DeepWiki: Understand Any Codebase

news.ycombinator.com Sahar Mor 2025-11-01 16:23:30

Welcome to another post in the AI Coding Series, where I'll share the strategies and insights I've developed for effective AI-assisted coding. In this post, I break down how I use DeepWiki - my go-to tool for understanding unfamiliar codebases, spinning up dev environments, and generating context for coding agents like Claude and Cursor. Whether you're evaluating an open-source repo, onboarding to a new project, or building an AI-powered dev tool, DeepWiki can save you hours. Note: This is not

Iterative DFS with stack-based graph traversal (2024)

news.ycombinator.com Daniel Farlow 2025-11-01 14:09:08

Depth-first search (DFS) on a graph (binary tree or otherwise) is most often implemented recursively, but there are occasions where it may be desirable to consider an iterative approach instead. Such as when we may be worried about overflowing the call stack. In such cases it makes sense to rely on implementing DFS with our own stack instead of relying on our program's implicit call stack. But doing so can lead to some problems if we are not careful. Specifically, as noted in another blog post,

Top Secret: Automatically filter sensitive information

We’ve written about how to prevent logging sensitive information when making network requests, but that approach only works if you’re dealing with parameters. What happens when you’re dealing with free text? Filtering the entire string may not be an option if an external API needs to process the value. Think chatbots or LLMs. You could use a regex to filter sensitive information (such as credit card numbers or emails), but that won’t capture everything, since not all sensitive information can

“Every frame has something unnerving in it,” Patton Oswalt says in the trailer for Chain Reactions—a new documentary about the enduring influence and impact of 1974’s The Texas Chain Saw Massacre. Tobe Hooper’s grisly classic has often been imitated and has spawned some regrettable sequels and remakes, but the original remains a uniquely terrifying product of a very specific time and place, not just in pop culture, but also in the realms of independent cinema.

STARBASE, Texas—I first visited SpaceX's launch site in South Texas a decade ago.

A few years later, in mid-2019, the company had moved some of that dirt and built a small launch pad.

Unsealed Apple Pay ruling explains Fintiv’s Texas retreat and weakens new Georgia case
