NVidia made PhysX open source in 2018, and it was free to use before.

No, I mean Luau itself. I distribute Luau as dll by default, but without the analysis module, to keep it small (~600KB). If users want to have analysis, they need to build Luau from source. Bindings are not an issue, since they use only C API from Luau, which is fast to compile.

Fast hot reload is not Luau specific though. Lua and LuaJIT reloads fast too, so does JS and most other scripting platforms. In fact, I have subsecond C++ hot-reloads.

Do you have a link for the official Luau Discord? I can't see anything on their webpage or github and google is not helpful either.

Yes, I mean Luau itself, not the scripts.

I used to use Lua and later LuaJIT in Lumix Engine. I switched to Luau because of its type system. However, it's apparent it was not meant to be used outside Roblox, as it has many rough corners. The documentation is not great, and the community is basically nonexistent - I got zero results when searching for any issues I encountered. Also, it's huge compared to Lua or LuaJIT, causing my project to compile 7x slower. The API is not great (e.g., an async API that blocks, using STL in the API, leaking STL headers). I encounter bugs with analysis/LSP often. Overall, I consider moving away from it.

I recently fell in love with node-based editors so I'm working on several plugins for my game engine https://github.com/nem0/LumixEngine, e.g. node-based procedural geometry plugin, node-based image editor, visual scripting or node-based level generator. I am also thinking about using WASM as runtime for the visual script, which also means easier support for scripting in other languages which can compile to WASM.

I only mentioned Win32. There this library is very inefficient compared to ReadDirectoryChangesW, which consumes no CPU times when nothing changes.

Looking at Win32, it scans the whole directory periodically, right? I must miss something, but how can that be called efficient?

Making native UI in Java on Android is such huge PITA. While I've never used js/html app that was not bad, it's still 10x better.

You are right, I should have written "you probably can" instead of "you can". But my original point is that that

> it's better to present yourself as an anonymous avatar than a real person

is not what's implied from the article. Rather it should be:

"it's better to present yourself as an anonymous avatar than a real person if you want to receive less crap"

Note: there's a user in this discussion saying in their case image of good looking woman worked the best.

No, the person is using sexism of other people, but that does not mean he/she himself/herself is sexist.

>But there's no sexism involved here?

I'm only saying a person using good looking woman as an avatar because of a/b testing does not make him sexist.
