The short version is that life needs something that's at least a little unstable in order to extract chemical energy from things.

The post is correct when viewed in a particular light, on a technicality, if you squint. By that same technicality iron rusting is also burning very slowly. They're ignoring the rapidity which is implied by "burning". But yes, oxygen is unstable, oxygen helps burn things, and oxygen is toxic if you get too much at once. Though you'd need to be breathing pure oxygen pressurized to about 1.4 atmospheres, or regular air pressurized to about 7 atmospheres, for that last one to happen. It's a legitimate concern for deep SCUBA divers.

But why does life need instability? Chemical instability is, in basic terms, just stored chemical energy, and that energy wants to be released. The more reactive something is the easier it is to get energy from reactions involving it. There's a balancing act here where more reactive means easier energy, but also more dangerous. Oxygen is in a kind of sweet spot where it's stable enough that it's not generally going to explode or catch fire on its own, but can be coaxed into doing those things in controlled ways with other chemicals to extract energy when needed.

Alternatively you do like the Parker Solar Probe and do 7 Venus flybys, bleeding off a little speed each time with an inverse gravity assist.

Now look into °De. It's upside down!

It's an extremely bizarre suggestion given your request. I do want to defend the game (though not the suggestion) a little though.

It initially presents as you say, but offers you opportunities to fight back in your capacity as border control. Letting in the right people can help the resistance and incite a coup, or enable you and your families escape from the country. It isn't just Be A Good Tankie Simulator 2013, though you can play it that way too.

You linked then to the already linked video they were complaining about.

They had a reveal trailer as part of the PlayStation State of Play back in May, and basically the entire internet collectively lost all interest the moment it revealed that it was a 5v5 hero shooter.

Yes, if you consider just a human-mass equivalent portion of the Sun then it's not doing much, but that's not really a useful comparison. We're talking about total net entropy here, not entropy per unit mass.

But yes, if it makes you feel any better, I'll concede that if you had octillions of people our total metabolic energy output would, in fact, be significantly higher than that of the Sun.

On the overall scale of the universe? No, not even remotely close. On the local scale of the Earth, generally yes.

For those of you who've never experienced the joy of PowerBuilder, this could often happen in their IDE due to debug mode actually altering the state of some variables.

More specifically, if you watched a variable or property then it would be initialised to a default value by the debugger if it didn't already exist, so any errors that were happening due to null values/references would just magically stop.

Another fun one that made debugging difficult, "local" scoping is shared between multiple instances of the same event. So if you had, say, a mouse move event that fired ten times as the cursor transited a row and in that event you set something like integer li_current_x = xpos the most recent assignment would quash the value of li_current_x in every instance of that event that was currently executing.

I'd argue that they still exist, unless we're just ignoring prison labour.

I was surprised to see that they dug a verse from the Book of Enoch. It's not even considered to be canon within Christianity or Judaism.

Women are you using a Xerox multifunction device location to this email and any attachments is intended only for the same time and consideration and I will be in the first time in the first time in the first time in the first time...

It loops on that forever.
