Minimal D3D11

Minimal D3D11 reference implementation: An uncluttered Direct3D 11 setup + basic rendering primer and API familiarizer. Complete, runnable Windows application contained in a single function and laid out in a linear, step-by-step fashion that should be easy to follow from the code alone. ~200 LOC. No modern C++, OOP or (other) obscuring cruft. View on YouTube

Also check out Minimal D3D11 pt2, reconfigured for instanced rendering and with a smaller, tighter, simplified overall code structure, or Minimal D3D11 pt3, with shadowmapping + showcasing a range of alternative setup and rendering techniques.

If you enjoyed reading this, I'm intending to do more blogging like this over here: https://cdgd.tech

This is not a complaint about Webpack or v4 in any way. This is just a record of my process trying it out so I could provide feedback to the webpack team

Hmm... I don't see any docs for 4.0 on https://webpack.js.org. I guess I'll just wing it. All I need to do is npm i -D webpack@next, right?

+ webpack@4.0.0-beta.2

Qlobe

Qlobe is a fascinating example of quine in Ruby, submitted by a member of the Ruby core team - Yusuke Endoh.

Programs that output changed executable versions of themselves while managing to spin the globe and still remaining executable are cool, right?

To experience its magic, run the following
