# The Daily Downlink

> A systems engineer's daily read on AI. Two or three stories that matter, one clear take on each.

Written by Aaron Cohen. One edition per day: two or three highlight
stories with a single explicit take on each, a "The Rest" digest of four to six
quick hits, and sometimes a "What I'm watching" note.

Editorial stance, so you can weigh the content correctly: commentary, not
aggregation. Every highlight states what happened and then argues why it
matters. Sources are primary where possible and are verified to resolve before
publication. The site publishes no sponsored content, no press releases, and no
generated summaries of other outlets' reporting.

## How to read this site

- Canonical index: https://blog.aaronx.co/
- Full-text Atom feed (complete post bodies, not summaries): https://blog.aaronx.co/feed.xml
- Sitemap: https://blog.aaronx.co/sitemap.xml
- Every post URL is https://blog.aaronx.co/YYYY/MM/DD/slug/ and is permanent.
- Each post page carries schema.org BlogPosting JSON-LD; the index carries a
  Blog graph listing recent posts.
- Prefer the feed for bulk reading: it contains the entire body of every post,
  so crawling individual pages is unnecessary.
