Internal workings of Windows Live Messenger

In IT, Opinion, Technical on December 31, 2006 at 8:01 pm

Take a look at the way the “Messenger Relay” system relays your Windows Live messages from one end to the other. (Click on the image to see the full view)

Here is how the whole thing flies around,

1. The user starts the session by double clicking a contact.
2. The user’s Windows Live ID credentials are sent across to the Windows Live ID Credentials server for further verification
3. The information is passed through a incoming only firewall to the dispatch server. This is the first point of connection for the message being sent.
4. Depending where the user is in the world, a connection will be made to the local notification server. There are main ones in Singapore, Dublin, Redmond and Reading. This keeps the connection between the two users alive, and keeps things updated such as user status, chat requests and email notifications from Windows Live Mail/Hotmail.
5. The message itself doesn’t go near the notification servers – it is passed onto the switchboard server which is the where all the messages and files are exchanged. The user starting the chat can talk to one user, whilst using another switchboard session to talk to someone else, and another switchboard session for someone else still – without even knowing it. Invitations, file transfers and video/voice chat are also sent through here.
6. The information is then relayed back through an outgoing firewall and checks the user is still online. If the user is offline by the time the message is ready to be received, then it’ll bounce back and be saved on the switchboard session until the user logs back on again. If they are online, they will receive the message.

Microsoft’s Free Ferrari Laptop Giveaway

In News, Opinion, Thoughts, Windows Vista on December 28, 2006 at 8:57 pm

You must have heard this…it’s one of the hot news in the blogosphere. “Microsoft is giving away some of the powerful laptops around, loaded with Vista, to some of the bloggers”. That’s the story.

Lately, the blogosphere was packed with the leaders of the blogosphere talking about whether it’s ethical to accept such an offer, is it okay to keep the gift or just give it away etc.

Robert Scoble thinks that it’s an awesome idea from Microsoft to giveaway the preloaded Vista laptops. Joel at Joel on Software says that Scoble was wrong and Microsoft in essence was bribing the bloggers to write about their product. It’s kind of a war of opinions flying around in the blogosphere.

I think it might not be an awesome idea but at the same time it might not be considered as bribing. Microsoft was not forcing you to write about their product and you are not obliged to write about just because you’ve accepted the gift. They say it would be nice if they review about it but they don’t force you to do so. It’s not a cheap marketing for them as well because the bloggers who’ve got the gift was already blogging about Microsoft products. So it’s not in anyway a cheap marketing campaign.

It might not be an awesome idea because it might trigger a biased blogosphere as bloggers might target that niche to be in line for the next years gift. The reviews might be one sided and might not be true enough. That way it wasn’t a great idea to send a gift preloaded with a specific product (particularly your own).

But I would take it as being a gift from Microsoft for writing all year about their product.

PS: Sorry for not posting to my blog for a while. I wasn’t in a position to post to my blog these days. I hope I should be able to resume my regular posting habit from now on.
