 ## Learning Material Updates
 
+### [Rust on iOS with SDL2][rust-ios-sdl2-post]
+
+[![Rust on iOS with SDL2 demo](rust-ios-sdl2-screenshot.png)][rust-ios-sdl2-post]
+
+[@aclysma] published a [tutorial][rust-ios-sdl2-post] that describes setting up
+Rust/SDL2 on iOS. The resulting app can run in the simulator as well as on
+physical devices. [SDL2][sdl2-project] is a mature library providing basic rendering,
+audio, and input support. It can also be used to set up an opengl or vulkan
+surface. This demo is using [Rust-SDL2][rust-sdl2] for bindings.

 ## Library & Tooling Updates
 
+### Vulkan Renderer (Name TBD)
+

+
+[@aclysma] published a [new vulkan-based renderer][renderer-prototype] that
+uses [atelier-assets] to load 3D scenes exported from blender.
+
+> The objective of this repo is to build a scalable, flexible, data driven
+> renderer. Scalable in the sense of performance as well as suitability for
+> use in large, real-world projects. This means streaming, LODs, visibility
+> systems, and multi-threaded draw call submission need to be possible.
+> Additionally it means thinking through how an asset pipeline would work for
+> a team with dedicated artists and supporting workflow-friendly features
+> like hot reloading assets, possibly on remote devices.
+
+This video demonstrates the renderer running on iOS and receiving asset updates
+via wifi. The scene is "sponza" exported from blender. Vulkan is supported on
+windows and linux natively. Support for macOS and iOS is via the
+well-established [MoltenVK][moltenvk] project.
+
+The demo was ported from PC to iOS over a single weekend and out of
+approximately 300 crate dependencies (including complex, OS-specific ones like
+tokio), all but a few worked out-of-the-box!
