A useful reference shows its working.

Choose the page that fits your question

Latest shows recent discoveries and material guide updates. Explore includes emerging subjects that still need verification. Guides explain a task with inputs, steps, examples and checks. Stacks help you choose tools for a particular job, with links to their implementation guides.

Reading is free. You can download guides and starter files where provided. Following a stack saves it in this browser; clearing browser storage removes those guest saves. Accounts, paid membership and a native mobile app are not required to read the reference.

How research reaches the site

A research session is scheduled every six hours. It samples public GitHub, YouTube, X, Reddit, Hacker News, Hugging Face, creator projects, research and official documentation. The researcher follows unfamiliar subjects to primary sources and compares the results with independent sources to look for omissions. It also reviews overdue guides and guides affected by a finding.

These are bounded research sessions, not complete platform feeds. Access failures, indexed-only results and incomplete time windows are recorded. The research computer and app must be available for a run; the website continues serving previously published content if a run cannot finish. A schedule is not evidence that a check succeeded.

Research history shows the actual sessions, coverage and changes. Source status also lists the separate repository-release collector and its last recorded checks.

What each evidence label establishes

• Needs verification: a useful lead whose identity, availability or claims are not sufficiently established. It is not a recommendation.
• Primary source read: documentation, an original announcement or a paper supports the stated facts. It does not mean we installed the software or reproduced a benchmark.
• Local example check: the guide states which original helper code was run and what passed. That check does not establish that an external model or complete workflow was tested.

A practical guide must be usable

Look for prerequisites, a concrete input and output, ordered steps, copyable examples, expected results and recovery instructions. Product facts link to sources; original exercises are labelled separately. When access or behavior is uncertain, the guide names the gap instead of inventing a working setup.

Scheduled research can publish substantive guide revisions. Earlier versions remain available, and an unchanged source recheck does not create a new edition of the guide. A source-check date is not a product release date; the guide revision date records a material content change.

News, attention and recommendations

A launch establishes what a publisher announced. Popularity indicates attention, not independent proof of usefulness. A stack replacement needs task-specific evidence, compatibility checks and an assessment of migration effort. Automatic stack replacement is not enabled.

Release records preserve a version, date and source link. Where we have reviewed the release notes, an additional explanation names affected behavior and checks to make before upgrading. Those checks are guidance, not evidence that we tested your integration.
