It’s sort of minimalistic / lightweight alternative for IntellJ. Red Hat is working on the extension(s) which have worked fine for me at least for the past few years and it gets updates regularly.
I use VSCode for C++, C#, Java, Python and for things like docker-files, html etc. IntelJ is fine but a bit bloated in comparison with its menus, sub-menus, sub-sub-menus and built in unnecessary extra features for those just looking for code editor.
VSCode workflow with Java is mainly using it to write code, run tests, configure maven/gradle/docker/etc rest is more or less using CLI and Command palette.
Would assume that in this case that the gpu was created and assempled using a open blueprint/schematic thats freely available for anyone to see use and modify. Fairly common thing when it comes to stuff like 3d printing where many people freely share their models for others to use.
