Given the resulting output was "2x higher than expected", I'll wait patiently for any peer reviewed work on the subject and a replication (or improvement) of the results.

In the presentation they mentioned they couldn't reproduce the results immediately due to the containment imperfections -- at least that was my understanding.
If you look at the mass before of their fuel, 1 deuterium atom + 1 tritium atom:

2.01410177811 u + 3.01604928 u = 5.03015105811 u

vs the mass of the fusion products of 1 helium atom and 1 neutron:

4.002602 u + 1.008 u = 5.010602 u

You'll notice that even though we started with 5 neutrons and 2 protons and ended up with the same number there was some additional binding energy that is unaccounted for in the new configuration. This is the energy released by the fusion reaction via E = mc^2. Here we see the mass difference is:

5.03015105811 u - 5.010602 u = 0.01954905811 u

Converting that to energy you find that is 17.6 MeV. As you go up the periodic table fusing nuclei you will get less and less marginal energy until you get to iron where at that point fusion become net negative and fission is then takes over where breaking nuclei apart gains energy, marginally more as you go up the periodic table. That's why you want to fuse light particles and fission very heavy particles. It is also why there is so much iron as it is kind of the base state of both of these reactions.
I would say Canada is the furthest along (in the West) for true GenIV reactors.

They are taking an active approach:

https://nuclearsafety.gc.ca/eng/reactors/power-plants/pre-li...

Reactors like ISMR from Terrestrial Energy and SSR from Moltex that will operate at 500MW (rather then true 'small' reactors) are for more reasonable for scale.

They look like 'small' reactors but they pack quite a punch in comparison to PWR designs.

Any nation that just seriously commits to a single reactor design like this and plans to build 50 of them will do really well.

But I agree the same could be done with APR-1400 or AP1000.

So what? The idea of transparency on salaries is not a new one. Why would I want to do business with a company that won't even tell me how much they're offering for a job when asked? That just wastes people's time.

I don't care for this legalistic and disingenuous approach to business, it's an indicator that management is not going to be transparent with people who work there and is relying on information asymmetries rather than actually trying to build a team. Anyone acting like they don't know that potential hires have a strong interest in knowing what a job potentially pays is BSing you.

I’d argue that it’s a fine use of time to make murder illegal again every 15-20 years. That would help avoid the ridiculous “20 years in prison and a $1500 fine”-type laws that exist everywhere (made back when $1500 was a fortune).

In my state, detonating a “weapon of mass destruction” is punishable by life in prison, and/or a $50,000 fine.
Meh, the article is just hogwash and/or clickbait trash. They never define "innovation" and it seems like they're complaining that we value something other than massive tech companies that barely create jobs or value.

This is a stupid measure (number of patents), but it's better than whatever nothing is in that article. Seems like the EU is doing fine. The EU has issues, but "Europe not being good at innovating" is quite the leap that I doubt they can actually base in fact.

I wonder what else the author will suggest in their next article. Loosening labor regulations?

because digital assets have a fundamental difference with material ones.

I'm referring to how digital assets can be owned non-exclusively, i.e. we can both have the same data.

In contrast material (or physical) assets are exclusive. Either I have it xOR you do, we cannot both own the same thing.

Stocks (and other sophisticated goods) are interesting because they mean we each own a fraction of something, even when that object cannot actually be easily split. But notice how there's still a sense of exclusivity; the same stock cannot be owned by multiple people at the same time.

Do we actually know that for sure now? It would be hugely newsworthy if young voters finally actually showed up in large numbers. People have made this claim ever since Obama's first term and it's usually not actually panned out in the data.

(edited to add: I don't support banning TikTok. This is actually a free speech issue. I didn't like it when Trump did it by executive fiat and I don't like it now. If the content there is truly that corrosive, implement punitive measures short of a full ban. The bar has to be much higher than "I don't like it" for the government to fully censor something.)
That would be a valid argument if the only alternative to fusion was petroleum.
I don't know about that, but maybe they will try to create a new platform with their own expertise? There is clearly some public for that.
This legislation does not ban TikTok by name. It:

> [prohibits] all transactions from any social media company in, or under the influence of, China, Russia, and several other foreign countries of concern.

(After a quick read of the bill, it sounds like it may also ban VK. Although, it is already sanctioned.)
Great start.

The digital crack cocaine that TikTok is, was already under extensive investigation and will inevitably be either banned in the US on the grounds of national security or heavily fined to the point where they have to leave the US.

The fines for repeat offenders should also be in the billions, applying to all social networks worth over $1BN if it is enough for them to take user privacy seriously.

Title is click bait-y. This has next to nothing to do with kernel interfaces and is all about network tuning and encapsulation. Not sure why the authors went with the title as networking is interesting enough.

Also, the "slow" things about kernel interfaces (if you aren't doing IO which is nearly always the slowest thing) usually isn't a given syscall, it's the transition from user to kernel space and back. Lots of stuff going on such as flushing cache and buffers due to security concerns these days.
Another small step forwards towards sanity.

I was going to comment that this is a long term threat to Russia if they don't get with the program, but pleasantly suprised that the article already covered that angle.

As a sign of how things are moving in the right direction, I felt this might be stymied by the USA since they don't currently have a carbon price, but in fact it's been pushed forward because of the US introducing their own mostly very sensible legistlation. The momementum continues to build.
Why should I agree with this article of faith? The obstacles appear quite grave to me. Moreover, even reaching that Q doesn't mean we're there. That's a necessary, not sufficient, condition.

This, to me, is a really good signal of how well run a company is. After all, a company is merely a collection of people on whom its outcomes are entirely dependent. Thus, the single most important function a company can perform is hiring. If a company fails to recognize this or just does it incompetently, its probably a crappy company. Thus, slow responses == crappy company.

...a "breakthrough" that was incorrectly touted a fix for the pandemic, that would also be used to cure all disease, etc... (Again, not by the researchers themselves, but by pretty much everyone else.)

In the end, it definitely bought time for the elderly (and unhealthy), until Omicron actually changed the game.

If we had not got this particular mutation "winning ticket", given the disappointing efficiency of mRNA vaccines on infection and transmission, I'm unfortunately convinced that we would still have to show proof of a recent vaccination to get a coffee. (And since I'm in a particularly bad mood, let's not talk about the long term societal effects of mandates and restrictions and penalization of "not blindly trusting your government", which will reveberate.)

At least, we learnt that "maaaaybe it's worth testing our medecines on the half of humanity that has a functioning uterus" [1], which is a "breakthrough discovery" that almost arrived _after_ nuclear fusion.

What does "innovating" mean?

We're watching a lot of the last decades empty startups fall apart at the seam.

So many people have called these apps and services "innovation", yet they fail to solve a problem or make lives all that much easier.

"innovation" seems to have become a partial synonym for "fast and loose and not that effective".

It's not like the "wormhole" thing where what was produced isn't really what can plausibly be described as a wormhole. In this case, fusion really did happen, and the amount of energy produced by the fusion reaction was about half again what the energy put into the fusion reaction was.

That said, there are two pretty important caveats about how big a deal it is macroscopically:

1. In order to have useful fusion power, we'd need at least another order-of-magnitude or so energy out compared to energy in. Maybe, depending on how optimistic you are about the ability to capture that energy and efficiently feed energy in, closer to two orders of magnitude.

2. This is from an inertial confinement approach to fusion. Unlike the magnetic confinement approaches that we often hear about, this approach doesn't really create a continuously hot, spatially constrained bit of plasma that can then be used to heat things up -- it produces more like a small but intense explosion. There are real doubts about whether you can, even with very favorable energy-out ratios, industrialize that into an actual power plant. It's more challenging to harvest energy from an explosion than it is to harvest energy from a bunch of plasma flowing in a circle.

I don't mind the discussion, it is just more or less impossible to have when the premise is faulty. I can tell you exactly why Europeans think the US is better at innovation. It is because when Americans aren't satisfied with something they blame the US but still thinks the US is best country in the world. However when European aren't satisfied with something the blame Europe (or their country) and conclude that the US must be better. This has everything to do with US cultural influence.

> But yes, alcohol is harmful but I think smoking is even more so.

I think that's more due to the relative ease of tracking the harmful effects of smoking. I don't think the majority of harm caused by alcohol ends up on death certificates as "alcoholism" and there are much more non-fatal negative outcomes from alcohol.

It's not that difficult to track lung cancer deaths relative to smoking population and find the excess deaths but tracking road fatalities, spouses abused, kids dropped out of school and even the secondary effects like children of alcoholics not receiving help with schoolwork are much harder to track. Second hand smoke is bad but your chain smoking dad can still help you with your math homework.

(disclosure: American. I've dealt with a lot of European companies over the years. They're just as sharp as Americans if not more so.)

This is an excellent article by a European, especially its honesty when concentrating on Europe, which they're familiar with. The parts about how you can't get a mortgage if you're a startup founder, worrying about your pension (!), horrible consequences from bankruptcy, and tax prosecutions from the government are things that many Americans wouldn't think of. Going to a startup here is not seen as a life-risking decision.

How much of this has to do with LPs? From my cursory knowledge of EU VCs, they seem to managing much of their own capital, rather rather than investing on behalf of a large, driverse group of institutions and high-net-worth people. With the US based VCs (which probably have global LPs), they are looking for not just good returns, but also investments which maximize the efficient frontier of their portfolio. They explicitly are looking for non-correlated positive returns. Without LPs with that kind of mindset, I got to imagine the VCs would be much more risk-adverse.

> This result should be surprising if we think low tier universities have no signaling power.

To me, it's not at all surprising that "got the [equivalent of a] degree but didn't have the normal level of interaction with faculty" results in a vastly different outcome.

You're assuming that the credential itself is the signal. For regional economies in the US who hire primarily from regional universities, the credential often isn't the primary signal. They'll ask for a reference and actually talk with a faculty member listed.

Colleges and especially individual faculty have ties to major regional employers. Those employers understand that output is more variable (in large part because input in more variable). Other employers don't know anything about the institution at all and are likely to bin the app for any role that isn't eg low-pay or pure commission.

So the institution maintains relationships with alumni and others making hiring decisions at their "strategic" new grad employers, mostly regional small and medium sized companies. Frank assessments from trusted faculty play an important role in securing first placements. This is particularly true for (low-)paid internships, which are often the primary feeder for new grad positions.

If I know that the institution has mixed output and my phone call to the professor listed as a reference is basically "they completed some online modules but we didn't interact much", then I will probably pass.
