I concede the 70%. I agree with your calculations too.

But you also concede that you can use LNG from time to time. Which we can later switch to H2 or NH3.

Right now, all the natural gas power plants in the US produce about 12% of the total (gross) emissions. If we use these plants only when there's not enough electricity from solar, wind, hydro and nuclear, we'll reduce their emissions by a factor of 10.

What is the point in building thousands of reservoirs then? To reduce that 1% to 0%. Which we'd reduce anyway once H2 or NH3 become cheap and abundant enough?

By the way, the EIA made a handy comparison table for various power plants [1].

A "combustion turbine - industrial frame" is by far the plant with the cheapest capital cost, only $785/kW. Conventional hydro is listed at $3083/kw, with a fine print footnote that this cost is the least expensive plant that could be built in the Northeast (where the geography permits).

So, the cheapest possible conventional hydro is 4 times more expensive than an brand new natural gas power plant. My point is, we don't need a brand new one. We can just keep existing ones (and we don't even need to keep them all).

I'm not sure why you're so hostile toward this idea...

I know basically nothing about ecology, but it seems relatively straightforward to think of reasons to study biomass. Think about food chains. Food is energy is biomass (as you mention). At a basic level: if you know that a certain ratio of biomass is needed (or expected) between two stages in a chain, then you can keep tabs on one of those stages, and when you see biomass decreasing, it's a signal that the food chain might be soon disrupted. In a food chain, the number of animals seems mostly irrelevant (except in cases of near-extinction), but the total energy is highly relevant.
Sounds like Vroomfondel and Majikthise demanding rigidly defined areas of doubt and uncertainty.

The hysteria around Meta earnings report has been really fascinating to watch. Starting most recently with the activist letter telling Meta to give up on the Metaverse.

The market hates innovation - until its successful, then loves it. Meta making such a big bet on the future, win or lose, is inspiring.
I'd still rather have basic SQL (that is enough for most) to just be there, for the apps where including SQL engine would be vastly more code than app itself.

If we had block API and SQL (it could be just a concrete version running from WASM itself, to not bloat browser itself) it could save a lot on app size. App then could look at browser version and decide to use that or to download newest one to run.
Totally. Guesstimating interest rates for various types of tech debt is a fun exercise:

- Using a single-letter variable: 10% interest on any code which uses that variable. That is, any work involving that variable takes 10% longer than it otherwise would.

- Tests run for long enough to get distracted: 1% interest rate on the production code per second of test runtime. If this calculation could be worked out to anywhere near ballpark accuracy it would be a huge benefit to knowing which language/framework to choose for production/test code.

- Flaky tests: 100% interest on the test code + 10% interest on the code under test, mostly due to having to re-run the entire test suite in CI on an irregular basis.

- Not having tests for a piece of code: 1,000% interest on that code and anything that depends on it. Basically, overall and in the long run I'd expect any work involving untested code to take ~10x the time it would take for well-tested code, due to having to figure out what it's meant to do (explained and proven by good tests), how it does it (generally pulled apart into easily understood parts if it's got a good test suite), and why the changed code doesn't work.

This is obviously not scientific, but it would be cool to have the time to work out what a framework for such calculations would look like, and applying it based on experienced people's estimates.
This is somewhat more complex for the developers of websites but dramatically less complex for the developers of web browsers, and that is where we really should be caring: the complexity in the browser leads to both increased attack surface and nigh unto
guarantees there will only ever be a single good implementation of the browser. Both standards and security critical systems should be easy to build and easy to reason about.
Yea, sounds like BS to me. Imagine Elon reading code printed on hundreds of thousands of real paper from thousands of developers.

Makes no sense.
I don't disagree, but the people most angry about being kicked off Twitter are also the people who insisted that net neutrality was "Obamacare for the Internet".
You can be negative or enthusiastic about this. Either way the trend indicates the impending death of an entire occupation of creativity. I envision an AI that can replicate Kims art and replicate it better and faster.

Now for the first time in my life I can see the future beyond science fiction. Where machines are capable of doing everything humans do, and do it better.

The outrage is a violent attempt to stop the inevitable. I sympathize. Because artists won't be the only victims of this change when it's all over.
It is intuitive but there are so many ways to do it wrong, and the ways to do it wrong are often promoted as the best way to do it.

In fact, I don’t know if physical exercise is actually taught correctly by any single person. Each teacher may help you in one way and (sometimes physically) hurt you in another. The only way to prevent that is to become an expert yourself.

I’ve read about three books worth of information about weight lifting, stretching, massage. I’ve been to several massage therapists and physical therapists. I’ve had a personal trainer. I’ve consistently practiced being active, and even did sports when I was growing up. Despite all that, I still haven’t reached my simple fitness goal of not having muscular pain.

Physical inactivity can be caused by injury. In that situation, both activity and inactivity can have serious negative consequences. Navigating someone of a situation like that isn’t something many health professionals are capable of doing, let alone random people.

I’m 28, maybe you are still 22 and don’t know what the consequences of your training on an aging body are yet. Or maybe your legs aren’t uneven sized (as many peoples are) and you don’t have to deal with the consequences of that.
> It's largely forgotten now, but the first President Bush had gotten the U.S. into a war in Somalia, but the incoming President Clinton knew a quagmire when he saw one, and was able to cut and run quickly, because he was not (as Putin is now) forced to pretend that it had been a good idea in the first place.

This is an extremely extremely extremely misleading characterization of a United Nations humanitarian action that started after Clinton was elected. https://en.wikipedia.org/wiki/Unified_Task_Force

"American troops had first entered Somalia during the Bush administration in response to a humanitarian crisis and civil war. Though initially involved to assist humanitarian efforts, the Clinton administration shifted the objectives set out in the mission and began pursuing a policy of attempting to neutralize Somali warlords." https://en.wikipedia.org/wiki/Bill_Clinton#Somalia

It's essentially the complete opposite of what you said.
Agree. Although checksums are smaller and easier to copy/paste. Same with a url.

I download the script from A, and the checksum from B. And then I verify them locally. So A and B both need to be compromised. It all assumes the script was safe to begin with, and this just verifies that nothing has changed

Are people paying for credibility? Hate to break the news to you (ha!) but the news you’re going to see the most is the news that sells the best. It’s all about those Benjamins. You can’t expect good things from a society that has compromised all its ideals and prostrates itself for money. Certainly not journalistic integrity - unless it sells. Which it doesn’t.
Don’t quote me on this but the last time I checked it was roughly…

~600 deaths 35,000 hospitalisation due to car accidents.

~85 deaths 13,000 hospitalisation due to cycling accidents.

But in any case when walking in the city I feel safe walking with cars. But I don’t feel safe with cyclists. They rush through red lights. Rush through intersections while people are crossing. I’ve witnessed accidents occur due to cyclists not following the laws. If they followed the laws and slowed down. Stopped and gave way like they are meant to. I wouldn’t have an issue.

> What makes lidar a better choice for many applications, including archaeology, is that the wavelength is about half a micron – tiny relative to radar wavelengths, which are measured in centimetres or decimetres. For details of a relatively small spot on the ground, lidar provides a precision that radar cannot match.

That's still not a great deal for people looking to preserve capital and invest after a crash. It's very likely that the worst of the market declines will be within the next year. Markets are forward-looking, so once they realize that there will be long-term economic pain, they correct quickly. Oftentimes the steepest stock recovery is during the worst of the unemployment pain.
To a lesser extent, same thing with ISIS. When LiveLeak was gone, and their propaganda videos were pretty much scrubbed from the web, we lost a lot of actual history, as abhorrent as it all was. It's going to be easy for people to forget how bad all of that was, and more importantly for me- most of the countless videos of them using American supplied TOWS against Assad while also filming the mass genocide...all that is gone, and it's much harder to prove the connection was ever there.

Same thing with Libya and Gaddafi, gruesome stuff was done by western backed rebels, including a revival of the black African slave trade and just killing black immigrants in Libya, and all of that is nigh impossible to prove now.

Ya, for sure. We've got a very similar device lineup to yours. Apple got a lot of backlash last time and I'm sure there will be a lot of upset people this time too. But, there's also a group of people looking forward to the change.
Actually, I thought the issue with automotive is that 48V really isn't enough.

My understanding is that actuators want to be operating at much higher voltages and that 100V-ish is the lowest they really want and that modern actuators would much prefer to be up at 200-400V.
Inefficiency doesn't matter if you are storing curtailed energy.

If it makes more financial sense and uses less resources to overbuild solar 3x and curtail 60% of the energy than paying for fuel, then you have 2 units of energy you have already paid for spread out over 6-8hrs/day.

As long as using your $300/kw electrolyser at reduced duty cycle is cheaper and less resource intensive than mining and shipping gas, you do it.

tangential to your question, i think it’s worth pondering what makes (or would make) a per-page moderated/curated search engine like Wiby valuable, though.

Wikipedia articles are easy to find. they’re all generally good quality. you don’t really need a new search engine to make Wikipedia more accessible.

Personal websites, on the other hand, are a mixed bag. there’s a tremendous amount of worthwhile stuff out there, where one page might explain how to solve a niche technical issue and the adjacent page might just be the author sharing photographs of a recent hike, or their wedding, etc. currently, both of these pages tend to be low-ranked on most search engines. i believe one prospect for Wiby is to bring the former to prominence.

it’s definitely not a general-purpose search engine like Google. but try searching “raspberry pi” or “home automation”. on Google you will get pages focused narrowly on products: where to buy rpi’s, a dozen different home automation brand webpages, etc. on Wiby you get blogs documenting things people built related to rpi or home automation.

it could be something like a search-based, topic-agnostic Hackaday.

it’s not perfect. it only has a few relevant results for each topic. but there are certain specific types of results which are near impossible to find on Google but can be found on Wiby. maybe that can be valuable. maybe it will fade way. i won’t forecast the future, but i am intrigued.
The "he had very rich parents" is often used to reduce one's achievements. A quick google search shows there are over 60 million "millionaires" in the world, yet less than 1% know how to turn it into a billion.

Why go for LTE when Wi-Fi is so much more feasible?

I mean, 10 bucks for an AP isn't far fetched whereas LTE antennas alone would explode in budget, even when considering to use OsmocomBB with super old hardware/phones.

And every phone these days got Wi-Fi anyways. Most meshnet solutions rely on Wi-Fi so you wouldn't even need to implement much software for peering.

Musk has media attention, but I'm not sure it's much of an advantage at this point.

I tried getting a solar system from Tesla, and it convinced me not to consider their cars. I know it is a different side of the company, but I ended up with a used electric BMW. I was resigned to dealing with the B-hole stigma around having a beamer, but whatever. It's a nice car, environmentally friendly, and was inexpensive.

That's not what happened. Instead, Tesla owners say things like "I got the Tesla before Musk went nutso roll eyes, and it's actually pretty good, but I'm not sure I'd buy another one..."

I'm surprised how quickly the Teslas went from being a status symbol to a faux pas around here. Maybe it's a different story in less liberal areas.

However, unless I'm missing something, social signaling / image management is way more important to the Twitteratti than people buying commuter cars / kid taxis.

(Again, whatever. It's a car, not a political statement, but I've seen more than one Tesla owner apologize for owning one.)
Traing models to remove water marks first.

If artists cared enough, they need to make an union of some sort and lobby for non synthetic art labelling for protection like big Diary and get AI generated art to be branded like GMO foods.

Radar does work, there's just a trade-off between frequency and resolution. LIDAR is way up in the near-optical regime, so it has very poor penetration but the resolution is so high that you can see the small gaps in the canopy. Importantly, you can also do fancy signal processing with the reflectance and multiband stuff to distinguish man-made objects from foilage. That's uncommon in the archaeology world (unless using data where that's already been done), but the military and commercial people take full advantage.
Creating a specific model from one artist shortly after their death is just plain gross and deserves backlash. It's not a good proxy to talking or thinking about these issues more carefully.

I think there is a big difference between feeding an AI model a wide swath of an art style like anime and creating and using a model.

Taking one persons particular work and style and copying in competition or near competition with that person is something that I don't think is inevitable and something I would be happy to see the expansion of legal protection for.

I know I will get downvoted since HN hates legal protection for artists, but I just don't see the societal benefit from allowing an individual human to be replicated by AI without their consent.
No. But there are people with ambitions to create robots that will take over my job and yours and everyone's. It's looking more and more like the inevitable future and all people talk about in the comments are trivial things like "intellectual property"
