 The Educational Ethics of Hackers

A mantra among hackers is “Less Yack, More Hack.” The hacker is a bricoleur, involved in “making do,” and, in doing so, recovering a non-alienated self. Yet being a “hacker” is more than mere individual inventiveness. It involves a larger set of ideals. A hacker should always practice freedom of expression, respect privacy, catalyze self-initiative, be enthusiastic about involvements, have a passionate attitude toward work, do work that is truly enjoyed, exercise creativity, and p...

 Hacking is Playful

Also central to the Hacker Ethic is playfulness. At a 2006 O’Reilly Emerging Technology Conference, Matt Webb and Ben Cerveny wrote, “Hacking is a playful act. In a primal sense, play is the investigation and experimentation with borders and combinations” (O’Reilly Emerging Technology Conference, website). Despite early, highly structured approaches to computing in mainframe laboratories in the mid-twentieth century, a computing culture of iterative experimental hacking has evolved th...

 Six Components of Teaching Reading

Component 1: Reading Aloud Reading aloud can be done as a full class activity, in small groups, or on a one-to-one basis. It involves an adult reading a piece of text or a book out loud to students. However it is done, it is a teacher-directed activity that requires student participation, as Debra Morrison indicates in Read Aloud and Movement, an ASCD video-based professional development program. Debra reads a book to her students about a cricket who wants to be a butterfly. As she reads, sh...

 All the Ways of Intuiting 1729

Stanislas Dehaene brings up the Ramanujan-G.H.Hardy anecdote concerning the number 1729. The idea of running through the cubes of all integers from 1 to 12 in order to arrive at Ramanujan's spontaneous recognition of 1729 as the smallest positive integer that can be written in two distinct ways as the sum of two integral cubes is inappropriate and obscures the workings of the naive mathematical mind. To be sure, a computer-mind could come up with that list at a wink. But what would induce it ...

 "Dark Matter" and "Dark Energy" are Terms That Hide Ignor...

We can measure the influence of this thing we call dark energy, which is forcing an acceleration of the expanding universe. We don't know what that is, we don't know anything about it, other than what it's doing to the universe. Then 85 percent of the gravity of the universe has a point of origin about which we know nothing. We account for all the matter and energy that we're familiar with, measure up how much gravity it should have — it's about one-sixth of the gravity that's actually ope...

 "Holistic" is a Word That Hides Our Ignorance

We're often told that certain wholes are more than the sum of their parts. We hear this expressed with reverent words like holistic and gestalt, whose academic tones suggest that they refer to clear and definite ideas. But I suspect the actual function of such terms is to anesthetize a sense of ignorance. We say gestalt when things combine to act in ways we can't explain, holistic when we're caught off guard by unexpected happenings and realize we understand less than we thought we did.

 "Colic" Means "I don't know why your baby is crying"

The strict medical definition of colic is a condition of a healthy baby in which it shows periods of intense, unexplained fussing/crying lasting more than 3 hours a day, more than 3 days a week for more than 3 weeks. There’s that word there, unexplained. For years I thought this word “colic” described a phenomenon that was understood and therefore natural. The etymology of the word, pertaining to “disease characterized by severe abdominal pain” in the early 15th century suggests ...

 One in 1,000 to 500 Chance of Cancer from Childhood CT Scan

The first study to assess directly the risk of cancer after CT scans in childhood found a clear dose-response relationship for both leukemia and brain tumors: risk increased with increasing cumulative radiation dose. For a cumulative dose of between 50 and 60 milligray or mGy (mGy is a unit of estimated absorbed dose of ionizing radiation) to the head, the investigators reported a threefold increase in the risk of brain tumors; the same dose to bone marrow (the part of the body responsible fo...
