A funny one would be the height of the advertisement slots not always matching the height of the advertisements creating a large gap above the text under it while the text above is very close to it. You could make the space around the banner much larger so that above and below look more similar. If one does that, it still design tho?

Does Dr Zubrin actually have any model that can be peer reviewed?
If yes, what are the model's predictions?
How well have the predictions from the book (11 years ago) matched the changes that have been observed over the past 11 years?

Ok, I have not read that book, but according to reviews:

On “global warming”: Contrary to environmentalists, Zubrin holds that global warming is far from calamitous. Although he thinks global warming is real, he considers it to be of negligible effect; to the extent that it exists, he says, it is beneficial.

Does this track the past 11 years? Maybe someone should ask him what he thinks acount it now?

Huh, I just tried this with a couple of my bank apps and they do the same. I guess either I'm misremembering this, or it got fixes along the way.

Wallet is still accessible with the device passcode as a fallback though, which means quite a lot of damage can still be done.

Most written books are just people talking out of their ass as well, history is full of people publishing bullshit.
> That's exactly how C approaches UB too.

In theory yes. In practice it's been proven that's not what happens.

> The problem is that's untenable; any nontrivial program will have unsafe somewhere, and unsafe can cause failures arbitrarily far away from the incorrect code.

Not really. Ignoring any and all non-compiler tooling, UB in code can be traced to:
A) unsafe region in code where its invariants are invalidated
B) if no unsafe code exists in project, then an unsoundness bug in the Rust standard lib.

Safe code needs to be safe for any possible value of arguments, fields, variables. Doing otherwise is unsoundness bug.

In C, the code you need to look is essentially ALL of your code + C std lib. In Rust, you can focus on places where safe and unsafe code mingle. And IFF (if and only iff) your code contains 0 unsafe, can you be sure there is a Rust bug.

This however assumes any code.

Idiomatic code in Rust will treat unsafe with big large friendly letters `SAFETY: this works while X and Y hold`. How do you do this is C? Since most lines are possible source of UB do you annotate every line of code? I assume not. How do you ensure something will not be mutated? How do you ensure something is thread-safe? Do you use type bounds? And if not how?

> If Rust doesn't give you more and better support in doing that than C does, then it's not really making a difference.

Also that's the Nirvana fallacy, Rust doesn't have to be perfect and prevent EVERY undefined behavior forever. If it's improvement over the niche it's targeting (C/C++) then it's an improvement. I.e. is it harder to find UB in Rust or in C?

Like you don't go around and say, "Well seatbelts don't prevent head injuries when you hit a wall head-on. So remove seatbelts!", you add airbags to cushion the blow.

And spoiler alert: It's giving you the airbags as well. The normal thing when encountering a UB isn't to try to track it down it's to run `miri`, it found UB as soon as it ran.
Is this one of the oldest WMs still in development for Unices? I remember I ran Enlightenment on my Pentium 133 MHz Linux box to get those cool aliens hanging from my windows. Feels like the version numbering isn't much different from those good old days. What is the rationale for running Enlightenment today, compared to, say, a DE like Xfce?
But that's driven by the institutions and culture, like it's always been. A realistic accounting of the sheer scale of inequality and it's consequences shows that this is not in any way a new problem, or one caused by technology.

BTW don't know if I said this, but there are some reversible fans on digikey that should work. I was going to open them up and paint them with dielectric grease for water resistance. I ordered the 136 mm diameter one, they are pretty expensive and we will see how quiet they are.
love the initiative
You don't need to be an expert. Just look at what happened in Ukraine. Russia's results, or lack thereof speak for themselves.
The pilot is in control. But ATC will provide an altitude they want you to maintain. When you are cleared to land, ATC isn’t doing anything to keep the plane from hitting a building on final approach.

They vary considerably, the aliexpress ones are about as good, but none of them are very good, they give more like 70% efficiency at the medium flow rate, overall. Not what they claim. They do work though.

i think the solution to the viscous-drag problem is a fractal regenerator similar to a mammalian circulatory system, in which a branching tree of "artery" air passages feeds a set of "capillaries" distributed over a surface of high hausdorff-besicovitch dimension which separates the "arteries" from a second branching tree of "vein" air passages; this squares the circle of low air resistance (because the capillaries are short) with high heat flux (because the total surface area of the capillaries is large). if you have two counterflowing sets of capillaries instead of one, you have a rete mirabile recuperator

obviously this structure is not feasible to manufacture by conventional processes, but you can 3-d print it

cf. https://dercuano.github.io/notes/capillary-heat-exchanger.ht...

it seems crazy to me that people would use alumina as a regenerative medium for house ventilation; it's a pain to get into the shape you want, which makes it expensive in practice even though it's an abundant natural mineral. it does have an immense virtue as a regenerative medium, which is that it can withstand like 1750°, but if part of your house is over 1000° you have bigger problems to worry about than the efficiency of your hvac system. if you're trying to maximize the thermal mass of a stable solid per dollar, something like unfired clay is probably optimal, though it expands and contracts with humidity; lime mortar (quicklime and sand) avoids that problem. those are low thermal mass per kg; to optimize that, you'd probably want polypropylene instead (or paraffin wax, but it might melt)

unfired clay has significant moisture-adsorbent ability too, which is why it expands and contracts with humidity. muriate of lime is commonly used as both a (deliquescent) desiccant and a flocculant for clay colloids used as ceramic glazes; i'm not sure to what extent clay with muriate of lime in it can function as a solid desiccant

but maybe i'm missing some basic knowledge here, so plausibly these are stupid ideas; wikipedia is no substitute for experience

Any reason other than hyperbole that you consider Israel to be an apartheid state, as compared to the rest of the Arab countries?
Bach is definitely the greatest achiever in music of all time.

His fame also took a long time to establish. He was well known during his life but nothing like the mythical legend he is now today.
> History is written by the victors. The greatest achiever of which work reached us, by the criteria that we pick, of the things we know today, and the "we" changes from culture to culture.

I know you imagine that this is a profound observation but unfortunately it isn't. We all have it in our teens and twenties then we realise (decades later if we're unlucky) that it means much less than we thought.

We imagine that the work that reaches us now is so incomplete as to render present judgements about the past invalid or so inaccurate as to be misleading or useless. But culture and civilisation, are in a real sense, defined as what _endures_.

When it comes to the values that endure, it is more likely than not that humans pass along "the best things". Culture, after all, is downstream of genes and evolution.

There is no "better culture" hiding somewhere but hidden by our biases or by a conspiracy of victors. There are no better artists lost to the past who were so good that had they not been lost our knowledge and appreciation of art today would be far different and superior to what it is now.

"Acknowledging how biased is what we know" is similarly not as valuable an idea as it sounds because acknowledging bias doesn't actually reveal better information. The worst that bias can do is impede arriving at rational logical conclusions, and that is easily corrected by debate amongst enough people over a long enough period.

Another way to say this is we are always collectively evaluating stuff in the past based on the best information we have available now. To acknowledge a putative bias doesn't take you _outside_ of the sphere of our knowledge of the past in which we are making judgements because even the fact that you can think and utter that statement is a result of the cultural values that were given to you and are thus already a part of the culture.

There is nothing _outside_ of culture.
I don't think the problem is too hard. It's just that people don't seem to understand the different models and history of things.

People have this not-invented-here syndrome. It also comes from the fact that they initially think a certain framework is too complex. Only to figure out later that they didn't understand why certain things were done in a specific way. Also, the fame and opportunity that comes with creating a framework cannot be denied.

For example, The whole "MVC" term on the web is plain wrong (web2.0 times). It's a term from actual GUI programmer, bolted on a document presentation format.

These days it's probably faster and easier to distribute an OS such as MenuetOS via web assembly, and simply run a GUI application inside which uses a simple JSON api.

About statefulness... why are we introducing stateful applications which is then patched up with server side rendering when a simple html application would suffice? It makes no sense. It's stupid, costly, and has 0 benefits.

For more complex applications, sure.. but tbh, where are those? Is a simple admin panel or login screen really 10x more difficult to create than VS Code, or for that matter Microsoft Access?

"Engineers" in general like^H^H^Hlove^H^H^Hget off on complexity. That is where the problem lies. It's intellectual porn and toxic as hell.

You can 3d print one actually, it works pretty well. The only problem is the alumina has a higher volumetric heat capacity, of about 3.5, whereas PLA has 2.25. Which is pretty high. The thermal conductivity isn't a big deal, the main impediment to heat flow is in the air channel, not the solid material, plastic or ceramic. I commented elsewhere in this thread on how to print your own exchanger relatively easily. You can also get your own fans, so this begs the question of why you would pay $600 for them! Also you need a pair of them, you have to have two of those modules operating, one blowing air in and the other out at any given moment. Then they reverse direction. 70 seconds is a bit long for reversal time, it's better to make it shorter if you can. If you are diying one you can do that. If you try to mod an aliexpress one it's only going to cost more and probably not be as good to be honest, because you can't optimize it. Not hackable!
Ask any flight instructor, they'll all tell you the same thing.

The one thing they hate more than anything else is ab-initio (i.e. zero hours) student pilots turning up who've spent time on the computer flight sim. It always ends up with "the talk" where the instructor politely invites the student to put a stop to their sim career whilst they get some real hours under their belt.

Basic flight training is done VFR, i.e. "seat of your pants", based on visual environmental cues, combined with radio where required. The student learns to juggle the fundamental Aviate, Navigate, Communicate routine ... and its always evident who has come from a flightsim background, because they whilst they might be OK at some parts of Aviate they are scary at Navigate, shit at Communicate and just a complete liability when it comes to combining all three.

People coming from a flight-sim background have too many bad habits ingrained which need to be bashed out of them. Its a waste of everyone's time, and its a waste of the student's money because they are throwing money down the pan which could have been avoided if they spent less time sim.

Now, later on in your flying career. Once you get into instrument flight, then CAREFUL use of a flight sim can be useful. But in the end, there's still no substitute for real-life.

i'm surprised there's no humidity recovery; i'd think that, with a regenerator, humidity recovery is unavoidable even if you don't want it. maybe you're talking about cases where humidity or ΔT is so low that you don't get any condensation? https://news.ycombinator.com/item?id=38746150 points out that a little desiccant can solve that problem

Obviously, "it depends". In fact, in the article, a comprehensive list of criteria is given.
> To have degrowth, I have to question what measures are required to so disrupt the natural order of markets. Now, there are ways, you could use the law to restrict peoples options both legally and economically, but that is dystopian and regressive. Any governing body given the power to decide what goods and services others are entitled to, are violating those individuals human rights to things like free association and autonomy

Who owns natural resources? Is it a god-given freedom to pollute the environment and damage other people's lives?

Also:

> I think people waste because the concept of saving has been turned into a charade. I'll lose it gambling on an auto industry that looks ready for bankruptcy, or lose it when my short position gets blown out by a bailout, and itll be worthless when I need it if its in the bank, so ill buy a new $300 couch and plan to replace it in a couple years.

This doesn't sound as if you believe in a non-dystopian free market.

> Does democracy get to decide if you deserve a new car?

In a way, yes! What use is a car without car infrastructure? And also, apart from the indirect subsidies that make sure that we make more cars than anybody needs, and to perpetuate a need for more cars, there are direct subsidies to the industry, for buyers and makers of cars alike. Bad example.
Car traffic is much more heavily subsidized than public transport, especially when you start to factor in the beloved "externalities".

> In a market system, people can aquire goods and services in proportion to the value they create for others. It isnt decided from way on high, it is the product of a complex social system and the choices we make in it

Who decides if you are allowed to make goods and services by exploiting natural resources and polluting the environment?

Honestly, "market failure" and "externalities" are well-known concepts to economists. We just collectively decide to close our eyes.

the idea with the adsorbent is that you can get humidity exchange even when the ΔT isn't low enough to get actual condensation?
True, but FK (in child table) must reference a key (in parent), and most databases won't let you create a key without the underlying index.

The other direction, however, is not a given: most DBs will let you create a FK on fields not covered by an index, so deleting or modifying a parent can benefit if you create such index explicitly, because it can check for the existence of children much faster (and avoid potentially locking the entire table). Again, the access pattern governs what indexes are needed: if you never delete/modify parent, you may not need an index on FK (unless you also have some queries which can use it, of course).
> Comparison is the thief of joy

Comparing others is a source of joy, people love gossiping or just talking about who is better etc. Comparison is only a thief of joy when you compare yourself to others, but comparing Newton to Einstein etc is an endless source of fun, many people have enjoyed these discussions over the years.

Japan is a pristine example of that claim, the lack of growth and the inflation induced in a vein attempt to manufacture growth has been a sad comedy of national suicide.

Japan remaining politically cohesive at this time will be a footnote in the history books in the chapter right before "Yield curve control collapses", and the chapter will read "Interest payments on public sector debts increased as investor sentiment collapsed and the japanese government had to introduce crippling austerity measures to meet its obligations".

We have already seen the central bank there increase its interest rate targets because no one will buy the lower interest rate bonds. They are trapped under >250% debt to gdp, how do you think that gets paid off?
Life has undergone multiple large scale evolutionary shifts. Did it revert to the mean? Were multicellularity, photosynthesis, or sexual reproduction fads or blips?

Obviously fossil fuel use must be a blip, but non-fossil sources have achieved exponential takeoff.

This could be a new normal, with humans possibly being joined by synthetic AI lifeforms soon. This would represent a giant shift toward neural cognitive intelligent life as a dominant process in the ecosystem, a change similar in magnitude to the birth of eukaryotes or the Cambrian explosion.

Or it could all blow up and fail. I do not have a time machine or clairvoyance. I’m just pointing out that one cannot make definite statements about what complex evolving systems will do, and many very unprecedented weird things have already happened in the history of life.
