CREW stands for Continuous Review Evaluation and Weeding, and the manual uses “crew” as a transitive verb, so one can talk about a library’s “crewing” its collection. It means weeding but doesn’t sound so harsh. At the heart of the CREW method is a formula consisting of three factors—the number of years since the last…
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…
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…
An understanding of what the Internet is. "I found it on the Internet" is not an accurate statement. You found it on a computer connected to the World Wide Web. Ways to formulate queries. Typing "childhood obesity" into a search engine is not the best way to discover what health problems are associated with being…
In 1986, John Holloszy of Washington University immersed his lab rats in shallow, cool water for four hours each day. They burned so many extra calories that they ate half again as much as control rats, but weighed less. The cold rats lived 10% longer, on average. Holloszy framed his report on this experiment not as a…
Neocortical neurons have thousands of excitatory synapses. It is a mystery how neurons integrate the input from so many synapses and what kind of large-scale network behavior this enables. It has been previously proposed that non-linear properties of dendrites enable neurons to recognize multiple patterns. In this…
IA, or Intelligence Augmentation, is all about empowering humans with tools that make them more capable and more intelligent, while traditional AI has been about removing humans fully from the loop. The traditional torch bearer for IA is Douglas Engelbart, who laid the seeds for much of the Personal Computer…
Begin with a story or explanation of the term. Modeling how you use the word in your life or in conversation may be helpful to students. Have students put information into their own words. This process, which I call “recoding,” is necessary to make sure students understand the word. This is a vital step in the memory…
Haldane did not foresee the computer, the most potent agent of social change during the last fifty years. He expected his Daedalus, destroyer of gods and of men, to be a biologist. Instead, the Daedalus of this century turned out to be John von Neumann, the mathematician who consciously pushed mankind into the era of…
“In One Dimensions, did not a moving Point produce a Line with two terminal points? In two Dimensions, did not a moving Line produce a Square wit four terminal points? In Three Dimensions, did not a moving Square produce - did not the eyes of mine behold it - that blessed being, a Cube, with eight terminal points? And…
Thus, your knowledge is represented in various forms that are stored in different regions of the brain, to be used by different processes. What are those representations like? In the brain, we do not yet know. However, in the field of Artificial Intelligence, researchers have found several useful ways to represent…
My vision of life is that everything extends from replicators, which are in practice DNA molecules on this planet. The replicators reach out into the world to influence their own probability of being passed on. Mostly they don't reach further than the individual body in which they sit, but that's a matter of practice…
For some reason Apple is still considered the liberal/counter-cultural choice but if you think about every dystopian novel/movie and then I said “there’s going to be a company, the world’s largest company (or thereabouts), they’re going to sell one product (basically - the difference between an…
We consider a strategy of straightforward duplication of the activity, and look at the numbers of some of the components. The human brain has up to one hundred billion (10^11) neurons and between one hundred trillion (10^14) and one quadrillion (10^15) synapses. But we have reached a point where for purposes of data…
If you don’t know how to fix it, please stop breaking it. You grown ups say you love us. Please, take action. And for me,it is absolutely my responsibility to do whatever it takes to protect my child. When the haze gets serious, there is at least one thing we can do. That is to protect yourself and your loved ones…
‘Duh huh! That’s putting it mildly!’ Zinda purses her lips. ‘There are two problems, really. The first is that we can’t solve any hard problems. Not really. Anything that’s NP-complete. The Travelling Salesman. Pac-Man. They are all the same. All too hard. Even if we had a computer the size of the Universe! It drives…
"We have a phenomenon very like that in industry," Galiagante said when she was done. "It's called green thumb syndrome. It sometimes occurs when a new plant establishes a complicated but known procedure for the first time. Your people set it up perfectly but nothing happens. The oxides won't reduce, the catalysts…
DAVIES: You know, and you say many times in the book that you're more a writer than a performer. CLEESE: It's always hard for people to believe that because of course, anytime they've seen me it's because I've been performing. You know, they don't go to their televisions and switch them on and see me sitting at home…
he most common example used is the hives of social insects, where all individuals work for the common good with little regard for themselves. Although it has been argued that hives lack collective minds (Nicholls 1982) it should be noted that all such species communicate with chemical signals, and at least in the case…
What I really, truly miss is the physical trail that typing usually gives you. Typing on an actual typewriter on paper is only a softer version of chiseling words into stone.
