Sure, for some jobs you will need a car and in that case you bump your prices to match. Since everyone doing this job is hit with the same fee, no one is disadvantaged. While if you work an office job or similar, you can get ahead by not driving and eventually everyone capable of not driving will not drive.

The actual price of fuel does not matter much, only the price you are paying relative to others with the same job title.

I've actually used that whitelist pattern before for legacy software in a non-security context. We had some programs using old stuff, and it was a real hassle to migrate everyone off it due to the massive amount of testing involved. But it was very easy to setup new programs to use something else. The problem was that people just kept calling the old one out of habit.

So I just replaced the executable with a wrapper that checked what is calling it, then called the real one if allowed. I can't remember how but we probably blocked the original executable from general use, but even if we didn't then bypassing this check shows clear intent on the user's part. They can't claim ignorance, which is enough if it shows up in source code later or dies when we finally remove this software. Meanwhile we could move the other users one by one without any new ones sprouting up.

Of course, code reviews, check-in filters, and such might be a nicer solution but this place wasn't that organised. So we did what we could, and didn't really have to keep an active eye out.
They actually are starting to do that:

These are both the same thing.

If I say "I will give you $20 to not drive" or "I will take $20 from you if you drive", the only thing that really matters is that there is a $20 price differential between two actions so you will be at a $20 disadvantage to do the current thing regardless of how you word it.

Money and wealth is relative so the actual final amount doesn't matter as much as how much you have compared to the average person.
I think the reason desalination doesn't make sense is because most of the water is used for agriculture as the comments above mentioned. As such the marginal cost of repurposing water from agriculture to people is probably significantly less than getting that water via desalination.
Citation needed. They seemed pretty reality-based to me.
Other commenters here haven't really provided any good data to show the issue. If you want to run, say, 10A at 24V through DC wire on a circuit you end up needing stupidly thick wire (~6AWG) to avoid voltage drops over just 100ft. There are charts available to show you, for example [1]. If you're thinking of running normal hobby wire for 12V circuits around a house, the resistance losses are going to be huge.

> That would have a particularly large impact on food prices. Increasing the portion of food cost attributable to fuel by between 3x and 10x would hit poorer people particularly hard. It would raise the price of pretty much everything else too, all of which hits people harder the lower they are on the economic ladder.

Yes, the purpose would be to reduce consumption of basically all things, since cheap fossil fuels are the basis of manufacturing and transporting almost all things. Hitting people hard would be a necessary effect of reducing carbon emissions, although wealth transfers from the rich to poor via taxation can modulate how much the poor are hit relative to the rich.
What does SEV mean? Googling didn’t turn up anything.
IMO, this is still a free market modulo the part with the city planning which is not about voluntary exchange of services or goods but a coertion by law. The definition of free market is so much broader than the peculiarities you've mentioned. Couldn't there be a free market before the fiat money existed? In any case, in my original post I was talking about forces of free market, these forces might exist in partially free market where many things are not a free choice but consequence of one or the other type of social coercion. Free market force: all it means is that the specific exchange between the parties was done voluntarily as a manifestation of the parties preferences in face of all other alternatives they have. In this sense the parties came to a conclusion that this action maximizes their utility.

I'm not arguing that free market forces are better than the alternative (you need to define what you mean by better), just saying in terms of resources allocation, free market forces maximize utility in face of other alternatives.

You can argue that this is a prisoner dilemma situation etc... but that's a fallacy as well IMO (can discuss this if more details are desired)

The question is how cheap can it get, can the energy production scale up vs cost, and how much does maintenance cost.

This is a good video about fission energy production economics https://www.youtube.com/watch?v=cbeJIwF1pVY

If one of these fusion reactor projects results in a competitively priced power plant, ok, we can reduce fossil fuel energy production towards zero in a few decades. That's pretty good for the environment but nothing really "new" is possible.

If one of these fusion reactor projects results in a 10x reduction in the cost of electricity... then we have something new. Things that people didn't imagine being possible before become possible.

Things like desalination instead of taking water from rivers or aquifers because it's cheaper. Tearing down dams because the power isn't needed. "Farms" in skyscrapers packed with artificial light where food can be produced without pesticides or herbicides because it's a controlled environment. Using landfills like mines, extracting tiny amounts of useful materials so ordinary mining becomes much less needed.

You can also think of plenty of things cheap plentiful energy could make happen that are destructive too... it is difficult to project and I assume will go in both directions.

Great work! I found the results in Fig 16 pretty interesting [0]...

From response 1, it seems that the model has very little confidence in its decision but get the correct answer while, on the contrary, in response 3, the model seems very confident in its incorrect answer. Is this usually a trend that you see with large models? How hard is it, generally, to make such models "aware" of their own shortcomings?

Twitter is covered under Section 230 as a platform and is legally immune to any content it hosts in the US. So no, it wasn't legally required to kick Trump off its platform.

So it's not following any law when it decides to host one voice and ban another. I'm sure the former Afghan government never enacted content laws that affect Twitter.

Agriculture and Industry represent 33%, more than the 29% of the total for transportation.

Even drilling down transportation, personal vehicles are a small portion (about a fifth ?) of the total compared to trucking and other business vehicles
https://depts.washington.edu/trac/bulkdisk/pdf/VVD_CLASS.pdf

And I'd expect their emissions to be way lower than trucks and heavy duty vehicles.

We could drill down the other categories (electricity, commercial and residential -- btw it's so absurd to merge these two in one block), what we individually consume/burn as private citizen is usually the tip of the iceberg.

Consuming less or different can have an impact, but only if the industries behind also follow through (image for instance you stop eating meat to reduce the agricultural impact, only for the soybean producer to go on a production rampage and destroy soils and areas in ways we wouldn't have predicted). Or from another perspective, we could have significant impact from the producers improving their practices, with little to no consumer behavior change.

Basically nothing will happen without the production side making a significant effort. If what we're looking for is "doing something", pushing harder on producers should be the way to go.
Slightly tangential - I went to install Keybase on a new Debian build last night, and discovered the installation process is broken, evidently has been for some time, and upstream (on github) seems abandoned.

Keybase, once a popular favourite on HN, lost a lot of street cred when Zoom bought them out in early 2020.

Zoom and Keybase at the time insisted this was all very good news as it showed Zoom was deeply committed to improving their security posture.

Apparently, not so much.
>Half the comments could be from Russians all we know.

If they're any good at what they do… :)

This HN thread is basically ground zero for pushing the 'Russiagate' set of arguments: namely, everything from Trump to QAnon and the antivaxxers are all totally organic and Russia didn't do any of it, in spite of their known tactics for seeding disparate opinion groups with chaos and disinformation to produce a state known as 'the Zone' where nobody knows what, if anything, is true or who is real anymore.

I've got to hand it to them, it is one hell of a tactic. It's somewhat less effective if you know it's one of their tactics. Rather than producing despair, it's downgraded to more 'fog of war' tactics. If you don't know about the tactic, despair is a more likely reaction.
If schooling were about actual education and not signaling, there would be competitive pressure to improve product quality (like any consumer good: TVs, computers, microwaves, cars…).

There is no competitive pressure to improve educational outcomes because society doesn’t really care. It’s a signaling mechanism for the top quintile and a childcare holding pen for the rest.

I ran a small consultancy for about 15 years and came away convinced that is the way to go for folks that can't get work because of a criminal record. Even though we were entrusted with some pretty serious information (we were in infosec), none of our customers except for one large bank and the federal government did any kind of independent background checks or insisted on any specific hiring practices. I think you probably need the facade of a brand instead of just Joe Blow, independent contractor, but most people just trusted it. We did have a few customers insist on E&O insurance, which may present some challenges, but most didn't care about any of that.

This might seem like a million miles away from where you are now, but if the skills you have or can develop are marketable it might be something to look into...if for no other reason than to give you some hope.
lzma is slow to decompress. Unless the bandwidth / storage costs are the primary concern, zstd has good enough compression ratio and the very fast decompression makes everything much nicer. Built-in threaded compression, long range compression, binary diff, dictionary compression, etc. are a bonus.

Many on HN seem to forget that not everyone lives near the city or works in a city, where “city” is defined by an area with enough commercial, residential, and industrial within walking distance of each other to support a car-less lifestyle.

But in fact, only a portion (of the US, at least — 31% [1]) live in urban areas that would allow them to go car-less, even if you take the housing issues out of the equation.

If the rest (69%) even lived right next to work (which many couldn’t, since in many areas, there isn’t housing close to their workplace), they’d still have to commute everywhere else.

Yes, I didn't say the energy is stored in the bonds or is released by breaking bonds. I was referring to the fact that photosynthesis (or electrolysis) is used to separate the oxygen from the carbon/hydrogen in H2O or CO2. That's where the energy is stored (in the separation of the fuel from the oxygen).
My house was built in 2018. The smoke alarms are low voltage. I remember the electrician, who installed them, told me they are DC.

Thermostats and doorbells are low-voltage AC. The transformer is standard. If you can find 24-volt AC lights, an open-minded electrician should be able to figure it out.

Related: My old house built in the 1960s had an intercom system that was ripped out by a previous owner. I found a warm transformer attached to a bare bulb light socket in the basement with nothing else running from it. I happily removed it.

An easy to read (minimal theorems) but authoritative and modern introduction to tensors can be found in the book “An Introduction to Tensors and Group Theory for Physicists” by Jevanjee (https://www.springer.com/gp/book/9783319147932).

He takes the more geometrical perspective as a tensor as a multi-linear function of vectors, from which all other statements about tensors (eg how the components transform) follows straightforwardly. Lots of other great material in this book and best of all there are loads of examples.

They are fabulously expensive for the water output you get. The San Diego one is (or was) the largest in the Western hemisphere, cost about a billion dollars to build, requires 40MW to run, and only covers about 7% of the potable water needs for the San Diego area.

Out of curiosity, are you familiar with Project Excalibur at all? I’m curious how the simultaneous-targeting of dozens of reentry vehicles from a single fission-explosion-powered sea-urchin multi-laser was supposed to work.

> On both datasets, we find that synthesis performance scales log-linearly with model size

This "scaling law" observation is starting to become a major trend in NLP [1] and other other modalities such as speech recognition [2] and protein structure/function prediction [3]. Do you have any insight or commentary to offer regarding the next step in improving program synthesis? For example, will techniques to scale up model size continue to be a primary focus (eg as in [4]), or do you see improvements in Transformer and attention based architectures as essential for pushing the limits of what has been achieved by you and your colleagues?

> We find that even our best models are generally unable to predict the output of a program given a specific input.

What do you think about leveraging unsupervised training to improve program synthesis? Could synthesized programs be executed on generated input in a way that supports contrastive learning [5]?

Interesting, that makes sense. I'm thinking about a CLI analogy: you could write a program in C for the logic, some table specification markup language for the terminal layout, and a stylesheet for the colors and text styles. It would feel so cumbersome. The distinction between creating a document and a program is critical.
Of course not. Reducing carbon emissions and avoiding climate change has never been viable, because it lowers people’s quality of life now for the benefit of people not alive now (or in decades past).

The only viable solution within the timeframe humans had was to reduce fossil fuel consumption in total, from some combination of reducing per capita consumption and reducing population itself.

However, it is a prisoner’s dilemma, and there was never going to be unity in reducing everyone’s consumption and hence quality of life, especially not from the 80% of up and coming people around the world who are looking forward to enjoying life like the upper 20% have been.

The pull seems to have been to get Canada to either sell their own water or even bring down water all the way from Alaska.

I tried to find it quickly but can't. I seem to remember hearing on the radio about some 100 year contract to sell water cheaply from BC or Alberta to CA. So potentially it's one of those scrapped plans or maybe they figured how bad the plan was just buried it. I can easily find propaganda trying to co Vince us that Canada has so much water and that it magically renews itself that it would be stupid not to sell it. Over and over.

Which is in stark contrast to my experience here. We have had less and less snow in recent years. We've had rivers running lower. We've had watering bans and lawns looking like we are in Arizona (yes, an exeggeration to make a point) more often in recent years. This year is an exception with more normal sun/rain cycles returning after a really dry spring (lawns recovered - who cares - some crops not so much, other are doing much better than in recent years)

LZ is popular because it's computationally efficient. When random memory access is slow but sequential access is fast, you want to encode substrings instead of individual symbols. Explicit higher-order probabilistic models require a lot of memory and generate too many cache misses. Implicit models based on the Burrows-Wheeler transform also have poor memory access patterns.
