# Coderwall

> Coderwall is a developer community where programmers publish and discuss short, practical programming tips ("protips") — code snippets, one-liners, configuration fixes, and how-to notes — organized by technology tag. The site describes itself as "a collaborative learning platform for software developers" offering "programming tips, tools, and projects from our developer community."

Generated 2026-10-29 from the live database, alongside https://www.coderwall.com/sitemap.xml. Counts below are current, not historical.

Corpus: 29,319 publicly visible tips carrying 14,254 distinct technology tags, written by 288,387 contributors, with 18,082 comments.

A deeper machine-readable listing is available at https://www.coderwall.com/llms-full.txt.

## Content model and URL patterns

- A tip lives at `/p/{id}/{slug}` and carries an author, technology tags, likes, and threaded comments (labelled "responses"). Tip pages emit schema.org `Article` structured data with author, headline, keywords, and comment count. Requesting `/p/{id}` with a stale or missing slug redirects permanently to the canonical URL.
- Site-wide feeds re-sort the same tip corpus: `/trending` (by a time-decayed engagement score, requiring more than two likes), `/popular` (by view count), `/fresh` (newest first). Paginated as `/trending/{page}`, `/popular/{page}`, `/fresh/{page}` at 40 tips per page.
- Topic hubs re-sort tips for one tag: `/t/{topic}/popular` and `/t/{topic}/fresh`, paginated as `/t/{topic}/popular/{page}`. A handful of topics are curated categories that expand to several tags (for example `/t/tools/popular` covers git, devops, command-line, and OS tips).
- Contributor pages: `/{username}` (profile), `/{username}/protips` (their tips), `/{username}/comments` (their comments).
- The job board lives at `/jobs`, with individual postings at `/jobs/{id}`.
- Product comparisons live at `/categories/{slug}` (category) and `/products/{slug}` (individual vendor).

Primary entities: Coderwall (the organization and brand, publisher of every tip, on X/Twitter as [@coderwall](https://twitter.com/coderwall)); protips (the core content unit); topic tags (the taxonomy); community members (authors and commenters); the Coderwall job board (the one paid product, $299 for a 30-day programming job posting).

Authoritative sources by topic: `/popular` and `/trending` for the highest-traffic tips overall; `/t/{topic}/popular` for a given technology; the individual tip page for a specific technique; `/{username}` for a contributor's body of work; `/jobs` for hiring.
