I’d say the odds of this being nonsense is at least five nines. :)

If not, what’s to prevent the simulated sentients from developing sufficient simulated technology to simulate their own sentient simulations? The rate of technological advance in the base reality would have to keep pace with the accumulated capacity demands of all nested simulated realities.

Compute is not infinite, and sentience is not static. The premise is unsupported

> so they still have to harden it against this hack

True, but LIDAR should make that detection more robust.

For example, if a stop sign is on the same plane as the object that surrounds it, that's a strong signal that it is not a real stop sign but rather a projected or displayed one.

That's much harder to detect with computer vision alone, especially if they're dealing with hackers who can test it with a real car and continually iterate on it to find different ways to trick it.
So one thing is was thinking about. The other day we saw a paper about room-temperature super conduction right? That field has a seen a long gradual progress.

But cold fusion "field" seems to be trying to go from nothing to everything in one step? Is there anyone who has been successful lowering the temperature required by even a single degree Celsius? And to make it even easier, let's include fusion that does not produce net energy.
>I'm pessimistic in this case because I sense a culture shift. Few media, few intellectuals, and few politicians initially condemned the rioting or looting or violence.

I appreciate your point of view and anyone who didn't condemn violence should be roundly criticized.

However, my experience here in NYC was much different.

Not only did pretty much everyone decry the violence (a significant portion of which -- and there's plenty of video evidence too -- was instigated by police), but time and again over the two or three days that there was looting, the protestors took it upon themselves to stop the looters, because no one wanted that -- except the looters.

What's more, much (not all) of the violent actions against police property were perpetrated by folks from out of town.

I can't speak to Portland or Seattle or Kenosha, but here in NYC, even some of the police[0][1] stood (and knelt) with the protestors to condemn police violence and urged the protestors (to cheers, I might add) to kick the looters and other violent folks out.

There's nuance there and it's sad (especially in the context of discussing social media) that those nuances are lost in social media bubbles where the loudest and most extreme are given undue exposure, if not primacy in the discussion.

In traditional Christian thought, they were priests in both the universal Christian sense and in the sense of the ordained office, since that office is fully contained within the office of bishop, which is fully contained within the unique and only partially (exactly as far as the office of bishop) transferrable office conferred upon each of the Apostles by Christ.
Maybe it's more like, "I'm good at this one thing, but these are some tools I find useful to achieve that."
This is a common misperception. You cannot estimate the shape of simple things in low light. Even humans are susceptible to optical illusions and are effectively blind during certain times of day (try driving in the direction of the sun during sun rise/set). Lidar is not susceptible to any of these things.
Similarly ML will never solve low light or direct light situations, that is a physical limitation of cameras.

Isn't there really bad lag inherent in that process though? (My only source is personal experience with a HDMI-to-USB3 capture device with ~200ms+ lag - about 6-7 years ago)

If you want a good quality camera for Zoom/Facetime/etc anything over ~32ms would be grating - especially if you're using an external microphone attached directly to the computer.

I actually do think it matters. I also think there should be a distinction between things leaked by a whistleblower and things leaked by a thief or a patsy. However, since whistleblowers are often putting themselves at significant risk, we end up relying on the integrity of the journalists / publications in terms of taking their word for the legitimacy of the source.

So yeah. A publication that makes a significant effort to vet their source and the story deserves the benefit of the doubt while a publication that acts as a click-bait tabloid without any kind of investigative effort doesn't.

That said, I think Twitter is grasping a bit and trying to use a policy that's right or wrong when the reality is more subjective.

The other thing I don't understand is how revisiting section 230 of the DMCA and turning Twitter into a publisher is going to improve things. If the current publishers don't suffer any repercussions for anything, how will it be different if Twitter is considered the publisher? They're looking for a whipping boy IMO.
They have quite a few videos where they make things. Their videos get recommended to me alongside videos from machinists and fabricators.

The efficiency loss compressed air suffers is mostly at the hands of the ideal gas law. Storing energy by pressurizing the container heats up the gas which increases the pressure requiring even more energy to store additional gas. When retrieving energy it depressurizes the container which cools the gas down which reduces the pressure which gives you even less energy. What if they could cancel out?

Say you have two separate pressure vessels where to charge the system you pump air out of one into the other. Well the depressurizing vessel will cool down, but the pressurizing vessel will heat up. If they came to thermal equilibrium with each other their net temperature change would cancel out somewhat. This is great because it would restore the pressure on both sides to have more favorable conditions for energy storage and extraction.

So I wonder if you could design a pressure battery that would exhibit no change in temperature on the exterior throughout the charge/discharge cycle.
SaaS teardown for efficient feature development
Hi HN!

While building SaaS products, I always end up wishing that there was a product or service that could provide me with a teardown analysis of specific feature areas from popular SaaS products out there.

For example, if I'm building a "Team" feature, I want to know how have other products have implemented it. How does the workflow look like? UI? UX?

There are probably thousands of other products that have built and implemented the same feature, so seems kind of inefficient that I have to reinvent the wheel every time.

Do you know if there is an existing product or service that already does that?

If not, and I built it - would you pay for it? How much per month?

Yeah, I don’t get it either. Unless the point is that you should completely discard the food, rather than trying to remove the moldy bit and eat the rest?

People never died for no reason, though, they just didn’t understand the reason at the time. The implication is that they thought they had removed the mold and they hadn’t and so they died?

Interesting site. Bookmarked. But the last part "Communication: SPI, I2C, CAN-bus, ethernet should be sufficient. A ZigBee like protocol would also be highly useful." made me think why?

Especially Ethernet. When you are bootstrapping, why emulate what became standard for arbitrary reasons which don't necessarily apply for the situation requiring a reboot?

Maybe something like https://en.wikipedia.org/wiki/ARCNET would be simpler to implement, while covering much of the needed/wanted functionality?

Otherwise thumbs up for going along with CollapseOS and FORTH :)

My issue here is this is not really a honest conversation most of the time.

Wanting to work from home generally means just that, wanting to work from home. Not wanting to work from home however usually really means "I don't want others to be able to work from home", it's about taking options away from other people. The exception being people who don't want to work from home because they have a pack of screaming children at home, etc - in their case saying they don't want to work from home is actually honest.

Your comment is a good example. For your perceived issues to be resolved, we need to make other people work at the office. The idea that others shouldn't have the option to work from home because them being at the office helps someone else build their network is not something I can agree with.
Do you think it should be illegal for HN to moderate posts and ban users (without accepting legal liability for all user generated comments)? If HN can moderate comments, why not Twitter? If you think it's unethical for HN to operate the way it currently does, why are you still here? Maybe you should stick to your principles and delete your account.
Having converted a few things to wasm, I think porting SuperCollider would be considerably more difficult than modulating a bunch of WebAudio oscillator nodes together. Especially since SC is architected as multiple processes communicating with each other. That said, it's not totally crazy either, but it would be a wholly different kind of project.
I don't think there is too much information. There are plenty of very busy people with very good grasps on the world. I think it's more that people don't give time to information, and prefer entertainment. People in the U.S. spend on average 4 hours a day watching TV, not reading newspapers.
There are popular cars in the US that use two cameras for their self-driving functionality. Kinda like humans.

Reminds me of a strawberry about 10 years ago. Beautiful, big, red, unmarred strawberry. I take a bite out of it, and as I pull it away from my mouth I see that the entire inside is filled with the remaining half of a living worm, along with a great deal of what I assume were its excretions. I see this just as the taste hits me.

My wife heard the noise I made from across the house and assumed I was being histrionic, but she changed her mind once she saw the remains of the strawberry! In fact I think she came closer to vomiting than I did—fortunately I was right in front of the sink, so was able to spit it out and wash out my mouth immediately... It was years before I ate another strawberry without first cutting it in half.

>Until that actual public square exists online, Twitter, while they may have the legal right to silence you, have an ethical responsibility not to - because THEY chose to provide the platform that they knew everyone would use.

You are under the misapprehension that Twitter (or Facebook or Google, or any corporation for that matter) has any ethics at all. They exist to make profit. And anything that doesn't align with that is unimportant to them.

I'd also point out that on Twitter or Facebook, you aren't the customer, you're the product. And they keep you in your little section of the feedlot (filter bubble) to keep you pacified and feeling good, as they profit off your PII and eyeballs.
They tried to promote the launch of this service on a bunch of linux-related subreddits 6 months ago, and I wasn't much of a fan of the concept or the way they advertised it, in skipping over the p2p nature of the system.

Their answer to the question of 'what happens when a bad actor has their illegal activity routed through my connection' seemed illogical. They claimed that as more people signed up, the proportion of bad actors would decrease [0], which makes no sense to me.

Also, I'm not entirely sure what methods they have taken to stop a bad actor from collecting packets from other users that are routed through the bad actors exit node.

The worst thing IMO is the way it's being presented and marketed. The impression the website gives is that its just like all other VPNs but free, which is very misleading.

The only practical way for the Post to verify the authenticity of the emails is via the DKIM signature. It's also trivial for them to share the emails and their headers as opposed to just sharing screenshots of them, if they're interested in making it easy to verify the emails' authenticity.

> Since the alternative is leading us toward actual violent war, I say “make HN choose between moderation and immunity too, if we must” without hesitation.

Just the opposite. Companies unwillingness to intervene did so. Your opinion may be different, but it's nothing more, and suggesting we deny people their civil liberties based on your hunch is a dangerous line of thinking.
True, but there is a big difference in operating an exit node and using a VPN. Millions have VPNs installed. These is only a small amount of exit notes, and millions use VPN.

I'd argue that the chance of being accused because someone used your connection in p2p VPN is less than when someone will use your wifi to do something illegal.
It looks like this will help protect your privacy when configured properly, however, it may be more difficult to accomplish one of the key values VPN users seek: navigating around censorship walls. Does anyone know if it's possible to specify the location of your exit node in the network?

How are you going to convict Russian intelligence officers? You think Russia will hand them over?

Again the hard evidence that you are dying to see is classified and would reveal American hacking capabilities. If Putin is not willing to send over his officers who did that hacking, then why should the US government give up the evidence for nothing in return?

Revealing how America identified the Russian hackers would be extremely valuable for Putin and his KGB/GRU operatives. They can use this information to better their hacking operations in the future.

She wasn't looking at the road because she was entering data about the drive into the uber app, at uber's request.

Also, even if she wasn't doing it at uber's request, this is such a predictable event. The driver was paid close to minimum wage... Regardless of how you feel about this, it's definitely the case that people who are paid minimum wage will typically give minimum effort. This was totally forseeable. The people in charge of making this decision at uber were either negligent or willfully ignorant, but there's no excuse to hire someone for near-minimum wage for this job if you truly care about safety.
