If you look more into it, it's not clear at all that fusion is actually a promising source of power. None of the currently contemplated technologies have any realistic chance of producing power anywhere near competitively in cost, even ignoring the huge research costs left to get there (no currently planned fusion experiment has any hope of producing more power than it consumes).

This article (and site) are pretty great, and helped shape a lot of my worldview. It tends to throw a bucket of cold water on a lot of the arguments regularly made on this website, though, so I'm surprised to see it here.
I didn't post it.
The West's efforts have been to continue the war, not to stop it. When you're supplying arms, you're not acting to stop a war.

Not saying that Ukraine didn't have a right to be defended, but it should be pretty objectively obvious that the war would have stopped long ago had the West not intervened. This would have been unjust and a massive slap to the people of Ukraine, and arguably worse for the world in other ways - so I'm not saying that we shouldn't have supplied them.

But we also can't claim we are doing what we can to stop the war: we're (at best) doing what we can to help the right side to win, while prolonging the war.
And even that, the heavy elements of the earth (basically anything heavier than Helium) only exist because of the sun's predecessor, making the heat from the core also just recycling from fusion.
Unecessary expense. These are 1099 contractors who are responsible for their own taxes. I just need an inexpensive way to transfer funds to them.

> I'm just giving general advice about how it's good to keep things business and personal things separate in a public forum where others reading can also learn from the advice.

Literally nobody on Hacker News needs this advice, and in general, unsolicited advice, especially from strangers, is unwelcome.

If you have something like "here's a hidden Terminal defaults write command I discovered that is largely unknown and will solve your problem", that might be a different matter. But your advice is so obvious that it doesn't need to be said at all. In an ideal world where everyone had unlimited time, unlimited money, and no other constraints, everyone would always follow the "good advice", but in a non-ideal world there are many tradeoffs to consider, and if you're talking to a stranger, you don't know their personal tradeoffs. Of course I've thought about these things, as any intelligent person has, and made my choices based on my circumstances.

There's a level of conceit in thinking that other intelligent adults need advice like this. You seem to believe you're being helpful, but effectively it's insulting the intelligence of others.
What if I told you commercially viable fusion power has been 10 years away for the last 40 years? What if I told you it always will be?

Investment in something that might not pay off is wise if it does, and foolish if it doesn’t.
If you plug your solar panel into some water when you have surplus sun you get hydrogen which burns fine in a combined cycle plant.

If that's too annoying to store you can get it hot and squeeze it over some nickel to get methane.

Electrolyzation becomes cheaper than mining methane for hydrogen (and thus ammonia) production if solar hits the $0.2-0.3/Watt threshold somewhere (which is predicted to happen in 3-7 years).

It's complicated and expensive, but I'm not sure I'd bet on a sabatier reactor (or hydrogen storage if it gets cheap), an electrolyzer and 4x the solar panels being more expensive than a fusion reactor with the average output of 1 unit of solar.

Plus the sabatier thing means we don't have to upgrade all the heating furnaces and expand the grid to have 8x the capacity.

Fusion will be real handy where power density is king though. And if there's some non thermal way of getting work out of it, I can see it being cheaper.
I have a small 5kWp PV at home, with a small lithium storage (8kWh) just to cover my arse in case of outage, since here (French Alps) there is a very big day-night thermal delta it's very good in summer, where at night I just need the VMC in passive mode and A/C only during the day, for the rest it's enough for heating sanitary water almost ONLY from the Sun, winter included, and to run some appliances (dishwasher, washing machine etc) in self-consumption. Doing more is needed for trying to charge an EV from PV during the day, likely the double at minimum, but to heat the house in winter OR:

- I need a very expensive battery (60kWh/~30k€ at least just to avoid big daily deep discharge cycles) who might or might not last 10 years with an expensive geothermal heat-pump 15k€ at least;

- I need a giant insulated, probably underground for mere easiness of design, pool and PV plant (I do not know how to estimate but surely few swimming pools of water and enough PV to heat it) to store enough heat for the night.

Both options are ridiculously expensive especially since they still NOT give autonomy since they can support day-to-day winter IF the Sun shine enough, witch might but also might not happen. Perhaps in a future H₂ from hydrolysis will be on sale to offer a fuel-cell third option, but I imagine it will be even more expensive.

So far it's still FAR, FAR, FAR, cheaper using the grid + an emergency wood based heating. Long story short I might accept investing (I'm actually in the planning stage) a 15kWp or so PV for an EV charging (WFH so without daily car usage) but trying more is just money gifted to some company pocket. Oh BTW that's JUST for private homes. We also have public buildings AND industry...
Sounds like an idea for a SaaS business.
If you get a kick out of neat technology then you should be able to build your own cool stuff — libraries, tools, and the like — without needing to reach for a particular language.

I work on a large and boring Python codebase and I don’t need niche technologies to scratch my CS / hacker itches — healing technical debt with carefully considered redesigns that delete thousands of lines of code and produce v2 of something with 10x the usefulness is what gets me excited about work.

Do you like cooking, and have you heard of Keith Floyd? He was famous in the 1980s for pioneering the travel cooking TV show, getting out of the studio and cooking on location in borrowed kitchens of French farmers, fisherman’s galleys,
firesides in the outdoors as well as whichever corner of a professional kitchen he could
beg or borrow. He brought French cuisine to life, on screen in situ, by working with what he had available to him and making of it what he could, all with good humour and excellent results.

It’s a nice metaphor for producing business results no matter what kind of facilities you have available:

> So the only thing it offers is being cheaper than renting a car for one extra day for long journeys

Nope. It also offers not having to drive. I can read a book on a train, which I can't do in a small car even if I don't drive because I'll get car sick. I can even walk around and have luch in the train restaurant, go to the bathroom without having to stop.
This was an awesome overview of current state of fusion attempts!

Trains are ideal for middle distances. About 1 or 2 hour flight equivalencies. DC to NYC, Tokyo to Osaka, SF to LA or Seattle, The Houston, San Antionio/Austin, Dallas triangle, etc. NYC to SF is not ideal for a high speed train, take an airplane then.

With a high speed train you can have downtown to downtown service, not need any security checks or slow onboarding / off-boarding processes and more, which eats about 1.5 hours minimum on each side.

I think you're being overly generous here.

He doesn't offer examples of the harassment he reported. Even if he had, he's comparing Twitter AI-flagged revenge porn posts against user-reported harassment posts. The former is pretty clear cut and Twitter flagged it themselves. The latter may be a judgment call and was probably reported by the alleged target. His rudeness undercuts any such argument anyway, since we can't be sure the rep who reviewed his case didn't just see this and not waste his time on it.

His main point seems to be "Twitter sucks." I agree. It sucks. So I don't use it.
battery for solar installation is at the point where between 2-6hrs of capacity can be economical viable.

Maybe in a few more years/decade/s we will reach a point where in some places in the world it will be economical viable to have exclusive solar and battery, and that assuming prices will continue to drop and that there won't be any resource or physical limitations. Then we got colder climates where solar + battery is unlikely to ever become viable. Exports of solar generated green hydrogen could solve that assuming that the technology for that becomes cheap enough.

Multiple different directions where specific technologies could be economical dominant in the future.

It's an equal level of insanity that technologies like thorium breeder reactors haven't been getting whole number percentages of first world budgets, especially considering how extremely high of a priority climate change has become and how costly the alternatives (e.g., disaster mitigation) are getting.
You appear to think that "conservationist", "endangered species advocate" and "environmentalist" are all synonyms for "climate activist"? Your previous comment claimed there was opposition from "climate activists", and these are not examples of that. The BattleBorn situation seems to be about about tourism and similar values (not climate activism), the Ivanpah situation looks like it's about species conservation (not climate activism).

Don't get me wrong, I am very frustrated by people who see themselves as environmentalists, for whom climate change (and thus non-carbon energy sources) is not the top priority. I think they have wrong priorities. But that doesn't mean they're hypocrites, they're just (IMO) wrong.

All that said, I agree with your topline observation that we need all the help we can get.

Often what is considered success at L6 is different than at L4 so this should be done very carefully. Generally at lower levels writing good code is much more important.

I’ve seen new engineers that tried to rush senior eng behaviours and they didn’t do well in performance reviews until they corrected their behavior. You need to prove you can be a baseline contributor before you start dreaming big.
Well, the streets aren't free, because you need to buy a car to use them. That's a little pedantic, but I think it's super relevant.

The problem is that as a passenger/consumer, with a car, it's very easy to decide how much to pay for my own personal level of ride quality.

I can spend $2k on an old Camry, or I can spend $200k on a Bentley, but either way, I have almost total control (potholes notwithstanding).

It's really not possible to have that kind of personal control when you're looking at public transit.

The most effective producers because of non-economic reasons (i.e. geological properties). So they end up being one of the largest investors in the world because of geology.

The market does often not do pointless or dysfunctional things because markets tend to give most capital to the most efficient users of that capital. But those rules do not apply to things like oil where there are significant non-economic returns (to an extent, the Saudis will always lose all their money, I have named other reasons who repeatedly do the same thing...but it is not terribly efficient spending resources to prise capital from them).
If they were the same cost I'd pick the train every time. I can relax, sleep, read a book or get some work done.

I don't think we disagree here. He's right about the ban, but he's made the situation more complex and he's not right about the whole situation.
Yeah, this reads like a standard dessicant dryer applied to HVAC. I can believe that it costs less to run the dessicant dryer and then cool the air than a standard AC. This is often very true in compressed air, because you are trying to compress air, and if your air is saturated with water, you are producing a much smaller volume of compressed air vs using dry incoming air. Water is relatively incompressible, so it's actually somewhat remarkable how true this is (IE what volume of air you get out of 80% humidity intake air vs 30% humidity intake air)

The main issue they are likely (IMHO) to hit is contamination. Compressed air is filtered before being dessicant dried to avoid getting oil/dust/etc on the dessicant, because it will reduce efficiency and destroy adsorption capability over time.

Compared to compressed air, residential HVAC systems are not that well filtered (commercial can be). There are lots of people using nothing or random low-MERV fiberglass filters. That will destroy dessicant capability very quickly.

So i have to imagine they are starting commercial first.

I would strongly disagree that we're losing players to rugby. While rugby is (IMO[0]) the second sport in Scotland far more youngsters play football than rugby, and in practical terms the potential for making a career out of rugby is more unlikely than football. So I don't think that we're spreading ourselves more thinly than Croatia are, I think there's something more to it than that.

[0] - I actually read a while back that Cricket had more registered players than Rugby in Scotland, but I take this with a pinch of salt. But make no doubt about it, our sporting focus is roughly similarly focussed on Football to Croatia's.

i don't know the specifics of this particular person but not all people in the panama papers are "evil" or dodging taxes but just people that are high profile but need anonymity for one reason or another. film crews use shell corps for legitimate reasons because if the people they were coming to to rent a venue or rent some stuff for a shoot were to know the reason for the rental they would jack up the price to AAA blockbuster movie prices instead of the normal rate. they probably should be paying those blockbuster rates but it is not illegal per se.
That's not the novel part, the novel part is thermally connecting the regenerating and saturating sides. I think the tldr is that the regenerating side is evaporating and thus cooling? The work input into the system (aside from fans) is the vacuum pump.

They're using vacuum to dry the desiccant; the mechanism to seal the two chambers well enough to pull a vacuum seems like a high failure point.
Along with small and or very high population density nations.

India is going to end up with perhaps two billion people and will have extraordinary population density/spacing problems. They're going to desperately need huge numbers of nuclear fission power plants or fusion plants to provide for that. They will not have the space for epic scale solar farms. Singapore, South Korea, Taiwan, Bangladesh, Pakistan, Philippines, Vietnam, Israel, Belgium, Netherlands (among others) are in the same space vs population situation. And given the population explosion across parts of the Middle East and Africa, it's a certainty nations in those regions will have the same problem as well.
I'll admit that my initial comment was somewhat biased coming from another thread in this discussion discussing verbal abuse of the moderation team. In that context, my assumption was that they were human, naturally. Your point is fair, though, especially considering Twitter's scale.

What are you talking about? China's economy is absolutely capitalist, even modeled in the same way (Shenzhen economic zone akin to Ireland's) with some state intervention as of late. China's adoption of capitalism, as well as post-1991 India, is the precise reason for flourishment and lifting millions of people out of poverty.

You missed the distinction between counting passengers on a platform or in a bus, and figuring out what people are using public transport for. “When people get on at this stop, how far do they travel? Are they having to sit on trains for 2 hours or do they only go a few stops? Should we draw a new line here or there?” That’s a different question from “how many trains do we need to dedicate to this line between 8 and 9am on a Thursday?” which can be answered by counting. You can kinda guess with the numbers only, but many paid transport systems have had near perfect info on this their entire service lives. It would be weird to lose it.
Again, it caused two decades of political upheaval in South America, multiple military dictatorships, hyper-inflation, economic chaos, etc. (this was all mediated by US banks btw, who were the ones doing the lending...but the reason they were in that position is because ME countries insisted on depositing all their money with US banks).

Right, but the reason the "free market" gave that money was because of the geological properties of KSA, not their ability to invest capital wisely. The failure to realise that this is a path to nowhere is the fault of our politicians however.

For comparison, if I am raising capital for a hedge fund and I start talking about the geological properties of the earth under my house then I will carted out. But that logic is how KSA are one of the largest investors in the world...it is going about as well as you might imagine (the same is true for Taiwan, Japan, Germany in more subtle ways...they have created systems that expropriate wealth from consumers for investors, and those investors essentially spend a huge amount of time setting that money on fire...the only country that has got out of this is Sweden, which decided to give substantially all their material wealth to one family, the Wallenbergs, who turned out to be the some of the best investors globally...but that is a rare example of arbitrary wealth allocation ending well).
Ah, you are right. I can't believe my eyes skipped over that.
