  1. Re:TV screens still have a long way to go on Mind-Blowing Interfaces On Display At SIGGRAPH 2009 · · Score: 1

    The problem is that the displays create desaturated color. They don't create single spectral line (single wavelength) but rather a large band around a peak. This limits the gamut of the system, along with the recording and transmission equipment. http://en.wikipedia.org/wiki/Gamut shows how limited a NTSC standard, and typical CRTs are. One solution is to use sources with more nearly monochromatic ranges, which is what the upcoming laser based displays hope to do. A possibly easier alternative is to have more color channels spread around the perimeter of the cie color space. http://en.wikipedia.org/wiki/CIE_1931_color_space

  2. Re:Maybe it's a good thing, if prices fall. on The Downsides to Digital Distribution · · Score: 1

    My dynamic systems sixth sense says the price of used games will asymptotically approach the price of new ones in this situation. The coefficients will vary widely depending on the starting price, number of resales available, and whatnot. But I would guess that at some point the used price would be around 10% less than the new, similar to how gamestop can sell used games for only a few $ less than a new title if it is somewhat recent.

  3. Re:Math ftl on Visualizing False Positives In Broad Screening · · Score: 1

    This is why the word "accuracy" no place in a discussion like this. Everyone should read http://en.wikipedia.org/wiki/Sensitivity_and_specificity to understand how a screening test should be evaluated. In your case you are describing a test with 0% sensitivity and 100% specificity (it never shows false positives but always shows false negatives). An optimal balance between these two can be selected using an ROC http://en.wikipedia.org/wiki/Receiver_operating_characteristic for a real test.

  5. Re:Dear Sony on BD+ Resealed Once Again · · Score: 1

    I wonder if it is just an NVIDIA driver issue. But that is clearly misleading advertising if the thing can't be used to display BD over the HDMI port. Sorry, I also assumed a pavilion was a desktop, no idea idea why, so thats really crappy of them.

    I didn't realize that was a laptop. For some reason I recalled Pavillion was a desktop model, but I see I was incorrect. So yea, that kinda blows.

  7. Re:Dear Sony on BD+ Resealed Once Again · · Score: 1

    Sounds like its NVIDIA's fault for not providing an HDCP compatible HDMI port. It usually says right on the box of the card if it supports HDCP. Although I've never purchased an HDMI video card, I think most of the new ATi cards support HDCP. You can probably get one that works for under $50.

  8. Re:Here's the real question on BD+ Resealed Once Again · · Score: 1

    You are comparing apples to oranges. A compressed DVD format movie is typically 1.4GB but can be up to 8.5GB on disc, usually 4.5 for single layer though. Similarly a 1080P BD dump may start as large as 50GB but is usually compressed down to 8.5GB. 720P can easily be compressed to 4.5GB when scaled from BD source. So really the question is Uncompressed do I want 50GB or 8.5GB or compressed to I want 8.5GB or 1.4GB. The also standard def BD rips weighing in around 2GB that at least dont have de-interlacing noise. Since I used to only download the dvd isos at 4.5GB getting a 1080P at 8.5 is really no big deal.

  9. Re:OT: Paid by word? on Microsoft Trying To Patent a 'Magic Wand' · · Score: 2, Insightful

    I was a co-inventor on a recent patent application and I can attest that pretty much all patents are written this way to make them as precise and robust as possible. Sometimes these phrases like "a collection of sensors" might refer specifically to a prior description or figure. Anyway, this is totally typical, and no the lawyers are not paid by word.

    Cryptic is working on it. It will be based on the same engine as Champions Online, which today has an official release date for 7/14 which is a very good sign for progress on the Star Trek MMO to really get up to speed.

  12. Re:Until... on VLC 0.9.9, The Best Media Player Just Got Better · · Score: 1

    This is in case you get a corrupted download, you can redownload just a part instead of the whole thing which is very important for video which are typically large downloads (anywhere from 175MB for a 30min tv show to a 40GB Blu-Ray rip). This is how every single thing I get on Bit-torrent (private tracker FTW) is packaged.

  13. Re:Solution on AT&T Has Begun Issuing RIAA Takedown Notices · · Score: 1

    Nice thought, but the names of the artists and songs themselves may be copyright, so you have infringed by using their name to popularize your own shitty shower singing. Technically, it would be a different violation, but you get the idea.

  14. Re:I repair video games for a living on Increase In Xbox 360 E74 Problems · · Score: 1

    Your last point is very good. I was going to reply to another comment about someone replaced his optical drive every 18-24 months because I have been using the same dvd-rom for over 6 years and other optical drives for long periods. Then you reminded me that I can probably go for weeks without ejecting a disc or even reading from it. Similarly all 3 modern consoles sport downloadable games now. I personally own a PS3 and after the initial install of disc games it doesn't seem to read the disc all that much and you can tell when its thrashing. So, I think they get quite a bit more wear than PC optical drives, but not "EVERY SINGLE SECOND" as you said.

  15. Re:it's about the cpu-time on Believable Stupidity In Game AI · · Score: 1, Insightful

    Agreed. Single player focused games (where AI is important) should be able to take advantage of modern multi-core cpus to let AI shine without interfering with graphics and physics. That and give me the option to set the AI the same way I set graphics options for performance or detect optimal configurations like many games do today on PC.

  16. Re:I want a PS3 on Game Publishers Pressuring Sony For PS3 Price Cut · · Score: 0

    Does this actually work? I thought without the drivers the controller would only get a trickle of power compared to charging on the PS3. I honestly haven't tried running the controller all the way down and plugging it into another device like my desktop pc thats always on to see.

  18. Re:Not surprising on What to Fight Over After Megapixels? · · Score: 0

    As for low light response, the easiest way to get better low light response is to use bigger optics.

    This is not completely true. The quantum efficiency http://en.wikipedia.org/wiki/Quantum_efficiency of the CCD (basically the number of photons to get a measurable change in output) is a known factor, often rated for scientific sensors. Improving this allows for better low light sensing without having to increase the size of the optics or use better coatings to increase the light captured.

    Read the description, "You can, if you wish, turn off that press 1, press 2 option, so when the phone rings, you can just pick it up and start talking." Agreed that old analog tech you can hear the voice mail as it is being left, but that doesn't work well with cell phones and more modern voice mail systems.
