> Debate is for the observers, not the participants, to learn about all sides of an argument at the same time. There are different types of debating, which may cloud the question; debating once or twice a year on a single prepared topic

You can use the green part of the spectrum for LiDAR. It’s what they use for bathymetric LiDAR.

"Because it measures in the infrared, it even works in the /dark/" No, because it's an active rather than passive light sensor, it works in the dark. Edit: also, the fact that you can see a green dot heavily implies

My assumption whenever I see that behaviour in a response is that the responder simply does not know the answer to the question asked. It’s fine, I think, to answer a question and then suggest a better method. It’s presumptuous in the extre

I looked it up, and LEO = <2000km altitude, and rEarth = ~6300m, so surface area of a sphere with r=6300km => ~500,000,000 km^2 surface area of a sphere with r=8300km => ~860,000,000 km^2 so roughly 1.5x the surface area at max LEO

Has anyone heard much about the Telesat Lightspeed program? As far as I can tell, there is no regular consumer access planned for it. It seems like a missed opportunity on their part.

These (and the ones in the GGP post) are very good points. To play devil's advocate, - With data plans based on minimum speed, there would still be a possibility of service being degraded below the paid-for minimum speed during times o

Sad to see. Pancreatic cancer is one of the scary ones, since there are so few symptoms before you hit stage 4. For those who haven't seen it, Freedom Downtime is a movie by the 2600 gang which is mostly about Mitnick's imprisonme

My corolla takes 10' long boards. Never maxed out the bags of mulch, but it's >10 for sure. Have been thinking about a roof rack for sheet goods. Can't see why it wouldn't work.

Again, not a geologist (or glaciologist), but glaciations happen frequently, in geological terms - every 40k? years or so. And, they don't dig very deep. Mines go >1km deep, so are below what I think any glaciation would have an eff

Wasn't one of the lessons of The Mythical Man Month that building from a spec produced good software? That was talking about System/360, my recollection is that most of the effort went into creating a very detailed and internally

Direct temperature measurements go back century or so, but proxies for temperature go back much further. Error bars may be larger but it's not like there's nothing to base the models on.

Not generally known, I think, but Canada is technically part of ESA. Not a full member, a 'Cooperating State', but there are some benefits. Wiki sez "Canadian firms can bid for and receive contracts to work on (ESA) programme

I'm absolutely sure they've thought of this, but I do wonder why they don't just divert the rivers around it and mine the entire place like an open-pit mine. Cart the square km or two of material off to some processing locati

There's a live coding talk by John Carmack where he uses Racket for making small programs for the Oculus: https://www.youtube.com/watch?v=ydyztGZnbNs He seemed happy enough with the language.

I don’t like the academic publishing racket either, but that is an exaggeration. Presumably you were being sarcastic, but it’s still caustic. What stereolab called easy cynicism.

I find those cutesy error messages just make a bad situation worse. Error descriptions are probably too much to ask these days - I would bet they'd be perceived as intimidating by the UX group, given that the same group seems to prefer

This line was good: "The sheepish alienation of sitting through “Inside Out” amid the static of my fellow-theatregoers’ sniffles and nose honks must have been what Data from “Star Trek” felt like all the time."
