Well as expected videos of the launch showed up on YouTube pretty quickly. Sorry to those of you with dial up(mom and dad), but for those of you with high speed internet check out my launch. Woohoo!
Family, Cuz You Just Have To Keep In Touch
So my bro and I were having a discussion about network speed and and download speeds and such. His last email to me follows.
Riveting isn't it? ;) xoxoxoxo
Ok, I think I've got it figured out, There were a number of things that confused me, I was getting Mega bits and bytes mixed up for one. I was also confused by what I was seeing in network connections. There are 2 connections, 1st is my Local area connection, connected at 100 MBps which is basically the speed limit for ethernet right? And has nothing to do with the speed of my connection. Thats the connection that I'm using. The 2nd is called 1394 and basically has nothing to do with anything. I suspect that there is nothing I can do about speed from here. My speed has more to do with servers, comcast servers and any other servers I connect to. It's quite possible that comcast has crappy servers in this area or maybe they are overloaded. So basically its traffic and servers, and if I want to do something about my speed I should contact comcast. Sound Right?So he basically had it all figured out, but I couldn't leave it at that and wrote back the following dissertation. Ah, the loving communication of two brothers.
The 100Mbps connection is basically the max speed of your local network, i.e. whatever you plug into your network card/mobo port. Your wireless connection maxes out at 45Mbps. Now cable and DSL don't even approach these speeds....yet. Most DSL providers have plans for 768kbps, 1.5Mbps, 3.0Mbps and up to 6.0Mbps. The physical limit on DSL download speeds isn't much higher than 6.0Mbps. Newer DSL technologies, ADSL+ for example, are offering much higher download speeds, but it's not available in most places yet. Cable companies are offering similar plans as DSL, but they are also offering much higher speed plans as well, upwards of 10Mbps. The major difference between cable and DSL is your attainable speeds. With cable you're sharing the same connection with everyone else in your area. If you're all using it at the same time to download porn then everyone takes a hit on their max download speed. With DSL you have a dedicated line to the internet and assuming that you have a good, clean line and are close to the central office then you will get your max speed, minus TCP/IP overhead, regardless if your pervert neighbor is downloading crocodile fisting pics and movies at the same time you are.
Verizon has come out with a new technology called FIOS that is vastly faster than regular DSL and actually has the capability of reaching and exceeding the ultrafast speeds advertised but never provided by the cable companies. Alas, one must be in a verizon area to get the FIOS.
So until we get wormhole technology for our downloads the limiting factor will be the speeds provided by whoever the ISP is that provides you with your entarweb connection.
The 1394 network connection you see is for the firewire port you have somewhere on your system, either on your mobo or on the soundcard. Technically you can do a type of networking through it, but all I've every used it for was to collect dust. Especially now that USB 2.0 is such a fast and reliable standard.
1394 = firewire port
Now, there is a higher speed available for your internal network speed. It's called Gigabit and it's at 1000Mbps. To make real use of it you would need a router and at least one other computer with hardware capable of the this speed. Even then you would only be able to transfer data between those computers at that speed. Again your internet connection is way, way below these speeds even if it was working as fast and efficient as it possibly could.
So LAN, local area network, is the term for your network inside your house. WAN, wide area network, is the term for connection to the entarwebnets. Wi-fi is a wireless type of lan, just not quite so local since if you're not careful since you'll share that wi-fi connection with all of the cheap thieving bastards who live near you.

The launch went off without a hitch. Satellite separated from the rocket with no issues. Ground stations started receiving signals less than an hour after lift off. Woohoo!

The Big Day
Well we've been really busy and I haven't had a chance to post until now. Hopefully someone will see this and get to watch. We're launching tonight at 8:20PM Eastern. That's 5:20 for you west coasters. Here's a link to the ULA website with info on how to watch the launch.
Wish us luck and send us good thoughts.
