BSD vs Linux ?

[Arthur Chan]

Hi ! Recently there was some chat about "real Unix". Was there any seminal comparative studies between FreeBSD (or even NetBSD) and Linux ? BSD has been around a long time. Why Linux ? Why not BSD ? Drivers ? Platforms and chipsets ? Are there anything one can do with Linux which one cannot do with BSD ? Does BSD manage kernel memory better and does Linux swap more "aggressively" ? Is there a JVM for BSD ?  Does the Apache staple  run on BSD ? Questions upon questions... The truth is out there somewhere.
