The idea of harvesting energy from graphene is controversial because it refutes physicist Richard Feynman’s well-known assertion that the thermal motion of atoms, known as Brownian motion, cannot do work. Thibado’s team found that at room temperature the thermal motion of graphene does in fact induce an alternating current (AC) in a circuit, an achievement thought to be impossible.

Even more, the result is essentially claiming to violate the Second Law Of Thermodynamics. HN should be flagging this sort of crank claim.
CME forex futures has circuit breakers.

There is no such thing as a “forex market”. You are trading directly with a counterparty in forex. Those contracts do sometimes stipulate circuit breakers.
A blitz for Kyev and surrounding and killing the government didn't seem so unlikely given how close it is to russian territory and given how small the Ukrainian army is.
This way of thinking is a great way to ruin a company. After that every employee will think about whether Apple will give them just the minimum so that they don't leave for another company.

It's a great way to destroy morale.
Yeah - as a user, I specifically _don't_ like Apple's approach of breaking things all the time.
No, it's not. Currency futures have proven time after time to be nearly perfect reflections of actual forex movement.
I remember as I was beginning to have my doubts about Facebook (cerca 2006) I realized that I didn't really want all the random thoughts of this extended group of people I barely knew started trimming down my friends list to just my actual friends. In the process, I removed a friend of a friend whom I had barely spoken to, and... they noticed.

What resulted was a heartfelt apology to me from him, for anything he might have done to offend me. I responded explaining the situation, but the entire interaction was extremely awkward.

The win is for the end users. If you're relying on a service from a company, and they decide to stop hosting it, or make a change that it is incompatible with your workflow. It is nice to be able to host your own version of it. I can't even fathom being against it.
Charging by the hour is a great way of making users minimize use of your software. This is exactly not what you want your users to do. Some idiot will try this, but will quickly learn and revert or go under. Especially dumb with something like MS Office where the whole system is designed to keep users in the system 24x7 and reliant, rather than encourage alternate solutions for bits and pieces. Slash your software licensing costs by pasting text from notepad rather than typing it in MS Office, survive this months budget cuts, eventually realize you can do without the software entirely.
> Putin has a doomsday device that he doesn't actually want to use.

I'm not so sure about that. I feel it depends on whether Putin still has at least some marbles left. If he does? Yes, he realises that leaving a legacy of "war criminal who nuked Ukraine" isn't actually what he wants so the threat of nukes is making a point to NATO to stay out of it. If he's lost all his marbles, though, or if he's so far out of touch with reality as makes no difference? I could see him nuking Ukraine out of spite if it's clear he won't get what he wants, in a sort of "If I can't have you, no one can!" move. Assuming that there isn't a coup before that, or that him giving that order doesn't trigger a coup, etc, etc.

I think [0] Putin vastly miscalculated public sentiment in Ukraine. His attack was based on the premise that Ukraine's government is essentially a puppet state of the west with little popular support in the country. This is been how the Russain state has been telling the story since 2014. He probably expected this to go like the Taliban's expulsion of the US from Afghanistan in 2021. Most of the people would support, or at least not be too bothered by it, the government would flee, and the few government supporters would have no will to fight. Then he could install a sympathetic government as there is in Belarus. But obviously, popular support for the Ukrainian state turned out to be much, much higher than Putin thought.

As they say, don't get high on your own (propaganda) supply.

Nah, liquidity is too low. Spreads will kill almost all arbitrage opportunities.
To continue with what your saying.

Yeah I am already wearing a sweater, warm pants, wool slippers with socks and a beanie / hat. The hands are unexposed and I'm thinking at this point I need a different slippers that are bit more breathable. Also staying warm with breathable fabrics can be somewhat deceptive, because your dehydrating yourself faster via sweat your not perceiving.

Wool doesn't work well for me due to skin issues unless I cover it with a layer of nylon / cotton. Yes I've tried good merino wool, and it's still minorly irritating. I've given up on most wool that touches my skin.

Also my apartment is in a fairly temperate place, and what is hot / cold is a bit weird. The floor is a fairly cold hardwood floor, and I think it sucks a lot of heat out somehow. I'm not in a place that is consistently cold, it's only cold for like 4 months, so places here are not very well designed for it. It's also not carpet which probably solves a lot of the cold floor problems via it's built in insulation.

Also I'm more perceptive about my body state than probably most people and try to avoid wearing antiperspirant when I know I'm not going out that day with WFH. Your are probably blocking a lot of the sweating your armpits would do in this modern age as a result, and I believe we should making clothing that keeps that area a little bit more cool.

My internal body temperature can run hotter if I start eating a lot of carbs and more calories, but then I start consistently gaining weight so I don't do that.

I'm also more doing this as a challenge, I can definitely afford to just heat my room to t-shirt levels and put rugs everywhere, but I'm trying to figure out clothing that would work well without it while using a computer for hours. I'm not raynauds level of issues, but it makes sense this is mostly an computer worker issue too.
> This is objectively false.

Nonsense. We live in a society which is maintained with public money, and very few businesses would be profitable without that. Heck, money itself is a public institution.

> Zoning is a can of worms that is outside the scope of this discussion, but I would have plenty to say about how this exactly is abused, in another thread actually on the topic.

It's absolutely on topic when you're suggesting that we should apply much stricter rules to employment relations than we apply to every other interaction between citizens and government.

> Needless to say, being the market-based beneficiary of poor laws is everyone’s right as a citizen in our Republic today, in a way I find disagreeable, and if they can manage it. This is also why you shouldn’t also get to be both a voter, and on the government’s payroll, and have a union.

> it is a moral hazard to have a class of citizens who are able to vote for both sides at the negotiating table when what’s at stake is somebody else’s money.

Banning unions does nothing to address that - people are still "on both sides of the table" when negotiating as individuals, they're just a lot more reliant on their individual capabilities. Requiring everyone to do their own legal research and individual negotiations is both grossly inequitable and also could never be a full solution to that kind of issue - if there's some principled problem with citizens negotiating with their governments, that needs to apply to powerful individuals (including but not limited to higher-class government employees) too.

(And again, what's so special about the employment relationship? Surely the same logic applies to residents' associations, or advocacy groups, or professional associations - there are all kinds of groups of citizens that regularly find themselves on the other side of negotiations with those same citizens' elected governments)
I saw a comment on Twitter from a Russian expat saying something like “if the EU offered NATO citizenship to every Russian soldier, this war would be over tomorrow morning.”

China doesn't also really seem to want any part of this drama. They're being dragged in because historically they're an ally of Russia but really at this point China has to view Russia as a liability to its own long term ambitions.
Regardless, using human emotions in geopolitical discussions is weird. I don't think China is afraid of the US, I think China is doing what China thinks is best for them, which may include going along with the US, or not, or doing something inbetween (most likely).
This is very good idea. Not sure about Paraguay as it will just guarantee nothing but miserable life but if offered resettlement into West I think they would leave in droves. Putin might wake up without the soldiers.

Not necessarily. Just use the secondary sanctions mechanism, same ones that make selling Russian gold problematic. Crypto, unlike gold, also permits one to publicly flag tainted wallets.
> There is no such thing as a “forex market”. You are trading directly with a counterparty in forex.

That’s called a market. You probably mean a market maker, who may buy or sell a security at a market price without an available counter party. Any market can have a circuit breaker. But usually forex doesn’t because the whole point of the market is to provide a way to convert currencies when needed, compared to stock markets where the main goal is to efficiently allocate capital.
Not necessarily a strong Ruble - but a steady Ruble . A rapidly decreasing exchange rate in this case has a similar effect to a high inflation rate. The buying power of savings (especially imports) is rapidly dwindling which makes people feel poorer and worried their live savings from hard work will be worth less.

"I am pretty sure Putin and his team already have thought about the different scenarios". After Kudrin left, there is little evidence of a coherent economic policy from Russia. There is little evidence that Putin even remotely considered the economic impact of this ill advised adventure.
And of course in that case the information is of immediate importance to you, however if I'm 16000 km away, I'm not sure that I need blow by blow reporting on events that may only impact me through increased costs of goods.

I have absolutely no way of impacting events in the Ukraine, even if I decide to contribute to a charity or try to influence my local member of parliament there is still absolutely no benefit to be gained by anybody (except perhaps the media) of me consuming this coverage.

I can however benefit significantly by avoiding news reporting that is going to continually trigger primitive fight or flight instincts and leave me in a high state of stress.
It's unlikely that we'll break any of them, but it's possible. One can hope, I suppose, but I wouldn't put money on it.
While certainly there are some institutions where an error allowed to persist for a specified duration becomes irreversible, I see no argument that there is such a rule applicable to the UN issue at hand.
Some time ago there was a tweet making the rounds with a joke along the lines of:

I started to wonder if there is a market for a startup that simply takes all of the best-in-class open source alternatives and hosts the whole package that is commonly needed by companies. Would anyone here use something like that, and why don't smaller hosting providers invest in something like this? You see a lot of them offering basic Webmail/Calendar, but couldn't they go beyond that and use that as a possible revenue stream to compete with the big cloud providers?
Sure, but it's like the boy who cried wolf. If the tool keeps saying things are a bigger issue than they are, then people will stop believing the tool.

Either I completely misunderstand you, or you don't understand thermodynamics at all.

Do you know how the Carnot cycle works, and more importantly, why no process to generate electricity from heat can be more efficient?

> If you’re generating energy at a rate greater than you have a use for,

Huh? Why would anyone do this? Just turn off the excess capacity.

(Do keep in mind that when we produce electricity, we necessarily have waste heat. That waste heat has energy, but it's not energy we can use.)

Any kind of heat engine essentially works like a water wheel: you take heat from a high temperature source (water from a source at big height), you send it through your apparatus, and out comes heat at a lower temperature (water at a lower height) on one side, and some electricity on the other.

> ... then you want to radiate it back into space, yes. Neutron beams would be a cool, perhaps fanciful yet potentially practical way of doing that in a concentrated manner.

Huh? If you can concentrate the waste energy, it's not waste heat. You'd want to use it instead of just bleeding it into space. Do you understand that?

You'd use that concentrated form to run another engine.

> In five years, it will be metered by the nanosecond to end users. This is not only predictable, but inevitable.

The only people working at nanosecond precision are likely to want a long-term project budget to allow for budget planning.

> [..] specifically MS Office for business and Avid Pro Tools for film, will be metered in seconds, rather than distributed in a sales or monthly subscription model.

Businesses have budgets to manage, and those are typically allocated on the order of months or years. Not only this, but the seconds interacted with these pieces of software would incentivize users to keep closing them, breaking workflow.

I suspect we will see more license pools shared at companies for expensive software, with the possibility of pulling out additional licenses on-the-fly at an additional cost.

On the other hand, an industry that may want per-minute billing is lawyers, who typically bill their clients per minute. That said, it's hardly worth the effort and is just considered part of the operational overhead of an employee.

Metering hardware by the minute makes way more sense though, as is roughly correlates with wear. Things like electric scooters now charge per minute. But this is essentially the taxi model and this is obvious.

Partly because the whole WYSIWYG Website editor market is gone. ( At least that is what I think happened )

I mean even Microsoft didn't bother with Front-page after a while. After that was the blogging era. Movabletype or something perl.

I have been thinking if we will see WYSIWYG editor back, moving back the whole editing to client side. You simply upload a single page fully embedded HTML.

This has got to be simpler than whatever solution that is out there.
Yet another example of someone who doesn't understand the AGPL and how it doesn't work to protect your (or anyone else's) rights. It really is an utterly broken, non-free license. I've written about this in the past (read the topmost two replies too):

https://news.ycombinator.com/item?id=30044019

In fact, the author of this article claims to quote the AGPLv3:

> If you run a modified program on a server and let other users communicate with it there, your server must also allow them to download the source code corresponding to the modified version running there

But that is absolutely not the text of the license. You can check for yourself. That's not how the paragraph is worded at all. If that were the text of the license, it'd be a non-free EULA, since that wording imposes a restriction on usage, violating Freedom Zero.

Instead, the AGPL is a non-free copyright license because it violates Freedom 1, by instead imposing restrictions on modification, as I described in the analysis I linked above.

I really wish the FSF would stop pushing this nonsensical license and misleading everyone into thinking it does things it doesn't. Their PR around it absolutely does not reflect the actual wording and consequences of the license. It's deceptive and harmful to the free software ecosystem.
With the last update to repos in the org being 4 hours ago most no more than 5 contributors, that's about an order of magnitude less developers and development activity than just one Julia org (SciML) out of hundreds of orgs. For comparison, see https://github.com/SciML/ which saw 15 repos with changes by more than 15 developers in that time span. So by numbers, definitely not even close to the activity of just one part of Julia.

This is coming out now. The Russian propaganda has been operating on traditional media to large degree but much much worse on social media.

At exactly the same time, how many people have been banned on twitter lately for political opinions on what should happen to Putin? While they allow this russian propaganda?

Sure looks to me like Twitter is pro-putin.
I switched to Migadu yesterday after seeing some positive reviews here, and I’ve no complaints so far.
The problem is that Putin might be completely irrational, and therefore operating in unpredictable ways.

If we believe some of the news, the invasion effort looks poorly coordinated and very risky. There are some units stranded without fuel, some light mechanized units engaged big cities and got repelled, whereas others got destroyed on the roads without proper air cover.

Frankly, Russia has some very impressive military tech but the whole thing does not look well planned at all. It seems more like the product of a delusional leader and some incompetent high ranking officials. Getting into urban warfare, which is where this seems to be heading to will turn to big losses on his side. Reminds me of Croatia '91, but without the secession component. Jugoslav National Army threw shitloads of poorly motivated armor units and they got nowhere.
Oh the focus of the interview is very good.

It's Google's interview format after all (actually Microsoft's, but operating systems are hard as well).

The great big sleight of hand trick behind all of this is that the entire industry has copied the interview process of a single, extremely large, company.

And Google makes $$$ writing software for *extremely complex graphing and search algorithms*.

It's a great interview process. For Google.

For everyone else, it's holding up a great big sign that says "I'm a moron and I copied my homework assignment from Wikipedia."

Awesome tips! Great tactics and action items at the end.
The main way I see Ukraine winning is it continues like you said - Ukraine will lose infrastructure and key locations. But then it becomes guerilla warefare. At that point Ukraine has to outlast Putin or Putin's will to stay in Ukraine while he sees his military's morale and economy go down the drain.

All energy has externalities, fossil fuel externalities are much worse. Why object to the externalities of solar in particular here but not the externalities of what it replaces?

An honest comparison would only judge the externalities of solar in the light of the externalities of fossil fuels it is replacing, and not in isolation as you are doing.

While solar may use the grid as a giant battery, fossil fuels are using the atmosphere as a giant garbage dump. One of these is obviously much worse.
