comment Does the “Massive Growth in SMTP STARTTLS Deployment” decrease SPAM filtering efficiency?
Nothing Unix/Linux specific about this. security.SE would be more appropriate.

Some firewalls/UTMs with deep packet inspection filter spam on the fly before it reaches the mail server.

comment Ruby commands are turning off tty echo
@PaulRoub, possibly something starts an editor with the output discarded. dtruss -f may be able to tell you what commands it runs, and/or what does the ioctl that disables echo (run dtruss stty -echo to get the ioctl number).

comment How can I mount a disk image?
You don't need the -o loop above, /dev/mapper/loop0p1 is already a block device (a mapper device on top of a loop device, you don't want another layer of loop device on top of that).

comment Why is Bash everywhere (in most if not all Linux distributions)?
@EvanTeitelman, yes, bash programmable completion appeared years after zsh's which itself appeared years tcsh. zsh caught up with tcsh in the mid 1990s, bash caught up with tcsh in the mid-2000 but is still a decade behind zsh

comment What's different between Ctrl+Z and Ctrl+C in Unix command line?
Yes, my command was about your CTRL-Z suspends the process... which may mislead people into thinking it is sent to just one process when it's actually a job or process group.

That's jobs (process groups), not processes that CTRL-C, CTRL-Z, fg and bg deal with.

comment What's different between Ctrl+Z and Ctrl+C in Unix command line?
Yes, though Ctrl-Z (and CTRL-C) causes a process group (the foreground process group of the terminal) to receive that signal, not necessarily only one process. Also note SIGTTIN and SIGTTOU sent to processes not in the foreground process group of the terminal when then attempt to read or write from/to it, that also suspend them.

No, that's SIGTSTP, not SIGSTOP and it can be intercepted.
