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)_/¯)

“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.

Yeah, in ballroom one takes a break between songs iirc. (It’s been a decade or two.) The harder styles of dance and deeper kinds of house music seem designed to put you into a mild trance, thus the need to keep the rhythm consistent.

For D&D, have you seen https://tabletopy.com/ ? I think I saw it here on HN a while ago.

A large part of the “value” a DJ brings is track selection; for sure. Playlists can do part of that, say to create a certain mood. But DJs get to adjust these on the fly as they observe the crowd reaction. Additionally, DJs rarely play full songs. Transitions can be drawn out over 16,32,64 bars, taking 1-2minutes. During that time DJs use tools like EQs or stem splitters to ensure the two tracks playing don’t clash. There’s lots more detail; just take my strongest recommendation to try DJing on hardware with a friend at some point; it’s a richer and more rewarding experience than the “Skrillex pressing play on his MacBook” meme suggests.

Edit: there’s lots more to say about DJing of course, maybe someone else will chime in. One aspect to keep in mind is that DJing is important primarily in dance music. If you don’t go dancing at clubs you may not be aware how different dance music is to traditional music meant for listening. A lot of the focus of dance music is generating tension (“build”) and releasing it in a pleasant manner (“drop”). Doing that at a pace that works for the energy level of the crowd at that moment, without unexpected shifts in energy levels, is not trivial. It requires taste and experience, and aims to create a more cohesive and unified experience for the dancers than a playlist could.

Phew! Can you tell I recently got into DJing? ;-)

> far, far more money from services […] than from hardware.

Q1 2024 Share of Apple's revenue by product category:

Services: 19.33% Hardware: 80.67%

(Hardware breakdown: iPhone: 58.29% Mac: 6.51% iPad: 5.87% Wearables, home, accessories: 10%)

Though I’d love to know how that breaks down for actual profit, and likely they expect services revenue to grow more than hardware in the future?
