Comment Re:Proof that D-Wave is actually a Quantum Process (Score 2) 157

No, this proves that in some applications, D-Wave's machine offers considerable speedup over intentionally de-optimized alternatives. From the blog post:

We should note that there are algorithms, such as techniques based on cluster finding, that can exploit the sparse qubit connectivity in the current generation of D-Wave processors and still solve our proof-of-principle problems faster than the current quantum hardware.

In other words, the current D-Wave machine requires that problems have a particular, very restricted structure and they're only 10^8 times faster when competing with poorly-optimised solvers that don't take advantage of that special structure. if you use a properly optimised conventional solver, the D-Wave machine is actually slower. Google are hoping that future, more densely connected versions that don't exist yet will somehow retain the same speed while conventional code will get bogged down, but those don't exist and may never meet the performance promises that Google are hoping for.

If I remember correctly, their test results for the previous chip were later demonstrated to be rather misleading. The previous chip was indeed faster at solving the particular problem class it was hardwired for than a particular general-purpose solver running on a conventional computer, but someone managed to come up with an optimised solver that was faster than D-Wave at solving the exact problem class D-Wave was made to solve, on a normal general-purpose PC. It's not clear if the same applies to the new chip.

Uber's business model relies heavily on drivers using their own, standard insurance and not bothering to ask questions about whether they're actually covered. I think Uber have started offering their own insurance and raised prices to pay for it since someone got killed by an Uber driver in the US, but it's still inadequate (apparently less than they're legally required to have in Germany, and at least in the US all their drivers are driving uninsured whenever they're seeking riders).

Don't forget that by default, Chrome now sends all your passwords back to Google encrypted only with a password that Google have easy access to. (Only if you're signed in to Chrome, but they're incredibly aggressive about signing you in, so much so I don't dare log into Google accounts from Chrome anymore.)

By that standard Google Chrome itself has been malware for years - many pieces of software have bundled it in exchange for money from Google and made it hard not to accidentally install it, including I think Java, Flash, and various more shady products, and Google hasn't given a fuck.

Comment Re:passive scan isn't perfect (Score 1) 127

Barring another bug, it can - and probably does - scan for *all* ways to exploit it. The issue is that Android itself doesn't properly verify the certificate chain in packages before installing them, and Play Services can easily perform all of the missing checks itself and reject any package that fails them.
