November 19, 2008 Nov 19, 2008 11/19/08

PDC 2008 happened not long ago so I get to write another “what’s new in GC” blog entry. For quite a while now I’ve been working on a new concurrent GC that replaces the existing one. And this new concurrent GC is called “background GC”. First of all let me apologize for having not written anything for so long. It’s been quite ...

He’s live… he’s live not… he’s live…

I was making some code changes today and thought this was interesting to share. As you know, the WeakReference class has a getter and a setter method to get and set the Target which is what the weakref points to. See Using GC Efficiently – Part 3 for more details on WeakReference.   Note that the code below is only for illustration ...

I Am a Happy Janitor – Part 1: Finding garbage

August 18, 2006 Aug 18, 2006 08/18/06

Indeed what I do is very much like the job of the janitors – like the ones who clean your building, or janitors you see at a food court, or yourself when you are taking care of garbage at your house. Doubtful you say? Let me prove it to you. Finding garbage What do you do when you are having lunch with your friends at a food court and ...

Suspending and resuming threads for GC

June 7, 2006 Jun 7, 2006 06/7/06
maoni
First of all, suspension and resumption of threads is not really part of the GC. GC calls functions to do the suspension and the resumption as a service provided in the CLR. Other components in the CLR also use this service such as the debugger implementation. But it’s true that suspending and resuming because of the GC is the most ...

Large Object Heap

April 19, 2006 Apr 19, 2006 04/19/06

In 1.0 ...
