There has been progress within the theory of non equilibrium thermodynamics which hint that local entropy decrease is baked into the physics. That is to say life just kind of falls out of the physics of thermodynamic systems of a certain type. That certain type being anything that dissipates a source of energy. Personally I think abiogenesis is relatively easy and there is large scale panspermia going on. The universe is like a yoghurt, bacteria everywhere and novel abiogenic origins occurring all over the place, although there are probably dominant kinds of life. DNA based being one.
Yes, this has been investigated before - e.g.

But the evidence we have (as per prior comments) is that a human-level intelligence civilisation has arisen only once on Earth.
No sacrifice should be required. Let's suppose that we adopt a carbon tax with dividend, along with a carbon tariff.

Estimates for the externalities caused by carbon emissions vary widely, but a median estimate is around $100 / metric tonne, so we'll pick that. Gas prices double. Beef, cement and the usual suspects go up in price substantially, although likely gas is the only thing that doubles. Every family gets a cheque in the mail every month for a few hundred dollars (the dividend).

The carbon tariff means that imports from non-cooperating nations go up in price substantially, but imports from nations that have their own carbon taxes or equivalent are not impacted.

What dramatic sacrifices have you made? Normal families will be able to pay their share of the carbon tax with the dividend.
Ask HN: Best practices for open sourcing your project?
Hi all,

I've been working on https://algodaily.com for the better part of a year now, and would like to open source both the curriculum and platform.

Aside from taking the current spaghetti code and beautifying it, are there any suggested practices for opening up a formerly private repository? I'm wondering about things like secrets management, ads (I have ads on the hosted site, should I remove them from the public repo?), how much documentation to write before shipping, etc.

Appreciate any advice!

Would a novice to the language implement a highly concurrent HTTP service as their first ever task? I don't think so, most people start with "Hello world" programs.

To understand the entirety of that first signature you need to grasp is:

1. The Result type, which returns the result of a successful computation or an error.

2. The Box container, which is basically just a safe pointer to some memory

3. Rust's way of doing polymorphism.

These are indeed some complex topics but I doubt most people start at that level. Sure, an absolute beginner would be dumbfounded by this, but working through even the first few chapters of the Rust book gives you enough knowledge of Result and Box to let you figure out what is going on.

Yes, this is true. O&G companies have so much time, money, and engineering invested, it'd be like asking Google, Twitter, and Facebook to give up their monopolies. It may take time, but scrappy upstarts, better batteries, and Gen4 nuclear will eventually unseat them.

Let's be kind to O&G industries that employ and support the livelihood of billions and have helped advance civilization more than any other industry. Their time is coming for disruption - the timeframe is at least a generation.
Well, 20% of the population (e.g. US and Western Europe say) has the 80% of environmental impact. Including e.g. Chinese factories population etc (most of the production there is for western consumers anyway).

And even 200% the current population could have 10% the current carbon impact (with the appropriate lifestyle adjustments, e.g. green energy, much less consumption, less planned obsolesce, less meat, less greedy corporatism, less international travel, etc.).

So, no, population is not really the problem at the moment (besides it's declining anyway).

I agree - and with this kind of stuff, somehow we're prone to looking at the government like it's a perfectly running black box, with an all-reaching, all-encompassing power and control over information. But if you look at these pieces of information that have gone out - "something is being reported by our people, we don't actually know what is it, people are talking about it to the outside as well, we thought we add some equipment to see if we can find out more" - it seems much more realistic to me, and much more in line with inefficient, clumsy and sometimes incompetent government that it is...
I drive an electric; wife drives a gas ICE; I maintain both. No way is electric brake wear 1% or less of a conventional car (what it would take for it to round down to zero in that table). I'd put it at around 5-10% of an ICE, making the total particulate emissions higher.

I've read that the oceans end up absorbing majority of the CO2 emitted, if that's the case, I haven't seen anything (to my knowledge) that goes towards accelerating this in a sustained way for the marine ecosystem.

The oceans are far larger and I suspect will have less issues with rolling out methods of coping with CO2 i.e won't disrupt jobs or or ways of life.

Does it make sense to attack the problem that way? It has the potential to scale much more quickly. Is there a company attacking this sorts of issues like SolarCity?

This makes sense to a certain degree, but "just ignoring it" only goes so far: even seeing it is corrosive to a certain extent, and by the time you've even registered it enough to ignore it, a lot of the damage is done.

Perfectionists undergo a similar phenomenon, I'm told. After all, the modern "Do it badly" movement was itself a response to the corrosive effect of the "'Good enough' isn't" message permeating all of society. I'm not unsympathetic. In solving one problem, it didn't exactly create another -we've always had perfectionists to some extent- but it made that problem much, much worse than it had once been. But the fact is, it was done to solve a real problem in its own right, and that problem has not gone away.

What it comes down to is conflicting needs. The all-pervasive "'Good enough' isn't" came about because some people genuinely need it, and they genuinely need it at that level. The same is true of the now-pervasive "Do it badly": it is genuinely needed, and at this level. And you can't balance them, because they inherently undermine each other. So what do you do?

I loved Chef after we got familiar with it. It was nice, cute, had solutions for a lot of problems. (foodcritic, kitchen, rubocop, etc.)

But it simply is a solution in search of a problem in today's container orchestrator/platform world.

HAproxy is amazing, but a k8s Ingress service [0] has a nice API, so I don't have to run Chef to add a new vhost. Yet I can persist the config in a YAML. (Or json, or whatever.)

I'm not sure if this is what you were suggesting, but there seems to be some misconception that vegetarians don't like meat.

I like meat, in fact I love it. I used to contribute to a food blog reviewing steak restaurants. I love the smell and (the thought of) the taste. I haven't eaten meat for about five years because of environmental reasons, not because I dislike it.

Not eating meat is such an easy thing for most people to do, the facts are in front of us and it would make a significant difference. It does not fill with me with optimism that most are unwilling to do even this.
Thanks for that list. There is so much data locked up in databases that could benefit from being turned into an API. To say nothing of CSVs and PDFs.

Don't plants require carbon dioxide to grow? I am not sure it was immediately obvious to people 120 years ago (the Mariner 2 spacecraft, which flew past Venus in 1962, was the first to take detailed pictures showing its heat-trapping clouds) that CO2 was such a "dangerous" thing.

I have recently been made aware of relatively inexpensive massive high density tree planting projects as a way to potentially solve the CO2 "problem"[0] I personally find ideas such as these are far better for world's ultra-poor then raising the price of energy thru carbon taxes, as pretty much the only way people can move into a significantly better living situation is thru the use of energy.

In line with the "release early, release often" mantra, you can just go ahead and do it.

Secrets are usually split into separate "configuration" repositories that remain private, and that's the only gotcha.

Any other time you invest in beautifying your code, writing documentation, stripping ads and making them configurable, might be in vein: most open source projects do not attract any contributors, yet having these "easy pickings" is also stimulating for someone to contribute.

Your users are better served having an ability to tinker with the code than waiting for the code to become nicer. At least, the free software persona in me says so :)

Of the ~100 genus (around 3500 species) of mosquitos, only a fraction bite humans and only 3 genus are responsible for most disease spread: Aedes mosquitoes (yellow fever, dengue, and encephalitis), Anopheles mosquitoes (malaria, filariasis, elephantiasis), and Culex mosquitoes (encephalitis, filariasis, West Nile virus). All of these are invasive species to much of the world, they're only there because they were brought in by humans in the first place just like other invasives, and often fairly recently. Their spread has been further heavily facilitated by human altered environments, not just in the big picture like global warming but also more standing water, disruption of predators, and so on.

And the death toll is actually quite remarkable, around 700,000 people a year die directly due to mosquito transmitted diseases.

> the problem is the vested interests.

There is also vested interest at the nation state level. No nation wants to be the only nation to do something serious about climate change. If they were, they would take all the downside, and get none of the benefit.

Some countries are already seeing this. The UK is leading on some emissions control measures, and it's already contributed to bankruptcy of large chunks of it's steel industry.

"And what about Europe? Probably too cold in most of the continent, but present in Mediterranean regions?"

As with other areas they live in or near garbage areas, but as far as I can tell not as common as one could think. I don't recall seeing any for example during garbage collecting emergencies.
They could be present in homes though, especially old ones where small cracks in concrete or wood can offer a place to hide. That was the case of a 4th floor apartment I lived in over 30 years back where we were never able to find the source of those bastards. That wasn't an invasion, just 2 or 3 a week, so we weren't that pressured to call for someone to eradicate them.
The solution came totally unexpected: one day my father brought a cat into that house and from that moment although we keep finding those 2 or 3 cockroaches per week, they were dead. Some time passed by, and one day I found the cat scratching near a baseboard corner; he just found the small crack the roaches used to live in and killed all those coming out of it. We sealed the crack and never saw a cockroach after that.
I moved two times since then, and although my father kept that cat, I soon got two, and besides being wonderful companions, they kill anything entering the house uninvited, including bigger nasty mosquitos.

If the black box is freely floating (which is what I was thinking of), then a particle within it can move to one side only if something else in it moves the other direction.

But on further thought, I wouldn't be surprised if some changes in the internals of the box could produce gravitational waves, so maybe my intuition for this is wrong. Although if I further clarify that the box isn't supposed to be emitting energy (which will obviously reduce its gravitational influence as it loses energy), then maybe the intuition is correct after all...

The interactions inside atoms seem to have no known relations to EM [...]

The electromagnetic and the weak interaction are known to be different aspects of the unified electroweak interaction. There are several grand unified theories and a few hints that at even higher energies the electroweak and strong interaction also unifiy into the electronuclear interaction. Due to the high energies involved, only indirect experimental evidence seems accessable for the forseeable future but there are various groups looking for hints. I am not aware of any uncontroversial results but there are a few non-reproducable experiments, for example observations of magnetic monopoles, which might be due to experimental error but also due to the rarity of magnetic monopoles.
I can imagine this actualy occurring between the low-level employee who spots the snake, and the game of telephone that occurs as the news travels up the command hierarchy to reach someone with authority to do something about it

Which is the tradeoff issue with hierarchies; you want the person at the bottom to be sufficiently autonomous to deal with the problem, as he’ll have the most information about it, but at the same time, its the person at the top who has the global knowledge to determine how it actually effects the rest of the ecosystem. But as the information travels up the chain, it gets (necessarily) aggregated and details are lost
