Bottom line up front; the GPL license is viral.
I have had a lot of discussions with people about software licensing, and it amazes me how few of them really understand them, especially the GPL. I’ll do a quick comparison of licenses:
EULA: sharing is evil
BSD: sharing is not evil
GPL: not sharing is evil
Disclaimer: I have no affiliation with ksplice, I’m just a guy who knows something about hot-patching the linux kernel and figured out how this ksplice thing works. I strongly agree with the sentiment that the ksplice raw utilities is not for general use. In fact, Ksplice says in the distribution of these tools:
Without the appropriate expertise and safety infrastructure, the raw utilities can create subtly incorrect rebootless updates, which can have serious consequences.
I have recently set up my website behind the free reverse-proxy hosting service CloudFlare. So far I have got to say I’m very satisfied with the service. I currently have a free account, time will tell on whether or not I feel the need to upgrade to a Pro account. Not 100% convinced I need it at this point.
