I remember being a younger pup and building fleets of machines (including overclocking, etc) for the sole purpose of running S@H, and all of the amazing software the spun up around it... SetiSpy, SetiDriver, SetiQ. I often wonder how machines of today would compare in work production to my old Duron 800, but alas.
> Duron Now there's a name I haven't heard in a while. Duron, the poorerer man's Celeron.
Celeron 950MHz, 512MB RAM, 20GB HDD, 12x CD-ROM (not DVD :), floppy, add-on IDE Ethernet card. Win XP actually.
We have an unused Win8 desktop that we'll be refurbishing and gifting to her soon.

You make the case that political issues haven’t changed much isn’t he past 2400 years, but then go on to say you’d like to see us manage things here at home before expanding into space? Those seem to be in conflict to me. I do agree that human engineering has developed far faster than human politics, but I think we need to just accept that this trend will continue.
The conflict is exactly what I'm pointing out. It's pretty easy to imagine a minority of administrators on a space habitat decide they'll take some critical system hostage unless they get a bigger share of whatever they want because they think (perhaps legitimately) they've been the victim of some injustice... overplay their hand, critical system fails despite nobody actually intending it, millions of people in the h…
I ran it on the weekend once on the queue at Disney animation, maybe a hundred CPUs on SGI Origins. Went from zero to top ten-ish percentile in a half hour or so. Good times until I got a stern talking to by some systems guy.
Saying that as the lead Solaris SysAdmin for a large telco project a few decades ago, with one manager in particular who repeatedly kept on firing it up on the main (high end SunFire) billing cluster servers. Even when expressly told not to. That guy was a f*cking moron. :(

Radar. That's the RF that's easiest to detect from long distances, it's focused, and it's strong. The hard part is deciding if it's natural or artificial.
Top of my head, so I may be off, but: The Arecibo message was easily the easiest to detect by far. Its signal will become indistinguishable from background radiation at a distance of slightly over 625 light years. The converse: any life out there trying their best to communicate with us, beyond 600 ly... we wouldn't realize it even if we happened to catch (what's left of) the signal.
Doesn't that depend on how large the receiving antenna is, because the larger the antenna the smaller the source angle you can focus on and the less background radiation will be in that source angle ?

Yeah. You wouldn't believe the number of idiots that went around covertly attempting to run this (and similar) on the production Unix servers of their employer.

Sucks to know we’re alone and no one has reached out.

I'm sorry, what? Are you claiming we have created a livable atmosphere on another planet? Where? Which one? Are you talking about Earth? Humans did not create the Earth's atmosphere. We can barely "fix" the damage we do to it. "Fixing" is not creating.
He is saying that we are currently transformong the earth's atmosphere into a less hospitable one through a process of pollution / emitting greenhouse gases. In my view, given that we can do this, it is not unreasonble to assume that one day we will know enough to be able to tweak a planet's habitability in the opposite direction, or in other words, make an inhabitable planet habitable.
Aren't those the same thing? Shouldn't this be "make an uninhabitable planet habitable"?

Interesting. If I understand you correctly, you are saying that it makes more sense to look for large IR sources (without accompanying visible light), instead of looking for radio signals. Correct?
Correct. The signature of a large Dyson Swarm would be hard to mistake, particularly for anything natural, at least anything we've seen thus far.
Is the idea that the habitats would be much larger than planets or that there would be far more of them for a given total volume of matter ?

>>1. Habitats are mobile. If you don't like the neighbours you can up and move, something not possible with geography on Earth; That relies on the assumption that people within a single habitat wouldn't want to separate for whatever reason. Nation within a nation. It already happens on Earth(see: Catalonia, Taiwan, Hong-Kong, Silesia).
Getting my sci-fi hat on here but, it would in theory be easier for them to pool their money together and buy / build their own spaceship. Of course, this assumes that each ship is its own political entity; in practice, we'll probably see the equivalent of countries and states but in space, spanning territories and jurisdictions that span multiple habitats.
As in trade is very essential for growth. Both of goods and ideas.

> space habitats What about gravity? Is it possible/feasible to have long-term habitats without any meaningful gravity?
You spin them to create “gravity”, which is really just centrifugal force.
