Yes, you are misunderstanding, there are 2 ways a provider gets access to other networks, 1 is transit, the other is peering. Transit is, you (A) get all routes a provider (B) has to there network and other networks it knows about. Peering is when you just get routes about there network (provider B) and there customers networks (the customers that buy transit from B).
Transit is the kind organisations pay for, peering is usually free, but doesn't have to be.
A provider is a Tier 1, when all they have is peering and still have a connection to all the whole internet.
Sprint and Cogent are both a Tier 1 providers (Cogent only since June or July or something), thus if you have an organisation that is only connected to one transit-provider and it's one of them, you now don't have routes to the other anymore.
Organisations that buy transit should always connect to several transit-providers, Tier 1 or otherwise. Otherwise you didn't need all the extra stuff: BGP, ASN, dealing with routers, dealing with routes, etc.
Anyone organisation that is stupid enough to only connect to one Tier 1 provider is dumb, because that provider doesn't have any other peering or transit if a problem like this emerges.
The reason these problems exist, is because Cogent pretty much has the lowest prices in the industry, not just the Tier 1, but all of them.
So when you buy transit from Cogent, also buy from others. In general terms: atleast get 2 transit providers, always (unless of course you are large enough to be a Tier 1-provider). Otherwise it's like a single point of failure and you could just have gotten yourself a 'normal' internet connection.
Cogent does not buy transit [0] , they've become Tier 1, my guess is Sprint isn't happy with how much traffic is flowing over some connections and wants money (think: paid peering).
This is kind of what the kernel developers and distributions makers are doing with the next versions of Linux-distributions. They make a list of things that should go into the filesystem cache at boot and load them all in one go. Reducing disk search-operations by many fractions.
Yes you are right. What I meant to say was, with a distribution all software you install is downloaded from the same mirrors. For a lot of people that set of software is enough, they don't need anything else (web, mail, office). And there are checks in place to make sure the packages are authentic.
Which is something windows of mac users generally not have in place. Most just download from the first website Google comes up with.
That's why people should be using Linux distributions and packing systems which download and check md5's and sha's, etc. Then people would not have that problem.
The problem has always been, Rasterman is the projectleader and he never got a job where he could dedicate all his time to the project. If that would have happend he could have done some real 'damage'.
He had been working on embedded before and he alwasy wanted to make E17 be usable for that as well.
Have a look at this video of e17 running on an Compaq/HP iPaq from some years ago (the webserver says last-modified: 23 Oct 2004):
Maybe they should create something people actually want to use, instead of have to use because of application compatibility and then people also would most likely rather use the older version because of the same reason (XP)
maybe by that time they will have invented time-machines and he could send back a message telling you about the release, then again, if they did, he could have done it 'now'...?
It depends, VLC and mplayer work pretty good on Windows, maybe a little better on Linux. But they are Unix/Linux programs ported to Windows. So that's a bit like cheating.

Probably because the webserver does a DNS-check and it's waiting for a timeout. That's atleast what I see with apache.
Does your computer need such a complicated BIOS then ?:

I really doubt it, something like coreboot is more then enough.

I think he's probably talking about a restore cd or similair.
That's clear then, those people have already reached there limit.
Sorry, that was Hamm I think, not Potato as I wanted to type.
I've build a DNS-server on a 386 with Porato ones. That also worked (for as long as it was needed).
I think there might be a limit on the amount people should borrow to keep an economy strong, I'm just guessing here.
I hardly know of any organisation that actually does this. The Rabobank ( http://www.rabobank.com/content/about_us/ ) however is an example of this principle.
It really isn't so hard to understand.

Now he works at the company working on the freerunner and he actually gets that time to work on these things and thus it's moving forward again.

It's not just in Debian, I've seen the same in Ubuntu.
"We've come a long way since those dark days when networks were afraid of the internet."
Without the context this is a really strange statement as internet means interconnected networks.
Just like Windows, it isn't Open Source either. Maybe if you want to use Open Source you might look into not using Windows...?
maybe by that time they will have invented time-machines and he could send back a message telling you about the release, then again, if they did, he could have done it 'now'...?
Maybe now that you are in teaching, maybe you should have a look how others do it, here is an example:

I've been watching these for a while now, I liked them (although to much beginner for me, it's a nice way to get to know a 'new' language).

I like how you were able to get a car analogy in there. :-)
