+1 for trying to answer the question behind the question (XY problem, and so on). If I could, I'd give you more.

Accessing dict_keys element by index in Python3
...
In many cases, this may be an XY Problem. Why are you indexing your dictionary keys by position? Do you really need to? Until recently, dictionaries were not even ordered in Python, so accessing the first element was arbitrary.
I just translated some ...
Increasing the maximum number of TCP/IP connections in Linux
...lways talking about IP+port. You can have "unlimited" sockets open to port XY from many different IPs. Limit of 470 applies to concurrent opened sockets to the same IP only. Another IP can have its own 470 connections to the same ports.

Circle-Rectangle collision detection (intersection)
...ct is rect.x & rect.y are the center of the rect. In my world a rect's xy is top/left of rect, and 0,0 is top/left of the screen, so I used: circleDistance_x = abs(circle.x - (rect.x-rect.w/2)); circleDistance_y = abs(circle.y - (rect.y-rect.h/2));

@mstrap: so it is an XY Problem after all. Well, you can look into differential updates of jars (so even one-byte-differences would not cause the whole jar to be redownloaded) and you should provide explicit version numbers to your releases anywa...
Principal component analysis in Python

@Alex Fair enough. I think this is another variant of the XY problem - the OP said he didn't want an SVD-based solution because he thought SVD will be too slow, probably without having tried it yet. In cases like this I personally think it's more helpful to explain how you would tac...
Why is SSE scalar sqrt(x) slower than rsqrt(x) * x?
...w. You can try f(x) = x^2 - 1/y, but it will be equally complicated: dx = 2xy / (y*x^2 - 1) for instance.
One non-obvious alternate choice for f(x) is: f(x) = y - 1/x^2
Then: dx = -f/f' = (y - 1/x^2) / (2/x^3) = 1/2 * x * (1 - y * x^2)
Ah! It's not a trivial expression, but you only have multiplie...
