No, there will absolutely be a fight.

The moment Trump fully realizes how incredibly he's lost, he will immediate switch to military threats to save face.

He has no choice, it's one thing if the American economy collapses, but his ego is at stake here!

I'm rooting for the EU. The only ones here who aren't being dicks.

It's not quite that.

The dixiecrats took over, the ones who are still enraged we took away Jim crow.

They have given the GOP a rabid base of racists who will support any economics because they don't know what the word means.

I'm gonna have to donate then.

It pushes stuff when they're really really cold, so for instance init services and libs that have basically never been touched since boot but still technically need to be in memory.

They might have been pushed out because the page cache thought it had something more interesting, or if you have VMs, because the system wanted to make some huge pages.

It's good, but be aware you want to stick to LTS kernels or at least don't upgrade casually.

Arch is the worst for this, ubuntu and debian are better but still get hit.

Hit this recently on an arch build, switched to kernel-lts and it worked, but basically once every year or so the abi breaks and zfs is dead for 3-6 months on github.com/torvalds/linux@master. Just FYI.

Thank you for giving me hope for the future.

FYI, zfs is pretty fucking fragile, it breaks a lot, especially if you like to keep your kernel up to date. The kernel abi is just unstable and it takes months to catch up.

Which is part of why I don't trust zfs on root.

Worst case you can sometimes recover with zfs-fuse.

China has the pbr in production as modular reactors.

When the reactor temperature rises, the atoms in the fuel move rapidly, causing Doppler broadening. The fuel then experiences a wider range of neutron speeds. Uranium-238, which forms the bulk of the uranium, is much more likely to absorb fast or epithermal neutrons at higher temperatures. This reduces the number of neutrons available to cause fission, and reduces power. Doppler broadening therefore creates a negative feedback: as fuel temperature increases, reactor power decreases. All reactors have reactivity feedback mechanisms. The pebble-bed reactor is designed so that this effect is relatively strong, inherent to the design, and does not depend on moving parts. This negative feedback creates passive control of the reaction process.

Thus PBRs passively reduce to a safe power-level in an accident scenario. This is the design's main passive safety feature

The west is irrationally afraid, but China understands nuclear is inherently safer than fossil fuels after having lost thousands to pollution.

KDE connect is a life saver.

Cancelled pushbullet for it, it's incredible.

Those are old designs, new ones basically stop once the water is removed.

Hence the 'negative void coefficient', modern designs lose reactivity as the water is removed.

Look at pebble bed and other designs.
