I bet part of it is the dopamine response of getting a lot of likes combined with the uncertainty of when or if you'll get it again.

That's the crux of the skinner box, right?

If you make a post that gets 100+ likes more than usual, it feels good. "I am so smart. I am so clever. Everyone likes me!" you get to say to yourself as the likes roll in.

Then, the feeding frenzy is over and you're back to being you.

Anything that feels good can be addictive. Get enough people whose whole lives revolve around getting dopamine responses from positive social media interactions and you'll have a bunch of people who have MK Ultra'd themselves into being the zombie patsies of a bot farm who provides them with the dopamine they live for as long as they do the things your bot farm has told them to do.

Spin the wheel up enough and let it fly.

Rinse and repeat and you can have an army of happy and well-paid misinformation soldiers at your beck and call backed up by a horde of dopamine junkies willing to say or do almost anything to keep the dopamine flowing.

It's quite terrifying once you step back far enough to see the whole thing.
yes i get that, but say you have an indoor temp of 30c and an outdoor temp of 0c. the average of this heat exchanger is going to be 15c. so on average youre only cooling the exhaust down to 15, and heating up the intake to 15c.

a counter flow heat exchanger can get the temperature higher than the average because 30c exhaust is meeting partially warmed intake, and 0c intake is meeting partially cooled exhaust.

Unless theres a phase change???
I understand that the addition of desiccant material is the core aspect of what makes this an ERV. I don't actually see any clear explanation of how the desiccant material is added to the printed part. While the creator (open_erv2) mentions that sorbent/desiccant can be used to handle moisture ("If you have sorbent, it gets grabbed out of the air before it can condense"), they don't specify how it's incorporated into the design.

Is it added mid-print? After printing? Is it difficult to add?

Hello,

I'm going to answer this is good faith, but I suspect you know exactly what I am talking about. I meant people in the plural, generic categorical sense - in the context of the public discourse. I am not picking out this author in particular, but the rather the institutions such as MIT Technology Review that frame the public debate. As an example, see how the NY Times covered these stories - that is what I meant by people - the people who contribute to the public debate.
One of the announcements from AWS this year at Re:invent is that they now can guarantee that the instances clocks are synced within microseconds of each other. Close enough that you can rely on it for distributed timekeeping.

And it is not even expensive to a full type 1 civilization on the Kardashev scale. We just need to hack some genes to not require exercise to develop muscle mass. We already can do it with drugs, and we probably could do it genetically if it wasn't for safety and ethical concerns. As for the cost, I expect a Type 1 civilization to be able to fix genetic diseases as a routine operation, and they could fix muscle atrophy at the same time, if desired.

Muscle mass requires more energy, but by definition, a Type 1 civilization has no shortage of it. And I expect making food out of thin air (like plants do) would be the kind of technology such a civilization would have.
Is there some generalized law (yet) about unintended consequences? For example:

Increase fuel economy -> Introduce fuel economy standards -> Economic cars practically phased out in favour of guzzling "trucks" that are exempt from fuel economy standards -> Worse fuel economy.

or

Protect the children -> Criminalize activites that might in any way cause an increase in risk to children -> Best to just keep them indoors playing with electronic gadgets -> Increased rates of obesity/depression etc -> Children worse off.

As the article itself says: Hold big tech accountable -> Introduce rules so hard to comply with that only big tech will be able to comply -> Big tech goes on, but indie tech forced offline.
> I'm going to get a trimmer, so I want a thoughtfully designed and well made version of that.

OK, those are three quite different things.

Modelica allows you to create models in a similar way to spice by describing components and how they are connected. But instead of a netlist of nodes, Modelica has a concept of connectors. But otherwise it is fairly similar. However, Modelica's scope is well beyond that of Spice or Verilog-A. Those languages claim that by analogy they can do other domains but you are mainly limited to simple "equivalent" circuit models for thermal systems and their analogies to mechanical systems are (in my opinion), hopelessly flawed. Not to mention that there are high quality libraries in Modelica for modeling multibody systems and two phase fluid systems...things I would never attempt in Spice or Verilog-A.

As for Simulink...that is an entirely different beast. Simulink's focus is on modeling of dynamics using a representation of the _math_, not the physics. What this means in practice is that when you build a model you translate the text book equations into a _causalized_ mathematical representation of your system. The problem with this is that changing even very basic assumptions will require you to re-causalize the system of equations and this is quite tedious, time-consuming and error prone. The way I always describe it is that Simulink is like performing long division (you do all the tedious, time consuming and error prone work yourself) whereas Modelica is like a calculator (it does all that stuff for you and just helps you get to the answer quickly). But the key point about Modelica is that it leverages a compiler that does a ton of work for you (not just causlization but state selection, index reduction, etc). Now MathWorks has Simscape that supports this "acausal" approach that Modelica uses, but in my opinion Modelica is not only technically better and more powerful, but also more open (see OpenModelica, for example).
Nope. Actually, none of the nuclear reactors in Germany are restartable. By now, all of them have had their permit to dismantle for some time. In all of them, they already started sawing apart the less radioactive components and flushing the rest with agressive cleaning agents and sticky goo to get rid of mobile particles that could endanger the workers. Which means that none of the reactor components are in any usable state and would need to be exchanged for new ones. Doing that in an old reactor is more expensive than building a whole new one, and would probably take a lot longer.
Might the author be overreacting a bit to this new law? As I understand it, it doesn't put that much of an onerous demand on forum operators.

Then again, maybe he's just burnt out from running these sites and this was the final straw. I can understand if he wants to pack it in after so long, and this is as good reason as any to call it a day.

Though, has no-one in that community offered to take over? Forums do change hands now and then.

>> The cost of Linux kernel development alone has been estimated at a few $B (https://dwheeler.com/essays/linux-kernel-cost.html), current figure is probably over tens of billions.

I followed your link, but it doesn't seem to bear out upur assertion. The two numbers mentioned in the article are
176 mil and 612 mil. Mind you those weren't an estimate of cost, but rather an estimate to replace. Article is dated 2004, with an update in 2011.

Using the lines-of-code estimation it crossed a billion in 2010 - again to replace. That has no relation to what it did actually cost.

Getting from there to "tens of billions" seems a stretch. Assuming a bottom value in your estimate of 20 billion, and assuming a developer costs a million a year, that's 20 000 man-years of effort. Which implies something like 2000 people (very well paid people) working continuously for the last decade.

Which seems, well, unlikely.

Nothing in this article suggests that the nation actually wants more children than it is producing. Rather, we have quotes from demographers and politicians, speculating about the consequences of a change in fertility rates, and some of those people appear to wish that the nation wanted more children.

I worked at a very well known news company. Their auth proxy layer was set to “fail open” for a period of time if there was any issue detected in the auth backend (i.e. just return ok and a new cookie for 30 seconds). When I checked the logs that system was in a fail-open state over 50% of the time.
This is pretty typical. The first step of CAD is learning simple solid modeling (i.e. producing 3d parts from sketches, features, etc).

The next step is assemblies and motion. Writing a solid modeling CAD engine is impressive, but kinematics and simulation is really the tough part (and why these CAD softwares are so expensive and so worth the money). For example, SolidWorks has a separate "motion study" package that you pay for on top of the solid modeling tool, a separate "fluid simulation package," to calculate stresses, drag, and so on on a part. Assemblies are also huge, most CAD programs have utilities for creating relations between different parts to figure out where screws, clasps, hinges, etc, should go where and in what order.

Many professional CAD packages also have things like mold tools, sheet metal tools, etc. that make manufacturing much much easier. You typically have a drawing tool, to create marked up drawings to send off to a machine shop for fabrication. Manufacturability is huge and mostly invisible to hobbyists who are doing 3-d prints. In general, software that makes manufacturing stuff easier, is where CAD packages capture the most value from their users. The manufacturing stuff is why you might pay $5,000 per year per seat for a CAD suite. It's also why they're not too worried about open source CAD, because the open source guys don't care, or know enough to care, how to add this type of value.

Finally, the big big boys (like CATIA and so on) have utilities to track part revisions, quality tracking, assembly and QC workflows etc. For when you need to manufacture hundreds of thousands of something, test it, have it fail in predictable ways, manage spare parts for it, be tracked and regulated etc. Those are generally used for stuff like cars and jets which have complex supply chains.
The 20-year-old is, maybe, just like you at that age: eager and smart, but lacking experience. Making bad decisions, bad designs, bad implementations left and right. Just like you did, way back when.

But you have made all those mistakes already. You've learned, you've earned your experience. You are much more valuable than you think.

Thanks for this reply!

You’re right to call out just how enormously expensive nuke boats are. Anything carrying around a nuclear powerplant for that matter. They are the modern day battleships (Just see how the US Navy names theirs). For AUKUS, I tried to keep my argument to the warfighting value of the boats separate from the economics. But there’s a whole line of argument there you call out, which I think finalizes with the question “Can Australia afford to build forces necessary to participate in a Pacific conflict away from its shores?” Not off the Australian coast, but north of Indonesia where they envision defending Taiwan, protecting the Malacca strait, etc. I don’t think that’s an easy question to answer. I don’t think their previous plan of getting new AIP boats was a good one if that was their aim. But it’s fair to question if they can afford nuke boats either.

I disagree that rocket forces can be a stand-in for submarines. They’re great defense weapons: certainly for shore defense, questionable for longer distances that that (I’m making an obligatory nod to China’s ballistic anti-ship efforts), and of course, air-launched AShMs were a primary threat during the Cold War. But these all lack persistence, and require a lot of effort to target the thing on the other end; something made much more difficult the further away it is. And that’s the thing a submarine VLS cell gives you that an air-launched or shore launched missile doesn’t; It’s right there. I don’t think the subsonic speed is much of an issue when it pops up 10km from your task force. It’s the persistence, the endurance, that gives submarines (and surface ships for that matter) their role that land and air based missiles can’t. The latter can make things painful, but they can’t truly control a body of water for duration in the way those platforms can.

But you’re right to point out that China’s math is likely different than that of say, the U.S., because the latter has to come across the Pacific to do so. Force projection is expensive, and this is the challenge facing Australia. The U.S. can afford to do it (though I think it’s slipping in this regard), other major militaries such as the U.K. are facing hard questions about just how global they want to be. Australia is far enough away that if they want to help in those aforementioned scenarios, they need to bring the fight north, and that’s an expensive prospect for a country of just 24 million.

The last thing I’ll mention is while I think your points about the challenges of operating in the South and East China Sea would be very difficult in the face of enemy ASW, those submarines would not be operating alone. They operate as part of a whole (land, sea, air). It's not the pacific submarine campaigns of WWII and lone wolves hitting shipping. Though if it turns into that, we’re in real trouble.
I spent some time looking. There were some pricey "designer" ones, but they generally got poor reviews. Maybe it's easier to do a design-school exercise, than to get the phone guts engineering right. Also, mandatory VoLTE eliminated a lot of high-quality legacy devices that would've worked fine.
Agree, we do not need to turn everything into a profit center. Rural areas will be the most harmed by this because the costs are higher per capita from the lower density. The move seems in line with the broader pattern of pushing govt services into the private sector. Another example is wanting to remove the IRS provided free efile
Dude, quoting Ayn Rand once is bad enough. Referencing Atlas Shrugged repeatedly? Instant cred wipeout.
but there is additional risk and liability, because the new act creates more work in order to be compliant (which is what increases the liability), and it increases the risk of being attacked.

there's never been an instance of any of the proclaimed things that this act protects [...] people from, so he should be safe, right?

but despite this, he is already being attacked, and those attacks will not just continue but they are likely to increase because the attack surface has become larger.
I think laws and regulations can be put in place that, while imperfect, would highly discourage the use of social media by minors.

I wouldn't want every user to validate their age with government ID.

But we can say schools should ban kids from using phones. We can say that large social media platforms need to whitelist content/creators that children are allowed to access. We can insist that social media companies throttle the ability for minors to scroll through videos at a dopamine addiction pace.

More generally and more applicable to the discussion, I think regulations for social media need to be applied proportional to the userbase and centralization of a platform, and target viral algorithms.

Old school message boards should be safe from government interference, broadly.

It may be time to research simpleX chat and Briar if we will maintain the ability to communicate without government filtering.

Nonstarter for many, myself included.

What happens if power fails or one unit stops working? Without valves, you could get unwanted air exchange through a non-operating unit. The commenters discuss various aspects of the design in detail, but surprisingly no one brings up this potential failure mode.
This is not really as simple as just going through the permutations. What this is in practice is a triumph of instrumentation. Before this, no one has imaged altermagnetic domain structure. The behaviour of these materials is intrinsically linked to what happens in the micro- (or nano-) structure.

There are two challenging things here that makes this a discovery. One, making the material, which is extremely difficult to verify as altermagnetic due to the nature of measuring these materials. Two, the measurement, which combines two techniques to distinguish this as separate from antiferromagnetism.

It is a huge push forwards for the budding field since it provides a really nice way to go to a large-scale synchrotron with your altermagnet and study it in detail.
