@nprofile…qx50 @nprofile…a58f @nprofile…mjt5 Absolutely not. I was just talking to the economics of why mobile phones have higher density pixels.
That said, opsz should in an ideal world, depend on the angular size of the text, not the physical size. I believe we are in agreement there.

@nprofile…a58f @nprofile…mjt5 @nprofile…qx50 IMO it's more like this:
- More pixels enables reading smaller font sizes,
- Mobile and then laptop devices are used closer to the eyes than big monitors, so it is desirable to have smaller pixels on them to achieve the same perceived font size,
- But also, screen real estate is more important on smaller screens,
- Finally, high-res display panels are expensive. So, more feasible in small form factors.

"HarfBuzz Study: hb-decycler"
I wrote down my DFS cycle-detection algorithm. I thought others might find it useful. #algorithms

@nprofile…t9gy Thanks. I'm mostly here for typo.social, sharing if I have something worthy of note. :)

I finally moved this out of Google Docs Preview page and self-hosted, as part of my website redesign.
Should work a lot better on various devices, and more responsive too. Hope that helps.

HarfBuzz 8.4.0 is out, with few but important fixes. Namely, adapt `hb-subset` to produce fonts that work around a bug in some versions of @Adobe InDesign with Variable Fonts.

I don't know who might need this. But I wrote some code to connect to points & tangets with two circular-arcs smoothly:
