    Sure, there are nice free attempts, but you still have problems without your slow, memory hogging VM.

    You missed gcj, which eliminates both the VM and runtime compiliation overhead.

    Might as well screw deterministic memory- something more than necessary with realtime embedded systems.

    This problem is eliminated with gcj, as long as you know what you're doing regarding GC. There is also a real-time specification for Java, which was apparently used to program a sophisiticated Boeing drone. This was announced at JavaOne earlier this week. Finally, the Javolution library is a useful tool in this area as well.

    Maybe JIT moved Java from being fully interpreted, but it's still interpreted and "compiled" at runtime making it theoretically (a.k.a Javaly) and realistically on average always slower and more of a memory hog than unnamed alternatives, that's all. But, sometimes that's ok right?

    Apparently, in the case of VB, Perl, Python, Ruby etc. etc. etc. Besides, as I pointed out above, there are ahead-of-time Java compilers. (JET is a commercial alternative for Windows.)

    Look at how Java has taken over the desktop application market where that least matters. How many Java desktop applications do you run?

    Several.

    Can you tell it's Java?

    No, not in the case of Eclipse, Azureus or RSSOwl. Can you? (BTW Azureus is one of the top applications on Sourceforge.) Others are minimally identifiable, but their interfaces are no stranger than Winamp or many other current applications.

    If programming will always be hard, one might wonder what skeletons in the closets Java fanatics have at the price of conformity to an interface. Java version incompatibilities, buggy VMs, oh my.

    As opposed to (just to pick my favorite whipping boy) C++ compiler incompatibilities, memory issues, third-party library incompatibilities, and fragility?

    Java isn't perfect. I'm personally interested in seeing a truly open language developed which is more suitable for HPC, numerics and realtime, and leverages the best features of Java and C#. Until then, however, I think Java is a very good alternative for many projects, large and small.

    Actually, you need to hollow out the walls, and then place an insulated airtight container inside (a thermos) so that the heat stays away from the asteroid.

    The shell must be made airtight (not a big problem), but the asteroid is already a thermos, being surrounded by vacuum. The skin should be designed so a) it is largely photoelectric for electricity generation and b) has a mechanism for varying the energy radiated from the shaded side. If the photoelectric coating is high enough efficiency, that will cut the amount of heat that's absorbed by the object. A reflective outer coating may also be used. Also, the orbit can be chosen so that it spends as much time as needed, up to 50%, in the Earth's shadow to ameliorate heating issues (note that in a polar orbit, such habitats could be sunlit 100% of the time). In all, heat control isn't that difficult of an issue.

    In fact, thinking a bit more, one could envision the following setup: a panel on the sunward side, which is essentially a large solar collector, coupled mechanically to the habitat by two beams which connect to bearings at the poles of the habitat spin axis. The beams extend back beyond the habitat to where the heat exchanger sits. The power panel would not only provide power for the habitat, but would power gyroscopes to keep things oriented properly. The power panel could be oriented dynamically to allow more insolation of the habitat to occur if needed, keeping the interior temperature at desired levels.

    And plenty of reading material and lots of things to do.

    Part of what makes apple successful, is that they limit the hardware that they run on. If and when they start supporting more than just their own hardware (think white box PCs), you can expect the same problems to plague apple.

    This is just BS, so I'm in the right thread (heh).

    First of all, even in Windows the market-leading hardware is well supported. What percentage of PCs (where the user actually cares about sound) run Creative soundcards do you think? We are down to essentially three video chipset manufacturers also, Intel, NVIDIA and ATI. On AMD systems, there are only two.

    If Apple wanted to support whiteboxes (which it evidently doesn't at this point), all it would have to do is specify the Intel chipsets/motherboards it supports, and let NVIDIA, ATI and Creative supply drivers. Scarcely rocket science (it's called a "supported hardware list" just like the one at the Red Hat site). Unlike Linux, which has the goal of supporting legacy hardware, Apple can be much pickier about what hardware OS X might support.

    On the AMD side, things could be even simpler if Apple wanted white box support. If I were Apple, I'd make a deal with NVIDIA and Creative, and only support nForce/GeForce/Creative based systems. That is the direct opposite of a "support nightmare". NeXT used to support WAY more hardware with many fewer resources, and do it near perfectly.

    Apple may eventually sell a whitebox version of MacOS X (for $500 or more dollars it'd be quite profitable). If it does it'll be fairly painless for Apple and should work very well.

    In the meantime, I'm interested to see what Apple does with its hardware line as it transitions to Intel. I think a Pentium-M Powerbook sounds very appealing...and it should triple-boot.

Second, there is a complete x86 port of the BSD portion of the OS, called Darwin. Third, Macs already use a lot of PC infrstructure like PCI, USB, and AGP video cards, so drivers should port easily. Fourth, there has long been a rumor that Apple internally maintains an x86 port, which I regard as very reliable, since Apple would be insane not to do it.

    It would technically be trivial to make MacOS x86 only boot on Apple-branded hardware, so lockin isn't an issue. In fact, one very practical dongle would be to include a G4 chip to run legacy code...

    I would HOPE Apple would be smart enough to use AMD chips, since I feel they're technically superior and AMD has a strong roadmap ahead.

    I also hope that Apple will go forward with a dual-architecture strategy that will let PowerPC and x86 compete. That would be healthiest for the computer industry, but I doubt it'll happen - it's too much of a mixed message, and higher costs for Apple.

    Truthfully, all in all I hope this rumor is BS, since Apple finally seems to be gaining some traction and this kind of maneuver will kill sales until the x86 boxes are released (plus I like the idea of PowerPC Macs really) but I guess we'll see.
