 Blockchains

Ownership on the Bitcoin blockchain is determined by a pair of cryptographic keys. The first, called the public key, resides in the blockchain for anyone to see. The second is called the private key, and its owner keeps it safe from view. The two keys have a special mathematical relationship that makes them useful for signing digital messages. Here’s how that happens: Helmut takes a message, combines it with his private key, does some calculations, and ends up with a long number. Anyone who...

 The Web Enslaves Us With Convenience

In The Matrix, Neo learns that humanity is enslaved by machines. The populace “lives” in a virtual world, unaware that their body heat is being used as an energy source. I see a sort of low-fi parallel of this in our relationship with Facebook. Every member operates in that “free” forum, largely unaware that they’re powering the thing by relinquishing their user data. This scenario is in stark contrast to what we once hoped the web to be. We imagined it as a means of liberating peo...

 We Compile What We Read in the Context of When We Read It

Reading and experience train your model of the world. And even if you forget the experience or what you read, its effect on your model of the world persists. Your mind is like a compiled program you've lost the source of. It works, but you don't know why. [...] ...reading and experience are usually "compiled" at the time they happen, using the state of your brain at that time. The same book would get compiled differently at different points in your life. Which means it is very much worth re...

 Algorithms are Subjective/Creative Things

he algorithm may be the essence of computer science – but it’s not precisely a scientific concept. An algorithm is a system, like plumbing or a military chain of command. It takes knowhow, calculation and creativity to make a system work properly. But some systems, like some armies, are much more reliable than others. A system is a human artefact, not a mathematical truism. The origins of the algorithm are unmistakably human, but human fallibility isn’t a quality that we associate with ...

 The Great Man Theory Promotes Misunderstanding of History

The Great Man theory is the notion that behind every great innovation is a single individual -- usually a man. It attempts to write a simple story about every innovation. But Ford didn't invent the automobile, Edison didn't invent the light bulb, and the Wright brothers didn't invent the airplane. The simple story strips away all the other people with whom that person worked, both before and afterwards, and their critical contributions to the innovation process. It also perpetuates the notion...

 The Role of the Educator In Regards to the Future

The world is changing -- it is getting both smaller and bigger at the same time. Our world shrinks as technologies now allow us to communicate both synchronously and asynchronously with peers around the world. Conversely, the explosion of information now available to us expands our view of the world. As a result of the ability to communicate globally and the information explosion, education must change. Most educators might not want to change, but the change is coming -- it is a matter of whe...

 Engineering New Ways to Think About Things

One cluster looks, for example, for new ways of representing and understanding complex systems. A second cluster aims for more access to knowledge by undoing contemporary media’s restrictions (such as the restriction of the screen, which produces, with its peek-a-boo access to complexity, impenetrable forms of knowledge such as the trillions of lines of code, written on screens and then stared at on screens). A third cluster explores new forms of representing time, and a fourth one more eff...

 Recursive Cybernetic Design

In 1962, a few years before Alan Kay started his career, Engelbart set the program for his own U.S. Air Force–funded research group at the Stanford Research Institute (Bardini 2000:1-32), aiming for nothing less than to re-engineer the “HLAM-T,” the “Human using Language, Artifacts, Methodology, in which he is Trained” (Engelbart 1962:9). This HLAM-T was always a cyborg, and as such it can be engaged in a continuous process of “augmenting human intellect.” According to Engelbart...

 The problem with testing for abstraction

...students learn by doing. Testing for abstraction on an exam can’t be the only way we’re evaluating student learning. If I had taken an exam on leadership in World of Warcraft, I would have likely failed, because the way I was engaged was through the practice of performing the leadership, not by talking or quizzing on it. Thought leader within the game-based learning movement, James Paul Gee, refers to this type of learning as “Situated and Embodied Learning,” where the learning is ...
