Wise words from the boogeyman
I find it much scarier that similar databases have been built and are already being doled out --for pay-- by shady private companies to, oh, the military and assorted other TLAgencies. Since that will be the case anyway, I'd rather have this one be free and public for all to see.
While breaking and entering is and will remain illegal, securing your own house is and will remain your responsibility and a good idea to boot. The /cyber-/ prefix and /on the internet/ suffix change nothing.
A comparable google maps overlay with facebook "I'm on vacation" notices has already seen the light, amidst predictable controversy. What of it? The demonstration ought to be enough for people to realise it's much smarter to stop publishing "I live here" and "I'm on vacation" together. Much like it's not smart to put notices saying "no milk for the next two weeks, dear milkman" next to the front door, for all to see.
It sometimes is good to realise again that the internet /is public/ and that therefore it is a good idea to keep your machines updated. You only have to keep track of security advisories for whatever software you use, not everything in the world. And a well-maintained distribution packs all that neatly together for you. All you need to do is regularly roll out the updates. But putting things /on the public internet/ implies that you do have to be prepared to put in the maintenance, or suffer the consequences.
In that, this is no more than a public service announcement.
