Animal models are definitely inaccurate in general. But memory mechanisms are conserved and it's also false to believe that our brain's intuitions are true. We have blind spots left and right, a false sense of free will and a long history of inaccurate memories.

That is actually what taxation-based solutions do. They make travel cost more, so fewer people do it.
Let me take a shot at answering this.
The idea is that the internet is a social construct. The information it holds is shared knowledge accessible to everyone.

Contrast burning your photos with burning all copies of a book. On the internet, a lot of things exist in the gray area between them.

That makes it difficult to judge if the info that was is private or public.

"At present there are no proven technologies capable of large-scale air capture of CO2. It has been suggested that, with strong research and development support and industrial scale pilot projects sustained over decades, costs as low as ∼$500/tC may be achievable [226]. Thermodynamic constraints [227] suggest that this cost estimate may be low. An assessment by the American Physical Society [228] argues that the lowest currently achievable cost, using existing approaches, is much greater ($600/tCO2 or $2200/tC)."

So that's $600+ for an NY-SF round trip - in decades time. Currently we would have no flights at all.

I've noticed Waze optimizing for quickness. Not fastest, not shortest, not most direct but the route which makes you feel like you are getting there quicker. Often longer stretches with no traffic or junctions for example.

It's as if users main priority is not to be held up. Users don't care if the journey is two minutes longer or a few pence more expensive, they just don't want to be feeling they are making no progress.
Most of this research is actually driven (and funded) by the desire to identify and erase memories for e.g. PTSD victims. It doesn't require "rewriting", there are ways to delete engrams with chemical inactivation for example.

Indeed. It is important to pursue research even if there is no immediate benefit from it. In this case it is even touching on a gateway technology I would call marvellous. Stable high temperature superconductor material would change so much.
Clever Hans couldn't answer the simplest of questions if the asker didn't already know the answer. If we were all Clever Hans, there'd be nobody left to feed us answers.

> The main difference between Waze and Google Maps is that Waze uses real time traffic data.

Google Maps has real time traffic data and the accuracy is staggering. I occasionally use Google Maps for navigation in the car and it even highlights traffic stationary at traffic lights and temporary road works as I’m approaching.

This level or real time detail really amazed me. I’ve not spent any time looking onto how they do it but assume they are continually tracking everyone with a phone, or at least running Google Maps Navigation, and using their real time location and speed.
It seems like by adding parent pointer one is shifting complexity from the traversal into the data structure, in order to avoid a stack. I know there are places where avoiding an explicit stack can be nice (perhaps a BVH tree in a shader or other places where constant space is required?) but are there more good reasons for it?
A DAG (such as a singly linked tree) has so many benefits for memory safety, GC performance, ability to extend it from a binary tree to N children etc., that it seems like an odd tradeoff in most scenarios.
Godwin point reached.
I was confused by that as well before reading the answers: the confusion stemmed from only thinking about the linear traversal or search use cases, where an ordered array plus binary search is all you'd ever need for reading. But when the tree shape itself is still needed, indices can be better than pointers, particularly when adding sidecar arrays for extension or as temporary scribble space (see sibling comment).

>While still billions of people believe in Allah, God or whatever without any evidence. I dont know how this can happen...

Isn't it obvious? In both cases people do the smart thing (which is not necessarily the "objectively correct" thing).

Faith in Allah, God etc, is a good social glue, and is personally comforting, helping regulate emotions, etc.

Similarly, not believing the Snowden story helps them fit with their social group (e.g. republicans), relaxes their mind from a whole lot of worries and concerns, helps re-enforce their personal beliefs (e.g. in good government), etc -- and most importantly, has no real disadvantage in their day to day life and work...

Agreed on the intel community generally being in a grey area as far as the law is concerned, it's a struggle enough keeping them impartial and not meddling in domestic affairs - talking about JZ being head of the ANC's intelligence in exile brings back memories of his ultimate succession of Thabo Mbeki and former spy chief Billy Masetlha's role in that.

On the same (wrong) line of thinking we can't say humans can walk because some of them can't.

Not all birds fly as well...

besides, some animals are better than others for testing purpose.

Mice are well known for having a great memory, testing mice for memory makes sense.

Recent studies proved that mice memory cells work on experiences and not on places, just like ours.

> there is not a single 'objective' truth but multiple often contradictory truths

This is something that's usually said by people who want you to drop your defenses and believe in lies they concocted.

To the best of my knowledge, there's nothing we've seen so far that would suggest we aren't all inhabiting the same, shared, physical universe - so there is objective truth. There are facts about the world around us, and when you're reporting them accurately, you're reporting the truth. If you deny those facts, you are reporting falsehoods.

Now one of those facts is that we all observe the world through a limited and biased sensory and cognitive apparatus. We can't perceive the entirety of the universe, only a small fraction of it. This sometimes leads to "contradictory truths".

The best analogy I've come up with so far is projections. Imagine the universe as a 3D space, and anything of interest as a 3D shape - but what each of us is observing is 2D projections of it. So there is a cylinder in that universe, representing an issue. I can claim the issue is circular. You can claim the issue is rectangular. We've both identified the true aspects of an issue, but our views are incomplete. Our views combined can help us understand the full form of the issue. But what's most important, if someone comes in and says they see a spiked star, they're just wrong. There's no "multiple often contradictory truths here".

This is the way I like to think about the world and debates on issues. Each of us operates on a set of facts and intuitions that are a result of a heavy dimensionality reduction. We operate on projections. But there is an objective reality, of which our conflicting views are different projections, and that reality makes it so that only some projections are valid, and others are wrong.

And just because an issue is primarily social doesn't mean it's magically not about the observable reality. Human beings are physical, material objects. Just damn complicated ones.
You're right, I should have said "on X11/Wayland DEs".
> a very large part of its identity is derived from memory and/or common history

There is vast literature about how this identity is partially built on collective false myths and the desire to collectively forget inconvenient facts. Our public identities are largely defined by our willingless to tell white lies to each other.

There were not many regulations on international transport as long as you had a decently forged passport. Additionally, there was a lot of support from e.g. church networks that helped out fleeing Nazis. Even the Mossad has its limits.

Slight Tangent: I've got a feeling that private vehicles in Zone 1 (and 2...) benefit a tiny percentage of the population, and should be the next target for reducing inner city congestion (implementation perhaps tricky).

If not, any ideas for what is next? I hope to see:

2. Entire high streets converted to pedestrian, bus & bike only.

3. A move to a more bike/bus friendly city, see Utrecht [1]

A DC fridge does not "solve the problem". The problem the author solved was not having to use a battery to keep the fridge cold at night or when it rains. He did this with a thermal mass (a large tank of water in the fridge) that takes a while to heat up. Kind of like using an ice pack in a cooler box.

I'm assuming that he used an AC fridge / freezer with an inverter because he already had one. Besides, I've never seen a large inexpensive DC fridge before. They just don't enjoy the same economies of scale.

> looking for solutions that require lifestyle changes

Some of these solutions have small to large social impacts in part of the population (see bans on older diesel cars, for example), especially the one that is not too well off (not necessarily poor, let's say lower middle class).

One might want to implement them anyway, but the way I see it, is that some proponents act as if consequences won't exist. They need to be taken into account.
Fun fact: Sonic 3 for Sega Megadrive/Genesis used FeRAM as save RAM. Generally, a Ramtron FM1208S-200CC. I think a few other carts of theirs used it, I've seen 32X Virtua Racing carts with Ramtron FeRAM parts.
Of course this is the long term solution, but replacing all refrigerators in operation, even the ones just manufactured is a total environmental waste compared with getting efficient inverters for solar panels!

Ask HN: I am going into autopilot mode What do I do?
This may sound strange, but I have been going into autopilot mode quite frequently in recent months. What do I mean by "I am going in autopilot mode"? Well, I a software engineer. While thinking about a software solution to a problem, I struggle to come up with a solution and then all of a sudden "I" solve the problem without "me" realising how "I" reached at that solution! This has happend so many times that I thought I would ask here, how do I get out of this "autopilot mode"?
Assuming you genuinely are trying to make a good faith argument (which I strongly feel you're not):

Pandas eat bamboo. Bamboo has practically no nutritional value so, no, Pandas are not very energetic.

None of the vegetarians I know need 16 hours of sleep per day, and I suspect that's because

- They are not bears, and so do not have the metabolism of bears.

- They don't subsist entirely off bamboo, or one foodstuff in general.

Besides, the a primarily vegetarian diet doesn't necessarily mean no meat, it just means realising that meat production is so absurdly energy, land, and water intensive that eating it on a daily basis is simply unsustainable.

The amount of energy that goes into cooking hour meat is negligible compared to the amount of energy needed to produce it in the first place.
> Primarily vegetarian diets and less driving would make mountains of difference for the world.

Changing diets yes. Changing driving habits, not really. Personal use of passenger vehicles accounts for a tiny fraction of transportation related CO2 emissions. The overwhelming majority comes from cargo ships and associated logistics.

A typical cargo ship will burn about 30 liters of bunker fuel (far more polluting than diesel) to travel 1 meter. 15 typical cargo ships emit as much CO2 as all cars on the planet combined. There are about 15,000 such ships operating today, with a further 30,000 slightly smaller ones. A single cruise ship company like Carnival Cruise emits more CO2 than all of Europe's car's combined.

Even if the entire world converted to zero-emission EVs overnight, it wouldn't make a meaningful dent in these numbers.

The inconvenient truth is that in order to make a serious dent on transportation related CO2 emissions, the entire developed world would have to give up its lavish lifestyle of internationally shipped products and foods. Sadly a harder sell then 'drive an EV to save the planet lol', so our governments continue to focus on inconsequential but easily attainable measures. And that is nothing to say of the fact that cutting down international shipping is at odds with free market capitalism that's driving our civilisation.

Fun fact: bulk carrier shipping is so cheap that in Australia, locally caught fish are shipped to China for processing and freezing and then shipped back here for retail. The pollution associated with this alone is more than the sum pollution of all Australian cars.

All of your examples look like one issue to me, which is people unwilling to change their lifestyle and sacrifice their luxuries.

The only way out of this mess is to use less resources, which means consume less, travel less, have fewer children, etc. Carbon tax or dictatorial orders, the root of the problem is people don’t want to consume less, and our children and their children will pay the price due to us not wanting to pay it now.

> Look at pandas

Look at Indians instead. We eat a primarily vegetarian diet. I assure you we sleep nowhere close to 16 hours a day. We also work in the sweltering heat etc, which our diet seems more than capable of taking on.

Yeah, eating raw food is great, and eating less is also great. "Eat food, not too much, mostly plants" and all that, but Indian cuisine stands as an example that eating vegetarian food need not be a bland affair.
Tetris Randomizers (2018)
Next to everyone doing things - we could also add some regulation for extremely polluting industries/companies.

Like I remember that one European Cruise company's ships produced the same amount of CO2-equivalent than all European Cars combined last year (or was it the year before that?).

All friggin EU cars? This is what I would call a lever.

And for what? For the sake of one company making money by providing a kind of recreation that could at least be discussed as it provides recreation - but recreation could be provided in a more environmental friendly way as well.

Just regulating this one industry would go a long way. And there are probably some other low hanging fruits still undiscussed.

Sadly the whole discussion seems to revolve around what the individual should/could do. Often it seems to me especially to mask the fact that regulating some industries would be a faster and imho more efficient way.
The benefits of industrialisation and capitalism have been tremendous for people’s quality of life, stability of their food supply, access to medicine, work hours, work conditions.

While it's true that workers have better and easier lives now than they have had in the past, I don't believe many early entrepreneurs pushed for industrialization for the societal benefits. They did it because those changes made them massive great piles of cash. If your workers are healthier, better educated, and don't hate going to work so much the business benefits far more than the workers do individually.

Better conditions, health, etc are a side effect of industrialization. They were never the goal.

When you see HR making out something is a benefit for the workers you can be fairly sure the management bought in because it will also improve the bottom line in some measurable way.
