Hate

Posted on by 
Love is a word that is constantly heard,
Hate is a word that is not.
Love, I am told, is more precious than gold.
Love, I have read, is hot.
But hate is the verb that to me is superb,
And Love but a drug on the mart.
Any kiddie in school can love like a fool,
But Hating, my boy, is an Art.

xargs

Posted on by

Maybe, I’m the lost person to realize the functional awesomeness of xargs(1).

Without xargs(1):

% i=0; for j in $(jot 100 1); do if [ $i = 4 ]; then printf "%2x %2x %2x %2x %2x\n" $s $j; s=""; i=0; else i=$((i+1)); s="$s $j"; fi; done

Sysadmins never take vacations…

…they always stay on call. :)

“Exactly. Simple as that. Can’t have you having bad dreams, and I’ve paid my dues. From now on, I’m only going on night call to cover holidays.”
She laughed. “Sysadmins don’t take holidays.”
“This one will,” he said. “Promise.”
