I like Deke's ^Deke thing.

Shumon Huque
3:35
I guess it's better than ^Shumon. EOF is a better parting line than pause ..

John Speno
3:36
i always assumed it was regex like and not an eof

Shumon Huque
3:37
could be. not a very interesting regex though ..
we'll have to ask Deke for the definitive answer ..

John Speno
3:38
I think it's him, standing in front of a distant mountain.

Shumon Huque
3:38
ha ha. or maybe it's just a carat character for no obvious reason ..

John Speno

carrots are pretty much always pointless

Mark Sirota
3:39
I think I once knew the answer to this, a long long time ago...

Shumon Huque
3:39
pointy haired bosses are known for pointless things ..

Mark Sirota

Carrots are pretty pointy.  If you've got pointless ones, shop elsewhere.

It's CNTL-D, over and out.
EOT.

John Speno

I take it back. I don't like it anymore

3:41 Tomo Takebe left the room. (in disgust?)

Shumon Huque
3:41
I think it's "Control-D epic kamikaze end"

3:42 Tomo Takebe entered the room.

Mark Sirota
3:42
Maybe it's an imperative: Control Deke.
