Yahoo's id can be used across its network (email,groups,answers etc),and Google's id can be used on its network (gmail,gtalk,blogger etc) and Microsoft has Passport (mail,Spaces,and all MS services including Windows itself).

But what about the other majority of internet not owned by Y!,Google or MS? Its where OpenID comes to the rescue.

Started in 2005, OpenID eliminates the need for multiple usernames across different websites.Its designed by the OpenId foundation which provides it as a open source implementation. OpenID can be signed up using one of the OpenID providers. Once signed up,it can be used across the network of websites that support OpenID.OpenID foundation claims that OpenID is supported by more than 50,000 websites.

Some major websites include blogger,wordpress,livejournal,scribd,digg,dailymotion,facebook etc.,and more and more websites are starting to support OpenID gradually.

OpenID offers users ease of use and there is no need to sign up in websites supporting OpenID.

For website owners,the advantage is that more users will be signed up for their website since users dont need to signup separately, and users only need to sign in into OpenID and join the website.

So,users can easily join an OpenId supporting website.Thats a plus for both users as well as website owners.

Moreover, OpenID can be easily implemented by website owners.

And regarding security,the OpenId password will not be submitted to the website, it will be submitted only to the OpenID provider who acts as the middleman in the sign-in process.

Yahoo started to support OpenID in 2008 as a OpenID provider.The implication is that existing Y! ids can be used as OpenID logins (username/password).However, it needs to be enabled separately.

Just go to openid.yahoo.com and login with Y! username/password and enable OpenID.

After that, Y! id can be used to login into any OpenId website.

An important thing to be noted is that the Y! username/password should not be entered directly into any website's login boxes.Enter yahoo.com in the OpenID field.The browser will redirect to Y! authentication servers.Y! username/password should only be entered in Yahoo's login page.

Even Google and Microsoft are OpenID providers.

Note:

OpenID providers: websites that allow to create OpenIDs (trivially, Y!,G and MS allow creation,but they can't be used for login in their own networks,but usable on all websites implemeting OpenID)

OpenID websites: websites that allow OpenID to be used as a login method (websites that allow users to login)

Apple released the iphone/ipod firmware 3.0 version recently.
The catch for ipod touch users is that this firmware upgrade is that it activates(unlocks) the bluetooth chip in ipod touch.Ever since it was released,there was no bluetooth option in ipod touch,but it had an option to connect with Nike gadgets.
The chip that was used for Nike is now being unlocked to provide bluetooth access to ipod touch,enabling multiplayer games,wireless headphones etc.
But, there is a catch here too, the firmware upgrade is not available for free.
It needs to be purchased for 9.95$ (USD). (file size 257.8MB)
Normally, it is the duty of the vendor to provide firmware updates for free.
Imagine Nokia selling its phone's firmware updates,or Microsoft selling service packs!
Apple has monopoly in this segment since they are the leaders.

And then, there is this problem of Apple bundling stuff.
Quick time is bundled with itunes.Why cant Apple integrate quicktimes' codecs into itunes itself?
I have itunes 8.1 and its been bugging me to upgrade to itunes 8.2,but i declined the upgrade. So, what Apple did was to bundle the ipod touch 3.0 firmware with itunes 8.2!I need to upgrade to itunes 8.2 in order to upgrade to 3.0 firmware which i bought for 10USD.

All in all, the bluetooth unlocking is too good to resist.
The upgrades in 3.0 include,
