Whenever I hear of exotic comms stuff like this, I think about command and control use cases. Quantum computing is about security of the cryptographic security infrastructure (PKI, TLS, etc). New physical layers are all about diversification. It's less about disruption and more about security.
It seems like maybe they didn’t pay in enough - baby boom demographics meant there were relatively more productive workers paying for relatively few old people, so each worker was paying a fraction of what it would cost to carry themselves through old age.

Also, not enough kids, and of those, not enough who wanted to go into medicine.

It seems like baby booms have a way of making things seem artificially good for a while, and then there’s a hangover.
Something like 10-50 of the population worldwide, depending on where/how you measure, moved from rural areas to cities since WW2. This completely upended the large scale population density situation that had existed for millennia. Also, as I'm sure anyone in California or Texas will tell you, there are 1) only so many good places to build and/or 2) so far someone is willing to commute. There is lots of land available to build on 4 hours from San Francisco at pretty reasonable prices (I looked at a 2.5 acre triangle of land with a seasonal creek on it for $40,000), but nobody will pay $900/sq ft for a house that far from their office, even if they WFH 4 days a week.
Seems mostly reasonable, except for consistently translating SIBEN to fünf (five) rather than sieben (seven).
They dind't lie, just kept silent of all uncomfortable truths, it soured my image of the RH the way they handled this
This reminds me about a couple of famous fics that each have their own fics inspired by them: Harry Potter and the Methods of Rationality [0], and The Arithmancer [1].

The first has it own wikipedia page and its from the creator of LessWrong. From Wikipedia:
> It adapts the story of Harry Potter to explain complex concepts in cognitive science, philosophy, and the scientific method.

I read it almost 10 years ago but remember it getting tiresome after a while, but it does teach a ton about logical thinking.

The second is a less famous fic where someone who must have at least a masters in mathematics wrote Hermione as using math to create her own spells, theories and gradually becoming better at magic as she turned into a better arithmancer, and everything is based in real world theory.

Show HN: Platform for building Gen-AI applications on Spark
Hey HN, I'm Maciej, one of the co-founders of Prophecy (https://prophecy.io) - low code for Data Transformations and Generative-AI.

We've just released the latest version of our product, which makes it easier for teams to build data pipelines for LLM-based applications. As part of the release, we're also open-sourcing the toolbox for Spark (https://github.com/prophecy-io/spark-ai) that contains useful connectors, transformations, and agents for building Gen-AI applications.

Hopefully, this allows some of you to build your apps easier and make them more robust and scalable from day one. Quick getting started example available here: https://github.com/prophecy-samples/gen-ai-chatbot-template (all code is open-source too).

While our product is already mature, the toolbox shared above is still in a pretty early stage but will be completely OSS. Any thoughts on the concept and ideas for what's important to the community would be super appreciated!
I had never heard this term before so thanks for sharing!
yup, no real way to avoid it though
This is what my parents did. They always said they’d be happy if I decided to become a poet if I wanted as long as I committed myself to it and didn’t just use it as an excuse to lay about all day. I always thought it worked out well.

Baseball is also a beautiful sport that combines the fun of playing a game with cutting edge tech and analytics. It can teach a curious child that keeps asking “why?” a lot while still being fun (unless you’re a Mets fan), and it’s a sport that you can keep playing basically your whole life in rec leagues at all sorts of skill levels. Even if she doesn’t end up with a career in the sport, there’s a lot her passion for the game can teach her.
Would you have any good primer on materials science to point me towards? I find this fascinating!

iOS allows setting Location Services per app which is pretty good IMO.
> HFT changes these "beliefs in company" to "beliefs that the stock will go up", and the timeframe of those "beliefs" is sometimes in milliseconds.

None of this prevents you from investing using whatever long-term paradigm you prefer. The effects of HFT on that investment style are negligible.
> Signal vs noise ratio is too high.

This isn’t saying anything other than your not a fan. Which as I said is fine.

> My point is that the model of Blocklist from others is not enticing for any individualistisc user who values diversification of ideas and the fact that the default makes it a bad burden for the user who wants to try that, means that communities won't be formed that don't have that blocklist mindset, one way or another. The model is too focused on closing down networks instead of invidual choice. Utility, since it's not like the internet where traffic is good, seems to be around creating extremely narrow minded pools with little crossover, since any exposure to widened thought can be immediately shut down.

This was unspecific/vague and not an accurate description of the fediverse. It’s a very diverse (unfortunately so in some cases) group of communities that interact with each other. Or don’t if they choose.

The value in allowing each instance to handle their own block list is that it scales and allows you to choose a server that shares your perspective. And basically if you disagree that this is the case, you’re free to change that and that’s the point. You have all of the choice.
Sure, spheres acting as a pressure vessel make 100% sense.

Even conceding they may be the only sensible choice for that environment - they are still not space efficient.
The conversation is about pedestrians walking into traffic while staring in their phones, jaywalking in other words. Please don't try to ad hominem, it just shows that you don't have any arguments of substance and degrades the discussion.
Samsung devices appear to use the camera and/or the proximity sensor to display a "Your phone appears to be in a dark place, slide to unlock".

Unfortunately it seems easy to unlock that as well.

The biggest problems I have with this are related to the "raise to wake" and "tap to wake" features that seem to be enabled by default on all the phones I've tried including iOS devices. I think on Pixel it was called "pick up to check phone" or something else like that. Turning these off drastically reduces the number of times the phone turns on in my pocket because the power button becomes the only way to activate the screen.

On Samsung phones you additionally have to turn off a setting under Always-On display so that widgets are turned off and/or cannot receive touches, such as the music app etc.
We do have a useful invention called the screw. With every phone phablet sized nowadays there isn't a valid argument that they don't have room for waterproofed fasteners.
I'd tend to say that the author's stated intentions matter more than whatever headcanons you or I might come up with, but not as much as the work itself. After all, unpublished intentions like that can always be changed later if the author has cause to publish something that would contradict them.

The author can (generally) be considered more correct than us about the details of their story, and what background elements exist that informed events but which weren't shown directly in-story.

This certainly doesn't mean that people writing fanfic, or just enjoying the work, can't go wild and change these things. I just feel it's worth knowing where you're departing from "official canon", rather than claiming that you must be right.
So the lesson learned here that very wealthy people are more interested in not paying taxes than they are in owning their own planes and yachts?

I understand that $2.2 million is more than $2 million, but I find it kind of baffling that people spending that kind of money on that kind of thing are price sensitive.
Lasercom has been demonstrated well on Earth but it still is a very nascent technology in the space domain. There are several challenges that lasercom faces.

First, in order to enable global communication you need a constellation and good constellation management. This requires fewer spacecraft if you are in GEO, but GEO spacecraft tend to be larger and more expensive.

Second, lasers draw a lot of power. Most is waste heat as far as the spacecraft is concerned, but this can become a problem if the duty cycle is high. High power means much larger arrays, and for a LEO constellation, serious eclipse challenges.

Finally and most importantly, pointing is a challenge. Maintaining pointing control in space is hard, and lasers require much greater accuracy as compared to RF. With RF, the lobes are relatively large and allow some play when it comes to downlink to ground. Lasers are unforgiving.

I’ve led several spacecraft missions with lasercom terminals, and every time it has made development markedly more challenging. I think it will be quite a while before it is mainstream, and certainly before it replaces fiber.
You're right. A University of Michigan study predicted 12 years ago that cars would be bigger to "comply" with CAFE fuel standards.

> The strength of floating point is that it bounds % error rather than absolute error. Similar to how scientific notation has a % error represented in the form of number of significant figures.

Not just similar, precisely the same: scientific notation with a fixed number of significant figures is pencil-and-paper decimal floats.

Having mentioned decimal floats, though, I have to note that they have worse precision bounds because the pieces in the piecewise approximation are larger.

For example, with four binary digits, one unit of last place expressed as a relative error lies from binary 0.001 / 1.111 to binary 0.001 / 1.001, that is to say from about 2^-4 to about 2^-3, a factor of two, whereas with four decimal digits it will be from 0.001 / 9.999 to 0.001 / 1.001, or about 10^-4 to about 10^-3, a factor of ten. The usual phrasing is that the wobble of the number system is smaller with a smaller radix.

Trading more wobble for less digits is reasonable when calculating by hand, but makes no sense on a computer. Even on paper some books will tell you to refrain from rounding down to ...1 when a value ends in ...11, ...12, or ...13 in order to avoid the worst of the wobble.
> Get labor levels back and get labor levels back at below market rate are different.

Businesses complaining about labor levels because they're too cheap to pay labor market rate and businesses complaining about laws which require them to hire employees at rates which the market will not bear are different. It is pretty clear the person I responded to thought the rate which would bring labor levels back up is not something which would be tolerated by the customers.

>>> Let labor prices keep going up, and soon no gas station attendants will be required because voters will want cheaper gas prices more than they want someone to fill their gas.

> yet companies that complain about labor levels are basically outing themselves as bad employers

Are they really bad employers when they are complaining about laws/regulation which require them to hire people for positions their customers won't pay for and do not need? I would imagine most gas stations would prefer to become completely self-serve. I don't see gas stations any place which does not require an employee to pump trying to hire people in any significant capacity to pump gas. I don't believe I've ever seen one. I don't see voters in Oregon tolerating the requirement for much longer if the market rate is above what they are willing to pay. Pushing to change laws to conform to a new reality is not a sign of "bad employers".
> one thing

There are also guillotines. It never ceases to amaze me that pro gun rights people are generally anti union. Both are extra judicial exercises of power to get a seat at the negotiating table and ultimately prevent tyranny against ones self. Both involve seeking justice through use of force when justice is no where to be found.

> And they don't want consequences against the aristocracy because they have this delusional notion that one day they'll be a part of said aristocracy.

This is over simplified and echo chamber talk. This would not survive a conversation with a skeptic. Those people wouldn't say that they are anti-union because they might eventually be a business owner. They would say that one of the authorities they trust said unions are corrupt and won't work, ignoring the business owners corruption who paid for that authority to sell that story. Conservationism frequently lies with the truth. Only through understanding the bigger picture can you understand that the framing of a given truth creates a lie in the context of a bigger picture.

They have been lied to about cause and effect by entities like fox news and don't have the critical thinking skills to question it. People who believe in trickle down economics don't believe it because they think they will be able to trickle down onto others in the future, they believe it because someone they held in a position of authority told them it's an optimal economic system and they didn't think about it too much or question it.

If you build a culture around following authority and not questioning it too much (like church) then it's easy to hoodwink those people because they are used to trusting [their] authorities without question.
> I'll choose the model "Enigma M3" and use the following settings:

Well it's obviously not that.

The M3 was the 1934 design. In 1942, the German Navy replaced the M3 with the M4, which was incompatible with the M3. This message was sent in May 1945, just days before the end of the war.

Ask HN: How to secure personal web apps?
Let’s say I have a web app that runs in the browser and can be served over HTTP from a VPS.

What’s the easiest way to secure that app so that only I can access it from my computer and phone, even when away from home?

This sounds like a use case for a VPN, but how does that work in practice, with minimal hassle? Would WireGuard work in the case I want to access the web app over the internet, with my phone’s browser (without any extensions, ideally)? Are phone VPNs smart enough to only send traffic through the VPN for certain domains?

I’m sure there’s a guide written about this topic somewhere, but I’ve spent quite a bit of time searching and everything I’ve found either doesn’t mention phones, doesn’t mention web apps, or assumes you want all your traffic routes through the VPN (or is incomprehensible SEO nonsense).

Edit: I didn’t discuss serving the site over HTTPS and having an actual login flow because that seems like it would be annoying to setup, but feel free to convince me I’m wrong!
That's a good point but typically larger customers already have infrastructure they can put this on, as it's fairly low overhead, works across OSes (with a bit of config in some cases), and doesn't require anything specialized. It can be added to their existing cloud or baremetal at minimum marginal cost.

Strictly speaking, even if you were to go with a public cloud provider, and set up new infra specifically for BrowserBox Pro, you can essentially get an infra cost/seat/month of < USD1 anyway--making it still cheaper than Cloudflare, at least at scale above 100 seats.
If not for the physical space constraints (crowded streets) - I suppose I do. More folks around means more opportunities, more diversity. Even if I won't interact with 99.9% of them, why would I be against a possibility that they'll bring something more I might like to the table? I mean, unlike in physical world, no one can shove anything up my face unless I'm specifically in a mood to see what else is out there.

The beauty of distributed digital landscapes (as opposed to corporate-ran walled gardens) is that you're in more control of how it works and what you see. When there's no central hub, there is no land to fight for - I don't have to see the giant concrete anthills of dense cities, the space I see is configured to my preferences. And of course I would like to have more options of what to read and whom to talk to, than less. Even though I'm unlikely to consume any of this Instagram content (it's just not my thing).

So, I don't quite get this "barbarians at the gate!" thing. But then I don't get the idea of Fediverse servers as some sort of communities either - to me having a shared server is just an unfortunate consequence of technical limitations making it's highly impractical a true distributed system. I really don't want to care what server something or someone is on.
Personally I think the SD1.5 trade off, loss of general knowledge for surprisingly high quality images on consumer hardware, is worth it.

It's fairly impressive to me what the community has made possible with SD1.5. Sure on a vanilla task something like Dall-E 2 generally performs better, but with some tweaking you can easily beat out Dall-E on a home gaming PC.

The fact that you can fine-tune SD1.5 on a 4090 is incredible to me.

Given how much powerful AI is locked behind fees and private APIs it's refreshing to see so much cool stuff coming out of the OSS world again. Best of all is it's not being driven exclusively by people with an ML background, but moreso curious amateurs. It really brings me back to a time when playing around with software/the web felt exciting.

Well, you answered yourself why it went as it did. Don't you think answering to your shareholders is what keeps the company competitive and on the right course?
> Instead of trading on the merit of a given company, it simply reinforces the market

What you're proposing is actually not a ban on HFT, it's a ban on investment strategies other than value investing. How would you implement that in practice? Have every investor swear under oath that they do believe in the company's inherent value, regardless of the rest of the market's behavior?

> HFT goes against the original ethos of a market open to all.

What "original ethos" is that? And even if it existed, wouldn't excluding certain investors go against it much more?
Indeed, as I’ve learned this is a western perspective!

Old Alan Watts lectures cover this nicely, and can be listened to for free on YouTube and elsewhere.
> beat humans at a 5k race also isn't very interesting (at this point), because fine, you created a running robot, but that robot's not going to do it's own taxes at the end of the year, so in the sense of AI, who cares.

It depends exactly on what we're saying. So far we have machines that can navigate language well, but aren't good at navigating real world environments. If we're talking about a road 5k race, with myriad ways that courses are marked and many, many distracting, this is at least an interesting problem (perhaps as difficult as self driving vehicles).
My family rented an Earthship for a long weekend in Taos. It was kinda cool. Pretty nice house, but they're very expensive to build.
"It depends." poetry2nix is pretty good! Generally, exporting to an OCI image, or targeting a production environment that can run Nix closures natively is the way we go about it. Many of our services use buildLayeredImage[0] and target Fly.io.

Interesting, fibre optic cables can be tapped by an adversary, it's difficult to physically secure the entire length of the cable.

Satellite radio communications can be monitored, as the signal is cast over a wide area.

Satellite laser communications however, would be much more difficult to tap into.

Hey OP here - I mostly agree with your points in respect to AMap. It's a legitimate mapping service and location SDK.

> Why not mention it's AMap in the tl;dr summary?

The GPS data is being sent to two different companies - the battery monitor developer and AMap. I could make this clearer in the tl;dr.

The cell phone tower data (MNC,MCC,LAC,Cell ID) and Wifi BSSID collection is AMap only.

That said, none of the AMap behavior is disclosed by the application developer. Literally apps that use the AMap SDK in this way turns the user's handset into a continuous scanner. This impacts user experience - just check all the complaints on the 1.75k reviews on the Play store [1].

I doubt many devs are aware of this - It took me countless hours to figure the AMap side of things due to obfuscation techniques in the AMAp code. (See part 2 on the blog post series).

The primary issue is that all this data is collected, sent to multiple 3rd parties (AMap being one of them) and none of this was disclosed to consumers when they download the applications.

Why would you lie on something so easily verified?
I wouldn’t mind seeing the network requests made and received by apps.

For noobs it could show the domain, and if it’s whitelisted by apple somehow it is green (server certs?). Yellow if it’s not whitelisted and not on a banlist. Or maybe skip the colors if it’s too confusing for people, annd just show the names. Apps that request to banlist are blocked from App Store until further review.

and for pros we can tap to see more details, like the payloads and headers. Etc.

What do you think? I really want this feature. It’s not that hard to add. Come on apple.

Wish I worked at apple then I would try and do it. Lol.
> you have to take the viewpoint that Richard III is a character, a cultural product in the same sense that Captain Kirk is a cultural product

The piece seems to be arguing that Richard III's motives, and specifically the circumstances around why he became king, are somewhat uncertain. As such, it feels that the popular historical narrative around what happened (treachery! usurpation!) is a cultural product without too much concrete evidence supporting it.

This feels reasonable to me. "We know facts X and Y", is true. "As such, Z is what we think explains X and Y" can be convincing, but is also inherently speculation.
40,000 divided by 1,000 is 40, right. Or 3.33/seat/month. 40K is yearly, not monthly if that's where you got a bit confused.
