A stroke is caused by one of two things:

1. A blood clot blocking an artery feeding part of your brain

2. A blood vessel rupturing (aneurysm rupture) that causes pressure to build inside or against your brain, squeezing blood vessels shut like a pressure bandage.

Both of them cause a lack of oxygenated blood to the brain, and treating one type makes the other worse.

As an aside: the city I used to live in had an ambulance with a CAT scanner in it that would be dispatched to suspected strokes. They could diagnose whether it was 1 or 2 and treat it right away.

As to why arterial widening causes lacunar strokes, the article didn’t make it clear how or what small vessel disease is.

Gas exchange also doesn’t happen in your arteries or veins, but in your capillaries. Your capillaries are small enough to just barely fit a single red blood cell (the RBC often need to bend to fit through) and that close contact of RBC and capillary wall allows fast and near complete gas exchange. The tightness of a capillary is a feature, not a bug. So it could be that you don’t have consistent contact with the same RBC for long, and mostly are in contact with blood plasma?

Kinda? it depends. Basically all modern CPUs have compression hardware acceleration or idle cores, though so sometimes disk compression can have little to no impact on your OS’ speed but increase the bandwidth of your drive by a lot. Hard drives and SSDs are half simplex, so reducing nuisance reads by 10% can make your drive appear faster at both reads and writes.

As an aside, this is why I like ZFS so much. Part of what makes ZFS great is the ARC cache with smart eviction. Most Frequently/Recently Used (MFU/MRU) allows for repeated reads from the same info to come from RAM and not a slow pool. It opens up all of that available bandwidth and IOPs for writes if you need too, or for aggressive prefetching.

I think what’s funniest to me is he was very close to recreating a real windows feature. You actually can “compress files to save space” under options, and apply it to all child files and folders. This is not the way to do it though lmao

The other thing businesses do that should be illegal is target “high cost” employees.

Their healthcare insurance provider will provide them a monthly report and if you suddenly start $1 million worth of chemo it shows up in next month’s bill. The insurance provider doesn’t tell them who it is by law, but they DO tell them it’s costing the company a ton and hiking their monthly premiums. in a company of 100 people it’s not hard to figure out who it is…

Addressing the fact that junk food brands are owned by tobacco conglomerates might be a good first step. They have addiction scientists working with food scientists to make food more addicting. They can even make it taste horrible but you’ll crave it…

Regulating those blood suckers would be a good first step.

A 4 day workweek still sounds sweet though but obesity is a symptom, working 5 days is not the disease here…

Grandpa’s strongest potion:

10 lbs of sugar

As many crab apples as you can get from your grandpas crab apple tree

Juice them all

Mix juice with sugar in sanitized fermentation bucket (use starsan) and add enough boiling water to get up to 10% ABV on your gauge.

Rehydrate yeast in a lukewarm dilute sugar solution so you don’t shock it.

Add to mash and seal with airlock

Ferment until there’s no change in specific gravity between days

Rack your wash off of the Lee’s into a different jug and start distilling it with a water distillation still.

Once you have a first pass done, distill it again and toss the foreshot this time.

Stop distilling when the alcohol content drops below about 48% or when it tastes horrible.

Typically you end up with 68-80% ABV potion. Grandpa’s strongest potion also gives grandpa strongest hangover, so watch out.

Yep same. Got a 3 day ban for jokingly saying they should have tested a mk-48 torpedo on the hantavirus cruise instead of letting them scatter to the wind like dandelion seeds.

Not meaningfully, no. In the middle of a dry desert far from other bodies of water you could theoretically form cumulus clouds downwind of your site (I have heard of this happening), but it would be teeny tiny.

The amount of water evaporation is just orders of magnitude too small. The earth gets about 1kW of energy per square meter, so a 9GW data center is approximately the same amount of waste heat as 9 million square meters, which is 900 hectares.

There are also a few Inuit groups who made knives for centuries from a metallic meteorite that landed in the arctic circle.
