Could/would/should an element with `scroll-snap-align: center;` but a number of `display: contents;` between it and the scrolling element participate in scroll snapping and ScrollSnap events?

The Surprising Genius of Sewing Machines [video]

yewtu.be/watch?v=RQYuyHNLPTQ

Sewing machines are mechanical marvels – here’s how they work.

I've long felt that the sewing machine, & also the knitting machine, are closer to amazeballs voodoo black magic than "just" machinery. I giggled to see in the comments that at least a couple of other mechanical engineers concur!

So you Reblog things instead of liking them to make sure other people see it on here ?#howdoesitwork

Trying to make sense of this #SignedHTTP thing that #ActivityPub uses.

Looks like you sign some HTTP headers (minimally Date, but that by itself is pretty weak), which, if you care about the content means you also sign the Digest header, which is a hash of the content payload.

The keyid in the Signature header appears to be a URL referencing the ActivityPub Actor, so the accepting server then apparently grabs that (json) to find the public key inside and verify.

using my toot.cafe a/c to view the profile of others (incl those following me) on other instances (incl mastodon.social), I can't see the user's past toots, I can see only a limited number of follows/followers etc.

what behaviour is this? will the data populate over time?

I read about a new smart wall (glass) from NanaWall.

I was wondering how it worked. So far I only learned something about nematic liquid crystal displays (LCD). With the following cell configurations Fréedericksz cell, VA cell, twisted nematic LC cell (similar to the Fréedericksz cell).

I read a little in a book [1] about polymer dispersed LCDs (PDLCDs).
These displays can address states between a scatter mode, where the display looks like a opal glass panel, and a transparent mode. With a contrast ratio of approx. 40:1, compared to a newspaper with a contrast approx. 8:1.

That sounds very similar.

Some more information about PDLCDs:
The nematic liquid crystals are arranged as droplets in a polymer binder between two glass plates with electrodes.
These droplets have a random orientation and so the refractive index is random. This causes the light to be scattered at a wide angle to the observer (scattering mode).
By apply an electric field the molecules orient themselves parallel to the field. With the result that the refractive index is almost the same. This means that the light can not scatter through the display (transparent mode).

This type of display don’t require a polariser.
I think that’s a big advantage of this technology. This way don’t lose 50-60% of the light beam at the polariser. This enables us to achieve a high transmission rate.
In my opinion, one disadvantage is that we need an applied electrical field for the transparent mode. Because in this case I don’t want an opaque window at a power blackout.

This was just one possible technology. Wikipedia [2] lists these technologies: electrochromic, photochromic, thermochromic, suspended-particle and micro-blind and polymer-dispersed liquid-crystal devices.

Maybe you have another idea.

Now it's time. Good night.
