Uber Eats is acquired by Zomato🙄

Nowadays, for me... Reinstalling the apps makes the apps to run faster...Lol

In a server, we are using mail client as Postfix...the mails are stuck in the mail queue and I have cleared mail queue using the "postsuper -d ALL deferred" but the mails are reappearing after the deletion of mails in a queue...
I have tried to restart the services..but it is still reappearing in a queue....

How to resolve the issue once and for all...

What are types of load issues occurs in a Linux (Cent os) server and it is troubleshooting methods???

WTF with Uber Eats. Finally I had some amount left in my salary. I ordered food via Uber eats and they charged me. After sometime they restaurant not accepted my order and cancelled it. I paid for and I don't have an extra money for ordering. The repayment says it will repay in after 7 days. After Contacting customer care number, it is only priority for the ordered customers only. I'm starving now...Fuck this morning and Uber eats. Any devs from that shitty company take care of that flaw...they are taking this as a fucky business...
What a flaw...taking is faster and repayment takes 7 days...
Seriously out of my mind....fuck...fuck....

Just explain me how to get over the fear on programming...I got a lot of resources but i too feared on programming while seeing the question???
