I had no idea Omeleto existed. Looks like I’ve got a few weekends of watching their vids ahead of me!

Why do I find “match-3” most offensive part of that thought?

You’re right. Everything is suspiciously wordy, substance is sparse, and every headline is clickbaity. It’s like they tuned the content specifically for google, not human readers…

EDIT: Because my comment was also lacking substance: e.g. the Steam Deck review in “30 Best Retro Handhelds Of 2024 [All Reviewed]” says “Yes it’s big, and the battery life… pretty terrible”, then gives no further information about size or battery life, which seems extremely relevant to potential buyers. They wrote 8 paragraphs and shared only 3 shallow facts.

I could just be further down the path due to lucky opportunities. 20 years ago I had no ambitions beyond game programming. It was only when I got a biology-related job that learning in my free time started displacing mindless entertainment. The whole field is one big nerd snipe - there are endless opportunities where you can advance the frontier of knowledge by combining a few existing ideas and working out the kinks. The more you read, the more opportunities you see. It’s thrilling. I don’t think I can go back to non-science work.

I think the dopamine from constant learning also helps to keep my ADHD in check. If I start the weekend with some study, I’ll usually also get the housework done. If I start with a video game or TV show, I’ll probably spend the rest of the weekend stressing about my todo list and not getting anything done.

I honestly don’t know what that silence would be like. I’ve spent my programming career jumping between domains, becoming an expert then moving on to find a new challenge. Now I’m building AI stuff for medicine.

In my down time I learn languages, watch videos about physics and math, and play puzzle games.

My brain actually won’t let me stop. Boredom = pain.

Since it’s a natural hormone the body already has ways to get rid of it. It has a half-life of less than an hour. The lethal dose is so high we haven’t been able to intentionally kill animals with it: “Melatonin is not fatal even at a dose of 800 mg/kg in animal studies”.

The big risk of ongoing high doses is becoming so dependent on it that you wake up as soon as it wears off (e.g. after only 4 hours of sleep). At this level you basically can’t sleep without it and have to slowly wean yourself off to get back to normality.

I think the big difference between people benefiting at small doses (~0.3mg) and large doses (2+mg) is that the 0.3mg group use it for sleep quality through the night, whereas the 3+mg people just need the sudden shock to get to sleep in the first place.

The drawback with big doses is that your brain becomes less sensitive so your naturally-produced melatonin might not be enough to keep you asleep for the whole night after the pill wears off. It has a very short half-life in the body (under 1 hour), so there’s no way for a single dose before sleeping to last 8 hours. We naturally produce only 0.06-0.08mg per night, so it’s easy to see how supplementing melatonin could desensitize someone and cause them to wake up after just 4-6 hours of sleep.

I have ADHD and am in the large-dose category and use 2-3mg of melatonin to help me fall asleep. Without it, I can’t sleep reliably because my brain often won’t shut up. Sleep reliably is so much more important to me than sleep quality.

Using it only 5 nights a week, I’m not significantly dependent. I can still sleep without melatonin, just less reliably. I’ve tried 0.3mg, but it felt the same as taking nothing.

For me, 10mg would be excessive and probably harmful in a desensitizing way. The most I’ve taken is 6mg, but it only helped in 2 out of 6 times. The other 4 times my brain just wouldn’t stop. If doubling my usual dose didn’t help, I don’t think doubling it again would be any different.

There are however studies with higher doses, e.g. this one about kids with ADHD that says:

two-third of the patients responded to relatively medium doses (2.5–6 mg/d), whereas doses above 6 mg added further benefit only in a small percentage of children.

so I guess it’s different for everyone.

I tried Bard again today, hoping it had been updated to Gemini. Not yet, but it was a strong reminder that Bard is appallingly bad.

It hallucinated entire Google products and thought Q** was an upcoming Google AGI. I asked it to use its YouTube extension to find me some videos and the extension failed so the model just made up a list of nonexistent videos by real channels.

Yes! Scientific trials have shown that for most people, 0.3mg of melatonin gives better quality of sleep than 3mg.

I’ve seen pills as high as 10mg on the shelf and have to wonder wtf they’re for. If you take too much your body becomes less sensitive to it and you become dependent on supplementation. 10mg is definitely too much.

That was directly in response to:

those are helpful altho the name of the game is also brightness

Every night I lie in bed, lights off, using my phone for about 20 minutes while waiting for the melatonin to kick in and my brain to calm down. In a dark room I have to keep my phone on quite high brightness (about 1/3rd of maximum).

Lamps aren’t an option at that stage as usually my husband is in the room also trying to sleep. I also find that “warm” light still has too much blue

Yes. They’re very effective at making me sleepy, but have 2 big drawbacks: they’re uncomfortable to wear in bed with your head on a pillow, and complete monochromaticity seems to ruin any enjoyment you get from using your phone. If I get bored it’s much harder to get to sleep because my brain starts fixating on stuff and making me anxious. Yay ADHD.

Unfortunately I have to keep my brightness quite high. My eyes can’t focus well in the dark.

I do. I also messed with the iOS accessibility settings to color shift even more. It helps so much.

I even went to monochrome red at one point and it felt like me cellphone was actively putting me too sleep. Unfortunately monochrome also kills a lot of the enjoyment of using a phone. I was getting sleepier, but felt so bored I just wanted to find something too do to fill the dopamine void.

Melatonin

I can’t do sleep hygiene. My cell phone is the first and last thing I see every day. I stare at screens all day for work and for leisure. With moderate melatonin use I can somehow maintain regular and restful sleep.

No side effects if you use it responsibly (e.g. 5 days on, 2 days off, stick with low doses). Very safe. Can improve sleep even if you’re already sleeping well. I don’t know why more people aren’t on it.

In two languages I’m learning, German and Chinese, I’ve found it to suffer from “translationese”. It’s grammatically correct, but the sentence structure and word choice feel like the answer was first written in English then translated.

No single sentence is wrong, but overall it sounds unnatural and has none of the “flavor” of the language. That also makes it bad for learning - it avoids a lot of sentence patterns you’ll see/hear in day to day life.

Thanks! That’s a well-written paper. I don’t know why I keep falling for science journalism’s simplified explanations.

I’ve so-far only skimmed it, but to answer my question they find light dark matter to be the simplest case (I didn’t see a specific range, but they used 250keV as an example), but they also considered a scenario where “dark-zillas” (mass >> 10^10 GeV) are plausible. At least that still narrows the search space a bit 😅

Sadly archive.li seems to be in a broken CAPTCHA loop, so I can’t see the full article. However, I’m struggling to imagine a fundamental universe-spanning interaction that triggers weeks after the big bang, given that the universe has already expanded/cooled enough by 20 minutes to stop fusing nuclei. If there is evidence for a Dark Matter big bang for weeks after the Matter big bang, surely this must have some extreme implications about the possible mass range of DM particles?

One thing nobody seems to be talking about: Just like String Theory, the more new phenomena are needed to make the Dark Matter model work, the further we stray from the edge of Occam’s Razor. While all the research into detecting hypothetical particles has been fun to follow, I can’t help but feel we’re just a few equations away from discovering that the universe is actually pretty MONDane.

With teacher hours, isn’t that still often over 40 hours a week?

As someone with untreated ADHD, I absolutely don’t feel I’m the highest level of control in my brain. I can make all the plans and decisions I want, but I can only gently steer what I ultimately end up doing and paying attention to. My “executive function” wields ultimate power and not only can overrule me, but also prevent me from having the thoughts I want to have.

Another indicator that I’m not the only consciousness in here: anxiety-inducing events like deadlines and exams can give me physiological symptoms even when I’ve forgotten about them. I’ll just be sitting there wondering “why is my stomach upset at me?” and only later realize it’s from stress for an upcoming test I hadn’t paid attention to.

They’ve had days to prepare this response. They didn’t rescind or explain the one thing that people universally hated, which means they’re just stalling and trying to save their reputation without actually changing trajectory.

We’ve seen this corporate bullshit so much in recent years. No more “benefit of the doubt”.
