    The article talks about the challenges about designing a robot for the home that is fun, useful and safe. Fun is doable. Safe is doable. But useful? Really? I'm sure that such a device could be put to use, but does that make it useful. In college, we built bookshelves using cinder blocks and lumber, but I would not hold out that cinder blocks were "useful" in the home (outside of the actual construction of the home), just because we found a way to use them.

    Obviously, we have numerous things in our homes that we enjoy and want, but are they truly useful, in the real sense of the word? Put differently, what makes something useful? If I hang an ugly picture over a hole in the wall, that ugly picture serves a purpose and in that specific instance is useful, but does that mean all ugly pictures are useful?

    When designing a robot for the home to be useful, what characteristics would it actually have? In other words, how would one measure whether something is useful or not objectively? Think of "Zen and the Art of Motorcycle Maintenance". Instead of what is "quality," what characteristics make something "useful"?

    Unless they can convince the wider Linux community to adopt some of their technologies, Canonical is basically going to end up forking the platform. If that happens, it will be a fairly major step backwards for Linux on the desktop since developers will be on the hook to adjust to supporting not just multiple packaging systems and multiple library versions, but also multiple incompatible core system API's. Essentially Ubuntu will no longer be "Linux" in any way that matters to developers and all the support for Linux out there now will either die or just switch over to being Ubuntu specific and I don't see how that benefits anyone in the community.

    Forking the platform, you mean like Apple did with BSD and Google did with Linux? I think Canonical isn't interested in having a linux distribution. Just like Apple has OS X and Google has Android, Canonical plan is to have Ubuntu as the operating system.

    Canonical, however, doesn't even have a market for many of it's ideas let alone being first to market in the markets it is trying to break into. So, if they can't be first to market with a new concept or idea, and they want to mirror Jobs/Apple's success, then they need to dramatically improve what is already out there. So far, they have not been able to do that, and it appears that there efforts aren't even being focussed in that direction.

    I think Shuttleworth has just decided (probably correctly) that he can't make any money on the desktop, but mobile is still a possibility.

    It is highly doubtful that he can make any money in the mobile sphere, that is pretty well decided now, too. He probably stood a better chance with the desktop, particularly after Windows 8.

    The Unity interface and now this are an attempt to compete with Android.

    If the goal was to compete with android, they should have gone KDE. KDE active is a much more attractive development environment and much further along than Ubuntu's mobile offerings, which don't even use the standard Unity interface.

    I abandoned Ubuntu for my desktop when Unity came, but I think I might actually like it on a tablet or phone. Anyway, I'll try to keep an open mind when the devices actually come out. I hope one of non-Android Linux phone efforts finds a niche, whether it's Ubuntu, Jolla, Tizen, or Firefox OS. If Shuttleworth can pull it off, then more power to him.

    Study after study shows that Unity does not work well on a tablet/touch device. It only looks like it should work, but all of the apps are mouse centric. The problem for Canonical going mobile is that most of the apps in their repositories, which is a large selling point (even if free), won't work on mobile. So from the very start, they will be competing with Apple and Android who have a huge head start and even Microsoft who while a very distant third is lightyears ahead of Canonical.

    As I said earlier, they should have gone Plasma Active. If all of the resources that they dumped into Unity and now their mobile offerings had been used to further that project, they would have been to market earlier and had apps ready to deploy. Instead they chose to go their own way, which is their right, but not necessarily the wisest business decision as even Microsoft is late to the game.

    If you are going to need years of hovering for this to work and you are going to have to reach the asteroid while it is still years away, so you have time to launch a rocket and travel to it in time to make a difference, That means, first you are going to have to be able to detect said asteroid while many decades away, if not possibly a century or more.

    Now, lets say there is an asteroid detected early enough that this might work and that it is relatively small enough where it would make a difference, say the size of a football stadium. Assuming it is mainly solid rock and iron, exactly how much fuel is going to be needed to hover long enough to make a difference. Then once that is known, how much fuel is it going to take to transport the hovering fuel there in a timely fashion. And finally, how much to get it out of earth's gravity well. Sounds like one pretty damn big rocket is going to be needed, just to transport the fuel.

    Of course, if it works and it would safe earth, that would be worth it. OTOH, we still have to get past being able to detect it far enough away where there would be time to get there and do all of this hovering.

    Now, on the other hand, instead of a football stadium, the asteroid is the size of a volkswagen (which would be far more feasible to divert in this manner), and it is on the right trajectory where it will hit the earth's atmosphere at a steep enough angle that it will penetrate it instead of glancing off, we will never know in time to do anything about it, because at that size, it won't be detected until it is too close to alter the trajectory.

    The short version is that we often think of evolution as being the survival of the fittest, where the strong and the dominant survive and the soft and weak perish. But essentially, far from the survival of the leanest and meanest, the success of dogs comes down to survival of the friendliest.'

Humans, weren't the fastest, we weren't the strongest, we didn't have the longest fangs or claws. In every way, we were inferior in some major aspect to the other predators. He goes on to say, however, that what made humans survive and dominate is their innate ability to cooperate. Above all the other animal species, the ability for humans to cooperate with each other outweighs the deficits in our other competitive traits.

    For Darwin, what made humans the fittest at survival was our ability to cooperate with each other. It was others who took the survival of the fittest and twist it into what we talk about today with it. Cooperation is not unique among humans, it just reaches its highest expression.

    It would seem that increasing the on board cache to an un-godly amount would be just as effective and adding a battery or cap to ensure writes were performed if power goes out would minimze the risk from SSD failures.

    We actually ran those back in the day. 1GB SCSI disks with 1GB memory on top of them. Expensive as fuck, but boy would they scream.

    Back in the day they were expensive, but today, they aren't or wouldn't be and they would probably still outperform SSDs which are slower on writes than volatile memory. That said, SSDs would do much better on power consumption, although, with a big enough cache, you could actually spin down your drives and only occasionally bring them up for writes, or run them at a lower speed than even 5400rpm.

    SSDs have their place, but I'm not sure high volume, high availability storage that is constantly updating is the place for them. Wear leveling has improved tremendously, but it still only postpones the inevitable.

    See the difference now? The "desreuctive force" of the astral body can't exceed the destructive force of a light net gently settling on the surface. Though if it doesn't work and it hits the earth anyway, yes, the net will be destroyed.

    But there is not light net gently settling on the surface, unless you are going to try and catch the asteroid from the back side, which of course won't do you any good. As long as you are approaching the asteroid from the front or some angle off center from the front, you have to deal with the inertia of the asteroid against your net.

    I guess it would be possible to land on the asteroid and somehow deploy your net running around the surface and at some point on the back side launch rockets in the opposit direction, but at that point, the rockets and cords attached to the net have to be able to deal with the inertia of the moving asteroid.

    Put it this way, prior to launching the shuttle, it was bolted to the pad, to allow it to build up thrust. If your methodolgy worked, everytime they launched the shuttle, the earth would have been nudged out of it's normal orbit. It simply doesn't work that way because there is too much mass involved (earth) versus the thrust of the rocket (shuttle). Catching an asteroid hurtling toward the earth in space would not be any different, other than whatever you are catching it with has to be able to withstand the mass and inertia or at a minimum get drug along for the ride.

    I think you may need to consider feasibility when coming up with your plans. It's a lot easier to just fly somewhere and hover than to land, or to make and deploy a gigantic asteroid net.

    That may be true, but while hovering, you are going to have to exert enough gravitational pull to offset the inertia that is already in place. While it is true that all bodies exert gravitional forces upon each other, in practice, there has to be enough force to actually do something. When we landed men on the moon, the gravitational forces between earth and the moon were altered, but not enough to change their positions in space relative to each other. Likewise, a rocket, unless it contains extreme mass, is unlikely to change the trajectory of an asteroid or comet because of the combination of the gravitational forces and the inertia. And, if said rocket does contain enough mass to effect this change, then how in the hell are we going to get it there in the first place?
