This might be slow, but what about using the lift gas in a fuel cell with atmospheric O2 for extra efficiency? You reduce the lift gas in the bags, and if you store the water aboard then you get extra ballast. You could even “unload” the extra electricity for use groundside.

The corollary pipe dream here is to line the entire interior of the envelope as a fuel cell membrane and use the airship as a portable battery.
From Wikipedia:

"Bugorski continued to work as a physicist at the Institute for High Energy Physics and held the post of coordinator of physics experiments. Because of the Soviet Union's policy of maintaining secrecy on nuclear power-related issues, Bugorski did not speak publicly about the accident for over a decade. He continued going to the Moscow radiation clinic twice a year for examinations and to meet with other nuclear accident victims. He was described as "a poster boy for Soviet and Russian radiation medicine". In 1996, he applied unsuccessfully for disability status to receive free epilepsy medication. Bugorski showed interest in making himself available for study to Western researchers but could not afford to leave Protvino."
It's not hard to imagine that this kind of automated scanning might be used as an argument for that: "Clearly you had no expectation of privacy for information on your phone..."
In this modern age, you'll often come across synchronized digital clocks. Whether on your computer, phone, workplace, bank, etc. For me, it has become second nature to adjust my watch's time once every few days. I end up comparing my watch vs a clock a couple of times per day, and deciding the difference is great enough to fix, once a week or so (on a cheap, inaccurate Seiko 5, I would expect less frequency with a better timepiece)
Curiously refreshing. I’ve always thought there are a lot of psychos around, whereas most people I’ve encountered consider them to be outliers.
Particle accelerators aside, the quote at the end is a bit of an overstatement: "And as frightening and awesome as the inside of a particle accelerator might be, humanity has thus far survived the nuclear age."

The watch I have is rated to +-2 seconds a day. It'd take 15 months of not adjusting my watch to be 15min late.

That's pretty amazing to me that basically a spring and some gears can be that good at keeping time.
Funny concept, this made me think that any living organism is aware of NIL, therefore it's opposite. Also, counting and using numbers sounds quite absurd. I would pose the question on what numerical bases they "rely/behave/cognate/?".

This helps, but there's a time lag, and the person you voted for does not know why you voted for them over the other party. Letting your congressperson know that you care about it by calling them or writing them directly is much, much more effective at getting policies you care about implemented. You should vote (in every election!) because they know who votes and who doesn't, and want to make voters happy -- but you also need to know that this is an issue of interest to you.

Right now, here's a very straightforward way to do that for climate change: https://citizensclimatelobby.org/senate/

A common issue I've seen is more the return is replaced with a print statement. As a result, their code "appears" to working because they're still seeing the right values appear in their console when they run the code. If the function's returned value doesn't get used somewhere else, then they don't see where the issue is until points are deducted.

The main problem with using stat models or approaches such as deep learning is not that we are unable to do it. Though possibly trivial, the real problem is we are unable to understand how or why it works which can lead to unintended consequences or lack of ability to support/continue further development (aside from not being able to leverage the new fundamental understanding and apply it to related fields). Imagine if we left our understanding and working model of physics completely up to statistical and deep learning models. We would not be able to reliably design anything or model simulations ect.

The reason we have not figured out NLP is not because we are incapable, it’s because enough of the right minds have not been looking at it as a puzzle worth solving, possibly because it and other AI related concepts are often introduced at or just before the PhD level and so most minds in science never encounter it (even though they could never encounter any other written concept without it)
Good point!

Hey, this is just a share to see if anyone shares my interest. In my spare time, I have been kind of been making a videogame based on this question. (I’ve worked on sims professionally, but it is not most of my career.)

A “floating origin” and using alt dynamics is nothing new, but I’m a bit obsessed with weird sim physics in games. I had been playing around with a kinetic quadracopter dogfighting concept in godot engine for about a year.

Then the “tic-tac UFO” videos resurfaced, and I’ve been having a lot of fun imagining “how those physics would work” if reality happened to be as interesting as what Commander Fravor says he saw.

I doubt the UAP news is what anyone thinks it’s about, but I’ve made little simulations involving everything from spacetime warping to matrix-style “if you fly close to c.”

Sadly, it’s not a very rewarding game concept beyond “woah neat!” Gets me back to why I started programming, though.
Wow, bold statement. Can you give examples of things it does wrong?

Hopping Bonsai pots are hardly automation, they're a one-block fix item. Modded packs too often turn the game into Crafting Simulator, where your job is to click the right series of buttons to get the one block that does everything.

I think the best modded pack right now is the Create mod, because in it you use more flexible, more primitive automation tools like belts and shafts and gearboxes to build machines that do the work. You can have a contraption that does everything a hopping bonsai does, but instead of crafting it in JEI you have to assemble it in the world with deployers and timers and filters and so on.

Vanilla minecarts are useful for moving mobs, but not for actual mining.

If Google is being forced to search their users private data for fear of losing government contracts then they've purjured themselves in court by claiming otherwise.

If that were the case and Google honestly testified that they performed the searches based on the belief that the government would withhold business from them it is likely that the warrantless searches would be disallowed. Courts have found that even covert encouragement can apply. What matters is that the if it's functionally the government's choice if the searching does or doesn't happen, then its subject to the fourth amendment.

> "backends" (not "web backends", but the more general "where the mechanisms are") should know nothing about "frontends" (again, not web, but the more general "user interface of some kind"). This is really just MVC in its most basic sense. One good way I've found to think about this is to assume that there's always at least two UIs running simultaneously. Make sure this can work.

This is one I constantly struggle convincing my colleagues about. It becomes much more "obvious" if you are trying to write unit tests in C++ code[1], but unit tests are a mere side benefit. It's more about reducing coupling.

Currently working on a code base that outputs to an Excel file. We recently started dealing with more data than the Excel file can handle easily, and the system came to a crawl. So we had to allow for the option to output to CSV (easily 100x faster in our use cases). At least now some of my colleagues have a bit of appreciation on what I've been harping on.

The Excel library is still intrinsically tied to much of our code. We've been getting over 15GB RAM usage for data that I'm sure would not take more than 2GB if we manage to bypass the Excel library.

[1] Why does my class that computes X need to know that something called email exists? So to write a test for this class I need to instantiate a whole other set of classes just for output? Just have it "ReportMessage" on the Reporter interface and let whatever class that inherits from it figure decide if the message will go out via email or SMS.

You are mistaken. It has been achieved, and the fastest race boats today do it routinely. This is one of the reasons you don't see spinnakers on boats like the America's Cup AC72s, AC50s, F50s, huge open class trimarans, etc.

I'm not sure the first boat to achieve it, but it wouldn't be surprising if it was done during the Clipper era. Those boats held 24 hour records from 1860 something all thee way to the 1980s, where modern racing yachts finally eclipsed them.

> (humans are still machines, after all)

Good point.

> but I think this certainly points to why humans learn language so much faster than machine models. We can synthesize language understanding with a much richer, sensory-based model of the world and recognize that words correspond to clusters of sensations like specific sights, sounds, tastes, feelings, and smells.

Yes, because unlike computers, we have bodies that are in the world.

> A logical next step in AI research is figuring out some kind of way to get these various systems that do one thing and one well to interoperate the way all the parts of a brain do

Do you think it’s fair to conclude that until computers have bodies that enable them to have the same situational presence and sensory awareness that humans have, computers will fall short of being able to parse natural language the way humans do?

Are a (human like) body and senses sufficient or might more be required? I’m thinking of extinct animals - just because we can restore their bodies from their genomic sequence doesn’t mean we can ever restore their culture.

Humans learn culture through a lifelong process that necessarily involves an early stage of childhood dependency, then growth, and maturation.
I think it's a combination of effort and culture that leads to such differences in style; in C, creating objects and functions and overriding them etc. takes far more effort than it does in Java (where IDEs can also generate tons of code automatically), so programmers naturally think more about whether the additional effort expended is worth it. Asm is an even more extreme case in the C direction --- every additional machine instruction is explicitly written, and so is dispensed with if not absolutely necessary.

That said, I've also seen "object-oriented obfuscation" in C, so some people seem to just love complexity and writing tons of code to do a simple task, or were taught "abstraction is great, use as much of it as you can" and never thought about when to stop.

Overabstraction usually increases macro-complexity while decreasing micro-complexity; a function with a single line of code is "simpler" in that its immediate purpose may become obvious, but having to mentally stack from its callers means that the big picture is harder to comprehend.

At the extreme high end of density are languages like the APL family, where the density is so high that the "big picture" becomes a slightly smaller one, and Arthur Whitney has been famously quoted as hating scrolling; but at that density, you can no longer "skim" large portions of code --- instead, each individual character needs to be read and pondered carefully, because each one says a lot.
The lens library has a reasonably consistent visual language baked into it:

- Operators containing `%` apply a function to the target (mnemonic: % is "mod" in many languages).

- Operators containing `=` have a `MonadState` constraint and operate on the monadic state.

- Operators containing `~` operate directly on values.

- Operators starting with `<` pass through the new value.

- Operators starting with `<<` pass through the old value.

- Operators containing `@` operate on indexed optics (mnemonic: indices tell you where you are "at" in the structure you're traversing).

So an operator like `(<<<>=)` means "semigroup append something in the monadic state and return the old result". This is the power of a well-chosen symbol language, and I don't know how you'd do this ergonomically and compactly with only named operators.
Sport kites can also be great as a sort of demonstration of what a sail's crosswind potential could look like if it didn't have to lug around a vehicle, technically both downwind and upwind since they're essentially tracking a spherical concave shape centered directly downwind of the pilot. Speedkites in particular push the sail speed vs wind speed ratio to ridiculous limits. For scale, this kite is 190cm across.

This is vscode specific, but yarn suggests a zipfs extension which lets you explore the packages in exactly the same way you would with node_modules (with the added benefit of not having a massive file tree being expanded).
Most of his other books were very worth reading though.
I think this depends on the field. In physics and engineering, there is a body of underlying theory from which one can derive a hypothesis, based on some causal mechanism, before seeing any data. You can then go out and collect some data to confirm - in many cases this is basically just a sanity check, occasionally the data is in conflict with the underlying theory and you learn something big.

Outside of the hard sciences, your procedure could make more sense. We do this in business consulting (not always a science but it can be if you do it well) by looking through financial, operational and HR data and asking questions or trying to draw out interesting relationships that can lead to hypothesis for deeper examination. I would expect the same is true in lots of health science as well or any empirical field where we have data on outcomes and the characteristics that may influence then. Even in these fields though, it doesn't preclude starting with a causal mechanism based on underlying theory and then devising data collection and experiments to go out and conform or refute your hypothesis.

Personally, I've seen lots of cases where people are quick to rely on statistics and empirical studies, without looking for the mechanism that must exist behind the relationship they're claiming. Such findings are much weaker than results that may have less data or a bigger p-value but are grounded in actual theory and not just reporting a model-free relationship.

So to summarize, there is certainly a place for the order you suggest, but if done right, a stronger formulation can be made based on what you call the American school system method.
An awful lot of encroachment into forests is from high end subdivisions that should not have been built.

There's probably one written in Brainfuck too, doesn't mean it matters in the grand scheme of things though.

So, "at least one operating system programmed in Fortran" doesn't counter "Fortran hasn't been really used for systems programming", if that operating system is some irrelevant research project, or (as in here) a commercial niche system, that maybe ever reached 0.00001% of the OS users space.
it's original - i just made it up on the spot, but it may have been influenced by popular culture which mentions such ideas.
This is .. amazing? Using what essentially should amount to a strong typedef .. causes code to be millions of times slower.

Yes! This was a surprise to me to learn as well. I mean, it was in a different context (how to get to the sun), but the same issue applies, of having to shed a ton of angular momentum/orbital energy.

(If you're curious about the opposite direction, of objects with the least angular momentum, that would be either bosons, or Texas's four-day-long "rotating" power outages.)

>The vaccine can save lives too but it works best if as many people as possible to protect those who can't, to prevent breakthrough infections etc.

What works best is for sick people to stay the fuck home until they're not sick anymore. Healthy people's immune systems, won't allow a large viral load to allow for transmission. This is not a magic virus, there is nothing new here.

>I'm just not such a selfish asshat that I can give an hour of my time to go get vaccinated, reduce spread and maybe save some lives.

Homie, if you believe you're saving some lives by getting vaccinated...I don't know what kind of propaganda you've been feeding on along with those cheetos you were complaining about the other day.

The vaccine will not stop you from transmitting the virus to other immunocompromised people. Don't take my word for it, take Pfizer's.
Poor man.

But, uh.. are you and everyone you know dying of fireballs and/or radiation poisoning? If not, you are the one making the clear overstatement.
Right. The people mover is analogous to the wind. You can get to move at the windspeed through drag alone, at which point you no longer move relative to the air. The air is being robbed of only the fraction of energy that you're losing to drag (rolling resistance, as there is no air resistance now). This is you riding along with the peoplemover on the skateboard.

But then increase the rolling resistance - the generators on skateboard wheels -- but you still, by drag, move at the wind speed, you're just stealing more energy from the wind/peoplemover now.

Then you use that energy (simply by a chain linkage) to spin the propeller, blowing air aft. The propeller pushes air backward, changing the speed of the air molecules in the region behind the vehicle from whatever they were moving at, e.g. 10 knots relative to the ground, to 0 relative to the ground. That energy pushes the propeller and with it the vehicle forward, by Newton's 3rd law. This is the second electric skateboard driving forward, in the frame of reference of the peoplemover.

So now you're moving faster than wind speed, in the direction of the wind, stealing more power from the airstream (peoplemover) than you could steal by the (original) drag of your craft alone. You got there by increasing your rolling resistance, which won't slow your craft until the rolling resistance exceeds the available force from the wind. In the analogy, this would be equivalent to jamming your brakes so hard against the floor that you stop the peoplemover rail from moving at all. You use the extra energy -- the amount being spent by the wind to counteract your increased rolling resistance -- to push yourself faster forward.
The premise here is wrong, because lens operators are very much designed to carry meaning. See my sibling comment (parent->parent->sibling, I guess), but operators with `@` operate on indexed optics, and the leading `%%` means "modify, and collect summary".
Another difference between China (and the EU) and the US is that China (and the EU) have fairly serious plans to address the issue.

China plan is for emissions to peak in 2030 and then fall to reach net zero by 2060. They've just launched a big cap and trade system to support this.

The EU's plan is to reach a 55% reduction by 2030 and net zero by 2050. They too are going for a cap and trade system, to launch by 2026.

And the US? At the Federal level, we've got one major party that wants to do plans similar to the EU or China, and one major party that at best wants the government to do nothing and at worse wants to promote the increasing use of fossil fuels.

Whenever the first party controls the House of Representative, the Senate, and the Presidency we can get Federal action on climate change. But whenever that party loses any one of those the other party can largely stop them from further action. When all three go to that party, they can even reverse prior actions.

China has a very good chance of implementing their plan. The EU has a pretty good chance too. There is a good chance the US won't have a plan that can survive a party change for at least another generation.
