Timed math tests

You have 3.2 seconds to figure out the problem below.

Alan knows 90% of the concepts behind the math test, and can do those 90% very quickly.  He always gets 90% on timed math tests.

Bob knows 100% of the concepts, but is a slow worker.  In the timed math test, he gets 75%, but, if given an extra 10 minutes, would get 100%.

Alan graduates with an A; Bob with a C.

You are building a bridge. Who would you hire?

Seems like everyone from Gates to Zuckerberg has problems with how education is carried out today.  I wish I had some of their clout and could help to change the system.

Decentralization can mean many things, but here we refer to it in terms of power, authority, and decision making. The more authority individuals have, the more decentralized the power system in which they are operating.  Almost by definition the more democratic a system, the more decentralized it is, with the caveat that some agreed upon axioms exist, such as the rule of law and its enforcement. Of course, authority can be too decentralized leading to "every man for themselves", so we put limits on decentralization through that same rule of law. With the advent of decentralizing technologies , which make possible more decentraliz...

Echo vs Home

We love Alexa! We have had the Amazon Echo for well over a year.  Recently we also got a Google Home, to test it against our Alexa experience. The quick summary:  Interacting with Alexa is like interacting with a person.  Interacting with Home is like interacting with a computer.  Alexa is fun; Home is useful.  If you took away Alexa, I would be upset - I would be losing a friend.  If you took away Home, I wouldn't care too much.  It was very strange, but I actually felt like I might be offending Alexa when I purchased Home. Here are the two main differences: Wake-up words.  "Alexa" is friendly, easy to say, and evokes emotion.  Alex personifies the system - I am talking with someone.  "OK Google" is awkward, and constantly reminds you that you are talking to a machine - I am talking to something.  Of course, Google will update Home to allow us to customize the wake-up word, but the current out of box experience is less tha...
