    In school the child born in march are a half year older then thos born in august, but are put in the same class (at the age of 5 that is is a huge difference. ) and will affect their behaviour.

    The exception in the DCMA states "Computer programs that enable "wireless telephone handsets to execute software applications, where circumvention is accomplished for the sole purpose of enabling interoperability of such applications, when they have been lawfully obtained, with computer programs on the telephone handset."

    A console is not a wireless telephone handset, so that circumvention exception is not litterally applicable I would think.

    No, it can happen more subtle.

    Intel can put some minimalistic windows 8 on a next-gen phone (/tablet), but unless MS creates a cheap oem license for it will be too expensive to compete with a linux like license. For high end $500++ devices it is not a problem. but in the end they want to create a 200$ device as well, where a 70$ oem license will be a too big cut.

    I disagree, PSN requires a certain firmware version. All sonly has to do is create a new firmware version (firmware can contain level 0 code) that does the the check and require that firmware.

    Blacklisting the most common hacks will be enough to discourage coming online with a jailbroken PS3.

    In theory you can create a hypervisor that is completely hidden like the blue pill hypervirsor, But creating a completely undetecable rootkit is not trivial, especially on the PS3 where you can detect such beast vai timing attacks since the difference in available hardware is small

    Note that the hypervirsor currently does not do security checks, those checks are done by the loaders, not the hypervirsor.

    The parent in exaggerating, but wmem_max can be easy tuned up a lot maybe even to 1 GB.

    TCP (or any protocol) cannot simply handle a large jitter due to extrermely large buffers.

    If the network price is higher than ram prices, the mistake is very easy made to make the buffer bigger to reduce packet loss on a particular link.

  19. SFQ on Bufferbloat — the Submarine That's Sinking the Net · · Score: 1

    SFQ implies adding an extra buffer.... and this extra buffering will cause the death of the internet.

    The solution is that all hops keep a low buffer, and use the same time (not size) the buffer. That will solve the bufferbloat, but it will not solve other problems.

    The description of the parent comment is correct, but it is an exaggeration, and exaggeration of buffers (to minimize packet loss) is exactly the cause of the bufferbloat.

  20. Re:Tos field in ip header on Bufferbloat — the Submarine That's Sinking the Net · · Score: 1

    I can see some problem immediatly:
    -There is no good QoS interface (at least not in winXP) for applications to set bits.
    -Misbehaving application (everyone thinks they are the highest priority, but in reality p2p file exchange should be low priority). That is an immediate reason to ignore Qos.
    -There is no incentive for ISP to follow this Qos Bits. You don't earn money by SOME serving traffic faster or slower.

    by the wya, good QOS dos not solve this bufferbloat. large jitter will cause tcp/ip to misbehave on congested networks. (And QoS is there to hide some of the the congestion, not to prevent congestion)

    I Don't dare think about relying on ECN in tunneled protocols (VPN).

    I am not saying that ECN is bad, but it is a differnet discussion from bufferbloat. The problem is large buffer causing a jitter in the the delay. ECN might help in minimizing congestion, but if the end result of ECN is that ECN clients are slower than non-ECN clients i know what will happpen....

  22. QoS on Bufferbloat — the Submarine That's Sinking the Net · · Score: 2

    QoS does generally not work beyond the first hop. Your provider most likely will drop any QoS data. Some providers wil try to make their own QoS systems (e.g. to show a low ping). However if the lantency has a great variance due to all kind of buffers any algoritm will get the bandthwidt wrong.

    QoS based on network types will get it wrong. For pure browsing /downloading it is relatively simple, but for VPN Encrypted skype udp traffic, game data it will never be optimal.

    And as the blogger wrote, there is not a simple solution, because the end user has a "dad the internet is slow today" mentality. Couple that with a "reinstall your windows" helldesk and the solution becomes VERY HARD.
