  1. Re:light travels .3mm in a picosecond on Contemplating Financial Trading At Picosecond Resolution · · Score: 1

    At 10 Gbps. each bit is 100 picoseconds apart. A single minimum sized Ethernet frame is 72 bits so there's 7,200 picoseconds just to get the smallest IPv4 frame possible onto a wire. At the speed of light in a vacuum (things travel slower on a wire or fiber) the first bit will have traveled less than 2.2 meters when the last bit gets sent. Speaking of computer trading in terms of picoseconds is nonsense. IMNSHO

  2. Psyops on Beijing To Track Citizen's Cell Phones · · Score: 0

    It is not that the Chinese gov't is going to start doing anything new. When you use fear as a great motivator to control your people, it never hurts to draw attention to the amount of scrutiny maintained over each citizen (in the interest of the common good). It's best not to let citizens forget for one moment that their actions are subject to significant, continuous observation. [XXX is watching you, from a distance.]

  4. Re:First troll! on Making Data Centers More People-Friendly · · Score: 0

    1... If a part has a maximum temperature of 150 degrees, and runs happily at 120 degrees, the hot isle should be 120 degrees. This way the cooling efficiency is the highest.

    If the component is at the same temperature as the cooling air, then NO energy (heat) is being transferred from the component to the air. There must be a temperature difference (gradient) for heat to flow. Additionally, just because a part may operate at 150 F, does not mean it will live long at that temperature. The life span of must things electronic gets exponentially shorter with increase in temperature. This is why most data centers are kept so cool.

  5. Re:RF interference on Asus Motherboard Box Doubles As PC Case · · Score: 0

    Modern motherboards release a TON of RF energy, and not just from the digital 'clocked' circuitry. Motherboards have on-board switching power supplies to run the processor, and these produce harmonically rich hash also. As, posted earlier, there is no way a cardboard box without a metallic liner could pass regulatory standards for emission and interference to nearby equipment, not in a commercial setting, even more so in the more strict residential setting.

    Chicken wire would not provide adequate shielding of the high frequency energy, either. For one thing, the size of the openings is too large. I can't believe this is a serious idea without at least a continuous foil liner in place, inside the box.

  6. Re:Now let the CIA, NSA, FBI and local cops have i on New Optical Fiber Replaces Glass With Semiconductive Core · · Score: 1

    Yeah, good idea. I'm pretty sure I read something about the need for this technology in an HBGary email or two...

    ... and done without any fancy fiber optic cables?

  8. Books Read? on Ebooks Finally Included On the NYT BestSeller List · · Score: 5, Insightful

    'To give the fullest and most accurate possible snapshot of what books are being read at a given moment you have to include as many different formats as possible,'

    Methinks included also should be books being read without being 'sold', if the aim is indeed to reflect 'books read', and not 'books sold'.

  9. Re:Is anybody really surprised? on Science Programs Hit Hard By Proposed Budget · · Score: 1

    Only two problems with that...

    1) It requires the insight to sacrifice short term (election talking points) goals, for real long term gains.

    2) It makes sense.
