https://www.researchgate.net/publication/11500666_What_Geome...

The full mathematics are quite challenging, but the gist of the result (iirc) is basically: many common hallucinatory experiences, including the geometric patterns reported from both psychedelics and migraines, can be explained by the inherent connectivity patterns in the visual cortex.
Consistent with this idea, there's other strains of research (sorry, too lazy to look up more citations) that show that psychedelics tend to decrease input from the primary sense organs, so that during a trip we really are literally turning inward. (if you want to look it up, iirc the effect is called "thalamic gating" or something? the senses all come up the spinal nerves into the thalamus which helps gate our attention, but during psychedelic experiences all thalamic input is turned down.)

So what happens when you turn down the dimmer on external senses, is that you "see" only from the "higher" cortical areas: suddenly the neurons that are several synapses removed from primary sense activity are the 'loudest' in our experience. This is why "set and setting" are so important in a trip, because you're going to literally experience your mood and emotional state more strongly than usual, since it won't be mediated as much by external sensory events. That's not to say there's no external senses- most people report experiencing a sort of psychedelic remix of ordinary reality. But back to the geometric patterns -- sometimes what you see really does seem to be based on the fundamental connectivity matrix. it's like in absence of strong input, the visual cortex just has activity rippling across it along its own wiring.

anyways hopefully this rambling with a few sources cited helped a little.
you can read it using another instances, beauty of fediverse.

If Elon had kept the company public, any one with two neurons able to fire would have been shorting it and would have cleaned up. With his leadership and decision making, Twitter would have gone to 0 by now.
there's some seriously Joe Rogan-esque horseshit on that page.
> Are shareholders still to blame?

The shareholders willingly take a financial risk in pursuit of wealth. The people in the public harmed by the corporate actions did not willingly accept the risk to their health. The public people harmed were victimized by the corporation & the people involved with the corporation. If the shareholders have skin in the game, they will be more motivated to ensure that the corporation does not endanger the public in any way. The officers' fiduciary duty becomes aligned with public safety as well.

If the shareholders are simply chasing the bottom line without regard to the consequences of the company they invested in, there is no incentive to maintain public safety. History has shown what happens...companies repeatedly harm the public with a relatively minor punishment which is less than the money they made off of harming the public, if the company is punished at all.

Corporations are chartered for the betterment of society. If a corporation is harmful to society, anyone involved with those actions should be aggressively removed from society under criminal statute, with even greater fervor then prosecuting a murderer, rapist, or any other criminal who impacts less people than corporate criminals.

man parenting
No manual entry for parenting

We've read a number of books; but our plan has pretty much broken down to

* try and not do what our parents did to annoy us as children

* give them every support and opportunity we can

* Don't let them be assholes
Exactly. I always thought Mastadon could have been so much more successful if they had just proxied cached versions of the most popular instances through a single larger server.

Sure it would give Mastadon the power to pick and choose who it wants to host, but if you want to go join a different instance you are more than welcome to.

It would just substantially streamline the process for your mainstream user.
Ask HN: Compute feasibility of dynamic 3D experiences with the Vision Pro?
From what we've seen, it supports dynamic 2-D content in the form of being able to interact with 2d windows but place them in 3d space.

It supports pre-rendered 3d content such as memories or recordings through special devices - however neither the presentation nor the press release have examples of creating these on the fly or interacting with 3D content.

Given what we know from the presentation:

- that there's a separate real time subsystem running on the R1 chip which actually renders the environment (which presumably developers will not be allowed access to)

- that there is an M2 chip but no dedicated graphics card

- and that in general it is incredibly expensive to dynamically render anything at 2x 5k resolution

apps like static overlays over environments seem feasible to me, but not necessarily the mixed-reality app where (as a paltry example), you play an FPS inside your home or something. Or even something less demanding where you practice as a surgeon in 3d and slice open a realistic body.

Not very familiar with VR - is this a solvable problem with the current generation of hardware we have?
Apple has a full Direct3D 12 emulator for macOS
Lemmy you can host your own server with your own rules, or use a server who's rules you like.
The Index is a neat piece of hardware, but it needed a refresh even before the release of Vision. Now that Apple has planted a flag in the ground, Valve has the opportunity to make a cheaper, open, mixed reality headset, and own modern computing in the 2030s.
not entirely sure what this comment is saying. Night shift workers not as effective? Can someone spell it out for me?
It is a federated piece of software with an instance whose admins clearly didn't realise they were going to get the HN hug of death and an exodus of reddit users today. The application's architecture, as I understand it, is largely horizontally scalable but I'd guess its operations team for the main instance either doesn't have a bottomless pit of money, or hasn't had to deal with user floods of this scale before.

In other words: give them a break.
Shameless plug for a similar project called Collagraph (https://github.com/fork-tongue/collagraph).

From the README: Write your Python interfaces in a declarative manner with plain render functions, component classes or even single-file components using Vue-like syntax, but with Python!

- Reactivity (made possible by leveraging observ)
- Function components
- Class components with local state and life-cycle methods/hooks
- Single-file components with Vue-like syntax (.cgx files)
- Custom renderers

Currently there are two renderers:

PysideRenderer: for rendering PySide6 applications
PygfxRenderer: for rendering 3D graphic scenes with Pygfx

It is possible to create a custom Renderer using the Renderer interface, to render to other UI frameworks, for instance wxPython, or even the browser DOM.

Yes, but to my knowledge it doesn't do any of the complicated optimization stuff that SOTA quantisation methods use. It basically is just doing a bunch of rounding.

There are advantages to simplicity, after all.
Doing so would impugn the free speech and property interests of the server owners.

Why does Reddit have to host speech that it doesn’t want to? Why does anybody? Why is their right to exclude subject to limitations on the government of the United States when they are a private corporation? If the FTC wants to bring that suit, they can try, but that’s a lot to prove and I don’t think they’ll be able to count to 1, let alone 5 if they somehow make their case all the way to SCOTUS.
Police would likely shy away as they are under such scrutiny. Postal employees are limited to $50/yr in tips. With most fire departments being volunteer, occasionally tips or donations rather are offered. These generally would go to the department rather than individual firefighter.

You do if you want to "see for yourself". Which was GPs entire point.
I've had a better time on Mastodon than I ever did on Twitter actually finding people to talk to.
Whoaaaa, myself got permanent suspension on multiple reddit accounts few hours ago. Not related to this topic though. What's happening in reddit?!
It's curious that it only supports immersive-vr and not immersive-ar XRSessions given the focus of the headset. Wonder if it has something to do with their rendering backend, maybe something about camera access or even the features of immersive-ar sessions as well?

Regardless, I'll be interested to see if this starts to promote more interest in developing hand tracking support in upcoming WebXR apps.

I do wonder at such wildly divergent experiences.

It was a fairly small production run, I am reasonably confident, so it seems very odd that some units should be well made with no major flaws, and others apparently awfully shoddy.

Ah well. Sorry you had a bad time. I love mine and am considering buying a 2nd to try Sailfish on, and maybe a spare, too.
The point is that "escape" in this case means not having to work to American Capitalism levels, not escaping working entirely. Retirement in the FIRE sense does not imply in all cases spending every day by the pool doing nothing, and even in the AmCap sense, most who retire and tend to live longer and (self-reportedly) happier, have some work that they are doing, but more along the lines of what even a medieval serf would have enjoyed to the tune of like 15 hours a week.

ETA: often this work is volunteerism, which does not have a capital incentive in the individual case here.
All I remember was seeing some really stale stuff on the front page of Digg, making me look for an alternative.
> It's a long way away for corporate to buy it's developers a headset like what your describing. As far as Work goes, if you cannot get a corporate office to buy them then it's never going to take off.

GDP is driven by consumer spending, business spending, and government spending, in that order. B2B is a nice niche and a person or a company can become wealthy in it, but if you want to be fortune one, the consumer _has_ to be your primary focus.
You're supporting the idea behind "A lot of times, people don’t know what they want until you show it to them." Except, it sounds like the barrier is even higher for some people.
The weights are preprocessed into integer quants combined with scaling factors in various configurations (4, 5, 8-bits and recently more exotic 2, 3 and 6-bit quants). At runtime, we use efficient SIMD implementations to perform the matrix multiplication at integer level, carefully optimizing for both compute and memory bandwidth. Similar strategies are applied when running GPU inference - using custom kernels for fast Matrix x Vector multiplications

The only place I might tip for takeout is a local cafe/diner, which has a tip jar labeled "For the Cooks." It sits at the end of the counter between the cooks and customers. Depending on the cook, I might tip for takeout. (If I dine-in, I might tip the cooks, too; as well as the server.)

Hi Georgi - thanks for all the work, have been following and using since the availability of Llama base layers!

Wasn’t implying it’s CPU only, just that it started as a CPU optimized library.
Maybe I value cross-platform too highly, but I don't see the use of this post... Am I missing something? The claim is that there should be only one way to do it in Python. But then goes on to describe a way that doesn't even work on a major platform.

I've worked on a project recently, a rough prototype, that executes a vast amount of commands via subprocess[1]. I've been very happy with the results of subprocess.popen(). It works well on Linux, Macs, and windows with minimal tweaking.

The funny thing is that the reaction of these platforms when someone advocates for communications elsewhere is to ban those people rather than try to improve their system so that people don't want to leave (reddit is hardly the only platform to act this way). Personally, I'd rather try to build something so excellent that if someone proposes an alternative, most people wouldn't want to leave because I am meeting their needs so well. If the platform is so sclerotic that it can't be meaningfully improved and people are clamoring to leave, there is little they can do prevent an inevitable mass exodus anyway.
Free speech is only protected from government censorship, not private party censorship.

Further, communications platforms are not public forums in the legal sense.

Unless, of course, you're advocating for the government to nationalize Twitter et al. That's a whole 'nother conversation.
Its federated. If you have a problem with that, host an instance.
I think that is why it is both good and bad that Apple have effectively taken the lead in the rollout. They are great at UX and keeping an eye out for edge cases and trying to sand down the worst sorts of gotchas. If anyone can make sure that Passkeys feel good to the average user it is probably Apple.

On the flipside, that early lead also led to so many of the misconceptions about Passkeys that people have. People think it by nature has to be a locked, walled garden, because Apple has the lead and loves walled gardens when it has the lead.

I think that's why this newest rollout announcement is such great news (which we knew was coming, but wasn't obvious to some of those misconceptions from Apple being in the lead): complete integration with the larger ecosystem of password apps already in the App Store wild (use your 1Password passkeys just like you can use 1Password passwords), and a UX for grouping passkeys and sharing those groups with other contacts (that also helps with all the misconceptions about passkeys being some sort of crack down on password sharing).

These UX flows would have been great to have seen in the initial rollout to assuage a lot of fears about Passkeys. It is great to see them happening right now while it is still early enough to stop most of the FUD before it starts to get outside of the HN paranoia bubbles and into average consumer ears.
If you rely on systems that involve implicit custodial trust (i.e. not crypto) to coordinate with your homies, and you have powerful adversaries, your adversaries will compel those custodians to prevent you from communicating with your homies. They also might find you and hurt you.

This happened with thepiratebay and DNS. It happened with wikileaks and paypal. It happened at the ISP level with Signal during recent unrest in Iran. It happens with the US banking system anytime somebody manages to get somebody else on one of the OFAC lists. It happens to would-be radicals on twitter all the time.

On the other hand, systems that don't involve implicit custodial trust don't have these problems, which is why journalists in China occasionally publish on Ethereum, because the Chinese censors don't have a single-point-of-failure to attack.

I don't think that currencies are an especially interesting application (although the wikileaks case is an example where they are relevant to group coordination). It's just that the currencies are what gets hyped because they're relevant to the investment side--without them, there's less money to build the other stuff.

Another example which I expect to emerge, but which I don't think has been developed yet, would be the use of NFT's in a successor system. If the leader of a movement gets apprehended or incapacitated and they don't check in after a certain number of blocks, then a contract moves the leadership token to their successor. This denotes the successor's signing keys as authoritative, and the leader's (presumably compromised) keys as deprecated. If you keep signatures on-chain you can also tell which ones were registered at a time when they were valid.

You couldn't do this on AWS, somebody would just compel AWS to remove the data they don't like, you need something like a blockchain. But it only works if enough people are running nodes to make attacking all of the node operators infeasible. For that you need to provide incentives, and now we're back to cryptocurrency.

For me it comes down to whether you think dissent is more important than preventing all of the shady business that goes on in secret online. I do, so I'm pro-crypto. The currency bit is an ugly necessity which I hope we can find a way to get rid of.
It is a good addition. CoreData, is ok, but is not really used from serous apps. At least, none of the large ones that I have worked on.

The sad fact is not that the author cannot speak about the invention (because of the NDA), but that the patent was carefully written not to disclose anything substantial about the invention.
Tip only on credit cards. Otherwise you foot the bill twice.
That would be a perfectly acceptable comment... 3 comments ago.

Instead, you pretended as if they said AW as an entire category was a failure.

Next time, reply to what is written in the comment, not what is easier to argue against.

Thanks for linking this. I wish the article included actual stats like the scientists expected about 1500 admissions per day, but Sun/Mon had over 1600, while the other days were between 1400 and 1500.
I can't count the number of times that an employee -- usually at a coffee stand -- has clearly been required to point out the tip screen to customers and is incredibly embarrassed about having to do so. They usually lead off with an apology and some disclaimer like "It's totally optional, but..."

This tells me that the tipping has become crazy not because of the employees, but because of the awfulness of the employers.
> it would exclude a raft of non-US citizens then, i.e. any sanctioned country

This lays bare the problem with the status quo. Wanting to profit off sanctions busting isn’t a sympathetic pitch.

Just because something is a "first computing directive", that doesn't mean people do it. If you're capable of remembering hundreds of high-entropy passwords, more power to you, but that approach doesn't work for most people. Password managers are better than reusing passwords between services, which in the real world, is the alternative.
Really? The Sec is 100% infallible deciding crypto is a security but also 100% too-dumb-know when it evaluates a business as fit for public investment?
One, you can design your take home to be LLM resistant

Two, you should always review the project on a call

Three, you don't ask them to do the take home without search or GitHub, do you?

Haha, I knew there was some way of doing this, but I couldn't remember how (tried semicolons which didn't work), thanks :)
> People buy crypto without a real use for crypto because they think they can sell it for more later.

That's not what makes something a security -- many things fit into that template that aren't securities: collectibles, commodities, etc.
do a lot of people even want more social media and internet communities? i wasted an embarrassing amount of time on reddit in hind sight. this all reminds me of when i finally burnt out on wow. i quit, sold my account (at the end of wotlk, i think wow declined after that too?) and didn't play video games for years after. personally i feel the same way about reddit, do i really want this all again in my life? idk, im not searching for an alternative though.

No one in China cares about petty crime in Cincinnati. There may be some long-con, APT style hack of local PDs to try to get into something bigger a la The Cuckoo's Egg, but it's probably easier to just bribe Lockheed managers.

Discord is king if you need information that is only available by word of mouth.

I've found that even trying to search for things I know exist on a Discord server can be very hard to find. One example of this is how statements are split up like text messages. If someone explained something in text over five separate side-by-side posts, then searching for something that appears in two posts but never appears in one will not return the result you want.
That is the policy. The SEC has said that some cryptocurrencies are OK, like Bitcoin and Ethereum. And though today they gave a list of some they don't like, there are plenty of others that they still refuse to talk about despite explicit requests. What is the point of being opaque about it? It's not protecting investors, that's for sure. Seems more like they just want to be punitive.
You can have/ believe anything you like. If you think those things increase their value, and want them to go public, I want them to go public too. I just don't agree/ have the same thesis about their value and where it is derived that you do.

The dam was under Russian control. Ukraine wouldn't have had any opportunity to place demolition charges.

Russia has demonstrated that it is;
- willing to level cities with hundreds of thousands of inhabitants

- willing to use torture, abduction, rape as systematic weapons of war

- willing to indiscriminately attack civilians

- willing to use banned weapons of war

Despite war crimes obviously (d'oh) happening on both sides of the conflict, the Russian leadership has made it evidently clear that is more than happy to unleash any amount of terror, pain, misery and suffering to get what it wants. The Russian leadership is perfectly a-ok to systematically use all of the aforementioned as weapons.

I've not seen this callousness from the Ukrainian leadership.
