If we are getting to the point where W/m2 is an important win for nuclear, we are going to start to have serious problems with the rejected heat.

A fundamental limitation of thermal steam engines is that they can only ever be 50% efficient, and you have to dump that waste heat in order to maintain power.

Already, heat mitigation systems for some existing nuclear plants are starting to fail during heat waves as the climate warms. And these are expensive systems: at Diablo Canyon in California, it's cheaper to replace an entire, functioning reactor with renewables than it is to simply build a new cooling system.

Which is all to say that nuclear won't scale tremendously well unless we 1) figure out fusion, and 2) figure out direct conversion of energy to electricity rather than using steam turbines to mechanically drive a generator.

For the ultimate goal that many people have for nuclear, as a power source when not on earth, these sorts of advancements are also likely also necessary. Cooling in space is not a trivial matter.
There exists coal with more fissile energy, in the form of heavy isotopes such as thorium and uranium, than it has chemical energy, in the form of carbon-carbon bonds.

This is then burned in power plants, releasing the radioactive material into the atmosphere, and leaching it into groundwater from exposed piles of fly ash.
This topic got some momentum on here

two things. First though, please google before getting all dismissive.

1) YES smalltalk _has_ been ported to the JVM https://www.redline.st/ AND you can also run it in the GraalVM https://www.graalvm.org/

2) I'm pretty sure the initial JVM was a clone / extension of a Smalltalk VM. Having trouble googling the details, but while you may be having trouble getting it to work on your particular Windows install you might want to consider that you're possibly ignorant of the fact that the Smalltalk VM is not only one of the best available but battle tested over decades.

I would guess that what you're seeing is a particular windows issue that has nothing to do with the VM itself.
The 5% is quoted further in the article for overall grid waste. The per mile basis is purely there to compare why higher voltages for the Samer power lead to less waste.
The same GPS the US Government reserves the right to reduce the precision when they feel like it? Seems risky idea to assume they will never do this.
Probably a very long time, there are national security reasons to keep American airspace under constant radar coverage and radars get cheaper and better as time goes on.
> that have been cured for decades, like measles

Cured? Where?

The US had ~1,300 cases in 2019 and successfully put down the small outbreak. By September the cases were down to six that month and they stayed down. It was the worst outbreak in decades.

The EU had as many cases in 2019 - 13,500 - as the US did in the prior 20 years combined. That's ten times the figure the US had in 2019. In 2017 + 2018 Europe broadly had around 110,000 cases.

I think the US is very obviously doing excellent regarding measles.

I get the sense that the conflict the author describes is a problem in American culture, because most of us want to believe in a classless society, yet at the same time, class is everywhere.

I feel in many cultures it's far more explicit and tolerated. You know who your "betters" are. In America, you'd never acknowledge that.

I'm not saying that a rigid social hierarchy would be better -- but our approach to society is to try to downplay social hierarchies, while in some sense they're inescapable.
Snake stem cells used to create venom-producing organoids
I very recently had my ADSB fail while flying in a piper arrow. I think its probably good to have redundant systems in place, its a core to aviation to do that with instruments. Also, the military jams GPS rather frequently for exercises: https://www.thedrive.com/the-war-zone/17987/usaf-is-jamming-...
I agree with you. Arrogance often puts false premises - and I agree, can happen anywhere in the world.
To an extent, this sounds terrifying. The first thing that jumped to my mind is that GPS be jammed or spoofed. In fact, the U.S. military in its shift away from COIN to great power competition in possibly highly contested environments is training to have less reliance on GPS: https://www.zerohedge.com/news/2018-01-26/usaf-begins-massiv...

Radar can be jammed too, but I would guess the EM signature powerful enough to track. I don't know if GPS jammers would have that issue.

On a positive note, I think this would pave the way towards integrating commercial drone infrastructure into our airways a lot better!
Back in 2008 someone filed an issue titled "I hope Android will implement and support the USB host feature", a feature that has now long since been implemented.

Until the issue came back to life yesterday, the last comment was from January 2014. As of now there's 40 or so new comments; quite a few are responses to one person asking "So what did everybody accomplish in these 12 years? Graduate school? Get married? Buy a house? Had kids?".
More to the point, what even is "cultural value?" After Googling it, I found that it doesn't even seem to be a well defined phrase, much less a quantifiable concept.

Right. There isn't one game, there are infinitely many, and different people will have success at different games.

Hi there, always interested in personal finance services, but I'm having a hard time understanding from your website what sets Monarch apart from other apps?

How does it differ from YNAB (of which I am a big fan), for example? At first glance YNAB has all the same features shown on your website, and the "budget with ease" screenshot in particular could have been taken right from YNAB.

And what exactly does "The first all-in-one
personal finance platform" mean? What does it have that others don't?

Hope this doesn't come off as overly critical! I am really interested.
Yup. As an avid Mint user, nothing as happened to Mint as far as I care. The people working on Mint competitors are probably going to get a rude awakening. Sharing one's bank and brokerage passwords is not done lightly, after all.
Look up fly ash. Orders of magnitude more fly ash is produced than waste from nuclear plants, and it contains high concentrations of uranium and thorium.

While plants in e.g the US now captures most of it, huge quantities are still released into the air especially in countries with lower environmental standards.

But even places where it doesn't get released that just means having to deal with far more radioactive waste than nuclear plants produces.
I’d feel a lot more comfortable if they retained RADAR as a backup - why not have both?
"Custom CPU" seems like a bit of a stretch. They have ASIC people on staff (eg https://rocketreach.co/ya-chau-yang-email_61973123), but based on the fact that you can flash basically all their devices with OpenWRT (including those disc-shaped APs), I think the "ASIC" is just a conventional ARM or MIPS core with some peripherals geared toward hardware acceleration of common network tasks— switch routing, vlan tagging, etc.

This page talks about the specific features available for hardware offloading:

> Privacy of people who happen to live near the border? It seems unlikely that they are collecting much data on them, just because it's not useful to collect... I can see it being a real concern if they are collecting data on them.

I could easily see an agency argue that it needs to collect data on everyone near the border in order to track coyotes and others inside the country assisting with border crossings, etc.

After Snowden, it's hard to envision any agency with surveillance powers opting not to collect data for not being "useful". The justification is definitely there for those who are adamant about collecting the data.
I took flight school a few years ago, and had to learn to tune in non-directional radio beacons, and use VHF Omni-Directional Range tools for navigation. I wasn't allowed to use the GPS until I demonstrated mastery of the others.

Considering that, I suspect the aviation industry will keep both systems working for a surprisingly long time.
The most logical conclusion is of course that there is nothing, we mean nothing, have no soul in any way and our version of universe we have in our minds will simply cease to exist forever. Our dying is same as bacteria's dying, what kind of user experience do you expect for it afterwards?

But humans are anything but logical creatures, still rather primitive some would say (but we're trying!), so this isn't acceptable for many/most. Especially if one has been indoctrinated in one of many various religions du jour since birth, this idea becomes very hard to truly accept with all the consequences. Add high age and it becomes practically impossible.

Many people will mentally go to great lengths to avoid even considering this as a possible option. I don't blame them, for many life would lost any meaning (this I don't get, there is plenty of good regardless), and maybe adhering to morals of these days might be harder for them if there is no ultimate punishment. I personally find it liberating and am perfectly content with all aspects of this. Can't really explain rationally why though.
A radioactive fluoride salt might just be one of the most corrosive substances on the planet. Titanium might hold up a little longer but not by much.

Any material that can resist the corrosion will be bombarded by neutrons until it is transmuted into another material that can't, even with "slow" neutrons.
even before fire, organisms could only become more complex as the energy available to them increased

Heck, look at how the complexity of life increased as soon as mitochondria were invented, going from genomes measured in millions of base pairs for bacteria to billions for amoebas once cells were no longer caught in the square/cube trap of respirating over the cell wall.
Isn't low precision something like +/- 15 feet? For ATC, that seems more than good enough when they keep jets a mile+ apart. It just needs to be more precise than radar.
HIPAA regulates healthcare entities/providers, e.g. what info they can give out about a patient. Not journalists themselves.
You make a good point, but literally every fast food place near me has a 'Help Wanted' advertisement posted these days. I have the sense that they take anyone they can get, whereas in an industrializing society, the competition for those types of jobs (for recent agrarian -> city immigrants) would be pretty fierce.

Unemployment rate might be a better metric, but 'employment rate at food employee level or higher' would be the best I guess.
'No smoking gun': Bezos hacking report leaves cybersecurity experts with doubts
German anti-nuclear activists like to tout the percentage figure of renewables in the country, but that's not the right metric to look at : the coal+gas baseline is so bad in terms of CO2 emissions, that even in ideal conditions when wind production is 70%, German electricity's carbon intensity is still way higher than in France, Sweden or Iceland (

Coal causes 35.000 premature deaths in Europe every year, and 7 of the 10 most polluting industry sites on the continent are German lignite power plants.

Radar isn’t going away. This article talks as if ADS-B is replacing radar, which it’s not. It’s enhancing radar where radar coverage exists and providing coverage on traffic where radar coverage currently does not exist (usually lower altitudes away from major airports and over the ocean).

> I tried several; they're all either non-functional out of the box, or require significant time investment to even start approaching Google Analytics.

It's almost as if you need to be a software engineer and do actual software engineering, to responsibly use tools like analytics.

> I ended up going back to Google. It took the same amount of time to set up as when I initially set it up: around 2 minutes of adding the tracking code and uploading it.

So how much effort is the privacy of your visitors worth, then?

It sounds like deep down you know the right thing to do, which is a lot of work, but seeing everybody (in your bubble of technical peers) just as easily use Google Analytics, makes you feel like you're owed the difference to these profits.

Maybe there shouldn't be a 2-minute turnkey solution to analytics, because even if it's self-hosted, your next excuse is going to be that it requires a significant time effort to keep it secure and act responsibly with the data.

To add to that, it is also a problem that new remote teams have. When working with others who have been remote for years, we simply have learned how to use async communication for almost everything, and we just start up a slack call when we need to share a screen.

On the other hand, new remote teams are still trying to continue their habits from being in an office, so they want constant, easy communication. To me, this product sustains unwise habits more than it solves a problem.

But to each their own -- all teams are different, as are communications styles. I'm not going to say that products like this are bad ideas... just that the market is more narrow that people might believe.
> how would some typical frontend benefit from this

At ElixirConf I built a simple supervisor DOM tree model. When we are ready to implement it for real we're going to experiment with mapping the DOM to a supervisor. Each node being an element. This way events and rendering take place in each node in the supervisor tree. Rendering would be diff based and merged its way back up. Events would be captured as messages in the idiomatic Erlang/Elixir way.

This is all guess work right now and we don't yet know what will be practical vs what sounds good in theory.

However, we are dedicated to the idea that the programming model of the BEAM is one that complex client-side applications will benefit from over what JavaScript current offers.
And great thing is we all will get to know the answer :D
Radar has been jammed in the past by accident, since home routers now operate on the same band. See https://arstechnica.com/information-technology/2015/09/fcc-a... . 5G coming in doesn't improve matters. GPS is actually reserved, so there's going to be a lot less accidental interference.

I can’t read the article (paywalled), but I would expect primary radar isn’t going anywhere around airports.

We still have it, and our commercial planes have been required to have ADS-B transponders here for more than a decade. This is just for en-route tracking.

One thing missing for me is if reading print books is different from ebooks and read along books? I’m legally blind so I spend a majority of my reading time on some kind of electronic device because I can zoom or enlarge text. Articles like this don’t differentiate whether the medium or the activity is the problem so I’m left wondering if reading with my kid on an iPad is worse than a print book or not and whether having someone else read for us together is different than if I read to her myself. I spent so much of my youth playing video games that I’m not concerned it’ll be a huge factor in her life but it would be great to be able to be better informed about the pros and cons of each approach.
It's also worth adding that this wording makes it extend beyond the US borders. If the US Constitution granted rights to individuals, it would only apply to individuals under the US Constitution. Instead, it makes a blanket assumption that the freedom of speech exists, and that while other governments may restrict it, Congress may not. For example, overseas funding for HIV/AIDS may not be conditional on recipients having a strict anti-prostitution policy, as that would violate the free speech of the recipients[1].

> A graveyard orbit sounds like it will be flying around up their indefinitely as high speed shrapnel. Does anyone know why they would choose this instead of destroying it on re-entry?

Because the ∆v required to re-enter the atmosphere is significantly higher than that required to leave geosynchronous orbit for a higher graveyard orbit.

But yes, ultimately it will remain up there as "high speed shrapnel" - which is not an ideal situation, and continuing to treat disposal as we have may put us in a situation where these orbits become so full of high speed garbage that they are unusable. As a species, we need to do more work on cleaning up our space garbage before it's too late.

So there are more hoards of cash in the world! Cool! I bet part of why rich peeps feel like this is realistically doable now is because of technology. They have a Nest or something and a smartphone and because they can access cameras at their house anytime they feel like they are more secure.

But what could happen is that an enterprising h4x0r (possibly one who works for one of these IoT companies) realizes that even better than peaking at dick picks, you could have a comprehensive catalog of who is keeping this cash and where. You could then either sell the data (cheap at first, expensive later) or act on it yourself.

My point is that if you're loaded and hiding cash on-site, you probably don't want a normal commercial IoT system. You probably want something built for you by the suitably paranoid people on websites like this one! (I suppose that's another security risk, though.)

What about communism makes a source untrustworthy?
I spent almost two years on a project of such a nature at a ginormous company in the low 8 figure budget that changed on an almost daily basis and was killed at the last second - in order to start an even larger and looser project, while simultaneously starting a second similar project in insane fashion. Coordination is mostly a hostile battle between high level execs, with lots of promises of this time it will be different and never is. I always question decisions if I can but often you get no access from a technical level to the people deciding (and battling about) what is to be done, so often you can only deal with lower level decisions in your area. Sometimes you win a little but often your winnings are lost in a sea of terrible decision noise.

Then again I've been in tiny companies with low 6 figure budgets for projects and you still wind up powerless to ask the right questions.

Sometimes you have to settle on getting your part of a giant project right and sigh your way through the rest.
