Starting from scratch

In an attempt to keep myself motivated to blog on a semi-regular basis, I’m re-inventing my blog and starting completly from scratch.

I will be blogging about the book I am currently writing, the grsecurity kernel build system I am building, and the rogue-beret repo I will have online shortly.

Well, time for bed. Been sitting at this computer all evening. Have a good night!
