I was excited to see Facebook (FB) supporting login via OpenID (FB is a relying party), and I decided to give it a whirl. Here I list the results of my investigation, which describe the odd use of OpenID, as well as my wire level analysis which I hope you find informative. This post doesn't go into details of how OpenID works, if you're interested in that leave a comment and I'll put up such a post. FB uses OpenID in a way I've never seen before. In the "common" OpenID login model, you get a login page that shows you some sort of login via OpenID buttons. When you go to the FB login page there is no login via OpenID.   This confused me, but I went to my FB account settings and linked my google account to my FB account. (Attempts to link my MyOpenID account failed with a strange error message).  After some trial and error I realized that if I was logged into my Google account and went to the FB page than I'd automatically get logged into FB.

You know the drill, some app freezes. You try to close it, that doesn’t work.  You fire up taskmgr, sort by name, type in the name, and then hit the delete key to kill the process.  Easy with powershell: Get-Process | ? {$_.Name -eq "firefox"} | kill The real power here is the composability of powershell, for example you could also debug the process. Get-Process | ? {$_.Name -eq "firefox"} | Debug-Process Or if you’re not sure what’s going to happen you can always pass the –whatif qualifier: PS C:\Users\igord\Downloads> Get-Process | ? {$_.Name -eq "firefox"} | Debug-Process -whatif What if: Performing operation "Debug-Process" on Target "firefox (8204)" Happy Powershelling
