  1. Re:Woah.. on Cheap Blood Clot Detection Device · · Score: 1

    What are the running costs like on a CT machine? If the thing has a high utilization anyway then it's a moot point, but if the ROI depends on how much it gets used, wouldn't it make sense to use it as much as possible? Of course if it costs an extra 100k or something per scan then it isn't such a sensible idea...

  2. Could you scan a whole head? on Cheap Blood Clot Detection Device · · Score: 1

    Could you scan a whole head with a sufficiently bright torch in your mouth? Maybe you'd need that transparent skin mod from a while back too... It's be kind of strange having your eyeballs illuminated from the back :)

    I wonder if the same tech could also be used to detect DVT too? They could build it into the X-Ray machine at airports so that on the way in and out and a bell would ring if it found a blood clot in your legs (it would make sense to detect them on the way in too!)

    Yeah dammit. If those pesky plants were more efficient in converting sunlight to stored energy instead of letting it get converted to heat or reflecting it we wouldn't be in this damn global warming mess in the first place.

    The cooperative price fixing works because they all have about the same manufacturing costs and about the same product specifications, and collectively stand to make more money by doing that than starting a price war. If one RAM manufacturer suddenly had a breakthrough that meant they could produce memory at 1/10th the cost, I'm pretty sure that they wouldn't hesitate to drop their price to (just) below the manufacturing costs of their competition.

    It kinda goes without saying that having 2 monitors when you only really need one is a waste.

    An advantage of 2 physical displays is that instead of printing a design spec or whatever to a printer, you can just open it up in the second display and start coding. I'm not sure how many pages you'd have to not print to offset the manufacture and running costs of a second monitor though...

  12. Re:Did the same thing.. on Using Two Monitors Makes You More Productive? · · Score: 1

    We recently sold one of our clients (accounting firm) about 100 flat screen displays, quite a few second (or dual) video adapters, and a few computers (to replace ones that couldn't be upgraded) to give their 80 or so users 2 displays each.

    Anyone with a laptop now seems to have an additional display hanging off it now too.

    It is definitely catching on.

  13. Works for me on Using Two Monitors Makes You More Productive? · · Score: 2, Interesting

    I spend a reasonable amount of time in RDP (Remote Desktop) sessions to clients MS Windows servers. Things are better these days but a few years ago we had a lot of customers on fairly slow connections, and RDP, being the wonderful protocol it is, wants to redraw whenever you bring it to the front.

    So I would connect, log in, then wait for a a minute or two for the screen to draw (remember, I am normally connecting in to solve a problem, so performance is often much worse than normal!) then slowly try and figure out what is going on.

    What made it horribly sucky was that I couldn't minimize the RDP window while it did it's thing, otherwise it would just start to redraw again. With a second screen I could just put the RDP session there and let it do its thing!

    Just recently I have been porting an older C++ application to C#. I have the source code for each application on each screen, way faster than trying to flip between them on a single screen.

    The nice thing is, this works so well _because_ they are two separate screens. Having one screen that was twice as wide just wouldn't be the same (unless it functioned as two screens of course :)

    My setup is my 15" laptop display and a 17" CRT, both running 1024x768 resolution. I'm almost thinking I should track down a USB VGA adapter and run a 3rd screen. Performance might suck (being USB instead of PCI) but i wouldn't be doing anything on that display where that was an issue.

    Hmmm... here's a more interesting question. At what number of screens does productivity start to drop? I guess the answer will depend on what tasks you are doing but it would sure make an interesting study... I'm imagining 3 screens across and 2 screens high as a starting point :)

  14. Re: Refrigeration on Solar Power-Cell Breakthrough · · Score: 1

    Reverse cycle air conditioners are moderately popular heaters over here (Australia)... but the thing that always astonishes me is that the other side of the heat pump is outside!

    Almost every house will have a hot water heater of some description, and a refrigerator. That's one device that can probably make use of the 'free' heat when your aircon is being used in cooling mode, and another that can make use of the 'free' cold when it is being used in heating mode.

    Then there is the refrigerator itself... in winter it helps keep the house warm, but in summer there is all this heat just being dumped into the house!

    I wonder how complicated a system of pipes and valves and a controller to manage it all would be?

    filing $25.000 for $800 worth material is SHIT, and RIAA behaviour.

    I believe that in Australia a private organisation cannot impose what amounts to a penalty/fine like that, they can only seek to recover the damages. As the quoted poster elegantly put it, $25000 is a stupid amount to try and claim. Given the roots of Australian law, perhaps something similar could apply in your case?

    While all of this is very interesting and educational to discuss, anyone replying to you on slashdot is almost certainly not a lawyer (lawyers are known for their black, black hearts, and are unlikely to be handing out free advice on the internet :). The _only_ legal advice you should take notice of on Slashdot is "Don't listen to any legal advice anyone gives you on slashdot - get a lawyer!" (now there's a paradox!)

  23. Re:AACS "Improvement" on Hacker Defeats Hardware-based Rootkit Detection · · Score: 1

    This suddenly reminded me of a trick on the Commodore 64. The 6510 processor had the first 2 bytes of memory space hardwired to an 8 bit in/out port (mapped to physical pins on the cpu), and an 8 port direction register to control the inny or outyness of the other byte.

    As such there was no way to read those two bytes, ever, as any attempt to access them by the CPU would always read the i/o port bytes instead.

    Then someone figured out that you could view them by mapping screen memory to that location (eg starting at address $0000). And, you could then use the hardware based sprite collision detection in the video chip to read them (collision = 1, no collision = 0).

    I'm not sure that there was ever a way to write to the memory under the i/o port bytes, so the hack wasn't really very useful, but it does illustrate that you should never say never... and as a system gets more and more complicated, there is more and more opportunity for loopholes like this to creep in.

  25. Sounds reasonable on Possible Cure For Autism · · Score: 1

    Look at the number of claims that Autism was caused by immunisation/vaccination injections or a food allergy or amalgam(sp?) fillings. Some parents claim that their child was perfectly normal before these events and then very rapidly developed what later turned out to be Autism.

    It makes some sense to me that if these children had a 'fragile' metabolic makeup then 'shocks' like the above events could lead to these sort of brain malfunctions (eg of the part of the brain that automatically processes social cue's).

    It might also explain why the incidence of ASD's are so much higher these days (better detection aside)... I'm guessing that the average diet these days has quite a different fatty acid makeup than 20, 50, or 100 years ago...
