Sluggish WiFi Connections Hurt Everyone

MindNumbingOblivion writes "Wireless technology has revolutionized access to local area networks when one can't always be close to an ethernet jack. But a recent research paper from the French Centre Nationale de la Recherche Scientifique tells how one slow user accessing a hot point can hurt the whole group. Apparently the very nature of CSMA/CD guarantees such anomalies. Here's the story, and here's the release from CNRS (in French)."

  9. Easy enough to solve this problem by curtlewis · · Score: 0, Offtopic

    Just install switches instead of hubs. Kiss CSMA/CD collision issues goodbye with a dedicated switch port for every system/device.

    In days past, it was cost prohibitive to do this, but with cheap switches these days, why not? I run a switched net at home, not that I really need to, but if I happen to be doing a 2 gig file copy from one box to another, at least I can surf the net without any slowdowns.

    My Dear,

    After a discreet but thorough investigation
    at the foreign affaires office of the Lome chambers of commerce,I with absolute confidence in the legality of your company and Intergrity of your person essentially,the business I am about to commence with you fundamentally based on trust and sense of purpose.

    Briefly I am Mr. Alfred Dadah director in charge
    of auditing and account section of INTERNATIONAL
    BANK OF AFRICA LOME-TOGO.

    With due respect and regard,I have decided to
    contact you on a business transaction that will be very beneficial to both of us at the end.

    During investigation and auditing in this bank,
    I came across an amount of money belonging to a deceased couple, who died on EgyptAir
    Flight 990 plane crash of 31st october 1999. No body was recovered from the crash site. his is the website. www.cnn.com/us/9911/02/egyptair990.list/index.html
    This fund has been dormant in their account with my Bank without any claim of the fund that is in our custody neither from his family or relation before my discovery to this development.
    Although personally, I kept this information secret to enable the whole plans and idea be profitable successful during the time of execution.

    The said amount was $10 million US dollars(Ten
    million US dollars). Meanwhile all the arrangement to put claim over this fund as the bonafide next of kin to the deceased,To get the required approval and transfer this Money to a foreign account has been put in place by me. Also directives and needed information will be related to you as soon as you indicate your interest and willingness to assist me in this issue.

    In fact I could have done this deal alone, but
    because of my position in this country as a civil
    servant, we are not allowed to operate a foreign
    account and would eventually raise an eye brow on my side during the time of transfer because I work in this bank.

    This is the actual reason why it will require a
    second party and a foriegner who will forward claims as the next of kin with affidavit of trust of oath to the Bank, and also present a foreign account where he will need the money to be re-transferred into on his request as it may be after due verification and clarification by the correspondent branch of the bank where the whole money will be remitted from to your own designated bank account.

    I will not fail to inform you that this transaction is 100% risk free.On smooth conclusion of this transaction, You will be entitled to 25% of the total sum as gratification,while 5% will be set aside to
    take care of expenses that may arise during the time of transfer, while 70% will be for me and my investment purposes which you will also assist me.

    Please, you have been adviced to keep this as top
    secret as I am still in service and intend to
    retire from service, after concluding this deal
    with you.I will be monitoring the whole situation
    here in this bank until you confirm the money in
    your account, and ask me to come down to your
    country for subsequent sharing of the fund according to percentages previously indicated and further investment. All other necessary information will be sent to you when I hear from you.

    I suggest you get back to me as soon as possible,
    Stating your wish in this transaction.

    Yours faithfully,

    Mr Alfred Dadah

  11. But pirated MS Office software is free, too by release7 · · Score: -1, Offtopic
    I don't know one individual who has purchased a copy of Microsoft Office. Sure, businesses will buy it but then workers take that "backup" copy from work and install it on their systems. From there, MS Office is obtained through the friend of a friend of a friend method. And you can bet it's an unstated but integral part of Microsoft's business strategy because it makes their products more universal. Besides, when you've got $40 billion in the bank, it just doesn't matter.

    So, as long as MS has businesses in their back pocket, they've got little need to worry about competing with free, as in freedom, software.
