@louis I started out with uninterned symbols to avoid interning, but nowadays I prefer the interned for less extra syntax. I think the overhead of interning a handful of symbols is negligible.Using strings can break with nonstandard reader cases (and doesn't look pretty to me). Keywords combine extra syntax (compared to interned symbol) with extra interning (compared to uninterned symbol).

@galdor Any particular reason why you're basing this on CLtL2 instead of the ANSI Spec?

@galdor Well yes, since the HyperSpec is available at several places, I'm primarily just using that, skipping the checking-to-be-sure.

@hanshuebner @louis Interesting. May I ask: how do you manage the stored procedure code? Is it in source control? What does bootstrapping and deployment look like?

@galdor Usually you'd use digit-char-p for characters. http://clhs.lisp.se/Body/f_digi_1.htm#digit-char-p

@Sweetshark @kravietz No, solar is not at all better at matching demand. You can't just move the clouds aside when you need it. Nuclear can just do normal load following.Volatile sources such as solar and wind can only provide 40% of direct electricity demand, the rest must either go through storage or come from »backup«.Solar and wind are a useful addition to our decarbonization efforts. Nuclear energy is not in competition to them, but to the other 60%, where it replaces fossils.

@Sweetshark @kravietz Nuclear load following in practice, example.

@Sweetshark @kravietz Also, France does it all the time, that's why their capacity factor is so low.

@Sweetshark @kravietz I didn't write »renewable«, I wrote specifically about solar and wind (»volatiles« as some call it).(Whether biomass is »renewable« is debatable, but it is definitely not climate friendly, by the way.)Yes, you can nominally have a larger part than 40% (yes, a very rough approximation) in Germany IF you can use the entire European grid as a sink/source as needed (and if your neighbours don't do the same…). But that's running into diminishing returns quickly.

@kravietz It's probably easier than storming the ukrainian ones.

@collectifission I don't see how having a vertically integrated direct and complete competitor is necessary for sanctions against Rosatom. Just sanction them.And of course, support »western« nuclear industries, mostly by removing purely political obstacles.

@publius @collectifission Sanctions work, even if they are not perfect. They increase at least hassle and costs. And you can put pressure on other countries too. Non-perfection is no reason against them.I believe that tech transfer and local participation is important for sustainability and resilience, but of course, if a country only wants a turnkey black box, that market should be served too. So, I agree with your out-compete point.

@collectifission I think the reporting could be a bit less sensational, as if this success was in any way unexpected.But anyway, it's nice to have another price point for decommissioning, which seems quite affordable.

@collectifission They just need to show Germany as a bad example. That should convince anyone.

@collectifission As usual, my first reaction is: don't let the promise of even better future nuclear technology distract you from the fact that current nuclear technology is perfectly fine and probably a better (and more sustainable) bet now than anything else.

@publius @collectifission Yes, I think it's right to take any small concession. The alternative would mean that people turn around 180° all at once, and that's much harder.

@collectifission I've seen some solar guy explaining that the inverters that create alternating current from solar (and wind, although that's more complicated) are very good at /following/ the phase and frequency of the grid, but in that, they /amplify/ disturbances. Turbines (hydro, nuclear, gas etc.) on the other hand have a lot of inertia, /dampening/ disturbances.So, »stability« is not just about reliability, but also about inertia — »rotating mass«, as some call it.

@hkrn It sounds like they are citing from an interview. Anyone know the original source?

@jackdaniel Wasn't there a library virtually implementing (i. e. no GUI) this, I think called "cells"?
