  1. Re:LOL. on US Internet Offers 10Gbps Fiber In Minneapolis · · Score: 1

    Are they going to drop into every customers home a router capable of 10Gbps of throughput? LOL. That would be expensive.

    Not only the 10GbE switches are expensive ($100-200 per port) but the network cards are too. Making them work in a regular PC is a nightmare, most motherboards bus-fault and bluescreen / kernel panic in minutes.

  2. Re:What's beyond Cat6? on US Internet Offers 10Gbps Fiber In Minneapolis · · Score: 1

    Cat6A - usable for 10GbE up to 100m. Cat 6 works with 10GbE but only for short runs, up to 10-15m.

  3. Re:Not so sure on Deutsche Telecom Upgrades T-Mobile 2G Encryption In US · · Score: 1

    They can use a great encryption algorithm, but if they continue to not authenticate the basestation, as per 2G specs, then it doesn't really help. It wasn't until LTE that this finally started happening.

    This problem can be solved at the Mobile Station or SIM by refusing to register or call over a network that does not support at least UMTS authentication of the network and replay protection or that does not activate encryption. This would break connections to 2G networks whose MSC was not updated to support UMTS authentication but it could be implemented as an user option.

    Judging by how VoLTE got implemented you'll have to wait for iPhone 8 or maybe 9...

  5. Voice and data are separated on US Wireless Carriers Shifting To Voice Over LTE · · Score: 1

    VoLTE IMS voice uses a dedicated low latency guaranteed bearer for the RTP packets. Traffic on this bearer is charged separately and is not routable to regular Internet.
    The SIP signaling also uses a dedicated AP that cannot be used for anything else. Traffic is only allowed towards P-CSCF.
    All the IMS client, Quality of Service and dedicated bearers are implemented in the baseband chip (Qualcom dominates that market) and is off-limits to the operating system of the phone, even to root.

  6. Re:Power? on Navy Debuts New Railgun That Launches Shells at Mach 7 · · Score: 1

    Whoops, left out the 0.5 in the KE calcs. Divide the times by 2.

    You also left out efficiency and sabot mass so maybe multiply the times by some amount.

  7. Re:IANA Physicist, So... on Navy Debuts New Railgun That Launches Shells at Mach 7 · · Score: 1

    OK, hot, yes, but wouldn't they need something combustible to actually erupt into flame? Or what am I missing?

    Heating caused by compression or by burning results in plasma - ionized gas - which you see.

  8. Re:Glitterboyz on the way on Navy Debuts New Railgun That Launches Shells at Mach 7 · · Score: 1

    is there a recoil on rail guns? or is this a joke?

    The recoil is lower than a conventiomal chemical gun for the same projectile and speed because no gas is accelerated with the projectile.

    However, rail guns tend to be immensely heavy beasts to withstand recoil and transversal electromagnetic forces.

  9. Re:100 watts?! on USB Reversable Cable Images Emerge · · Score: 0

    The "100W" spec comes from the USB descriptor having enough bits to accomodate 20A. Everything else is just bad journalism.

  10. VoLTE on Oppo's New Phone Hits 538 PPI · · Score: 1

    Would it do VoLTE or it's just a miniature computer with fancy Internet connection that gets turned off or downgraded when you happen to be in a "phone call" ?

    H2/F2 is an even more efficient mixture - in fact the highest energy chemical fuel we know of. But noone wants to touch it by a long pole. Hey, where's the pole? And my arms? And my lungs? Aaaahhhhh...

    Isn't "death" the only way off this planet too?

    Besides, colonisation of planets requires people reproducing there, as a result their descendanta being unable to live on Earrh. Sending people by rocket is too expensive to be used for population export.

  13. You'd wish to have such a box up a tree... on Open Source Tech Providing Mobile Communications In Developing Nations · · Score: 3

    In plenty of remote or rural areas of the United States there's little to none mobile coverage. As large carriers are reaping profits from high speed networks in populated areas they don't care a lot about a few potential subscribers at a farm.

    I beg to differ - IPv6 is still found only in most expensive consumer routers.

  15. Re:Toy project on Windows Replacement? ReactOS 0.3.16 Gets Themes, CSRSS Rewrite, and More · · Score: 4, Informative

    Actually the whole idea of ReactOS was to provide a binary compatible kernel so Windows drivers could be loaded unmodified.

    At the time ReactOS was started the lack of drivers was seriously hurting Linux. Meanwhile the situation has changed and drivers for Linux are no longer something unheard of.

    Also note that ReactOS and Wine share a lot of the higher level library code - in fact all libraries that are pure Win32 with no calls to native libraries.

  17. Re:PRAISE?!? on Mikhail Kalashnikov: Inventor of AK-47 Dies At 94 · · Score: 1

    The AK-47 is designed to win wars, not specifically to kill people. Read some Sun Tzu. With the normal military ammo (not the East German one) if the bullet doesn't hit a vital organ and with medical assistance there are very good chances of a full recovery. Can't say the same about many other firearms.

  18. But why? on Embedded SIM Design Means No More Swapping Cards · · Score: 1

    SIMs that can be fully reprogrammed by OTA already exist. All SIMs support changing the identity (IMSI) and a few also support changing authentication data (Ki, Op, algorithm). Most likely this is just a method to take away one of subscriber's freedoms - to become somebody else's subscriber.

  19. Re:What's next for fiber? on How Microwave Transmission Is Linking Financial Centers At Near-Light Speed · · Score: 1

    Line of sight communications means you need relays somewhere to go around the curve of the earth. We already cut huge latencies off intercontinental links by going from satellite links to fiber optics.

  20. Re:This should be amusing on The Dismantling of POTS: Bold Move Or Grave Error? · · Score: 1
    Early in 2013 the FCC decided to remove the subsidies for POTS and cell service in remote and hard to reach areas and instead sibsidize broadband Internet access. Now the operators may dismantle infrastructure that's not profitable even if some areas will be left with no service.

    POTS is not the only service affected. AT&T plans to shut down 2G service and make spectrum available for 4G instead and Verizon is considering something similar. Due to differences in coverage between these technologies some sparsely populated rural areas will be left with no cell coverage. Small carriers may be able to provide an alternative but it will take time and money.

  21. Re:Phoney issue on EU To Allow 3G and 4G Connections On Planes · · Score: 1

    Which would be odd, since once people see that talking on phones is allowed, they're going to just take out their phones and try to connect to the ground towers to circumvent the cost. I have no idea how well that will work.

    The on-board cell is fitted with jammers that prevent detecting the ground towers at all. This is to prevent phones from boosting power to reach ground.

  22. Re:Cost Benefit Analysis Needed... on EU To Allow 3G and 4G Connections On Planes · · Score: 1

    Operational costs are dominated by the connection to the ground stations (usually satellite but can be something else). Not sure how much licensing the systems costs, I know just 2 vendors and there are thousands of patents involved.

  23. Re: Best of both worlds on FAA To Allow Use of Most Electronic Devices Throughout Flights · · Score: 1

    At least for GSM and UMTS radios it means that the phone will fail to camp to the base station although it may be able to remain tuned to one. Note that in order to allow phones to find them base stations are required to have a frequency precision better than 0.05 ppm - that's about 50Hz at ~ 1GHz. Phones can still camp (but slower) up to some hundred Hz difference.

    Why didn't the meteorite leave a hole exactly the same size and shape as the object itself?

    The initial hole was probably smaller and less circular. However, the warm water rising from the meteor has melted the edge.

  25. Why not SCTP? on A Little-Heralded New iOS 7 Feature: Multipath TCP · · Score: 1

    If a new protocol is needed at both ends of the connection why not use a less experimental and more capable one like SCTP? It is heavily used in telephony networks for SIGTRAN and is also supported by some servers for SIP and HTTP.
