As devices go, this one seems low intrusive burden: you have to know how to place electrodes. This is learnable and doesn't demand a clinician do it, presumably.

A common thing about writing like this article is that it confidently declares futures/promises are good for parallelism, but this is wrong - they are flawed because they introduce priority inversions.

To schedule tasks properly, you need to know who is waiting on them as early as possible. With a promise, you only know when you get to the "wait()" call, which is too late.

The correct solution is called structured concurrency.

In my opinion, the main reason[1][2] for its decline in terms of text discussions was due to the deal that Andrew Cuomo (the attorney general of New York at the time) made with the major ISPs to restrict access to child pornography. This resulted in many ISPs discontinuing their usenet offering and cutting off their customers from it.

Unless those customers made an effort to access usenet some other way, they stopped using it.

Yes, I pay taxes. I don't typically settle these kind of transactions from volatile holdings like Bitcoin or Ethereum. I use stablecoin for that, so matters of gains or losses are dealt with separately (if at all, as the case may be).

The stablecoin is not in the local currency of course, but it's not different in any practical way from handling foreign USD payments.

> If you look at a lot of the scandals that Reddit has had over the years - it was external forces putting pressure on the company to change what they allow on their service.

You could say this current upset is about Reddit management being pressured into censoring more to appeal to advertisers. What you call "controllability" is a double-edged sword.

> When there's no organization backing something, bad actors will be involved, muddy the waters and then all of a sudden the "fediverse" or whatever is associated with things you don't want to be associated with, so you either don't try it [...] or you don't promote it's use [...] - additionally, any time it's open source and self hosted, the technical barrier will be too high for a large group of people.

The same argument can be made for the Web as a whole, which despite appearances is still decentralised. When was the last time you heard a lay person say that they weren't interested in a website for their business because only unsavoury types use those?

This is an implementation problem; people will self-host (or rent from Linode or w/e) if that's simple and not too expensive, and they'll take the centralised, ad-funded option if self-hosting is too hard and/or the loss of privacy is deemed the lesser cost. While concern for privacy seems to be on the rise, ideology has never been the deciding factor for the plurality of users.

The way Apple does it, it's cleaner to implement the APIs for this sort of thing in a new operating system version, especially if it requires features not present in the current versions of the operating system.

They could make an exception for Safari by including the required code to support JPEG XL in Safari Technology Preview on Ventura to allow developers to test their sites and web apps until macOS, iOS, etc. ship in the fall.

I suspect we'll learn what the plan is as the Safari/WebKit team make more announcements during WWDC: https://www.webkit.org/blog/14203/web-technology-sessions-at...
Either you want to just get it done or you enjoy the process of tinkering on the infrastructure.

If you want it done: pay somebody a small amount to do the things. Sometimes it's even free.

If you like tinkering: pick a static site generator. Whichever one you pick will be wrong, but the process of setting it up and getting the first entries through will be a learning experience. In a bit you will have an opinion on what went well and what didn't, and be able to learn from others.

I do wonder in these conversations how many people are actual users of these things - I'm not, I got a Studio last year to manage my photography addition better, and the Pro is pointless for that - but you'd assume that Apple have talked to major Pro users, and they've said things like "oh, no for training a model I just spin up terabyte instances on AWS, why would I do that on a workstation?", or whatever.
I don't think you can solve many social and political issues with matrices and tensors, but ok.

Idk. about the Apple eco system but this always had been strange for me.

But on Android there are very clear easy to understand and explained rules about how to do material design, but somehow basically no app (including most ones from google) get it right.

My guess for the Android ecosystem is (at least theoretical) unnecessary programmatic complexity when implementing the "how", but then I'm not an App developer so idk.

The best effect this will have is drive VR/AR development, now that we have an upper spec/price: 4k+ resolution per eye, $3,499. Now the others can squeeze/converge towards that.

The closest thing I can see this being is delivering on some of what Magic Leap failed to do. I was also surprised by the lack of 3D content being described. Was there anything besides the photo/videos? I don't even recall mention of 3D movies (though maybe they were being shown but can't tell on a 2D demo video).

What it doesn't do is deliver in aspects I'm interested in. I wanted something in the Bigscreen Beyond form factor without being room-bound. The idea of carrying an entire MacBook Pro and using it is ridiculous, I should be able to use an iPhone but running macOS on it with a Bluetooth keyboard mouse. The lack of precision input makes it a consumer device rather than a creator one.
That is not a factor may have something to do with the fact the law was created before even sci-fi authors could have predicted machine learning and the huge difference it makes for creating artwork.

Generating synthetic copies of someone voice, or even combining voices (e.g. a CG voice that is a equal parts Kurt Cobain's voice and Laine Staley's voice) are also not currently a factor in copyright law, but it will be.

It would be easiest to just ban ads targeted by anything OTHER than the non-customized on page content. It's fine for ads to be targeted based on what's seen. It's _possibly_ OK to target ads by __large__ regional geographic area. (E.G. traceroute seems to say your IP is near Major Big City, so that huge region or a TTL circle around it is an OK ad pool.)

Anything more specific is ripe for abuse and should just not be allowed. Comparatively that specificity would be roughly equivalent to traditional TV, Cable and 'Print' media.

This is specificity as consumer privacy protection. I'm against most types of ads generally from a mental health stance.

More accurately, their justification was based on discredited benchmarks (which used a fairly old-even-at-the-time version of libjxl and IIRC created by the AVIF team)... and the commit to remove support was created by a co-author of WebP who gives talks on WebP and is the primary contributor to libwebp.

Sure, but as a public company they're legally responsible for the audit they signed off and while the Big 4 refuse to work with private crypto companies, Deloitte did choose to audit Coinbase.

I'm not parsing expert, but being hard to parse makes it harder to write tools that work with the language.

In China it is really common to run compressed air in PVC pipes at reasonably high pressures for large scale industrial automation. It is considered cheap and sub-ideal, but commonly seen deployed. To be fair, circular extrusions are approximately the strongest structures to apply pressure to.

One thing I found noticeable is the repeated mention of all the tech that needed to be created and is packed into this device. It seems to be trying to make up for a lack of good use-cases and justifying its price. Normally Apple's announcements tend to gloss over the internal tech-how and focus on the delivered experience.
Vision Pro supports game controllers. It was in the demo.

No it doesn’t. Parent said there were ‘plenty’. Perhaps there is another on your the list that does?
You could tap directly but a stylus was better because the ui wasn’t really touch-optimized.

And you’re completely right - they were laggy and clunky and just lacked the polish. Same as the ipod va the nomad really.

Apple weren’t the first, they just did it better.
It felt like strong "I am recently divorced, and also a parent of young children" vibes throughout. There was the value comparison to a large TV and surround sound system, which is only valid if both your home theater and AR device have the same audience size (to divide the cost by) of one person.
Most of the articles were product reviews, but I bought it for the BBS listings.
Why not do a table, but also store a table of the 1st derivative (which, for cosine, you could use the same table again but shifted)?

Then, you could do a 2nd order fit like a spline instead of a straight line between your table values.

Betcha it would be crazy fast.
Secret meta-data in a cons cell is not out of the question.

In TXR Lisp, cons cells are four pointer-sized fields wide. So one field is not used. Almost. The field is used in the hash table implementation in which entries are conses. It sticks the hash code in there. That hash code is a pointer sized word with no tag; the garbage collector can safely ignore it.

The extra field is currently not used for tracking source location information, though it could be. Source location info is instead tracked in an external hash table. (The table is configured with weak semantics, so when the code becomes garbage, the entries vaporize.)

That representation could change in the future. It would mean that when the garbage collector traverses conses, it has to look at that hidden field of each one. And each time we allocate a fresh cons cell, we have to make sure it is initialized.

I'd have to benchmark it.

Associating expressions with source location info is a cost that we bear only when processing source code. If we shoehorn it into conses, then there is some nonzero cost to all cons cell processing, whether we are scanning code or not.

An important problem is that meta-data attached to cons cells (whether internal or external) is not copied across traditional tree-structure rewriting operations.

TXR Lisp's expander does some work behind the the scenes to propagate location info, like from macro calls to their expansions. The parser has a flag for whether to attach the info to objects in the first place. It's on by default if we are reading code, but not when reading data.

Outside of the expander, a few places in the compiler have to be aware of this (when the compiler performs its own tree-writing outside of the macro framework).

Overall I'm satisfied with the reporting. From time to time I see a bug: an error occurs for which source location info isn't available but should be.

I didn't give it character precision: I think that compiler messages that report line number and character column are too rococo for my taste. If you can't figure out the problem from a line number, maybe your code is stuffing too much into one line of code.
As in, a handheld device for which developers can publish games? Because they sell quite a lot of those.
Ask HN: Are any of the AR features of the Vision Pro useful?
* All of the rooms in which the Vision Pro is demonstrated are beautiful, spacious, and clutter free. I don't doubt the people that the people who will purchase Vision Pro have beautiful and spacious rooms, but I do doubt they're clutter free. And even if they are clutter free, I would assume people would prefer a new background to look at vs a room they see every day, and would switch to full VR mode almost always.

* The ability to converse with someone with a digital version of your eyes being displayed to them seems useful for conversations that last at-most 5 seconds. After that, people will demand you take off your Vision Pros and converse with them face-to-face.

* The demoed avatar version of you for Facetime lives smack dab in the middle of Uncanny Valley. I would not Facetime with someone using Vision Pro if another option was possible, or substantial improvements were made to make the avatar more realistic

* External use of the 3d camera - The demo shows what appears to be a dad interacting with his kids while wearing the headset and capturing a moment using the 3D camera. Later he watches the 3D video he captured, reliving that moment. They could just call this feature the "Noncustodial Parent" feature, because absolutely no one is going to wear Apple Ski Goggles TM while interacting with their children, unless they are extremely desperate to draw out a few special moments into a year's worth of memories.
I think Apple kind of realizes that the naming doesn't really matter.

Even with the Intel i-series, you're not looking at the model name to make a purchase decision. You're looking at the technical specs.
I was doing a lot of playing around in Stable Diffusion when it first dropped, with scripts generating a lot- some stuff I left overnight, 12+ hour runs. My M1 Pro Macbook at doing SD inference averages about 60-70 watts, or around that I think. The inference speed is about 0.9 iterations/s (1.1s/it). Later I had time and got SD running on a workstation of mine- an HP Z840 with dual Xeons and an RTX 3090. The 3090 eats 350 watts alone, and the rest of the system sucks another 250 watts or so, for a total of 600W. The generation speed (same Euler sampler) is about 9 iterations/s.

So, 10x faster than my Macbook, nearly exactly. While using 10x the power. Utilizing larger batching with the extra 3090 vram can actually result in even more throughput.

But I find it interesting that it winds up being nearly the same in images-per-$.
>It seems to me that you could do this through sheer statistics, and have no understanding of the world you're talking about at all.

I'm not sure that there is a difference. If there is, what would be an example of true understanding vs just statistics? All of intelligence is ultimately recognizing patterns and layers of patterns of patterns.
I am curious if wearing this device for a long time will cause dizziness.
Kahan summing doesn't fix cancellation error. It just extends the precision by another 53-bits or so.

The only way you fix cancellation error is summing the positives in one variable, and the negatives in another, and do a big cancellation at the end.

Anyway, my overall point is not to criticize Kahan summing or other techniques. My point is that these techniques are incompatible with optimizations. The faster way is often times a less stable operation.
