Btrfs snapshots?

CCF_100 ,

You're using btrfs on prod?!

Man, you're crazier than I thought... /s

Oh shit that was too controversial, wasn’t it?

What is right clicking on terminal going to do?

KpntAutismus ,

maybe they have it mapped to enter, you never know with laptop linux users.

Droechai ,

Right click increase the temp of the touchpad, which the user has macroed as an "Enter"input, letting him press enter with all fingers on home row and just resting the palm on the touch pad

MeanEYE ,
@MeanEYE@lemmy.world avatar

Ultimate ergonomics at the cost of entry speed.

CookieOfFortune ,

Hmm I thought you only spin once so there’s eventually a guaranteed shot. The 6 should decrement after each execution.

Lifter ,

That's not how randomness works. You would want to randomize once, saving the number of steps remaining until the bullet is the next shot, decrementing the number of steps for each try.

Fun fact there was a guy a little over a decade ago who got drunk and traded 7m barrels of oil futures. Not dollars, barrels. He made the price of oil jump up for a short while.

https://www.theguardian.com/business/2010/jun/29/drunk-oil-trader-banned-fsa

DAMunzy ,

Funnier Fact: they had to stack all those barrels behind the corporation's building until they could sell them all.

::I made this up::

fogstormberry ,

the best source

DAMunzy ,

Artisanal sourced. With an emphasis on anal.

Empricorn ,

Does that butt have any other fun facts up there?

DAMunzy ,

The roller coaster was invented during the Hundred Years’ War as a way of launching supplies across rivers.

Disclaimer: I'm stealing these fake fun facts from other people.

@possiblylinux127@lemmy.zip avatar

Actually a oil future is basically a promise to make oil for a certain price. There are also are vegetable futures

That means the oil wasn't produced yet

DAMunzy ,

I know. I was just joshing and tossing fake facts around. 😉

milicent_bystandr ,

But I do remember a story (on daily wtf) where a lady bought coal futures and somehow forgot or didn't manage to sell, and a coal barge turned up in the river behind her office!

FiniteBanjo ,

Also, Crude Barrels have a shelf life so you definitely wouldn't store them like that for any extended period of time.

possiblylinux127 ,
@possiblylinux127@lemmy.zip avatar

A future means that they will be created at some point in the future. Basically its an agreement to buy for a certain price in the future regardless of what the markets are doing.

FiniteBanjo ,

Yes you said exactly that in the comment I replied to, I never argued against it I was just adding onto it. We both were talking about how unrealistic the comment further above yours was.

faintwhenfree ,

Well he was 69% of all traded volume..... nice!!

Isn't that wild?

GravelPieceOfSword ,

Cowards version:

[ $[ $RANDOM % 6 ] == 0 ] && echo 'rm -fr /... you crazy dude? NO' || echo 'Keep your french language pack, you will need it'

ordellrb ,

Does "rm /" include external drives under /media/$USER/* or /run/media/ ?

Emerald ,

Yes

OsrsNeedsF2P ,

Obligatory --no-preserve-root

DAMunzy ,

Modern distros today. SMH. Back in my day everyone had root at the office.

mitchty ,

On ye olde hpux this would work, especially when you did rm-fr /$var and $var was unset and nobody unit tested their shell back then. That db server ran for 2 days though with open file handles before it finally died.

Scene : 1998, Fort Bragg 18th Support Something-or-other, IT department

Date: 11th day of the month sometime before summer. Let's assume May.

Young Specialist looks at wall clock. Looks at time on the system. "I can fix that!"

Should I man date first? Fuck that, let's just do it!

Proceeds to set the time in the HP Unix minicomputer that handled all supply orders for the non Special Operations side of Fort Bragg.

Oops, set date to November 5th but with the correct time. No problem, we'll just run that date command again and flip the 5 and the 11 around. All fixed! Back to May 11th.

Comes into work the next day wondering why everyone is running around like crazy. All the processes have kicked off and are waiting for November to run again.

Ut-oh. Comes clean to NCOIC.

Aftermath: root was taken from all junior enlisted (good move) and only Staff Sergeants and above had it l. Oh, also the outside IT professional/Army civilian I assume.

Young Specialist gets written counseling (which was bullshit BTW- I made an honest mistake) and not UCMJ supposedly because I was going off to Kuwait for PCS (Permanent Change of Station) soon. Not allowed back on system.

Disclaimer: might have happened in June but either way I'm pretty sure I set the date to November and I know I got the date command order wrong at least once.

mitchty ,

Jokes on you, I use zsh, your silly bashisms have no power here.

vox , (edited )
@vox@sopuli.xyz avatar

fish and nu are the superior shells

mitchty ,

Is fash like that fish shell only more fetch? zsh is obviously the best, its the omega end to shell names with the z (in latin alphabets so there).

vox ,
@vox@sopuli.xyz avatar

yeah i meant fish

palordrolap ,

Are you sure it doesn't work on zsh? It's valid POSIX shell code, and like bash, zsh is a superset of POSIX, at least if I remember correctly.

This is not to goad you into destroying your filesystem. Replace the rm with something relatively harmless like echo "BANG! You're dead!" if you decide to test it.

mitchty ,

Key here is the outer [] and interaction of $[], test doesn't have == by default in standard posix, so no this isn't posix shell or bourne compatible. Tis but another bashism. I could probably force zsh into a more bourne mode to try it but its definitely not portable bourne shell its bash.

$ [ $[ $RANDOM % 6 ] == 0 ] && echo rm || echo ok
zsh: = not found
$ zsh --version
zsh 5.9 (x86_64-pc-linux-gnu)

== should be -eq for this to be posix/bourne portable, you could use = but -eq is for numeric comparisons so not quite right.

Artyom ,

This is why you use virtual machines, anyone can be root!

possiblylinux127 ,
@possiblylinux127@lemmy.zip avatar

Or just to have a modular, secure and private system.

Klear ,

We are root!

Nollij ,

This really isn't dangerous unless you already screwed up badly. If it wipes, you just restore from backup/DR.

You do have backups and a DR plan for your prod servers, right?

sheogorath ,
MystikIncarnate ,

Same.

MigratingtoLemmy ,

Not sure, do I?

Zorsith ,
@Zorsith@lemmy.blahaj.zone avatar

Sure do! They're on the prod servers and were one of the first things deleted!

Inktvip ,

Didn't some company have a script running that would randomly kill stuff to always test redundancies?

I vaguely recall someone telling me that about netflix

Edit: https://github.com/Netflix/chaosmonkey

mossy_ ,

that's like starting fires on random properties to make sure your firefighters stay on their toes

scarilog ,

Ferb, I know what we're gonna do today

boeman ,

I vaguely remember reading a news story about a firefighter that did that a while ago.

Pika ,

the backup was connected via /media/backups so that's gone too!

Andrew15_5 ,
@Andrew15_5@mander.xyz avatar

There is a $[]?

Morphit ,
@Morphit@feddit.uk avatar

Huh, it's the same as $(( )) - arithmetic expansion.
I think it's deprecated and not in the bash manual, but it still seems to work.

Andrew15_5 ,
@Andrew15_5@mander.xyz avatar

It is? Weird. I know about deprecated backticks, but this... I guess it's so deprecated that very few people know about this. Now a bit more.

comador ,
@comador@lemmy.world avatar

Daily Linux user since Slackware 95, news to me too lol

fmstrat ,

Same camp, and know bash very, very, well. Crazy how you can always learn.

lobsticle ,

As an old Perl jockey, you can pry my backticks out of my cold, dead hands.

mitchty ,

Its deprecated kinda like `` should be $() https://pubs.opengroup.org/onlinepubs/9699919799/xrat/V4_xcu_chap02.html seach for arithmetic expansion or $[].

smb ,
 HISTCONTROL=ignorespace
 unset RANDOM
 RANDOM=4
 clear
...

If RANDOM is unset, it loses its special properties, even if it is subsequently reset.

HISTCONTROL If the list of values includes ignorespace, lines which begin with a space character are not saved in the history list.

RTFM can save your server AND your bet ;-)

it is cheating of course if the predefined rules tell us about such requirements and if these are not met any more when unsetting RANDOM ahead of it.

librecat ,

Given that their hand is over the mouse and not the keyboard/enter key, I assume they're gonna click close on the terminal :p

mipadaitu ,

Right click for paste, they have \n in the clipboard

mexicancartel ,

Afaik \n may not run a command. I have pasted multiline commands but they only seem to run after hitting enter

Ghoelian ,

Depends on the terminal I think. Pretty sure KDE's Konsole warns you that commands may be run when pasting something with newlines, but still allows it.

LostXOR ,

It definitely runs the command for me in GNOME Terminal. Pasting multiple commands at once runs everything but the last command.

MeanEYE ,
@MeanEYE@lemmy.world avatar

There is an exploit which addresses copy pasting things in terminal. Where you'd copy one thing, but when pasting you get more than you bargained for. Any decent terminal would ignore \n for this reason or at least not treat it as pressing enter.

nebula42 ,
@nebula42@lemmy.today avatar

Well they did have the type the command, and to do that they would first have to navigate to the terminal (assuming the machine isn't running just a plain tty) first.

SpaceNoodle ,

root shell? Already playing it fast and loose, I see.

mlfh ,

The only legitimate commands for a non-root shell are sudo -i, exit, and echo "yee haw"
