`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.

How to correctly use a hardware random number generator (hwrng, trng) on Linux 5+ (Debian 12+)

Problem

Linux entropy pool doesn't know about external, non-default, non-driver entropy sources.
Modern Linux usually reports 256 for cat /proc/sys/kernel/random/entropy_avail. This has to do with the entropy pool rewrite sometime ago that prevented blocking of /dev/random.
There is presently no userland entropy pool seeding "pull" mechanism.

Solution

set -e, -u, -o pipefail

The "set" lines These lines deliberately cause your script to fail. Wait, what? Believe me, this is a good thing. With these settings, certain common errors will cause the script to immediately fail, explicitly and loudly. Otherwise, you can get hidden bugs that are discovered only when they blow up in production.

set -euo pipefail is short for:

set -e
set -u
