> Acetaminophen use during pregnancy was not associated with children’s risk of autism, ADHD, or intellectual disability in sibling control analysis. This suggests that associations observed in other models may have been attributable to familial confounding.

To spell it out: the study’s point (sorry, “Conclusions and Relevance”) is to explain away the very data GP cites?

(I was replying to a child comment on fear of deep waters, seemingly deleted?)

I’ve heard this sentiment before, and can sort of intellectually follow, but man. I love scuba diving, I love the ocean and its varied and alien and multi-scale inhabitants. I’ve spent weeks on a live-aboard boat explicitly to seek out megafauna like sharks and rays (same subclass as sharks).

When I start my descent, I love to turn around and see my exhaled air bubble up, up towards the sun rays in the top layer of the water that slowly fade further away as the pressure on my ears builds and I enter the unknown ocean. It’s the most relaxing feeling, and I often remember it to go to sleep.

How beautifully individual our preferences can be. :-)

This seems like an unusually good time to mention https://hnrss.org I’ve been quite happy getting replies to my HN comments as an rss feed!

No affiliation, just a happy user. Also not trying to say you must use sth like that or anything, just a piece of software I’ve enjoyed. :-)

The first Distill publication[0] made tasteful use of minimal interactivity through JavaScript/d3.js[1] on top of SVGs. Many of the illustrations were initially drawn in GUI editors.

(Outstanding work by Shan Carter; it’s what I first saw of his style and it’s what made me want to join his team.)

And what else did Apple do? Build two “Pro” phones with even bigger batteries for these folks. Come on, let a thousand flowers bloom!

(Yeah that phrase has unfortunate Mao-era baggage, but personally I really just want the mini series back—which many also consider to have too little battery capacity—so I feel encouraged by Apple broadening the iPhone lineup.)

You seem to sound dismissive, and it did sound wild to me too, yet that is indeed happening and well documented. The “wires” are kilometer long thin fiber optic cables that are spooled off the drones. See for example: https://www.businessinsider.com/unjammable-fiber-optic-drone...

I’m not disagreeing, but the magical difference to me seems that Apple _users themselves_ decided ahead of time to trust Apple, whereas _the developer_ would make the decision to trust a third party? (My more jaded view is that such arguments are merely rationalizations, and that in 90% of these cases it’s mostly about which stack the people building an app have previous experience with… even though they explicitly claim the decision was made on technical grounds. ¯\_(ツ)_/¯)

New comment by ludwigschubert in "Fairphone 6: Nothing works without a screwdriver on the new fair smartphone"

ludwigschubert — Wed, 25 Jun 2025 15:51:08 +0000

“On the Fairphone 6, the battery is firmly screwed in. With the predecessors, it could simply be removed.”

Still awkward to turn that into the headline when it’s such a minor part of the review. The article was “translated with technical assistance and editorially reviewed”, but it’s just as off in the original. Maybe headline chosen by an editor, not the author?

Hm, I’m not sure from your comment if you’ve seen this: if you scroll down on an app’s App Store page, there’s an “Information” section with an “In-App Purchases” subsection that you can expand to see all In-App purchase names and their associated prices.

Are you also on a mini? ;-) Just because I really like bivector.net, despite its questionable web design choices: zooming out one level should make it so the animated “join our discord” no longer causes reflows. This should be fixed, but as a workaround until then for those of us on slimmer viewports…

I used to be upset at such absurdities. Now I try to appreciate what a relatively universal interface images are instead! :D It doesn’t matter how text gets drawn if we OCR it. (Though I feel better when we do so on device.)

An abbreviation for “signal-to-noise ratio” that imo should have been StNR or simply S/N. (Thus I sympathize with not parsing it immediately — it is widely used, though, so it is good to know.)

Here’s a chart of Germany’s energy mix over the last 30 years:

https://ourworldindata.org/grapher/share-elec-by-source?time...

Looks like coal usage for electricity production indeed only went up for ~3 years around 2011, probably we can consider that a mere blip within the downward trend.

Wind and solar indeed seem to pick up what nuclear used to bring to the energy mix. Gas usage is only slightly up over 30 years, which doesn’t look like it’s directly substituting nuclear — but surely it could have gone down had nuclear be kept around?

(Personally, I wish politics would have pushed harder against coal and simply ignored nuclear for a couple more decades. But political feasibility is important ofc, and I don’t know how hard of a sell that would have been in 2010.)

I filled out a profile to 80%, hit back accidentally (Safari keyboard shortcuts for back/forwards are apparently the same as default macOS beginning/end of line text editing shortcuts? And a textfield I thought had focus didnt'? Not 100% sure.), and found the entire form empty again. If there ever is a place where state saving using sth like sessionStorage is vital, it's such long-form forms.

I imagine your friend is genuine. During undergrad/before 2014 I attended a summer school (https://www.jass.school) in St. Peterburg. I found the city to be welcoming, almost European in ambiance, with friendly university students. It never felt too foreign or unsafe. In my experience, St. Peterburg is as distinct from how I imagine Moscow as San Francisco is from Dallas, Texas.

(edit: I have no idea how it’d feel nowadays, and won’t visit Russia atm either.)

You’ve completed a cursory google search and don’t understand why our leading explanations for the observations cosmologists have made say what they say — OK. Sometimes when our opinions counter the narratives of whole scientific fields, it can be helpful to first convince yourself you actually understand what they claim: what is the evidence, and what are the required inferences to arrive at the modern cosmologist view of what the universe is made of.
