My Friend: Dude our Linux Server is not working anymore!

Me: What? What did you do?

My friend: Nothing I swear!

Me: But you were last on it?

My friend: Yes. I just wanted to run a bash file and needed to give it permissions.

Me : WHAT DID YOU ENTER???!

My Friend: Chill man, just this command I found on the internet
chmod -R 600 /
chown -R root:root /

Me: WHY ARE YOU EVEN IN ROOT AND GOD DAMMIT WHY ARE YOU EVEN USING SOME RANDOM COMMAND FROM THE INTERNET. YOU KNOW YOU SHOULD NOT DO THIS OR JUST ASK!

My friend: Ok I did something wrong, how can I fix it?

Me: Did you make a backup or rsync of the server?

My friend: No. I just wanted to run this file.

Me: You holocausted the server. FUCK MY LIFE

Permissions in Windows

Difference between chown and chmod 777 explained in one picture.

Now, I work at a hosting company in the UK, as a linux support engineer. I've seen many cases where a number of clients ran one of the following:

rm -rf / something
rm -rf /var/cache (attempt to magento)
chmod 777 /var
chown -R user:user /*

Half the time, they're like "Hey guys, I dun did fuck up, please help!". The other half of the time, they piss me off. Here's a number of responses that really grinds my gears:

"Such a harmful command should really prompt for input before running" -- From the buy you "forced" a recursive rm command, which mutes such a feature.

Client: "I did no such thing"
Me: "I've seen the command history, and at the time the command was run, you were the only person logged in"
Client: "You're mistaken, You're reading the information wrong"
Me: "I assure you, I'm not, I know what I'm looking at"
Client: "Well you're a shit engineer"
Me (thought): "Says the fucker who doesn't know how to linux"

I like people who own up to fuck ups. But the ones that don't, are just making their lives harder, since we have all the evidence in front of us.

Most of these people are the developers, and in some cases, the sysadmins...

sudo chown tux:tux ironthrone

N e v e r, fucking e v e r chmod/ chown permissions recursive on the linux /etc folder❗

I did yesterday (, because I am fucking dumb and know little about linux systems) and got the result today. My whole mailserver wasn't working.
After fucking tons of googling and searching and log-digging I found that postfix and opendkim require specific permissions on their respective folders and files.

After changing a fucking amount of permissions on those fucking files the fucking mailserver worked and I can send and receive mails, now. 😤😤😤

What a torture. Lesson learned. Never will repeat this mistake.

😅 What's your thought on introducing abstraction early?

Sudo chown / indead of ./ aaaand there goes my day.

Good Visualisation.

Intended to type
sudo chown -R name:name ./*
Instead typed
sudo chown-R name:name /*

I previously worked as a Linux/unix sysadmin. There was one app team owning like 4 servers accessible in a very speciffic way.
* logon to main jumpbox
* ssh to elevated-privileges jumpbox
* logon to regional jumpbox using custom-made ssh alternative [call it fkup]
* try to fkup to the app server to confirm that fkup daemon is dead
* logon to server's mgmt node [aix frame]
* ssh to server directly to find confirm sshd is dead too
* access server's console
* place root pswd request in passwords vault, chase 2 mangers via phone for approvals [to login to the vault, find my request and aprove it]
* use root pw to login to server's console, bounce sshd and fkupd
* logout from the console
* fkup into the server to get shell.

That's not the worst part... Aix'es are stable enough to run for years w/o needing any maintenance, do all this complexity could be bearable.

However, the app team used to log a change request asking to copy a new pdf file into that server every week and drop it to app directory, chown it to app user. Why can't they do that themselves you ask? Bcuz they 'only need this pdf to get there, that's all, and we're not wasting our time to raise access requests and chase for approvals just for a pdf...'

oh, and all these steps must be repeated each time a sysadmin tties to implement the change request as all the movements and decisions must be logged and justified.

Each server access takes roughly half an hour. 4 servers -> 2hrs.

So yeah.. Surely getting your accesses sorted out once is so much more time consuming and less efficient than logging a change request for sysadmins every week and wasting 2 frickin hours of my time to just copy a simple pdf for you.. Not to mention that threr's only a small team of sysadmins maintaining tens of thousands of servers and every minute we have we spend working. Lunch time takes 10-15 minutes or so.. Almost no time for coffee or restroom. And these guys are saying sparing a few hours to get their own accesses is 'a waste of their time'...

That was the time I discovered skrillex.

Accidentally (SOMEHOW):

sudo chown <user> -hR /usr/bin/

Tries to run "sudo su" after 12 hours:

sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set

it was at this moment that he knew, he f'd up

Rejected by a woman I liked very much. 🙂

Daily Standup with HR... what the f**k is going on..? 🤨

"chown -R randomuser /*"
Yes because I'm a dumbshit for not typing ./*

I thought living alone without my family will help me to be more productive but no! When I got out of the office and start walking towards my home, I feel like there is no one waiting for me. What am I doing? When I reach, I feel empty, all alone, by myself. Maybe, it's time to marry someone, maybe a girlfriend? But I don't have any courage to start a conversation with a woman. I just expect someone will talk to me out of interest. But none! Is marrying someone the only solution? having a family is the ultimate peace? IDK

Alas!!!

Fuck all authentication everywhere all the time. Fuck your passwords. Fuck your fingerprints. Fuck your rolling key fob. Fuck your aws secrets. Fuck your docker secrets. Fuck your oauth. Fuck your /etc/passwd. Fuck your groups. Fuck chmod and fuck chown and definitely fuck Kerberos. Fuck Saml. Fuck duo mobile. Fuck rotating pins. Fuck axiad. Fuck selinux. Fuck your fill out this form to get role based access. Fuck it doesn’t work because you can’t log in. Fuck it.

Working from home chair

Trying to refactor legacy code can be a real adventure. It's like exploring an ancient ruin, except instead of hidden treasures, you're uncovering cryptic code and dead ends. But the real plot twist comes when you realize there are no unit tests to guide you. It's like trying to navigate a maze blindfolded - you never know when you're going to hit a dead end and end up with a headache! 🤯

I am unable to learn Docker & Kubernetes yet. It's been 3 years I am working as a backend engineer. 🥺 I don't know why I find it hard to grasp those.

seriously? 🤔

Is there a limitation of how much I can commit in git each day in a separate 'feature-branch'?

Cause, I had to explain to a team member (somewhat senior than me) why I committed 9 times in a single 8 hours task(s) (according to him where it was two separate tasks done in a single day).

When I said, I prefer to save my progress in a small commit (at least try my best to write meaningful commit)", I turned out to be a stupid team member. 😔

I think - programming is not for me. :(

How to be a good programmer? 😔

The ability to ssh to an Earth terminal.

chown -R sionc /socialmedia/facebook
chown -R sionc /alphabet

I would then have the resources to do way bigger projects. Elon Musk can keep his businesses though. I like Elon Musk.

I'd maybe chown my company too, just for fun.

I'd ping my fiancé everytime she goes in a mood and ignores me for half an hour. She'd have to respond and it would annoy her. :3

userdel could be used on the bad people. >:)

There's probably a whole list of these that I've not even thought of that I'll see people write in the comments. I'm pretty sure this could get dangerous.

Executed chown -R www-data:www-data /var/www on my server without even thinking.

Not long after I panicked for a few seconds while checking if everything was still working. I didn't know if this command would break stuff or not.

So glad all websites are still working.

Now I'm sitting here thinking: was I braindead while executing the command??

All I wanted to do was set the right permissions for certain folders because images couldn't be uploaded with PHP.

What to do as junior, if multiple seniors (4) aren't in sync with each other. Following different convention on same client's project. Even after 3 years they didn't able come up with seemless infrastrure. The code is getting ugly day by day. No review happens. Is that normal? As they are not in sync, we, juniors are frequently getting confused what to do. What could be done? I'm planning to leave the project somehow. Don't know what to do. 😑

How do you deal with your juniors when they do any mistakes? Do you praise them when they overcome any challenges they were facing? Do you blame them rather correcting them? Do you balance both praise and blame to them? Just curious. 😅

Why? As a senior, you won't give some time to review my code, will let me merge my code to a branch, then blame us when it will produce the bug in production? why? 😐 Won't even arrange a code review/knowledge sharing session so that juniors can learn at least something. Even you won't encourage us write test cases. If seniors don't follow, are the juniors to blame? 🙂

Is it called C-H-own or chown (like down with a ch)?

Are there any risk in running Duel Boot (Windows 7 & Ubuntu) at the same time? Are there good tutorial you can provide? I wanna be linux guy. Kinda confused!

Just got into a chown mishap, all that took was a typo space between / and rest of the path, now i can't sudo anymore 😭

What is your best sudo story?

Did you get any seniors like these... we need to do that and that but tomorrow I won't remember and do as I told. 🫠 He won't wake up until any production bug arises.

Sometimes I feel like I can achieve everything in this very moment, sometimes, I'm like "meh! why do I exist? why I'm working that hard." 🥴

AWS or Digital Ocean?
What will be the best choice in case of costing as well as managing by single developer? 😅
I'm having difficulty to choose one for a long-lasting project of mine. Kindly, your suggestion with explanation will be helpful to me.
Technology: Spring Framework
Thank you.

Learning how to build micro services using Spring Cloud. As I'm not familiar with this architecture, the company's lead engineer suggested me to do research & development on it, recommended me to follow official guide lines before involving me to the current under development project.

What's your advice regarding - what to keep in mind while learning micro service architecture (could be in one sentence)? It will be helpful to me. ^_^ Thank you.

ChatGPT made my life easier! 😌
Now I'm the 10x Developer LinkedIn People talked about. 😎
Though I didn't find Bard as responsive as ChatGPT! 🫠

My first working code added to the office's project's codebase. It's really an amazing feeling to see my written code along with other dev's code. The senior developers were very supportive and helpful. There is a lot to learn. 😁

Been using Linux since 99' and only just now discovered chown --reference can be used with . so you can fix janky folders in a jiffy.
