Origin trials are a way for developers to get early access to experimental web platform features. They’re carefully controlled “beta tests” run by browsers to ensure that the feature works and is worth more time on implementation and standardization. Check out Getting started with origin trials to learn more. What’s interesting to me is seeing […] The post Origin trials and tribulations appeared first on rviscomi.dev.| rviscomi.dev
Using regular expressions to parse HTML in BigQuery is a nightmare. Instead, we can use Cheerio in SQL to extract insights about the web.| rviscomi.dev
Until recently, I just assumed you could put anything equivalent to an HTTP header in an http-equiv meta tag, and browsers would treat it like the header itself. Maybe you thought the same thing—why wouldn’t you, with a name like that. But as it turns out, there are actually very few standard values that you […]| rviscomi.dev
