What the GP talked about is there for a reason. If you used UDP in a congested network, you'd probably get lots of packet loss. If you tried implementing your own retransmision algorithm, you'd probably get the same results as TCP with no congestion control algorithm: extremely low throughput, even though you have enough bandwidth.

Just don't do one thing at once and you won't suffer the penalty as hard as you would one connection at a time.

(and I'm not sure about that 40% figure, TCP RENO is probably more efficient, and you're not supposed to connect to the net with something worse than that)

And since the penalty is per connection, the ISP doesn't suffer the way you would. Their pipes probably fill to capacity (or close), provided there's demand.

What are you, another MS shill or just living in a cave?

The MS monopoly is not just Microsoft advertising Microsoft products in other Microsoft products. It's more like "embrace, extend and extinguish".

When Microsoft bundles something, especially if that something is related to a standard, they bundle their own "special" version, which is just incompatible enough. Then the proper standard fails because a large percentage of the users use that "special, not quite standard" version of the protocol/software/whatever.

10 Years after the first browser war, we're still stuck with some "IE6 only" web sites, got it?

There, think that's more on the point now. I wouldn't at all be surprised if some members of the US party in these negotiations isn't secretly crying out "Booyah!" while putting on their "Oh dear, I'm sorry that happened..." face to the lobbyists who give them money.

I'm not so sure, considering most of the leaks appear to have come from the EU. If there were a will to be open about the treaty, I think we would have seen at least a leak from the US legation.
Not seing leaks probably means that either there's no or little intention to be open, or while there might be the intention among the grunts, the security is really tight (because probably a big fish does not want the leaks to happen).

Comment Re:The apache video is polarising (Score 1) 116

While the van might have not been an ambulance, it was clearly unarmed and picking up a wounded man, not "weapons and bodies" as the chopper pilot said. I find it rather difficult to excuse that behaviour.

While the first attack might be reasonably attributed to an error in judgement, the other incidents seen in the video (the pilot wanting the reporter to pick a gun so he can finish him, the attack on the van and the missile attack on the building) are pretty much the action of trigger happy men.

As a minor detail, he really made a mistake when he identified the camera as a RPG, since an RPG-7 has a distinctive shape, unlike the one in the video. That shape might be confused with a M-72, an AT-4 or even a bazooka (a big tube), but hardly with an RPG-7 (a small tube with a big cone in one end). He might have been thinking in other types of RPG, but that is unlikely.

MHz = 1,000,000 hertz, and refers to the clock rate. The clock rate is the number of cycles per second a processor executes. Each cycle is exactly one toggle - either a zero or a one.

Because this is used in the processing of the data, and doesn't necessarily have anything to do with data itself, there is absolutely no way to relate the clock rate to bits or bytes.

These same clocks drive your buses and communication lines. There's your relationship with data.
When you download a file at 1 Mbps, you're getting 1000000 bits per second. And that's because there's a 1 Mhz clock somewhere triggering the hardware to put those bits in the wire.

Basically anything based on a clock, like communication lines, use base-10 prefixes.

Okay but will the UDP packets which cause the problem be well formed enough to be routed into your network from outside?

Yes, they will.
The packets in question cause problems because they cause a buffer overflow in a parameter sent in the data.

The NIC accepts normal UDP packets for port 664 and then analyses the packets to see whether they use a certain protocol. If that's correct, the NIC responds to the packet itself and the OS never sees it.

The tampered packets trigger a buffer overflow by using a username (in ASF 2.0) that is longer than its maximum allowed length.

So, basically, they are perfectly normal UDP packets.

Personally, I don't see why something like Phalanx wouldn't be the right system to use against really fast missiles.

Because supersonic missiles travel so fast and phalanx-type systems have such a short range that in the time it takes the phalanx to reacgt and engage the missile, it'll be so close that it'll blow right next to the defender.

It might not sink the target ship, but all that 'crap on deck' (more like shrapnel) could easily disable most sensors and cripple the ship, leaving it out of combat anyway.
