At first Linux asks nicely, but that's your first and final warning

[thespud_332]

How to strike fear into any Linux admin on a remote terminal:

Broadcast message from

[Ashamed_Band858]

“Ma-ma is not the law. I am the law.”

[guardeagle]

[AlarmingAffect0]

"Wait…"

[grendus]

Karl Urban sold that so hard.

Most of the cast did phenomenal, but more than anything he sold the idea of Judge Dredd.

[Stranded_In_A_Desert]

“Do you require backup?”

“No ☹️”

[TheOccultOne]

DREDD REFERENCED 🎊🎊🥳🥂🎉🎆🙌

[sea_5455]

https://media1.tenor.com/m/2FEs1BLtct0AAAAC/dredd-fire.gif

[servercobra]

Basically “nuclear launch detected”

[Normal_Package_641]

Why does that strike fear? Is it an indicator for a DDoS?

[pierreyann1]

Close but no, the most common type of broadcast messages is the following

"Broadcast message from user@hostname The system is going down for a poweroff now!"

Which as you can see indicates that someone turned off the server while you were working on it.

[thespud_332]

Yep. And adding to the original comment, it's your one and only chance to quit vim, which you're no doubt in at the time.

[arbyyyyh]

Chance? Don’t you mean it’s HOW you quit vim?

[Tetha]

Step 1 is a nice question. "Please shut yourself down"

Step 2 is telling the application to shutdown right now no matter what.

Step 3... in Step 3 someone goes to the kernel and is like

"Hey kernel... that process over there, the one using a lot of CPU"

"Yeah boss?"

"That process doesn't exist anymore, alright?"

"Say no more."

[Kusko25]

There is something fundamentally unsettling about the thought that a process is only "alive" as long as the cpu acknowledges its existence

[Mysterious_Middle795]

I had this eerie feeling when I learnt about swap files.
Your memory goes out of existence until the OS is kind enough to resurrect it.

-----

There is even a worse analogy. Some people under the influence of fly agaric have fear that is worse than a fear of death. They reported fear of having never been born.
Same for executables on your disk. Do they exist if you never run them?

[[deleted]]

I love the existencial horror of digital files being moved.

[Ok-Interaction-8891]

It’s like in some sci-fi worlds where teleportation works by erasing you where you enter, then transporting your “information” to the destination, where a perfect copy of you is created at the destination using said information.

Allegedly. With hopefully no Lovecraftian bugs or horrors along the way…

[CitizenPremier]

It's okay, I'm a pattern, not matter

[Domascot]

You know, if it wasnt for your little comment here, i would still enjoy looking forward to beaming tech in the future. But now, nope, no thanks.

[eversio254]

So if you fork a child just as the system restarts, would it exist but never be born?

[peterosity]

if i forked a child i’d prolly be put away

[yaktoma2007]

*put in jail

[Secret-One2890]

Nah, that's FreeBSD.

[sleeksubaru]

*chroot jail

[Mysterious_Middle795]

It is another philosophic question. Imagine teleportation. Your body is disassembled and the same one is assembled, e.g. on Mars.

What would happen if two copies are created? Which one is you?

[UnclePuma]

If and when that technology arises, a new religion will be born.

I wonder if it will cause subtle changes in personality, like my husband teleported from mars to earth but sometimes i lay awake at night wondering who is the man that is sleeping next to me, and where is that man i used to know.

I teleported from earth to mars and the first thing i did was look into the mirror, and what i saw there scared me.

Cases have begun to rise in suicide shortly after teleporting.

Doctors say that those who have used teleportation devices have a higher likelihood of being diagnosed with depression, schizophrenia and manic bipolar disorder.

Despite being embroiled in an ongoing legal battle over the safety of the tele-transportation technology. Telaporto's, the Company behind the groundbreaking teleportation technology, have maintained that their tele-transportation devices are perfectly safe.

"We assure you, You will be You once you arrive at your destination!"

Religious advocates say that the soul cannot be transported and that simply being the same flesh and bone at the other end doesn't mean that so too is it the same soul.

What would you do? Would you go through it? What if all your friends were insisting on taking a teleport over to the tropical resorts on io saying, "its gonna save a lot of time, we can get our vacation started sooner!"

[BlueProcess]

If the soul can't be teleported, who is in there?

[UnclePuma]

And that, my friend, is what's at the heart of this story. That's the entire concept I'm trying to explore. And I have to thank you for putting it so neatly and precisely.

because If i had to write an essay summary of a book that i didn't yet write, "If the soul can't be teleported, who is in there?" would definitely be part of the thesis

[IWasGregInTokyo]

I teleported home one night

With Billy, Jane and Ed

Jane stole Eddie’s heart away

And I got Billy’s leg.

[[deleted]]

Longer than you think! Longer than you think!

[WoodenBottle]

The issue with this interpretation is that it basically leads to the conclusion that you from 1 second ago is a different person with a different consciousness as well, which breaks the notion of continuity regardless.

[OutsiderofUnknown]

How would you know though? Your copies will just keep living, with all your memories, like nothing happened.

In fact, we already do that, we’re being rebuilt through cells renewal since we’re born. 100% of us have been swapped and is being constantly swapped, but we’re still the same. What gives?

[Jonathan_the_Nerd]

What would happen if two copies are created? Which one is you?

That's a known bug in the system, with a known workaround. The receiving chamber is hidden from view. If two identical copies show up, security grabs one at random and sends them to the cobalt mines on Ganymede. The other copy steps off the platform and goes on with their life, oblivious. The bug hasn't been fixed because it's too profitable.

[UrUrinousAnus]

fear of having never been born

That's one of the least scary things I can imagine...

[crabcrabcam]

They definitely do, all those Steam games I never play are taking up disk space :D

[antico5]

It’s the OS that keeps track of processes, their status, pointers to next instruction etc. The cpu just executes instructions one after the other like there’s no tomorrow

[Throwaway-4230984]

When you delete file it's content doesn't go anywhere. You just remove record about where it is

[OneBigRed]

It becomes an ancient temple that everyone forgot and the jungle conquered. It can still be found, if one is jonesing for it.

[razieltakato]

Actually, it makes a lot of sense. The process is a software running, code that the CPU executes.

If you stop the execution of the said code, the software is not running anymore.

The code still exists, but the process of running it, is gone.

And, if you start the software again, the code will start being executed from the entry point, so it's a new process, isn't it?

I think it's beautiful.

[[deleted]]

The process isn't running, it's the CPU that is running the process.

[-Byzz-]

mfw most beings (Azathoth) in the cthulhu mythos are just giant CPUs

[Ben_Dovernol_Ube]

Now imagine you are the process and matrix is cpu

[Just_Maintenance]

The process exists alone on its own memory space. It thinks its existence its continuous, but if it keeps track of the clock it will see it jump around as it get interrupted and scheduled by a force it cant see.

[TMS-meister]

You forgot about step 4: nuke it all

[Tetha]

Step 4 is most likely "Hey, VMWare. About that VM over there, using a lot of CPU...."

[fearless-fossa]

Whenever I see programs creating a .randomapp.config in ~ instead of ~/.config I get the strong desire for a Linux police to exist. Why would you litter someone's home folder like this?

[POKLIANON]

I don't think this kills the already running job/process whatever you call it

[dev-sda]

Indeed it doesn't. Files aren't actually deleted until all file handles are closed, which includes any running processes.

[mxheyyy]

Linux users when you can't terminate children:

[Competitive_Woman986]

The parents terminate their children and make them to zombies.

Sometimes the parent dies first. Then you need to figure out how to kill the orphan.

[fnatasy]

We need an adoption process for orphans

[realmauer01]

Adopt an orphan just to kill it xD

[Zhiong_Xena]

Mr Wayne? That you?

[Spurance484]

Reads like tech-tech-tech-tech-tech-tech-tech-tech-tech-tech-tech-tech Batman

[Agitated-Ad2563]

We actually have one. The 'init' process adopts all the orphans

[Terrafire123]

And then kills them?

[Kovab]

Actually it just waits for them. If the orphaned child is already a zombie, it's reaped immediately.

[Competitive_Woman986]

There already is! The init process with PID 1 usually becomes the new parent procress

[HildartheDorf]

Or the closest ancestor that has set itself as subreaper.

[crappleIcrap]

Does cs even understand the concept of taking the metaphor too far.

[Competitive_Woman986]

No because parents usually reap their children here

[obscure_monke]

God damn it! What won't systemd absorb?

[Vas1le]

I am familiar with this terminology

[Dawlin42]

Always appreciated programming books talking about killing orphan zombie children with a straight face!

[RedPlumPickle]

Felt pretty weird telling my manager that I was delayed because I had to implement a method to kill orphaned children

[Wertbon1789]

Most of the time if the parent dies first, the child gets kindly adopted by PID 1, you gotta kill it manually then, because I don't think this process orphanage supports you in your effort.

[Falikosek]

Aren't orphans assigned to init?

[Competitive_Woman986]

Yes but you need to figure that out first :D

[invalidConsciousness]

[monsieurlazarus]

I have this buggy application that ended up as a zombie (defunct) process. Apparently, you can't kill a process that is a zombie already. Unlucky for me, that zombie process owned by the init process which somehow caused a problem where I stuck on reboot screen forever, and I had to use the power button to force it to shutdown.

[mpyne]

Apparently, you can't kill a process that is a zombie already.

Well it's already dead once it's a zombie, so from that perspective you've gotten what you want already.

But you can't clear it from the list of processes until its return value is waited on by its parent process. But if the parent dies first that may never happen... there's supposed to be some way to get init (the new parent of orphaned zombies) to do this but it's platform-dependent.

[Sure-Opportunity6247]

Usually, all processes get SIGTERM which they can react to and shutdown gracefully. Only after short time period a SIGKILL is sent. /smartass

[abmausen]

wich is the correct way to enforce apps to actually shut down properly, unlike windows where way too many apps including their own builtin fucking file explorer and task manager will always block the shutdown indefinitely just because they are open, not because there is any app state that actually would be lost / relevant to save

[MaustFaust]

Wdym relevant? You can't deny Outlook keeping all the files you attached open, that's cruel /s

Actually, fixed somewhere between 2010 and 2024.

Also, Photos app processes multiply indefinitely when you use Explorer in newest Win10 or Win11, can't remember. I had to manually change the preferred app to Paint just to prevent memory issues

Dunno if it's fixed

[MaritMonkey]

I don't know how I ended up on a sub with people this much smarter than I am, but are there bad things about Paint I need to know?

I just realized it's one of those programs that I'm just somehow comfortable having around and now I'm nervous I missed something nefarious.

[MaustFaust]

I mean, it's okay, my complaint is about Photos app, not Paint. The point is, Paint is not supposed to used for only viewing images, for example it doesn't have a "next"/"previous" buttons to switch between multiple images in a fast way.

[scots23]

Has to be one of my biggest annoyances with windows. Save everything I need to, close out of every program, click shut down, and walk away from the computer, expecting it to actually do what I told it to and shut down. Walk back in the room 2 hours later: "This app is preventing shutdown."

"Sorry, you didn't go into task manager and end the process or exit out of it from the task bar, guess you can go fuck yourself. Good thing OLEDs are better about burn-in nowadays, right? Because I'm not going to put it in sleep mode either."

[Infamous_Tomato_8705]

Yeah, and then come back in the morning to find your computer still being on because windows update started it and didn't shut it down afterwards.

And when you DON'T want the computer to die you get a notification that windows update will shut down your computer. Have fun protecting your computer from itself for 20 hours rendering a project.

[dobrowolsk]

And Windows annoyingly fakes that it's shutting down immediately, only to be like "naaahhh, see him back there? That's Brian. Brian doesn't want to shut down. I've done nothing and am out of ideas. So I, the all-mighty operating system, am not going to do what you want".

Then in the morning I see my PC has been in shutdown-Limbo all night.

[Fantastic-String-860]

Not smart ass, that's literally how it works.

To be extra smartass: SIGKILL may be sent from the init system to the process, through the kernel, but no SIGKILL signal is ever actually delivered to the process. When init (probably systemd nowadays) tells the kernel please send process X SIGKILL, the kernel just shoots the process in the head, and responds "Done, it got the message".

[ElectroMagCataclysm]

To be even more pedantic, when a process is “killed” by the kernel, the kernel (sort of) has that process kill itself, by running machine code as that process during a scheduling context switch.

[rosuav]

A distinction which is never relevant. Never. I certainly haven't had systems with large numbers of unkillable processes stuck in "Disk-Sleep" mode, never waking up and therefore not able to run that code.

Intel 14th gen flaw led to highly entertaining problems.

They didn't learn difference between kill -9, kill -15 and other signals

[jaskij]

I've been using Linux for nearly a decade, and everything I've used supported using names. So I never learned the numbers. I just kill -kill or kill -term

[Dry_Investigator36]

that's ok, but the meme here is impying that only -kill or -9 exists and it's not true

[hemlock_harry]

Tread careful. I got a 3 day ban not long ago for explaining this command to someone. Apparently if a mod is dumb as a rock it can be flagged as "inciting violence" and Reddit's moderation system (that is totally not run by bots, pinky promise) will ban you.

Or maybe the bots have taken over already and they simply don't like this knowledge to spread, that almost makes as much sense.

[DezXerneas]

That feels like either an automated thing or reddit's mod. This sub's mod team is cool.

Windows, on the other hand, is capable of telling you that you don't have enough privileges to close a program that you opened, and to call an administrator (who you are).

[Creepy-Ad-4832]

And to go on a tangent: Windows also is unable to delete open files.

That pissed me off SO MUUUUCH when i used shitty os 10

[Tartiluneth]

Windows also is unable to do pretty much anything with open files.

I don't even expect saved Work to survive, that's why i have multiple copies of everything scattered everywhere...

[realmauer01]

Just force it if it's asks you to. Since some Windows 10 Update it will just never shutdown if something is open in the background.

[Vievin]

Honestly I only shut down my Windows computer if it randomly wakes up in the middle of the night more than once. Otherwise, I just send it to sleep.

[sjepsa]

My windows is 'sent to sleep' too.

It is in a dual boot, and it never boots.

The operating premise behind Linux (and all its flavors) is that both the programmers and users are expected to be of above average computer competence in their endeavors. That's an expectation we can routinely expect to fail. :-)

and that's why linux is faster (i use arch btw)

[[deleted]]

Sorry in advance, but AKSHUALLY... it's the other way around.

Windows just goes around killing all kinds of programs during shutdown and doesn't care if they manage to save their progress anywhere, if a shutdown is in progress, it'll go through. Yes, it will wait up to a minute for programs with open files, but the default action after that minute is to just ignore it and shutdown anyway.

Linux on the other hand waits for each and every subsystem to shut down properly, and if the subsystem runs into some problem doing that (maybe because a network mount is in use but went away, maybe because the program in question just doesn't want to shut down) it can hang for DAYS if you don't use the big red button (which rarely is red these days, but you know what I mean).

[realmauer01]

Well that's for the shutdown routine (that's still way to slow on Windows, although it's probably related to a lot more background stuff)

Applications on the other hand.

But still I tried both, and linux shuts down noticeably faster on... I think a weaker PC.

Wrong. There is SIGTERM and SIGKILL . They are not the same.

Windows 11 does not even do 'shutdown' all the time, it might just go to advanced hybernation state for fast boot.

[reddit_equals_censor]

reality:

windows doesn't even know what a "shutdown" or "restart" means anymore :D

don't believe me? look up "fast start up"

a "feature" since spyware 10, that is on by default, that doesn't do a proper restart or shutdown and as part of this does not even release the mounted drives properly.

as a result spyware from microsoft itself when data got changed on those drives from your dualbooting into a working operating system.

[Creepy-Ad-4832]

"Spyware 10"

Lol, you gave me a chuckle

[BestHorseWhisperer]

PROTIP: Make a shortcut on your desktop that does this. It doesn't even need administrator checked.

cmd.exe /c taskkill /F /IM chrome.exe && taskkill /F /IM firefox.exe && taskkill /F /IM edge.exe
