It’s rare in software development to stumble upon something that completely redefines the way you work — something that turns a tedious task into a fluent, almost effortless process. For me, GitHub Copilot was exactly that kind of revelation.Let me say it plainly: this tool is nothing short of miraculous. For just a couple of dollars a day — about the price of a coffee — you essentially hire the most focused, knowledgeable, and fast-moving junior developer you could ever dream of. Except this one never sleeps, never complains, and responds to your intent before you even finish typing.

Since the advent of GPT‑3’s code‑centric descendant "Codex" in 2021, OpenAI has consistently advanced the art of AI-assisted programming. Originally powering GitHub Copilot for inline autocomplete in editors like VS Code, the new Codex agent unveiled in May 2025 marks a decisive leap—it acts as a cloud-hosted software engineering agent that autonomously tackles entire tasks, not just code snippets (en.wikipedia.org, devops.com).

Spam, phishing, and spoofing are rampant, leading to lost productivity and security risks. To combat these threats, a trio of essential email authentication mechanisms has emerged: SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance).
