dev_tty01··on Toyota has been developing a solid-state battery for EVs with a range of 745mi
They have sold hybrids at scale, lots of similar components, so no reason to think they can't scale when they have a design they are ready to produce. Toyota runs a huge global car manufacturing company that is known for quality and shipping a lot of cars. They know how to scale.

Toyota reminds me of Microsoft when the internet went mainstream. Very slow to respond, but once they got their giant tanker turned in the right direction they were all in. I suspect Toyota will be the same.

Actually, in US suburbia, a big portion of the population is living in an apartment with poor access to public transit. I look around all the many places I've lived and see huge apartment complexes with little access to transit. Transit has not caught up with urban sprawl in most places.

As far as EVs, if one is in an apartment with no charging infrastructure and have a relatively long daily commute, and poor charging access at the worksite, an EV is just a bad choice. If there is good charging at work, and the commute is short enough, then an apartment can work but it is still inconvenient to have an EV if you can't charge it while sleeping.

I think eventually more and more apartment owners are going to start using charging infrastructure as a marketing tool so perhaps it will get better over time.

dev_tty01··on Johnson and Johnson sues researchers who linked talc to cancer
I get the sentiment, but if I stop and think about it, I don't understand the math. I'm not intending to criticize since I struggle with this myself.

Try on this hypothetical. Imagine that ten people in a giant company called ACME made some decisions that led to 50,000 people getting hurt. ACME also employs 100,000 hard working people, representing perhaps 0.3-0.4 million family members dependent upon that income. Imagine further that ACME's other products have dramatically improved the lives of hundreds of millions of other people.

Given that scenario, does the ethical math really work for ACME to be completely destroyed? It is easy to see how the 10 decision makers should be punished. It is also easy to see how the people who were hurt should be compensated in some way. Destroying ACME entirely will harm lots of other people so it is not clear how to justify that. It is a very frustrating domain because we think of these companies as monoliths, but they are really just a large collection of mostly very decent people.

>although it is unknown whether Nobel Prize winners are more prone to this tendency than other individuals.

I think we can at least confidently say that other people are more willing to listen to an NP winner. That could completely explain the phenomenon.

dev_tty01··on Brute-forcing a macOS user’s real name from a browser using mDNS
In the early days of insecure WiFi, in apartment buildings you would see network names like "Don't steal our WiFi Room 238!"
dev_tty01··on Rapid Covid tests miss 90% of asymptomatic cases
Yep. I just wanted to emphasize that side of it.
dev_tty01··on Rapid Covid tests miss 90% of asymptomatic cases
That may be true for most, but there are many of us who interact with at-risk people (elderly parents, an immune suppressed family member, etc.) and the daily concern is whether or not I might be infectious and potentially bring harm to someone else. I don't care if I have Covid if I can't spread it to someone else.

Public service request: There are millions of Americans with compromised immune systems who are finding the current environment treacherous since most people have completely moved on. If we have an interaction with someone who is masked, it would be great if we could just mask up at least during that interaction as a courtesy. That person could be at significant risk and it does no harm to us to mask up for a few minutes to help reduce their risk even if we aren't concerned for ourselves.

dev_tty01··on SpaceX is stretching the lifetime of its reusable Falcon 9 boosters
Hmm. The pressure inside a Merlin engine is about 1410 psi (about 88 atmospheres) and the temperatures inside the engine reach 2200 C. The turbopumps in the engine spin at about 3600 rpm and produce about 10,000 horsepower, which is just used to pump fuel into the main combustion chamber. Each Merlin engine produces about 200,000 pounds of thrust and is still reusable.

Just starting a rocket engine is a complicated dance that can easily turn out badly if not handled with extreme precision. Sorry, but I don't think there is any way one can equate the complexity of a diving bell with that of a rocket.

dev_tty01··on Linux has achieved a 3% desktop market share
That’s the point. Hardly anyone uses Chrome OS, but it is still more than Linux.

I am going to assume that this is not just a troll so I will take the time to answer your question.

> technologically aware people know what Apple are doing

Yes, I do. I have over 30 years designing chips and computing systems (not an Apple employee). The Apple Silicon Macbook Pro I am typing on has great performance and I never think about battery life any more and I never hear a fan. I've owned a lot of laptops and nothing has ever come close in build quality, design, and performance/watt.

Apple has over 2 billion active devices in service. Two possibilities: We are all suffering some massive delusion, or your criteria for evaluating quality and engineering need to be adjusted.

Please name another large company that cares more about privacy, freedom, education, empowering people, the environment, diversity, etc. than Apple. They are from perfect, but they keep investing in the quest to do better. What specific ethics issues are you so concerned about?

Please answer a question for me. How come so few people who are into open source operating systems seem to be unable to understand that the vast majority of the world doesn't want to deal with all of that stuff? I think it is great that some folks enjoy the configuring, tweaking, writing their own services, setting up their shells, arguing about vi vs emacs, etc. That's really cool and I am happy that is available for those users. However, don't condemn me if I have other priorities.

It is super simple. Apple makes products. If people like the products they will buy them. If people can't do what they need to do with the product and don't enjoy using it, they won't buy it again. If you are right, Apple will soon die and your problem will be solved. If you are wrong, their unprecedented growth will continue.

Most of them do. Get on the bus, tell them your name, get off the bus and walk to the car. Key is in, trunk is open. Load, sit, drive off. Avis Preferred, National Emerald, ...
dev_tty01··on Apple plans a slow, appointment-only rollout of Vision Pro
Hmm. Are you aware that mobile gaming revenue is larger than console and PC and that the majority of mobile gaming revenue comes from iOS (iPad and iPhone)?

dev_tty01··on Apple plans a slow, appointment-only rollout of Vision Pro
>Apple was forced to abandon the Newton platform in order to compete.

They cancelled Newton in order to compete? I don't understand the assertion.

Newton was cancelled by Jobs in 1997 for a number of reasons, but mainly because Apple had lost focus and was running out of money. Jobs cleaned house and only kept the products that could bring in larger profits more quickly.

Palm pilots were sold as complementary products to Macs or PCs and synced well with either one. I don't understand how that is eating Apple's lunch for 15 years since Apple was not shipping a competing product. Does Boeing eat Apple's lunch since Apple doesn't sell any airplanes?

Apple released iPod in 2001, again, not a competitor to Palm but it did provide a means for Apple to learn how to build handheld devices in very high volumes. Ignoring the Motorola ROKR, when Apple finally entered the smartphone market in 2007, Palm began to wither away.

There are numerous quotes in the text describing the 3D API for creating and manipulating 3D content. For example:

"Present 3D content, animations, and visual effects in your app with RealityKit, Apple’s 3D rendering engine."

Not true at all.

dev_tty01··on If PEP 703 is accepted, Meta can commit three engineer-years to no-GIL CPython
Seems a bit conclusory. Doesn't this imply the community is incapable of learning from experience?
dev_tty01··on VisionOS developer docs and Vision Pro SDK
Default gestures are irrelevant. Apple always puts a huge effort into accessibility for their platforms. You are condemning the accessibility based on a tiny preview. No need to be concerned. They will have plenty of accessible options for using the device.

And a thing of tremendous utility.
dev_tty01··on Is map-reading a lost art? In era of GPS, here's what map fans say we're losing
>Maps are like script handwriting. Obsolete in practice and it's a shame.

Hmm. Not a good analogy. Script handwriting adds no new information. A 1 meter square backcountry topo map provides way more info than looking at a handheld screen. I can see big picture terrain as well as high resolution of my immediate surroundings. Completely different sense of surroundings and the information is simultaneously clear in overall layout, dense, and abundant.

It is decidedly not obsolete. I would never take an extended backcountry trip without a detailed waterproof topo map and a compass. Stuff happens. Batteries fail, screens shatter, etc...

However, you don't have to go into the backcountry to benefit from a printed map. A city map will immediately impart a much better sense of spatial relations between different points and a more immediately intuitive understanding of the routing between the points.

dev_tty01··on Cost of ‘reformatting’ prompts a call for journals to change their requirements
>No one uses latex anymore

Not true. IEEE, one of the largest professional orgs, accepts Latex. So does ACM, a huge comp sci org. I'm not familiar with others, but wouldn't be surprised if many others still accept Latex.

dev_tty01··on iOS 17 automatically removes tracking parameters from links you click on
No, they are allowing users to manipulate links. Also, this only happens in Private Browsing mode.
dev_tty01··on Web Apps on macOS Sonoma 14 Beta
And why attempt to start sending notifications if it is the first time I have visited a site? I don't know the site, I haven't had time to read any of the content. Why would I possibly want to get notifications from a site I know nothing about? Maybe if I visit it several more times in the next week or two, then ask me if I want notifications if you feel you must. Anything else is just annoying and sort of mindless.
dev_tty01··on Apple removes $99 dev account requirement for first iOS 17 and macOS 14 betas
We shouldn't forget that hobbyist programmers can write and test apps without paying the $99 fee. The tools are freely downloadable.

"You can learn how to develop apps for Apple platforms for free without enrolling. With just an Apple ID, you can access Xcode, software downloads, documentation, sample code, forums, and Feedback Assistant, as well as test your apps on devices. If you don’t already have an Apple ID, you can create one now. To distribute apps, join the Apple Developer Program."

https://developer.apple.com/support/compare-memberships

So the poor hobbyist argument is really a moot point if the point is writing apps for yourself and to learn.

dev_tty01··on Apple removes $99 dev account requirement for first iOS 17 and macOS 14 betas
I don't understand this. Why is it that we pay for the computer, storage, cloud services, etc. for a hobby but a $99 fee is somehow terrible? People spend thousands of dollars on all kinds of hobbies. Even if you get someone else to pay for the computer etc., a $99 dollar hobby is ridiculously cheap.
dev_tty01··on Vision Pro’s Big Reveal
Talking is great. Unfortunately much of the verbal spewing here on HN the last few days is just condemning, calling it stupid, making blanket statements like "no one will buy this" or other forms of diatribe with only personal bias as a basis for opinion.

Many of the people criticizing clearly didn't see the presentations.

Is there non-trivial risk of market failure? Of course. They are trying to create a computation and entertainment focused AR device. That is new. It is inherently risky to create new markets. Is it also possible that they have executed this so well that people may find it very compelling and buy it? Yes, that may be true. Only time will settle this question, so making extreme conclusory statements is just silly.

Real, open-minded discussions of the tradeoffs of the tech have unfortunately been in relatively short supply this week. Some folks have made interesting and thoughtful comments and I for one have enjoyed them very much. Kudos! More of that please.

dev_tty01··on Apple Vision Pro: Apple’s first spatial computer
Hmmm, I don't get that. Apple builds personal computers. That has been there mission from day one. This is easily the most personal computer they have ever created. I don't see how it could be more Apple.

You forgot the basic M2. As far as ordering them in terms of performance, the prices make that pretty clear.
dev_tty01··on Apple Introduces M2 Ultra
Sure, that's a story from 1983 but it is in direct conflict with facts. I have owned several powerbooks, macbooks, and macbook pros and up until fairly recently they were all upgradeable with respect to RAM and drives.
