Luau – fast, small, safe, gradually typed scripting language derived from Lua

In addition to a completely custom front end that implements parsing, linting and type checking, Luau runtime features new bytecode, interpreter and compiler that are heavily tuned for performance. Luau interpreter can be competitive with LuaJIT interpreter depending on the program. An optional component for manual Just-In-Time compilation is also available for x64 and arm64 platforms, which can considerably speed up certain programs.

The Outsiders is a beautiful new exercise app from the developers of Gentler Streak

Intel Patents 'Software Defined Supercore'

If the technology works as it is designed to, then Intel's future CPUs could offer faster single-thread performance in select applications that can use SDC.
