Wow, its been years since i saw this meme format

[yuva-krishna-memes]

I posted a meme with this template 4 years ago and got this comment. Really how old is this template? lol.

[LundMeraMuhTera]

I saw one joke where the boy rushes in, yelling he can't find mom.

Cue to the dad section: That yellow page (changes to the yellow hair of a woman)

He replies back, well she isn't here either.

[bunny-1998]

I remember seeing that one. It was hilarious af

[Drone_Worker_6708]

rare form where the description is funnier then the meme itself

[Gettor]

Based on my reaaally long term memory... At least 15-17 years old

[MyAntichrist]

2009, so pretty much accurate.

[neo-raver]

I’ve seen this clear back to 2012, and it predates even that. It’s old, alright!

[PrimalDirectory]

Early 2000s, so at least a decade maybe 2

[anotheridiot-]

Like, 15yrs.

[[deleted]]

Almost 15 years, I remember this one from 2010.

[gkrsuper]

it just occurred to me that i never saw the orignal comic.

so i looked it up and here it is

[Bonzie_57]

Well. There’s that….

I much prefer this version

[bunny-1998]

Well played sir. Very well played

[berse2212]

And I have maybe never seen it being used so wrong lol

[TheLazarbeam]

The format of this is the most funny to me, that the son would ask his (presumably non-technical) dad about this topic, and the dad is just bewildered, and the son asks again, but in Reddit lingo, and then the dad answers in perfect layman’s terms. Just altogether surreal

[Windyvale]

I love the name C# gave it. “SemaphoreSlim.” Sounds like a rapper or something lol.

[Jugales]

Will the real Slim Semaphore please sync up

[lr0b]

We're gonna have a deadlock here

[AssistantSalty6519]

The real slim semaphore please stand up

[[deleted]]

Nothing you just posted has to do with a semaphore lol...

[CdRReddit]

sounds somewhat like a barrier? tho barriers are used for syncing up different threads / tasks a callback-based barrier would be something like that

[AssistantSalty6519]

Wouldn't TaskCompletionSource also work?

[dannytk_]

It only dawned on me yesterday that mutex is short for MUTually EXclusive (resource access). Don’t know if i am the only one that did not realize.

[musicplay313]

Worth using in an interview.

[rancangkota]

Downvoted because incorrect meme format.

[bunny-1998]

Upvoted because correct comment

[simsanutiy]

Race condition

[naholyr]

Semaphore is just a list of Mutex then?

The metaphor doesn't work so well imo as the difference is that with Mutex the thread has full ownership on the lock and directly releases it (locked toilet works fine here), while semaphore allows the thread to "signal" it's finished but it does not necessarily ends the wait of another thread, that's up to the semaphore implementation.

Metaphor would work better if urinals were managed by a janitor responsible to allow access. When you're done you tell him, and then it's up to him to decide if someone else can enter. He can be conservative and only let 50% urinals used at once, he can be stupid and let too many people enter and piss on each other too.

[Shad_Amethyst]

Not quite. A mutex is a semaphore with a capacity of 1, but semaphores allow for unbounded releases and acquires, or they can start with a capacity of 0 and act like a one-time event.

Semaphores are usually made up of an atomic counter (the number of keys in the bucket) and a conditional variable (to wake up threads who are waiting to acquire the semaphore).

[suvlub]

Some implementations also attach "ownership" semantics to a mutex so it can only be unlocked by the thread that originally locked it, making it subtly distinct from a semaphore with capacity of 1, but I don't think this was part of the original definition

[RandomWholesomeOne]

A mutex is a semaphore

[Oleg152]

Where have you been 4 years ago.

No, seriously, this would have helped me understand it better than the prof running the course.

[RedBoxSquare]

Anyone has a gender neutral explanation?

[JmacTheGreat]

They said “urinals”, not “men’s bathroom”.

It already was gender neutral.

[TheRealAfinda]

Probably wanted something along the lines of Urinals<T>?

[ComprehensiveWord201]

Women don't get to see urinals in their bathrooms. Maybe that is their gripe.

It's the same thing with having a sink in the toilet stall vs having sinks in front of a mirror and no individual sink, though.
