Well yeah, except their primary use case (literally, it's the first use case listed) is BIG DATA. It's fair to say that if you're routinely pushing and parsing terabytes of structured data, you probably can and should take a day or two to get the database optimized, no?
No. You're simply stuck in a mindset of high-value databases. Try low-value data, on a large scale, instead... Turn up your syslog logging to the maximum amount of debug, then expand that out to hundreds and hundreds of heavily loaded servers, then log it all to a central system, desperately trying to write that to a database for eventual aggregation and reporting... Consider something like an IDS or other monitoring on high-speed data networks, trying to keep track of data usage, in detail, on those gigabit speed lines all-around the clock.

Or just consider the cost of an extra server (with SSDs) versus the cost of hours of a DBA's time... For non-critical data in general, you're going to expand the cluster, rather than spend time and effort to tune things.

Who wants to run emulated Android on a battery powered handheld?
It isn't emulated, actually. Blackberry has an ARM CPU just like Android, so native apps can be run on the processor without any emulation. BB just has to provide compatible ABI hooks to the OS. This is a reduced version of what WINE does for Windows applications on Linux, but Android being open source means there's no need for reverse engineering, and having far less legacy means it's much easier to develop full compatibility quickly.

"In Wine, the Windows application's compiled x86 code runs at full native speed on the computer's x86 processor, just as it does when running under Windows."

And with the non-native Android applications, it's even easier. They're basically Java applets, interpreted by the Dalvik VM when run on Android. It's not big deal for other OSes to develop their own almost-JRE compatible with Dalvik, and run Android apps as well as Android.

I would only try a chimney mount to a heavy object, not a stove pipe vent, if that's what you mean. Even if you don't have a catastrophic failure, the added stress and movement is likely to shorten the life of your roof and cause leaks. If lacking large rooftop candidates, I most often prefer one bracket as high on the eves as possible, and a mast going down into the ground. Two brackets on the wall is even more-secure. Most other methods won't support a large antenna jutting up 10ft above the top of your roof.

A J-pipe dish mount works fine up to just a couple feet,... A tripod will let you go a bit higher, but still not nearly 10ft without supporting guy wires.

If you're concerned about making holes, there are "non-penetrating roof mounts" available, which set on top of your roof and just get anchored with bricks. You could compliment it with guy-wires anchored down at ground level, for taller masts... All without any holes in the building...

That's an incredibly low figure. I'd guess you eat out all the time, don't wash your own car, have no plants, don't do laundry, take very short showers days apart, and more. Or otherwise are away from home a great deal of the time. While that behavior may reduce your home water bill, you're still using lots of water, and in a way that's far more expensive than just using water at home.

With the standard 2.5 GPM shower head, 750 gallons is just 5 hours of running the shower per month, total. Some people take 5-minute showers, or skip quite a few days in-between, but most don't, and the average would also go through the roof in a household of several people, so that's not really a practical level of water usage to expect of people, except in cases of extreme rationing.

And showers aren't the biggest water users... Toilets consume more water, so you need to cut your showering time down to 1/3rd of that to fit the numbers, still. Throw in some dish washing, outdoor plant watering, and you get up to those big "average" numbers quickly.

I used to be a huge shortwave radio buff but now despite big investments in antennas, there's not much out there on the shortwaves. How is the trend going the other way in OTA television?
Shortwave, and radio more generally, is a format in decline (I'm very sorry to say), thanks largely to TV, so they're struggling for content. An interesting development is some news radio stations (CBS) playing the audio portion of TV newscasts... In addition, the growth of podcasting would seem to offer lots of fresh and cheap content ripe for syndication, but I haven't seen that happening. I consider the best radio content out there, but they don't have many AM/FM radio stations airing their content, and certainly no shortwave stations:

But I digress... video isn't going anywhere, and most original content comes from the big 4 broadcasters. And content on cable networks eventually gets syndicated on OTA channels, anyhow. In fact the switch to highdef has been driving demand for more content, combined with technology like digital cameras and CGI making it far cheaper to produce, there's ever-more and more of it coming out, not less. Industry reporters are calling today the "golden age of TV," with more big celebrities moving to the small-screen, more epic mini-series style shows coming after the success of The Sopranos, as well as technology (eg. DVRs, DVDs and Streaming allowing "binge watching") pulling-in larger and dedicated audiences. Sure, there's a flood of "reality TV," "CSI" spin-offs, and horrible sitcoms, but consider the astronomical success of: Breaking Bad, Game of Thrones, Downton Abbey, House of Cards, Walking Dead, Homeland, The Blacklist, Scandal, Agents of SHIELD, etc. etc. There's a huge amount of big-budget content on the small screen right now. And even where it's on cable networks, much gets syndicated to OTA a few seasons later.

It's just a question of distribution, and OTA is by-far the most inexpensive for the viewer. Cable had an advantage with the poor picture quality of analog broadcasts, and its ability to carry more channels, but HDTV reversed things, and digital OTA provides you the best picture available. The ability for broadcasters to multiplex multiple sub-channels means OTA offers much more content than before, further reducing the need/demand for cable. DVRs (and cheap DVDs) additionally eliminated the need for all those cable channels that mostly just syndicated broadcast TV shows, all for far less than the $70/month cost of cable... $800/year could be an awful lot of DVD rentals or purchases.

In addition, Netflix/Hulu/YouTube/etc., are making their presence known. People wanted cheaper and "ala cart" cable for a long time. Now they can get their favorite shows on-demand for ~$8/month over the internet, and that mode of distribution compliments OTA antenna TV viewing quite nicely. Streaming fills-in the occasional viewing of what people might be missing from OTA, but being weighing heavy on their internet pipes, being late/slow to get the latest content, missing local news and sports entirely, and more, so OTA antennas are able to perfectly fill-in the gaps in streaming, without the astronomical cost of cable.

For the post-apocalyptic future, you should stock-up on low-power computer and ham radio equipment, in a bunker and sufficiently EMP shielded. Shortwave radio would definitely be the fastest and cheapest way to bootstrap regional, national, and international communications systems again.

In the longer term, as long as people are around who remember which technologies worked out and which ones were dead-ends, and which feats were possible and which were never realized, the world would be rebuilt from the dirt, to largely-modern standards, pretty quickly. First farming the most successful crops, then engines and electricity, then information exchange. I

f you're going to lay a wire, you wouldn't resort to dial-up, at least not for long, but would jump up to something faster, like DSL or right to fiber optics.

The Middle East only has oil, which isn't used for electric generation almost anywhere, so solar panels aren't a direct replacement. Rising oil prices would spur adoption of PEVs, which might slightly increase electric prices, indirectly, but not too badly. A study of PEV owners shows they choose the option of peak/off-peak metering from the electric company, and then charge their EVs starting right at midnight, when rates are lowest. The higher electrical demand makes PV more attractive at homes with PEVs, too, but it's still a rather indirect relationship.

Germany certainly has a lot of solar capacity installed, but I don't think ANYBODY wants to copy that model... They got it done by driving electricity prices through the roof, several times higher than the highest electric prices in the US, to pay for it.

I would be very careful about that line of thinking... The current, ever-expanding definition of the term "sex offender" should be all the cautionary tale you would need.

Remember, if a woman regrets having sex with you, even a week later, the feminazis want you punished like any other rapist. THAT'S NOT AN EXAGGERATION. That has been instituted on several college campuses recently, and that's how we get so many mainstream news stories claiming women have a 1 in 4 chance of being raped, when the actual number is around 8%.

Right now, a teenager having sex with his slightly under-aged girlfriend can result in serving jail-time, and being a registered sex offender for the rest of his life, nearly unemployable and almost certainly homeless (since almost everywhere is too close to a school) for the rest of his life, under current laws.

Even an under-aged girl sending nude photos to her under-aged boyfriend, and him responding in kind, results in the boy getting prosecuted for producing child porn (of himself):

With current laws so completely ridiculous one-sided and extremely heavy-handed, I have no faith at all that newer technology would be used properly. Instead, you could end up with the entire male population forced to get such implants.

There are actually just 4 major terrestrial digital TV broadcast standards in the world:

The various details of each (eg. codecs) are handled in software easily enough. Heck, if you just have a basic tuner that can grab a ~6MHz chunk of the spectrum in the target frequencies, software defined radio could do all the RF decoding for you. Only problem for SDR is that old analog TV tuner cards separated video from audio before output, so chunks of the digital signal are missing, and you have to jump up to ridiculously expensive specialized non-consumer hardware. One company demanding such a thing could push the economies of scale, and get it very cheap.

I don't see any reason to include satellite/cable/etc tuners. OTA is the only one that'll be convenient for tablet use. If you want cable/satellite on your tablet once you've wall-mounted it, you can use whatever converter box is convenient, via HDMI input.

That's not Sci-Fi, it has been standard operating procedure for the past half-century. Convicted rapists in many situations (depending on jurisdiction) have been required to take pills or injections that reduce sexual urges, as a condition of their parole for many years. It has been happening in the US since 1966, and is law in several states. In Europe, Alan Turing chose that punishment for his homosexuality, rather than jail time, back in 1952:

Why don't tablet makers include HDTV tuners, and HDMI inputs?

For minimal extra cost, your tablet would be much more flexible, and have a vastly longer useful life-span.

Just imagine that your beloved tablet could double as a computer monitor. That would be a killer feature for any techies. Adding that capability to a laptop costs over $300, and people are happy to pay it:

And once your tablet gets to be a bit out-of-date, instead of throwing it away, you can just mount it on a wall connected to your antenna as a (free) 10" HDTV. And a very "smart" TV it is, at that, able to integrate Netflix/Hulu/etc. streaming without needing an extra $50 Roku/Chromecast box attached to it.

Or if you don't have a need for a small TV, it can go on your desk, doing duty as an LCD computer monitor. Heck, you could use it as a computer monitor right away, and just have the option to use your monitor as a tablet for quick tasks without starting-up your noisy and power-hungry main computer.

And that's not even mentioning the benefit tablet users would get from having a handy HDTV tuner with them all the time. In most cities, an internal antenna is good enough to pick-up several TV channels, so you'd have lots of free content available whenever you wanted to watch, without the need for high-speed internet access for streaming the video. Of course there's always the option of connecting a larger external antenna, even if just a long piece of wire yu scrounged up, in reception-poor areas.
