DELETE FROM users WHERE location = 'IRAN';

Hi! I am an Iranian Software Engineer, and in this torn paper note, I want to talk about some funny moments I had online related to the fact that I was spawned in this specific region of the world: Iran.

Microsoft deleted my app, ignored my mails

Back when I was a student, I got access to the Microsoft Imagine, and as a result, I got access to the Microsoft Store as a developer. This inspired me write one of my open-source projects called EyesGuard and publish it on Microsoft Store. However, one day, somebody told me that they can no longer find EyesGuard on the store.

Ubuntu LTS on MacBook Pro 2017 (A1707, MBP 14,3)(T1 chip)

Summary

Notes to install Ubuntu 22.04.4LTS (Upgraded to 24.04LTS) up and running on my 2017 MacBook Pro 15 inch (MacBookPro14,3).

Now everything except the TouchID (Fingerprint), Suspend and Hibernation seems to work for me.

About Ubuntu 24.04LTS: I tried to install Ubuntu 24.04 and didn't have success. There was a crash issue during installation. https://bugs.launchpad.net/subiquity/+bug/2065310 But I installed 22.04 and upgraded it to the 24.04LTS later and it working same as 22.04.4.

Git clone using ssh agent forwarding and sudo
SSH agent forwarding is great. It allows you to ssh from one server to
another all the while using the ssh-agent running on your local
workstation. The benefit is you don't need to generate ssh key pairs
on the servers you are connecting to in order to hop around.
When you ssh to a remote machine the remote machine talks to your
local ssh-agent through the socket referenced by the SSH_AUTH_SOCK
environment variable.
So you the remote server you can do something like:
