    A panda walks into a bar. He orders a sandwich, eats it, then draws a gun and fires two shots in the air.

    "Why? Why are you behaving in this strange, un-panda-like fashion?" asks the confused waiter, as the panda walks towards the exit. The panda produces a badly punctuated wildlife manual and tosses it over his shoulder.

    "I'm a panda," he says, at the door. "Look it up."

    The waiter turns to the relevant entry and, sure enough, finds an explanation.

    "Panda. Large black-and-white bear-like mammal, native to China. Eats, shoots and leaves."

    Most of the mistakes are going to be spelling errors, an omitted punctuation, et cetra. In most cases, those errors are mere speed bumps to reading, but don't change the substance of the patent...

    It's too expensive for monitor makers to tool up for a UXGA+ desktop display that most people wouldn't buy.

    Outside of specialty applications, most people wouldn't want such a high native-resolution display on a desktop monitor.

    That said, if you want to convert a notebook panel to be a desktop monitor, you can find custom monitor makers out there that'll do whatever you want... It just won't be cheap!

  4. Perhaps you need to adapt? on Dell Selling 30" Flat Panels · · Score: 2, Insightful

    The refresh methods of CRT's differ greatly from that of LCD's. Your eyes (or, rather, your eyes and your brain) are probably tuned to the CRT since you've been using that setup for a decade... Also, try adjusting the backlight intensity -- the LCD might actually be too bright for you!

    Also, the geometry of the screen may be an issue too. I remember when the first generation of "flat" CRT televisions came out, people used to curved monitors thought that the image looked inwardly curved...

    You may not have much of a choice -- CRT's are getting much more difficult to source these days, and when your current one dies, you may not even be able to buy a CRT that suits you!

  5. Use the best LCD panel you can afford on DIY Projector Plans Released · · Score: 1

    For truly enjoying projected images, you will want really solid blacks in addition to the brightest whites - the contrast ratio of the panel will determine how "washed out" the image will look.

    This is why most portable projectors these days use DLP/DMD "light mirrors" - because they can generate true black, and the DMD "light valves" can handle more heat than small LCD's that would otherwise be used in a portable projector.

    The other thing to keep in mind is that cheaper LCD's have a slow pixel response time -- for really enjoyable high-motion video, you'll want a fast response time - a single frame at 75Hz refresh is about 13ms, so if you get a cheap 25ms response LCD, things will looky mushy/ghosty when the images are in motion.

    If you're going through the time and hassle of building one of these, spend the money where it'll make the big difference -- and buy the LCD's with 500:1 or better contrast ratio, and 8ms or better response time.

  10. Get over it! on Universities, the GPL and Patents? · · Score: 1
    You need to relax... Seriously, most of academic work goes out to the world for free. Universities have the clause because once in a bleu moon, a really good patent will turn out to be a money maker for the school, and they use the money from those patents to further the cause of academia.


    A provision of the recent Bayh-Dole Act decrees that universities who retain royalties from licensing of a patent share a fraction of the royalties as personal income to the inventors. By law the university's share of the royalties must be used to further its research and educational activities. In actuality very few patents generate significant royalty income for the university. Notable exceptions include the Cohen-Boyer gene-splicing patent from Stanford University and the University of California, and the fax patent owned by Iowa State.

  11. Budgetary nightmares on What You Should Know When Taking a University Job? · · Score: 3, Insightful

    One problem that I had working at the university was that the faculty's budgets came from various sources with strings attaches, creating a nightmare for IT projects because each professor spent directly on their IT needs, and never on the overall IT "framework" -- worse, since each paid for the service "directly", they expected the service to be tailored to them.

    Imagine having 10 different networks, each with its own server and a different way of running backups, and having no way to share resources because they won't let you!

    Argh.

  12. If you're going through the effort... on Has Anyone Made an Artificial Diamond Ring? · · Score: 1

    ...make sure you spend time on learning about the traditional 4C's of diamond quality: cut, clarity, color, and carat. (5C's if you add "Cost". Heh.)

    The main point of a gem is to be bright (brilliance) and sparkly (fire)... And to achieve that, you want to maximize the light "gathering" tendencies of the gem.

    Clarity, color and carat are fairly well explained, but it seems cut is not always correctly understood. "Cut" does not mean "shape". Instead, it is the quality of how the diamond was cut -- the sub-qualities to cut include its symmetry and polish, and its geometry.

    Personally, a well cut stone can be more sparkly and brilliant than a much larger poorly cut stone, even if the color/clarity of the two stones are similar. In fact, the better cut stone can be more brilliant and appear whiter, even if it is slightly inferior in color.

    There's much talk about "hearts and arrows" among the diamond connoiseurs. What it basically boils down to is that H&A diamonds are proportioned such that they maximize light reflections through much more precise alignment of the light paths (by more careful arrangement of the facets).

    It's the opposite problem of adding "noise" into ray-traced images that look too perfect... The H&A polishers work harder to take away the "noise"... You're trying to minimize light loss through alignment errors!

    Of course, at the end of the day, you just have to look at enough stones to start telling them apart. If you want to escape cheap, go with "ignorance is bliss"... More you study, the more expensive it gets... I ended up spending a month of research to learn about diamonds, and it was quite fun, but ultimately very expensive. (And people do think it's a bit odd when you use a toilet paper roll to study a diamond... But it works!)

  15. Verizon LG VX6000, USB Cable, and Software = 140K on Cell Phone Service as High Speed Internet Link? · · Score: 4, Informative

    For about $20, I was able to get a USB Cable for my LG VX6000 which I use on Verizon. With that, I can get about 140Kbps on the 1x network. I just pay my regular flat rate and my extra $5/month (iirc) for the "unlimited web".

    Being in the boonies, you might not be able to get the 1x network service. On the LG VX6000, you can tell by looking for the "1x" service icon that apperas whenever the 1x service is available.

    The drawback to this, of course, is that your phone is your "modem", and must be connected to your computer during the Internet session; and you will not receive phone calls during your Internet session. So it's okay for periodic use, but may not be suitable for an always-on Internet.

    In my uses, I was able to use SSH, SMTP, POP, HTTP/HTTPS, and AIM. So for my needs, it was effectively unfiltered. One thing that was annoying was the auto-idle-hangup that would kick in from time to time.

    Also, for web-surfing, there is an accelerator software that you can run that would compress images at a (user selectable) higher compression to speed download times of web pages.

    That said, are you sure you are so far off in the boonies that you can't find a wireless ISP? A good WiFi transceiver with the right antenna could easily give you 1 or 2 Mbps over many many miles...

    chatting among sanchalaks is on the rise. Village children use the eChoupal computers for schoolwork,
    games, and to access their academic test results.

    True. But there is one advantage to plug-in cars -- as power plant efficiency at electric generators go up, the existing fleet of cars already on the road will all benefit from that improvement. Non plug-in cars, OTOH, is locked into the design's efficiency at the time or production.

    The other beauty of electric propulsion is that for stop-and-go traffic in the city, the motor draws power only when it's in use. There's no idling at the stop light...

  21. VSLAM on High Accuracy Indoor Location Tracking? · · Score: 1
    BTW, it's interesting to note that the VSLAM allows the robot to be "kidnapped" and dropped off at a new location...

    If the robot is kidnapped at the beginning of exploration (right after the initial map is created), can it figure out its location? Or does the robot start exploration again?

    The vSLAM algorithm contains a novel approach for data processing which enables quick detection and recovery from kidnapping scenarios. Though it's not advisable to kidnap the robot immediately before the landmark database is dense, the robot typically still recovers nicely. However, the recovery from an early kidnapping may be somewhat more time consuming than the recovery from kidnapping when the landmark map is dense and stabilized. Note that the robot does not restart the map building from scratch when it has been kidnapped.

    Evolution Robotic's VSLAM lets robots use odometry AND visual data to update its position information.

    Depending on the size of the warehouse and the manner of "occlusion" that occurs, I'd say wiring up the warehouse with lots of cameras and triangulating to a beacon would be a pretty straightforward method... The hockey puck, indeed!

    This is a great discovery.

    I hope they can realize the goal of being able to read (and maybe eventually send feedback signal back to) the brain to give disabled people highly functional prosthetics.

    But I also think this discovery has great uses for human augmentation. Just like people with six fingers (hexadactyly) can use all six fingers, I would imagine that with sufficient training (plus tuning of the control system), a person can "grow" extra arms. (Think Dr. Octavius in Spiderman 2...)

    But I think the best application for this would be the ability to operate a "keyboard" and "mouse" without actual physical movement. I bet I could think and type about 5 times faster than I do now, if only my fingers had the necessary agility and endurance.
