A mistake can be valuable or costly, depending on how faithfully you pursue correction

    Indeed. I don't read reddit, but read about Moe from the horse's mouth.

    perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'

      When I heard, I thought it was insane. The title of his talk offended me...

      Then I went and read it. Then I thought about how awesome it would be *starry look in eyes*. I thought about the fun, the possibilities. I felt inspired. I began to understand... that it just. might. be. true. maybe.

      Time will tell, as it always does. I hope it does "light the fire", bring about the changes we need. We deserve the Perl that he's talking about. We can do better, and we should.

[Corion]: Maybe doing a double-fork (daemonizing) can make go that information away, but maybe not
[Corion]: But I think my knowledge of unix/Linux datastructures is several decades out of date, so I don't really know what information it keeps on processes
[oiskuu]: The useful bits that relate to your process can be found under /proc/self. What information are you thinking of? Tty name?
[tye]: I just daemonized and getlogin() still knew who I had been.
[tye]: perhaps loginuid ? Not that I concede that something not being in /proc means it is not useful.
[Corion]: tye: That's really interesting, but maybe it is because getlogin() returns the name, or the uid, so if that user has been replaced by another user with the same uid in the meantime, that's no problem to the system...
[davido]: or on ubuntu /var/run/utmp
[Corion]: Otherwise, I would imagine that a user with a process still alive would lock that information in memory.
[davido]: so last -f /var/run/utmp on ubuntu provides similar (though more verbose) info
[oiskuu]: glibc getlogin just does ttyname() and falls back on getutline(); it's not security related at all. (reminds me of sendmail and remote finger services of the naive early spam era)
