Other than that, coding for this machine is certainly not straightforward, and it is more an experimental device at this time. Certainly not something that'll give you a price performance advantage over conventional hardware, but as they keep doubling their qubit density every 15 months this may change in the not too distant future.
Yes, it only can optimizing a potential function, but that gives you a lot of mileage, because a huge amount of real world problems can be mapped onto a graph that can be embedded into the Ising spin model.
Look I am quite aware what the gate model quantum computer is and can do, but it is disingenuous to pretend that it is the only game in town, and the only such machine that is allowed to be called a quantum computer.
Two competing models have been shown to be computationally equivalent, namely quantum cellular automatons and adiabatic quantum computing. The latter you get if the machine can implement an arbitrary Hamiltonian. The D-Wave machine is restricted in that it can only implement spin-glass like Hamiltonians. But it computes with qubits. It is a special purpose adiabatic quantum computer. Deal with it.
D-Wave has published about chip architecture for quite some time now. You must be frequenting the wrong science sites.
Google for instance is following their overall approach but throw in hardware error correction. The latter has to be implemented via software on the D-Wave chip, which in essence is nothing more than a bunch of coupled josephson junctions (I heinously oversimplify of course, but there are now dozens of publication like this since D-Wave left the stealth mode).
I've been in IT for all my working live without ever having attended a software class, I majored in physics, coding was just something you were expected to pick up.
But I also always had a passion for history. Even as a teenage student I could have explained to Ronald Reagan (who I adored at the time) why giving Stinger missiles to Islamic warlords was a really bad idea.
Maybe we should teach history to all students just on the off chance that one of them becomes president?
... at a company that has some of the highest percentage of women in the industry, as well as the highest retention rate.
The key to both is ample benefits that allow for good life balance, and raising a family even if you are a single mom.
People here often complain about agism, and temporary work visas, not realizing that it all flows from the same source: The disregard for the "human resource" in tech.
Divide and conquer, turning the women in tech issue in yet another culture war, is exactly what the industry wants.
... this has nothing to do with the fact that France just experienced its worst terror attack ever, may be a bit shell shocked, and feels underprepared in ensuring the safety of such mass protests.

Doesn't mean one shouldn't praise him for what he does right. Setting an example like this for parents, who have the chance to take paternity leave, qualifies for such praise.
... I've been purchasing Apple products solely for the hardware quality, while just barely tolerating the software. The UNIX underpinning is of course great but UI wise Apple has clearly lost its marbles some time ago.
How they could go from NeXT Step's clarity (and beauty) to the current mess is unfathomable to me.
Nice to see that they are finally getting called out for it.
You seem to forget that France as well as the UK are nuclear powers. France already invited Germany several times to join its nuclear shield, but the anti-nuclear sentiments in Germany are too strong.
In terms of security the ground troops are more relevant.
Also Russia is mostly about business these days. Attacking your best NG customers is a bad business strategy (Ukraine on the other hand never paid the bills on time or at market price).
It's just that, a smart business move. The German market is the largest in Europe and the most sensitive to this issue. This is about revenue protection. Nothing less, nothing more.

Google ran the same test on the previous chip, before they committed to buying the machine. This test is for the new ~1K qubit chip.

There are some similarities but the story has long moved past that.
They sold the D-Wave One for about $10M to Lockheed. Figure that'll still get you a current model.
It's called "quantum annealing". Look it up.
Wait, are you telling me that nobody is going to put $10M down just to see if they can play their favorite MMOG faster?
Damn, there goes D-Wave's business model ...

It also confirms that D-Wave's machine uses quantum effects to speed up computation, but this point was never in dispute.
Boy, are you wrong on that count.
As to the term quantum computer. It computes with qubits, it's not universal, but in that it resembles some of the analog computers of yore.
So analog computers then weren't computers either, since they didn't follow Turing's definition?
It computes with qubits. I think it is perfectly reasonable to call it a special purpose quantum computer.

Chromium is plenty Open Source, where's the problem?

The most interesting inherently safe reactor design can also use nuclear waste as fuel and transmute it into less harmful radionuclides.
Well some people to this day like to point out that he build the Autobahn.
But I think I just call Godwin on you. Seriously.

Then again I live in Canada.

The trade with the US is obviously a big deal, but you don't have to be to closely allied to get free trade, and China nowadays is almost as important a trade partner as are the US.
So I think a case can be made that intelligence these days is the most important aspect.
Canada has to accommodate many US demands for sure. The country is entirely dependent on easy access to the US market.
For Germany it's more of a choice. Granting Snowden asylum risks to be cut off from American intelligence, not a good deal at the current time.
Would you rather be ruled by Putin?
Would you rather be ruled by ISIS?
Would you rather be ruled by Saudi Arabia?
Would you rather be ruled by USA.
As a German living in Canada I'd say you should broaden your scope.
