Why is it so hard to run a Bitcoin exchange? Internet
One of the chronic features of the Bitcoin landscape is that Bitcoin exchanges screw up and fail, starting with Mt. Gox. There's nothing conceptually very hard about running an exchange, so what's the problem?

How many people can you pay with bitcoins? Internet

An aquaintance wrote:

I think it's an open question as to whether that belief can sustain a meaningfully high Bitcoin price. There has never been a currency or asset that has been so easily tradable among every person in the world (even among anonymous people). ...

How do you turn a typesetting language into an identifier system? (Not easily) Internet

Unicode's goal, which it meets quite well, is that whatever text you want to represent in whatever language, dead or alive, Unicode can represesnt the characters or symbols it uses. Any computer with a set of Unicode type faces and suitable layout software can display that text. In effect, Unicode is primarily a typesetting language.

Over in the domain name system, we also use Unicode to represent non-ASCII identifiers. That turns out to be a problem, because an identifier needs a unique form, something that doesn't matter for typesetting.

What is Amazon Go really about? Money
Today's papers are full of puffy pieces about the wonderous new Amazon Go (pronounced, I hope, Ama-Zongo) in which you tap your phone as you enter and cameras watch what you do, figure out what you've put in your bag, and charge you for it when you leave. There's certainly no check-out lanes and few visible staff but the whole thing smells to me like a gimmick.

Great forking Bitcoins Money

Let's say I'm with the Chinese government and decide that I am tired of people evading currency controls and money laundering using Bitcoin. So we adjust the Great Firewall of China to block port 8333. We also add some proxies that allow some uncleared transactions from outside to flow into Chinese networks but not the other way, and keep track of which ones we let through.

Since a large fraction of the miners are inside China and all of the hard currency exchanges are outside, this will cause a pretty serious fork. No doubt people will start trying to evade the block, but the GFoC works pretty well, and any evasion will take a while to start being effective. It'd also be easy to tell who was trying to evade (look for outside transactions in the chains they publish) and send someone around to chat with them.

Even if the two sides are eventually reunited, then what? You have two separate chains, with overlapping sets of transactions, which would make any sort of ad-hoc hack to splice one chain onto the other impossibly hard, even if the anarchists in the Bitcoin world could agree to it. The bitcoin voting algorithm would eventuall make one chain win and the other one disappear. If some of the disappeared transactions were yours, how would this affect your opinion on Bitcoins?
