After learning it costs about $14.00 USD per month to run a bare-bones PowerMac G5 (that’s $170/year!), I have been thinking of how to minimize electricity costs at the abode.

We all love comtemplating the navel, but this clipping is quite good.

As Seen on zen-deshimaru.com

Montpellier, tuesday the 23th of july 2002

Sensei was saying during zazen:

“You should concentrate yourselves under the navel.” Myself, I think we should concentrate ourselves on the navel itself. When we concentrate on the navel itself, we concentrate also on the whole region, above and under. The navel is an intelligence, a consciousness extremely strong. It is the concretization, it is the thinking which concretized itself in reality. All your emotions, all your fears, all your feelings are written there and now in your navel. You can realize the liberation here and now, immediately, with the navel. You can realize absolutely everything you wish with the navel, by thinking with the navel. It is the source of all magic powers. So during zazen, concentrate your attention on the navel, tune your breathing, or tune your navel with your breathing. When you breathe with the abdomen, you navel swims, a bit like a jelly fish. Have you already seen jelly fishes swimming, how beautiful it is? Your navel has that kind of movement opening-contraction.The part of observation during zazen starts from the belly. Sensei said that there were two aspects to the zazen: concentration and observation. If you observe your navel during zazen, every feeling, every emotion will reflect itself directly at the level of the navel.

Hacker Personality Characteristics

§ memes  posted 12 Jan 2004; modified 07 May 2008

From the web site of Eric Raymond [ESR]:

The most obvious common “personality” characteristics of hackers are high intelligence, consuming curiosity, and facility with intellectual abstractions. Also, most hackers are “neophiles”, stimulated by and appreciative of novelty (especially intellectual novelty). Most are also relatively individualistic and anti-conformist.

Although high general intelligence is common among hackers, it is not the sine qua non one might expect. Another trait is probably even more important: the ability to mentally absorb, retain, and reference large amounts of “meaningless” detail, trusting to later experience to give it context and meaning. A person of merely average analytical intelligence who has this trait can become an effective hacker, but a creative genius who lacks it will swiftly find himself outdistanced by people who routinely upload the contents of thick reference manuals into their brains. [During the production of the first book version of this document, for example, I learned most of the rather complex typesetting language TeX over about four working days, mainly by inhaling Knuth’s 477-page manual. My editor’s flabbergasted reaction to this genuinely surprised me, because years of associating with hackers have conditioned me to consider such performances routine and to be expected. -ESR]

Contrary to stereotype, hackers are not usually intellectually narrow; they tend to be interested in any subject that can provide mental stimulation, and can often discourse knowledgeably and even interestingly on any number of obscure subjects - if you can get them to talk at all, as opposed to, say, going back to their hacking.

It is noticeable (and contrary to many outsiders’ expectations) that the better a hacker is at hacking, the more likely he or she is to have outside interests at which he or she is more than merely competent.

Hackers are “control freaks” in a way that has nothing to do with the usual coercive or authoritarian connotations of the term. In the same way that children delight in making model trains go forward and back by moving a switch, hackers love making complicated things like computers do nifty stuff for them. But it has to be their nifty stuff. They don’t like tedium, nondeterminism, or most of the fussy, boring, ill-defined little tasks that go with maintaining a normal existence. Accordingly, they tend to be careful and orderly in their intellectual lives and chaotic elsewhere. Their code will be beautiful, even if their desks are buried in 3 feet of crap.

Hackers are generally only very weakly motivated by conventional rewards such as social approval or money. They tend to be attracted by challenges and excited by interesting toys, and to judge the interest of work or other activities in terms of the challenges offered and the toys they get to play with.

In terms of Myers-Briggs and equivalent psychometric systems, hackerdom appears to concentrate the relatively rare INTJ and INTP types; that is, introverted, intuitive, and thinker types (as opposed to the extroverted-sensate personalities that predominate in the mainstream culture). ENT[JP] types are also concentrated among hackers but are in a minority.
