+## Other Projects
+
+In this section, we describe updates to Rust OS projects that are not directly related to the `rust-osdev` organization. Feel free to [create a pull request](https://github.com/rust-osdev/homepage/pulls) with the updates of your OS project for the next post.

+
+Added a little GUI for visualizing memory maps. The application itself currently supports a map format that my initialisation code emits, but
+it has a MemorySource trait that you can implement to consume any format.

+### [`metta-systems/vesper`](https://github.com/metta-systems/vesper)
+<span class="maintainers">(Section written by [@berkus](https://github.com/berkus))</span>
+
+Vesper has learned to put nucleus into higher-half memory and added a kernel syscall API with a single syscall - a capability invocation. I have a list of capabilities I want to implement, and first one implemented is Debug Console so you can output execution trace from your domains.
+
+Init thread implementation in progress, now parsing DTB and preparing to launch a user-space "init" process. The video above shows memory map produced by the init thread after parsing a RasPi3 B+ 1Gb DTB.
