This is a classical circular problem of transportation planning: when deciding whether to get a car, and if yes which car, people often use their vacation as a use case. And then, when they got that VW bus to go to the seeside once a year, using it in the city is the logical choice, because it is just lying around. Basically, getting a car is expensive, but once you have it, using it is cheaper (and often faster and more comfortable) than the other options.

So a lot of the discution about getting people "out of cars" is not about getting people to never drive, but to get them to not own a car, such that they have to make the concious decision of renting a car for the holidays, if this is the best choice, for instance. What you describe sound like this.

Obviously, this opens the question of how to improve the car rental market to make those options real options. This is where car-sharing systems and the like come in.

Very interesting. I first wondered how nature can randomly generate such a pattern, and then realized we are just falling for our "built in" pattern recognition: it would feel much more "natural" for the stop sequence to be the encoding of some specific protein without any clearly recognizable pattern... But it would actually be more unlikely to appear/survive mutation than "any long-enough sequence of A".

I also like how it is established that this has an effect on replication, but that as far as I understand we do not understand the underlying process. Humbling.

This was my question as well. I was myself directly involved for about 10 years in the development and maintenance of a medium-sized open source project, and am still part of the community, and there was never really any form of "external contribution", appart from the occasional user who found a problem in the docs or a small bug and was knowledgeable and kind enough to fix it and submit a PR (less than a handful in 10 years). And we typically would already know the guys from conferences or similar.

I feel that the user is coming from a place of wanting to gather experience and show it, and read somewhere that open source is great for this. But lots of projects are open source not to favor external contributions, but for other reasons. And external contributors will typically be long term users of the software, who already have deep knowledge about it and a personal interest in moving it forward.

If the aim is to get experience, I am actually convinced that it is easier to get an entry-level job than to invest the time and effort to be able to make significant contributions to big open source projects. Of course if you manage to get a job where you can contribute to open source, even better.

Good luck!

For anyone interested in those topics, I can really recommend the report of the Galileo commission: https://galileocommission.org/report/

It is a report from a number of established scientists and philosophers, which questions the assumption that science is necessarily materialistic. It is a very thorough summary of centuries of scientific evolution, and of the place of background assumptions, whatever they are.

To be honest, there are 1000 ways to see this work, and he probably had a very different view of what he was doing than "chipping a the same rock for 5 years". Here is a proposal that might be closer to what he was feeling: carefully revealing a creature no eyes saw since millions of year as carefully as if you were unclothing your first love. With each movements, getting more intimate with it, more familiar with every detail of its skin, until you know its features better than your own. For millions of year, it was encased in cold stone, as a fairy tale princess enclosed in a cold room, that you would be preparing for its first night in the world.

I do not mean to diminish the level of discipline and patience required, just to point that the fantasy you have about your work is much more important than the work itself, and that there is a lot of beauty into that task, certainly much more than in creating data pipelines to decide how to better trick unsuspecting web users to click on ads (and there, again, people who do that kind of thing probably have a very different fantasy than mine).

I wanted to say the same thing. Here i Germany the choice of vegan sausage and cold cuts is huge, even in small grocery shops. I know lot of people who eat meat regularly _and_ buy the vegan alternatives on a regular basis.

I would argue the opposite. Give anyone who can write reasonnably the abstract of a few dozen papers in a given field, and I am confident they would be able to produce a convincing bullshit abstract. Most abstracts in a given field sound extremely similar, and are mostly keyword dropping with an ounce of self-promotion. I actually think that the only reason ChatGPT did not produce a higher rate of convincing abstracts is that the reaserchers assessing them knew they had a high probability to look at an AI result and were thus extra careful. Most of the abstracts correctly labelled as AI would probably be considered legit (which does not mean good) if sent to a conference without warning.

I do not live in Switzerland anymore, so I cannot do a survey, but I can tell you helicopters are used an absurd amount in Switzerland, and everyone seems fine with it. For instance I personally saw, with my own eyes, helicopters used to:

- install an AC unit on the roof of a university building

- move building material from one side of campus to the other side

- extract dead trees from a small forest with an extensive network of roads and paths

- plant trees in the middle of campus. Which lead to this fantastic exchange with my then 2 yo: "look papa, a flying tree!" "What do you mean?" "There!" "Oh, you are right. A flying tree. Do you want a banana?"

My pet theory is that given the high wages in Switzerland, it quickly becomes cheaper to rent a chopper for two hours then to get a crane built, operated and unbuilt.

Re looking silly, I am not so sure. Only 10 years ago no one would have expected adults to proudly navigate the city on flashy colored elwctric kick scooters, and yet look at any big (european?) city nowadays. Even investment bankers in tailor-made suits move on those abominations as if it was the next lamborghini.

I actually find them quite attractive as a means to access my local train station: easier to take with me than a bike or kick scooter, apparently much safer than rollerblades or skateboard. Just not for that price, but let's give it a few years to see if it takes on.

Trying to interpret dreams logically is unlikely to generate explanations that are helpful: there are so many possibilities, and even when one finds an explanation that makes sense, one is left wonderingwhat to do with it. A much more potent approach seems to be to re-explore the dream as image, being mindful of the resonances you can feel in the body, and letting it develop the way it wants, without focusing too much on "understanding" or any specific goal. This might sound a bit abstract, but here is a two part blog post which I think explains this pretty well (I am not the author):

(Note: I was quite familiar with "imaginal meditation" when I first found this post, so to me this made a lot of sense and was immediately applicable. But I hope and think that it is even if one is not familiar with those practices)
