Kernel mode 에서 정해진 Stack 보다 많은 Stack 을 사용하면 System 이 Crash 됩니다. 즉 x86 에서 12kb 의 kernel stack 보다 많은 메모리를 사용하려고 하면 Bugcheck 0x7F 가 발생하면서 System 이 Crash 됩니다.

I’ve been wanting to redesign the site for a while, but never really got around to it. I hate to add something else to my to-do list or “goals for this year” but I think its necessary since I’ve knocked a couple of them off the list already.

The Fedora Project Announced today that they were releasing the Beta version of Fedora 11. Stupidly I went and downloaded it. After installing from the live CD which I had never done before (It went really smoothly) I had realized I’d installed the Alpha release

I’ve always had an interest for electronics and recently I’ve been exploring my interests more. Last week I sorted through my tub of parts and placed them in individual draws.

오늘은 WinDbg를 이용해서 remote debugging을 하는 방법을 알아보려 합니다.   원격지의 WinDbg 프로그램을 서로 Server, Client 처럼 TCP/IP나 named pipe를 이용해서 통신하게 함으로써 debugging을 하는 방법입니다.

On March 11th I presented at an invitation-only SharePoint Conference in the Midwest on Planning for Capacity and Scale. This was a redelivery of a similar session that was presented at the SharePoint Conference in Seattle last March
