berndi··on Ukraine destroys more than 40 military aircraft in drone attack deep in Russia
Someone claimed they used fiber optic drones [1]. So perhaps the drones were connected to the trucks via optical fibers and the trucks carried the modems. That way, jamming over the airbases would have had no effect.

berndi··on Gene Hackman died of heart disease, his wife died of hantavirus 1 week earlier
> you're telling me it's possible to be functional enough to eat and sleep for a week, but not know that your wife is dead and the barking dog needs food and water

Absolutely, in late stages of Alzheimers you’re a vegetable, but basic bodily functions still work to some degree.

berndi··on US airlines transported passengers over two light-years since the last crash
Common sense means taking the less risky option.

Assuming that the survival rate is constant as a function of trip length, the empirical estimate of the risk is fully determined by the number of deaths per distance.

berndi··on The scary sound of Aztec skull whistles
I’m not a vegetarian or animal rights advocate, but an argument could be made that cruelty to non-human animals is similarly normalized in today’s world, perhaps seen as a necessary evil to satisfy our appetite for food or fashion items.
berndi··on US Olympic and other teams will bring their own AC units to Paris
Assuming a bedroom with surface area of 50 m^2 and an insulation R-value of 2 m^2K/W and an outside temperature of 30C, 300W would be required to keep the room at 18C. Cooling down 8 billion such bedrooms would require 24TW, which represents approximately a 10% increase in global power consumption.

Certainly a lot, but doesn't seem "catastrophic" and is realistic with today's technology.

berndi··on H5N1 prevalence in milk suggest US bird flu outbreak in cows is widespread
Do the cows know they are herbivores? Why would the fact that they don’t predate on other animals in the wild make it “abhorrent” to feed them animal products in captivity?
berndi··on Automated Terminal Attack Capability Making Its Way into Ukraine's FPV Drones
TLDR: no evidence is presented for automated terminal attack capabilities. Even a heat-seeking missile is more automated than these drones which simply maintain course.
berndi··on Quantum computers move closer to the assembly line
You’re right! The trapped ion approach (IonQ) is the most promising direction toward scalable quantum computing. Superconducting qubits — such as those used by IBM and Google — require extreme cooling while ions can be trapped at room temperature. Superconducting qubits are also plagued by substrate imperfections, while trapped ions — being “nature’s qubits” — are absolutely identical in their quantum mechanical properties. This allows trapped ion quantum computers to realize the best demonstrated gate fidelities.
berndi··on The race is on to stop Ozempic muscle loss
Is there any evidence that Ozempic causes more muscle loss than what is to be expected from caloric restriction? I haven’t seen any.
berndi··on Telling GPT-4 you're scared or under pressure improves performance
You’re confused about what “statistical parrot” means and you don’t seem to understand the difference between an optimization objective and the resulting model.

The term “parrot” is used to imply inference by something akin to a look-up table, specifically it is used to indicate poor out-of-sample performance and a lack of a proper world model. The optimization objective is irrelevant when determining the generalization performance of a model and when judging whether it can reason beyond looking up answers in a table.

As the user above noted, it is now quite well established that GPT-4 has impressive out-of-sample performance which can be explained by it possessing an actual model of the world and not being a “parrot”.

berndi··on No level of alcohol consumption is safe for our health
The vast majority of people enjoy drinking and do so responsibly.

I absolutely respect people who drink in a measured way to enrich their life, instead of trying to maximize their lifespan by some minuscule amount.

berndi··on Slow Travel
Pretty sure earth will be fine, humans may not be.
berndi··on Ask HN: Europe to East Coast, does it make sense to move at 50?
Thats not even close.
berndi··on 15 of 23 Monkeys with Elon Musk’s Neuralink Brain Chips Reportedly Died
We've been able to get a one- or two-dimensional control signal from average brain activity for a long time. This is infinitely more simple than actual "mind-reading" and "mind-writing" which, as any neuroscientist will tell you, we don't have clue how to do.
berndi··on Adobe tricks users into a 12 month contract
I just used the chat to cancel my subscription and they waived the early-cancellation fee without any issues. Maybe its some sort of damage control.
berndi··on Variational Neural Cellular Automata
Fig. 15 shows results for a single sample, I believe.
berndi··on Germany to admit 400k skilled immigrants annually
You're right, an easy fix for this is to live and work outside of metropolitan areas where you get the same standard of living for a fraction of the cost.
berndi··on German minister asks Google and Apple to remove Telegram from app stores
Free speech is not really a thing in Germany (e.g., until very recently, insulting foreign heads of state was a criminal offence). Our ruling class absolutely resents the fact that the German people may have a channel for at least somewhat uncensored communication. Unfortunately, we don’t have a first amendment that would put some restrictions on their lust for control and power.
berndi··on Please commit more blatant academic fraud
You would think that allegedly driving a PoC student to suicide would count for something in the PC twitter sphere…
berndi··on Please commit more blatant academic fraud
How is it possible that professors with impeccable academic credentials get fired for jokes nearly instantly [1], yet this student's professor was allowed to carry on until he resigned two years later [2]?

berndi··on Please commit more blatant academic fraud
Wow, the amount of depravity in some academic circles is astonishing.

The article links [1] the case of a PhD student at the University of Florida who was forced to participate in such a publication collusion ring and was pressured to commit scientific fraud by fabricating results and submitting them to a conference [2], being threatened with physical harm should he decide to go public.

This student saw no way out and decided to kill himself.

Just a few days after the suicide, the department thought it would be appropriate for the student's own lab to have a "fun" excursion and to document it on Instagram [3].

I'm lost for words.

berndi··on Making the hard problem of consciousness easier
Any reasonable definition of "observing" presupposes a conscious observer and it is possible for you to observe yourself being conscious (I assume). Indeed, consciousness is observable in a much more direct sense than gravity.
berndi··on Making the hard problem of consciousness easier
I'm having a hard time understanding your post -- my depth of thinking may well not be on par with yours. Its obvious that science as a whole explains a hierarchy of phenomenona, with a given phenomenon (like radiation propagation) often being explained ("why does it happen in this specific way") by a more fundamental theory that provides an overarching account of a set of phenomena.

The point is that every update of a scientific theory shifts old "why" questions to new ones. Science will not ever and does not aim to provide an answer to the ultimate question of why anything exists at all or why a given theory of everything applies rather than another (indeed, string theory for example posits a possible, if not actual theory of everything).

In this sense, in the scientific study of consciousness, we do not aim for an ultimate account of why the laws of nature give rise to consciousness. Instead, it is about explaining a natural phenomenon within a theoretical framework that allows us to make predictions with respect to experimental outcomes.

berndi··on Making the hard problem of consciousness easier
I think you are confusing science with philosophy. In science, solving a problem amounts to building a (quantitative) theory that allows us to predict phenomena and outcomes in the real world. We say that we have understood a phenomenon when we have a self-consistent theory that makes predictions validated in experiments.

The ultimate question of "why" reality behaves in a way that is congruent with a given theory is left to philosophers.

Your claim that a theory of consciousness would simply "shift the problem" is only true with respect to these philosophic (arguably unscientific) types of questions.

Consider the problem of gravity. Very coarsely, we have moved from Aristotle's theory of gravity: the natural place of things is on the ground and things like to stay in their natural place, to Newtonian gravity: objects are attracted with a force that is proportional to the product of their masses, to general relativity: objects follow geodesics in curved spacetime, with the curvature determined by the energy content of space.

Our grasp on gravity has certainly improved greatly, but the "why" questions have simply been shifted.

Consciousness is a natural phenomenon and as such can be subject to scientific study. The ultimate question of why the laws of nature are as they are is not part of this project and is best entertained after closing time.

berndi··on Wrigley and others are suing over look-alike THC treats
I'm sad to say its anything but scaremongering.

I don't know about the US, but in Germany its common practice to spray either legal CBD weed or regular weed with synthetic cannabinoids and sell it as "Haze". The same goes for hash.

This practice has been widely publicized and is regularly confirmed through tests (see drug checking websites). A quick Google search will demonstrate the abundant availability of the raw materials (fake hash, legal CBD weed, synthetic cannabinoids, fake packaging). Besides this objective evidence, it is both my personal experience and common knowledge on Germany's streets that laced weed is the norm at this point.

Its obvious that this would happen when there is no regulation but strong financial incentives to produce this crap. Many customers don't care or explicitly look for the much stronger high that these laced products provide.

berndi··on Wrigley and others are suing over look-alike THC treats
You would be lucky if any actual THC is involved, nowadays its mostly synthetic semi-legal cannabinoids in the black market, at least in Germany (apparently even in some coffee shops in the Netherlands). The market desperately needs to be regulated.
berndi··on Bill and Melinda gates divorce after 27 years of marriage
Exactly. How are romantic relationships not a zero-sum game?
berndi··on The Peer-to-Peer Simulation Hypothesis
The author clearly does not have a basic understanding of (quantum) physics, yet makes the bold assertion that his "theory" explains quantum mechanics and relativity. For example, his distributed simulation idea is obviously incompatible with basic results of quantum mechanics [1]. An actual theory would make quantitative predictions beyond drawing heuristic connections in a prosaic wall of text.

Its truly impressive that you can build an academic career in philosophy by producing such content. The days where GPT-4 will advance to a faculty position in this field are probably not that far ahead.

berndi··on Facebook to restore news pages in Australia
Its more like FB decided to go with the nuclear option, Z, instead of X or Y. This is reminiscent of mob-like extortion tactics, not of good-faith engagement with the legislative process of a democracy.

>And the drafters of that law very intentionally made the definition of news content as vague and broad as possible, to maximize the damage and thus minimize the odds of Facebook actually doing it.

Did you get that narrative straight from FB's PR department?

berndi··on Facebook to restore news pages in Australia
The alternative would have been for FB to clarify what you say is opaque about the legislation. The fact that FB would rather outright ban charities and emergency service providers instead of clarifying the spirit of the law shows you that they are not operating in good faith and will maximize their profits at all societal costs.
