The trick is that to compete in that segment you need to nail the gameplay. Nailing the gameplay is something much harder to pin down and understand than whether it looks pretty. While itâ(TM)s much cheeper to release a good game in this segment *if* you nail the good game part, itâ(TM)s very unreliable as a source of income if you havenâ(TM)t nailed it yet.

I mean, youâ(TM)re right that itâ(TM)s not here, but this is probably the safest fusion bet there is. We know really quite well how well Tokamaks scale. We have loads of examples of them, and we can predict really quite accurately how theyâ(TM)ll perform at this point. We know that there power density can be described as

(Beta_N ^ 2 R B^4) / q_* ^ 2

Beta_N and q_* are design features of the geometry etc of the tokamak, we know whatâ(TM)s achievable, and have plenty of examples already. That leaves you with two levers to pull - R (the major radius), and B (the magnetic field strength). When we first started building tokamaks we used copper for the magnets, we moved on to super conductors and increased the magnetic field strength, and then hit a wall. So that left us with only one lever to pull - major radius. Thatâ(TM)s why when you look at ITER, you see this *giant* device that costs billions. We know exactly what we need to do to break even - we need to increase the radius, and the power density will go up linearly, and weâ(TM)ll get there.

The thing is, in relatively recent years weâ(TM)ve got good at producing a bunch of new superconductors. We can now make REBCO tapes of significant length. The nice thing about REBCO, aside from not needing to be cooled as much as traditional superconductors, they can stand much higher magnetic field strength before they give up on superconducting. CFSâ(TM)s approach here is simple - build a device the size of existing tokamaks that weâ(TM)ve built at universities and research centres, but build it with REBCO superconducting magnets. That gets you double the field strength, which gives you 16 times the power density. JET already got to a Q factor of 0.72. And that was with copper magnets. Itâ(TM)s really really clear that SPARC *will* get to a burning plasma, because it can be more than 16 times as efficient as JET.

Thereâ(TM)s basically one question for whether ARC will work or not. When (not if) SPARC achieves a burning plasma, will all our techniques and algorithms for controlling the plasma still work, or will the new regime mean we have to completely re-learn how to do all of that stuff.

Long story short, can it fail? Yes - itâ(TM)s not done it yet, of course it can. Is it likely to? Not very. The physics is pretty well nailed down for most of this stuff.

Yes, and that means that mastodons protocol is fundamentally incompatible with states that implement this kind of draconian law. Thatâ(TM)s what I mean about the court just saying âoeweâ(TM)ll change your softwareâ. They wonâ(TM)t say âoewell okay, since you explained how your protocol works and how other people can run servers without verification you get to ignore the lawâ, theyâ(TM)ll say âoewell donâ(TM)t write and use software that does that if that violates the law.â I think mastodon would have more success by going on an offensive. Sue a major email provider for not verifying the age of people theyâ(TM)re sending and receiving emails from. Demonstrate that laws like this effectively outlaw email.

Comment Re: it's not the drugs (Score 1) 83

Itâ(TM)s well understood that psychostimulants donâ(TM)t have the same effect on ADHD sufferers as they do on neurotypicals. On ADHD sufferers the increased dopamine stimulates their default mode network which wakes it up enough to be able to get control over all the different things going on in the brain. Thus ADHD sufferers report that the stimulants calm them down. Itâ(TM)s also common for ADHD sufferers to report other substances that cause dopamine release like coffee and alcohol as helping in the same way. Neurotypicals meanwhile have enough dopamine for their default mode network to be in control anyway. The extra dopamine goes towards stimulating other areas of the brain, resulting in more things going on in their head, not fewer.

At least here in the UK, the diagnosis rate is around 1-2% of population. Given that the fairly well recorded in the literature rate in the general population is 5ish%, itâ(TM)s quite clear that either the UK has exceptionally outlying genetics, despite having lots of immigrant population; or weâ(TM)re actually chronically underdiagnosing. The idea that weâ(TM)re overdiagnosing it just comes from the same place that fat shaming, racism, homophobia etc come from. We all like to feel superior to other people. If itâ(TM)s ADHD, then we canâ(TM)t say theyâ(TM)re just lazy assholes who canâ(TM)t control their emotions, and we canâ(TM)t feel superior to them.

1) no, and 2) no.

If youâ(TM)re taking a dose that causes those issues then youâ(TM)re taking too much. The aim is for a dose that gives you a dopamine boost before any of those effects kick in.

No, itâ(TM)s not the only option. Another option is dopamine agonists, like Pramipexole. Yet another thatâ(TM)s coming online soon is SNDRIs.
