I imagine you are correct that there were a few steps/techniques not shown in the video.
Say you have a bunch of dynamic business rules that you need to apply onto a calendar of days, or a canvas of spreadsheet cells, or another discrete collection of slots where information could go, or even a continuous domain (in all of which some type of gap-filling and continuity might be desired).
Rather than looping in one pass over your rules, and trying to figure out how to simultaneously fill gaps and write meaningful information into specific places, it might be helpful to first pass over your rules and think "where is the support area that might be needed, all of the places where some rule or combo of rules might write information." After all, if you're just thinking about support, you can trivially combine things, because you're just applying some kind of union operation as you go along.
Then you can do another pass, where you worry about order and precedence and complex inter-rule interactions, while knowing you already have a pre-made "canvas" on which you can paint and - in the real-world analogy - play with color and texture and all that fun stuff.
Of course, you no longer have an algorithm that can handle streaming data, but two passes are still O(N), and the resulting code can be infinitely more readable.
(To the mathematicians out there, I do apologize for being inspired by, but completely ignoring the nuance of, https://en.wikipedia.org/wiki/Support_(measure_theory) - but I think it's a useful mental model even when generalized in a less-than-mathematical way!)
// Daddy, chill. Two passes are still O(N).
// Got a performance issue, hide it in the constant, don't expose it in the f(N) :-)
Same logic as to why you can assemble a set of identical pieces of IKEA furniture faster if you first do step 1 for all pieces, then step 2 for all pieces etc, than if you assemble the pieces one by one.
Mathematician here. We steal real-world terms and use them in technical ways all the time. It's OK to use real-world terms like "support" non-mathematically.
“How do I look?” “Like a cheap French harlot” “French!?”
Now if only we had been more glamorous about it we could have beaten this company by 30 years!
And where exactly does that fall in terms of indecent exposure? Make sure the bits that the law requires covered have solid patterns at that point, it seems it would be legal.
(On the other hand, I have doubts about the practicality of wearing body paint in ordinary life--what can be durable enough to take what life routinely dishes out, but easy to remove? He also missed the fact that people only in bodypaint should follow nudist convention and sit on a towel.)
I avoid synthetic fabrics to begin with because in a fire they turn to melted plastic and cause instant 3rd degree burns. Natural fabrics will char, protecting you a little bit in the process, and simply not make your injuries any worse. This spray fabric is sure to be far worse, an absolute nightmare in the event of fire.
Those are flammable too, I guess...
I would simply stay away from open flames when wearing this dress.
I've worn a fleece that got burned while I was wearing it, one time while tending to an open fire, another time with a soldering iron, in both cases it clearly did not want to propagate, I just ended up with a small patch of shrivelled up fleece/hole that didn't stick to my skin, in fact I'm pretty sure the fleece saved me from a burn in the case of the soldering iron... I'm sure that if you were fully engulfed in flames for long enough it would start to stick to your skin (which is not exactly an exclusive property of that fabric), but that's not what you were suggesting.
I mean, I do the same, but that's cause I play with fire on a regular basis, and haven't met anyone outside those circles who care about such features as char vs melt.
> The biggest problem, however, was that the drying process took 2–3 minutes before the condom was dry enough to use, which was too long to be truly marketable.

this sounds very useful so you don't need to have bandages of different shapes/sizes in your first aid kit
It sterilizes and seals, pretty much replacing my whole bandaid kit I used to keep in my pocket book.
I'll even buy a bunch at a time and give them out to friends. It's so useful yet no one knows about it.
(That said, you won't be sealing bullet wounds or giant gashes with it)
Wtf? What grim meathook future establishment would involve wearing spray-on smart clothes that monitor my vitals? Need to know so I don't accidentally go in there.
Step into the booth, press the button. First, the spray-on tan, then a quick dry, then spray on clothes.
Step into the booth again at the end of the day to wash it all off and recycle it for tomorrow.
Because they definitely inhaled some of that.
Ever stand at a crosswalk on a busy street? You are inhaling brake dust from the pads. You know what brake pad dust is made out of? Asbestos.
Go on, tell me particles in your lungs are trivial. Let me know if you still think that after you are 50+

Surely they could have used drones with leering red LEDs to apply the material.
Alexander McQueen was one of a kind.
I wonder how strong the resulting layer is. The should straps being adjusted in the video show that it's definitely not weak.
Okay
The spray-on fabric is applied using the likes of aerosol tech, industrial sprayers, and 3D printingI do think it's cool, though. My body is too crap to pull somehting like this off, sadly.
It makes sense for Wired to write about this just for clicks, (as evidence being linked here). No need to be a submarine - those are for un-viral subjects.
The high score your snarky comment has is amusing as I remember a top post fro earlier in the year with vocabulary words that HN readers were below-average in comprehension (compared to e.g. the average woman), and many of them were fashion terms like "peplum."
Ah yes, those sweet non-toxic bonding agents
I have my doubts whether breathing the small fibrous particles that are contained in the spray won't have some unhealthy consequences.
Ok, then show me that. That is interesting. Show me a painted-on body suit after ten trips through the washer/dryer. Who cares about some spray-painted model?
consists of short fibers bound together with polymers and bio polymers, and greener solvents that evaporate
So he shredded fabric and mixed it with paint. Who thought this drivel was newsworthy?
Yes.
> ...like the one on Hadid's body
Absolutely not. If you watched the video, the end result was a garment that was not stuck to the wearer. The straps were independent from the shoulders. The rest of it flowed and fluttered like real fabric, and not like the typical "spray on dress" we've seen before. It's not a coating once finished. It's a separate thing.
Notice how the fabric didn't cling to her inner legs, but bridged that gap instead.
Now I agree that I'd like to see how durable this thing is once it's been washed. I'll accept whatever wash method is standard for a fancy dress. That is: if it can't be tossed into a normal washing machine, but can be handwashed with Woolite in the sink, then that's good enough for me.
