Orthodox C++

What is Orthodox C++?

Orthodox C++ (sometimes referred as C+) is minimal subset of C++ that improves C, but avoids all unnecessary things from so called Modern C++. It's exactly opposite of what Modern C++ suppose to be.

Why not Modern C++?

Why coding streams/shows are interesting to me: in some livestreams, the experience is very similar to pair programming, 
but those people are experts. In VODs, it's more about problem solving and learning skills and approaches. The devs are really good
at what they do and there is *always* a lot to learn.

In no particular order:

1) Handmade Hero
About the author: Casey Muratori. Worked at RAD.
Description and why I like it: It kinda started the whole thing for me. Casey is coding a complete game and engine on stream, 
from scratch, one hour a day. He knows what he's doing on so many of the domains of game development and regular programing,

This list is provided as a guide for tools engineers of all skill levels looking for jobs in the game industry. It's meant as a guide to topics that should be pursued broadly in order to be well spoken in an interview. I doubt any hiring manager requires deep knowedge across every topic, but an ideal candidate would be somewhat knowledgable (aware of its existence if asked directly) with all topics here.

Each list of bullets increases in difficulty, so later bullets are more applicable to senior (or even director) level candidates.

Good luck.

Ellipsoid Frustum Intersection

Yesterday I posted a problem to math stack exchange that bothered me for a while now, and right after I've had a few exchanges on Twitter, I got inspired to attempt a solution.

Here it goes. It's 100% untested but I'm fairly certain that it will work.

The problem is about a form of refining raytracing where we render a big list of convex 3D brushes (and I decided to start with Ellipsoids, since they're so useful) to the screen or a shadow map, without any prebuilt accelleration structure. How does it work? Well, if we had a way to figure out for a portion of the frustum whether it contained a brush, we could
