On track to having sold less than 15% of their Y1 target (400,000 vs 3 MM), production deliveries slashed, and the reported shareholder near-revolts, I think it's clear that the Vision Pro has flopped and there won't be a sequel any time soon.
A very well known stable case is the restricted 3-body problem. It is where one of the objects out of the 3 are so light that you can ignore it when calculating the orbits of the other two.

It is of practical use often with spacecrafts, where the spacecraft is much much smaller than the Sun-Planet or Planet-Moon it orbits around. Jokingly one could say this is why you don't need to worry about the Sun-Earth system blowing up every time we boost the international space station to a higher orbit.

So, a developer should spend ~$5000 with no chance of ROI on the off chance that at some undefined point in the future this will pay off when they would have to spend another ~$5000 developing for the newer/cheaper/whatever device?

My favourite debugging technique is "introduce a known error".

This validates that your set of "facts" about the file you think you're editing are actually facts about the actual file you are editing.

No one who is in engineering would say something like this. I can only conclude your job is auxiliary to engineering. In which case: I don't think someone who isn't an engineer should be talking about what is and isn't possible with respect to how engineers work. It's also a good idea that when engineers do tell you how they work -- not to ignore everything they say. Since Afterall -- you're not actually the one doing the job.

This idea of extracting water from air keeps coming back, but every time someone tries it, they learn of the same thermodynamic limits. It is extremely energy-intensive to extract water from the air, and it only really works if the climate is humid enough that there is water in the air to extract. This is exactly what a dehumidifier does, and the off-the-shelf version you can buy at home depot is no more than 5-10x worse than the thermodynamic limits - those generate a pitiful amount of water for a lot of energy intake.

I was a philosophy major in college and semantic quibbling over Gettier problems was popular while I was there. I have always believed that Gettier's popularity was due to the fact that the paper was only three pages, and therefore it was the only paper that the academics actually read to the end. I never thought there was anything particularly deep or noteworthy about the problem at all - it is fundamentally a debate over the definition of knowledge which you could debate forever, and that's exactly what they were doing - arguing about the definition of knowledge, one 30-page paper at a time.
I think a relevant gap you may be underestimating is "if you finish your solder job and it just doesn't work, what now"?

Just getting some melted metal onto a thing is really ~none of the skill cap that makes it "scary", when it inevitably doesn't work, the skill involved in debugging it, fixing the issue (desoldering), identifying if you fried other small cheap components that may need to be replaced, that's really the part that makes soldering a scary skill.

FWIW I think this is an example of a broader class of "being a beginner is much harder than knowledgeable people think"; if you're skilled then you also actually don't make nearly as many basic mistakes to begin including the connection being bad, accidentally shorting, wrong polarity, wrong sized component, and you'll recognize something might be problematic right when it happens. That means you don't even need to do noideadog debugging when a beginner must.

You can probably imagine doing "carefully solder and just fail the project if it still doesn't work at the end" being a strategy that would have a pretty good success rate, when it would actually have a dismal project success rate for an actual beginner.

There’s a current trend of obsession with “data driven” or “evidence based” assessments. While measured data from reality is useful, it’s not without its own sets of flaws. Much data may not be representative or usefully representative of reality due to complexity of the situation (what we measure isn’t isolated or cant be easily linked, or our measurement process itself is flawed). The sort of pinnacle of relying on data assessments is the assumption of removing bias, which is often simply not true.

Not only is bias introduced from accidental collection flaws, it’s also often tampered with intentionally cherry picking data, choosing interesting data or in some cases flat out falsifying data. In addition, evidence based reasoning often suffers from there being a lack of evidence to make a decision from. Or in some cases some critical aspect surrounding the decision is very niche to the case so the data may not take that into account unless it’s highly tailored data (evidence based reasoning tends to focus on breadth of applicability because gathering evidence is a long and often expensive process).

There’s still a lot of place for using theory and reasoning in conjunction with or in absence of data. Things like experience, professional opinion, etc. Medicine should be no different in that regard to any profession. The key is of course to always strive for sound empirical evidence/data where possible, but to use sound documented reasoning and theory in its absence if you want the best objective results.
The question is about waiting, i.e. when you have no real work to do. If you have significant work to do then there is no point in sleeping until that work is done.
>> Sorry, Do you mean to the audio for this text is not good?

No, the audio was OK or even good. The example seems to be an automated response from some system where a human has just placed an order. The order number is A123B567Z890X but if we want our system to "read back" the order number we apparently have to specially format the text. I suppose for the clarifying stuff "Alpha Bravo" that's a good idea, but separating digits and all those commas?

Don’t get discouraged. This is a good opportunity to dabble in each of these areas and this is a project that the author shows will work, so you can follow the recipe. There’s some up-front investment for tools, but you may find it fun and challenging.
> I think in this sentence, there's a hidden assumption that most projects look like your project(s). That's likely false.

You left out the part of that quote where I explained my assumption very clearly: A decently designed system.

In my experience if you cannot split tasks into <1 week the vast majority of the time then your code has massive land mines in it. The design may be too inter-connected, too many assumptions baked too deeply, not enough tests, or various other issues. You should address those landmines before you step on them rather than perpetually trying to walk around them. Then splitting projects down becomes much much easier.
Also they still have drivers in the Las Vegas tunnels I think which is something crying out for automation.

Realistically people were making these kinds of points back in 2015, and now a large percentage of the lists of unicorns were from somewhere around 2015. It just takes time for most of these companies to become well-known unicorns. The last five years is always the worst five years, until you wait another five years and in hindsight consider it a golden era.

Edit: although I do think that the couple years of high interest rates will slow the growth of startups from this era, since it has a meaningful impact on how much cash VCs can spend. The AI boom at the tail end of high interest rates will probably cover a bit of that though; OpenAI is the first runaway success but I'm pretty sure it's not going to be the last.

You could say the same thing about Apple. Would Apple have turned around if Jobs hadn't come back?

Apple was near bankruptcy, was on the way out.

But, Jobs did come back, and now it looks pre-destined. Like some story book of inevitability. But was really not a sure thing at all.

If the right leader had taken over Sears, who knows. Sears had the history and background to do what Amazon did. The Sears Catalog is still known as an Icon. If that had been parlayed into the Internet Sears Catalog, things could have been very different.

Adobes use of AI is embarrassing. Try it in illustrator or photoshop.
I would dispute your definition of "justification". I would also draw a distinction between "definition of knowledge" and "knowing that you know". I.e., that you know that the viewer doesn't know, even though he thinks he knows, is itself grounded in justification (here, the knowledge that you have put up a fake background).

I could just as easily construct a problem in which I quietly turn off your background, which would mean your Zoom partner does possess knowledge while you do not, even though now it is you who thinks he does.

Sleeping for 100ms between checking for events will not produce a noticeable CPU load. The only reason this would drain the battery is because it can prevent the CPU from entering deeper powersaving states - but even for that 100ms is an eternity and video streaming will prevent that anyway.

A casual look at the source shows the architecture won't allow the attacks you're talking about. Since each request runs separately, there's no way for prompt injection on one request to influence a future request. Same thing for leaking history.

Thank you for your submission of a proposed revolutionary theory to replace dark matter. Your new theory claims to be superior to dark matter models and will transform our understanding of the universe. Unfortunately, your theory will likely fail, because:

[ ] It cannot explain galaxy rotation curves across all galaxy types.

[ ] It fails to account for gravitational lensing observed in galaxy clusters.

[ ] It cannot explain the Bullet Cluster observations where dark matter appears separated from normal matter.

[ ] It is inconsistent with the cosmic microwave background anisotropies.

[ ] It cannot explain the large-scale structure and formation of the universe.

[ ] It introduces arbitrary parameters without physical justification.

[ ] It lacks a sound theoretical foundation or violates established physics principles.

[ ] It fails to explain the observed velocity dispersions in dwarf spheroidal galaxies.

[ ] It cannot account for empirical relations like the Tully-Fisher relation.

[ ] It cannot be tested or falsified by current or near-future experiments.

[ ] Your claims are unfounded or exaggerated.

>certain, deterministic, non-bayesian primitive model of our bodies

What makes you certain the model of our body is non-Bayesian? Does this imply we have an innate model of our body and how it operates in space? I could be convinced that babies don't inherently have a model of their bodies (or that they control their bodies) and it is a learned skill. Possibly learned through some pseudo Bayesian process. Heck, the unathletic among us adults may still be updating our Bayesian priors with our body model, given how often it betrays our intentions :-)

Looking for help for Bloxtor: A Free Open-Source Web App Framework
Hi Hacker News!

I’m excited to announce my latest project, *Bloxtor*—a free and open-source web app framework designed for No-Coders, Low-Coders, and Coders alike.

### What is Bloxtor?
Bloxtor simplifies web development by transforming code into visual environments and vice versa. It aims to make development more accessible to everyone, regardless of their technical background.

### Why I’m Reaching Out
As I continue to develop Bloxtor, I’m seeking feedback and contributions from the community. Here are some specific areas where I’d love your insights:
- *User Experience*: What features do you think are essential for a web app framework?
- *Testing and Feedback*: What are the best practices for gathering user feedback while testing?
- *Feature Development*: What additional functionalities would enhance the framework?

You can check out the project and contribute on GitHub: [Bloxtor GitHub Repository](https://github.com/a19836/bloxtor).

I’m looking forward to your thoughts and suggestions. Thank you for your support!

Others have answered on one level. I want to answer on another.

A few older crypto mechanisms were designed around trusting one thing totally. For example, everything's secure until the end of time provided that the user keeps a private key totally private at all times, with no interruption, ever, and if the user lapses then the overall mechanism breaks really badly.

They were complicated mechanisms held together by a screw made of a metal which was assumed to be infinitely strong.

The current fashion is to trust thing in a more limited way, and to design systems such that they won't blow up spectactularly if something breaks. Being able to revoke keys is part of that, it is a weakness that helps to avoid a really bad weakness.

https://www.uploadvr.com/non-pro-apple-vision-headset-report...

Meta is having enough trouble attracting developers with hardware that's an order of magnitude cheaper and has two orders of magnitude more units in the wild. They got through the first hurdle of convincing people to try VR but keep falling at the second hurdle of user retention, headsets that are gathering dust in a closet don't make any money for developers.

Apples decision to go all-in on hand tracking compounds the software problem even further because the vast majority of VR software that has already been developed is designed around controllers with IMUs/buttons/sticks/triggers/haptics, and would be very difficult to port over to the Vision Pros much more limited control scheme.
Programming languages are quite uninteresting and not particularly notable. What ended up being so horrible about the codebase that you couldn't take any developer and throw them at the code?

Why do people lionize trying ideas that are known to be dumb and/or impossible? Is it because we just no longer believe that things truly are impossible (or dumb)? The ideas that all turn out to be "impossible" successes are ones where the math or physics bears out the idea but the engineering is "impossible."

Hyperloop (and vacuum train systems for the ~100 years they were called that before the Musk rebrand) had physics problems, and no matter how hard anyone tried, they were guaranteed to run into them. Cargo airships also have a physics problem that make them absurdly expensive and risky to put cargo on. In both cases, this is an idea that is 100 years old and where the physics has been studied. This time is not different unless you have solid reasoning.

Contrast that with rockets, to use another Musk example: Rockets are well within the bounds of physics, but a hard engineering problem. Landing a rocket propulsively was also known to be an "impossible" engineering challenge that was first demonstrated in the 1990's (with too low reliability).
