The "shebang" syntax is the number sign followed by an exclaimation point and is embedded in most UNIX scripting languages to tell the computer what interpreter to use to run the script when the script is executed. This goes on the first line of your script, followed by the path to the program that will run, or interpret, you script, followed by a space and any other options you want to pass to the interpreter, finished by a carriage return. Nothing else can go on this line as seen in the Perl script below:

#!/bin/perl -w
#
# My first "Hello World!" script in Perl
#
print "Hello World!\n";
#!/bin/perl <-- Tells a computer to use the perl executable to run the script to follow.

#!/bin/ksh <-- Tells a computer to use the UNIX ksh (k shell) to run the script to follow.

... and so on...

murderhobo 

In a tabletop game, a murderhobo is a player who murders NPCs indiscriminately. This is normally derogatory, referring to a player who totally ignores quests, dialog, backstory, trade, world building etc.

The term is most common with Dungeons and Dragons, but it can be applied to most RPGs where the player is allowed to kill most quest-giving NPCs and NPC traders. E.g. Elder Scrolls, Fallout, Divinity original sin.

In sales terms, a whale is a prospect that is significantly larger than an organization’s average customer.

Whales are large and extremely difficult to close. Due to their immense size, they are highly sought-after.

A whale is typically identified at first by a whale hunter on the sales team, but often requires cross-discipline participation in order to close; this includes assistance from operations, engineering, creative, client success, and business development teams.
"Shit...the sales director chewed me out on the sales call this morning. He's totally pissed that I have nothing in my pipeline. I've been focused on this one whale for so long that I haven't had time to prospect for normal-sized deals."
