Setting up your KDBG environment for pussies.

Every time I have to setup a new environment, I completely forget the mess you have to go through in order to get your kernel debug world setup properly. So this is here to make sure I won't forget it ever again.

I do not run linux as a desktop, and I suggest that nobody else does. My development consists of OS-X, and VirtualBox with two (almost) identical installations of linux (whatever you want, but I use ubuntu here in my examples). Our secondary VM will be the host which we will be debugging, as in our primary box will attach to it via kgdb.

Step 1

Clone your VM - no need to do a full history copy, just a snapshot clone, call it something that won't confuse you later, like "fucktard69" if your main VM is "shitcocks666". It doesn't matter, shut the fuck up.

Finding a Ruby memory leak using a time analysis

When developing a program in Ruby, you may sometimes encounter a memory leak. For a while now, Ruby has a facility to gather information about what objects are laying around: ObjectSpace.

There are several approaches one can take to debug a leak. This discusses a time-based approach, where a full memory dump is generated every, say, 5 minutes, during a time that the memory leak is showing up. Afterwards, one can look at all the objects, and find out which ones are staying around, causing the
