Arduino - need reassign Timer 0 overflow (TIMER0_OVF_vect) to different ISR - how?

On a generic Arduino (ATMEGA386P) -based application, I need Timer 0's overflow interrupt (normally goes to TIMER0_OVF_vect) to point to my own code, not the ex

Figma SVG not parsing with flutter_svg

I have created a bunch of vector graphics I want to use inside my flutter application but cannot seem to load any SVGs from Figma using flutter_svg. This is the

Unity: Convert Vector2 to Vector2Int

I have a Vector2 and I want to convert it into a Vector2Int. I know I could convert the Vector2 with something like this: Vector2 v2 = new Vector2(10, 10); Vec

Is there multiple ways to cin vector elements?

I have a program that adds multiple vectors in 1 vector. I saw a method of instead of .push_back to add elements and I used it, but I am wondering why this work

Updating an intrinsic rotation with an extrinsic rotation

I am trying to model a Rubik's Cube for a personal project, using Zdog for lightweight 3d graphics. Zdog uses a {x,y,z} vector to represent rotation - I believe

How to plot wind vectors on wind map

How to implement outer product of two vectors in Scheme?

I want to define a function in Scheme that will compute the outer product of two vectors. for example: (outerProduct '(1 2 3) '(4 5)) the output is supposed to

Cache-friendliness std::list vs std::vector

With CPU caches becoming better and better std::vector usually outperforms std::list even when it comes to testing the strengths of a std::list. For this reason
