Is the problem that they won't approve it, or that the technology isn't yet mature enough for production-scale reactors? And if it's just a mature of (presumably political) regulatory resistance, is that also true in France, in Russia, in China, in India?

That's the problem with all these "We'd have cheap safe nuclear power if it wasn't for those stupid treehuggers" arguments - if nobody is doing it, not even in countries that are pretty reckless and unregulated like China, maybe the problem isn't regulation.

> The choice is a stark one: either invest in technologies and infrastructure to decrease CO2 production, or give future generations the gift of a dead planet.

The science says otherwise. Did you know that for most of Earth's evolutionary history the climate was far, far warmer with higher CO2 concentrations than today? Global warming has lots of negative ramifications, but it is not going to create a "dead planet."

Spreading outright falsehoods doesn't help things.

I agree that "increase diversity" is a rather obtuse meta argument, and using it implicitly argues that there are not other significant discrimination issues facing these groups. Maybe it is a better argument to make in certain settings though. For example, a company wouldn't want to admit to having discriminatory biases in hiring, so "increase diversity" is a much more palatable objective.

The more honest, less PR answer is that people still discriminate on huge range of factors. Race and Gender are just the most obvious and egregious.

That is really disgusting that they are verifying dead people. Even though his estate authorized it, seems like a betrayal of his legacy to allow someone else to present their speech from him.

I hope the US soon passes legislation banning impersonation of the dead unless they explicitly authorized that use while alive.

Similarly Erica Garner's account is verified and was taken over by one of her friends after her death. Some controversy after account tweeted things in direct contradiction to what Garner said while alive.

Misleading. The article says things like the F-35 is "designed to be undetectable by radar."

Nothing is designed to be undetectable by "radar." "Stealth" aircraft are designed to be "invisible" (low-observable, really) in one or more radar bands. Once you get outside those EM bands, the aircraft is obviously detectable (e.g., you can see it because your eye doesn't operate in the X band).
It is relevant for this forum, especially since the project is opensource.
I wonder if these F35s had external fuel tanks attached, for the long flight back home?
This isn't strictly just about a weakness in the F-35's radar resistance, but that the whole concept of "stealth" aircraft may be limited in the future thanks to ever increasing computation power and clever usage of existing radio waves (making effective, passive, "radar" that cannot be easily overcome). But as the article points out, this cannot yet be used for guided missiles, and is very early tech regardless.

I suspect the future won't be "super weapons" like the F-35, but instead just "mass" weapons like tens of weaponized drones. Where the mission isn't to be invisible but to simply overwhelming enemy defenses (essentially the World War I strategy, but without the massive numbers of dead soldiers).

PS - The people pointing out that the F-35 had radar reflective disks added didn't seem to have understand the article (or technology). This is using entirely different methods to detect the aircraft, not radar waves, so that's irrelevant. The F-35 could be broadcasting a transponder, and it wouldn't undercut the technology discussed.
Goes a long with a story I heard last year concerning the presence of a German radar and electronics company at the ILA. The story goes that Lockheed didn't want to fly the F-35 as long as the most advanced radar was on premises. After the radar was moved the F-35 cleared. Also, the radar was set up further away. And the F-35 successfully located. (I wasn't there, so that is a second hand story).

EDIT: The Spiegel reports more or less the same story, occurred in Aptil 2018. The radar comes from Hensoldt, a former Airbus subsidiary.

And, as already stated in another comment, it was passive radar in the sense it took existing signals and analyzed them and their absence.

EDIT 2: Yeah, submitted article reports the same story... Lazy me...

I think this is true of their men's clothing, but not necessarily their women's. My girlfriend's Uniqlo clothes have not lasted as long as mine and they are visibly more cheaply made. For example, one trip, we bought the same coat at the same price, but where mine used three lines of stitching, hers used only two. Her coat started losing down almost immediately. I just pulled the coat out of the closet to wear again this year, but hers only lasted two seasons.

> Their “general learning” tech doesn’t even generalize to barely modified variants of the original games it has claimed to master. I call bullshit.

But the point I was making is precisely that the "general learning" tech is in fact somewhat general. AlphaGo and certainly AlphaZero's learning tech generalises to Go, chess, and a few other games. That's relatively general in the domain of board games, in my humble opinion.

The reason this isn't close to AGI is because it's not the agent doing the learning, and so while a relatively general learning algorithm produces the agent, the agent itself is not general even in the field of board games.
Ask HN: How to get started reengineering a legacy monolith
Hi,

I have been asker to reengineer a legacy monolith. It has over a million LOC and is based on C. The application is entirely new to me. Any thoughts on how I can get started? Would love to hear any gotchas too.
Your storage should be separated from the worker nodes. Unless you have some hyper-converged setup, then you make the deliberate choice that your node became special. (sorry for using the term hyper-converged)
Most people probably wouldn't choose that just because the option would now be available. They might also fear the now legal extra-judicial punishment available to friends/families of victims.

I know a lot more people would park in handicap spaces if the fines were made optional. Speeding is another good example where people literally slow down when they see someone capable of punishing them.
That's also true in the US. We have way more trees today than we did 100 years ago. https://www.goodnewsnetwork.org/america-trees-now-century-ag...
Yes, if the countries deploying the F-35 have any sense at all, they will install equipment to make the aircraft trackable on all air show and most training flights, so that potential adversaries can’t accurately assess their ability to track it in full stealth operation.
Musk broke the law with anti-union tweet
They seem to strip out all but one narrative, but thats irregardless of astroturf.
I recall that in at least one case an F-35 used for an airshow demonstration had visible deterioration of the stealth material forward of its canopy. It seems that the low-observable systems used by the F-35 are very maintenance-intensive and that the jets used for shows may not be in combat-ready condition.

(or, if you prefer, maybe the jets used for demonstrations are intentionally damaged in visible ways so that there is a convenient excuse for the ease of detecting them on radar)

edit: I was thinking of the F-22, see comments below for a source. But similar considerations probably apply to the F-35.
Oh I know. I was just having a giggle about “smart all the things”.

The radio control street lights have mainly been a success. As I say only one failure in my area that I know of but when they do fail, it fails spectacularly.
I agree with this. The choice of advisor makes a huge difference in your PhD experience. If you get along well with your advisor, have mutual respect, and are working on interesting topics, getting a PhD is an exhilarating experience.

TL;DR: Pick an advisor you're excited about.

The funny thing is, that even people that make these lifestyle choices can be hypocrites in their own right.

They buy gas guzzling cars. They stay in huge houses with massive heating bills. They endorse sparse suburban housing too.

I am also not a huge fan of those advocating for complete veganism in the name of climate change. (not those who make an individual choice mind you. That I respect). Ingredients like fish sauce, worcestershire and the like have trace contributions to climate change, and make it incredibly difficult to cook certain cuisines without. Fish, chicken and to an extent milk products make minuscule contributions to climate change and are still lumped together with red meat.

Some peer review & published studies [1][2] believe that total US veganism will lead to only a 2% decrease in GHG emissions in the US.

[1] https://www.pnas.org/content/114/48/E10301
[2] https://theconversation.com/yes-eating-meat-affects-the-envi...

IMO, the most effective move would be to move to low meat cuisines. Stir frys, curries, brothy soups and the like use a lot less meat than burgers or steak. Some of those work perfectly fine with zero meat (minus meat derived spices/sauces). Feel like the current trend with veganism is a stop gap until we figure out hoew to lag grow our meat anyways.
Yeah, I keep seeing this a lot, I generally don't care that a tool is 'written in X'.

That doesn't explain how it beat a number of other technologies at the time -- including well established ones, like Perl.

I think you are thinking of these recent photos of an F-22: https://www.thedrive.com/the-war-zone/29218/these-images-of-...

However you're no doubt correct that radar absorbant materials is high maintenance on any aircraft.
This. It's common knowledge that F-35 and F-22 both fly with markers to ping on radar. Additionally, the fact that the F-35 was squawking their ADS-B indicates that they were not flying in operational mode.
How many engineers does WeWork actually employ though? From everything I've read on here they're not really a tech company. I can't imagine that, even if it all goes up in flames, there will be many SWEs looking for new jobs from this.

Uber is another story. They've got a sizeable engineering force.
Community starts with good people; creates good content; attracts more people; that new people tends to average; contents tends to average; new people tends even more to average; contents quality becomes average; community isn't good anymore.

The cycle certainly didn't start with groups over a computer network, but I think it's very unlikely that it started before written texts. So there's ~8k years window there. It's not literally timeless, but does feel like so.

Rust is far from being "an obscure programming language", and I'm pretty sure there are people here on HN that may find useful to browse the source code of a real world application in Rust (and who don't give a shit about the software per se).

Such comment would have made sense if this software was promoted in a more general board/website, but HN audience is mostly compound by developers, so technical aspects matter. On top of that, it also gives an idea about the popularity of a programming language.

If it's the same story as most other fields, the related jobs available require either:

1) No phd, because those either command a high salary, or are likely to jump ship for higher pay as soon as they meet qualification 2:

2) A phd and previous experience, because the job can't be trusted to someone fresh out of school without practical experience.

As far as I can tell, Turin is the only one still pursuing this theory, and he hasn't made a lot of headway. About five years ago he was trying to prove his theory by producing molecules with heavy hydrogen, which would smell different by his theory and the same under conventional theory, and the results were inconclusive. He seems to have moved on to other areas.

His theory has a fascinating way of explaining what it means for novel smells to be judged similar, but nobody can find a mechanism that would allow it to work. That's not proof that it doesn't work that way, but the conventional theory is proving very productive in research, and his hasn't.

The radar people claim that the "markers" intended for microwave frequencies would make no difference to passive radar. That seems quite believable as passive radar uses things like commercial VHF radio transmitters as emitters. The frequencies involved are vastly different. The features are simply too small to cause much of a reflection at VHF.
Wow what a huge rise and fall in the past few weeks! What I don't understand is how the S-1 filing ever saw the light of day? How could nobody reviewing that see any of the red flags that were obvious?

Even if the entire planet converted over to electric vehicles you would still have to build / maintain roadways which too often are made of asphalt, which is full of polycyclic aromatic hydrocarbons (PAHs). These chemicals are also found where ever combustion occurs and are highly linked to cancer and cardiovascular disease.Everytime it rains guess where asphalt oils and compounds go ? Wear of rubber tires also contribute to microplastics/microrubber particles that never biodegrade, much of which washes down into the oceans.

Often it’s only through interaction that I can tell if people are making the effort or not. Does SO need more people editing and doing triage? A different interface that bridges the gap between Q&A and wiki? I don’t know.

I think it matters a lot more to know the reviewer than to understand what portion of critics like/dislike a thing, and I find that aggregators are accurate only when signaling the same scores that the majority already expects before they check the aggregator.

Every reviewer has a consistent voice and set of tastes, and it matters if a reviewer you generally agree with falls into the positive 40/300 on one movie or the negative 260/300 on another.

Maybe your favorite media reviewer Bob Obert can't stand historical drama movies or mockumentary series, or the Meater blog you read is consistently biased toward giving BBQ joints high scores. When you see Obert give a The Office episode a 4/5 that is mediocre by Generic Yahoo Contributor standards, or Meater feature a seitan food truck in Portland while being critical of an artisan brisket restaurant, you're going to value those reviews much more over the majority of others.
