1. Introduction In networking, OSPF (Open Shortest Path First) is a routing protocol that ensures traffic flows along the shortest and lowest cost path through a network. It does not care about hierarchy, seniority, or intent. It routes based on capability, cost, and reliability. Modern engineering organisations behave in exactly the same way, whether they […]

When combined with Claude through the Model Context Protocol (MCP), it becomes an even more powerful tool, allowing you to leverage AI to intelligently analyze scan results, suggest scanning strategies, and […]
Read more →Prepared statements are one of PostgreSQL’s most powerful features for query optimization. By parsing and planning queries once, then reusing those plans for subsequent executions, they can dramatically improve performance. But this optimization comes with a hidden danger: sometimes caching the same plan for every execution can lead to catastrophic memory exhaustion and performance degradation. […]

Read more →Modern sites often block plain curl. Using a real browser engine (Chromium via Playwright) gives you true browser behavior: real TLS/HTTP2 stack, cookies, redirects, and JavaScript execution if needed. This post mirrors the functionality of the original browser_curl.sh wrapper but implemented with Playwright. It also includes an optional Selenium mini-variant at the end. What this […]
Read more →Modern websites deploy bot defenses that can block plain curl or naive scripts. In many cases, adding the right browser-like headers, HTTP/2, cookie persistence, and compression gets you past basic filters without needing a full browser. This post walks through a small shell utility, browser_curl.sh, that wraps curl with realistic browser behavior. It also supports “fire-and-forget” […]
