I wonder what kinds of techniques, if any, these virtual cell phones employ to evade being discovered. You would suspect that they could be discovered through triangulation.

Two possibilities:

1. Most if not all of these virtual cell phones are connecting from the same location.

2. Some of these virtual cell phones are connecting from the same location, with the remainder in reserve.

In the case of (1), you have both a fixed location and a high saturation that is unlikely.

In the case of (2), you could imagine using certain numbers at certain times to simulate the work day or hours during which people are more likely to be at home. Randomization or round robin could produce unlikely patterns, but without them, these virtual phones would be underutilized, save for some kind of cyberattack that would compromise their location.

Or the truth simply may be that they aren't doing anything, because no one is watching.

The article doesn't make this clear... is sharing a house illegal, or is it only illegal to separate leases for each room?

Immediately post-college, I shared houses with other 20-somethings. It was always a single lease - 4 roommates listed, 4 beds, all of us responsible for the full amount of the rent. But, we were absolutely allowed to reside in the same home. Same thing in college - single lease for four people in a four bedroom apartment.

Edit - post college was Northern VA (DC Metro). College was UVA, Charlottesville, VA.

Edit 2 - partially answering my own question... For Fairfax Co, VA... Can a home or dwelling unit have multiple renters? Generally, no more than one family, plus two renters, may live together as a single household. Or, no more than four unrelated people may live in one house as a single household. https://www.fairfaxcounty.gov/code/multiple-occupancymultipl...

All my past rentals were 4 people, so within the limit. And given the size of most homes (4 bedroom is typical), doesn't seem totally unreasonable (ADUs and "granny flats" count as separate homes, so not covered by the 4 person rule).

I sure wish SpaceX would just open source their designs so that nations around the world can join the space race, we can truly evolve as a whole species and not just as national identities, and we can get on with mining Psyche 16.

That would be a truly revolutionary human endeavour, imho.

Meanwhile, we're lobbing rockets at each other to kill innocents at massive scale, when we could, as an entire species, be building literal cities in the sky.

Nevertheless if Europe starts making progress, I'm sure it'll catch up with the USA and China. Some day. Assuming we don't nuke ourselves over idiocy first.

I know, it's a pipe dream. But a person can dream for the stars in spite of all the hatred that says otherwise.

> Because Europe offers clean safe cities and good WLB

So does Australia and New Zealand.

And you are much closer to family as a result and in a countries where Asians are well represented and with the added bonus that they are Anglophone countries so no need to learn German, French, or some other European language that isn't English.

Look, Germany is a good country, but it legitimately isn't enticing for the kind of Indian or Chinese national who came to the US on a work visa.

> If all you want is to be in a big Indian diaspora and make a lot of money then I guess California is a good fit for you. Glad you like it

That's what most diasporas want. Look at the statistics of where the Indian, Chinese, and Korean diaspora are clustered. Amongst western countries it's overwhelmingly North America, Australia, and the UK

> then I guess California is a good fit for you

It is. I've been here since I was 1 years old when my parents were part of the initial work visa expansion in the 90s which brought tens of thousands of us Indian, Chinese, and Korean Americans to the US.

If I were to leave, I'd probably go to Singapore because I can take advantage of Asian dealflow while remaining in an Anglophone country where we are overrepresented.

It’s not that difficult to become a billionaire. If you can collect $1 dollar from a billion people, you’ll be a billionaire. If you increase that to $10, you only need 100 million people, roughly a third of the United States.

What you need is some kind of platform on which you could collect those dollars. In recent history the internet has become a powerful platform and that is why we have so many more billionaires.

But what has not changed is our sensitivity to good deeds. If you’re a billionaire, giving all your wealth away is not really going to be appreciated much more than doing some highly visible good deeds that give smaller amounts of wealth away. So why do it? There is diminishing returns for good deeds. You’re better off staying a billionaire until you die, after which your wealth will be distributed anyway.

This reminds me of places where it's illegal for more than N~=3 women to share a residence, ostensibly to prevent sex work (the assumption being that any home with a significant number of unmarried women is a brothel).

When I was in high school a couple decades ago visiting liberal arts colleges across the Midwest, it was a common refrain that only fraternities had houses while sororities did not because they would be illegal (at least, historically).

This is neat, and I click the little upvote because hyper-optimizations are a delight.

But realistically, is there any real-world situation where one would use this? What niche or industry or need would benefit from this, where the dependency + setup costs are worth it. Strings just seem to be a long-solved non-issue.

You certainly don't want yucky undesirables to have shelter when homeless, to be fed when hungry, to be clothed when naked? Just because they happen to be the same species as you? Just because their blood is the same color as yours? Just because that's the moral teaching of every dominant religious system? No, some people should be homeless, and suffer, and be made to bear humiliation. It is self evident that the suffering of the marginalized is a social good which the people must not be deprived of.

> but I don't we've solved the map problem.

Agreed! If we use `map` directly, Cap'n Web is still constrained by the ORM.

The solution would be what you're getting at -- something that directly composes the query builder primitives. In Typegres, that would look like this:

``` let friendsWithPhotos = friendsPromise.select((f) => ({...f, photo: f.photo()}) // `photo()` is a scalar subquery -- it could also be a join ```

i.e., use promise pipelining to build up the query on the server.

The idea is that Cap'n Web would allow you to pipeline the Typegres query builder operations. Note this should be possible in other fluent-based query builders (e.g., Kysely/Drizzle). But where Typegres really synergizes with Cap'n Web is that everything is already expressed as methods on classes, so the architecture is capability-ready.

P.S. Thanks for your generous offer to help! My contact info is in my HN profile. Would love to connect.

The debugging experience and the lack of context shift when going from thinking about how C# works to JavaScript (and all its zillion quirks!) is insanely better. I can put a breakpoint for the front-end and debug it just fine withing VS. I do wish Microsoft would finally open source their debugger, since I've heard loads of complaints about it being proprietary still.

We developed a free Mac binary to help address many of the common concerns associated with MCP servers. Happy to receive feedback! A lot of the risks for MCP are not necessarily new - you could say they simply exacerbate existing risks. We tried to address some of those - the most AI-ey feature is the AI as a judge feature that does a pulse check on input and output to an MCP server. The other features are typical, whitelisting tool calls, protecting secrets, etc.

> If AI stays on the trajectory that we think it will, then amazing things will be possible. Maybe with 10 gigawatts of compute, AI can figure out how to cure cancer.

At least the statement starts with a conditional, even if it is a silly one.

If you know your growth curve is ultimately going to be a sigmoid, fitting a model with only data points before the inflection point is underdetermined.

> If AI stays on the trajectory that we think it will

Is a statement that no amount of prior evidence can support.

I remember before Rust when Go vs. D was the topic of the day. I even bought a D book and was working through it when Go was announced, and it won me over. The difference maker for me was the standard library; working with Go was just easier, full stop. That and using names like 'int64' instead of 'double', because that's what my brain likes apparently.

Many prominent Stoics advocated the use of “negative visualizations” for a number of reasons. One argument for using negative visualizations was that by imagining potential misfortunes, one could prevent and avert them. Another argument was that they believed misfortune strikes hardest those who believe life is a bed of roses:

> “But no matter how hard we try to prevent bad things from happening to us, some will happen anyway. Seneca therefore points to a second reason for contemplating the bad things that can happen to us. If we think about these things, we will lessen their impact on us when, despite our efforts at prevention, they happen: “He robs present ills of their power who has perceived their coming beforehand.” Misfortune weighs most heavily, he says, on those who “expect nothing but good fortune.” Epictetus echoes this advice: We should keep in mind that “all things everywhere are perishable.” If we fail to recognize this and instead go around assuming that we will always be able to enjoy the things we value, we will likely find ourselves subject to considerable distress when the things we value are taken from us.”

A third argument put forward by the Stoics is that the use of negative visualizations makes you realize what is truly valuable to you and appreciate it:

> They recommended that we spend time imagining that we have lost the things we value—that our wife has left us, our car was stolen, or we lost our job. Doing this, the Stoics thought, will make us value our wife, our car, and our job more than we otherwise would. This technique—let us refer to it as negative visualization—was employed by the Stoics at least as far back as Chrysippus. It is, I think, the single most valuable technique in the Stoics’ psychological tool kit.

And a fourth argument is the one you highlight, that thinking about death makes us realize how precious life is:

> Why, then, do the Stoics want us to contemplate our own death? Because doing so can dramatically enhance our enjoyment of life.”

(All quotations are from the book “A Guide to the Good Life: The Ancient Art of Stoic Joy – William B. Irvine”, which comes highly recommended.)

Look for a broad-strokes summary of environmental laws in China [0]. Note the following paragraph:

> The standards detailed in the action plan focus on several harmful substances, including particulate matter (PM2.5 and PM10), sulfur dioxide (SO2), nitrogen oxides (NOx), and volatile organic compounds (VOCs). Each of these pollutants has defined permissible levels, which are critical in guiding both regulatory authorities and industries in their compliance efforts. Over the years, the Chinese government has intensified its efforts to monitor real-time air quality and ensure adherence to these standards

Now try to reconcile this with the actual air quality [1] [2]. Note that September is far from the peak, when it gets cold and dark the air quality in many megacities becomes off-the-charts toxic.

This leaves two possibilities: either the state is too weak or too corrupt to enforce these laws. Since the PRC is far from weak and its organs are very powerful, this only leaves one possibility.

The study is about VOCs. You’ll want a carbon filter, as even a HEPA filter won’t do much.

Also, don’t put a HEPA filler in your HVAC return — not only is it unhelpful overkill, it will have excessive static pressure drop, thus wasting power, increasing noise, reducing airflow, and potentially damaging the blower. Use an appropriate filter in the MERV 13-16 range.

I'm a scientist and a scholar, and I am right now living in a HMO with some lovely/interesting/weird housemates while I sort out my horrific divorce and fight through the courts to get my house that I own back. For legal reasons, I have had to pay all the normal bills for my house while my spouse has enjoyed the benefits of that. My salary can't stretch to running two separate full households, and so my temporary accommodation has been the cheapest respectable arrangement available.

People fleeing domestic abuse with reasonable means need to have options, because the domestic violence shelters can't be expected to accommodate everyone for the whole time a divorce takes (which in some situations can be multiple years).

The political circus is drowning out some pretty clear science here. Let me break this down without the academic jargon:

The basic problem: Most studies can't tell the difference between the medicine and why you're taking it. If you're having Tylenol during pregnancy, it's probably because you have a fever, infection, or severe pain. Guess what also increases autism risk? Fever, infections, and severe illness.

What makes the Swedish study special: They compared siblings in the same family. Same genes, same environment, same parents - but one child was exposed to acetaminophen in the womb and the other wasn't. This controls for all the family-level stuff that usually confuses these studies.

The numbers tell the story: - Regular studies: "5% increased autism risk with acetaminophen" (HR 1.05) - Swedish sibling comparison: "Actually, no increased risk" (HR 0.98, could be 7% protective to 4% harmful - basically noise) - Meanwhile, untreated fever: 40% increased risk, multiple fevers: 212% increased risk

We have evidence that fever during pregnancy messes with fetal brain development. We have the best study ever done showing acetaminophen doesn't cause autism. So we're going to... stop treating the fever?

It's like refusing to use a fire extinguisher because you're worried it might stain your carpet, while your house burns down.

The Swedish study should have ended this debate. When the science is done correctly, the acetaminophen "risk" vanishes completely.

The GP comment is technically correct, if somewhat incomplete. A 40 m3 room (about 14’x14’x8’) has about 50kg of air in it; that’s only ~300 Wh to heat every molecule of it by an entire 20C. The thermal mass of the other things is orders of magnitude larger.

The reason that I consider that explanation somewhat incomplete is the behavior of the air and the embodied energy. Imagine it’s winter, the exterior air is quite dry, and you open a window. You will easily lose a large amount of moisture, making the air uncomfortably dry. So you turn on a humidifier, but that will cool the room further with the evaporation of water. You also have to consider convective heat transfer. The fast-moving air is quite good at transferring heat to the outdoors. So, even if you don’t care about humidity, you will lose a lot of heat through convection.

But yes, strictly speaking, the thermal mass of the air is very low in most structures and situations.

Interesting, I knew SROs were not allowed in most places in the US, but never clumped roommates in with that. All the places I've lived I had no problem sharing apartments let alone houses with roommates. I wonder if the laws distinguish from roommates chosen by tenants, vs multiple tenants chosen by the landlord, or if the places I've lived allowed SROs, or if the law was just commonly ignored.

Yeah I'm not sure why the title of the link v the article is different.

> Officials also warned of the havoc the network could have caused if left intact. McCool compared the potential impact to the cellular blackouts that followed the Sept. 11 attacks and the Boston Marathon bombing, when networks collapsed under strain

It's more of a warning of potential attack, there is no real 'hobby' use for this kind of infrastructure. I wonder if it the 'cell tower' service isn't also used for higher priority coms though. I'd like to know more of the hardware that was used here.

> The problem is when a large amount of abusive traffic comes from a handful of countries, it's technically easier to block entire IP ranges and ASNs

Abuse is becoming a much bigger problem lately, to the point that even large western providers are getting the same treatment nowadays. More and more I see people talking about banning Hetzner, OVH, DigitalOcean, and at any given time I can see several of their IP addresses in abuse reporting websites (spamhaus, abuseipdb).

What is the future here? I see no reason for those providers to tighten on abusers, given how long they’ve already ignored it. Pretty sure at some point you’ll have to have your own ASN and IP ranges to be able to do anything on the internet.

> newer AVX-512 variants as opposed to older AVX2-only CPUs

This is exactly my issue with targeting AVX-512. It isn't just absent on "older AVX2-only CPUs." It's also absent on many "newer AVX2-only CPUs." For example, the i9-14900K. I don't think any of the other newer Intel CPUs have AVX-512 either. And historically, whether an x86-64 CPU supported AVX-512 at all was hit or miss.

AVX-512 has been around for a very long time now, and it has just never been consistently available.

This last wave of work was actually triggered by the industry over the last 2 years, as the volume of biological sequence data is growing rapidly and more BioTech and Pharma companies are rushing to scale computational pipelines.

Namely, if you look at DeepMind’s AlphaFold 1 and 2, bulk volume of compute time is spent outside of PyTorch - running sequence alignment. Historically, with BLAST. More recently, in other labs, with some of my code :)

I looked it up rapidly and couldn't figure out the difference with the original OrangePi 5.

By the way, the OrangePi 5 is a pretty good SBC. Much better bang/bucks than RPi, and the mainline kernel support is pretty good and getting better with every release thanks to the folks at Collabora.

> people living in them should just try not being to poor to have real housing

Yes, unironically, they should. And most would be trying to do exactly that.

I don’t know why some people treat economic status as some immutable property outside of your control. People move up and down in economic status all the time. And most people move up as they get older and get more work experience and higher paying jobs.

Having a stable place to live with a physical address instead of a tent, and possibly being around other people who are trying to improve their lives instead of a bunch of drug addicts would absolutely help people “not be poor”.

`Arc`s show up all over the place specifically in async code that targets Tokio runtime running in multithreaded mode. Mostly this is because `tokio::spawn` requires `Future`s to be `Send + 'static`, and this function is a building block of most libraries and frameworks built on top of Tokio.

If you use Rust for web server backend code then yes, you see `Arc`s everywhere. Otherwise their use is pretty rare, even in large projects. Rust is somewhat unique in that regard, because most Rust code that is written is not really a web backend code.

Well, yes, actually. That does seem to be the way of the world. Look how many 1%ers only make donations based on PR recommendations to keep their image in good standing. Funny you made a Pope joke, but it is common for people attending the Church to pay donations for absolution. As for your murder cost question, I guess that depends on which ad in the back of Soldier of Fortune you replied.

> As far as I can see this is a non-Governmental non-profit doing this. So it has no legal merit.

It has no legal weight. Lave of legal merit is a feature of a legal argument and is missing if the argument improperly represents the law, not if it comes from a source that doesn’t provide it legal weight. (Since you later say you agree with it. that is equivalent to saying that, insofar as it is a legal argument, that argument does have legal merit.)

> Can’t tell if this is the ad industry attempting to self-regulate?

No, it is a non-advertising industry non-profit doing research and reporting to the public, which potentially puts political pressure on government actors (State Attorneys-General and, maybe, the FTC) to take action (it could also provide ammunition for private lawsuits, except COPPA doesn’t provide a private cause of action.)

Note that a part of COPPA regulation is a Safe Harbor provision which involves industry self-regulation and certification, but that only protects against FTC, not state, action.

>> Where are these types of places illegal in reality?

Because eventually individual rooms start being rented by families. Next you have four families living in a single-family occupancy location and there is a huge fire hazard. I've seen this happen in NYC growing up, and its super dangerous. I also empathize with the other side -- as a poor person you may have no other option.
