Teaching new recruit some SQL (even though hes supposed to fucking know SQL and have multiple years experience but I was a contractor and idgaf, not messing up my money. Just fucking annoying to have an idiot around you all the time).

Me: Okay, so sys tables, so this one is for jobs yeah?

Him: Yeah

Me: Okay, so in this table, its obviously not one row per job per step cos you have multiple rows for the same job and step. Also, there is a datetime field, so what is it showing?

Him: Hmmmmm..... (after some time, back and forth we get to the answer).... history table

Me: Cooooooool, okay, so, lets say, I have a job with 5 steps. If i run it once, how many rows will be in this table?

Him: 5 rows.

Me: Correct, so if I were to have run this same job, 10 times, how many rows get inserted into the table?

Him: (Now...you have to understand, how long this thought process was, im trying to fill the gap with words but really, he was like, having a flashback or something...I kept quiet but silently wanting him to say anything....then he looks me dead in the eyes).... 10!

Me: Motherfucker what!?!? 10 What? If 1 time == 5, what does 10 times ==?

Him: Hmmmmmmmmm.... (yes...we are doing this whole flashback montage all over again)....... Ohhhhh, 1!

Me: .....Stop, think, its a history table. It holds history, for when every step is run for a job, why would it be only one row?

Him: OMG, I know what a history table is!!!!

Me: (Pissed off cos I don't take disrespect calmly). Fine, genius, answer, go!

Him: (LONGER WAIT THAN LAST TIME!!!!)....is it not 10?

Me: I swear, I'm gonna kill you one of these days.

Him: *chuckle*

Me: No...seriously....

TOOK 20-30 MINUTES FOR HIM TO SAY 50!!!!!!

And even then, I swear he didn't understand why. Serious, he was a special breed, had a manager that was a super tard and when I worked here, the spirit of that manager possessed this idiot, the CIO and his little right hand bitch zzzzzzzzzzzzzzzzz.

If there was ever a time I was willing to catch a case at work, it was there.

Bonus: Serious, it got to the point I had to come in and tell this idiot that he can only ask me questions today if he calls me by my name...and my name has changed today...and no, you can't ask me for it cos you need my name to ask me questions.....FUCK OFF kkthxbai.

This might sound trivial to most of you but recently I had my *mind blown* with a simple revelation.

When you use a ! as in "not equal to", you're actually performing a bitwise XOR to flip the bits.
