The latest Channel 9 video focusing on Windows Live Messenger has arrived and this time it goes deep:
Ever wonder how the Live Messenger system works and why Live Messenger does what it does (and doesn’t)? Meet some of the developers and visionaries behind Windows Live Messenger and find out. We go pretty deep here, so fasten your seatbelts. This ain’t no marketing video… By the way, some of the Niners’ questions get answered towards the end of the interview. Enjoy!!
At 56 minutes in length (and 200MB+ in size!), there is lots of technical information to take in. Leah says you get to hear:

- The fundamentals of Instant Messaging
- Details on how Sharing Folders were built
- An explanation of add-ins
- The technical side of Yahoo! + WLM interoperability
According to one of the comments, Sharing Folders information is encrypted. Why not passwords?
If you’re a hardcore Fanatic, this is definitely one to see. Going by the still image, they appear to be talking about CS servers (eg. baymb-cs3.msgr.hotmail.com), so this is probably the most in-depth look provided by the team we’ve seen to date.
Ken Levy reports on the new developer initiative for Windows Live:
The Windows Live Platform is about opening Windows Live services to create shared opportunity for developers and businesses. Open Windows Live services via APIs and SDKs to 3rd parties to create a virtuous ecosystem that mutually benefits users, developers, partners, advertisers and Microsoft. Many of the developer centric services that we release will occur in stages, with new APIs available as well as improved and more consistent APIs with existing services over time. Some of our goals include Users are in control, easy for developers to make money, Simple HTTP based APIs, anyone able to build applications and components for about any operating system platform, browser, language, and device.
Ken was also interviewed at the recent Windows Live Hack Day in the Channel 9 video. Go forward to about 9:47, where he explains a bit about the Windows Live developer movement and the upcoming Web site.
A preview is expected to be available at http://dev.live.com sometime next week, with the full launch during June.
Sure are hearing a lot about the Hack Day event last month (see [1], [2], [3]). This time I’m reporting about a Channel 9 video called Windows Live Hack Day 2006 which was published on Tuesday. The summary is as follows:
How do you tryout a bunch of APIs (including Search, Expo, and more) all at once? You have a Windows Live ‘Hack Day’, gather developers together into one place, feed them and set them loose trying to build as many cool apps as they can.

Channel 9 has posted a 49 minute video interviewing some of the guys behind Windows Live Expo, formerly Windows Live Fremont. It looks like it was shot during November 2005, so at the time “Expo” was probably just an idea for a final name and it is referred to as Fremont throughout.
The interview gives a good insight into what Expo is all about, how it is meant to be used and how it is different from other classifieds & auction services on the Web. They also talk about the development and infrastructure of the service.
Channel 9 has published a video with Scott Swanson talking about the MSN Messenger APIs and “other Messenger related stuff”.
The video is 80MB and 21 minutes long, check out the post here.
It talks about the Activity API and the Worlds Best App Contest (not the UA Automation API).
