A bit off-topic for minimized editor bandwidth, but fine with "End
of an Era".

The "Timing Analysis of Keystrokes and Timing Attacks on SSH"
[1] attack on OpenSSH (that lead to ObscureKeystrokeTiming
ssh_config(5) option, aka "obscure inter-keystroke timings from
passive observers of network traffic") was one of my deepest
"boah!"s/take a deep breath of the last years.

Compared to when i discovered Linux, but then FreeBSD with all the
documentation and papers, and all that, and reading code, of
course, over 26 years ago, it lost its, well, innocence.
By then, at my programming level at least, you disabled Nagle's
algorithm, and at worse used SSL, to mischieviously rub your hands
and be fine with it.
