Hello, I'm trying to figure out the best way to stream a live video feed from a webcam connected to a small computer such as a raspberry pi. Preferably the most lightweight solution to capture and stream the video across the network so it can be embedded into a website. I'm trying to use the...

Homework Statement Homework Equations CPU Time= Σ(individual IC time) The Attempt at a Solution What I did was first find the integer time, which is 100=75+X, and X is 25. To find the percent reduced, I did 100(1-x)=75+25(1-0.5). This means x is 0.125 or 12.5 %. Is this correct?

Hi guys, Can anyone suggest me some of the must read books for a computer science student for learning new things and improving the programming skills! Thanks in advance [emoji3531]

Hi, it's been a long time since I've been on these forums, but here is a new 3D blender model that I spent four weeks of daily work to finish. I'm glad it's done, it wasn't easy. This is metal gear RAY, a 70-foot tall robot from the popular video game franchise metal gear solid.
