Windows Subsystem for Linux (WSL)
https://learn.microsoft.com/en-us/windows/wsl/Windows Subsystem for Linux (WSL), also known as "Bash on Windows," lets developers run a GNU/Linux environment directly on Windows, including most command-line tools, utilities, and applications. This functionality is offered unmodified and without the overhead of a traditional virtual machine or dual-boot setup.
I was a member of the initial core team that spearheaded this technology. My responsibilities were initial socket networking subsystem bring-up, accessing the Windows file system from WSL, and Linux and Windows program interoperability via pipes. I also performed debugging support, including GDB, Strace, and core dump bring-up, as well as critical applications bring-up for Git, Emacs, and SSH.
