When you use Alexa to find a table at your favorite restaurant, you and she are both aware and responsive as you discuss eating, even though Alexa has never felt the texture of a crunchy apple against her teeth, the effervescent prickles of sparkling water against her tongue, or the gooey pull of peanut butter against…
Excessive positivity also expresses itself as an excess of stimuli, information, and impulses. It radically changes the structure and economy of attention. Perception becomes fragmented and scattered. Moreover, the mounting burden of work makes it necessary to adopt particular dispositions toward time and attention…
The computer was suddenly revealed as palimpsest. The machine that is everywhere hailed as the very incarnation of the new had revealed itself to be not so new after all, but a series of skins, layer on layer, winding around the messy, evolving idea of the computing machine. Under Windows was DOS; under DOS, BASIC…
...libraries are a natural example of a memory hierarchy when used in concert with our own desk space. In fact, libraries in themselves, with their various sections and storage facilities, are a great example of a memory hierarchy with multiple levels. As a consequence, they face all sorts of caching problems. They…
At Livermore, a legendary senior weapons designer is about to retire. At the Spring 2005 MIT workshop, his colleagues discuss this retirement and refer to it as “a blow.” They are anxious about more than the loss of one man’s ability to make individual scientific contributions. He has irreplaceable knowledge about the…
When I was a graduate student, if you were going to convert some data or something like that, you would write the FORTRAN code to convert the data yourself. That’s how you would do it. Now there are these programs. There are these windows and you click. I .nd with my students all the time, they don’t know why…
Kay: Go to a blog, go to any Wiki, and find one that's WYSIWYG like Microsoft Word is. Word was done in 1984. HyperCard was 1989. Find me Web pages that are even as good as HyperCard. The Web was done after that, but it was done by people who had no imagination. They were just trying to satisfy an immediate need…
虛實: 夫兵形象水，水之形，避高而趨下：兵之形，避實而擊虛；水因地而制流，兵因敵而制勝。故兵無常勢，水無常形；能因敵變化而取勝，謂之神。故五行無常勝，四時無常位，日有短長，月有死生。 Weak Points and Strong:...: Military tactics are like unto water; for water in its natural course runs away from high places and hastens downwards. So in war, the way is to avoid what is strong and to strike at what is weak…
Recently, I have been struck by the research concerning mindfulness. Just allowing our children time at the beginning of the day to meditate seems to do wonders in focusing them for the day. Even something as simple as repeating a phrase seems to alter our brainwaves and wire us for success. So I posit, after all we…
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…
“Lin Lin is too smart. To work in fundamental theory, one must be stupid.” In later years, I began to understand his words more and more. Lin, you truly are too smart. Even a few years ago, you could feel the political winds shifting in academia and prepared yourself. For example, when you taught, you changed the…
Being a good Dungeon Master involves a lot more than knowing the rules. It calls for quick wit, theatrical flair, and a good sense of dramatic timing—among other things. Most of us can claim these attributes to some degree, but there's always room for improvement. Fortunately, skills like these can be learned and…

To end on a more cheerful note, I think I have found a fallacy or two in some of the more spectacular arguments used by the Insect Age enthusiasts when they are hardest pressed. For one thing, the fact that insects as a class are 300,000,000 years old, if it is a fact, while we have been here only about 1,000,000…
I cover my ears when Tawaddud shouts the Name. By now I have a fairly good idea about how it works. Extreme fractal compression of some kind, a self-referential loop inside a story, forcing the target brain to iterate it all over again, bootstrapping a new mind inside it into existence. How it is possible, I do not…
Synchronized with the northern winter solstice, the terran computational calendar began roughly*10 days before the UNIX Epoch. Each year is composed of 13 identical 28-day months, followed by a 'minimonth' that houses leap days (one most years and two every 4th but not 128th year) and leap seconds (issued by the IERS…
When you were in college, did you ever meet bright kids who graduated top of their class in high-school and then floundered freshman year in college because they had never learned how to study? It's a common trap. A friend of mine calls it "the curse of the gifted" -- a tendency to lean on your native ability too…
If you build a machine that makes connections between everything, accumulates all the data in the world, and you then harness all available minds to collectively teach it where the meaningful connections and meaningful data are (Who is searching Whom?) while implementing deceptively simple algorithms that reinforce…
C is a big language with a lot of features, and it’s easy to get lost in how fun it is. But you can’t really appreciate a feature without knowing what it’s like to do without. So do things with limited resources. Make a binary adder using falling dominoes. Make a functional digital clock with neon bulbs, resistors…
Production of speech is seen as a pure motor act, involving muscles and the neurons controlling them, while perception of speech is seen as purely sensory, involving the ear and the auditory pathway. This parcellation of the systems appear intuitive and clear, but recent studies [beginning with Taine 1870!]…
