TCP does this by simply waiting some time between retransmits if it senses a lot of package loss Ah.. Interesting. I didn't know this. Just makes me wonder. What is the logic behind this? I can imagine it works nicely if all the connected devices are doing this. Althou I can't see how it helps if the bandwith (let's say a LAN) is saturated and only you are trying rarer and rarer to get your packet throught.
They represent TCP totally wrong. Not only that, they describe the whole network infrastructure wrong. No wonder I have trouble explaining how the network works to my sister, or even to my mother who happens to have his masters in tech. (Albeit in mechanical engineering)
Let's see.
"The sending computer transmits a pack, waits for a signal from the recipient that acknowledges its safe arrival, and then sends the next packet" No honey, thats why we have the buffers. So you could receive packets out of sequence and wait for the middle ones to arrive. This is why we have 32-bit seq and ack fields in the tcp header just after the src and dst ports. seq tells the packets order in the queue. Ack tells the seq ofthe next packet (from other peer) so we can use random increments to prevent spoofing of packets. Or make it harder atleast. But that's out of the scope of this rant.
If no receipt comes back, the sender transmits the same packet at half the speed of the previous one, and repeats the process, getting slower each time, until it succeeds. Umm, No. I'm not 100% sure but I think the network devices are dump thingies that talk to each other on predefined carriage frequencies. Thus, you can't really "slow down" the speed to increase possibility to get the packet through. And certainly this has nothing to do with TCP. Resending of failed packets is a Good Thing (TM). They are just sent again untill they reach their destination or the "I give up"-treshold has been reached.
"The difference (in Fast TCP) is in the software and hardware on the sending computer, which continually measures the time it takes for sent packets to arrive and how long acknowledgements take to come back" This is the only difference? Wow! Shit. We are definetely going to get faster speeds by adding overhead with this calculation.
Now, I'm through with my rant.
I really really would like to see an actual white paper how this works. There has to be more to this. By the sound of just these articles, it seems to me that someone was paid to develop new, faster protocol that would magically be backward compliant with TCP. Finally the persons couldn't come up with anything smart but gobbled together something that might sound plausible. Of course you can get "more than 6000 times the capacity of ordinary broadband links" by using your very own dedicated parallel LAN links. You just need fast enough computer to handle the TCP stack. You would also need some fricking fast BUS's on you computer to make any use of this bandwith. Remember, the hard drives, mem chips and other storages aren't exactly 'infinite' in speed either. If the demo consisted only of two computers exchanging data, there would be no need to estimate the speeds as it would be very unlikely to get packet collisions because of disturbance from other network devices. Also, again, that has nothing to do with TCP-stack. Again, this useless speed calculation is just more overhead.
And now I'm rambling.
Shit, why can't i just stop.
I'm angry, that's why:(
I hope someone would answer me with insight of what am I overlooking. This looks so useless to me.
I only scimmed throught the article and it seems they don't know what they are talking about. Anyway.
I could imagine using risky protocol for example for web surfing. My average browsing isn't so crucial I couldn't live with a bit of corrupted data. I wouldn't use it to DL any files however.
Should I use Ximian instead of apt-get? Sorry. This might sound stupid. See, I have never used Debian. I thought apt-get was just a package manager. As opposed to Ximian being just a window manager. Could someone straighten me up... This is what I have understood of the different parts of a Linux GUI:
Oh, that's brilliant. Do you tell your management that?.. Or, hmm, maybe you're a school-boy.
Yes, I tell my management that. I just turned down a Java component that was supposed to be one of my responsibilities. The manager was very cool with that and we just shuffled components with another guy.
No.. I'm not a school boy. I also know how to program with this piece of crap. I just feel it is not of any use.
You, on the other hand haven't probably had a touch with a real life. That, or you have got some silly Java project after high school so you don't have to fry hamburgers.
Oh yeah, almost forgot: My dad can beat up your dad and you must be an immature child because you might have a strong opinion about something.
Ok, I might hate Java because I have to nowadays deal with so many simpletons who don't understand how the computers work they are supposed to "program".
But what makes it a crime against humanity as well as one against humans is this: The Nazis attempted to wipe out an entire race with all their genes and their unique culture.
Isn't that called genocide?
Whee! Playing games is productive. I'm almost certain I have initially learned that word from some resource harvesting game.:P
I have still refused all projects that call for Java programming.
If it cannot be programmed with a real language, I don't wanna do it.
Are universities mainly teaching OOP with this pathetic piece of crap? Or why so many people seem to be insisting on using it?

Wow, it's new design is a radical departure from the original "beta" models, which looked a hell of a lot like a thicker Zaurus. I like it a lot (the design and the layout).
Damn. My initial thoughts were completelly opposite. I think the layout is weird and the thing looks like a brick:(
I already wrote a long rant about the device but came back to me senses and cacelled:)
Would not spend 449 on one of these things either...
I also, do believe, my vocabular versatility might very well spring from them countless hours of roaming within the endless corridors and passageways of Dungeons and Dragons.
On the later date however, my interest aroused towards role playing games involving computers. Still I preferred the textual context over the graphical glory of modern era. I still spend vast amounts of mi time in the game of BatMUD. Mainly developing it nowadays, mind you.
Could it be too hard to snoop on the 'lil radiowaves or magnetic fields used in these things? I mean.. I'm first in line swiping a mall with a highpower transceiver for these things, harvesting credit cards.:P
Atleast there has to be an attached pin number or something.
And when you have to enter a secondary authentication token (such as the pin), I see no advantages over magnetic strips.
Oh yeah, except. "magnetic". These things prolly would be harder to destroy accidentally.
When I was in the situation of singing a contract, I was rather desperate on getting a job. Thus I signed about whatever was passed before me.
Now I am stuck with this company. My contract basically denys me the right to associate in anyway with any clients the company might have.
When I signed the contract, I thought this wouldn't be a big deal because the company itself was so small it didn't have any clieants in which I wish to work.
But now. I think I actually have to switch country if I wan't an immediate job with some high profile IT company.
The contract binds me for 6 months in this field after I have left the company for any other reason than to get 'let go' by them.
I have a 6 month period of mandatory military service coming up. If I was to leave the company just before I go to army, I would have my freedom once again.
Now I am also very confident they would rehire me if I wanted. I'm also quite confident I would have plenty of options to choose from.
Unless they add some Jar Jar Binks of Middle Earth in there.
<rant> I'm still f*cking pissed they turned Gimli into a comic sidekick in Two Towers. I thought the original foolhardy and arrogant Gimli of the book was amusing enough. </rant>
Makes me chuckle. I used to be a regular in IRCNet, but nowadays I feel that it is just a breeding ground of script kiddies, egoistic assholes, social rejects and clueless friends of beforementioned social rejects who are about to be assimilated. I just google. There I can usually find a sensible answer to any question without the mental abuse.
Oops. This is off-topic too. Just when I thought I might get slightly positive Karma;)

Ironically enough, IE is unaffected.
Wouldn't "IE is unaffected" had sufficed?
I can't see any irony here.
And look at me! :(
Replying to wrong comment... Way to go!
Ack! Look at that expressions on the lil boys face.

I think something very wrong is happening there. I'm going to call the child welfare agency now!
Wait, I might be a bit late.

I wan't my share too.
Two posts stating that instead of insightfull the above post was infact retarded. I must agree.
These posts we're modded as Troll and a Flamebait.

XFree86 = Window server
Gnome/KDE = Graphical framework
Ximian = Window manager
apt-get = Something completelly unrelated

*Fizzl is rather confused with this terminology*
Sorry, I'm an uneducated person :(
:/
Could you tell me what exactly Jamison is? Whiskey?
Would Jameson do if this is whiskey?
I'd love to try this but I don't recall seeing a bottle with this name in my local pubs
Oh, that's brilliant. Do you tell your management that? .. Or, hmm, maybe you're a school-boy.

So your answer would be:
e) I thought the HTTP standard would be 4.01 already!
Which means you should definetely first read "internet protocols for dummies".
Ok, I'm a bit mean here, but I just couldn't resist.
