    LaTeX, VIM, IceWM, gnuplot, xfig, Octave, Firefox. Done.

  2. MS Search? on Is Microsoft Crawling Google? · · Score: 1

    I'm sceptical of the MS search. Try a search for x-windows...

  3. Re:LOS issues, WISP on Motorola Field Tests Wireless Broadband At 300Mbps · · Score: 1
    I'm going to assume that 300 Mbps is LoS between the units?

    That is what makes OFDM neat. It works well in multipath environments. LOS isn't a requirement.

  4. Re:Many things to consider... on Motorola Field Tests Wireless Broadband At 300Mbps · · Score: 1
    Plus, cell phones have such limited battery use times, that I doubt anyone would really use those other features for more than a very limited time.

    Right. In addition, OFDM is well known to have a large peak-to-average power ratio. This means it is very difficult to amplify the signal efficiently. The power efficiency of OFDM is very bad and this is one of the current hurdles to get OFDM into mobile battery powered devices.

    I will believe it when I see it. OFDM technologies can make many claims about data rates and bandwidth efficiency but if your battery only last 30 seconds, that 300 Mbps data rate doesn't do much for you!

  5. Re:How long until WiLan sues 'em? on Motorola Field Tests Wireless Broadband At 300Mbps · · Score: 1

    R. W. Chang from Bell Labs patented OFDM back in the 60's. I don't know the current state of the general patent.

    Dude, 1 hour of yoga a day keeps the belly away. Seriously!
