    I started writing a reasoned explication of the pointlessness and irrelevance of this whole story, but I made myself too angry with the uncritical "private space colonisation" fanboy mentality that says we'll all be living on Starship Enterprise in a century's time. To those people (probably everyone on this thread) I say this: turn off the damn Star Trek DVDs and get a life. Colonising space is an infantile fantasy.

    Full of sophomoric cynicism today are you?

    You sound a lot like the folks back when who said we'd never drive at 60 MPH 'because it will suck all the air out of your lungs', or the engineer who claimed that 'rockets will never work in space because there's nothing to push against'. Few people in 1900 would have predicted airliners, satellites, nuclear weapons and ICBMs less than 70 years later.

    Colonizing space is the only hope for our species to last more than a few more millenia IMO. It's good to see the visionaries pushing forward despite Luddites such as yourself.

    True, modifying the bits might lead to an easily detectable pattern. And any modification at all is noticeable when there are "normal" copies of the same image floating around. So let's assume that there aren't, and that you have a shared one-time pad available beforehand. Then you should be able to make the low order bits carry a message yet remain indistinguishable from random data. Which raises a question - what patterns are normally present in the low order bits of picture files? If the files you normally exchange have random lest significant bits, then you're in the clear. But I'm guessing it's not that easy for photographs and especially simple gifs with few colors.

    I've looked at quite a few PNG/RAW images. Often, photos have constant values for the low order bits over large areas. So, you're best off picking photos of natural things with high noise content (little sky or other uniformly colored items in the image). Also, the less information you inject into the image, the less it will affect it statistically.

    Write a simple viewer to display the low-order bit as black or white and you'll quickly get an idea of what I'm talking about.

    Well whatever method you use, unless you're making use of some hiding room in the format that's discarded as garbage data (like the space after a gzip file), then you won't directly increase the file size by using steganography. However, you would want to work with a larger image to begin with so you could fit more covert data in it, and that alone may be suspicious to anyone watching.

    A little quick analysis shows this isn't really an issue, for textual information. Think of a typical 1 megapixel image. This provides 1 million bits of storage, or 128K bytes. That's quite a lengthy message in text, around 64 pages. If all you need is "It's time to execute the plan!" (suitably encrypted of course) a much smaller image could be used.

    The tricky area in steganography is that the cutting edge approach is to embed data in lossily compressed JPEGs using DCT coefficients. Apparently the change in DCT statistics can be detected in many cases, so it may not be too useful. However, I'm not too sure of the precept that losslessly compressed images are rare or obviously steganographic. There are plenty of PNG and RAW photo images available on the Net. (BTW, swizzling the low-order pixels as the grandparent suggested is an obvious clue that the image has been altered, and is a possible steganographic image.)

    Sorry I got busy and forgot to check this for replies. I hope you notice it. ;-)

    The majority of knowledgeable geeks I know of don't really think that way. More of them think that way than the non-geeks, as a rough percentage, but the lack of hardware, the lack of software and the overall closed-platform that they had been stuck on for so long makes them less than desireable. That are not clearly one of the most flexible computers, they have a lot of limitations along with their advantages.

    You are conflating MacOS with Mac hardware. Mac hardware runs MacOS, Windows (either virtual or native), and Linux (either virtual or native). So, there is no other computer that you can buy that is as flexible of a software platform than a Mac. Sorry I wasn't more clear, though I think you're off on your other conclusions too, see below.

    Apple expects peoples wants and needs to adapt to their computers, you find that is a lot less common in the PC world.

    This isn't really true any more, though I'm sure it'd be nice if Apple had even more models. What you should really look at now are the Mac Pros, which are highly configurable (something like 2 billion possible configurations from the Apple Store, and a lot more if you take into account third party hardware). I'd like to see a Core 2 Duo based tower at a lower price point, but that's the only big hole in Apple's lineup.

    1) You can build your own PC, can't do that with an Apple

    Since Apple is a hardware manufacturer, that isn't too surprising. You can't build your own IBM or Dell either. But yes, that is one area I'd like to see Apple change, I'd like them to sell their OS for a few hundred dollars to run on third party hardware using approved devices.

    2) Until recently, you could put MacOS and maybe wiggle a few flavors of *Nix or *Nix clones on a Mac, PCs had pretty much everything but MacOS, and some industrial-grade operating systems available for them.

    I'm not at all sure what you mean here. Current Macs run MacOS, Linux, Windows, and most likely any other x86 compatible OS (say QNX for example).

    3) There's a lot more software avialable for Windows for Apple, you can also find more or at least comparable amounts for Linux and BSD as well.

    Since Mac _hardware_ runs all of those operating systems (and runs most of the software fine in virtualized environments) I'd say you're off base here. Plus, since MacOS is POSIX, a lot of *nix software compiles and runs fine with no modifications.

    4) The majority of hardware/peripherials you find is labeled for Windows. While you can often use them on other operating systems (Linux, BSD, MacOS), the stuff that works on Macs is still a lot less common, probably even less common than that which will work on Linux.

    Yes, but the need for third-party hardware is reduced with a Mac. Plus, many things do work, for instance most Bluetooth, USB and Firewire devices - which is a big chunk of the market.

    I think Apple is going to see a big upswing in computer sales over the next few years as word spreads of how painless, fun, and powerful Macs are compared to the competition.

    The thing is, we tech "geeks" who actually know what we're talking about like Apple's products for the most part. Apple products also have some very tangible advantages, and Macs are clearly the most flexible computers on the market.

    I'm fairly well acquainted with gcj, and in fact it compiles a fair amount of standard Java without problems. There is also the Jet compiler which is ahead-of-time and fully compliant.

    So, it's certainly possible to do a good ahead-of-time Java compiler. Whether Java is desirable as the "next big general purpose language" is another question, of course.

    D is attractive if viewed as a superior C++.

    Maybe it makes sense for some resource-constrained settings like embedded systems, but there i've used Java straight up, satisfactorily. Granted, these are not life-critical systems I've built, but rather than compiling Java - or trying to - the better answer is to use a more appropriate language in those circumstances.

    There is a very big sweet spot for a language that's approachable, powerful, productive and efficient. With the advent of performance/Watt thinking, it makes no sense to get efficient processors and then throw away that efficiency on slow software. Of course, there are also applications where raw speed is very important; real time apps, simulations, games and scientific programs.

    C++ is widely viewed as less than desirable. It's good to have better, more modern alternatives going forward. Another interesting looking language is Dylan, though quite different in many ways.

    The one tangible thing that's been done to try and address global warming is the Kyoto Protocol. It is quite flawed, though, in that it gives exemptions to the countries which are most likely to be big polluters in coming decades. It would also impose economic penalties on countries like the US which are already doing quite a lot to reduce their environmental impact.

    If /.ers want to rally around a single approach that would be beneficial not just to human related global warming if it exists, but also to energy independence and reduced pollution, do whatever you can to advocate constructing new nuclear reactors here in the US.

    Apple has always touted OSX as a superior experience to Windows, and is continuing to do so.

    However, it is simply reality that many folks have Windows programs they need to run as well. Between Boot Camp and the various VM approaches Apple now has that option covered nicely.

    Linux malloc() is based on the glibc and is slightly brain damaged from my point of view, because it can't be properly overridden for debugging or dma operations (it has debug hooks but they aren't thread safe). OS X malloc() is a different implementation that actually supports multiple heaps and allows for the different heaps to have different allocation/release strategies.

    Regardless, GC is often faster, and also prevents mistakes that C/C++ coders often make.

    The other point about GC is that for reliable, long-running programs GC mitigates the issue of heap fragmentation, which can lead to irrecoverable program errors in programs using malloc() and cousins.

    GC technology is advancing rapidly, there are even deterministic GCs for RT use now.

    Object recycling is also often a good strategy, since you get "new" objects with no allocation/GC overhead.
