An awe-inspiring C exploit imo.
I found it on YouTube and, as my friend Nolan reminded me the other night, this algorithm is not new. The fast inverse square root shook the nerd world with its implementation in Quake III (1999).

:: learning about quadcopters by building one

I used a soldering iron and a raspberry pi during lockdown to stay sane.
My introduction to quadcopters and robotics in which I learned a lot about the quad ecosystem and their constitution. However, I suggest following a smaller, cheaper, and more recent build guide. Although my naivete showed through here, my fascination with quads has not soured; check out my Tello face following and vSLAM project!

PCA vs. autoencoder: the ultimate dimensionality reduction showdown
I fell in love with dimensionality reduction when I was learning statistical ML. Since I also study neuroscience, I wanted to practice the art at the intersection of my interests. I compared the 3D projections of a 53-dimensional neurophysiology dataset produced by PCA and a shallow autoencoder.
