why would I want to use it?

You wouldn’t, but that’s fine with Match Group: JP Morgan[^1] are loving this new monetization strategy. If they think they can get more money out of their users they will, the experience and usefulness of their app be damned. Very similar to aggressively monetized mobile games, but extra icky since they’re monetizing human relationships.

[^1]: I’m sure other investment firms are pleased as well, but JP Morgan was the firm mentioned in the article

Did the fix end up working in the end, or did restoring everything from backups mean that the fix didn’t work out either? (I don’t use Jerboa or any other lemmy apps, so mainly just curious.)

(I’m going to write with confidence, but I’m not an expert, just grew up around chefs. Please feel free and welcome to fact check me.)

Yeah, EVOO is made by cold-pressing the olives, and regular olive oil by hot pressing. Cold pressing releases less oil and also several tasty compounds that come along for the ride. Hot pressing releases more oil but also other compounds that don’t taste as nice, so generally regular olive oil will then be refined, removing most of the compounds that give it flavor. If you compare, you’ll find that real EVOO[^1] tastes distinctly olive-y, and regular olive oil has very little flavor at all.

When it comes to cooking, traditional advice is not to cook with EVOO because it’s got a low-ish smoke point[^2], whereas regular olive oil (which has been refined) will have a higher smoke point. EVOO’s smoke point isn’t actually that low, but I generally avoid high temp cooking with it anyway in favor of things like avocado oil (my personal go-to), peanut oil, or vegetable oil which are very tolerant of high temperatures. You absolutely can cook with EVOO though if you only want to keep one kind of oil around the house or something.

To clarify: heating up EVOO and cooking with it is fine as long as you don’t smoke it. It won’t make it any less extra-virgin or anything: to get those less good-tasting things into your oil, you need to heat up the olives themselves.

So are you wasting money if you do cook with it? Maybe.

Do you want what you’re cooking to taste like olive oil? If you do, cook with it! Real[^1] EVOO has a distinct taste that won’t go away when heated (unless you smoke it). It’s great for making stuff like olive oil cake! If you don’t care or don’t want that flavor in whatever you’re cooking, then yeah it’s probably a waste of money. There are many less expensive oils that will work well and have neutral flavors or different flavors that you might prefer, including regular olive oil.

[^1]: All of this is avoiding the issue of regular olive oil being passed off as EVOO when it actually isn’t. If you want something interesting to read about this evening, try researching olive oil fraud.

[^2]: In case you don’t know, smoke point is the temperature where an oil starts to burn, which tastes bad, isn’t very healthy, and will probably set off your smoke alarm.

Glad you found it useful! When I started writing it nobody else had answered and by the time I posted it a bunch of other people had replied (that’s what I get for walking away while writing it).

Always nice to see studies of these things! I feel like there’s a lot of olive oil lore out there, it’s cool to see that some of that lore checks out scientifically.

Yesterday was very productive and then I got to spend the evening gaming with friends, so that was nice!

The Cosmic Wheel Sisterhood! It’s a really good visual-novel-style game, but with the added element that you craft your own tarot-style divination deck and then draw cards from it during some conversations, and which cards you draw influence what kinds of readings you can give for people. It is established early on that since you were a kid your readings have never been wrong, and fittingly the game warns you early and repeatedly that your answers will affect your fate, dramatically. Well, no kidding! When I was playing yesterday I had a choice that I’d made hours earlier come back and bite me in the ass, hard. Almost made me want to quit and start over, but I’ve decided to see this play-through through and if by the end I still feel like I need to fix my mistakes I’ll maybe play it a second time.

tl;dr if you like beautiful pixel art, enigmatic beings from outside of space and time, witches, tarot, and/or choices that actually matter in your games, do give this one a go! I’m not done with it yet but I’d already love to chat with someone else who’s played it!

I’ve put a few hours in and I agree, it’s just a fun little game that slowly pushes you bit by bit into slightly more challenging stuff. I really like how well the game meshes the diving and sushi restaurant aspects, too. (Plus, I’m a scuba diver – still pretty new to it – and I’m a bit on the larger side, so it’s a nice bit of representation.)

In FFXIV, I’m in the post-Shadowbringers DLC content. I’ve taken a bit of a break from the MSQ to get the Nier-themed alliance raids

Are you me? I’m just a bit into the post-ShB patches, and I just finished unlocking all three Nier raids. They’re really fun (although I agree: challenging). If you happen to be on Crystal DC and want to party up for some raids or something, lmk!

Think I might try a healer class next, just not sure which one

As someone who is very much a non-healer main, I quite like Sage. My first healer to 90 was actually Scholar, but a lot of that had to do with the fact that I was really into Summoner for a while: when I’m going to heal I usually hop on Sage.

Sentient, spacefaring bees, according to the article! Not what I was expecting but still, sounds pretty intriguing!

realChem, 9 months ago

Agreed. Strong (and effectively enforced) worker protections are just as important as tech-specific safety regulations. Nobody should feel like they need to put themselves into a risky situation to make work happen faster, regardless of whether their employer explicitly asks them to take that risk or (more likely) uses other means like unrealistic quotas to pressure them indirectly.

There are certainly ways to make working around robots safer, e.g. soft robots, machine vision to avoid unexpected obstacles in the path of travel, inherently limiting the force a robot can exert, etc… And I’m all for moving in the direction of better inherent safety, but we also need to make sure that safer systems don’t become an excuse for employers to expose their workers to more risky situations (i.e. the paradox of safety).

Some pretty interesting ideas. I was unaware that anything was living in the Atacama salt deposits, which certainly lends some credence to the idea that something could be pulling moisture out of the air on Mars, thin as it is.

realChem, 9 months ago

Yeah, cryptobiotic crust! I’ve seen it in the Sonoran desert. It doesn’t look like much, I think if I hadn’t been warned ahead of time not to step on it I might have just done it without thinking. Given that just footprints can take on the order of decades to heal I think a dune buggy ban makes sense in areas where it grows.

I’m still surprised to learn about the microbes in the Atacama: it’s the driest place on earth, and I would have expected the salt deposits to make it even harder for anything to live there. Yknow what they say I guess: “Life, uh, finds a way.”

That’s a real mood, yeah.

I just recently decided to stick with mine. I was having a lot of doubts: feeling like I wasn’t making and progress, like I wouldn’t actually be able to finish the projects I started, impostor syndrome shit, etc. I’m happy I decided to stick with it. I just cleared some big milestones and I’m in the middle of a nice long vacation now, and I’m feeling excited again about my work.

On the other side of things, I’ve got a friend who decided to leave his PhD program with a masters a few years ago. He’s now heading up product development for a robotics startup, doing quite well for himself.

I don’t think there’re any wrong answers here. Do what will make you happiest. Maybe you just need a vacation, maybe you’re ready to move on. And remember that education is never wasted: even if you decide not to finish out the PhD, you’ve still learned a lot and that’s valuable with or without the piece of paper and title.

Best wishes, friend, whichever way you decide to go ♥

That’s great news, and fantastic timing! Good luck on the interview, though I’m sure you’ve got this.

realChem, 10 months ago

For sure. They tend to do a good job communicating tricky science and math concepts as well. They interview experts in a coherent way, tend to take the time to properly set up the background for topics, and the writers there seem to really care about getting things right rather than being sensational. They’re one of my favorite sites for stories about math and science honestly.

I haven’t had a chance to read the article linked in this post yet, but I’ll be sitting in an airport in a few hours (I really need to go to sleep now) and I’ll look forward to reading it then!

Yeah I’ve heard a lot of people talking about the copyright stuff with respect to image generation AIs, but as far as I can see there’s no fundamental reason that text generating AIs wouldn’t be subject to the same laws. We’ll see how the lawsuit goes though I suppose.

realChem, 10 months ago

Well I hear what you’re saying, although I don’t much appreciate being told what I should want the outcome to be.

My own wants notwithstanding, I know copyright law is notoriously thorny – fair use doubly so – and I’m no lawyer. I’d be a little bit surprised if NYT decides to raise this suit without consulting their own lawyers though, so it stands to reason that if they do indeed decide to sue then there are at least some copyright lawyers who think it’ll have a chance. As I said, we’ll see.

realChem, 10 months ago

It seems like you’re working under the core assumption that the trained model itself, rather than just the products thereof, cannot be infringing?

Generally if someone else wants to do something with your copyrighted work – for example your newspaper article – they need a license to do so. This isn’t only the case for direct distribution, it includes things like the creation of electronic copies (which must have been made during training), adaptations, and derivative works. NYT did not grant OpenAI a license to adapt their articles into a training dataset for their models. To use a copyrighted work without a license, you need to be using it under fair use. That’s why it’s relevant: is it fair use to make electronic copies of a copyrighted work and adapt them into a training dataset for a LLM?

You also seem to be assuming that a generative AI model training on a dataset is legally the same as a human learning from those same works. If that’s the case then the answer to my question in the last paragraph is definitely, “yes,” since a human reading the newspaper and learning from it is something that, as you say, “any intelligent rational human being” would agree is fine. However, as far as I know there’s not been any kind of ruling to support the idea that those things are legally equivalent at this point.

Now, if you’d like to start citing code or case law go ahead, I’m happy to be wrong. Who knows, this is the internet, maybe you’re actually a lawyer specializing in copyright law and you’ll point out some fundamental detail of one of these laws that makes my whole comment seem silly (and if so I’d honestly love to read it). I’m not trying to claim that NYT is definitely going to win or anything. My argument is just that this is not especially cut-and-dried, at least from the perspective of a non-expert.

realChem, 10 months ago

Totally agreed, but I was also surprised not to see raisins on your list! They’re great cooked right along with the oats: they’ll soak up a little water (or milk if you do it that way) and plump back up a bit, and they make for delicious bites. I also usually make steel-cut oats in a rice cooker – they don’t come out quite as delicious with quick oats because they don’t get as much opportunity to suck up water, but they’re still good.

Exciting stuff. I’ve long since vowed never to pre-order anything from Bethesda ever again though, so I’ll be waiting to hear what the vibe is once other folks start playing it. Right now it very much seems like it could either be great or disappointing. We’ll see in a couple weeks’ time I s’pose

realChem, 10 months ago

I’m personally not so much worried about it being buggy or broken, that stuff gets patched. I’m more worried that it’ll be fundamentally disappointing in some way, which is something that I probably wouldn’t discover until long past the refund window. To be clear, I’m cautiously optimistic, but that caution leads me to wait until a week or so after release to hear what folks are saying about it.

If you have a USB stick you’re not using you can install Mint on it and boot directly from the USB drive without modifying your actual OS, and see how you like it! The same is true of many other linux distributions if you’d like to explore, but Mint was my own first foray into linux and I think it’s a comfy distro to start off with. I think you’ll be shocked by how snappy it can be on a lower spec machine like that, even running from a USB stick.

Maybe all of those PhD students would have their time better spent on this task than pretending, as if often the case, they’ve done some original work on an important theory that’s found something “for the first time”.

I mean I’m personally biased as a PhD student myself, but I think this is a great idea. I made the core of my project to basically take a picture of a phenomenon that has been inferred from spectroscopy but not observed directly. So verification, not exactly replication, but same idea. Turns out that doing something like this is very hard and makes a worthy PhD project. (I haven’t managed it yet, and am starting to wonder if my eventual paper might actually end up being in support of the null hypothesis…)

But I’m also not looking to go into academia after I graduate, so I’m not to worried about trying for something high impact or anything like that. I think for someone angling to be a professor the idea of a replication or verification project may be a harder sell, which is largely down to the culture of academia and how universities do their hiring of post-docs and such. I mean, even in this case more people are still going to be familiar with the names of Lee and Kim than any of the researchers who put in work on replication studies (can you name any of them without checking the article?).

tl;dr definitely a worthy goal and replications should absolutely be encouraged, but it’s going to take a while to change the whole academic culture to reinforce that they’re valuable contributions.

realChem, 10 months ago

I agree completely, especially about the negative knock-on effects on the quality of science overall. Making replications worthwhile for researchers to spend time and money on is certainly going to be a challenge that the institution of academia will need to figure out sooner or later (fingers crossed for sooner, but realistically probably later).

Good luck with your PhD too! I hope it’s going well so far!

…sip delicious iced coffee all hot summer day long, until you jitter yourself into bed and realize that wasn’t conducive to a restful night’s sleep.

Relatable content!

On that note though, I have a lot of coffee that’s past its peak freshness (I was gifted a bunch of beans at once) which might be good for making some cold brew…

realChem, 10 months ago (edited 10 months ago)

With all due respect to Penrose – who is indisputably brilliant – in probability when you start to say things like, “X is 10^10^100 times more likely than Y,” it’s actually much more likely that there’s some flaw in your priors or your model of the system than that such a number is actually reflective of reality.

That’s true even for really high probability things. Like if I were to claim that it’s 10^10^100 times more likely that the sun will rise tomorrow than that it won’t, then I would have made much too strong a claim. It’s doubly true for things like the physics of the early universe, where we know our current laws are at best an incomplete description.

realChem, 10 months ago

Automated drug discovery is a very interesting area at the moment, especially for cases like these where you’re confined to a relatively small subset of possible biomolecules. This kind of thing works much less well in other kinds of settings where the process chemistry can vary wildly between seemingly similar compounds. It’ll be neat to see how far they can take this idea!

The one for dispersion feels fishy; is dispersion really expected to be measured by the square root of length?

Yeah that’s a pretty standard way to do things for all kinds of random walk processes. You don’t pick up error at a constant rate with distance, as you can go either forward or backward and will often be undoing dispersion you’ve already accumulated. The most likely outcome after any distance is always for you to be exactly back where you started. However, as stated in the video, the expectation value of the root-mean-square distance from the origin (i.e. how far from the origin do you end up on average) for a random walker after N steps is the square root of N. There’s a quite good explanation on this page.

If you really dislike having the square root in there you can of course square everything to get rid of it, but at the cost of your other dimension being squared. I’d personally argue that it’s a lot easier to get a physical intuition from the ps/sqrt(km) units (you can expect to pick up dispersion proportional to the square root of the length of your fiber) than from ps^2/km (which to me just looks like inverse acceleration). The latter is valid though. In fact, if you type that into Wolfram it’ll tell you that those units are physically interpretable as the “group velocity dispersion with respect to angular frequency”!

A way that I’ve found to avoid “cursing” units is to always include what they refer to

I actually have a very neglected side project to build a little calculator app that treats units this way, where you can label them to avoid letting them cancel out. I might get some time to work on it in like a month? Or maybe I won’t get around to it until after I graduate, we’ll see 🙃

That’s really interesting! I read the abstract but I don’t really follow exactly what it is they’re proposing (and I don’t really expect I would follow even if I tried to work my way through the actual paper). It’ll be interesting to see whether other astronomers and astrophysicists take up this new model or not in the coming years though!

realChem, 11 months ago (edited 11 months ago)

I basically have a layman’s perspective here, but just based on the abstract this particular paper doesn’t seem to be challenging the idea of a cosmological constant or the big bang as a thing that happened. Looking at the author’s other works it seems like he’s pretty big on the idea that the values of physical constants may have changed over time, which it seems like is basically his argument here too?

I’ll admit, though, I’ve not heard the phrase “tired light” before this morning, so maybe it’s enough of a red flag to discard the work out of hand. I don’t know.

I don’t have hundreds of hours

Don’t start with XIV then!

So what is the most recent game in the series that I can start with that is worth it to play and wouldn’t confuse a newcomer?

All of the FF games – baring the ones that are explicitly sequels, like X2 – are totally separate from each other, you can jump in anywhere. At most you might miss some references or easter eggs.

If you want the most recent then, that’d be XVI, although I’d personally recommend looking up what the gameplay is like in the different games and starting wherever you feel you’ll have the most fun! There are some weirder ones out there, like crystal chronicles (my own first final fantasy game) and tactics, so you have a lot of options!

realChem, 11 months ago

There’s also a lot that you can do within the bounds of more traditional architecture to control heat movement, and which are easy to retrofit onto existing homes. For example, there’s the extremely rad sounding thermal labyrinth, and also lots of things without rad names like planting trees where they’ll shade your building or painting your roof white. It’s frankly kinda astonishing how much you can reduce your heating and cooling requirements with simple and (relatively) low cost changes like those.
