Isn't one of the biggest problems with these VR headsets the nearness of the display to the eye? It seems like prolonged exposure to this would result in myopia that would worsen faster than it does when exposed to screens that are farther away.

At the risk of asking a dumb question - why do wind turbine blades need to be transported in one single impossibly large piece?

They are all composite materials, right? Can't they be manufactured in a couple pieces and fused together properly on-site, using technology that is a more economical as compared to designing and building new types of aircraft?
> Motion blur in passthrough mode ended up being one of the many reasons why I decided to return my Vision Pro, because it’s just uncomfortable

If I am in VR field, and wasn't very tight on the money (which I assume the author isn't), I probably will keep a Vision Pro with me even if it's a literal peace of junk just so I can play with it occasionally for my curiosity.

I wonder what's the difference between me and him.

To make it clear, this is not a loaded question but a genuine one. His decision is objectively more reasonable than mine (keeping unneeded junk around), but I just can't get it.
> I wonder what happened in the meantime to require one for my loan.

Likely the previous title policy (and now yours) specify that they only provide coverage as long as the policyholder themselves owns the property. Otherwise your lender could be mostly satisfied by a warranty deed from your mother ('s estate). That's the hook that makes it into a racket of perpetually leeching off every transaction rather than a one time expense to perform legitimate diligence.
No. Your eye is generally focusing on infinity in a VR display, that's why myopic people need to wear glasses in VR.
I made two really bad misunderstandings which I completely own. I can't seem to edit it, so please let this be my refutation and explanation of my own mistake.

First misunderstanding: I assumed this was a new large matrix multiplication algorithm building on the hype from last week or so where we saw this paper: https://arxiv.org/abs/2210.10173

It is not an algorithm, but a hardware design - a systolic array using roughly half of the silicon area of a baseline design.

2. Assuming that we were talking about an algorithm, I then further assumed that it reduce an algorithm's multiplications by half for some important n. I assumed that it did this by accelerating some critical sub procedure in the baseline algorithm into a more efficient big O class without really changing the multiplicative factor. This is a common way to reduce the number of operations of an algorithm for some fixed n. As a consequence I thought that the author must be being sloppy by not telling us the full big o details of the improvement, and just picking some n where it just so happened that half of the multiplications vanish. That also seemed unlikely to be a consequence of a improvement in the bound of matrix multiplication, given how incredibly slow the progress on matrix multiplication bound has been. So I thought that the author might even be a crank.

But it turned out the sloppy thinking was on me. I was being the crank.

Reading the paper's introduction made it very very clear that we were dealing with a systolic array that reduces silicon area per compute.

Even worse that information is there in the first sentence of the readme as well.

Would a clearer sentence have helped me? Something like:

"We introduce a VHDL hardware design for a systolic array that nearly halves the silicon area of a baseline array, by replacing half of the multiplication-accumulate units (MACs) with simple adder units, exploiting Winograd's 1967 fast inner product formula (FIP)."

I'm honestly not sure, given how bad my mistake was to begin with. Not even the diagrams tipped me off - in hind site they are very obviously hardware block diagrams, but I thought that they were just needlessly complicated algorithmic diagrams! How silly!

I still believe that the readme could be simplified for a general audience of goobers like me. But first and foremost I have to admit that I was being a goober!

Does that help you understand my mistake here? I do understand Big O and why cutting operations by half is typically a constant factor improvement. But apparently I don't understand it well enough to prevent me from retconning a narrative with some very stinky assumptions and then projecting them on to the poor innocent hardware designer. Not very proud about that.

To support copy&paste all you need is a common format for 3D objects, like HTML is for 2D documents; glTF might be a reasonable candidate.

The problem with the Apple approach is that there are no apps and games, and there probably won't be many given it's a 3500$ device with few users that Apple exerts its tyrannical grip over (or if there will be, they will be ports of Unity/Unreal, PC or Android VR apps, not using any of the special features that the Apple OS may have).
It goes both ways. Everyone is busy. Consider the following result:

(you create a ticket and then after some lengthy amount of time getting escalated/reassigned your ticket status is blocked and you're asked to call the helpdesk number at hours that suit them and not you)

That said, the wholesale profits for black market marijuana are insanely low right now. I'm seeing $300/lb for decent-enough outdoor grown strains. Places like Oklahoma allowing lots of low-regulation grow ops really could lead to commoditization of the product to the point where a lot of the weed is eventually sold near the marginal cost of production. This might in the future dissuade cartel/mafia/triad-style activity after those groups take the time to realize there's no money left in the game.

Psychedelic mushrooms (at wholesale, per pound pricing) are currently being sold for less than $1/g -- there's an incredible oversupply of that product nationally.

Ownership is hard to learn, and it is a barrier to learning Rust. However, don't confuse it with C++. Rust has two+ string types on purpose, not because of carrying 1970's legacy.

I think that kind of under sells it. Yes Apple had all sorts of existing technology they could leverage. But they still built a completely new spatial UI paradigm for it.

And an entirely new interaction model that hasn’t been seen before. Using looking at something to replace a mouse isn’t new but taking that combined with using a pinch gesture to “click“ and some of the other things they’ve come up with is a unique combination that seems to work quite well. Thought there is certainly room for improvement.

100% agree. Until this tech has the same form factor as a pair of glasses and no wires it will be stuck in the realms of gaming and porn. Not a small market, perhaps, but hardly a seismic shift in life on Earth.
Tangential, but I have a similar sardonic rant about some occurrences in Rouge One.

1. Their data storage system where hard drives are retrieved by a manually operated claw machine game.

2. Their data transmission system that requires one to use a Wi-Fi link placed on a dangerous aerial catwalk with no safety rails.

3. Their seemingly lack of off-site backups evidenced by the confidence that destroying the data center will ensure the only copy of the death star plans are erased. Which begs the questions of how did they build the 2nd death star so quickly without the original plans?

Pearl Harbor was (is?) a fully armed and operational naval base in 1942, but the stories from individuals that survived the attack, did not come from soldiers alone.

> The underinvestment into insulating old buildings was staggering when compared with Central Europe.

Nominally, GDP per capita is ~2.6x higher in the UK than in Poland ($46.5k/$18k) while domestic gas prices are only about 20% higher [1]. Renovations are mostly labour costs so the expected return on investment is almost twice as good in Poland as the UK.

Ultimately the issue is that energy prices in the UK are too low.

The problem is that by doing that they’ve limited their device’s usefulness severely.

If some kind of killer AR app shows up on the Vision Pro, could it be put on the Quest? Let’s just assume it doesn’t need a level of processing power that the Quest can’t deliver. Would the software vendor just have to implement the entire interface from scratch or with Unity or something? Are there enough platform components on the Quest to be able to do the job?

I don’t know the answer. But I did see a number of developers mentioning online over the last year just how incredibly easy it was to get started with the Vision Pro compared to the quest. If you have a Mac you sign up for the Developer program for $99 and you get an IDE, compiler, simulator, performance monitoring, full UI library plus documentation. It’s early days for some of that stuff, but all the batteries are included. From what they said it was far far easier to get to “hello world” than on Meta’s platform.

"A new poll by HarrisX, exclusive to IndieWire, found that 34 percent of U.S. adults prefer to watch movies in theaters, which means a solid two-thirds would rather wait for them to be released on streaming."

What a silly deduction. 2/3 might watch them in blu ray, or from a torrent, or from cable when and if it is aired, ppv by cable, and finally, streaming online.

Also, they don't show any serious information about the survey. It could be bogus, flawed or serious.

I’m a SWE at a Series A startup with predominantly inattentive ADHD. The need for me to jump around a bunch of things rather than just tunnel on the same area is a godsend. I struggle to really go deep or commit to long-running efforts, but if I can just jump into each thing for a few hours and constantly rotate things, I get an insane amount of work done.

Most jobs would not afford me this, but I lucked into a great role that plays into it rather than fights it.
No, people can have opinions about things that are neither glowing nor scatological.
The paper has not been peer-reviewed yet.
In your reference [1] we see that hossenfelder has worked on their own version of MOND:

"Testing MOND using the redshift-dependence of radial acceleration – Sabine Hossenfelder and Tobias Mistele propose a parameter-free MOND model they call Covariant Emergent Gravity and suggest that as measurements of radial acceleration improve, various MOND models and particle dark matter might be distinguishable because MOND predicts a much smaller redshift-dependence.[81]"

That is the theory I'm talking about.

It also seems like I exaggerated how much of the article was dedicated to MOND, which was my bad.

The article is still poor coverage of the actual research

Shiki: A beautiful yet powerful syntax highlighter
It’s kinda surprising that I’ve never heard of movie theaters doing smaller watch-a-movie-with-friends-sized theaters. No showtimes, just reserve your living room, pick among the new releases, and play. Order food and drinks and they get delivered to the room. Yes, I realized I just reinvented streaming. The difference is that it gives the theaters that exist some path forward while offering the market something closer to what they want.
If you consider the so-called Byzantines to be Romans (and you should, for lots of reasons), the Roman state was at least a notable regional power all the way from the mid 300s BCE all the way up to 1204 - that's around 1500 years. And it existed for a few hundred years more on either end.

Truly boggles the mind.
> This has nothing to do with strings

Sort of. It certainly affects strings, and you can't really use strings without understanding the difference.

My point is that its yet another thing in the big bucket of junk you need to learn in order to use rust effectively. Rust is the only language I know of that has separate types for owned strings and a borrowed strings. Its a powerful concept - and its fast and efficient for the computer. But its not "free". The cost is that it makes it harder to learn rust.

While we're on the topic - it also really doesn't help that the names of these types in the standard library are super idiosyncratic. String is to Vec<u8> as &str is to &[u8]. You just have to memorise that. How about Path and PathBuf? One of them is like String, and one is like &str. I swear I have to look it up every single time.

I think the investment is worthwhile - I adore rust. But as I said, rust feels more like a better C++ than a better C. All the pain is front loaded, with the assumption that you'll eventually write enough software in rust to make the investment worthwhile.

Simpler languages like Python or Go get out of your way immediately and let you be productive. I prefer rust, but there's definitely something to be said for that attitude.

In some ways that’s understandable and can be very helpful. Because if you’re a Mac person looking to buy a new Mac then that may be what you have. Newer Intel Macs don’t exist.

If you’re a PC user looking to switch to Mac, or you’re looking for a machine and don’t care about which operating system it has, then it’s less useful.

I’m predominantly inattentive type but focus isn’t actually my most severe symptom. That would be executive dysfunction.

I lucked into SWE being a hyperfocus of sorts, so luckily work isn’t awful if I’m not on meds, but holy cow is anything else just complete drudgery. Feels like everything is behind a wall of “startup energy” that is so hard to get through, especially without external accountability.

Rejection sensitivity is also part of it for me. I felt like I could never think fast or organized enough in the moment when talking (I would lose my train of thought in the middle of sentences), so I would get anxious coming in and try and plan, but there’s only so much you can plan for, and it just is a bad cycle to get in. Therapy and internalizing things don’t actually have that high stakes is helpful but only mostly a fix.
Purely speculation, but I wonder whether concessions only turn a profit at a certain scale.

> One way to look at VR headsets is that it's a better computer display -- as large and immersive as you want, without physical limitation. People prefer retina displays and will pay for multi-monitor setups, so we know people value this.

Except it isn't, because the density just isn't there. The PPD is incredibly low, which is why you have to make things "huge" to compensate. And while huge screens are great for watching movies, it's not great for a lot of other things. It's not comfortable to move your head back & forth just to read a line of text.

In a hypothetical future where these microled displays have 3-5x the density they do today then this starts becoming competitive with today's multi-monitor setups. Except those will also have had improvements to them as well. And even then, the number of people with multi-monitor setups is also pretty small. That's not a smartphone-level revolution or impact.
I was quite clear.

This was my main statement:

"There are absolutely all sorts of ways that private companies can be forced by the government to allow certain speech.".

This point stands and is absolutely true.

I never mentioned anything about the first amendment. So whatever you think about that is completely made up in your head, and if anything that is you being disingenuous.

Instead, I quite clearly was talking about the free speech rights in California that were covered by that court case.

Which has absolutely nothing to do with the first amendment, other than the implicit statement that yes the government can force private companies to host certain speech in certain circumstances.

So my original statement stands and you have not directly disagreed with it in any way.

> interpreted the California constitution

I am not sure if you even read my post now.
