My first computer was a Radio Shack Color Computer 3 - 6809-based, running OS-9 Level II. It could run 32 processes at once, due to bank-switching a whole 1 Meg of memory.
After that, I got an AT&T 3b2, also known as a Convergent Safari. This was a Motorola 68010-based desktop.
Then, I graduated to a NeXT black&white "slab". I bought a used SPARCStation IPC in 1995, and put NetBSD 0.9 on it.
I've been using Linux since 1997, starting with a DEC Alpha-based UDB, and downgrading to a x86 PC in 2002.
I run Slackware and Arch linux.

How does systemd survive a kill -9? Thanks for noting that. Is this Linux specific? I seem to remember crashing a SunOS workstation back in the early 90s by killing init by mistake. Or not. I was a lot more reckless in my youth. |

Character count in Unix wc command @user3539 - It's traditional/convention for Unix/Linux/BSD text editors to put a newline/line feed at the end of the last line in the file, even if you don't. If you made the file with vi/vim, ex or ed, it did it for you. I don't know about all these modern, GUI editors, but I presume they do it too. |

How are the processes in UNIX numbered? Do you know what, if any, performance cost exists for this? |

What's the difference between a hard links and copied files? Peter's explanation is good, but he's left out "link count". In the file's inode (on disk metadata) there's a link count. A hard link increments the link count, a soft link doesn't. The kernel is allowed to delete a file's contents if the link count drops to zero. |

Convincing boss that I need to use Linux Yes, install Cygwin. "cmd.exe" is just pitiful, and the PowerShell thing looks like a swamp of complexity. I predict you won't get to use Linux, because your boss probably uses Windows. There's something addictive about Windows for people in management, and they can't seem to imagine that anything else is even possible. |

Why do inode-based file systems NOT need reboot after updating library versions? Two observations: some file systems (ReiserFS) don't really have "inodes", but they do store a file's metadata separate from the file's data blocks, and separate from the directory entry. Second, what metadata is kept in a location pointed to by the inode, and not in the inode itself? |
