Yea, I hate it when people spam huge lists with random blog posts too.
I’ve started a blogging attempt that has, so far anyway, about 90%
Ruby content, most of which is directly related to Rails. Not all of
it is dedicated to this, it’s not that focused, but I am going to
attempt to post small tips as I discover them, and larger posts as I
write them. There’s a few things on Vmware vs Xen testing, Rails
security, and other tidbits there now.
If you want to have a look, click on over to
http://skandragon.blogspot.com/ and have at it.
I might decide to make it a bit more focused, but I’m sort of too lazy
to run more than one blog.
