All the major metro areas on the Acela corridor are also on a straight line, on significantly flatter land than Japan. Notice how the Acela never spends 10+ minute periods in long, deep tunnels under mountain ranges. The Acela primarily spends most of the trip going below 100 mph because it is operating on 100+ year old infrastructure that has only ever been upgraded piecemeal as it starts to fail.
It's always feels funny to me when taking the Acela between Boston and NYC that you go screaming along at 150mph... for a small portion of track in Rhode Island. The rest of the time you're going much slower. It's almost like, why even bother for that small section?
The Shinkansen was a very different experience when I took it.
I think a big part of it is also that (partly because of the necessity of building for earthquake resistance), Japanese construction is a lot more robust than American housing, and also tends to have extremely good soundproofing on windows and doors. Actually, it's most of the rest of the world, except the US.

This must be a different Japan than the one I'm familiar with, where exterior walls are often uninsulated and only a few inches thick and single-pane windows are still the norm in a lot of housing. I wouldn't be surprised if soundproofing were better for railroad-adjacent buildings, but compared to American homes the soundproofing here is surprisingly poor.

Oh, you’re definitely engaging in Magical Japan, here.
While building standards have certainly improved in the past 20 years, the average Japanese house is built just strong enough not to fall over when someone farts. In particular, windows tend to be single pane, and you’re lucky if they block a strong wind, let alone noise.
As the sister comment said - the houses are just strong enough not to fall over in a "normal", all-the-time earthquake. Our house sways a lot under typhoons and far-away earthquakes (far away = long wavelengths). It's only relatively recent that building codes have been updated to handle real earthquakes without falling over like a house of cards. Remember the Noto earthquake Januar 1, 2024? Large areas didn't have a single house still standing.
(Which is why we're now tearing down our old house and building a new, stronger one. Post-war Japan was more concerned with a) building a lot of houses, and b) keep lots of jobs, which meant, as far as houses were concerned, building use-and-throw-away houses. Then build another. And another. And don't talk to me about sound proofing.. it's non-existing. What with no insulation in walls.)
When I lived in Japan it was in a relatively recent (last 10 years) but not brand new apartment block - Maybe if you are talking about a rural area or an old postwar Showa era house, sure. But either way the sound proofing is worlds better than any new construction in the US.
I'm in a 20 year old two-storey apartment right now (while we're building a new house), and the sound-proofing isn't non-existing but not as bad as some other apartments I'm aware of (where you can't make a sound without the neighbors start knocking on the walls/floors, and you're privy to thing you don't actually want to hear..) - but we can hear every footstep when the neighbors walk the stairs to their upper floor. The rooms which are more distant are fine, we don't actually hear them talking. Most of the time.
Yikes. I also just noticed that all the plugins (part of the pro feature set) rely on separate apk downloads from the Play Store, which all appear to be dead/delisted. This is really a shame, I too have thought of this as "the best" Android SSH client in the past.
Yes, it is enabled by default (in fact this caused problems earlier on). Licensed hams (in the US) can increase transmit power (and theoretically use additional spectrum outside of ISM) but even the default "public" channel was encrypted with a known, publicized key. There was some debate whether this ran afoul of amateur radio rules against encryption, even if the key is known, since it cannot be disabled. I believe there was some progress in fixing this and allowing truly unencrypted channels for licensed operators, but I haven't checked back recently.
We frequently get juniors or interns who are perfectly capable of pumping out many LoC with the use of AI in various forms - the issue is that they _don't_ actually ever learn how to think for themselves, and can't fix problems when something goes wrong or the LLM paints itself into a corner. I have found myself doing a lot more shepherding and pairing with juniors when they can't figure something out recently, because they just have not had the space to build their own skills.
A few years later but similarly - I am still running a machine built spur-of-the-moment in a single trip to Micro Center for about $500 in late 2019 (little did we know what was coming in a few months!). I made one small upgrade in probably ~2022 to a Ryzen 5800X w/ 64GB of RAM but otherwise untouched. It still flies through basically anything & does everything I need, but I'm dreading when any of the major parts go and I have to fork out double or triple the original cost for replacements...
How can I take your comment seriously if you didn't read the article? It looks like someone didn't actually make an effort to understand the context of the images.
> Moore's law is supposed to drive down the cost of electronics
The core of the article is this complete misunderstanding of Moore's law. From there, all the rest of the confusion follows, unsurprisingly leading to the author's claim that ~$100 for a long-lasting device is unreasonably expensive.
A human working on an existing codebase does not have any special signal about what is _not_ in a codebase. Instead, a (good) human engineer can look at how a problem is handled and consider why it might have been done that way vs other options, then make an educated decision about whether that alternative would be an improvement. To me this seems like yet another piece of evidence that these models are not doing any "reasoning" or problem-solving.
I had a coworker making very similar claims recently - one of the more AI-positive engineers on my team (a big part of my department's job is assessing new/novel tech for real-world value vs just hype). I was stunned when I actually saw the output of this process, which was a multi-page report describing the architecture of an internal system that arguably needed an overhaul. I try to keep an open mind, but this report was full of factual mistakes, misunderstandings, and when it did manage to accurately describe aspects of this system's design/architecture, it made only the most surface-level comments about boilerplate code and common idioms, without displaying any understanding of the actual architecture or implications of the decisions being made. Not only this coworker but several other more junior engineers on my team proclaimed this to be an example of the amazing advancement of AI ... which made me realize that the people claiming that LLMs have some superhuman ability to understand and design computer systems are those who have never really understood it themselves. In many cases these are people who have built their careers on copying and pasting code snippets from stack overflow, etc., and now find LLMs impressive because they're a quicker and easier way to do the same.
