    As always, would love to see it, as it's such a versitile material, and a shame that it has been mostly used as a whitener. On the other hand, if refining it makes the price of titanium dioxide go up, what are Oreos going to use?

  2. Re:Miracles Required? on The Replacement For the Battery? · · Score: 1

    Bigger issue is whether there is enough of the raw materials needed to produce their product on the scales they claim. Short answer: no. Barium isn't a problem, though it's energy intensive to refine, but Titanium supplies are pretty tight, and mostly eaten up by aerospace. Now, maybe they can start with refined TiO2 (which is cheap), and skip the pure metal stage, but I would want to see the synthesis and yields first.

    Iron-Phosphate is much more probable as a battery material, as it's available on the scale needed for automotive uses. Even if the above works, it will probably only be laptops and phones, and then only in places where sudden capacitor failure isn't a hazard.

    Hope I'm wrong, but this is probably a great system that works in the lab and is useful on a small scale. However, VC's want to hear that it's the cure for everything, so there it is.

    Years ago my copy of Kruse's "Data Structures" came with examples of how to do all the then-hip dynamic data structures (linked lists, trees, etc) in languages without pointers. This became useful when writing high-level Fortran-77 programs, as it allowed moving beyond Gomputed Goto and Arithmetic If for algorithms. In the same vein "Numerical Algorithms" (Teukolsky, Vettering, et al.) showed how to get decent array performance and add various oversights (such as complex numbers and complex arithmetic) to C-type languages.

    >>>I see this ending up as an effort to shoehorn concepts unique to one language to another language (building web sites in COBOL *shiver*).

    I once saw a series of cgi-bin routines written in Fortran-77 because that's what the web-site designer knew, and the schedule was too tight for her to learn Perl in time. (for those of you who started programming after compiled languages gave way to Python/Perl/Ruby/WombatCode6000, get a copy of G77, and try to compare two strings of different lengths) It's no big deal; given enough time one Turing-complete language can accomplish the same work as any other Turing-complete language. It's just the degree of pain you're willing to endure that's the limiting factor.

  12. Re:momentum on Why Do We Use x86 CPUs? · · Score: 2, Interesting

    The time I saw the runtime halved, it was a piece of code that had been rearranged to run well on early-90s Cray/Alliant vector machines. Dusty-deck fortran that grew up on VAXes or IBM mainframes doesn't do nearly as well, though I still can generally get 15-30% vs. g77. I can also get wierd bugs, as much of that code depends on, *ahem*, "features" left over from Fortran-66 which have since gone away and modern compilers (which are really F90/F95 compilers) don't support well.

    Personally, I'm sorry I won't be getting XServes with Power6 processors and 64-bit XLF, but price/flop for x86 isn't all that bad.

    Btw, my informal testing so far is showing that on PPC GFortran is about 12% slower than XLF for 32-bit code, which makes it significantly faster than the commercial competitors. A group that provides one of the packages I use (3/4 million lines of F77) recommends GFortran for building the 64-bit AMD version, for reasons of both speed and stability. So, it's getting better, but since I don't use C I don't know how much improvement GCC is showing for numerics.

  13. Re:momentum on Why Do We Use x86 CPUs? · · Score: 4, Interesting

    If you're dead-set on using GCC, yes. Alternately, if you use the native compilers which only have to support a fairly narrow architecture, you can get much higher performance. XLF on RS/6K and Macs was one example (capable of halving your run-time in some cases), IFORT/ICC on x86 and up, or FORT/CCC on DEC/Compaq/HP Alpha-Unix and Alpha-Linux were others. Currently GCC is not bad on almost everything, but native-mode compilers will still tend to dust it, especially for numeric work.

    Which brings back the other problem; not only are x86 chips cheap to make, but we have 30 years of practice optimizing for them. Their replacement is going to have to be enough better to overcome those two factors.

    In one room I have an Ikea Not (add the umlauts yourself) lamp, which is a pillar lamp with an upward pointing cheap shade. The plastic in that shade tends the light towards warm, so if you put a CFL in there then lateral light has a color close to what you expect, and the harsher cold light goes up to the ceiling, and is mellowed by reflecting off the warm-white walls first. A modicum of taste and skill decorating takes care of most of the objections.

    This is why I eat the original cost of such items, and use a ballpeen hammer and cold chisel on them when it's time to throw them out. Recovering anything from a memory stick where the storage chip has been ball-peened is going to be pretty difficult.

    Amortize the cost, and when you're sure you're not going to use it again, destroy. I figure that the 4GB SCSI drive that had held Windows and my tax software was a consumble after the upgrade to a newer drive.

    We used to have a mil-surplus filing cabinet at work that came with a huge combination lock on the front, and mil-spec instructions for destroying it in case our position was overrun. Something like nine steps which included smashing with a hammer, followed by a thermite grenade, followed by scattering the pieces in different trenches and incinerating again.

    I tried this once. It worked well under Win2K server, and the old licensing regime. For the new one, I paid almost as much in client access licenses as I would have for Windows XP licenses. As an academic shop, our costs were low enough for that to make sense, but for those of you in the real world, I'd be more careful.

    We ran into a couple of issues. The easily solved one was multiple copies of Office and Matlab are resource hogs. Get a large application server for those, and look into some sort of clustering. The harder issue was that some software actually sniffs to see if you're running on a remote session, and refuses to start if you are.

    To an extent, this worked great, as the desktops were more secure and easier to manage, while the Windows boxes transitioned from whatever Dell had cheap that month to multi-proc systems with hardware RAID, high-speed SCSI drives, and redundant power supplies. The only real lossage occurred for those users who needed high-performance 3d rendering on Windows, and most of them were easily transitioned to Linux equivalents. You may wish to consider getting WinTerms if you go this route, as those have fewer parts to maintain and fewer ways for employees to tinker with them.

    Quite seriously, you may wish to give Sun Sunrays http://www.sun.com/software/index.jsp?cat=Desktop& tab=3&subcat=Sun%20Ray%20Clients/url and Secure Global desktop http://www.sun.com/software/products/sgd/index.jsp /url a look. It will run from a Linux server, so it's on the right path from your perspective. One past job used an earlier version of this technology for student kiosks in the library, and it cut our maintenance headaches versus real PCs. Just a thought.

I forced an entire user community into Linux desktops once (it was a computational lab, so that actually made good, technical, sense), and the main result was a proliferation of Windows laptops so that people could run familiar productivity programs, for when the job didn't call for Fortran, MPI, and Mathlibs. In the end, it was good for my peace of mind (had I had my way and a larger budget, they all would have been running AIX), but the user-level aggravation, complaints, time for training, and debugging (oops, the last kernel revision whacked the 3d drivers again. Just a minute while I recompile the kernel module, upgrade the offenders, and reboot them. again.). In an environment not made up of physical scientists with years of Unix experience (even grad students had dealt with their Uni's Unices as Undergrads), it would have been an exercise in "How to Give Yourself a Nervous Breakdown".

So, Nexts weren't purchased, even though given the software and performance, they weren't out of line versus Sun 3/60, Apollo, etc, and SGI had to port everything to X in order to survive. We took a performance hit on every machine that had to run X versus the previous window-manager, had to add megs of expensive (early 1990s) memory just to not hear the disks whine, and generally gained very little in return for adopting this, ahem, standard. Then, if you wanted to see real death by toolkit, running Motif on a Vaxstation 3100/38 that had run smoothly under previous versions of X alone was a good example. We had a program that *somebody* insisted had to be Motif only, and the performance was so apalling we spent ~$15K on an Indy, just to be able to work. That VAX was perfectly fine (and would have still been useful if the programs the lab used had an X11-only, VWS, or even Tek-4107 interface), but it had to be retired due to a bloated toolkit.
