    A simple addition makes the TI-99/4A version look visually just like the C64's. That is to simply define the forward and backward slash characters to look more the C64's and span the whole area of the character's bitmap.


    10 CALL CHAR(47, "C0E070381C0E0703")
    20 CALL CHAR(92, "03070E1C3870E0C0")
    30 PRINT CHR$(INT(RND+.5)*45+47);
    40 GOTO 30

    Finally, if we're going to go to the trouble of defining character images, then we might as well use contiguous character codes so we don't need the extra math. We could use the C64's exact values, however the TI's character set only has 128 characters. So we'll use values 100 less than the C64 version. Also, the TI rounds floating values to integers, whereas the C64 simply truncates them. So we don't need to add .5 to the random value.


    10 CALL CHAR(105, "C0E070381C0E0703")
    20 CALL CHAR(106, "03070E1C3870E0C0")
    30 PRINT CHR$(105+RND);
    40 GOTO 30

    That's be cause you don't appreciate the context in which this code came to exist. Back in the early eighties, to be able to generate such visually impressive and complex looking imagery with so little code, was quite an amazing thing. I, for one, wish I would have known that bit of code back then as a ten year old. It certainly would have beaten my usual "10 PRINT "DAN WAS HERE!!! "; 20 GOTO 10" that I would type into the C64s, TI-99/4As, Atari 800s, and other computers on display at K-Mart and Sears.

    For the sake of completeness, here is a version that works with the syntax (and character set) of another home computer of the era, the TI-99/4A


    10 PRINT CHR$(INT(RND+.5)*45+47);
    20 GOTO 10

    The code is a little more complex because the forward and backward slash characters are not contiguous in the TI's character set (47 and 92). The result visually isn't as good because the TI's character glyphs are more spaced out than the C64's. However it does work - I tested it in the emulator (with standard TI BASIC, doesn't required Extended BASIC).

    According the the video, they're using a Kinect for 3D tracking of the ball. That's pretty good resolution to result in high enough mechanical precision to make a catch. Also would reduce the cost of this project by a small fortune.

    However, the article differs from the video. The article says "A Kalman filter algorithm is used to analyze video captured on an external camera system consisting of a Kinect-like ASUS Xtion PRO LIVE to track a colored ball in three-dimensional space and predict its destination and timing."

  12. Compete directly! on Ask Slashdot: How To Make a DVD-Rental Store More Relevant? · · Score: 1

    Take on your biggest competition - Netflix and Redbox - head on. This will only take "homework", which is just the owner dedicating a little time. Create a special, prominent movie section. Start picking out very popular yet older movies. Check if each of those movies are available locally at Redbox, Blockbuster kiosks, and / or streaming (Netflix, Amazon, etc). That can be done totally online. Any of those movies that you have for rent that are not available through those other sources go in your new movie section. This section needs to be promoted as movies you can get NOW, that you cannot get ANYWHERE ELSE. "Instant Entertainment", that can only be had from your rental store.

    You do have exclusivity! That is what you need to play on. There are HUGE gaps in what is available for streaming, and Kiosks have such small capacity that pretty much all they carry are the latest releases. All that is required is to recognize which titles meet that marketing criteria, which should be done weekly, and most importantly, to let customers know that your competition actually provides a very small and incomplete selection of movies.

    Take this even further by promoting series and prequels to movies currently in theaters. For example, The Hobbit is coming out next month. Interest in the entire LOTR series will be increased because of it. Same with Twilight. Promote all the previous movies. Most of those are not available via streaming, and would be hit or miss in kiosks.

    In addition, you need to have as large a collection of older movies as possible. Even if they don't fit on normal display shelves, or if you have to pack them in tight like books on a bookshelf, you cannot have too much selection or too many older movies. If you must, store the older ones in a storeroom and provide a listing / directory of those titles people can choose from. Ideally, list the movies on your website so people can at least browse them online. Even you don't have the infrastructure to set up a site allowing people to reserve online, they can still easily call and reserve that way.

    The most important part is bringing specific movies to people's attention. There are many, many older flicks people have completely forgotten about that they would enjoy, and can only get instantly through your business locally. So you need to promote good movies on a regularly changing basis.

    Now, I will point out that Netflix and others do have mail service, where people can "rent" physical movies online. Yes, you can pretty much get every movie ever made that way. However there are two huge downsides:
    1) No a la carte. People have to pay a recurring monthly membership to get those moves, and Netflix has split that service off of its streaming services. The customer can't just pay $2 for a single movie that caught their eye, and that is a big turn-off. That makes your service more economical for people who aren't planning on circulating a dozen different DVDs back and forth to Netflix a month.
    2) It's not instant. A huge appeal of a brick and mortar store is the ability to go in on a Friday night and grab a few movies for the weekend, and that requires instant gratification.

  15. Re:Coded TCP ? on New WiFi Protocol Boosts Congested Wireless Network Throughput By 700% · · Score: 4, Informative

    No, the MIT scheme is a formal protocol which requires both the access point and the client devices to work together. The client is able to "fill in" missing data, because the data itself is expressed in a computational manner that allows the client to perform calculations and solve for missing data.

    What the NC group has done is simply made access points more assertive and "take control" of a channel by ignoring the fact that other devices are transmitting and talking over top of them. That scheme is applied when a backlog of data occurs, and assuming that most clients are consumers of data, it makes sense to push out cached data instead of wasting time listening to clients make additional data requests. Part of the reason this would work is that access points are optimally located in a given coverage area, they use higher gain antennas, and don't worry about reducing power to conserve batteries and the like, which allows them to "talk over" your typical client data consuming device.

  16. Data consumers on New WiFi Protocol Boosts Congested Wireless Network Throughput By 700% · · Score: 5, Informative

    Sounds like this is based on the simple fact that most internet clients are consumers of data, not producers (high download to upload ratio). So if you make the access point more bossy, to the point of no longer playing nice and waiting its turn to transmit (thus it will be transmitting over the other devices in this mode), the overall result is more efficiency when moving larger amounts of data.

    This makes sense on a number of levels. There is no point in letting client devices waste airtime requesting more data (again, assuming they are primarily consumers of data) when there is already a backlog of data that needs to be pushed down the pipe. Additionally, access points are centrally located and have higher gain antennas, thus even when they "double" with another device, there is a good chance that the recipient device will still be able to "hear" the access point over the other devices.

    So I can see how this "high priority mode" would work, even if the formal protocol doesn't support it (ie the client devices can be totally stock). It's like being in a room full of people talking, and instead of waiting for people to quiet down to tell a friend across the room something, you simply start yelling. They are able to hear you because you're louder (higher gain antenna), and the other people don't have to quiet down either (since they're just talking).

    There would likely be problems with this scheme when multiple access points have overlapping coverage - there would be lots of collisions at the fringe areas where they overlap. It would also have problems when someone is performing a large upload at the same time someone is streaming data down, because the access point would keep turning a deaf ear to the uploader. Also, if you had two clients sitting side by side, then that extremely close proximity could result in too strong of a client / client signal that the access point couldn't overcome.

    I've been rather surprised at the porousness of Apple's walled garden. My iPad is 100% stock (not jailbroken, etc), and all of the apps came directly from the app store. A couple weeks ago I noticed some odd files in my dropbox root folder. There were two executables - one for Windows (Xbox 360 MSP Generator.exe.), one for OSX (IGenerate 6.7) - both for generating "free" XBox points. Fortunately Dropbox allows you to (via their web interface only) view the versions and history of files. Both those files came from my iPad. Then last week it happened again with just a windows executable (iLividSetup.exe), also from my iPad.

    So some iOS app is interacting with the Dropbox app in some way (either via API or just throwing files into a folder that Dropbox must have all permissions open on). I have yet to determine which app it is. I only use 6 or 7 apps regularly, so I'm pretty sure it's not any of those, and I have yet to do a more systematic check on the other dozens of odd lesser used apps. The moral of the story is that these app stores are not foolproof by any means, and malware is still being approved, even if the attack vector is novel, dependent on a 3rd party app (dropbox) and is cross-platform.

    Anyone else see this behavior in their Dropbox files?
