  1. They don't keep the electronics? on U.S. Confiscating Data at the Border · · Score: 0, Offtopic

    So, you illegally try to enter the country and we give you back all your stuff? Maybe it would be a dis-incentive if the computers and iPods were kept rather than just copied. And I'm only half-kidding.

  2. Beware - only Cat 5 on 1.4mm Thick Gigabit Ethernet Cable · · Score: 2, Insightful

    I'm in the category cable industry and would be weary of using this cable for Gigabit Ethernet. The release only mentions that the cable is rated at Cat 5 (Not Cat 5e) which means it is only good for speeds up to 100 Mb/s. You need a true (verified) Cat 5e cable to run 1000 Mb/s (Gigabit) ethernet.

    That said, this would be find for most home networks.

  3. Re:I say go for it! on Gigabit Networking for the Home? · · Score: 1

    Actually, Gigabit requires Cat5e as it uses all 4 pairs. While Cat5 may work (as it is usually run on the same machines as the Cat5e cable), Cat5e is technically required. Cat5 is only tested for ACR (Attenuation to Crosstalk Ratio) which is basically Signal to Noise Ratio two pairs at a time. Cat5e is tested for PSACR (Power Sum Attenuation to Crosstalk Ratio) which is basically Signal to Noise Ratio all pairs considered. Also, if you hook up Cat5 it will "work" but you may not notice all the dropped packets and re-sends required on the network which will really slow it down. Finally, homes may be better off due to their shorter runs of cable which generally help out the PSACR numbers - so that may be another reason why Cat5 may "work" in the home for Gigabit, although not technically designed for that use.
