Today I was curious about doing OpenID delegation. I wanted to use my blog (coderich.net) as my OpenID and have it authenticate via another provider. I ended up choosing Google as the other provider, but Launchpad would’ve worked just as well for me, I think.

I found a helpful stackoverflow answer that explained how to Delegate OpenID to Google. Then, I found an OpenID Delegate Plugin for WordPress. It didn’t use the openid2 link names, so I updated the plugin slightly so it provides both the old tags and the new ones; you can download my version 0.2.

On my test Windows Server 2008 R2 Server Core install, I’ve been seeing period CPU usage spikes on what’s basically an idle guest. Task Manager showed an instance of svchost was the offender. I used Process Explorer to narrow down which services it was running. From there, I had to use the process of elimination to find the CPU hog.

I started by disabling the Windows Update service. Even though that turned out not to be the problem, I stand by that. There’s no reason to have a service running when we’re going to run the updates manually.

It seems the IP Helper (iphlpsvc) service was the culprit. Some web searching suggests it’s used for 6to4 (or Teredo) tunneling. We’re not interested in host-tunneled IPv6 connectivity; eventually I want native IPv6. So, I just disabled the service. The guest’s idle CPU usage seems to hover around 1% now.

I would encourage everyone to visit ashtonshepherd.com and listen to her song “Sounds So Good”.

Wait for this gem: “’cause there ain’t nothin’ like the sound of a cooler slushin’ on the bed of your truck.”

Now I actually enjoy a lot of country music, but wow. I just can’t get over how truly bad this line is, both in terms of lyrics and sound.
