Yes but X99 and DDR4 blows any chance of doing Haswell-E on a budget. I need a new PC and is considering either 4790K or 5960X, the former is fine now while the latter is going all out on new tech which I hope will last longer. Eight cores crushes the mainstream chip in multithreading. Eight RAM slots in case I want to double up, of a type that will exist long and improve much. Plenty PCIe lanes. Slightly weak single threaded performance at stock but considerable overclocking potential. With 10% performance improvement per generation it'll take ages until I need an upgrade again. On the other hand, a 4790K might last me long too.

No. At least not one that makes sense for storing one or two copies of a consumer hard drive. And you're stuck with a huge investment in one generation of tapes, unlike HDDs where you can gradually buy bigger and better drives. I'd rather see hard drives get cheaper and tape not than nothing getting cheaper at all. What's the real practical downsides to HDDs for the average person anyway? They're standard and can be hooked up to any computer (real fun if your tape drive dies on you or is lost/stolen). They're random access. Without a tape robot it's not more convenient. Without a environmental controlled tape vault I wouldn't trust their longevity claims.

Personally I think the ideal consumer backup solution is three hard drives, one offline next to your computer and one online hooked up via high speed Internet. Anything that nukes your files can't get to your offline copy even if the online copy is hacked or accidentally sync'd, anything that destroys all local copies like theft or a fire can't get to your online copy. One drive goes bad and you should still have two good copies though RAID1 on your main computer would be nice, just to avoid the downtime.

And for what it's worth, most consumer data isn't really worth backing up as they're just a cache to the Internet. I just checked and my total personal stuff (photos, videos, documents, source code, whatever) is 370GB, while I got 10TB+ of other things. And a lot of that which goes under personal is actually "backed up" in that friends or family got copies too, so strictly speaking I could do with even less. I actually see they have 512GB thumb drives now (at insane prices), actually my whole backup could fit in that now.

Well, from the looks of it a coax cable can carry anywhere from 1000-1500 6MHz channels @ 42.88 Mbit/s so 42-63 Gbit/s, subtract TV channels (200 @ 10 Mbit? = 2 Gbit/s), divide by number of subscribers sharing the rest. It shouldn't take that much money to cut a loop in half though, just pick a midpoint and run two coax cables straight to the central office. Considering how rapidly things progress with competition I really doubt there's any technical difficulty in delivering more.

Like Windows, OS X, iOS, Android and.... who exactly has a network transparent protocol? The X protocol was designed when X was essentially drawing boxes and text to a frame buffer. Today the GPU is by far the second most powerful - and in some ways, the most powerful computing device in a computer. The absolutely biggest, fastest link is between your CPU and GPU with a 16x PCIe 3.0 link (15.75 GB/s) and companies are working hard to create heterogeneous computing where they even access the same memory pool so you don't even have the bus overhead. Putting a network in the middle is like replacing a mainline water pipe with a plastic straw.

The lie is that you can do network transparency without compromise. Just because the protocol is transparent it's still a straw and applications don't know they only get a sip and not a fire hose of bandwidth. Those who assume they will fail miserably and are practically unusable over a network since there's no way for the protocol to scale down the traffic. If you've got a fast network, do RDP/VNC. If you have a bit of bandwidth, do a web interface. If you have very little bandwdth, do text mode SSH. X forwarding? If I absolutely need to have an X app running (no command line, no web interface) and I'm bandwidth constraint, but it's the least bad solution to a bad situation in the first place.

You do realize that if they actually did that /. would be howling about 1984 and Idiocracy and how it's NSA propaganda to "trust the system" and stop thinking for themselves with pages full quoting Franklin about security and liberty. After all it had to be about humanity willingly handing over control, we already had the story were they assume control by force and that's a villain story (I, robot). Meanwhile regular people like to identify with their heroes, the villains may be monsters or aliens or robots but the heroes are 99.99% human(oid). Nobody cares that you can't identify with Sauron or Smaug or King Kong or the Borg, but for a hero AI that's going to be tough.

You have it in the Swedish series "Äkta människor" where humanoid robots = hubots are blurring the lines, but it's more of a rebellion/independence story where they're breaking out of servitude and they're certainly not humanity's heroes. As an AI story it's more along the lines of Her, with humans and robots getting emotionally involved in each other which is probably not the kind of movie you were looking for. The superior intelligence kind of robot wouldn't fit in there, if you can't care about the hero I suppose you could care about the victims of whatever conflict that is drawn up. But those poor, helpless humans who can't fix their own situation but need outside help? That's a bit dreary.

Besides, I think that's a bit too similar to actual problems in the world today, movies like to show empowerment. People sympathize with those who are powerless victims, but they don't want to identify with them. And if the AI is smart enough to control bad guys, wouldn't it also be smart enough to control the good guys? I think it would be very hard to avoid it ending up as a giant puppeteer who's now pulling all the strings. And that's again more of a creepy story where you're being manipulated without you even knowing it, like the Matrix before you take the blue pill. There is the War Games computer who learns that the only way to win is not to play but I'm really struggling to come up with another computer "hero" story.

I think you vastly underestimate the difference between knowing that "people" in the abstract, far away sense are tortured and killed compared to people you can put a name and face on. If you had to see a third world slum kid over webcam for 10 seconds each day, look him in the eyes and tell him you're not donating anything today I think most would crumble very, very rapidly even if we were relatively short on cash themselves. Yes, their goal is to spread fear and terror. The flip side of that is also to spread righteous anger and determination that such evil must be scourged from the world. If you could gather the IS warriors all in one place and aim a nuke at them, I'd push the button. And if you knew me, that's way out of character. Shit like this is what drives me to such extremes, if I didn't see it (not that I've actually watched this particular beheading) I wouldn't have felt so strongly about it.

Ever hear the proverb "birds of a feather flock together"? Whether you like it or not, getting an A on a test where everybody else got B and C is going to set you apart. Kids with self esteem issues will help with the divide "You got an A? You are such a nerd. The teacher's pet." and try to win their battles in the social arena, on the sports field or just turn to bullying you. Sure, you might get the better grades but he got to give you a wedgie. Good interpersonal skills might help bridge that divide but in the school yard network effects are huge. If a leader or clique first decides you're a nerd and uncool and don't want to hang out with you then everyone who wants to stay on good terms with them will join in.

Not that it was the only kind of grouping of course, the pretty and slim girls did the same to the fat and ugly girls. The stupidest of the class was also mocked and became the laughing stock of the whole class. Once we were a little older there was the rebels, who had failed at most everything else but made breaking the rules the measure of a man turning the biggest loser into the most badass. I suppose you can argue that some chose to be outsiders, but I know for a fact that many got shoved out into the cold. Then you turn to other outsiders for friendship and so you're a bunch of nerds hanging out, which reinforces the image everyone has of you as a nerd already. This is schoolyard politics 101.

That's not a two way street. Just because all the speech that needs protecting offends someone doesn't mean all offensive speech should have protection.

You really think this is solely an engineering decision? I'm guessing this is just as much if not more a business decision. We could have real world testing which is expensive where unexpected quirks and flaws could be revealed or we could have simulations which are cheap and quite confined to whatever it is the scenario is testing. Everyone in suits would go with simulations, while engineers know that models are abstractions and simplifications of reality.

Don't get me wrong, I'm sure they do a ton of simulation and regression testing and as a design tool it's invaluable. To use a car analogy I really doubt cars come rolling off the assembly line without some prototyping and real world tests first though. Remember that those affected by regulations tend to have really deep economic interests in skirting those regulations as much as possible.

If it's a big shop with tons of review it won't prevent this particular product from being a lemon. I recently had that happen to me on eBay, 99.5% approval rating and >100k feedback score but product was real bad. They delisted it after I complained. At any rate, I wish Amazon would split it into "Product reviews" and "Vendor reviews", because a lot of the feedback is about bad customer service that's entirely irrelevant if you buy from a different seller.
