[BLADESHARK]

Well, if I AM REALLY DISTURBING YOU GUYS,,

Never known these things bcoz I don't drink

Gee Blade, you don't have to be a drinking man to understand what Daniil explained. Indeed, I betcha anything that the vast majority of heavy drinkers aren't even aware of the information Daniil posted, most of which is pure math.

BTW, I drink only occasionally and even then I rarely go beyond 2 drinks in a sitting.

HAHAHA! Oh my God!

Me? A bot? Haha!
Do I really disturbed you guys?
Ok, a great idea to create just one forum for all the things I'd like to share.

I am a human from Philippines. >___<

UPDATE
I did passed on chemistry subject but I forgot on computing efficiency... 
For the reason I cant answer, then you'll conclude I am a bot? But dont worry, i am not offended... but rather, it makes me laugh.

Moreover, I cant be an attacker too for the reason, I am a Civil Engineering student and I know less bout codes. Wew!

The suspected bot is a Filipino! lol  This is gonna be the 3rd time but I'll say it again - Welcome, Odlanyer22!!!

My lil bro is a Civil Eng'g student, too. All he does is make models for his projects.

OK, comrades.  Sometimes any of us may acting like a bot, for example, at the evening of Friday after a week of work, or after an extra drink.
But let's get back to subject. What kind of question can help to distinguish human from machine?  (Maybe it's about a kind of Turing Test?  )

Uh, bots.. Got to hate them, they are everywhere. Though its nice when "people" are the suspected bots.
