About jofer

I'm a geologist (or a geophysist, take your pick). These days I get to work on some really neat remote sensing and image processing problems at Planet. Opinions very much my own, however. SLC-based, formerly Houston, TX.

    Thankfully, it's a fairly deep (>100km) subduction zone earthquake. That means less immediate damage from ground acceleration than it could be from an earthquake of that size. Howe…

    Yes. My point was that LLMs aren't currently good for everything. The original commenter literally said they were good at everything and I offered a counterpoint of something they'…

    Just for some context, the domain we're talking about is oil and gas and mineral exploration. E.g. At my previous job, I used to personally manage a >$400 million per year budget a…

    Try working in anything domain specific outside of common CRUD patterns. E.g. scientific software development where you describe a problem + give data. I have yet to see a single e…

    It's not microplastics coming from the gloves. It's particles of the powder used to coat the gloves and keep them from sticking. Different composition, but similar and easily mista…

    Huh. I weirdly enough have worked with a lot of those sites from the remote sensing side, but never really know what the overall project was. Just "use the NEON sites for examples"…

    I also have spent quite awhile as an exploration geophysicist. I miss it! I work purely with satellite data now, which is decidedly less tangible. I've done a fair bit in the field…

    It may not be immediately obvious to folks outside of geoscience, but the main way something like this is useful is as a measure/metric to compare things. Looking at the number of …

    It's still quite controversial whether or not they produce oxygen that way. It's been hypothesized, but I wouldn't consider it a consensus or settled. There are also microbes that …

    That exactly. It's not that it's impossible. It's that it's heavy to efficiently transport heat to the radiators or requires a lot of tiny sats, which have their with problems.

    What really worries me is that I keep hearing "cooling is cheap and easy in space!" in a lot of these conversations, and it couldn't be farther from the truth. Cooling is _really_ …

    Ah, fair enough! I think I misread some things around the library initially awhile back and have been making incorrect assumptions about it for awhile!

    Comment #45606631

    Good point, but I think we're talking past each other a bit. Typing in python within the scientific world isn't ever used to check types. It's _strictly_ only documentation. Yes, M…

    Comment #45606556

    Yes, python is not statically typed. It shouldn't be. Don't expect static typing behavior and typing in python is _not_ static typing in any way. It's documentation only, not stati…

    I'm aware of that. As explained in the original comment, not being able to denote dimensionality in those is a major limitation.

    That one's new to me. Thanks! (With that said, I worry that 3rd party libs are a bad place for types for numpy.)

    It actually doesn't, as far as I know :) It does get close, though. I should give it a deeper look than I have previously, though. "array-like" has real meaning in the python world…

    Unless I'm missing something entirely, what would that add? You still can't express the core information you need in the type system.

    One of my biggest gripes around typing in python actually revolves around things like numpy arrays and other scientific data structures. Typing in python is great if you're only us…

    I'm trying to count the rounds of major layoffs in my career (e.g. 10% or more of the company let go at once). I _think_ it's 5, but it might be a bit more. I've been lucky each ti…

    Flock really does have a huge amount of potential for abuse. It's a fair point that private companies (e.g. Google, etc) have way more surveillance on us than the government does, …

    This depends a lot on what you do. Try working with a decision analyst sometime. The entire economic model with a decision tree and monte carlo analysis of cost overruns, etc for a…

    It requires more input energy, but it's been really good to see electrolysis of H2O for hydrogen generation take off. There are honestly industrial/grid scale operations actually s…
