Yes, exactly. Since demand for healthcare services is essentially unlimited, creating artificial shortages is one way to ration care and hold down public spending. The US government already creates healthcare shortages in other ways, such as constraining the number of residency slots to limit Medicare spending. (I don't support this, but it is somewhat effective from a fiscal policy perspective.)

Ethics study is rarely about what decision to make, but mostly about how to make a decision. So, there's no problem with teaching ethics in the presence of defense industry.

Similarly, doctors learn medical ethics, and, of course, not every question has the "right" answer. Partially, medical (and research) ethics are about knowing what constitutes malpractice under current law, but it's also about some more general ideas (on which the law might be based) that are hard to quantify. Here's one example: during a drug research, if the interim results show that the newly suggested treatment is unambiguously better than the one given to the control group, the researcher is compelled to stop the research and just move everyone to the new drug. But, the reality is rarely so clear-cut. The researcher might not be confident in the accuracy of the intermediate results. While the average success from a particular treatment might improve, it might also worsen the situation for some outliers in the target group etc. All this would lead the researcher to the situation where they need to select between continuing and stopping the research with no clear best choice.
Seems trivially easy to hit their evade scenario though.

The Kindle's light comes from a ring of linear LEDs that goes through a plastic sheet called a diffuser -- same as the light from an iPad. In the iPad the diffuser is behind the image whereas in the Kindle, it is in front of it, but why is that better or "more diffuse"?

>much closer to just having a reading light on

First of all, that contradicts the evidence from my eyes, but second of all, even if it were true, you'd have to persuade me that reading an old-fashion paper book with a reading light is any better at helping me get to sleep at night than reading from an iPad. I'm not buying that one either mainly because a reading light is going to throw more light onto the ceiling, where of course it gets reflected down again, and neuroscientists know (and the Scandinavian tradition "knew" in practice decades ago) that light from the top of the field of vision is more disruptive to sleep than light coming straight into the eye or from the sides or bottom of the visual field.

>For me it seemed like more effort to skim than HN but I am not sure why that is.

For me it's the length of the headlines. HN headlines tend to be 10-12 words max. Headlines on this site are 3-4 times longer, and are significantly harder to parse (for me at least). The headlines on the actual article look to be more concise. For example, the first link right now is "At least 16 people, including the mayor of Nabatieh, Lebanon, are killed in an Israeli Air Force airstrike on a municipal building in Nabatieh, with Lebanese Prime Minister Najib Mikati condemning the attack. (BBC News)" and when you click it you see the much more concise "Mayor and 15 others killed in Israeli strike on Lebanon council meeting". If it's trying to be a 1-sentence summary of the article, instead of a headline, I don't find that very helpful.

>There's plenty of fleet sources claiming vans are already winning on TCO in europe.

Can you cite one? All I'm finding is SEO/AI/low effort listicle type garbage.

>Which makes sense. Like city busses, EV vans in last mile city traffic are the low hanging fruit for EV adoption.

If it makes so much sense for so many users then why aren't we seeing more than the slightest trickle of the?

There's a reason I called the E-transit a joke. That's because it is. Low milage "go somewhere and stay there all day" type van buyers won't pay the initial price. The people moving users who generally buy the higher priced stuff new rack up too many miles in a day and they're gonna suffer some of the worst real world range because they have to heat and cool the cargo.

The only bigger work vehicle EVs are really starting to make sense for is city busses and local delivery (e.g. Amazon and similiar) that need low range, low flexibility (can't turn a van around and send it back out with a new driver at end of shift) and high up front cost. That's a tiny slice of users.

I really want this to work (especially for motor coaches for obvious NVH reasons) because EVs when they work they do an amazing job being pure appliance vehicles. But it just doesn't pencil out without using mental tricks or just writing off downsides that need to be planned around because "other people's money".
> 99% of the same old things ... tyres, brakes

Aren't brakes one shared system where electric vehicles have an advantage? With the widespread use of regenerative braking, most of the energy of motion is bled off without friction on wear parts. EVs still need brake discs and calipers to maintain a full stop (particularly on an incline), for emergency braking, and as a failsafe, but the parts should experience much less routine wear.

Additionally, your list omits the entire exhaust system, which is full of components that can foul up or corrode. Combustion exhaust gasses can be pretty corrosive stuff, particularly when combined with water condensation on short trips/cold days.

A concurrent optimization of stable reproduction (and nothing more) modulated by natural+emergent logistic maps.

Personally, and in hindsight ofc, I find abiogenesis much more miraculous than the life/evolution following it, cause the latter was sort of obvious and almost indestructible by its nature after it all started. It sort of just happens unamazingly in the complexity space it is lazily exploring (which itself is amazing that it exists).

Only intelligent agents can explore it with a goal different from (but still including) stable reproduction.

No, it used to be the case that there were architectures where signed integers were represented as 1s complement, so portable code could not rely on signed integer overflow wrapping around (there would either be 2 bit patterns representing zero, or sometimes the all-ones pattern had special meaning, like a trap).

Using this type of UB is a "relatively" new thing (GCC started doing it in the 00s, which broke a lot of stuff in the Linux world, IIRC).

It _is_ true that somebody did the research (can't find the source right now) and found that defining signed integer overflow as wrapping did indeed make some code run slower. I'm skeptical that it matters.

It is a useful feature. We’ve had tons and tons of bugs caused by C/C++ misfeatures which is both why Rust was invented and why users are looking for more stable alternatives after decades on the patch of the week treadmill. A tool like this is aimed at a technical audience who will see the appeal of a tool which is safer and easier to work on.

There are many examples of successful companies that fall into that category.

Sometimes an innovation needs critical mass to work - social networks for example. LinkedIn famously got big by being extremely aggressive on how they mined your contacts. You'd get sued to the moon and back in the EU for this behaviour.

LinkedIn is big now, it has established itself and no longer needs to be that aggressive. Any European player that tried to enter the market with a less aggressive stance had no chance - they never reached that critical mass.

The website states: "OpenVMM is a modular, cross-platform, general-purpose Virtual Machine Monitor (VMM), written in Rust."

I'd leave out the "written in Rust", because who cares, but I think it's in the license terms for Rust that you need to include that in when communication your project. The modular and cross-platform is much more interesting that the implementation language, and much more relevant for the majority of the users. I'd focus on that if I wrote the documentation and marketing material. One excuse I'd make is that the link is to the Github repository, where it's perhaps more relevant that you're informed that you'll be looking at Rust code.

I believe that low power = cheaper tokens = more affordable and sustainable, to me this is what a consumer will benefit from overall. Power hungry GPUs seem to sit better in research, commerce, and enterprise.

The Nvidia killer would be chips and memory that are affordable enough to run a good enough model on a personal device, like a smartphone.

I think the future of this tech, if the general populace buys into LLMs being useful enough to pay a small premium for the device, is personal models that by their nature provide privacy. The amount of personal information folks unload on ChatGPT and the like is astounding. AI virtual girlfriend apps frequently get fed the most darkest kinks, vulnerable admissions, and maybe even incriminating conversations, according to Redditors that are addicted to these things. This is all given away to no-name companies that stand up apps on the app store.

Google even states that if you turn Gemini history on then they will be able to review anything you talk about.

For complex token prediction that requires a bigger model the personal could switch to consulting a cloud LLM, but privacy really needs to be ensured for consumers.

I don't believe we need cutting edge reasoning, or party trick LLMs for day to day personal assistance, chat, or information discovery.

> weak ethical discussion

followed by a one clause stone-throw. Irony?

So, the major democracies are imperialist powers? Do you live in a small dictatorship? If not, to be consistent with the rock you just threw, you don't pay your taxes? Do you just not take responsibility for anything? Because that's what he's arguing Palantir does.

Here's another take: since WW2 there's been a messy but semi-stable competition between the great powers expressed most visibly through a series of proxy wars near the perimeter of Russia and China. However, the competition is also expressed in the global economy, on the networks, in space, in the oceans. Turns out good people are often forced into ethically tenuous situations and in a world with 8 billion people, every one of whom has lots of opinions, there's a lot of possibility for entirely reasonable people to find themselves in life-and-death struggles.

Wolf packs defend their resources, mainly by marking their territorial boundaries but occasionally they fight. Are they unethical in doing so? Are we any different?

> However, witnessing the rapid evolution of AI with just a few hundred GPUs, enough data, and power, I no longer wonder what a billion years of feedback loops and randomness can achieve.

The thing with evolution is that it is robust. Even after the human species collapses (with everything it manages to bring down with it), evolution will still work.

Modern humans have been very quick at many things, but at the cost of breaking the conditions of their survival. One may say "that's wrong, with enough GPU a solution will appear", but on the other hand maybe we have already passed the tipping point where we actually cannot solve it anymore.

Just so we're clear, yes, it's "hardware-dependent", but literally every single architecture and CPU model does the same reasonable thing, which is to wrap into the negative.

Any architecture that doesn't use 2s complement is so esoteric by now that it does not make any sense for a general-purpose C compiler to pretend they exist.
The speed of light in vacuum is constant and is not impacted by gravity, AFAIK. Really the light is travelling in a straight line in space but gravity bends space and time.

Yes, the planet (hypothetically, a very earth-like planet with a 1-year, 1 AU orbit, 24-hour rotation, and 23-degree tilt at 4 light years' distance like Proxima Centauri b) moves at most 2 AU in a 6 month integration, and the telescope ~700 AU behind the center of the lens would have to move more to keep it opposed. But that 4 light year distance means it's 250,000 AU from the Sun, so some basic geometry says it only has to translate laterally by on the order of 2 * 700 / 250,000 = 0.0056 AU. You're right that that is far larger than an image sensor would be, and larger than the solar sails that would push this craft would be, but inconsequential for a vehicle that's just flown 700 AU.

Planets not only move relative to their star, but they also rotate and tilt. I see a number of artists' depictions of the planet (eg at [1]) that look like the satellite just flew into space, illuminated a circular planet with a giant flash bulb, and returned a pixellated photo. I've only thought about this for a minute, but I don't think it would look anything like that.

Trying to integrate an image of over the course of a 6-month exposure means not only tracking where the planet is in its orbit but also discerning the longitude on the planet from which a given photon was emitted at a particular time. Plus, if it's tilted at all, we might get many images of the north pole and none of the south pole, or an underexposed image of some polar regions that were only aligned with us for a small duration of the exposure. Finally, even though this gravitational lens is enormous and can collect many more light rays that happen to be aimed at the sun on the image sensor than a physical lens or mirror could, light still has to come from somewhere - specifically, the host star, so only half of the sphere can potentially receive photons that might bounce in our direction at any time, and that half may or may not be aligned with us. Finally, over the course of 6 months, the planet might experience seasons, with changes in the atmosphere and surface ice!

Assembling the raw data into a sharp image would be far more challenging than just opening and closing a shutter then grabbing a serial stream of X by Y pixel data from an image sensor, but the output might be much more than a single image.
