I was looking for DELETE FROM Users; or rm -rf /

I'm glad I didn't find them. But git reset --hard HEAD~1 is also pretty scary.

πŸ˜‚ Trueee! β€œDELETE FROM users;” is pure horror-movie-level code.
But yeah… git reset --hard HEAD~1 β€” that’s psychological horror.

I once wanted to do git rebase -i HEAD~4 and for some reason I wrote git reset --hard HEAD~4

For me it was :

try {
// very long code doing lot of stuff
}catch(e){
this.toast.error('Something went wrong!'); // who knows what went wrong 🫣
}

For me, it was SELECT * FROM dbo.HugeTableWithoutIndexes WHERE DATEDIFF(DAY, ADateColumn, @AParam) = 0 Boom! A server on fire and users calling!

Haha this hit way too close πŸ˜‚
Every developer has that one β€œtemporary fix” still haunting production β€” mine’s a console.log buried so deep I’m scared to delete it now.
Love how you turned cringe moments into a growth reminder β€” it’s the perfect Halloween post for devs πŸ‘»πŸ’»

At this point it’s not debugging, it’s a stability ritual
Thanks for the love! πŸ‘»πŸ’»

Sometimes I try to find the formula for calculating a percentage, and I write a comment for the rule of three, like this

// a 100%
// b x
// x = b * 100 / a

I'm not very proud of having to write it down so I can visualize it

You can still recover from 'git reset --hard HEAD~1' with 'git reflog'. Now try 'crontab -r' β€” because apparently '-e' means edit and '-r' means nuke everything, no prompt. :-D
