I'm building a box to house my 3D printer, and I wanted a 12V supply to power LEDs and a extractor fan - so I raided the "dead phone" box and grabbed a barrel connector PSU and started looking for a panel mount female 5.5mm OD.
That's when I discovered there are two types: ID or 2.1mm or ID or 2.5mm.
And a little research* gave me the "official test" to find out which is which.
Grab a toothpick, break it in half. Stuff it in the hole in the middle. Turn it upside down. If it falls out, it's 2.5mm, if it doesn't, it's 2.1mm.
Because there is an standard for the thickness of round toothpicks: 2.1 to 2.2mm
And that's what I learned today: someone, somewhere, documented the size of a wooden stick ... and everybody went along with it. 
* OK, OK ... a quick Google

My toothpicks are triangular.

Which size would you like? Just take your pick.

I think what it teaches me is that we may need to wait a few more thousand years before we actually reach a standard for power connectors. But that we'll get there in the end, just like toothpicks.
(Imagine the problems people had hundreds of years ago... "Hey, Bathilde, pass me a toothpick..." "Sure, a 2.1mm or a 2.5mm one?" )

I just noticed an advert on the Codeproject ad section on the header. It was for Intel and it made reference to OpenVINO. I don't know, but to me that sounds clearly like a subliminal message (or maybe direct instruction) to open a bottle of wine........
Maybe it is a new naming convention, we will get CrackATinny and ProseGO or even HangoverSSL next
¯_(ツ)_/¯

No, that would be political - and that's not allowed in the Lounge.

I may or may not agree with such a sentiment, but I'd not mention it here.

There's a Linux distro that's literally named Wine 
Anyway, some old VB or JavaScript is much more likely to get you on booze than OpenVINO or Wine are

Me: hello, AAA? I'd like roadside assistance please?
AAA: Where did your car break down?
Me: The car's fine, it's me who is having a breakdown. Please come and get me now, thanks.
When I was growin' up, I was the smartest kid I knew. Maybe that was just because I didn't know that many kids. All I know is now I feel the opposite.

Maybe you had better called the AA

I'm about half serious and half crazy. I'm inclined.

Looking at youtube... same could be said about idiocy 
M.D.V. 
If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you
Rating helpful answers is nice, but saying thanks can be even nicer.

Was trimming the hedge and I "found" a wasps nest in it.
Seems to be roughly the size of a football.
What would be your next step?
I'm contemplating burning the hedge, it has become a bit tall anyway.
<edit>No, I'm not seriously considering burning the hedge down. For the exact reasons already stated in some answers</edit>
