> What about taking 3 photos while quickly changing the filter

Works great. Most astro shots are taken using a monochrome sensor and filter wheel.

> filters are something like quantum dots that can be turned on/off

If anyone has this tech, plz let me know! Maybe an etalon?

> If anyone has this tech, plz let me know!

I have no idea, it was my first thought when I thought of modern color filters.


That's how the earliest color photography worked. "Making color separations by reloading the camera and changing the filter between exposures was inconvenient", notes Wikipedia.

I think they are both more asking about 'per pixel color filters'; that is, something like a sensor filter/glass but the color separators could change (at least 'per-line') fast enough to get a proper readout of the color in formation.

AKA imagine a camera with R/G/B filters being quickly rotated out for 3 exposures, then imagine it again but the technology is integrated right into the sensor (and, ideally, the sensor and switching mechanism is fast enough to read out with rolling shutter competitive with modern ILCs)


I would not enjoy that future, but I think it's important to ask why. Is the future of humanity at stake or just our job prospects?

Edit: Whoops, looks like this is only for the contiguous US, which is somewhat higher than the global average.

Your link isn’t working for me but the IPCC middle of the road scenario has 10in by 2100 and past IPCC middle of the road estimates from the 90s have so far turned out to be reasonably accurate predictions.

I'd trust the IPCC over me any day of the week.

After digging into it a bit to find a better source for you, it turns out that my number was wrong anyway. Turns out the sea level rise for the contiguous US is expected to be quite a bit higher than the global average. I had no idea!

That said, I don't think they assume our emissions trend from the last 50 years will continue unabated.


I'm not particularly familiar with modern webdev, can anyone share a minimal example?

I had assumed this was a 25 year old article at first glance. Those dithered gifs sure are a throwback!

100% agree. Box of blocks cannot be beat. My sister and I used the hell out of ours: we built towers, cantilevers, mazes, Rube Goldberg devices, houses for rodents, vehicles, elaborate locks, catapults, you name it. They're still in the same condition as day 1, ready for our children.

Big flat conductive panels make good reflectors.

That makes sense but my first thoughts were that panels wouldn't be oriented so that the majority of that flat surface was perpendicular to the radar but instead much closer to parallel, and that aviation radar would be higher up than a house roof to avoid ground clutter.

Wonder if it can be leveraged as for passive radar. Synthetic aperture also comes to mind.

I’m clueless in this field tho.


> If the algorithm "working as intended" consistently downranks stories that cast a bad light on YCombinator, the sorts of people y'all mingle with, or the tech industry in general...is that any better than putting your thumb on the scale?

That's the exact opposite of what Dan stated, what this thread (and your link) demonstrate, and my own lived experience here.


that's fair but the post was on page 3 for a while. glad to see it restored to the front page. (the charitable explanation is that non-moderators can flag stories, as opposed to an official policy to protect YC companies)

Maybe the algorithm down-ranks posts that have lots of down-voted comments? Lots of light-grey text on this page.

This thread required manual intervention to override the algorithm - intervention that it did not always have and not all stories benefit from.

My argument is that the algorithm, as well as the various gameified engagement mechanisms on this site, are badly conceived and gives too much censure and veto power to ordinary users.


"Sometimes shit happens" should be viable in a courtroom sometimes, but by nature competition rules leave less room for interpretation.

I think it's exactly their popularity that lead people to call the big awards shows "a joke." Pretty common with stuff like the Emmys and Grammys.
