Cheap Wireless for Accessories

morcheeba writes "Yet another wireless protocol for personal computers! In addition to existing 802.11 variants, bluetooth, and ultra-low-power newcomer zigbee, Cypress semiconductor is releasing a simple low latency, low cost (<$2), medium speed (200kbit/sec) protocol with USB human interface devices (HID) compatibility. Partners include Saitek (game controllers) and NMB (keyboards & mice). EETimes has an informative article."

  1. But... They use IPV6! :-( by Michael's+a+Jerk! · · Score: -1, Offtopic

    While IPv6 fixes many problems in IPv4, the developed world will not
    embrace IPv6 until many shortcomings in the protocol are addressed.

    1. Cisco routers suck at IPv6. Many of cisco's routers use the
    router's CPU to process IPv6 packets instead of the fast-path. The
    reasons for this are explained in the next few points. While Juniper's
    routers are substantially better at IPv6 than cisco's, IT managers are
    often restrained by insane corporate policy that dictactes the use of
    cisco.

    2. There are too many addresses. There are 16.7 million addresses per
    square metre of the earth's surface, including the oceans. This is
    overkill. The world does not need more than the 4 billion addresses
    available with IPv4, and I challenge you to come up with an
    application that requires that many. Assuming that you can actually
    come up with one, it could easily be solved with Network Address
    Translation, or NAT as it is commonly known.

    3. IPv6 addresses are too large. An IPv6 address is 128 bits in size -
    64 bits of which are reserved for addressing hosts, and 64 bits of
    which are reserved for routing. One thing that is cool with IPv6 is
    address autoconfiguration. Take your 56-bit MAC address on your
    ethernet card, ask for 64-bits of network prefix, bang it together
    with EUI-64 and you are set. The problem with a 64-bit network prefix
    is that routing tables become massive. Just do the math and you'll see
    that extreme amounts of memory are required to hold routing tables.

    4. The IPv6 header is too large. An IPv4 header compact at 20 bytes in
    length, while the IPv6 is bloated at 40 bytes. That's right people,
    each one of your IP packets has twice as much overhead as before.
    While this may not sound much, IP networks have a requirement that the
    minimum MTU supported must be 576 bytes. That means that where you
    might have got 556 bytes of data in your IP packets, you now get 536
    bytes. This means that downloading stuff will take 3.4% longer.

    Sure, IPv6 allows for nice hacks like those described in this article,
    but is it really ready for prime time?

      Great! Thanks.

      I still don't get why in every fucking porn movie the guy has to blow his load on the girls face. I mean when I'm watching porn, I don't want to see some guy cumming all over the place.

  4. Sad News... Filthy Critic dead at 54 by Anonymous Coward · · Score: -1, Offtopic

    I just heard some sad news on talk radio - movie review writer The Filthy Critic was found dead outside the Arvada Tavern last Thursday. He died the way he lived--wobbling aimlessly in the slow lane. I'm sure everyone in the Slashdot community will miss him - even if you didn't enjoy his work, there's no denying his contributions to popular culture. Truly an American icon.

      He didn't.

      It was a hoax. The fucked up jerk staged a suicide on his webcam.

    just keep yOUR little heads in the sillysand, & your cc #'s at the ready. how cute/disgusting.

    even when we cheered for/agreed to send money to the hobbyists,, mynuts won again. sheesh. fauxking greed/fear based corepirate nazi puppets/cowards they are.

    this fauxking avoidance of the planet/population rescue project (previously unknown as the oil for babies program), & failing to fess up on the stock markup swindles, is disheartening, to say the leased, y'all sure spouted off A LOT before you became won of those phonIE Godless payper liesense stock markup billyonerrors. same with va lairIE, & his whoreabull patentdead PostBlock(tm)/SourceForgerIE kode stealing/censoring devices. that's ok dough, as it's not yOUR worst problem.

    no matter. back on task.

    as to the free unlimited energy plan, as the lights come up, more&more folks will stop being misled into sucking up more&more of the infant killing barrolls of crudeness, & learn that it's more than ok to use newclear power generated by natural (hydro, solar, etc...). of course more information about not wasting anything/behaving less frivolously is bound to show up, here&there.

    cyphering how many babies it costs for a barroll of crudeness, we've decided to cut back, a lot, on wasteful things like giving monIE to felons, to help them destroy the planet/population.

    no matter. the #1 task is planet/population rescue. the lights are coming up. we're in crisis mode. you can help.

    the unlimited power (such as has never been seen before) is freely available to all, with the possible exception of the aforementioned walking dead.

    consult with/trust in yOUR creator. more breathing. vote with yOUR wallet. seek others of non-aggressive intentions/behaviours. that's the spirit, moving you.

    pay no heed/monIE to the greed/fear based walking dead.

    each harmed innocent carries with it a bad toll. it will be repaid by you/us. the Godless felons will not be available to make reparations.

    pay attention. that's definitely affordable, plus you might develop skills which could prevent you from being misled any further by phonIE ?pr? ?firm? generated misinformation.

    good work so far. there's still much to be done. see you there. tell 'em robbIE.

    the rest of the wwworld is laughing/crying at/for US in sympathy/disgust, as we fall/jump into the daze of the georgewellian corepirate nazi life0cide, whilst criticizing their ip gangsters, which are also members of the walking dead.

    you, as fuddles does, seem to have an ability to pretend that there isn't anything happening outside of your phonIE boundarIEs. treating the public as if they do not exist. that's ok, for now.

    we think it's some kind of corepirate nazi ?pr? puppet training. it's not hard to spot, by anybody. because most folks have nothing to say, does not mean that they are not paying attention (previously descibed).

    the result is: as everywon sees your .asp falling off, you must pretend that you remain in charge of something. a lot of phonIE machinations to end up as a pawn/dupe for the walking dead. y'all do this for monIE? that's scarIE. lookout bullow. run for your options, should you have any left.
