A JVM in Rust part 5 – Executing instructions

1. rjvm

   1 4 1,512 8.6 Rust

   A tiny JVM written in Rust. Learning project

   

   Your understanding of Rust is correct, but the code uses unsafe: https://github.com/andreabergia/rjvm/blob/93e7e48db085e780b0...

   As a result, when the VM gets dropped, the memory gets deallocated even if there are still objects that reference it.

2. Stream

   getstream.io featured

   Stream - Scalable APIs for Chat, Feeds, Moderation, & Video. Stream helps developers build engaging apps that scale to millions with performant and flexible Chat, Feeds, Moderation, and Video APIs and SDKs powered by a global edge network and enterprise-grade infrastructure.

   

3. computerraria

   2 13 3,677 6.8 Rust

   A fully compliant RISC-V computer made inside the game Terraria

   

   Take it full circle. Minecraft running Terraria emulating a 32-bit RISC-V CPU running Pong written in Rust - someone already did the latter part I believe, https://youtu.be/zXPiqk0-zDY?si=M0IHSzRLkaddwwKC

4. Graal

   3 179 20,978 10.0 Java

   GraalVM compiles Java applications into native executables that start instantly, scale fast, and use fewer compute resources 🚀

   

   Why would they? The direction for safer JVM research is to implement JVMs in Java, which has the advantage of being both memory safe outside a few tiny core areas (same as rust) whilst having cleaner code than the Rust impl (none of these problems with lifetimes).
