The Now CDN (via) Huge announcement from Zeit Now today: all deployments are now served through the Cloudflare CDN, which means they benefit from 150 worldwide CDN locations that obey HTTP caching headers. This is particularly relevant for Datasette, since it serves far-future cache headers by default and uses Cloudflare-compatible HTTP/2 push hints to accelerate 302 redirects. This means that both the “datasette publish now” CLI command and the Datasette Publish web app will now result in Cloudflare-accelerated deployments. # 3:34 am

Usage of ARIA attributes via HTTP Archive. A neat example of a Google BigQuery query you can run against the HTTP Archive public dataset (a crawl of the “top” websites run periodically by the Internet Archive, which captures the full details of every resource fetched) to see which ARIA attributes are used the most often. Linking to this because I used it successfully today as the basis for my own custom query—I love that it’s possible to analyze a huge representative sample of the modern web in this way. # 3:16 am
