Every post since has used readable, human-written code. This is the post that bridges that entire gap — lexing, parsing, compilation, interpretation, and the bytecode-plus-VM hybrid approach that Python, and much of the modern software you use daily, actually relies on.</description><pubDate>Tue, 25 Aug 2026 09:00:00 GMT</pubDate></item><item><title>Design Patterns: The Patterns Every Developer Actually Uses</title><link>https://www.akshatapp.com/blog/design-patterns-every-developer-uses/</link><guid isPermaLink="true">https://www.akshatapp.com/blog/design-patterns-every-developer-uses/</guid><description>Across seventeen posts, several recurring solution shapes have appeared without ever being named — a database&apos;s single connection pool, an event system notifying multiple listeners, a sort function swappable at runtime.
