They are precisely incompatible because Blockchains are all about programmatic, self-enforcing arbitration. In a correctly-functioning Blockchain, there is no entry-point for non-permissioned humans to meddle with outcomes. This is not a bug but a feature.

Ethereum keeps hard-forking and has thereby undermined its legitimacy. The premise that code is law is central to Blockchains. The necessary corollary is that human-law is irrelevant within the space of outcomes on the Blockchain.

In Bitcoin, no human court can prohibit a transaction from going through, or being valid. Bitcoins cannot be confiscated by fiat. Full stop. Blockchains were designed to create a purer, more mechanical and reliable arbitration than the courts can give.

Cython is really fantastic. It makes you realize that there is often not a huge reason to leave Python if that's what you are comfortable with. The community has simply produced so much.

Log is often used because it makes linear proportional returns. It makes the most sense when gains are considered derived from the principal, ie proportional returns from capital. See an example below.

As others have mentioned, maximizing log is equivalent to maximizing the underlying.

But when considering returns on accruing capital, a 20% loss is much worse than a 20% gain is good, and similarly a 100% gain is much less good than a 100% loss is bad. This is correctly captured by taking the log. In the case where money is simply accrued from some external source, and their is no proportional return, log isn't necessary.

I don't think that is evident at all. Clear writing will resonate with the reader far more than hackneyed, pretentious constructions.

Many of the best communicators in history successfully employed "simpler" verbal constructions than those Orwell rails against.

barisser | 9 years ago | on: An astute online comment has some wondering whether Brexit may ever happen

Whatever your opinion on Brexit, it would be a miscarriage of democracy to ignore the referendum's result, even if it is not strictly legally binding.

If Leave can win now, it will garner more support if the public's will is neglected.

Also the comment takes it as a foregone conclusion that triggering Article 50 would spell the political demise of the sitting Prime Minister. Isn't this a dubious assumption? We're seeing short-term market reactions today, but it is a very different thing to assert that the long-term impacts are as suicidal as is commonly believed.

Software is almost always flawed to a certain extent.

The problem with Ethereum is that you can't push a fix to your contract.

What concerns me is that they want to do a soft-fork to handle just this case. One shouldn't fiddle with the protocol every time something like this happens.
