I have this C program that rotates a character matrix. This is a straightforward rewrite of this Java implementation. Both versions do additional $ \Theta(mn)$ preprocessing and require $ \Theta(mn)$ additional space in order to run arbitrary rotations in $ \Theta((m + n) \min (m, n)) = \Theta(\max(m, n)\min(m, n)) = \Theta(mn)$ time. rotable_char_matrix.h #ifndefRead more

In my spare time I’m working on simulating a Rubik’s Cube in excel using VBA: So far I have code to rotate the top and the front of the cube. Currently I store the values of the left, back and bottom cubes on a hidden sheet called “Placeholder”. I refer to the front, top andRead more

I am looking to buy an inflatable pillow, preferably ultra-light material, and inflatable by hand, not by blowing with the mouth. May be with a small hand piston or hand pump. There are these torch lights that charge by rotating a handle, somewhat like that. To be used in (Indian non-AC) trains. I am notRead more

I want to create a plane 2d sprite plane that looks at a 3d object and then rotates by its z axis. So I have created a LookAt Function in my game which will make the object look automatically at the sphere, but it is executed every frame, I believe this is because it makesRead more

I’ve got a 64 bit bitboard, but instead of interpreting as an 8 by 8 binary matrix, as is usually the case, I’ve taken it to the third dimension, so to speak. Now mirroring and even rotating by 180 degrees on any individual axis is, if I’m not mistaken, fairly simple, but rotating by 90Read more

Hi, does any one know if there exists any service that offers proxies which will randomly select end-IP from the pool for each request? Most services rotate proxies every 10 or 5 mins but I wonder if there are ones that offer new IP every time I do a request.Read more
