  1. Where is this going? on UK Researches Future 10Gbps Broadband Technology · · Score: 4, Insightful

    Again, the meme is presented that ultra-fast broadband leads to competitive advantage.

    Is this a genuine proposition? Can it lend competitive advantage to one power bloc over another on a global scale? Probably not. Everyone is as smart as everyone else and the technology platform is relatively "flat". Throughout history, we have noticed that when something is discovered, it is often discovered almost simultaneously in multiple centres. If competitive advantage lasts only a short time, what kind of "advantage" is it?

    8Gbps is required for VLBI (Very Long Baseline Interferometry). Multiples of 10Gbps trunks are required for large Internet exchanges, datacentres etc. What is the killer application that mandates 10Gbps on a wide scale? Even 1080p video is only around 3Gbps. Are we suddenly talking about multiple HD streams batting their way around teh interwebs to consumers?

    We are starting to move into uncharted territory by discussing these kinds of capacity at the network edge. Small amounts of megabits are relatively easy to handle at the consumer level. Drop a 1Gbps trunk on the floor and you have a major problem. Putting 10Gbps to the edge makes the network more "nervous" and much harder to maintain and control.

    While full service delivery over Active Ethernet has scaled up incredibly well to the point where it is now accepted at corporate mission-critical level, do we have the necessary capability to design, deploy and maintain networks at the proposed capacities?

    At a technical level, Bandwidth Delay Product will kill your throughput over anything but short distances. You probably reach a point of diminishing returns where 10Gbps is enough for metro and national connections, but beyond that it is trunked and we know how to do that.

    So if it isn't competitive advantage and it isn't enabling consumer-level killer applications, then what is it? Are we getting to the point where we need to start thinking about massive high-speed interconnectivity in a totally new way? That it isn't just to enable commerce or competition or local or global advantage, but that it in fact is something much more valuable? Global self-awareness, anyone?

  2. Re:Sleeping after kids on The Dangers of Being Really, Really Tired · · Score: 1

    Ah, THOSE sleep problems are long gone, yes. The 6-month old sleeps all night and so does the 3-year old. I got the bedtime routine sorted fairly early. My only issue now is that he is full-on from 5:22am until 7:30pm. All day, every day, no exeptions for daylight savings. Lots of fresh air and exercise helps, and rock-solid routine at bedtime.

    Explaining space to a 3-year old? I don't know. He seems to explain it to himself as we go along. Here we are blessed with clear skies and not much light pollution, so a lot of stuff is obviously visible. He knows the difference between stars, moons, suns and planets. We are just back from the local observatory where they have an indoor 30cm telescope and two outdoor 50cm ones. So after tonight, he knows about galaxies and globular clusters as well.

  3. Re:Sleep deprivation is very serious on The Dangers of Being Really, Really Tired · · Score: 3, Interesting

    I have done multiple instances of 7 days without sleep over the years - that's about my limit. Currently I have a regime of around 5 hours per night (over the last 10 years).. At Uni I regularly used to work 9am - 6pm, break, then 11pm to 6am, then break, for months at a time.

    My point is that nothing, NOTHING, prepares you for the level of sleep deprivation that you suffer when you have kids. Strategies for dealing with a 3-year old who is heavily into animals, space and big machines, anyone?

  5. Work it backwards on Surveying the World of the Biggest Server Farms · · Score: 1

    What are the current server specifications necessary to support 50K virtual instances of an O/S? How many boxes does that need to map down to in order to maintain sufficient redundancy and power efficiency? Now, how big a datacentre do you need to support that number of servers and hence what space/power/air conditioning requirements would you actually need?

    Google's container-based datacentre is about 1300 servers. If each of those is capable of running multiple instances, that would bump up the total.

  7. Re:If you're dealing with phone numbers on New Pattern Found In Prime Numbers · · Score: 1

    Another reason that 999 was selected for the British emergency number was because all rotary dial phones in the UK had a metal bar at the last digit. Therefore, in the dark or blinded, you could find the bar, move your finger to the left and you would know that you had the 9.

    Also, any analogue line in the UK should be able to make emergency calls, regardless if the line is active (i.e. tied to an account). This is supposedly the case in New Zealand and Australia as well

    Of course, if your particular emergency involved the loss of fingers, you were pretty much screwed with rotary dial phones

  8. Empirical Test on MPAA Says Teachers Should Camcord For Fair Use · · Score: 1, Insightful

    Experiment: Take a random sample of teachers. Equip half with camcorders, a DVD, DVD player and TV. (For completeness, include a group that can take a feed from the DVD player directly to the camcorder). Equip the other half with a PC, DVD ripping software, a DVD and DVD player.

    Measure the time taken to extract a clip from the specific DVD and the quality achieved by each group. Compare results.

    Hypothesis: Quality obtained by first group will be acceptable and is a lower-tech solution than that needed by second group

  9. Re:Its noteworthy ... on Google Urges National Inventory of Radio Spectrum · · Score: 2, Interesting

    And stops at 3.5GHz, bizarrely, while there is still a lot of very useful spectrum above and beyond that, including the ISM and UNII bands at 5GHz. No point in going as far as 60GHz, since that is next to useless, apparently.

  10. Re:60GHz is available because its almost useless on 60GHz Uber-WiFi Proposed By New WiGig Group · · Score: 0, Flamebait

    Sure. Step 6 is where you went wrong. And your conclusion at step 22 is incorrect. And if you continue to work in areas where you aren't certified, you will continue to be wrong. No charge for the diagnosis.

  11. Re:60GHz is available because its almost useless on 60GHz Uber-WiFi Proposed By New WiGig Group · · Score: 2, Informative

    "Competence" = "practised by a certified engineer". We did extensive testing before lighting the link up. We even threw a faulty unit back at Bridgewave due to a fault in a $1.70 part (in a $40K unit) that our testing picked up. (Hey, we still managed to line it up when the voltmeter was reading 0.3V instead of 3.3V) The point is that you probably had a duff unit, but also that engineering is more than just point and click - it also involves selecting, testing and verifying that your equipment is doing sane things. It doesn't imply that 60GHz is somehow unusable as a data transmission frequency. Quite the contrary, as others have pointed out.

  12. Re:60GHz is available because its almost useless on 60GHz Uber-WiFi Proposed By New WiGig Group · · Score: 2, Funny

    You must be incompetent. I have a 60GHz Bridgewave unit working in my network with 100% uptime over 18 months at 100Mbps. Alignment is not easy - you are trying to get two 1 degree beamwidths lined up, so you do need to know what you are doing. In my case, the alignment is over 800m, it took 30 minutes to dial it in and once locked down, performance is flawless. Don't try operating one of these in a high rainfall environment though, the absorption will kill performance over anything but very short range.

    In addition, as we have reported earlier, the broadcasters also want to delay the currently-scheduled November 4 vote in order to allow more time for comments on the FCC's engineering study.
