JUG Meeting Monday 30th Apr

[Brent Crammond]

Presenter:    Dave Eaves

Subject:       Garbage Collection in Practice

Abstract:      On the surface garbage collection promises to remove the burden of memory management from the developer. 

                   In practice, while the burden is significantly reduced, it certainly isn't removed alltogether. Some knowledge of

                   how your garbage is collected is needed, especially when the collector decides to bite back!

                   

Date:           Monday 30th Apr 2012 

Time:           6pm 

Place:          Alchemy - Commarc Building, 118 Wrights Road, Chch 

We will follow with the customary dinner at the usual Cambodian restaurant. 

Look forward to seeing you there.  Please come along with suggestions for other topics we should be discussing.

Have finally got myself organised to post the presentation as promised.

Following are some helpful links I found while researching. The video from Gil Tene (Azul) provides a good understanding of garbage collection if you can spare an hour (although the "what you can do about it" bit boils down to use their C4 collector).
