Flecs v4.1, an Entity Component System for C/C++/C#/Rust is out!
https://www.reddit.com/r/programming/comments/1lntgg1/flecs_v41_an_entity_component_system_for_cccrust/
<!-- SC_OFF -->Bit of background: Flecs is an MIT licensed entity component system (ECS). ECS is a design pattern used mostly in game development that favors composition over inheritance. An ECS can be implemented in a way that optimizes utilization of the CPU cache, and allows for late-binding behavior to game entities without having to resort to dynamic dispatch. To find more about ECS, see the FAQ: https://github.com/SanderMertens/ecs-faq/blob/master/README.md To find more about Flecs, see the Github repository: https://github.com/SanderMertens/flecs This release has lots of performance improvements and I figured it’d be interesting to do a more detailed writeup of all the things that changed. If you’re interested in reading about all of the hoops ECS library authors jump through to achieve good performance, check out the blog! <!-- SC_ON --> submitted by /u/ajmmertens (https://www.reddit.com/user/ajmmertens)

I built a web extension showing similar repositories on Github
https://www.reddit.com/r/programming/comments/1lnjenx/i_built_a_web_extension_showing_similar/
<!-- SC_OFF -->I trained a TruncatedSVC model on almost all Github stars to create embeddings for all repositories with more than 150 stars. I figured that could be useful so I fed the data to a Qdrant (https://qdrant.tech/) vector store and built an extension on top of it. Hope you like it! The extension is available on both Firefox (https://addons.mozilla.org/en-GB/firefox/addon/simrepo/) and Chrome (https://chromewebstore.google.com/detail/simrepo/jieoogmcigenidbkgnkaakagdnlnieap?authuser=1&hl=en) <!-- SC_ON --> submitted by /u/Mubelotix (https://www.reddit.com/user/Mubelotix)

Mochi v0.10.5: Support type-safe LINQ-style queries that compile to a bytecode VM
https://www.reddit.com/r/programming/comments/1llvbko/mochi_v0105_support_typesafe_linqstyle_queries/
<!-- SC_OFF -->We just released Mochi v0.10.5. It’s a small language that lets you write type-safe, SQL-style queries over JSON, CSV, YAML, or lists. Everything compiles to a register-based bytecode VM with constant folding, liveness analysis, and dead code elimination. If you’re learning how query engines or compilers work, this is a great place to dig in! <!-- SC_ON --> submitted by /u/Adept-Country4317 (https://www.reddit.com/user/Adept-Country4317)
