[Imposter syndrome] Back to the beginning (DevSecOps path)

A developer spent nine months building a Python port scanner from scratch, manually assembling raw sockets and TCP packets to understand every underlying principle rather than using libraries like Scapy. The project, named SharkTooth and available on GitHub, involved studying RFCs, network byte order, and SYN scanning mechanics, with the developer refusing to copy code without full comprehension. The engineer has since paused the scanner to write a Python backup script, citing health issues and a need to reinforce foundational Python knowledge.

I’ve been writing my project - Python port scanner for 9 months now.

You might be wondering, “Why is it taking so long?”

Most of the time was spent figuring out how raw sockets work, how to write a function for manually assembling a packet, calculating the checksum, packing the IP packet bytes, the TCP header, the pseudo-header using struct.pack, sending the packet, and how SYN scanning works.

Why did I decide to take such a complicated route instead of just using Scapy?

I’m a principled person and have a very exhausting yet useful skill—understanding everything. That’s how I got acquainted with big-endian, or “network byte order.” I won’t go into the details of big-endian logic, to be honest, I’m already mentally exhausted

It took several evenings and nights to analyze and understand the principles—watching videos, reading RFCs, and looking at GitHub code (which I didn’t understand)—but what bothered me most was that I had to ask gemini for an explanation.

As I mentioned above, I’m very principled; I can’t just copy code without understanding it, so I ask gemini for a prompt like this: “Don’t write the code for me. If I end up asking you for an example because I’m tired, explain it line by line.”

Yesterday I realized I don’t fully understand Python (basics)—I don’t remember REPL—so I went to ask Gemini for advice; I don’t have anyone competent who could help me with advice. I’m not very sociable, and the only thing that’s interested me for the last four years is IT. I used to make music.

Lately, something strange has been going on with my health, the day before yesterday I woke up because of a nosebleed; this has happened before, but on a larger scale.

I stopped working on the scanner yesterday and decided to try writing a backup script in Python. I found an article and jotted down in Obsidian what the project should and shouldn’t do.

Previously, the project used Docker, Prometheus, and Grafana.

My questions:

P.S. Thanks in advance for your answers; I appreciate them. I’ll make one embarrassing confession—sometimes I wanted to show my emotions, but I suppressed them, which I do from time to time
