  1. Re:TI Basic on Scripting In Commodore BASIC For Windows & Linux · · Score: 1
    Greetings,

    I recall playing a version of the "Asylum" adventure game on a TRS-80 Model III compatible computer, with its blocky graphics. I was very amused when I discovered the piano-falling-on-head quirk.

    I never got past the part in the labyrinth with the mirror, apparently only the second phase of the game (a friend later told me how, but by then I did not have that computer anymore).

    A Google search turned up references to the C64 version of the game, which apparently had a version with superior graphics, e.g., [1] and [2].

    Greetings,
    I sort of recall discussions on using an active sensor network for sniper location. Here's a Google results page for "sniper sensor network location":

    The original DARPA-DOD call for proposals in consideration, DARPA BAA-99-21 Self-Healing Minefield (SHM), specified *anti-tank* mines, NOT anti-personel mines.

    REF: Electronic Voting - Brazil

    Greetings,

    I have used the system several times in the past years.

    Really straightforward: walk in (or wait in line), identity verification, sign receipt, walk to booth, terminal is authorized (using a remote wired keypad) by the election officer, type in candidate number (I believe one can scroll to the desired candidate, when the list is short), candidate info appears (photo [1], name, nickname, number, party), confirm, confirm again, in case of multiple elections (governor, senator), repeat process, walk out of booth, pick up receipt, walk home [2].

    I'll post some links when I find the time (they'll probably be in portuguese, though). Here's one off a senator's website, addressing possible security issues (it's a bit dated, pre-2002 elections).

    ---
    [1] this applies to the recent presidential elections, I don't recall if the photo appears when voting for town council representatives and other positions with a large number of candidates.

    [2] I live near my voting zone office, about 6 blocks away. And, voting days are national holidays (mandatory voting), so traffic is usually light.

  5. "new" Linux-based PDA alternative: Motorola A760 on Sharp Ships Zaurus SL-5600; 5500 Available Cheap · · Score: 2, Informative
    Greetings,

    There is another contender in the Linux-based PDA arena: the Motorola A760.

    It is also a GSM dual-band cellphone, supposedly coming out in late 2003.

    I believe I read something on slashdot.org about it earlier, but can't find the URL. Here are other URLs with text on the device:

  7. public wireless data networks in Brasil on Flat-Rate Wireless Where The Sun Don't Shine (Much) · · Score: 1

    I would bet that a neighbourhood network would be the fastest way to get wireless access on the go here in Brasil, given the penchant for community efforts here (e.g., community "radios" comprised o a network of loudspeakers, and mass construction efforts, known as "mutirões", where the material is supplied by local government and the labour by the beneficiaries). Since daily access to private computers is limited to the higher middle class and above, I believe that a possible implementation woudl perhaps spread out from university areas (given their higher bandwidth links), although there would probably be legal and regulatory restrictions to that (as well as security issues).

    Just my 2 bits (well, a bit more (several) than that).

    BTW, I would be interested in more material pertaining to the wireless experiment mentioned in the originating email. Thanks.

    REF: Trademarks becoming synonymous with the product (usually due to effective marketing or widespread use)
    Location: Brasil

    Greetings,

    As a related aside, I would like to mention that in Brasil, the Xerox trademark has become synonymous with photocopying, both noun and verb (xerox, xerocar). Other instances include Gillette (razor) and, to some extent, Bic (common ballpoint pen).

    I believe that there is a small advantage to "being incorporated into the cultural landscape": instant (ex)brandname recognition.

  10. Recycling batteries in Albuquerque, Europe, Brasil on IBM Offers Computer Recycling · · Score: 2

    I believe that batteries can be taken back to the stores for recycling in Europe only because the battery companies there are required by law to have a recycling structure in place. Perhaps the recycling of batteries results in less reclaimable material than recycling paper, plastic or aluminum parts.
    I believe that in the USA, that sort of legislation would be seen as restrictive and therefore may be difficult to approve.
    In Brasil, although battery recycling is mostly ignored in most regions (with exceptions mostly in the southern region), I have seen several recycling dumpsters with a specific bin for batteries. I am not sure what they actually do with them after collection. As for recycling other material, that process runs the gamut of modern recycling sites to poor who live off meager earnings from picking through trash landfills. Rather sad.
    I have tried to find places to recycle used batteries in Albuquerque, NM. Unfortunately, the recycling bins found at the Wild Oats grocery stores are only for paper and glass. Radio Shack was of no help.
    I, for one, would be interested in a list of places one could normally take the batteries to be recycled. Anyone?
