You only need to learn one oo procedure based language. All others are just a book exercise.

The problem with that is most people think because they can program in that language they understand the paradigm.

There are tons of c++ and c# programmers out there who think object orientation is only about turning UI controls into objects. All other code is more of a mix of bad OO and imperative programming.

I would revise your original statement to you only need to learn one oo language well. Same for functional languages. You are have to know a language well to understand the paradigm.

I just don't agree with him. Bitcoins have some serious issues. If someone develops a digital currency that addresses those issues and makes them more practical for every day use I support it. If I had to wait for 10 minutes to get my starbucks coffee paid for I'd probably decide to just pay cash. I also wonder how quickly the blockchain would grow if bitcoin became more mainstream. Anonymity is also an issue. I think competition between digital currencies will only make them more practical and robust. That can only be a good thing for digital currencies in the long run. If progress is not made digital currencies will never replace conventional ones.

I think you missed the point of the article. Demand is far easier to manipulate. Cost incentives that match demand to supply will work if you scale the cost dynamically to match the instantaneous capacity of the grid. Turn a factory on full power when the wind is blowing and slow it down when the wind isn't.

Reminds me of running instances on AWS. AT&T has no financial incentive to reduce these surprise charges. Seriously there should be a hard cap that we can set. Sure we are responsible for these charge, but most of the times naive consumers are not aware. Amazon clearly posts the prices of their instances, but it's not uncommon to get a $30,000 bill accidentally due to some developer testing out their application by spinning off instances. You get charged for the whole hour when an instance starts on AWS and things can show up on their accounting system weeks later.

A real time system for monitoring usage should be mandated by law and sufficient warning should be available. A data roaming plan should automatically be applied if it will save you money. Most importantly we should have the ability to set a cap.

We are experiencing system trouble -- do not adjust your terminal.
