all.

Unless we're just using the word to refer to all Russians above peasant.

It was designed from its very start to be used for numerical computing. So the language it built around it and it sort of excels in that use case.

This used to be the holy bible of numerical methods, if you want to see some sample code: https://s3.amazonaws.com/nrbook.com/book_F210.html

I have a 750m 0.75mm² wire on a spool that needs a quick disconnect connector of some sort on it so it can take it off in 250m lengths. But it has to handle the tension of being spooled up. Any ideas?

In an ideal world it would be a male and female banana plug thing, but that wouldn't hold under tension. So I'm hoping you folks have ideas.
