Yeah, nobody has ever worn a mask to prevent spreading upper respiratory tract viruses <insert nuclear facepalm here>

At the risk of fuelling the HCQ fucktards - technically HCQ did demonstrate activity against Covid in a petri dish... At concentrations that could never be reached in any person before they died of overdosing.

Remember the XKCD: Lots of things kill cancer in a petri dish. Including a gun.

The maintenance/leak and the huge-damned-mess problems are why neither has seen any real adoption until the physics of heat transfer pointed a gun at everyones' heads.

Submersion in a low-viscosity coolant has one big advantage over waterblocks - it carries out total heat removal from all components instead of just hotspots, so you require NO other cooling. If you have waterblocks on the GPUs and CPUs, the chassis is still expelling heat from the power supplies, network cards and SSDs, so you still have to have an air chilling setup, it's just that the air heat load is actually tractable.

The big change for immersion cooling, I feel, is that it makes infinitely more sense for each chest of coolant to be wide and low than tall and narrow - in other words, it requires abandoning the traditional notion of the 19" wide 7-foot-tall rack. In the space of 3 racks, you would have 3 horizontal chests one above the other. You would disconnect machines by reaching into the coolant, slide the chest out on on extra-big-boy rails, then pull nodes out vertically. This lets everything else remain immersed and on, just as we expect everything else in a rack to remain on when one node has to be pulled.

Not only is it cheaper on these scales, the power dissipation of Blackwell and MI300 class GPUs is such that it's no longer possible to air cool them at full power. All current and future air-cooled SKUs for Hopper, Blackwell and post-MI210 accelerators in the datacenter are reduced-performance devices due to thermal limits.

My research group has two air-cooled Grace Hopper systems. This is a 72 core ARM processor, an H100 GPU and 480GB of memory all wedded on a single supermodule. The power dissipation is capped at 700W, down from the 1200W electrical limit. Each 2U unit has a single gargantuan heat pipe/vapor chamber whose heatsink is the whole 2U unit's face in cross section. There are two banks of four fans in a push-pull configuration. Each 3 inch fan at 100% duty cycle reaches around 25000 rpm, and each one draws nearly 3A off the 12V bus.

One can read right off that that's 36W x 8: Nearly 300W of heat generated by the fans moving enough air to take 700W from the heatsink. And that heat is now in a torrent of hot air, which must be forced through the datacenter's air chillers on its way back to the cold aisle, generating more waste heat.

For comparison, to absorb 1200W into water with a temperature rise of 10*C requires moving only 28ml per second of water through the heatsink. And that water can then be pumped at essentially zero energy cost - we're only talking less than a liter per second per rack - right up to the phase change AC on the roof, or into the liquid-to-liquid heat exchanger with river water on the cold side.

And 1.2KW per 2U is nothing. Current generation NVidia Blackwell class DGX systems make up to 1.5KW per 1U. Next gen Rubin systems will probably be 2.5-3KW per U, and super-Rubin will be even more than that.

Based on how things are going, we're in the universe in The Road Not Taken. Except worse.

To be fair, it was not until 2016 that the disgraceful Roberts court declared bribery and corruption defacto legal (McDonnell vs US), and not until quite recently in 2024 that the same cabal of lunatics declared bribery flat-out legal (Snyder v US) as long as you hand the money over after and call it a "tip" instead.

And to underscore just how guilty Roberts is of stabbing this country in the gut, neither of those are even in the top three of this disgraced court's worst decisions. No, those would be:
* Citizens United, in which Roberts was the deciding vote joining the other fascists on the court in allowing unlimited, unaccountable spending by the ultra rich to completely corrupt our elections
* Loper v Raimondo, in which the disgraceful supreme court voted to effectively make it impossible for any modern regulatory agency to do its job
* Trump v US, in which the disgraceful supreme court voted along party lines to declare the President a King above the law and themselves the King's Council to declare in what ways he is untouchable

For CU alone, John Roberts is the one single person more so than any other to condemn for the fall of the United States. Yes, even more than the bastard from Kentucky known as the Gravedigger of Democracy.

Even more simply put: These monsters are destroying everything that helps the American people, and makes America great, so that an infinitesimal number of oligarchs can get even richer by pocketing the money instead.

Brings to my mind reading about incredibly elaborate schemes for academic cheating.

The sort that when I hear of I think, "JFC man, if you'd spend half that effort on just learning the material you'd get an A without being a cheating piece of shit."

In the view of the kind of people who view "white skin" as a qualification, perhaps.

Here's the difference though - what Secretary Clinton did was what every SecState to have used email did up to and including that point because even in the late 2000s, the "officially approved" systems for handling and delivering government emails outside of local office buildings in DC were well known to be an unreliable dumpster fire (and before anyone starts wailing about "government incompetence," this is a situation of base-level connectivity in Middle Of Nowherestan and security against targeted enemy spying that is very, VERY different from the "any idiot can run postfix and mailman on linux with no security" situation the average doofus here is familiar with).

The SecState does a lot of time-critical things where "yeah I sent it isn't it there yet?" is not an acceptable outcome, so everyone had their own side-channel that would assure delivery if the "official" systems failed. Obama's administration was the first to actually try and in any way succeed at rectifying the mess. Despite being a "not exactly approved" situation, Clinton complied with all the usual records retention laws.

Then the GQP spent years and years losing their shit and going on unending fishing expeditions to tarnish Clinton's name. In the end we found out that a grand total of three emails out of forty thousand were classified, two of which were only classified after they'd been sent and one of which was a mildly time sensitive list of State Dept talking points for later public distribution (being, eh, talking points). And the 5th columnist corporate media lapped the endless turds up like they were mamma's mashed tater recipe.

On the other hand, what we have here at the present is a manifestly obvious deliberate violation of government records keeping laws with clear malice aforethought. They were conducting official government business using an app that flat asks you at setup time "how long do you want before each message here deletes itself?" You don't do that unless you are knowingly and deliberately violating records laws, and you don't do that if your actions are legal and above board (unless you're so unimaginably stupid that you enjoy committing crimes for no reason or gain).

As it always is when comparing wrongdoing by Democratic and GQP actors, it's a paper cut being equated with a limb hacked off by a chainsaw.

1968 was before the anti-nuclear hysteria. Oak Ridge had already declared the 10MWth MSRE such a success that they were ready to begin construction on a 250MWth prototype, which was to be outfitted as a small power plant demo, as the last step before full scale commercialization.

Then Richard Nixon, the Patient Zero of a staggering amount of all that currently ails and poisons our nation, joined forces with some Democratic senators from California. This epic nuclear engineering brain trust declared that sodium cooled reactors were the future and all other alternatives to the solid fueled steam bombs were to be dropped. ORNL was summarily ordered to shitcan the MSRE and halt all molten fuel research. When their leadership balked, they were told to throw it and all the research out or be fired. And lo, Richard Nixon had found yet another way to fuck us all; with one exception, every attempt at building a sodium cooled reactor has ended in total failure at best, with most of the early examples ending in partial core meltdowns.

Interestingly, the extreme corrosion seen in the MSRE power-shutdown only becomes an issue if the fuel is allowed to freeze. In the solid state, it is vulnerable to self-irradiation, and radiolysis liberates fluorine gas which eats everything. In the liquid state it's invincible to this process since, well, it's an ionic liquid.

The Democrats will try to hide how they are asking for more domestic fossil fuel production with ambiguous wording but they are clearly not making plans to put an end to domestic fossil fuel production, that would be economic and political suicide.

At this point, honestly, rather than actually taking explicit aim at one of the largest and most skilled sets of propagandists and liars in the world - the fossil fuel industry - it's far simpler and smarter to just push resources at the technologies that will obsolete them: Solar power, electric cars, and grid scale batteries.

The market is closing coal power down for us. With any luck, before the decade is out it will starting to close down gas power and well on its way to ramping down fossil fuel cars. Sure if we'd had President Gore to respond to 9/11 with a Green Manhattan Project instead of the farking Bushies we'd probably have been there fifteen years ago, but we're headed that way regardless.

"Your apps are stuck on your desktop, limiting productivity anytime you're away from your office."

Yes, oh God fucking forbid office notifications and work not follow us on the road home, into the dining room, onto the sofa, into bed and when we're out in nature.

And besides that... I'm not saying I haven't used connectbot on my phone if literally all I need to do is login into X and run one or two short commands, but have you ever tried doing actual real work with a phone or tablet instead of a legitimate desktop computer? In about sixty seconds you'll be wanting to suck start a shotgun. It's excruciating.

Credit cards, and the explosion of American indebtedness in general, and even social welfare programs now, are replacing the expected income growth that 90% of Americans should have seen for the last 45 years which we haven't because it was all taken by the ultra rich. The integrated productivity-pay gap is somewhere in the area of 50 trillion dollars now, that should've been paid to the workers who created the wealth but was instead thrown on Scrooge McDuck hoards of money that nobody could ever spend in their entire life if they tried to make them even bigger.

At that point, the answer is "the morons on what used to be the King's Council who thought they'd seized power for themselves discover that they had not, in fact, seized it for themselves." Or at least the survivors realize it before they unanimously proclaim the assassination of their colleagues an Official Act.

And remember - this was explicitly pointed out to the treasonous clowns in the majority and they still declared the President to be King, because conservatives in America have straight up turned against democracy.
