  1. Re:Easy enough to avoid on New Software For Employers To Monitor Facebook · · Score: 1

    So if anyone is interested, a friend of mine has been working on this site for some time (http://www.spokeo.com).

    It appears to crawl public registries, facebook, myspace, etc to formulate an identity based on relations, former addresses, phone numbers, etc ... regardless of their email address. However, e-mail does appear to trigger the highest bang for the buck. Although I won't comment on the Pros/Cons - all those naysayers really need to do their homework first. Market Research / Online Data-Mining is clearly VERY sophisticated.

  2. Berkeley Admins have questionable methods. on What's Banned On Your Campus? · · Score: 1
    In a letter to a student, University of California, Berkeley officials said this:


    Dear ,

    I wrote to you two weeks ago regarding slow network connections in the
    Residence Halls. I am writing you today with an update. At present,
    residence halls have high speed connections (100Mbs) to each other and to
    all resources located on campus. Transfer rates to servers outside of
    campus, however, may continue to be slow at times.

    The amount of traffic from the residence halls to the outside world has
    increased dramatically over the past few months. Residents who are using
    large amounts of bandwidth to the outside world, by running the popular
    software Napster or popular FTP and web servers, are greatly diminishing
    network transfer rates for everyone else with a residence hall connection.

    The residence halls share bandwidth with all other campus users, including
    ongoing research projects which rely on consistent connection rates. To
    ensure adequate bandwidth availability for all campus uses, the department
    of Communication and Network Services has restricted the total amount of
    bandwidth available to the residence halls for communication with the
    outside world. The e-mail below from the Director of Communication and
    Network Services provides details on the actions they have taken.

    Residential Computing is continuing to work with Communication and Network
    Services to achieve a balance between competing demands for bandwidth
    throughout campus. We understand that current transfer rates from sites
    beyond campus are slower than they have been in the past. If you are
    currently using Napster or running a web server, we strongly encourage you
    to stop. If you have a friends who are running Napster, we encourage you
    to ask them to stop. Through increased resident education and ongoing
    discussions with Communcation and Network Services, I will do my best to
    improve network connectivity for all reshall students.

    Please read the message from Communication and Network Services below for
    more information.

    >From Cliff Frost, Director of Communication and Network Services regarding
    network connections in the residence halls:

    Background:

    The Berkeley campus pays approximately $600 per megabit/second/month for
    connectivity to the worldwide Internet. (There are start-up costs not
    included in that figure, and a base cost below which the total cost cannot
    go, but that is a good approximation of our current cost.)

    The Residence Hall networks are very well-connected to the rest of campus,
    and to the Internet in general. This is accomplished via a 100
    megabit/second connection between the residence halls and the rest of the
    campus network.

    Up until approximately November, 1999, the sustained use of the
    Residence Hall network connection was approximately 15 megabits/second.
    This was for all traffic--both with other campus sites and with the
    Internet in general.

    Recent History:

    Coinciding with the tremendous popularity of "napster" (which is a very
    nice tool in many ways) there has been a tremendous and rapid growth in
    the campus's traffic to and from the Internet. This growth also
    coincided with a similar growth to and from the Residence Halls.

    In looking at the traffic patterns, and concerned about how we would
    pay for the exploding use of the Internet, CNS staff noticed that traffic
    across the 100 megabit/second connection to the Residence Halls had sprung
    up to peaks of 40 megabits/second and a sustained level of 25. At that
    point, CNS put a cap onto the traffic that the Residence Halls could
    exchange with off-campus sites, at 20 megabits per second. Note that this
    cap did NOT apply to traffic with other on-campus sites.

    The effect of the 20 megabit/second cap was immediate. Traffic across
    the link dropped to peaks of 22-25 megabits/second, implying that most of
    the traffic across the link is with off-campus sites.

    CNS later set the cap at 15 megabits/second and then to 10. From the
    data gathered it appears that the Residence Halls exchange between 2 and 5
    megabits/second with the rest of campus. All the rest of the traffic is
    bound for the Internet.

    Current Status:

    At the request of Housing & Dining Services, CNS has temporarily raised
    the cap to 15 megabits/second while we try to work out ways to manage
    the explosive demand for Internet bandwidth from the Residence Halls.
    Housing & Dining has asked for CNS's assistance in analyzing the situation
    and developing potential solutions.


    I don't think this was the particularly BEST way to get around Napster. Actually, I find this method grossly useless. Exactly HOW does this work to effectively distribute the load? The cap of the internet connection went on throughout finals over a period of 2-4 months.



    I forget that Berkeley has an extreme dedication to their grad students by which all other students come second. This happened to be another fine example where by cutting of all the undergrads, they'd preserve the connection for the research labs.



    From the numbers alone, I'd think that cost was as well a very large factor. *sigh* The latest cap was probably to average out the the active months and thus fix the budget. I can't help but feel a bit cheated for those students. If this is the method of our more prestigious schools, what will happen to the rest?
