I imagine it's not, but can also see automated systems flagging the number as being the recipient of messages for over a hundred different financial institutions.

Was the number used to sign up for, and receive communications from credit card companies? Is the ban related to signing up for +100 cards?

I made a video showcasing some advanced techniques to use fonts on the web, without compromising performance. Covers interesting font metrics like ascenders and descenders. Fascinating to see how much information is contained within a font file!

Really like the simplicity of your website. I think when you first announced it, you mentioned you might open source Magic Loops, might you do that?

umaar — Wed, 19 Apr 2023 21:52:01 +0000

Hey HN, have seen a lot of AI demos recently using libraries/frameworks for what is effectively an API call - so thought to showcase how this could be done with vanilla JavaScript. Turns out response.body is an async iterable, so you can do something like:

  for await (const chunk of response.body) { // use chunk }

This blog post shows S3 Glacier Deep Archive costs $2.05 USD for 2 TB but on the AWS pricing page it's showing as 2,000 GB * $0.0018 per GB = $3.60 ?

Edit: this is for London pricing, guess it's a bit higher.
