I like the idea that it is “pretentious” to predict — without evidence as you’ve pointed out — that getting hit by a 6,600+lb vehicle is bad but it is not pretentious to confidently predict without evidence that getting hit by a 6,600+lb car is the same as getting hit by a different vehicle that is one to two thousand pounds lighter.
One wonders if they are worth face value given inflation. It would be a fun exercise to figure out their value in pounds sterling and then calculate what that number would be in the present.

Not so much in terms of meaning but in terms of pronunciation, sometimes you also need to read ahead in English to know how a certain word is pronounced. For example:
"I read a book yesterday."
and
"I read a book every night."
Depending on the context that follows, "read" is pronounced differently. The same thing happens for "present" and "record". Admittedly, these are exceptions to the rule.
I had the same experience when I lived in Germany back in the 80/90s. All the infrastructure was underground so the only time we had a power outage was when someone was digging and hit the line. I always bring this up now days living in Georgia where a strong wind can knock out power for a few hours.
This article is a good excuse to get rid of outdoor advertising for safety reasons.

I was watching some tours of some very nice metro stations in China and Moscow. I didn't quite understand what was so nice about them until one comment pointed it out: no advertising blasting bright colors into your retinas. Advertising in public spaces needs to be banned. It's visual pollution and it's using publicly funded assets to make tangible profits while the losses are externalised easily because they're not well understood.
If profit is all you care about then it's easy to justify turning your house into a brothel.

Because "honest curiosity" is so often used as a DDoS vector.

Most people are not convinced by rational argument. Aristotle covered this more than 2000 years ago and human nature has not changed.
I think that the problem is that theoretical real analysis is often presented like it's nothing but a validation of things people already knew to be true -- but maybe it's not?

The example you gave concerns differentiation. Differentiation is messy in real analysis because it's messy in numerical computing. How real analysis fixes this mess parallels how numerical computing must fix the mess. How do we make differentiation - or just derivatives, perhaps - computable?

The rock-bottom condition for computability is continuity. All discontinuous functions are uncomputable. It turns out that it is sufficient, to make your theorem hold, to have the 2nd partial derivatives f_{xy} and f_{yx} be continuous. They wouldn't even be computable otherwise!

One of the proofs provided uses integration. In numerical contexts, it is integration which is considered "easy", and "differentiation" which is considered hard. This is totally backwards to symbolic calculus.

The article also mentions Distribution Theory. This is important in the theory of linear PDEs. I suspect it is implicit in the algorithmic theory as well, whether practitioners have spelled this out or not. This is a theory that makes the differentiation operator itself computable, but at the cost of making the derivatives weaker than ordinary functions. How so? On the one hand, it allows to obtain things like the Dirac delta as derivatives, but those aren't even functions. On the other hand, these objects behave like functions - let's say f(x,y) - but we can't evaluate them at points; instead, we can take their inner product with test functions, which we can use to approximate evaluation. This is important because PDE solvers may only be able to provide solutions in the weak, distribution-theoretic sense.

The fact that 嚔/sneeze is usually the go to example means it ends up becoming the exception that proves the rule. Most other characters are much more easily remembered.
Yes, I endorse his research. As a Taiwanese, I use Traditional Chinese daily in Taiwan, primarily on computers and mobile phones, but I can’t write many of the Chinese characters he mentioned in the article.

I can share a more personal story: after spending a year studying abroad in Britain, I almost forgot how to write Chinese characters—even my own name—since I hadn't written any for over a year! However, when I returned to Taiwan, I was able to recall most of them within minutes. I consider this a temporary phenomenon that fades quickly with focus and a bit of practice.
> It takes about 10 seconds or so to set an image in your mind of the scene for a character, then a handful of reviews over the following weeks. Then you never forget it.

As someone with experience using the Heisig method, I would strongly disagree. Yes, it is a helpful system to ease the burden of memorization, but it does not permanently embed this knowledge into your memory after "a handful of reviews over the following weeks". If this were true, there would be many, many more people who have memorized 4000+ Chinese characters, required for fluency.

Dark Matter is a name for set of observations that aren't explainable with currently accepted cosmological theory. There are many possible ideas of how Dark Matter problem can be solved. Why do you think making fun of specific idea of what might be the cause of Dark Matter problem or even the Dark Matter problem itself is problematic? Did suddenly the deficiencies of current state of science became not funny? Modifications to gravity are one of the possible solutions to Dark Matter problem (just as Machos and Wimps are) but not especially good or plausible ones and deserve being joked about just as much.

You can learn more about the problem from this physicist: https://www.youtube.com/watch?v=qS34oV-jv_A

> Inflation has no influence on galaxy formation.

That's completely not what I was talking about. I was saying that the era of rapid inflation that despite being postulated to be just a fraction of a second had immense impact on the shape of the universe can't be swept under the rug just because it's short and is already a kind of "Dark Time" when huge things were happening despite time barely passing.

You could equally sensibly postulate that 500 million years since the Big Bang there was a fraction of a second when galaxy formation underwent accelerated progress that aged them few billion years and that explains early black holes and such. Hopefully it won't come to that and more sensible explanation of what JWST sees will prevail.

It's true that "dark age" is not talked about in cosmology and is and invetion of the downvoted user. However when you think about it this naming analogy makes perfect sense when there seems to be missing mass it's called dark matter (which makes sense since it looks like the mass is there but it isn't shining), if there's missing energy it's called dark energy (despite the fact that we don't expect it to be shining in any way)... by extension when there's time missing we could call this problem dark time (witch is about as sensible name as dark energy) ... It's a case like scandal in Watergate hotel and then naming all scandals something-gate.
You say that “if the spacetime is moving, there’s local curvature”?

Then, in flat spacetime, as there is no curvature, then (by the contrapositive) there is no “movement of spacetime”?

But if some stuff is not moving in one inertial frame, then in another inertial frame it is moving.

But that implies that, if spacetime is stuff and such that, if it is moving then there is local curvature, it follows that in a different inertial frame, the spacetime is not flat.

But, whether spacetime is flat doesn’t depend on the choice of an inertial reference frame.

As for how to describe those things without talking about spacetime moving,

How spacetime works has the general coordinate invariance or covariance or whatever.

You have a manifold with a pseudo-Riemannian metric tensor. You can talk about like, geodesics and such.

For a warp bubble (suppose a sub-luminal one) you could talk about a non-accelerating time-like path that remains within the bubble, and talk about how the spacetime interval along it relates to the spacetime interval of some time-like path that starts in the bubble, leaves it, “travels besides it”, and finally re-joins the original path.

(Of course, in some reference frame, the bubble would not move.)

I don’t think it really makes sense to talk about spacetime moving, even in the case of a warp bubble. A position doesn’t have a position, or a time a time, but rather a position is a position, and a time is a time.

You can talk about how, in some particular coordinate system, with some particular foliation into space-like slices, some aspects/pattern of the metric tensor at some position and time coordinate values, correspond to those at a later time coordinate at a different position coordinate value, but this is relative to a choice of coordinate system.

fwiw I studied Japanese, but I believe most of this still applies.

It's divide and conquer. When you are reading the book, you are indeed just learning the characters. It's a significant ~2-3 month investment that maybe doesn't make sense unless you plan on living and working in the country. But once you've gotten through it, it absolutely feeds back into vocab acquisition, since the characters are now completely unambiguous to you. Much like how Latin/Greek helps with English, you can also work out what entirely new words might mean if you are familiar with their characters.
That's the closest link I could think of, but "deadlifting" is at best a very specific and small step toward the implicit goal of "become immune to all physical harm". It doesn't make sense, so I figure there has to be something I'm missing.

I've used mastodon for years before the twitter thing and there was always a lot of content and engagement. It may have been more niche groups/servers talking about niche things which was great.

With the twitter exodus, I was afraid that it would lose that, due to the sheer amount of ex twitter people joining and posting about nothing of interest.

But it didn't happen. It's still as great as it always was. Imo it's actually much more like hacker news than like twitter. Though maybe it depends on who you interact with.

> In my view, if a compiler optimization is so critical that users rely on it reliably “hitting” then what you really want is for that optimization to be something guaranteed by the language using syntax or types. The way tail calls work in functional languages comes to mind. Also, the way value types work in C#, Rust, C++, etc - you’re guaranteed that passing them around won’t call into the allocator. Basically, relying on the compiler to deliver an optimization whose speedup from hitting is enormous (like order of magnitude, as in the escape analysis to remove GC allocations case) and whose probability of hitting is not 100% is sort of a language design bug.
>
> This is sort of what the article is saying, I guess.

I agree with this to some extent but not fully. I think there are shades of grey to this -- adding language features is a fairly complex and time-consuming process, especially for mainstream languages. Even for properties which many people would like to have, such as "no GC", there are complex tradeoffs (e.g. https://em-tg.github.io/csborrow/)

My position is that language users need to empowered in different ways depending on the requirements. If you look at the Haskell example involving inspection testing/fusion, there are certain guarantees around some type conversions (A -> B, B -> A) being eliminated -- these are somewhat specific to the library at hand. Trying to formalize each and every performance-sensitive library's needs using language features is likely not practical.

Rather, I think it makes sense instead focus on a more bottoms-up approach, where you give somewhat general tools to the language users (doesn't need to expose a full IR), and see what common patterns emerge before deciding whether to "bless" some of them as first-class language features.

> And all the studies (that I'm aware of, at least) using psychedelics and therapy to treat mental health conditions don't use doses high enough for the kind of trips they can create those experiences - the goal is to have a strong enough effect that the brain and its thought patterns are more malleable than usual, but not so strong that the patient focussed on the trip rather than on the talking therapy.

I think you’re misinformed on this. Most modern psychedelic research is not focused on actively participating in therapy during the psychedelic experience itself. Typical doses used in trials are actually very large — verging on a “heroic dose” in some cases. E.g. see: https://bigthink.com/series/the-big-think-interview/psychede...

“My therapeutic research with psychedelics is primarily used 'psilocybin,' which is the agent in magic mushrooms. The dose we now give to patients is anywhere from 30 milligrams to 40 milligrams, which Terence McKenna, who's the famous psychedelic bard would refer to repeatedly as the "heroic dose."
This is because pharmacology is a shell game, where there is a constant pipeline of new chemicals being rotated in as soon as they're "recognized as safe". That is because people start to notice the adverse, toxic effects of the "old and busted" chemicals, such as Thalidomide or Phen-Fen, aren't such the "miracle drugs" they were cracked up to be, so there needs to be a constant stream of new stuff to replace it. They simply need to approve drugs a bit faster than attorneys can file class-action lawsuits.

https://en.wikipedia.org/wiki/Fenfluramine/phentermine

Another effect is that the "new stuff" is a weak synthetic facsimile of whatever the previous drug generations were, and eventually you end up with 100% fake treatments, often doing the opposite, exacerbating and magnifying the very symptoms they're prescribed for, or damaging the target organs/glands, and shutting them down.

"Fail first" or "step therapy" policies by insurance carriers will aid and abet this behavior, as the prescribers are forced to begin with inexpensive and ineffective (or harmful) treatments before they can even propose a treatment that is deemed efficacious.

https://en.wikipedia.org/wiki/Step_therapy

So, yes, my comment about people high on amphetamines was relatively tongue-in-cheek, because physicians are seldom incentivized to get people high these days: they're incentivized to push the new hotness wonder-drugs that people haven't figured out are just as horrible as the old ones.
> By "target system" you mean "system from which the password originated", right?

Yeah that’s correct.

> The phrase "stored on Earth" is a red herring. You don't need to store all possible passwords for those passwords to be possible to generate here.

A password used to protect a system must be persistently stored inside that system.

The number of passwords that can be generated on earth is greater than the number that can be persistently stored on earth.

For example, an iPhone must locally store a user’s unlock PIN code. However, it could theoretically generate a 20TB password for an external site in chunks without ever storing the full password locally.

Energy is a binding for password generation; but size is a constraint for password storage, which likely kicks in a lot earlier.

From the Reddit's transcript, https://www.reddit.com/r/SpaceXLounge/comments/1gc7rex/comme...

> Right at transsonic, which is like just before engine startup, one of the chine covers ripped off. Which is something we were - we were worried about these spot weld margins on chine skin right before flight, we wouldn't have predicted the exact right place, but this cover that ripped off, was right on top of a bunch of like single-point-failure valves that must work during the landing burn. So thankfully none of those or the harnessing got damaged, but, we ripped this chine cover off over some really critical equipment right as landing burn was starting.

So, they had single-point-failure valves - which didn't fail - and they had protective cover - which failed. Overall they didn't really had single point of failure, and - while two specific failures in a row could cause an extensive failure - those two-in-a-row failures didn't materialize.

> We have a plan to address that.

Good, since it looks like the first failure was considered of a rather high probability.

Coming back to the 1 second from the abort situation. The first order approximation of Super Heavy mass distribution is relatively simple, and with such model predicting how it would behave in the air when responding to random external forces is rather possible. Terminal control, which has a goal of getting to caught by Mechazilla situation, can reasonably determine the necessary difference in forces which needs to be applied, with reasonable margins - for future random forces, for variations of performance of actuators, for model errors (keep the ship closer to the middle of trajectory so more subsequent flight control is possible). Given reasonable excess in hardware - that is, there should be multiple sensors, multiple RCS engines and e.g. duplicated intermediate systems - and assuming the hardware won't fail too fast, this first order model would allow control of last seconds of the flight with reasonable assurance. The more realistic model could be built using real data on the Super Heavy dynamics accumulated both in previous flights and in this flight. And the failures in the algorithms could probably be guarded against by a sort of digital "check list" - I understand that checking something could be error-prone, so computers should really help here.

This all is of course from the proverbial armchair of an interested and empathizing observer.
Yeah, as a last resort that is a good suggestion. On a proper computer you could even use "save page as" and have it run the javascript so you can use all of the functionality (e.g., checking items off, or temporarily hiding when you're planning to get them in the next store) except that the syncing will fail until you get back home, which would be okay then.

It's a rare situation though, otherwise it would have been worth it to make a proper app that caches all data locally rather than a webpage
