> B. You could have multiple panels operate as a swarm.
Is that level of precision even remotely achievable with today's technology?
My understanding is that orbital insertion accuracy is in the ±10-50 meters range, with the most advanced formation flying satellite swarms hitting 10 cm to 1 m precision between satellites with the help of optical navigation.
But the precision between the panels on a telescope like JWST is in the sub-mm range, no?
Also, I'd assume stuff like orbital decay, atmospheric drag, gravitational perturbations, and solar radiation pressure would make it difficult to maintain precision over time.
I'm sure/hopeful there's some people here at HN working on stuff like this, please fill in and correct me!
Useful, but "your phone" will probably not the be the one telling you that. You'll have to use your supermarket app, and better be sure it will do all it can to track and extract every last bit of information about you and the contents of your fridge.
You're only buying eggs every second week? We can't have that, let's present you with a recipe that uses eggs. You still have those cookies you bought four days ago? Let's give you a coupon for milk.
And there will be a nice recipe or a coupon or a Very Limited Exclusive Offer you'll need to send to a friend, so now the app need access to your contacts, and why not sync that info with Meta, and oh look at that, we have a map of all our customers and their spending habits and geographical location and political orientation.
I'd take the widget! For me typing "calc" finds the "com.apple.calculator" folder. If I continue to "calcu" etc, it suggests "com.apple.ncplugin.calculator" instead. Brilliant intelligence right there.
As far as I know, watermarks never took off because the technical complexity and lack of standardization. Nielsen researched and developed ACR technology but it never required watermarks.
When Nielsen first started collecting data (1950s), they handed out diaries to a group of around 5 000 selected households. Nielsen would then collect these diaries and extrapolate viewing patterns across the entire population.
After that came phone surveys. Next step (1980s) was the "people meter", a small box attached to the TV that could automatically detect which channel was tuned and which household members were in the room.
In the 1990s the set-top box made all of that redundant as the cable and satellite providers could directly see which channel every single box was tuned to at all times.
Broadcasters: the cutting edge of streaming information is ours! Now let's make it so everyone unknowingly broadcasts as much info back to us as possible!

Both audio (sports) and video (netflix et al) watermarks are alive and well. They are used to trace piracy (ie account ID), not for content ID (at least AFAIK).
Yes, but 1:√2 keeps the ratio even when you rotate the screen vertically. A folded 1:1 screen becomes 2:1 when "unfolded" and the area doubles, so you can go from showing one 1:1 window to two 1:1 windows side by side. But when rotated to a vertical orientation, you can't just scale that 1:1 window to double its size. With 1:√2 you can.
ESPECIALLY the evolution of macos and ios.
