You know how mobile networks made lots of money by letting third parties charge things to people's cell phone bills? I think 21 is trying to build carrier billing for everything. If everyone has a hundred dollars a month of mining pow

This is one of the huge benefits of taking a compilers class. You'll probably never write one, but you'll understand the languages you use better.

These banks clearly disagree with you. It's not cryptographic protection of data. It's the cryptographic audit trail that's useful. No one can break the rules of the system except for validators, and everyone instantly know

No hashpower is required. If you have a fixed pool of validators, just rotate through the validators to pick who creates the next block.

Sure, but if you're reaching consensus on a cryptographic chain of transactions, that's exactly what a blockchain is. Mining is not an integral feature.

Access isn't free, but anyone can write to it without permission. That makes it public. Individuals couldn't compete with SWIFT because they had no way to coordinate their actions. Public databases change that. The first phase wil

Blockchains can be built without 10 minute block times or wasteful proof-of-work for mining. You can just pick people the users trust to make blocks or use proof-of-stake mining. Blockchains are harder to break than most corporate databases

The "shared ledger" analogy for blockchains is limiting. If you want to understand the potential applications, you should stop using it in your thinking. Blockchains give us publicly writable databases . Such a thing never existe

Employers are subject to market forces just like everyone else. If they need workers in order to make money, but workers can't afford to get to work, they will pay more money. Not by choice, by necessity. If you don't believe that

The alternative transport mode is shared rides. Those are easy today with ride hailing apps. People who don't want to pay the full charge will pay a fraction of it instead.

Yes, poor people tend to have rigid work schedules. If congestion pricing were implemented, employers would have to be more flexible or pay their workers more. Would those jobs that people couldn't afford to take just disappear? We sho

It is not subject to traffic. People don't have infinite money. There is a price at which few enough people are willing to pay that traffic flows freely. That is the price that will be set. People who don't have a choice of when t

With congestion pricing, nothing is subject to traffic. Buses move slowly because they're stuck in traffic and they stop all the time. Congestion pricing eliminates traffic. Ride hailing apps reduce the number of stops. Subways are b

Congestion pricing isn't strong-arming the poor. The poor will just share rides with more people to split the cost. Everyone gets a traffic-free commute. Everyone gets to spend more time with their friends and family. I don't thin

A full van is more space efficient than 12 bikes. I am a cyclist and I think there need to be safe routes to get everywhere in a city. Bikes aren't enough, though. The price doesn't adjust for future optimization. It adjusts for c

Effective ride-hailing services like UberPool and Lyft Line make congestion pricing feasible. Congestion pricing can banish traffic from the face of the planet. Our roads can move a certain number of vehicles per minute at their maximum thr

The difference is that in Clojure, `assoc-in` is effectively a deep copy as well since the data structures are immutable. Most of the complexity involved with nested maps is about the effects of modifying them. In practice, this doesn'

The simplicity culture is what drove me to Python, and the Clojure community's simplicity culture is on a whole other level. It's not just the code and syntax that need to be simple. The abstractions in the program need to be simp

Thanks! Spread the word! There are lots of decentralized applications that need to be built.

It helps to stop thinking about blockchains and smart contracts. Ethereum is a global public computer where programs have their own storage space that can't be modified by anything other than the program itself. You can remove the trus

I think this reverse Yelp you describe is coming soon, partially because I plan on helping to build it. A "trade embargo" can be an effective punishment of last resort for any sort of bad behavior, from crime to a failure to contr
