First wall problems compounded by geometric constraints, fueling, magnetic & corresponding mechanical complexities, particularly over long periods of time where material fatigue sets in due to coils applying heavy, dynamic loading.. there's a lot against tokamaks.

They seem to impress people, and we could all use novel research into MHD. But @Blackdoomax@sh.itjust.works is kind of correct.

I'd say before, read up on that trashbag Goldwater for example. And he was their voice of sanity!

I like taking care of kids, pets and eating edibles just fine, thanks.

All of what you're saying seems correct. I think this is more of a meta discussion, on how (in this case) retries, even with exponential back off, aren't a solution by themselves when you look at the system overall. There are interesting hidden caveats to any common solutions, this is one I personally wasn't aware of.

Practically, adding a timeout budget so that the clients themselves just error out (forcing a manual refresh) sorta accomplishes the same as what you're positing.

Is there anything like this in the US? Seems like a fun group.

Hmm... I'd say that was an obvious example to cause the situation, the real point was exposing the more subtle problems with feedback loops.

What happens if the server in question was at 80% capacity, and due to hardware faults, that leads to 100% utilization? Can you reconfigure your services if there's a cascading overload through enough of the system without actually adding to the system load? What do you do about the fact that these loops gets ever more powerful and sudden the larger the system?

The author seemed to be suggesting that we carefully consider how to avoid open feedback loops, and build stability in. This article clued me in that stability problems can be borne from "industry standard" advice if you don't carefully think about it.

Google Pay alternative?

Hey there, I'm looking for an alternative to Google pay that'll allow me to use NFC payments etc. Thoughts?

I don't have a Google account, nor am I interested in opening one.

I don't really care. My dick works great, I wouldn't do this to my kids but my parents trusted the doctor. I still love my parents anyway.

E: also, this illustrated girl looks really weird, and this is a really weird conversation. Real women do not look like this, and I wouldn't get naked in front of a girl who looked like this. Eeesh.

Jesus, it went from $14bn to over $30bn in cost overruns? That's embarrassing.

No, I still think bud is safer.

Sigh, here we go with the shittyness.

Hey everyone.

I built an mk3s+ from its kit form successfully, tested a few PLA prints with the stock 0.4 nozzle.

I've set prusaslicer to use a 0.6 nozzle now that I've upgraded, and am using PETG. Prints look pretty bad, in spite of calibrating z-offset etc.

If you were doing something like this for the first time, what would your setup steps be like?

To be specific, using a diamondback 0.6 nozzle, matterhackers PETG at 235c.

Issues I'm seeing are a really bad loss of detail, lots of stringing, etc.

eta: added a photo of a moderately post-processed part. Notice how rough the top surface looks, there's a disconnect between perimeter loops, etc.
