  1. Re:Fishy... on The Leap: Gesture Control Like Kinect, But Cheaper and Higher Resolution · · Score: 2

    video measuring CAN really be that precise (given the right sensors, lenses, calibration and algorithms). A servo controller using camera's - see what (amateur) robots can do these days merely on "sight".

    Why haven't you heard about such tech yet - there are various problems when applying this to your specific field
    - Nobody has made it yet (well they have, but not repurposed for your machines)?
    - Your machines are 100k+ as you said yourself, your boss is not going to throw those out within 3 years and those machines have no place for such newfangled tech yet.
    - There are many situations where 'sight' only may not be a good fit (high speed metal cutting). And when your new tech only solves one very specific problem it's not worth investing in.
    - Those markets have already entrenched themselves with specific solutions and there is little external pressure to evolve the product any further and there is a quasi-monopoly on the end product and all it's options. Similar to cars, even though we have $5 GPS receivers in bulk and $50 all-in-one GPS devices retail with lifetime map support, the built-in GPS option for a car is still $500 (or more) while all they do is just pop in a GPS receiver on the CAN (or similar) bus.

  2. Re:No win win? on Who's Pirating Game of Thrones, and Why? · · Score: 1

    I doubt the show makes much of the revenue from the actual airing of the footage, they make money from the box sets, the merchandise and everything surrounding the franchise. Do you really think that HBO will cancel the show? The producers will just shop around some other channels who will most definitely be jumping to buy it and air it on non-premium channels.

  3. Re:A week? on Who's Pirating Game of Thrones, and Why? · · Score: 1

    Why can't they just put it online, on demand, you know like the "pirates" do? There are several issues with the antiquated methods:
    a) You can't record HBO shows in my neck of the woods (even though it's the US) - the DRM prevents the Cable DVR from recording and my personal DVR can't decode encrypted channels (legally). So you're stuck watching at particular times or ... pirating it.
    b) HBO shows don't seem to appear on Hulu or Netflix or any other on demand online distribution channels
    c) I cancelled cable and now pay only for cable internet + hulu + netflix + amazon and I can get pretty much anything I damn well please, if I can't, I get TED (The Episode Downloader) to download it for me. I would gladly pay for HBO on-demand if they offered it for say $5/month (which what HBO is at most worth for the 4h/month of entertainment they offer).

    Give us unrestricted IPTV and the world will be way better off, pirating will drop at least 90%, air the damn thing every 4 hours if you really want to stick to a certain hour.

  5. Re:The solution is.. on W3C Member Proposes "Fix" For CSS Prefix Problem · · Score: 1

    The CSS rules specify that the last one overrides. So they're still following the rules. They're aliasing a number of -webkit- prefixes because some developers (apparently you) thought that developing for -webkit- gave them good enough results but then the content wouldn't display in Opera or other browsers.

    Why the hell would you want each browser to have a specific color? Your website should look the same regardless of browser, that's what CSS and HTML is for. As you see the example, if you want to use -webkit-foo because it gives you certain options that's fine, but also include a standard foo so that your content gets displayed on non-webkit browsers.

    The prefixes are only there for certain functionality that's not in CSS (yet), however full websites are being built with only these functionality. Opera is aliasing certain features, not so everyone can start using the webkit prefixes, but so that websites will work and hopefully eventually, those webkit prefixes will disappear and they can remove this hack.

  6. Could it be the movie is just badly produced? on Hobbit Film Underwhelms At 48 Frames Per Second · · Score: 1

    If the 'sets look like sets' and the landscapes look good then maybe it's just a bad production. Yes, things at 48fps look crisper but if you make a shit movie, the shit will simply be more accentuated.

    You can easily cut down from 48 fps to 24 fps, just remove half the frames and double the length each frame is displayed. Will it look better? I doubt it.

  9. Re:Well, there you have it on Is Stanford Too Close To Silicon Valley? · · Score: 1

    It makes sense if you compare it to CS. CS is not about running software at peak efficiency however, it's about the theory behind our programs, computers, algorithms etc. So if an MBA is looking at the theory behind our businesses, MBA's should really be employed as consultants, economists, think thanks and faculty, not running an actual business (usually to the ground) because in business theory, people can be calculated with certain properties in an equation, in real life however, these optimal situations never exist and you'll have to work with it.

    The problem is also that MBA's are not assigned to run businesses but usually to run business units regardless of their skills or knowledge in the operations of the business unit (for example IT, HR, Sales, ...)

    Exactly. The *AA and their government goons have never cared about process. Same when you get arrested under false pretenses, the establishment gets off with a 'sorry' while in the mean time you lost your job, lost relationships and regardless of conviction you have a record that keeps influencing whether or not you'll get hired in the future and whether or not you keep getting re-arrested and strip searched for simply existing.

    These days, the legal system simply has so much cruft, overbearing laws and process hindrances that simply the threat of getting arrested is enough to make you think about complying with whatever they want, getting arrested will give you perpetual problems in your life and getting convicted even if overturned later will make you an outcast.

    - I have a Visonic SecureLinc 2 Wireless device. It's basically a DIY alarm system and it runs Linux, you can buy as many sensors and type of sensors as you want. It can send e-mails, place phone calls, send SMS, has a web interface, you can telnet into it etc. it's very easy to set up. It's also compatible with companies like Alarm Relay that monitor the Visonic for about $10/month.
    - I have a couple of IP camera's with ZoneMinder. ZoneMinder is buggy and flaky if you want high definition feeds but once you've got your magic configuration where it stops crapping out you're golden. I also learned that b/w pictures are just as good as color and that many camera's will ignore most of the options sent to it.

    It basically wipes the decryption key from any memory on the device. The key is not stored with Apple and I doubt Apple has a 'universal collision key' on their encryption as they use RSA if I'm not mistaken which AFAIK doesn't have a universal collision key. Same goes for Android/Google and most encryption, encryption with spare keys is easy to detect and crack.

  17. I think your issue is data integrity on Ask Slashdot: How Do You Manage Your Personal Data? · · Score: 1

    The physical problem has already been solved. Buy x number of x TB hard drives and put them in some type of configuration where they are all accessible at once. The problem with (desktop) hard drives is that statistically for every xTB you read an unrecoverable read error will appear. I manage over 100TB right now at my job using enterprise grade systems and almost monthly we have the system reporting a URE. The solution for that is checksumming. ZFS works great as does BtrFS and it keeps your data intact or at least reports what is bad about it.

    "File system errors" are simply unacceptable, you either use a very shitty file system or as said, there is a bad block somewhere on the hard drive causing you issues.

    Not all MRI is NMR. MRI can be purely magnetic using supercooled conductors and lots of power. These are the ones used on humans.

    NMR are usually the higher powered siblings of MRI systems with usually very small bores and really, really strong fields (up to 21T) usually used in spectroscopy.

  20. Re:I don't think you mean 17T! on Record-Setting 100+ T Magnetic Field Achieved At Los Alamos · · Score: 1

    Nope, 17T for tissue samples and small animals is correct for a very small bore size (coils available between 1 and 10mm) these are usually NMR though. Resolution is dependent on your coil and what you're trying to do but can be anywhere between 0.05-0.2mm

    7T is commercially available for human research which gives a resolution of .1mm. I think 3T for clinical is about the standard for new installations in the better hospitals, 1.5T for cheap, mobile or open (half) systems. You can get a small .5T for a little over 100k if you want one at home. It's almost cheaper than having to pay the copay.

    The no tattoos is because old tattoos and certain types of tattoos (if you got them in jail) are made with ferromagnetic ink (thus invalidating this patent). They can heat up and cause discomfort, even slight burns because of the currents induced by the magnetic field.

    The breathing problem is simple claustrophobia maybe you also had vertigo (I get vertigo after about 15 minutes in a 3T MRI) causing you to panic. There are no real "airflow" problems in an MRI, usually it's fanned which they can control.

    The "face shield" or as we call it "head coil" is the part that makes it actually work. Depending on the type of scans you do and the local setup there are a wide range of possibilities as far as making you comfortable, everyone has to offer adequate ear protection, most venues will offer at least music, masks etc. Some older people actually fall asleep in them. There are also places that offer video or personalized media and much more.

  25. Re:Makes sense. on AC and DC Battle For Data Center Efficiency Crown · · Score: 1

    In electrocution it's high currents that are dangerous (causing burns), not necessarily potential (voltage) although at a certain point, really high voltage does start to become an issue (breaking down tissue) - I think the threshold is 600V.

    Another side effect of high current DC electrocution is electrolysis inside the body, your muscles could rip or break bones because they're continuously 'powered' (with AC the voltage goes back and forth passing through zero (no power) frequently which causes the typical shaking that goes on).

    The thing is that for low-power (200V) AC or DC, DC is safer to use at the same current levels in case of electrocution. The problem with low-voltage DC is that you need to push a lot more voltage if you want a certain output on the other end of the line (the losses are greater). High-voltage DC (10kV) is however preferred for long-distance power transfer.
