The new generation of Russian fast neutron reactors use lead and lead-bismuth as coolant, not sodium anymore. They are not proper breeders, as I understood it.

It is not an equilibrium since enrichening, so yes.

Thorium fuel cycle is useful for weapon production. Germany also abandoned thorium despite no interest in weapon production.

One is primary literature, the other is mass media discussion. Complementary and more visibility for an underappreciated topic vs climate.

Some of the new Russian reactor types are designed to burn away dangerous hot actinides. MSR need onboard fuel processing to continue to operate anyway.

I am in this picture and I do not like it.

Too bad we do not know which exactly thorium salt mixes they are using, what the materials facing the molten salt at high neutron fluxes are and how they fare long term, whether they use on-site constant or batched fuel reprocessing, whether they kickstarted the reactor with enrichened uranium or reactor-grade plutonium waste and other such questions.

US experiments were broken off because of materials corrosion problem.

IPv6 is really widespread.

In a sense. There was a varying threshold technical bareer of entry to BBS, ARPANET/Internet, email, Usenet (uucp over dialup for early adopters), mailing lists, forums and communities like Hacker News, even early Reddit and Digg.

Perspiration does not cool down at lethal wetbulb so wetting the body with ambient temperature water does not help since there is no evaporation enthalpy. Forced convection air buys you almost nothing. Immersion in ambient temperature water, especially agitated, buys you a few degrees higher tolerance due to its higher heat capacity.

Retreating underground into previously prepared subterraneous shelters would help. Starting digging too late will just give you a heat stroke from physical exertion.

Realistically, lethal wet bulb spell of a few days in an unprotected population is a mass casualty event. Given that grid failure is likely under the circumstances, the size of the unprotected population is larger than many expect.

The latter doesn't work for lethal wet bulb temperatures.

Heh.

Another good reason to stick with Debian though.

So what do you wear to survive lethal wet bulb temperatures for a couple of days? As a rural third worlder with no access to power or air conditioned spaces?

Linux kernel? Where?

Assuming you mean distro, where is it in Debian?

If I want AI I can always install llama or similar locally.

They are probably going to offset it with buying greenwashed indulgences.

Whether NFC payments work seems very much dependent on what your bank app is allowing. Some banks in the EU have no issues, so you should check what particular payment system you want to use.

In general, chances are low. Some people use smartwatches as a workaround.

I don't use smartwatches nor NFC payments with smartdevices. My bank card allows NFC payments directly.

I've been online since early 1990s and this is my repeated empirical experience that communities with a technical entry threshold self-select for technical users initially.

Most social network users are already hopelessly confused by the concept of federation and need to pick up an instance.

LOL
