The old developer archive

Between 2012 and 2015 this site published tutorials on PHP, Arduino, Solr and server tooling. Those articles have been retired — the code they described has moved on, and leaving them up would have meant handing out advice that no longer works.

The site now covers search and analytics: how pages get found, how traffic gets measured, and what changes as answer engines take over part of search.

If you arrived from an old link, these are the closest current starting points:

• Core Web Vitals — the successor to the old performance write-ups
• JavaScript SEO: rendering and indexing pitfalls
• GEO vs SEO: what generative engines change
• Server log file analysis — the closest thing to the old sysadmin material
