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.

๐Ÿ˜‚ Trueee! โ€œDELETE FROM users;โ€ is pure horror-movie-level code.
But yeahโ€ฆ git reset --hard HEAD~1 โ€” thatโ€™s psychological horror.

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

}catch(e){
this.toast.error('Something went wrong!'); // who knows what went wrong ๐Ÿซฃ

Every developer has that one โ€œtemporary fixโ€ still haunting production โ€” mineโ€™s a console.log buried so deep Iโ€™m scared to delete it now.
Love how you turned cringe moments into a growth reminder โ€” itโ€™s the perfect Halloween post for devs ๐Ÿ‘ป๐Ÿ’ป

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' โ€” because apparently '-e' means edit and '-r' means nuke everything, no prompt. :-D
