That, or developping time-travel / multiverse-shift.
I don't trust anything Musk says. His lies and temperement is actually the main reason I have anything against Tesla.
All of the above.
I assume Tahr had to go retest everything with OpenSSL updated to avoid the Heartbleed bug?
JEOS (Just Enough Operating System) used to be a sub-version of Ubuntu, with a minimal server edition; anything else you wanted was an apt-get install away. But there hasn't been a real JEOS version since about 8.04 or so, and with virtual machines these days I have a need for a lot of small-disk-footprint VMs. Is there something that's relatively similar, with basic networking and maybe a LAMP stack?
It would be nice to have a basic X windows environment, but I don't need big piles of Gnome or KDE, and I definitely don't need OpenOffice or lots of the other fun tools. Thanks!
But how does Evolution prune the repication mechanism itself? If an early replicator was very sloppy and mutation prone, then any possible advantages occuring by random mutation would have little chance to be tested before other random mutations overwrote them or other mutations killed off the organisms carrying that mutation. Working backwards, let's start with modern DNA, in cases where there are many additional mechanisms to cut the mutation rate so the non-random part of Evolution has more time to work. Putting DNA inside a walled cell, and making that cell nucleated, both reduce the exposure of the DNA to chemicals that can mutate copies. Multicellularity further shields the DNA from some more mutagens, and lets Evolution prune cells with bad copies by apoptosis, which can't be used by single celled organisms. Right there, we have a trend in Evolution - Nature seems to be trying to reduce error rates to target, as you put it, the Goldilocks range. "Advanced" organisms, such as us, or mosquitos or oak trees, have many features that make the selection rate occur at an optimum, where Nature gets enough time for selection processes to occur. In fact, sexual selection is probably just another form of targeting that Goldilocks range, and I'm sure a professional biologist can think of may more examples than the four I've mentioned. Some more minor steps in this pattern might include the evolution of Alcohol Dehydrogenase enzymes and others, but that's getting beyond my depth.
But if we extrapolate a historical trend from that, the mutation rate must have been higher for 'primative' DNA based life, but the selection pressure must have been lower. Mutation must have been still higher if RNA was once the core molecule of heredity, which seems pretty solidly established. And if there's several more primative replicators, selection pressure must have moved glacially compared to the modern era. So how did selection have time even in 3 billion years to evolve DNA itself? If the earliest replicators were something like crystaline clays that were subject to a very modest amount of selection by erosion, as some biologists have speculated, how do we get the time for these to evolve through many stages to RNA and then DNA and eventually all the extra trimmings of today? Given that we've been in a DNA based biosphere for close to 1.5 billion years, that's about half the time since Earth cooled enough to support organic compounds,, and we're trying to cram probably at least 5 or 6 earlier replicators into less than half the time, knowing that each one was subject to less selection pressure than it's successor probably by orders of magnetude.
We can't "save a step and conclude that the universe always existed" because we think the universe had a beginning, the Big Bang. We could have saved that step if we thought the universe was Steady State. Dr. Sagan is asking this as a rhetorical question, yet he himself gave the answer not 20 pages earlier in the same book when he addressed the Steady State/Big Bang controversy in historical physics. That's showing a completely non-scientific bias and committing a logical error, and I really hoped for better from the good doctor. Fortunately, if there Is a real God, I suspect "he"s not going to be that hung up on whether his creations beleived without evidence or not.

It's perfect! Unsinkable? Unthinkable!
No Homer will ever be allowed, and all the regulators will be objective and unbowed!
A floating platform several miles offshore, moored in about 100 meters of water, would be unaffected by the motions of a tsunami; earthquakes would have no direct effect at all. Meanwhile, the biggest issue that faces most nuclear plants under emergency conditions — overheating and potential meltdown, as happened at Fukushima, Chernobyl, and Three Mile Island — would be virtually impossible at sea."

The US president is a Spokesmodel.
The last vestiges of Presidential authority as actual executive were blown out of JFK's skull, 50 years ago. The real rulers have allowed the cosmetic changes of politics, without substantial challenge to policy or imperative.
That's why you can argue successfully to let fags into the imperial legions, but not if such legions should be withdrawn from the globe and disbanded.
False conservatism, false progressive/liberalism. Everybody in the US takes a hot shower and drives to the mall, on the burnt bodies and broken future of a million dead babies - hidden in Congo and Yemen and Indonesia and...
