Field Notes

From the Trenches

These are raw, atomic notes captured directly from my daily work as a Senior Software Engineer. They focus on practical solutions, “gotchas,” and idiomatic patterns rather than polished theory.

Here is the archive of my engineering logs:

• Exception Mechanics: EAFP vs LBYL — Contrasting Python's event-driven exception model (stack unwinding) with Go's explicit value-based errors. Covers EAFP patterns, hierarchy strategies, and proper exception chaining.
• PowerShell String Interpolation & Quoting Guide (For Linux Users 😅) — One of the biggest friction points when moving from Bash to PowerShell is how strings are handled. While the logic is similar (single vs. double quotes), the syntax for escaping and handling objects is different.
• Provisioning Paradigms: Terraform, SDKs, & K8s Operators — A comparative analysis of state engines (File vs. Etcd) and reconciliation models (Edge vs. Level Triggered). Covers the engineering costs of custom operators, including Finalizers and dependency graphs.
• Exploring Match-Object in PowerShell — A introductory guide to Match-Object for Linux Users
• Injection Mechanics: Shell & SQL — Why mixing data and control planes is fatal. Secure implementation patterns for Python subprocess and Go os/exec.
