> car infrastructure may solve some needs, but it is in direct conflict with other needs

True for all infrastructure choices

> the physical space required for that alone is an unbelievable double-digit percentage of the city area

True, and I do miss big city life, but all the major cities have been captured by anti-development fanatics of a particular political bent vehemently opposed to me, people like me, and our priorities.

Conclusion: double-garage areas work best for my mix of requirements.

This post and the discussion is great!!! Brings me back to 2 different projects/products that I developed that never made it to market (2009 and 2014). I also kept a log of ideas most of which withered in the light of day but a few persisted. And for each project I went off to live in a cave and code for a year (not recommended). Looking back I absolutely should have shared what I was working on and found support from a community (highly recommended). All of these ideas are excellent. Thank you for sharing them.

This was openly crowdfunded in Japan. Please explain the lie/scam for us? How does Makuake rip people off?

Is this comment anything more than the normal shit HN negativity?

Nihilism is so cool, thinking is so hard, if I try I might fail.

Sure you might be right. Just want to know where the scam is here?

> Oh, I didn't mean to touch a sore spot

There's no sore spot, though you definitely tried to find one to touch, or at least that's the only way I can rationaly explain your obsession with posting troll comments in every Rust threads for years. Which ends up getting annoying even if every single comment misses the mark.

> 10+-year-old language with less than 2% market penetration is unlikely

You seem to fail to realize that there's very little market for unmanaged languages at all. I don't think C or C++ have more than a single digit market share percentage each in 2025 either.

For most programming tasks, JavaScript and PHP are good enough and there's no way you're going to use Rust (or even Java) for those.

> I wonder what someone who reads the numbers as "Rust pretty much won" would make of, say, Go's success, that is, at best, moderate but disappointing; still well behind Ruby

Go's success is very solid compared to pretty much every language invented in the 21th century, but ultimately it fights in the same category as the mainstream giants so it's hard (read: impossible) to really become dominant.

Rust on the other hand is targeting a much narrower niche where the competition has been crippled by security vulnerabilities and poor developer experience, but also has much stricter performance characteristics, which served as a moat for a while.

For its niche, Rust has definitely won the status of “it's the future and we must use it as much as we can from now on” (though for its niche, the code tends to live much longer than for the disposable “app” code, so Rust isn't going to replace the existing C or C++ this decade or the next, and that's fine).

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.)

Go read the emails the administration was sending to Twitter demanding people be taken down left and right. Or if you want a wider view than just the US, look at what European governments demand from social media companies. It's all censorship of the right by the left, zero in reverse.

But it's true that the left does not need to overtly threaten from the top as much because they already purged all the institutions of anyone who would resist them, so they can just coordinate directly across institutional lines. They don't need to threaten when they have plenty of insiders willing to do the work for them for ideological reasons, without being threatened.

These improvements could be laying the groundwork for future products. Engineering wins in this regard are almost never useless - that’s a short sighted take imo.

But I agree this iphone air as a product is kind of weird. Similar to the original macbook air maybe? Ahead of its time but a bit limited by today’s tech. A peek at the future…

It's not an enforcement issue so much as it is a heavily exploited loophole. Part of the reason freight trains are so long is so that they can't fit in passing sidings. Since Amtrak does fit, they end up having to yield because the freight trains simply cannot.

Could this be fixed by legislation on max train length to ensure all trains fit in sidings? Yes. Will that legislation get passed? No.

> Even with multiple excursions, busses are optimal for getting people around because the 100s of people on the ship are ultimately going to the same places

Cruises are one of the rare cases where our buses are correctly sized and competitive against rail, in large part because you’l continuing the social experience of being on a cruise ship.

When you consider what makes a bus-sized bus perfect for tour groups and the like, it quickly becomes apparent why they’re not optimally sized for transit outside the constraints imposed by driver economics.

Yeah, maybe. Even if Brightline succeeds in building something it's going to fall short of connecting LA to Vegas.

Good reference right here.

Just because Apple is using space-grade titanium (likely Ti-6Al-4V) for the new Watch case doesn’t necessarily mean the same material or process is being used for the USB-C housing. As mentioned in the video, the scratch resistance of the watch case appears to be higher than that of the USB housing. This could be due to differences in surface finishing, post-processing, microstructure, or even different base materials. Scratch resistance generally correlates with hardness, which in turn scales with yield strength of the material.

Regarding the manufacturing method, based on the sectioned images and visible layer patterns, the USB housing does appear to be additively manufactured, likely SLM or DED, not binder jetting. However, those optical images alone don’t provide enough evidence to pin the exact AM process used. The visible "fish scale" surface texture could result from either Directed Energy Deposition (DED) or Powder Bed Fusion (PBF/SLM) since fish scale morphology is a result of remelting of the previous deposited tracks. Without cross-sectional images showing the interface between the housing and the substructure, it's hard to tell whether the part was printed directly onto the assembly (DED-fashion), or printed separately (SLMEd) and then soldered on. Even some additional simple SEM images that reveals the microstructure at 50 micron scale would give more information since DED and SLM have inherently different cooling rate that gives different grain morphology and pattern in sub-micron scale.

Worth noting that while DED has advanced enough to achieve relatively fine resolution today, DED Titanium typically exhibit higher ductility and lower strength/hardness compared to PBF, due to its beta-phase dominated microstructure as opposed to the alpha dominated structure + martensitic phase in PBF. A scale bar on the optical images would’ve helped estimate melt pool size or hatch spacing, giving more insight into the process used. As it stands, we can speculate, but more detailed characterization is needed to be 100 % sure. Cheers

I've done the same many times with the 30+ kg of gear and kid, even once going up to resupply a friend on a multi-week trip. It's good fun for your quads. Helps to put some of the heavier gear in a pair of those large waterproof roll-top bags and sling them across your chest, gets your centre of gravity more neutral.

I think live video has a bit different pattern than video on demand.

But aside from it, it should be very obvious: A) you are notified by the intellectual property holders that somebody is streaming pirated content, B) a specific customer or set of customers, who are not a known streaming service, are serving tens or hundrends of IPs with video and C) these customers do not have much activity during other times.

My point was that there several major university traditions in Europe. The differences between them are almost as significant as the difference between any particular European tradition and the American tradition.

The UK is a particularly poor example of how things are done in Europe. In many aspects (such as whether the primary university degree is Bachelor's or Master's) it's closer to the US than the average continental European country.

You edited your comment after I started writing mine. Your idea that the US is still responsible for an exceptionally large fraction of academic research sounds like a leftover from the 20th century. European universities needed a couple of generations to recover from WW2, but since ~20 years ago, there have not been any significant qualitative or quantitative differences between the research output in the US and Europe. (China may also have crossed the threshold recently, but it's too early to say.)

At least not in the fields I'm qualified to judge (computer science, bioinformatics, genomics). There are obviously major differences in both directions in individual topics, but that's because both blocks are pretty small. Neither has enough researchers to cover every subfield and every topic.

American universities fill most of the top positions in university rankings, but that's mostly because the concept of "top institutions" is more relevant in American culture. (That's another aspect where the British tradition is closer to the US than continental Europe.) In many European countries, all proper universities are seen as more or less equivalent as far as education is concerned. Some universities employ more top researchers than others, but that doesn't impact their reputation as educational institutions as much as in the US or the UK.

>It comes from the era in which it would not be expected for a vendor to patch a program they already shipped

This is still the case today. An operating system breaking apps is not desirable behavior. Not all apps are still in development, the work may have been contacted out, the development studio may have been bankrupted, the source code may have been lost, etc. Either you add a compatibility hack to the OS or you drop support for that app.

Of course, but the choice is standard and thus the answer is 9. I can define a non-standard sqrt(x) which sometimes gives the positive root and sometimes the negative one, and then sqrt(sqrt(16)) could be -2 or undefined (if I defined sqrt(16)=-4) but that's just silly - the only reasonable interpretation for what the calculator should show for sqrt(sqrt(16)) is simply 2.

It's like this Liquid Glass was "splashed" over still-current flat style - it feels like there's no visual consistency and this is some internal transitional beta software.

They did add contrast between interface elements but in some places forgot to change size of buttons to fit with the rest. Interface flashes trying to figure out if text and icons should be black or white. Sometimes it even loads some unstyled gray flat widgets and then "pours" this glass over. Some apps still hasn't changed at all and continuously use one color or mix of both like Home.

The "traffic lights" windows widget on tablet: I just hope nobody will get that brilliant idea to bring it onto desktop because it's just plain horrible. Menu bar you pull down from the edge of the screen is rather useless at the moment; doesn't seem any app already updated to utilize these. Switching from library to main sprinboard screen on tablet causes icons to squeeze together and fly randomly at either right or left corner.

We got a doubtful visual update but rubber-banding call screen, notifications that won't synchronize across devices and won't disappear until you open apps - that's still here year after year.

You'd be very surprised just how little energy a radio can get away with. We're talking energy scales where ambient radio waves are a viable source of power.

It's totally viable to have a device like this with an essentially infinite battery life. You have to compromise on audio quality, recording time, and upload rate, but you can. It's not even anything particularly crazy or difficult.

The more practical way is a remote power supply. You can get a small amount of power at a good distance with radio. Just enough to keep the recorder ticking and to charge a capacitor for transmit bursts.

It is strange to pretend that there is no cultural bias and then given an example that is usually explained because Asians seem to culturally value more education than white British.

How will you explain that Asians outperform white British otherwise, knowing that the idea that Asians and white British are genetically different enough to explain this has been scientifically debunked, or that adopted Asians don't show the same pattern as not adopted Asians?

(and, yes, of course SAT is highly predictive of college performance, isn't that the point: people who get better training get better college performance while not being "smarter", just "better trained")
Running Nvidia CUDA PyTorch container project/pipelines on AMD with no changes

Hi, I wanted to share some information on this cool feature we built in WoolyAI GPU hypervisor, which enables users to run their existing Nvidia CUDA pytorch/vLLM projects and pipelines without any modifications on AMD GPUs. ML researchers can transparently consume GPUs from a heterogeneous cluster of Nvidia and AMD GPUs. MLOps don't need to maintain separate pipelines or runtime dependencies. The ML team can scale capacity easily. Please share feedback, and we are also signing up Beta users. https://youtu.be/MTM61CB2IZc

I said "every time I try it" and I said "idiomatic Rust." The fast rust implementations are consistently starred there, indicating use of hand SIMD or unsafe or others. If you read them, they are not very idiomatic.

Also note that 3 of 4 comparisons in favor of Rust are marked "contentious" for using different algorithms with different limitations - they are not equivalents. The last one is k-nucleotide, which is a very algorithmically heavy problem where nobody has given optimized C and Rust has won at producing a decently optimized thing quickly. Note that the fastest C++ implementation handily beats Rust on that one, also.

The problem is, overtaking is one thing when you got two parallel rails and ample point switches.

But when you don't have them or only every 100km or whatnot, or any of the potential places (such as in a train station) just isn't long enough to accept and buffer a 3 miles long train... then good luck, there just is no physical opportunity for the faster passenger train to speed ahead, not to mention the absurd amount of energy wasted in braking and then re-accelerating that 3 mile freight monster.

Fixing this would be possible - either by limiting the maximum length of a train or by forcing the extension of parallel rail segments. The former makes logistics significantly more challenging plus it requires more staff (which is the real problem, long haul isn't wanted much these days, neither rail nor road), the latter is darn expensive and someone has to foot the bill - Congress certainly won't.

So funny enough, I'm sitting on a plane right now because the amtrak train was late, then announced a different trip number then what was on the ticket. No information on what was coming or leaving. It was a small city depot, but it was nothing like I've come to expect in Europe. The Chicago/Minneapolis ticket was cheap. Seats on the way up were comparable to first class. Wifi did not work on the way up. Did turn a couple hour journey into an all day affair. My kingdom for a bullet train like others have.

> On the other hand, writing code that the most junior in your team can understand leads to mediocre code.

Disagree on a couple levels. First, while the overall architecture of the system might be complex, there shouldn't be any one single function that isn't readily readable by a junior new hire. Complexity is in the system, there should be no complexity in small sections of code.

Second, the ultimate level of mastery is to be able to build simplicity. Any newbie can write a convoluted mess that nobody can understand.

The reason there are variations of the same-similar shapes all over the world is that different peoples in diverse locations saw the same “light shows” in the sky from various vantage points.

This riddle was solved 20+ years ago by Dr. Peratt and his collaborators, but I guess many more years will pass before his work on the subject is widely accepted or someone else with the “right credentials” in the social sciences rediscovers the same explanation and has better luck than a physicist who became wonderfully obsessed with petroglyphs.

Except that is not how it has played out. In science fiction, there are competing views of the future.

One view of the future is like Star Trek, where people’s needs are easily provided for by technological advancements, and people spend their lives on advancing human understanding at a species level. In other words, technology has liberated people from working to provide for their basic needs and enables them to focus on higher ideals.

In other stories, humanity is dominated by technology and a minority of people who wield it.

If you believe in a zero sum game, then try going somewhere like a community fridge, where our agricultural abundance is saved from the garbage by stores who are willing to donate. Or watch as generational wealth provides for people who will never work a day in their lives. Look at the extreme excess of PhD students working jobs far beneath their abilities, and teaching no one. Ask yourself how worker productivity and participation has skyrocketed and homelessness has too.

Zero sum is not the way I see the world. I believe gradients drive economies, but in almost every system, large gradients are unstable. Large gradients inefficiently over-allocate resources to the wrong places and reactionary effects result. That manifests in violence.

Space Station 14 is the same though but it might use some 3d stuff for rendering based on the comments in the blog about issues with OpenGL (or might just use OpenGL's 2D stuff) I know it has some 3d-ish things for visibility shadows but those might just be done in 2D, and from what I've tried SS14 (and SS13) is a 2D game.

None of the COVID measures had any effect on public health and yet they were enforced long after that became obvious to anyone watching the graphs the government themselves published. And the nature of the virus was known within weeks of it appearing - there were no real surprises from that point on. It acted very similarly to any other respiratory virus with the only differences being the unusually steep gradient in age effects.

COVID was 100% an authoritarian power grab by public health officials. Zero percent actual health. And public health is an overwhelmingly left wing and political field, being as it is the idea that health should be managed collectively.

This is why https://www.economist.com/graphic-detail/2015/10/29/our-firs... concluded that the best university in the USA is https://en.wikipedia.org/wiki/Washington_and_Lee_University.

For this they measured the gap between what graduates made, and what they would be expected to make based on high school record, test scores, and choice of major. In other words, "How much do you earn because of the university you went to, rather than your own virtues?"

That university won because it has a network rich people who could help people's careers get a good launch.

Thanks, I thought I remembered seeing these folks a while ago. From checking on Kickstarter it looks like they actually had three different ones so far.

Last Update 2020, 1,301, $844,621, Looking Glass: https://www.kickstarter.com/projects/lookingglass/the-lookin...

Last Update 2023, 8,051, $2,511,785, Looking Glass Portrait: https://www.kickstarter.com/projects/lookingglass/looking-gl...

Last Update 2025, 2,365, $680,940, Looking Glass Go: https://www.kickstarter.com/projects/lookingglass/looking-gl...

First Kickstarter had pretty positive, seems like there were a lot of delivery issues with the later Kickstarters. Still, done three of these so far with at least some percentage actually getting something eventually.

It's difficult to tell on Kickstarter sometimes, since there's a bunch that have horrible order fulfillment, and collapsed delivering almost nothing, or pulled snatch and grab rug pulls, yet there's also a lot of people who expect it's like clicking "ship" on Amazon.

The Kickstarters actually have a lot of answers to the tech questions about turning flat photos into 3D images and taking 3D pictures, and the basic tech ideas being used.
