Although you are downvoted, there is a point; I wonder how many products are created just to be used as waste management when creating other products from oil
kuhewa · 4 months ago
I suppose many products were initially invented to get value or of an underutilized by-product, but as soon as there's a market and people want to buy it, the byproduct is no longer waste.

DPaint III finally granted me the ability to create animation, which was always one of my early dreams to be able to do. I combined my obsession of Lemmings with Judge Dread to create a series of shorts following the exploits of Judge Lem. Sad that I no longer have the disks for them, but I'm so thankful for how amazing and accessible DPIII was.

If you live in the U.S., marginal electricity demand during the day is almost invariably met with solar or wind (solar typically runs at a huge surplus on sunny days). Go forth and AI in peace, marcyb5st.

This made me wonder - do any cloud compute systems have an option to time jobs or use physical resources geographically based on surplus power availability to minimise emissions?

I reckon it might incidentally happen if optimising for cost of power depending how correlated that is to carbon intensivity of power generation, which admittedly I haven't thought through.

I recently encountered this in a sailing class when the teacher was explaining how "pull-mode" works in sailing, where the wind is coming from ahead of the vessel and pulls the sails rather than pushing them. I knew this theory to be debunked and yet couldn't work out the answer from non-debunked physics (and certainly didn't want to disrupt the class by arguing physics with someone who's been sailing for 50+ years - if it worked for him, it'll probably work for me, even if debunked).

Modern sailing vessels always sail into the wind, because they're always going faster than the wind blows. I do find the physics of this fascinating.

> Modern sailing vessels always sail into the wind, because they're always going faster than the wind blows.

Maybe state of the art hydrofoiling boats, cats and some quite large monohulls, but maybe that's what you meant by modern. Most sailboats built today have a pretty low top speed (due to hull speed limitations) relative to wind speed - monohulls often max out around 5-6 kts aren't going to be faster than the wind pretty much ever

I know this comment is totally innocent but it does kind of bum me out to be at a point in time where instead of addressing our impact on the environment directly, we're trying to make computers that can talk to dolphins so we can tell them to stay out of the way lol

You don't tend to hear about it and not that there isn't still progress to be made, but there has been tonnes of progress on fisheries interactions with protected bycatch species. For ex the infamous dolphin problem in the eastern tropical Pacific purse seine tuna fishery is down 99.8% from its peak to the point populations are recovering, despite the fishery intentionally setting on dolphin schools to catch > 150,000 t of yellowfin tuna per year.

Pelagic gillnets are probably the gear that still have the most issues with dolphin bycatch, and acoustic pingers that play a loud ultrasonic tone when they detect an echolocation click are already used to reduce interactions in some fisheries.

Steaks being cooked naturally drain juice. The entire concept of searing a steak "sealing" the juices in implies a cooking paradigm that simply doesn't hold up to experimentation. You want to cook off water mass from a good steak—it's better flavor, better texture, and you're left with far less grease in your soup-catcher.

If you cook enough steaks, it's quite hard to get a dry one, and you can get excellent texture and taste despite draining the "juice" (which is like 80% of why you salt the steak to begin with—moisture = less even and harder to control cooking which results in a chewier crust).

We had one on a yacht I crewed that did ecotour sorta sails. When we'd catch a small tuna, after the trips I'd butterfly it and George Foreman it. No added oil just right on the Teflon cooking surface and texture and taste would come out sorta like fried chicken. It was great
kuhewa commented on What a crab sees before it gets eaten by a cuttlefish   nytimes.com/2025/03/03/sc... · Posted by u/gk1

Crabs predate cuttlefish in the fossil record by a significant amount of time (~50 million years), but both have had a good 100 million years to battle it out and crabs are still blinded by the camo. Cuttlefish maybe have not exerted enough evolutionary pressure on crabs to make them adapt, or there are crabs that have adapted and we just don't know which species or have not discovered them yet.
kuhewa · 6 months ago
I'm not sure it's that unique of a situation though, most prey organisms have some antipredator adaptations but rarely are they foolproof, just like rarely are predatory adaptations like mimicry/camouflage/crypsis absolutely foolproof.

When I was much younger, we would go surfing in a wetsuit. When the water was cold, taking a piss would be a nice little break from freezing while the layer of water inside the suit warmed up. Sounds gross but it gets replaced over time while you're in the water.
kuhewa · 6 months ago
Oh yeah, 'charging up' your wetsuit is great. The replacement is fairly limited with a good suit especially if you have booties and a hood, but who cares, people pay a lot of money for skin care products with urea in them.

If I understand what's been published about this, it isn't just ideation, but also critiquing and ranking them, to select the few most worth pursuing.

Choosing a hypothesis to test is actually a hard problem, and one that a lot of humans do poorly, with significant impact on their subsequent career. From what I have seen as an outsider to academia, many of the people who choose good hypotheses for their dissertation describe it as having been lucky.

I bet all of these researchers involved had a long list of candidates they'd like to test and have a very good idea what the lowest hanging fruit are, sometimes for more interesting reasons than 'it was used successfully as an inhibitor for X and hasn't been tried yet in this context' — not that that isn't a perfectly good reason. I don't think ideas are the limiting factor. The reason attention was paid to this particular candidate is because google put money down.

That a UPR inhibitor would inhibit viability of AML cell lines is not exactly a novel scientific hypothesis. They took a previously published inhibitor known to be active in other cell lines and tried it in a new one. It's a cool, undergrad-level experiment. I would be impressed if a sophomore in high school proposed it, but not a sophomore in college.
kuhewa · 6 months ago
I'm sure the scientists involved had a wish list of dozens of drug candidates to repurpose to test based on various hypotheses. Ideas are cheap, time is not.

In this case they actually tested a drug probably because Google is paying for them to test whatever the AI came up with.
