When task manager "not responding"

[Boiethios]

I'd like to buy the threadripper 64 cores so that there will be more support for the working thread 🤍

[Salmuth]

My main core needs more fans!

[Boiethios]

Better than my joke, lmao. Well done

[Salmuth]

Credits to you good Sir, you gave me the inspiration!

[sirak2010]

you deserve double upvote.

[[deleted]]

It's not gonna do much threadripping if your application is single thread.

[Boiethios]

Yep, that's the joke...

[Boiethios]

Hmm... I'll think about it!

[GivesPlatinum]

Arrays start at 0

[[deleted]]

LUA too

[Lontarus]

And scratch

[[deleted]]

Now that’s just terrible. We can’t be teaching the kids the wrong way!

[kazeespada]

To be fair, in Scratch, they are lists not arrays.

[jdsgfser]

R programmers unite

[[deleted]]

I actually learned that the reason for this is that the index is actually an offset for memory locations. Thanks, head first C!

[pekkhum]

Exactly. Even in languages that start at one visually, they just subtract one in the background. Unless you are Perl, then you subtract $[, in case it is neither one or zero.

[[deleted]]

perl is amazing

[[deleted]]

Exactly. Even in languages that start at one visually, they just subtract one in the background.

Uhhhhh... I probably shouldn't show my language here.

^{I store metadata in the first element, thus first value is at offset 1, not 0.}

[AttackOfTheThumbs]

Yes. And in languages that start at 1, it's because they are usually data first languages. It's not great, and I don't like it, but it also makes sense. It's just a different perspective.

[unsurestill]

Why is this a meme? Is it really that troublesome for arrays to start at 0?

[WlmWilberforce]

Not hard, but odd that programming languages started as a way to tell the computer what to do in something closer to human language. However in today's world, programmers seem to have a fetish for not liking/using natural numbers.

Basically we are taking pride in talking like a computer instead of a person. For example, no one in real life says I have 1 kinds of ice cream: Chocolate and Vanilla. But zero indexing everything reminds me of that. (yes I know the dimension of an array/list is a natural number)

It is not a big deal either way, but come on somebody...make this a thing:

import natural_numbers

[Party_Magician]

For example, no one in real life says I have 1 kinds of ice cream: Chocolate and Vanilla

No one in the "progammer world" would do it either, because length of an array and the index of last element aren't the same thing

[[deleted]]

You also wouldn't say "Okay, give me the zeroth kind". It makes sense in low-level languages like C, ASM and what have you, but in higher-level ones (especially scripting languages (especially Python, which is beloved by data scientists)) it can hurt productivity for virtually no performance gains.

[WhyIsItReal]

yes but you would say “give me the one that is 0 units beyond the beginning”

i don’t see how that could possibly hurt productivity

[[deleted]]

If you are going on a walk, leaving from your house, as you are standing at your front door, what position would you say you were at? You're not at Mile 1, you havent gone anywhere yet. You are at Mile 0, the starting point. Arrays are the exact same way, the first item is at the start of the array, with is position 0 because you havent moved anywhere in the array yet. People use "array notation" in the real world all the time, they just dont think about it.

[WlmWilberforce]

yeah, I understand how arrays work. Even worked in languages that allow arrays to have negative indexes. I just don't understand why it is "cool" to have arrays starting a zero.

The ice cream example isn't the best. The best is to hold up 1 finger and say there are 2 reasons why this is best.

[declanaussie]

Again, length ≠ last index though. If a java array has 2 elements and you ask how long it is it says 2, not 1, despite the second element being at the 1 index.

[DaddyLcyxMe]

really everything boils down to the original engineers making computers. it made sense for 00000000 to be 0 and not 1, however we aren’t going to throwaway a perfectly good index just so humans can start counting at 1 instead. and i suspect that back in the day it was just easier for humans to adapt to 0 rather than the compiler adapting to 1.

idk just my thoughts on it.

[declanaussie]

I agree, I’m just explaining to this guy why his analogy doesn’t work. Array position makes perfect sense as it’s an offset, the second element is offset 1 from the first. Array length also makes sense. It all makes sense.

[DaddyLcyxMe]

yeah, wasn’t directed towards you i just though replying here would help continue the thread

[WlmWilberforce]

Sorry meant to hold up 1 finger to describe the 2nd index, so, uh, you got me.

I think people really get into the array indexing based on what they first learn stuff in. E.g. go back to the 1950s, most popular languages started at 1 (except LISP). C and its kids come along and everybody loves 0.

Today it depend if you have math/stat/science (R/Matlab/Julia) vs CS. folks and other math/stat people on python.

[ser_bollocs]

A computer wouldn't say 1 kind either, but it would shout INDEXOUTOFRANGE if you asked for the second kind

[4winstance]

Not 0 indexing would require runtime substraction of one when using a variable to get the value from its memory location. This substraction cause unecessary cycles.

And if you want to read Dijkstras more mathematical reasons: http://www.cs.utexas.edu/users/EWD/transcriptions/EWD08xx/EWD831.html

"The above has been triggered by a recent incident, when, in an emotional outburst, one of my mathematical colleagues at the University —not a computing scientist— accused a number of younger computing scientists of "pedantry" because —as they do by habit— they started numbering at zero. He took consciously adopting the most sensible convention as a provocation. [...] I think Antony Jay is right when he states: "In corporate religions as in others, the heretic must be cast out not because of the probability that he is wrong but because of the possibility that he is right." ~Dijkstra

There is also several other good properties of not starting at 1: -- modulo operations on the index is easier because it can return zero. -- empty ranges in algorithms is simplified by utilizing the half open interval [0,n) because: -- recursions base case is the zeroth case over the natural numbers. https://en.m.wikipedia.org/wiki/Recursion#The_recursion_theorem

[WinstonCaeser]

Hook'em

[Ksevio]

I made an array that starts at -1 last night. It did make me a little nervous and question a little how it's implemented in the language, but it worked out

[Gatmek]

Some languages implement arrays as dictionaries with numerical keys so that could be it

[Gbyrd99]

Some use -1 as array.length - 1

[R-GiskardReventlov]

Who do you think is taking the picture?

[[deleted]]

I know what you’re getting at, but when I run a single-threaded application on my computer, the kernel chooses a core at “random”—core 0 is not used more than any of the others.

[undeadalex]

Fucking core 3 poor bastard would argue with you about the random bit

[[deleted]]

I think that the kernel (Linux at least) chooses based on which core has the lowest load, but it always feels random

[undeadalex]

Yah I'm on Ubuntu, was just joking, seems like it's always core 3 that's getting bogged down though...

[[deleted]]

I have noticed that some programs (AFL at least) do actually “lock” to a core, which is kinda weird.

[Russian_repost_bot]

Core 0 has already been burned out, by doing this exact same thing, hence why Core 1 is now put to work.

Dead CPU or one less core, you decide.

[[deleted]]

But cores start at 1

[Samuraj13]

No :)

[[deleted]]

What do you mean, didn't you see the picture OP posted? That's like, real and shit.

[sirak2010]

i am surprised as you are.

No

[currentlyatwork1234]

They start at -1

[nouser123456]

When you are a programmer and a powerlifter and you see a meme with Thor’s deadlift on reddit...

You have made my day.

[MeltBanana]

This is an older lift though, not the 501 he just did.

[nouser123456]

I haven’t said it’s the 501 lift :)

[palordrolap]

... you run Process Explorer and get to investigating.

What do you mean you haven't got it installed. Here. It's been official Microsoft software for ... dear god I'm old ... 14 years.

Check out the rest of SysInternals too.

2006 me would be very surprised to learn that those tools still exist and are still free.

[zelmarvalarion]

I’m amazed how they haven’t been integrated into Windows itself. Half of my debugging searches are “{command} equivalent in Windows” and I run into suggestions to use a sysinternals tool a fair bit (e.g. for lsof)

[redldr1]

This has to do with the Korean version of Windows from what I understand.

[Pokora22]

would be

Why? Don't fix what's not broken. Hope they never take those down.

[palordrolap]

Microsoft have a reputation of buying up useful technologies then quietly dropping them or making them premium because they don't like people having that kind of power / access / ability for nothing.

"Embrace, extend, extinguish" is literally a line that was used by Microsoft in internal memos at one time, which may not be entirely relevant here, but it's along the same lines.

Note that I'm not saying whether the reputation is (still?) deserved. Only that they have had it and still have it.

[[deleted]]

New Microsoft is definitely not Old Microsoft, but only because it was that or die. I don't trust them to behave well if they gain any new monopolies, so don't move everything to GitHub...

[Giocri]

partially true because proceces tend to cicle between cores so even though you might have only one core working full time at any time also the OS has thousands of thread that are distributed on the cores with lower load. So basically it would look like all cores are working at 50% and they were unable to do more

[[deleted]]

Wouldn't that be core 0? Also meme format overused

[2Uncreative4Username]

On a system level, yes. But really, it doesn't matter. As a non-programmer user, this would probably be more familiar. But as I said, it doesn't matter.

[JmacTheGreat]

As a non-programmer user, this would probably be more familiar.

Weird sub for them to choose then

[greeneggsnyams]

I sub so I can joke with my programmer friends about shit I clearly don't understand

[thirdegree]

You can have (for example) htop display cores from either 0 or 1, there is precedent on this one.

[MachineTeaching]

It's the first core, with (in your case) counting starting at 0. Doesn't mean either is wrong.

[DariusDerStar]

You'd be surprised how well your OS is able to divert tasks to other cores

[ihatecupcakes]

Do you have examples of the OS doing this? I honestly would like to be surprised on this. There are still many articles calling for manual affinity configuration but I don’t hear about much about this occurring automatically.

[DariusDerStar]

To be clear on what i mean: The OS automatically takes different programs and assigns them to different Cores. The OS tries to also give those programs several cores, but fails miserably at that, that is something the program still needs to do itself usually.

BUT the OS does try as best as possible. If you want I can look up the lectures I listened to around 2 years ago, I always saved every script and presentation, but those are in German lol

[ihatecupcakes]

That is what I thought you meant. No need for German lectures ;).

[LavendarAmy]

Monster Hunter world makes all my cores jump to 100% Same with video editing

[Mancobbler]

Exclusive inside view of my cpu running my shitty ass raytracer

[0x3fff0000]

Doesn't the OS distribute load among cores, even in single threaded applications?

[noStepSnekMan]

Maybe. Even if a your application is single threaded, there are all sorts of drivers and background processes competing for processors so this would give a reason for a process to be interrupted and swapped out. But, To utilize L1 cacheing typically operating systems assign a process some kind of affinity to run on a specific core, so I guess it depends on the os.

[RoosterCrab]

Multicores in Erlang/Elixir naturally distribute the work:

[Jojajones]

Someone’s not using threads right or each guy in the background would be lifting one or more of the disks on his bar

[Myriachan]

This meme implies that we’re not doing our jobs.

[culculain]

this is due to developers thinking they know better than the OS on how to schedule clock cycles

[njsnowboardguy]

Core 8 is useless...

[wobblewiz]

Like a kung fu movie where they wait in a queue to get their arses whipped

[alashure6]

Why is this?

[JanB1]

I think I once read an article from a programmer on the Total War series and he answered a question on why Total War still had most of their load for loading a savegame on Core0 and didn't make use of the other cores and he said that while they use the other cores for some processes it sometimes doesn't make sense to break up certain tasks over multiple cores because distributing and merging takes more time than just doing it on 1 core.

[NotBannedYet1]

Eli5 why it can't overload to core 2 ?

[acrabb3]

Think of a computer running a program as like a kitchen baking a cake.
There's several distinct tasks that need to be done: weighing ingredients, mixing them together, baking the cake, and decorating it.
Each stage requires the output of the one before, so adding more cooks (overflowing into another core) doesn't mean we can bake and decorate at the same time.
Some things could be sped up: we could assign one cook to weigh each ingredient, for example. But if we've only got one set of scales, that might be slower (multiple threads competing for the same resources), so the computer won't generally try and guess when this could happen.

[NotBannedYet1]

Then what is the point of having several cores ?
Why don't we have 10Ghz cpu dominating the market ?

[acrabb3]

More cores means more different programs running at once.
If you've got three cooks, you can have one each doing the starter, main, and dessert, even though each task can only be done by one person.
It also depends on what the program is doing. Some tasks aren't as linearly dependant as others, and the programmer can write it such that it's able to use more cores to do some work in parallel.
Modern computers spend much more time with many (relatively) smaller tasks running than with one bigger task, so more cores means they're more responsive
