Interesting empirical results using JDK 7u21:
Full GC duration depends on the number of objects allocated and the locality of their references. It does not depend that much on actual heap size.Reference locality has a surprisingly high effect.
Occupy.here began two years ago as an experiment for the encampment at Zuccotti Park. It was a wifi router hacked to run OpenWrt Linux (an operating system mostly used for computer networking) and a small “captive portal” website. When users joined the wifi network and attempted to load any URL, they were redirected to http://occupy.here.

Mark Jeftovic is on fire after receiving yet another “take down this domain or else” mail from the City of London police:
We have an obligation to our customers and we are bound by our Registrar Accreditation Agreements not to make arbitrary changes to our customers settings without a valid FOA (Form of Authorization). To supersede that we need a legal basis. To get a legal basis something has to happen in court. […] What gets me about all of this is that the largest, most egregious perpetrators of online criminal activity right now are our own governments, spying on their own citizens, illegally wiretapping our own private communications and nobody cares, nobody will answer for it, it’s just an out-of-scope conversation that is expected to blend into the overall background malaise of our ever increasing serfdom. If I can’t make various governments and law enforcement agencies get warrants or court orders before they crack my private communications then I can at least require a court order before I takedown my own customer.
