It's worth distinguishing ITER from fusion research as a whole. While it's an interesting project, I doubt it's going to be first to market for actual power generation. Its design is fighting some pretty nasty scaling laws th

If anyone's not already aware of it, the SPARC/ARC reactor work spun out of MIT looks pretty promising on shorter timescales than ITER: https://www.youtube.com/watch?v=KkpqA8yG9T4 https://www.youtube.co

The 'neurodivergent' umbrella covers a much wider set of things than just 'degree to which the person is perceived to be a jerk'. The perception of jerkitude is usually a side effect of something else complicated. For ex

I've often wondered- are there solid studies on responses to stimulant medications varying over different groups? It's definitely true that there is wide individual variance (modafinil does nothing but disrupt my sleep and make me

It doesn't actually require awe-inspiring commitment and dramatic personal sacrifice, and such grand gestures would likely end up unsustainable. I just suspect that the ideas themselves will tend to sound really hoity toity and holier

Yup, started writing my response before I saw yours, definitely a different point. I do think that the implied burden is still alienating in a sense and that's what motivated my post (the philosophy can just feel really bad in some way

I'm not yrimaxi, and I'm very much in the EA camp, but I suspect a lot of people bounce off the implication that there isn't really such a thing as supererogation. A lot of EA messaging tries to work around this by trying to

I think there might be a couple of things going on here: 1. Slightly differing definitions of what constitutes 'angry', and 2. Dramatically varying subjective experiences of anger. For example, in the case of #1, I usually separat

Games that are aiming more for a "cinematic narrative experience" might be perfectly fine with a few 33ms frames of latency, and a total input latency far exceeding 100ms. Competitive twitchy games will tend to be more aggressive.

If I'm not mistaken, that was research in mice. Mice are nocturnal and do not likely have the same entrainment patterns with respect to blue (sky) light. There are still valuable things that can be learned from that kind of research, b

True enough, but starting at 9:00 AM instead of 7:30 AM still leaves plenty of time for that. It wouldn't have been enough for me , but an extra hour and half of sleep would have been way better than nothing. I also suspect that start

The fact _you choose_ to stay up all night hacking on things does not matter in the hours of school operation. That's pretty frustrating to read. I was sleep deprived enough to sleep 15 hours a day on the weekends during high school,

Having both written physics engines and worked with GPUs extensively (including GPU physics simulation), I would be really hesitant to go GPU-first unless there was a very specific use case in mind. There's no doubt that GPUs have the

While island based parallelism is doable and works reasonably well for many workloads, it's possible to dynamically batch constraints based on their involved bodies such that no constraints in a given batch share the same bodies. All c

Given the timescales that humans operate on, it would be incredibly strange for us to reproduce into extinction. As far as direct effects, an unmitigated exponential growth trend would eventually result in widespread famine and other resour

This line of reasoning has always felt incredibly bleak. There's an implied lack of preference for continued experience which can be repurposed to regard suicide indifferently. It's difficult to take a consistent position that hol

It's a sleep disorder- one that I probably would have been able to detect and mitigate decades earlier if I had the information I collect now (and the knowledge I have now). "Quantified self" style tracking usually isn't

Maybe not a bad first approximation, but this approach would suggest I should be asleep always... Sometimes information can be handy, even if all you're getting is an automated way of collecting information you already had access to.

With the gradual accumulation of parallel projects, I've recently adopted a constantly-jump-around approach to development to keep everything braincached. About four projects in flight that I can talk about at the moment: 1) Neural app

On the software side of things, the good news is that the combination of a decent conservative advancement detection scheme and speculative contacts can get you down to microsecond tier fidelity pretty cheaply. (Incidentally, this specific

While the lack of full rate 256-wide operations was quite noticeable, I was expecting it- the cliff that caught me by surprise was something else: certain kinds of inter-CCX communication seem to be catastrophic for performance. The rest of

On the CPU tooling side of things, I was planning to buy into another Intel CPU for my workstation for the same reasons- until I ran into some 50%+ performance cliffs in Zen 1. (I suspect Zen 2 addresses some of these.) I'll still need

Both of those things are potential issues, yes. And they should be kept in mind so the future can be less bad. But they are not unsolvable problems, nor do they imply that aging is better than agelessness. They just imply we have to work ha

Agelessness might cause some social problems, but if the choice is between "everyone dying" and "needing societal innovation to avoid stagnation", it's hardly a choice at all. In an alternate Earth where humans neve

Yup- if you have control over the entire deployment, more reasonable options open up. For my purposes, CUDA isn't really an option due to needing to run simulations on both servers and unknown clients (ideally with a single codebase),
