They're cheap because they're older hardware and they sell out to email spammers. Works great as long as you don't need a good IP reputation for email delivery.

Cheapish, okay support, reliable in my experience:
Yes, Ubuntu has AppArmor and Fedora (RHEL, et. al.) have SELinux.
The problem is that both systems are quite difficult to use properly. The out-of-the-box configuration is good for a base increase in overall system security against common threats.
However, if you want the real isolation benefits that these MAC systems are capable of providing, you'll need a full-time security team with years of training to manage your personal desktop.
Well, the Black Death killed ~15% of the world's population in the 14th century[1]. 15% today would be about 1.17 billion people. It's horrific but not implausible.
Yes but that was during a time before we had even entered Enlightenment. I don't see how it says anything about consequences of a 1.5 degree average warming.
We've literally spent trillions of dollars already to combat and mitigate change. We spend $500B annually just on solar panels. Add in the amounts we've spend on wind turbines, EV's, methane capture, etc, and we're spending over $1T per year combatting climate change.
It's not enough, but this meme that we're not trying is silly.
Graph of CO2 level in the atmosphere doesn't show even a tiny sign of those efforts. Sure, they are all good and commendable, but here we get zero points for the effort. If we reduce emissions a lot, really reduce them across he globe, this will simply mean that we will slow heating speed, not the target temperature. Like turning oven regulator from 3 to 2.5 - oven will still reach maximum temperature. CO2 level is the regulator.
For some reason no one wants the obvious solution, a global price/tax on carbon. So what you get is some countries spend billions on solar while others crank up almost untaxed fossil fuel use.
Even in one country like the UK were I live we have stupid expensive electricity combined with basically no tax on heating gas/oil.
I'm honestly puzzled why it's like that. Why do others not think a carbon price is a good idea and instead say let ban plastic straws while having zero tax on carbon for heating - that'll fix it? I don't get it.
We would never agree on a global tax system in the first place. We could tax wars for example, and those kill humans directly, unlike climate change. But we don't do it, because many humans benefit from wars. Same with carbon tax, too many countries benefit from not paying it and so they won't.
Second problem is that carbon tax won't help. It doesn't reduce emissions much (because realistically countries would rather pay than de-industrialize in short term), and it doesn't remove CO2 from the atmosphere at all. As I wrote above - a slow down of emissions won't really change the final outcome, it will only prolong the heating process.
That's the problem I was talking about. We humans can't measure emissions, we can only cleverly estimate them. Especially if the number we want is a global one, a sum of every tiny source plus every big source in every country, from democracies to a closed dictatorships. So when institutions show that badly estimated rate of gas inflow is decreasing, but the actual amount of gas is increasing, then the only logical answer is that inflow measurement is broken. Emissions estimates are broken, because total amount of gas in the atmosphere is only ever increasing and the rate of increase is accelerating.
Well, yes, they both show almost no impact from our green initiatives on the actual data. Emissions graph is increasing, and very slightly slowing rate of increase in the past few years. But the CO2 graph is a direct measurement of total CO2, so it is effectively a cumulative graph. And it is lowly curving up, accelerating, over past decades including last few years. Even if we magically flat line emissions graph, meaning no more increases of emissions, we will still see CO2 graph increasing and likely accelerating due to compounding of factors and existing CO2 levels already in the atmosphere.
There's a video game of this called QuickSpot. Back in 2008, this was one of my favorite games for the Nintendo DS. It trains the ability to spot little differences quickly. Sadly, outside of winning a barely known video game, it's not a super useful skill.

I don't know if this matches anything you achieve through meditation, but I've had some incredibly complex and vivid dreams that make me question everything about myself and my brain. I tend to agree that it just comes down to an astonishingly powerful organ flexing its power.
