Rather strong language there, AC stranger. Too bad you're wrong. I said the pc is on 24/7 ANYWAY. Instead of 4 of them on all the time. Also, I have attached a duct which vents its heat right out the window, lol. Physical access to the servers prevents others from seizing control and taking them over to operate as their own. As in the case of an asshole HOA that wants to boot me off my forum and neighborhood site, and run them their way. Which they did once last year. Someone very resourceful might mitm the external traffic, but I know I can always regain direct admin access even if I get hacked. You have no idea how good the security is here. Suffice to say it is excellent.
I have my own cloud. I save on electricity by packing multiple servers into one box which is on 24/7 anyway. Having the servers physically located beside me relieves me of further concern that my hardware, website or forum might be seized or MitM'd. Also, the HOA can't sweet-talk some meddling corporation into kindly muzzling "that scofflaw.":)
Yeah, one of the perks of running servers on a residential line is seeing firsthand all of the exploits. I'm fond of decrypting those mime-encrypted javascripts embedded in urls and finding the patebin page or hostname which it tries to fetch more scripts from; getting that shiat reported. If I were evil, i could build quite a library of exploits to use on others. They just send me these things haha!
Here's my observations, as an experienced ISP CST and admin.
In the scenario of muni backbone + private provider, the ISP you choose will primarily be your BILLING SERVICE. Also, they take responsibility for customer service and technical support, they're an intermediary between you and the municipality who won't talk with you directly. A concierge. And they're likely to provide "value added" services which the other ISPs don't, and which you can't get for free. I can't think of a single thing this last could entail, but the customers don't always know that and the ISP will pre-install it on your PC "for your convenience" using their un-necessary install disc.
The dominant ISP will either be the cheapest choice, or the one which does the best bullshitting about the 'excellence' of their service.
Damn, but you're mad about this 100% free service!
The install script doesn't stay resident or seize resources from your server. It performs the automated confirmation that you're the owner of the website you're applying for. You actually don't have to use it, but you'd have a lot of work on your hands otherwise. I use Let's Encrypt certs and couldn't be happier. The only problems I've had with it are where I link to content on my servers, and the forum/host that I wanted it to appear on is unable to fetch it. In the long run, that's an added bonus since I've had problems with hotlink abuse anyway.
Dude. Enjoy your cold, dry rock and osteoporosis. You'll be able to move in about 10,000 years from now at a cost of 2-3 quadrillion dollars. We'll think fondly of you down there, from our millions of comfortable orbital colonies.
Clarification on "planets are too big and unhealthy for our biology": meaning planet's gravity wells are too dangerous and expensive to get on and off of, and yet *too light* (or too heavy) to provide proper gravity for our biology.
While you're building 'a few superconducing rings around' Mars, and trying to collect enough energy to continuously power it, my tribe will be building hundreds of spacious orbital cities. Enjoy your cold, dry rock and perpetual osteoporosis.
Well, we cannot summon up gigatons of nitrogen-oxygen atmosphere for Mars, magic or not. And if we somehow organized and funded the many-centuries-long terraforming project to do that, then we still have a hunk of rock that provides too little gravity for our health, and it'll still be cold a.f. with a tiny, dim sun in the sky. Mars is unsuitable for multiple reasons. People like Elon Musk romanticize about "colonizing" Mars simply to engage people's imagination. With so much free-floating material in space, Mars is close to the last place we want to live or try and exploit for resources. Let's spend those centuries building spacious, comfortable orbital communities instead.
"So my preferred solution to the Fermi Paradox is that, a very short time (like a century or so) after a new civilization becomes detectable by radio signals, it doesn't necessarily die out, but does becomes UNdetectable again, as its radio technology improves beyond recognition at a distance."
I agree, and this same argument was made a couple of decades ago as humans transitioned to cabled transmissions from transmission of tv and radio over the air. The overall level of radio energy broadcast into space was thought to be dropping. Wifi and cellular phones seem to have flipped that trend again, at least for now. However, the way we use radio now possibly makes our transmissions less detectable over great distances. They'd just be seen as peaks in several bandwidths. Alien skeptics can probably find plenty of reasons to explain these as natural phenomena, lol.
Of course no one wants to live anywhere that isn't earth-like. There's no other place in the solar system suitable, so we have to build our homes. Please re-read my initial post. As I explained, the moons would be material to build orbital colonies. Crunch up the rock, sinter it into a cylinder shell.
We do not need Mars! We only need its moons - as an afterthought, at that. Mars is too light to provide proper gravity, too cold, and atmosphere too thin to protect from radiation and meteors. We cannot and would not want to live there. Ya gotta get your head out of the 1950's scifi assumption of living on alien planets. We have Earth, and we'll have manufactured orbital habitats.
It will take millions of years to actually dismantle the moon, so Earth and its tidepool crabs are safe in the long run. We need to start with the moon since it's 12 orders of magnitude closer to home than anywhere else. Good practice for a few centuries. Local transportation can be done efficiently through orbital skyhooks. Then, Mercury is next because power is so accessible there. Other moons and asteroids come later since energy would be harder to collect to run operations.
There's not going to be any terraforming of Mars or Venus or living in tunnels or domes because that's the way goblins live, not humans.
Planets will not be mined or lived on permanently, the gravity wells are too deep. Moons will be mined by scooping up surface material and refining them for valuables on-site, and flinging those into orbit via mass driver. The asteroids will be mined by pulling huge bags over them and breaking them all up inside. Other teams will revisit these bags of tailings to use the material for colony building. Mining and colony building will be virtually completely automated.
They can be built around any reasonably stable star (especially very long-lived red dwarfs) which has some rubble to rebuild into spacious habitations. No need to seek a proper star or habitable/terraformable planet. No need to genetically warp ourselves or live in underground tunnels like morlocks. The Colonies provide the perfect living conditions for the builder species.
Communication networks are likely via line-of-sight laser or some means we can't comprehend, so there's no transmissions for us to pick up. Hundreds of millions in number around each star, they're still too wispy to show up at distance as much more than asteroid fields or protoplanet belts. Being self-sufficient, it's no big deal when one colony decides to make the long, slow journey to the next uninhabited star. There, they get busy populating the colonies pre-built by robots sent ahead. The universe is old enough that there has been time for every star in the galaxy to be homesteaded by now.
We can get started by dismantling our own moon for material, moving on to Mercury and Mars's moons (planets are too big and unhealthy for our biology) until all of the available floating rock has been utilized. The colonies aren't made of girders and sheet steel. They're built by sintering crushed rock in the beam of focused sunlight, building up the superstructure like a gargantuan 3D printer. To simplify energy collection, the second or third generation of colonies are probably towed close to the sun, to minimize the size of PV panels needed.
To clarify, I'm saying that fast.com keeps saying that my Internet speed is *exactly* 100Mbps. And I have a 1,000Mbps connection anyway. Fast.com won't report my connection as any higher than 100Mbps but occasionally reports that it's slower. I checked my settings and performed some tests; my NIC is at gigabit speed. My switch is showing a gigabit connection, I can xfer files between PCs on my lan well above 700Mbps and most other (gigabit capable) Internet speed tests show I have 300-700Mbps.
Eh, no. I have Google Fiber. I've performed about 10 tests in a row now. First, it measured my speed in the mid 20 and mid 50 Mbps a few times, and now it's showing my speed as a nearly rock-solid 100Mbps for most subsequent tests. There should be more variation, and It should be showing 4-10x faster speeds (based on speedtest.net and google's speed tester). This thing isn't accurate.
Does it involve an intricate mesh of nested brackets, braces and parenthesis? Mandatory tabbing and trailing semicolons? Conditions expressed by single punctuation makrs, which are reversed if the character appears twice? Variables, commands and functions chained together with periods? Does it support oodles of ways to disguise and execute destructive code? Am I going to have to repeatedly insist to my boss that just because I can replace a blown PSU that I'm not his man to code the website?
This is the point I came here to make! Obviously, a Dyson does what any fan does when siht hits it. It's meant to dry WASHED hands off, so JoAM's "study" is full of it.
A silo shaped datacenter does make more sense for natural ventilation, but is much more expensive to build. They build them like warehouses instead, because it's the best way to save on upfront costs.
A silo full of detachable pods, and elevators capable of moving them is impractical. That's a lot of weight and infrastructure for so little utility. These servers don't need to be replaced often. Plus, you'd have to take a whole pod offline to move it. It makes far more sense to have a cherry-picker for techs to ride up in.
I would design a silo-shaped datacenter in two layers. Cold air would be forced/drawn up inside of a central duct. Servers would be arranged in a ring around the inner tube, with motherboards in vertical orientation. Fine metal screen-mesh, not sheetmetal, will keep EM noise down. Cool air would be drawn from the central tube to flow across the server's components. Warmed air would expand outward to the airgap between servers and outer wall, and continue to rise on their own from there, through transoms leading outside. It is important to maintain stable temperatures, which would be impossible in such a large vertical space. The tower would therefore be horizontally partitioned and have multiple air inlets and outlets at different elevations. Airflow would be passively managed using motorized baffles, and have active cooling fans when needed.

I like the idea of 2.5 years (time served) and giving him $104M reward to Snowden for his heroics.

Well, I guess we have to wait and see if Snowden is convicted first, thus vindicating those thousands of accused criminals.
