Of course, back in the day we called it "stealth" and a "root kit" was what you used to "get root" on a unix box.. but hey, language changes. How about adding some infection routines to that puppy and letting it live?
When you decide how much the TTL value should be decremented by for a particular link you are not, in any way, restricted. You can decrement it by just one (this is what most routers do) or you can decrement it by 20.. what you can't do is decrement it by less than one. So if you setup your network to decrement by one for every second that a packet spends traveling over a link, as the RFC recommends, then you will have a problem for links under 299,792 km long and over 76,446,960 km long as you can't decrement the TTL less than one second or more than 255 seconds. But typically, a network will be configured to only decrement the TTL by more than one for a given link if there is another link that is faster. So if you have a 100 mega-bit link and a 10 mega-bit link between two buildings you'll most likely make the routers decrement 10 from the TTL for a packet traveling over the 10 mega-bit link and only one from the TTL for a packet traveling over the 100 mega-bit link. This will cause the routing algorithms to prefer the 100 mega-bit link. But it is completely up to you.
On the other hand, I think TCP has some actual time-based limitations:
To avoid confusion we must prevent segments from one incarnation of a
connection from being used while the same sequence numbers may still
be present in the network from an earlier incarnation. We want to
assure this, even if a TCP crashes and loses all knowledge of the
sequence numbers it has been using. When new connections are created,
an initial sequence number (ISN) generator is employed which selects a
new 32 bit ISN. The generator is bound to a (possibly fictitious) 32
bit clock whose low order bit is incremented roughly every 4
microseconds. Thus, the ISN cycles approximately every 4.55 hours.
Since we assume that segments will stay in the network no more than
the Maximum Segment Lifetime (MSL) and that the MSL is less than 4.55
hours we can reasonably assume that ISN's will be unique. So TCP connections to Pluto might be a problem.. Saturn will be fine, it's only 1.224 light-hours away.
Too much sun is bad. Not enough sun is bad. Umm, no. Sunlight is both a necessary part of physiological functioning and a cause of skin cancer. A "normal" amount of sunlight can cause skin cancer.
Take vitamins.. lot safer than being in the Sun. Do you have a family? Every minute you are in the Sun is another chance that you will get skin cancer and DIE.. then who will take care of your kids? Don't you think it is a bit selfish of you to be endangering your life like that?:)
Well, FSF have advised me in the past that any copyright is defensible, no matter how small it is in comparison to the rest of the work. Of course, if I asked them to defend me they would ask if I can assign them the entire copyright for the entire work and when I said no they'd bow out. That's just *their* policy, and one the SFLC has inherited it seems (which means it really was Eben Moglen's policy), but it doesn't mean you *can't* sue. I expect it is a cost saving measure. If you don't have copyright over the entire work then the defendant can file briefs claiming that the particular part of the work under dispute is not owned by the plaintiff and, even if it is trivial to show that they are in violation of copyright of a portion of the work that *is* owned by the plaintiff, it will take weeks and require the writing of very detailed, technical and lengthy briefs... i.e., it'll cost a lot of money.
So I guess if the only way you're going to afford to enforce your license is to get the help of the SFLC then you better get your ducks in a row.
No, the text you quoted is saying that *effectively* the TTL is a number of seconds argument, as there is no way for a router to indicate that it took less than a second to do a transfer.. so if your packet goes through 255 routers in under a second for each, it will die just as it will if it goes through 255 routers in over a second for each.
Dunno why you're replying to me instead of the OP but seeing as you are, I don't think he has no legal standing.. if he has been contributing code and not signing it over, then he owns the copyright on the work, period. The SFLC might not be interested because there are other contributors to the work and they'd have to get everyone together to have a strong case, but I don't think the OP even bothered to contact the SFLC.. everything he's said has the ring of a complete lack of research.. especially seeing as the first thing the FSF and the SFLC tell you when it comes to copyright violations is to make sure you have your facts straight and to not go sprouting your inexpert opinion all over your blog.
They don't have to provide this information on the website.. they have to provide it to their customers or whoever they actually distribute the software to.
the author states that there may be other files not being listed. He also states that he is not a customer and hasn't spoken to any customers.
He's already screwed himself by posting to Slashdot. If he is lucky Cittio will just ignore him. If he's not, they'll probably sue him for libel. His only defense then will be to show that he is right, and that will be pretty hard to do after Cittio have cleaned up any discrepancies they might have had in their distribution.. which they are sure to do before calling the lawyers.
For a start you claim:
When I brought up the fact that parts of Watchtower are based on OpenNMS, the client replied "I could not find one ounce of mention on their website to OpenNMS or any other Open Source code that is running on this product. That really irritates me." So what's all this then?
You also make the claim:
I should also mention that this client is in final negotiations with Cittio (they dropped their initial price considerably) so we're not talking a first contact cold call here - they are ready to close this deal without a single detail concerning their use of open source. Yes, and? They are not required to make any such disclosures. The GPL requires them to provide the source code or an offer to provide the source code when they distribute the software. As they haven't distributed any software yet, they are not required to provide any source code or offers to provide the source code.
What is hard to understand here? There are no routers between Mars and Earth.. therefore the number of "modules" that process a datagram on the way from Mars to Earth is zero.
It's actually possible to do 3d object recognition in real time eh? 60 objects you say.. hmm, might need support for about 100 times that before use in an autonomous household robot. Some general recognition of categories might be needed too.. otherwise just my cutlery draw will max out 60 objects.
I watched a stewardess snatch a mobile phone out of a guy's hand, turn it off and return it to him while we were taxiing. She then went and seated herself for takeoff and the guy started laughing to his mate and turned the phone back on. Soon as we were in the air she came and took the phone off him again and didn't give to back till the end of the flight, at which time she said "if I report this, you could go to jail" to which he replied "I *am* reporting this and you're going to get fired." Unfortunately, he's probably right.
As for de-boarding announcements going unnoticed, if they don't enforce them, they won't be noticed. For the situation you described, they should have said "we will be checking your connecting ticket at the door to the plane, please have it out for inspection or you will be sent back to your seat."
Heh, are you one of those guys who rolls his eyes at the people who swap seats before the plane takes off?
I know I am. Choose the seat you want when you book your ticket.. and if you don't have the option, hey, taking the bad with the good is what makes the seat lottery fun!
And so freakin' annoying. Is it really so hard to have some sort of order?
Stewards, please, at then end of each flight, get on the megaphone and say:
Can all passengers with luggage in the overhead bins please remain seated until passengers who do NOT have luggage in the overhead bins have left the aircraft.
That way the people who want to get off the plane before they go nuts and start punching random people can do so before the family of five start standing in the aisles trying to remember where they left their five bags whilst juggling their "personal items" and their duty free shopping.
And *then*, if you want to be really efficient, you could request:
Ok, anyone on the aisle who would like to get their luggage from the overhead bin and leave the plane, immediately, can now do so.

Not that I'd ever encourage such behavior.

Don't get me started on how bad exercise is for you.

I don't know if you're aware of this but daylight is bad for you.

Cause selling a solution is just as much, if not more, work than creating one?
And it is something that is done by sales people, not programmers?

Of course it does. Time To Live is a count of hops not time.

And then once they are out of the way:

But hey, I'm dreaming - it'll never happen.
