Did you know? The β€œping” command, commonly used to test network connectivity, was developed by Mike Muuss in 1983 for BSD Unix and later became standard in Linux and other operating systems such as Windows and others. Check his Wikipedia page https://en.m.wikipedia.org/wiki/Mike_Muuss and my page about ping command https://www.cyberciti.biz/faq/unix-ping-command-examples/ examples for more info. #linux #unix #macos #freebsd #history #opensource

Most folks don’t realize it, but BSD greatly contributed to modern computing. Linux, macOS, iOS, and gaming consoles or streaming service are the most successful examples that borrowed ideas and code from the BSD world directly or indirectly. Even at one point windows used networking stuff from BSD world. How often do you ssh into servers and network devices? That code comes from the BSD world too.
@nixCraft the first inkling something was up was when I found the hosts file in Windows is in c:\windows\system32\drivers\etc\hosts
@whatatoots @nixCraft Apple wrote a tcp/ip stack from scratch from spec, and it was an interop disaster. Like causing other machines to crash disaster.
MS was prudent in porting the stack from BSD.
@whatatoots @nixCraft It was also, in retrospect, a sign that the core of the internet was far too trusting.
@nixCraft Lots of things come from Plan9 too! The IPC and filesystem sharing used in WSL is from Plan9, and many of the concepts have been implemented in both the Linux and Darwin kernels
@nixCraft are you referring to winsock?
@nixCraft The /system/bin/sh on billions of Android devices #mksh comes from #MirBSD (with thanks to #OpenBSD).
@nixCraft They don't?! Where were they during the Unix wars then?
