- Researchers locate flaw in Bitcoin protocol
According to Slashdot’s brief on research from Microsoft and Cornell, the problem is misaligned incentives. Nodes may not always be encouraged to relay transactions to the rest of the network. Slashdot links to the paper they produced proposing a scheme to provide a stronger reason for nodes to relay, to do what the protocol and overall scheme requires to operate well.
- Why you may not be as anonymous in your blog as you think
Writing for Wired’s Epicenter, Andy Baio explains how he was able to track down a highly critical and inflammatory blogger who was targeting the usual Apple supporters. Despite the blogger in question, who Baio (rightly) declines to identify, using most of the usual means to hide his or her identity, ultimately they were unmasked via Google Analytics. In short, in looking at the background traffic on the anonymous blog, Baio was able to extract the identifier Analytics uses to aggregate traffic stats to a single Google account. There are now apparently a couple of services that will perform reverse look ups on this ID meaning that anyone looking to protect their identity may need to create a separate, unlinked Google profile if they want to use the search giant’s web traffic tracking tool.
- MIT developers chip to simulate synapse
Pesco at BoingBoing linked to this piece that seems very familiar. I think the space of researchers trying to model components of brains directly in silicon must be getting crowded. All the same, this is promising for at least understanding how higher level cognitive functions arise from low level structures like neurons and synapses.
