It's a fantastic photo ๐
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
How can you argue with a word like "best' anyway ;)
A lot of the underlying libraries in python are actually written in Fortran (or were when they were conceived, and the Fortran components later replaced). Numpy, for example, was originally pretty much a wrapper on top of BLAS and LAPACK.
This gets even more complex if you're using a toolkit of some sort. C++ has a batteries-included way of doing something, then STL has another, and Qt yet another... Etc.
Don't get me wrong. There is still a time and a place for Fortran. And this will also likely always be the case for C++. But I'm not sure it is entirely wise to choose it if you're creating a new project anymore.
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.
