Comment Re:What exactly are they doing with it? (Score 1) 55

Why would anyone spend hashing efforts on those blockchains? And if you "solve" the need for hashing by making the blockchain private within a group of companies, where you expect none of them to attack the blockchains integrity, then your product is no different from having a MySQL database with restricted login ...

The reason Bitcoin exists is that they're the tokens distributed to make people spend efforts on hashing the blockchain. Without tokens you have no hashing. A blockchain thus cannot exist without a currency (defined as the value of those tokens).

Comment Re:we were just heading back into an ice age. (Score 2) 193

There have been several glacial/interglacial periods over the last 120,000 years.

No. Since the last interglacial 120000 years ago (the Eemian, warmer than the current) and the one we're living in (the Holocene) there has only been a glacial period (cold ... ).

It seems the paper thus says that our current interglacial is the warmest interglacial since the last interglacial. That seems very uncontroversial.

Regarding the XKCD graph it's contradicted by its own source. The graph claims to use Marcott et. al 2013 as a source (see top right). Now, study the graph carefully. Then read the following from Marcott 2013 (the abstract, even):

"Current global temperatures of the past decade have not yet exceeded peak interglacial values but are warmer than during ~75% of the Holocene temperature history."

Now study the XKCD graph again.

Comment Crashplan between friends (Score 1) 366

You probably have a friend with a similar question. The solution is that you buy a backup disk the size you need, they buy a backup disk the size they need, you both install it at the others place and then you run Crashplan between yourselves. That gives you off site version controlled backups.

Also inserting reality should ne done wilth cameras and not via clear lenses like Google Glass

Lag is the reason why inserting via cameras, processing, then displaying fails. We humans aren't really good at tens of milliseconds of disconnect from what our senses tell us and what we see.

Clear lenses (like Sony SmartEyeglass, in front of your eyes, unlike Google Glass) has zero lag on real world content (of course).

No, if the errors are systemic they can absolutely change the trend. Not only within a measurement system (human readers rounding to nearest half degree) but most definitely when you switch measurement devices (bucket intake on ships).

Most research in the world would benefit from having professional statisticians help out with the statistics. It's simply quite hard to get right. One principle that is never used as it should is the Bonferroni correction.

Comment Re:We all need to be nervous. (Score 1) 271

Remember this is the warmest month ever recorded, which makes it the warmest month since the last Ice Age (we passed the historic peak since the last Ice Age a decade or more ago). And that makes it the warmest month in the last 100,000 years.

Uh, no. Where did you get that from? "recorded" goes back to the mid/end of the 19th century - not further.

It was warmer than today for thousands of years during this interglacial (~8000 years ago) - known as the Holocene Optimum. In some parts, like anthrax-ridden Siberia, it was up to 9 degrees warmer than today.

(Yes, I can link the actual papers if you really don't believe it - but it's not difficult to put the keywords into a search engine)
