Semantic Highlighting in Neovim

What is Semantic Highlighting?
Default Highlighting
Using LspTokenUpdate for Complex Highlighting
- Highlighting Based on More Than One Modifier
Dealing with Ambiguity

Emscripten as a linker for Zig and C

This shows how to build a nontrivial program using Zig+Emscripten or C+Emscripten. In both cases Emscripten is only used as a linker, that is the frontend is either zig or clang.

"Nontrivial" here means the program uses interesting Emscripten features:

Asyncify
Full GLES3 support
GLFW3 support

Make Swift AD support all numpy functions via Autograd/JAX

In the Python module:

let autograd = Python.import("jax.grad")

extension PythonObject {
  @differentiable(wrt: args, vjp: _vjpDynamicallyCall)
  @discardableResult

Here's my experience of installing the NVIDIA CUDA kit 9.0 on a fresh install of Ubuntu Desktop 16.04.4 LTS.

	if [ -n "$folder" ] && [ ! -d "$folder" ]; then
