I really appreciate the offer! As I mentioned in a separate comment in this thread, I think my next steps are probably going to involve moving experimenting with stitching together larger mosaics and camera calibration work. I also recently

Yes, it definitely is! Part of this comes from the fact that the images that I'm pulling from the drone are raw, meaning that there's a certain amount of distortion [1] that is induced. As a result, the pixels themselves are not o

Hi, author here (so cool to see this on HN!). That's a good call, and one I made sure to take into account. Instead of being a perfect 8 ft. x 6 ft. as advertised, the actual dimensions were a bit smaller at 92" x 67", which

On the other hand, I think one protection against this particular scenario are the people who make their money using their likeness. Like, what if in that particular situation, Taylor Swift's dad (pick any celebrity) was the one brows

I suggest you look into the American Prairie Reserve! It's a really interesting non-profit located in Montana, which is dedicated to creating one of the largest uninterrupted pristine North American grassland biomes in the country. The

Is this, like, actually true? I was under the impression semver is particularly useful during that stage because it (is supposed to) provides guarantees around which things break and when. I know, for example, many foundational Rust librari

If you're interested, a research group at UC Santa Barbara put together an open source web application [1] prototype specifically for doing visualization and mapping of Ping echosounder data from an autonomous surface vessel[2]. You co

Similar to Tailscale is the Innernet project, which has similar goals but is fully open source (also built on Wireguard). I've heard that set-up is a bit more painful, but for those who are interested in FOSS or self-hosting, it might

Shameless plug: I wrote a pair of articles for The Gradient that explores much of this area as well, called "Machine Learning, Ethics, and Open Source Licensing"[1][2]. I'd like to think those have a bit more depth and nuance

While I agree that criticizing by-definition world-class athletes' athleticism isn't particularly becoming, I am little curious regarding the "anyone of us on HN" specifier. Is the implication that HNers are, in particul

I think that your observation of water is probably spot-on. When it comes which RF frequencies get absorbed, with water the answer is pretty much "yes". Combined with what I'd imagine is some really fun scattering math tossed

+1 for sled--I was working with it this morning for a personal project, and it's frankly just really well built. Beside the great documentation and easy use, I kept finding myself looking for architectural tips for structuring Config s

I just updated this evening from Pop!_OS 20.10. It was pretty painless while using their built-in pop-upgrade tool, even on non-System76 hardware. First impressions are it largely still feels like the previous Pop! (which I'm personall

This is a bit tricky, because at least in the U.S., I don't believe it's settled question in law yet. Some of the other posters on here have said that the resulting model isn't covered by GPL--that's partially true, but

By far the most exciting thing about this announcement is this feature: "Detailed information on what a recruiter did with your application." I've been wishing for something like this for years . Especially for early-career

I'm not sure if the parent was referring to Blue Origin as a space program, but Amazon very arguably is developing a space program of one sort or another, with services like AWS Ground Station [1] for operating satellites coming online

I'm sorry, I think we definitely have a "pot meet kettle" situation here. You're (pretty patronizingly) describing noting selection bias, then basing things on your own situation. The median income for mechanical enginee

For one, I'd argue that working from home probably requires additional pay over working in the office. I'm sure some people have a "spare" bedroom that they can convert into an office, but there's a lot of people, i

Completely aside from the point you're trying to make: it's a pet peeve of mine when people try to describe collisions in terms of kinetic energy. It's the wrong metric--the important conserved quantity in collisions is mome

Ah, gotcha. It still might be worth adding your name to the waitlist--sometimes spots open up because students have to drop out. I'd honestly guess the biggest issue right now is COVID. Many (most?) universities are still being very s

If I'm remembering correctly, the requirements are something like 100-150 hours of coursework, plus around a dozen training dives; that gets you your basic certification. Past that point, as you get more practical experience, you'

It really depends! I'm currently on staff at a university, and some of my time moving forward will be allocated towards helping a research project that needs a diver with some instrumentation skills. I do know at least two people who h

Not sure if you're in the US, but once you get your Open Water certification, you might want to see if there's a university near you that offers the AAUS[1] scientific diving course. It can be a path for being able to do underwate

I think that there's some degree of "you can't get to the moon by climbing taller trees" happening here. There are methods that can be promising for gardens, and even smaller-scale farms (less than triple-digit acres, sa

Is there a way I'm missing to save comments on HN besides also commenting on them so they can be revisited later? I'd like to save this. This is one of the best meta-summaries I've ever seen, on any topic.

I liked hanging around parking lots being a goofball. Not that it wasn't a privilege to be in that position and that teenagers shouldn't be able to support themselves through work if they need or want to, but I'm also glad
