Everybody will need new private keys.
What do you do with old coins? Satoshi's one for example? Or lost coins that nobody has the key for?
Do you set a threshold day, after which all unclaimed coins are just marked destroyed forever? If not, how do you know someone claiming some coins didn't use a quantum computer to get the key?

Citation needed? Symmetric encryption algorithms like AES (with at least 256 bit key) are considered safe even against quantum computers, based on some reasonable math/qm assumptions.

Not really. Your bank (and the whole web) can easily switch to a quantum resistant encryption algo when time comes.
For Bitcoin this is much harder.

One year before Fukushima:
> Computed risks for new reactors are lower than for current designs "when only internal events are considered," according to a 2009 report that the Nuclear Energy Institute wrote for the NRC. (That includes fires or pipe breaks, for example.) But when risks of damage caused by external events — earthquakes, for example — are factored in, the new reactors are no safer than older reactors. In addition, because utilities have no operating experience with the new reactors, the probable risk assessments are purely theoretical and not as reliable as years of actual operating data from existing plants.
> The new designs are engineered only to withstand a predictable sequence of events, something engineers theorize may happen. In nuclear parlance that is called a "design basis accident." The new reactors, like their older counterparts, are not designed to survive an unexpected sequence of events. That is the critical flaw, says Lyman: "Three Mile Island was a beyond-design-basis accident."

If it was soo dangerous, why didn't all those safety experts shut it down?
You don't see wood and canvas planes flying today.

Yeah, but I'm not talking about the original pair.
Since there is way more matter than anti-matter, shouldn't the p+ eventually hit something and annihilate?

Why don't the e-/p+ annihilate back into photons? Where do the p+ go?

Fukushima destroyed nuclear energy.
If the Japanese, with their image of professionalism, smartness, ultra advanced technology, and total dedication to their job failed so spectacularly to manage a plant, nobody will believe any safety promise anymore, at least in places where people are asked about it (ie: not China)
Now add the Chernobyl TV series on top, it will be replayed and memefied everywhere a plant is proposed.
Of course, this being HN, I welcome the incomming ban.

Pretty weird for a JSON parser to be platform dependent.

It was priced in the past, but the numbers seem ridiculously low to me:
> To recap, the estimated range is $200 million to $1.7 trillion, which as suspected comes with cartoonishly large error bars.

For once, it needs to be an attractive number for Denmark, more attractive than the unknown, but probably huge future value of such a big uninhabited place. $5T is about 12 years of Denmark GDP, and 10-20 times earnings is a good company acquisition price metric.
We are talking selling it forever. Just think how ridiculously cheap previous land purchases (Alaska, ...) now seem in hindsight.
Denmark is not really in the position to really use that place, even in the future. The only thing they can do with it is sell it, so the question becomes when and for how much.

Maybe the time has come for applications specific CPU variations?
One optimized for node.js tasks, one for databases, ...
