>GHG are a matter of life or death

That's what I hear from mainstream media all the time. Do you have some information or argument that will help me see things differently?

>Of course you live in a 1st world country and it likely won't kill you, just cost you tons of money

A little presumptuous to assume my living conditions

>It's not about "take better care of the planet", whatever you think that means

Now that's just snarky and done in bad faith. If I didn't care would I have posted it, already antecipating the downvotes?

We humans got where we are much due to technology, but we have to start thinking seriously where we go from here or there won't be land or water (or air?) that isn't polluted by something the planet is not well equiped to process. Have you read on the kind of places that microplastics have been found already? In the human body?

I already told you 2 things, coastal areas and agriculture.

This is Bangladesh elevation map. Bangladesh is amonng the most dense countries in the world, and also among the poorest.

People are gonna lose their homes and starve to death, this will create massive refugee crises. They won't care if you have micro plastics in your testicles

Because this is HN, (in Allo Allo's Michelle Dubois voice...) "I shall say this only wonce": If you're curious, have a look at Earth's historical temperature and co2 data going back millions of years. What you'll notice is that there's always been oscillations, like a more or less predictable wave. Human activity is polluting the Earth, yes, but this fixation on co2 and other gases (cow farts, really?) is unhealthy to put it mildly.

I'd like to see the same attention being given to plastics (so much single-use crap and how much of it can be recycled?), synthetic clothing, and all kinds of other chemicals including the ones we put in ourselves (pharma, food) and the environment, like fertilizers or the byproducts of mining today's fashionable minerals like lithium. Not to mention the explosion in electromagnetic frequencies activity, which somehow is taken as normal and ok by the same scientific establishment which accepts thousands(?) of fake papers every year for publication. You just have to love the irony when something like Science is deemed 'settled'-- in that regard, it's almost as if we went back a few centuries.

There's certainly a lot to be said for humans needing to take better care of the planet. Co2 just gets a little too much attention for my taste. And don't take from this that I love oil. I find fracking to be abominable and another big factor in polluting the land and the water tables.

GHG are a matter of life or death for hundreds of millions living in poverty in coastal areas or living from their own agriculture.

Of course you live in a 1st world country and it likely won't kill you, just cost you tons of money

It's not about "take better care of the planet", whatever you think that means

This is Big Oil propaganda. The impact from this is massively less than the horrific damage caused by every part of the fossil fuel industry.

Yep. It's not just oil rigs in the desert. Chevron in Ecuador destroyed the Amazonian rainforest. Oil pipelines and open pit mines destroying Canadian primordial forests. Probably tons of untold stories.
mrpopo commented on How to store a chess position in 26 bytes (2022)   ezzeriesa.notion.site/How... · Posted by u/kurinikku

I remember asking myself this question years ago, and came to 162 bits. I was just a kid back then so the logic is probably wrong but I do wonder how simple the encoding could be under those constraints...

Edit: Here are the Notes

0 Empty

10 Pawn

1100 Knight

1101 Rook

1110 Bishop

1111 Queen

32 + 32 + 472

2 times 6 bits: position of the kings

30 bits: color mask

120 + 2*6 + 30 = 162 bits

We can store the rest using the methods from the blog post and add 18 bits for promotion, giving 180 bits.

I'm sure this isn't the most efficient way, and I think I had other methods and considered things like the bishops being able to occupy 32 squares, though special casing doesn't make sense because of promotions.

Technically if you got 8 bishops/queens/knights/rooks You would occupy another 16 bits, giving 196 bits

I think the upper limit can be reduced at the cost of increasing the lower limit

EDIT2: I think I made the assumption at the time that to promote one piece you needed to capture at least one enemy pawn, giving the space for the two bits, which means the upper bound is actually 180 bits

Would love to see other people try in the comment section

mrpopo · a month ago
Considering at least half of all squares are empty, further compression is in order for the empty space.

Also if you're encoding the king as a position instead of a byte sequence you would have to encode their space as empty, that's an extra 2 bits

Yes, US rail is pathetic, at least for passenger travel. However, a quick search on Google Flights shows a one-way ticket from LA to DC costs $98.00 on Frontier via Atlanta (YMMV) so I don't think it's correct to say there isn't cheap, easy, high speed travel across the country.

It's also 700kg of CO2, one of the best ways to worsen climate change per dollar spent

Most people don't want trains. Most places where people want trains have them (high density places).
mrpopo · 5 months ago
Trains are just the most efficient way of moving people between cities. They benefit everyone, even people with cars.

You have a business trip and need to go from A to B by yourself? Take a train, it frees your brain and the highway for people traveling in groups or with lots of luggage.

Incidentally it also avoids moving 2 tonnes of material for no reason.

mrpopo commented on Microsoft subtracts C/C++ extension from VS Code forks   theregister.com/2025/04/2... · Posted by u/Dotnaught

I think your analogies are wrong.

There is a direct cost to Microsoft that these companies are pushing on them. Specifically around bandwidth.

Microsoft does not need to provide access for downloading plugins from their servers to anyone else.

mrpopo · 10 months ago
I am quite confident that the bandwidth cost is absolutely not a concern for Microsoft, and that the obvious goal is for them to capture the market.

The "C/C++" extension github repository is 4MB. Probably the download size for the extension itself is a fraction of that, but I won't bother measuring. It was downloaded 400 times over the last minute (there is a live counter on the extension page [0]).

[0] https://marketplace.visualstudio.com/items?itemName=ms-vscod...

That's a 25MB/s or 200Mb/s bandwidth, for one of the most popular extensions. Multiply by the top 10 extensions and you get the bandwidth of an average home optic fiber connection...

How large a scale and with how many countries participating would cloud seeding be able to reverse these effects? Last I remember it was only a few countries in Asia that were attempting anything of the sort.
mrpopo · 10 months ago
Disregard the obvious environmental risks of spraying silver iodide in the air, cloud seeding will artificially redirect rainfall in specific areas, which may deprive downstream regions of water, harming biodiversity. Note that cloud seeding is currently used for drought management, not global warming mitigation.

They also have 2% ev marketshare in China, because its still an expensive and complex feature that has downsides that the previous comment mentioned. Like these high energy batteries are dangerous as the can burn quite spectacularly, so I personally would not want to take and remove one from my car every charge hen I can wait a few minutes at a regular charging station that is much more common than a replacing station.
mrpopo · a year ago
I don't think a battery swap is more dangerous than the current fuel stations where you can just use your lighter and set everything on fire
