ShadowBroker

This tool, ShadowBroker, that brings multiple OSINT feeds into an interactive map, so you to track aircraft, ships, satellites and global events.

When you zoom into the areas you're interested in, you'll find clusters of local news stories sorted by priority

It's pretty easy to set up and doesn't require any paid APIs.

In fact, it can work without any APIs at all.

Great tool

RaCo: Ranking and Covariance
for Practical Learned Keypoints(3DV 2026)

RaCo is a rotationally equivariant keypoint detector that identifies stable and repeatable keypoints in images. Refer the paper for a quantitative evaluation of its rotational equivariance.

[Philosophy Of Physics @PhilosophyOfPhy]

Sharp feather tips can be approximated by adding smooth sine and cosine waves. This hummingbird’s outline is described by two Fourier series, one for each coordinate. Their rotating chains position the pen where the horizontal and vertical guides meet.

Low frequencies capture the broad shape; higher frequencies recover smaller details. The number below the bird is the highest harmonic retained in each coordinate. At 100, the largest sampled pointwise error is about 0.57% of the outline’s height.

If you want a solid video course on 3D math for video games, that mixes both theory and practice, here it is: https://t.co/mYE346PzgS

Part I of the course, which is 14 hours long, is available for FREE. I recently split it into sections so that it's easier to get through. No section is longer than ~30 minutes.

The whole course is a hefty 50 hour ride so definitely a challenge, but I think it's worth it if you are serious about understanding 3D math.
