This is partisan hackery of the worst kind!
Clearly we are in orbit of a Kerr black hole, whose axial rotation is causing the light to shift according to frame dragging!
Leave it to the blues to assume everyone is moving towards them!!!

I am less certain about Microsoft, though I think they need to have their ass handed to them for their high-handed treatment of push patches.
Either they need to implement staggered deployment by default, or they need to get out of the update deployment business altogether if they don’t want the liability, can’t have it both ways.
We know this didn’t happen, because CS.

Yeah, I didn’t do the carbonic acid, then there’s the increased bicarb buffering around the pleura, couple other facts.
www.ncbi.nlm.nih.gov/books/NBK539815/
Upon entrance into red blood cells, carbon dioxide is quickly converted to carbonic acid by the enzyme carbonic anhydrase. Carbonic acid immediately dissociates into bicarbonate and hydrogen ions. As previously stated, an increase in hydrogen ions stabilize the hemoglobin in the T-state and induces oxygen unloading which leads to shifting of the dissociation curve to the right.[6]
Thus the acidity causes o2 release. Temperature (lungs tend to be very cold in the body) is important too.
Oxygen unloading is favored at higher temperatures which will cause a rightward shift. On the other hand, lower temperatures will cause a leftward shift in the dissociation curve. A notable example of this is exercise, where the temperature of muscle increases secondary to its utilization, thus shifting the curve to the right and allowing oxygen to be more easily unloaded from hemoglobin and deliver to tissues in need.
It’s amazing how subtly it works to gently increase efficiency where we need it. Otherwise it’s just a very weak oxygen bond (which is hard enough given oxygen is extremely non-polar and all you have are the valence pairs.

Wow, I’m impressed, they’re using spin-coupling which is a pretty dicey effect.
Thus, we can conclude that the facile binding of O2 to hemo- and myoglobin arises primarily as an effect of the topology of the binding curves for the four relevant spin states. This topology, with nearly degenerat>e and parallel curves, is caused by the near degeneracy (within 10 kJ/mol) of the triplet and quintet states of deoxyheme. Therefore, the design by nature of iron porphines having close-lying spin states of a particular symmetry and energy is a means to tune binding of small ligands and overcome the activation barriers of these spin-forbidden reactions, despite the moderate SOC of first-row transition metals. The resulting barrier height makes up most of the rate enhancement due to the exponential dependence on the rate, whereas one or two orders of magnitude may come from the increase in the transmission coefficient.
That’s some fucking crazy ass engineering by nature, A weak, highly reversible bond with the molecule keyed to both pH and thermal triggers. That was a fun rabbit hole.
- Comment on Colours of Blood 4 weeks ago:
-
It’s sensitive to pH, so it absorbs oxygen more readily in the lungs, and releases it slightly more near tissues that need it, as they have co2 which slightly acidifies the blood in solution (h2co3).
-
It’s effective and well tuned for our biology, it doesn’t bond strongly, and is well suited for the air-blood interface, unlike others that often favor water-blood or water-the fluid worms use instead.

- Comment on Why are laptop adapters so much larger than phone adapters of same power rating? 5 weeks ago:
-
They don’t have to, I have Gan chargers that do a lot.
-
Less pressure on laptop manufactures to shrink as much.
-
Duty load: the big one.
You’re not just charging an hour at 20w and unplugging it, or tapering the charge, you could be using it at max rated output for days, that means much more stress, it needs to radiate more heat, and generally needs to be bigger.
As for fluctuating load, shouldn’t be as much of an issue, laptops often do their own power conditioning because the battery is fairly rough, and you’re going from 12-20v down to 5 and 3.3 then 1.6 and 1.3 to vcc for the chip, there’s plenty of filtering at each stage and they’re isolated by the smps controllers and input caps.
But pulling constant rated duty cycle basically doubles the size of power supplies normally, GaN technology helps a lot (which is why those little power bricks can do 100w+ now even though they got a lot more dense).

The funny thing is: All the really intelligent people in the soviet union, the ones who developed stuff like nuclear bombs and missiles and their decent ships?
They were Ukrainian, which is why they’re suddenly building hunter-killer drones in a cave out of a box of scraps.
Worked with Ukrainian engineers, I would not get on the wrong side of them for any money, Russia can throw as many of its children as it wants at their machine guns, this won’t end the way they think.

- Comment on Sending intranet Email on a token ring network still used the same process as creating a Memo 5 weeks ago:
The whole point was that cs/ma (check if anyone is talking while you’re talking) was a competing strategic to token ring (everyone can talk in their turn).
You could lose most of your bandwidth under contention with csma, it scaled poorly and routers/switches were crazy expensive because they needed to have memory to buffer packets at full flow.
Somebody made an integrated switch ASIC and the price plummeted and suddenly every network was switched.
