So I was damn close to buying that AMD64x2, a loss leader at Circuit City yesterday, but not surprisingly they were out, and although the floor copy was mine at a discount, I'd have to forego any future free Vista upgrade. So I killed the deal. At least Kim and Jimmy found what they were looking for. We also checked Office Depot for post holiday pre Vista discounts.
I'm following Derek's advice, screening lots of candidates -- which includes buying a copy of CPU (Vol 7, Issue 1) to stimulate my lust reflex with glossy pictures (like check out that Asus Striker Extreme mobo on page 67).
In addition to KTU3, I've been submitting specs for the PKL network, however that's a hands-on lab for NGOs and GOs (i.e. public sector) wanting to simulate donor databases, home health monitoring ala CareWheels or whatever. Some of those workstations won't even need hard drives, ala K12LTSP.
Private industry won't get away with just a booth and some dog and pony show. Our simulators will put candidate software and hardware through their paces, so customers will have a "try before you buy" kind of experience. Lots of GNU, Linux, free and open source in this picture. We call it Studio How To, a spin off from my 1997 Project Renaissance initiative.
I envision KTU3 more as a personal productivity tool for just me and my usual back office 4D Solutions brand CP4E (computer programming) and HP4E (more geometrical) curriculum writing, of which I've already published a ton.
Although firewire is included in most candidates I'm screening, I'm not really supposing KTU3 would be a launch pad for the 4D Studios and/or Wanderers curriculum videos. Those'll more likely take advantage of the render farms, per the ToonTown model. KTU3 will allow me to keep previewing our pre-release inventory, as a member of various quality assurance teams.

Anthropology Question (Synergeo 31526)
So here's my puzzle.
You have this recognized elder and chief who gets all these accolades, plus who invents something that makes geometry easier for young people of the tribe, and all without robbing them of anything already on the books.
Then the elder chief dies (1983).
Then all that promising stuff about the whole number volumes and and so on just gets swept under the rug, not shared with the kids, for at least one generation, maybe two (we're still waiting to see), some'd argue three (I'm dating from 1975, but the chief was already old by then).
The question: is this a common pattern in human cultures?
That "invented something," just to be specific, is yet another mandala or "matrix" of interposed polyhedra. We've seen these a lot in both the east and the west.
This one intersects the two tetrahedra, Star of David style, then crosses the resulting cube with its dual, netting Kepler's space-filler rhombic dodecahedron. The respective volumes: 1:3:4:6 as in tetrahedron, cube, octahedron, rhombic dodecahedron.
Now that's not the whole story. If you pack 12 rhombic dodecahedra around the nuclear one, diamond face to diamond face, the 24 outer edges so formed define the rhombic dodecahedron's dual, a cuboctahedron, which weighs in at volume 20.
And finally, the Jitterbug Transformation, a bridge to the world of five-fold rotationally symmetric shapes, per Hargittai & Hargittai.
That's all pretty easy (no?) especially if you see it cartooned.
The volumes, again: A & B = 1/24; MITE = 1/8, Tetrahedron & Coupler = 1; Cube = 3; Octahedron = 4; Rhombic Dodecahedron = 6; Cuboctahedron = 20. Plus the five-folders (where you'll net your 5 and your 2).
We're not talking Einstein or rocket science here. We're talking basic Sesame Street level visualizations involving primitive shapes, with easy links to low order whole numbers and fractions, yet with threads branching everywhichway into interesting, relevant topics, including into purely mathematical ones (phi, fibonacci).
Our collective resistance to sharing this little gem of interlocked concepts, with our nation's pre-college kids, is something I think will go down in the history books, as well as the anthropology and psychology books, as a story worthy of some focussed analysis (and perhaps some gnashing of teeth).

3-frequency cuboctahedral packing
(92 + 42 + 12 + 1 = 147 balls)
Then you have a way to crack the cube into subpieces, or the coupler if you prefer, to get the 24 and/or 8 MITEs (cube and/or coupler), each dissectible into two As and a B, the As left and right handed, the B either left or right handed.(92 + 42 + 12 + 1 = 147 balls)

Personnel Shakeup
"on break"Otherwise, it was another typical day in the neighborhood: long brightly lit hallways, concrete echoing stairwells, windowed and windowless offices, and cafeterias (two of them, a slice of pie both times, getting some on my newly dry cleaned suit jacket -- but it came off easily).
We talked about New Mexico some more, amidst the usual day job SQL chatter re pulling lesion-device pairs for outcomes research purposes (the patients stay anonymous, but devices have serial numbers, and we need to know which work the best -- an empirical question).
Derek is a member of my personnel search committee, and counseled doing a wider search among candidates, and working backwards with a specific end use envisioned (we used to give this same advice in CUE days).
But this isn't a typical upgrade. KTU2 is severely handicapped, yet I think might be destined for greatness as a future Linux box, as the crossed wires are all in the software. But we're not about to wipe this hobbled energy slave clean, without some backwardly compatible KTU3 in the picture.
Regarding the new public school TV shows, we're still exploring the issue of "what tracks?" Pure mathematicians often chafe about how their discipline gets mangled in K-12, and we've historically made them stuff those concerns, because there just weren't enough hours in a day to make "pure math" a reasonable use of Johnny's or Jennifer's time.
But now, with all the unused media capability, plus asynchronous scheduling solutions (for "time shifting" as we say in the industry), we suddenly see room for greenfield development in this area.
Let the purist mathematicians have their own channel or channels why not? What's the harm?
Then the other disciplines, which use math without being math, don't have to worry about Jennifer and Johnny not getting it straight from the horse's mouth as it were.
They (the other channelists) will soon feel more free to share their "bent takes," wherein the math comes across as deliberately nonstraight, will not have to take so much guff for hogging the limelight.
The more puritanical straight shooters, the "tell it like it really is" crowd, will finally have a place in the sun, an unobstructed curriculum track, complete with with its own advancement criteria, and with a target demographic reaching all the way back to the primary school level.
Such Math Channel programming might seamlessly blend with the more normally twisted fare, with students free to switch tracks more or less at will. This is not a "one size fits all" solution, is instead a strategy for offering more choices.
Let's take quality of life enhancing advantage of all these new tools, why not? And open source will play a huge role in getting these goods delivered (already is playing a huge role).

A Random Walk in the IVM Forest
:: Mad Magazine, 01.2007 ::
Wanderers this morning was about Phase Rule stuff: thin metal strip sensors, able to detect toxins in mere parts per illion (million, billion...), perhaps released in a pressure or temperature change.I asked about mercury vapor as a hazard in mining, after making some cracks about Newton thereon (not the only alchemist so imbued, plus girls sipped arsenic to make their veins glow blue).
That set our geochemist (the gent to my left, a Thirster) into a very detailed discussion of the mercury vapor problem, well known to gold miners. Better if the vapor could bubble up in some acidic pool and just cake at the bottom. There's actually an aftermarket for that sort of thing.
Our guest XX this morning (the rest of us XYs), was a star athlete in her last chapter, is now shifting into computers, starting with knowing a lot about version control.
I launched into a somewhat long-winded tale of Free Geek trying to bond with local area nonprofits, under the auspices of a forward-thinking MMT (Fred Meyer's foundation).
This first tentative knotting proved a highly technical undertaking, involving a Mozilla, Perl, and Postgres stack. Naked Ape made the Perl OOish. I siphoned data from Access to Postgres, using a monster data transformer script mostly written by others (but I helped a little).
This was around the time of my wife's first diagnosis, and I needed to bow out of some of my roles.
Anyway, the nonprofits (NGOs, plus a lot of GOs, per GOSCON) still get kinda panicy around so much mumbo jumbo in computer world, which we geeks like to spew forth in firehose quantities, but get slapped down for doing.
A culture clash of some sort. We'll work it out. Somehow. Someway.
The future's gotta happen, i.e. "What, Me Worry?"™
I did manage to crank out a little talk on the group properties of the totatives of N, field propeties if N prime. Our athletic XX version controller had expressed some interest in the subject during intros, and although I'm no expert, I've been rooting for Gnu Math @ Math Forum, so have such material on tap when cued.
"Women rule in Computer Science" is my motto, related to my going gaga for Athena, an Ice Queen (IQ) of sorts: coolheaded, logical, serene, yet intuitive. A positive synergy, worth putting on a pedestal.
Trevor, newly armed with NYT access, was searching on you know who, and came up with this 1955 story about a mock liberation of Philadelphia in a simulated atomic war, with Russian brass invited to attend and attending. I forget what was Bucky's role in all this. In another story, he's serving on the board of a homeless shelter for single male vets, having recently purchased Shelter magazine.

Cracker Dog
:: cracker dog ::I'm pretty sure the cracker dog (foreground) in the above picture is from Germany.
My grandparents on my mother's side favored a popular option for retired people back then: fun in the sun in a prefab or mobile home, with money saved from a big mortgage on trips to a then still America-friendly post-WWII Europe. They came home with all kinds of cuckoo clocks, walking sticks, stories, and slides of Kodak moments.
That was a bravely positive working class futurism I think, to reconnect with war torn Europe as adventuresome ocean liner passengers, eager to mix with those Marshall Plan dollars, to help the roses rise, while meanwhile, on the home front, pioneering a somewhat spacey, new and replicable lifestyle, around shuffleboard, square dancing, golf carts and tourism.
[ True, no air-deliverable Dymaxion Dwelling Machines materialized, like Bucky wanted, seein' as all the good helicopters were needed for service in Vietnam. ]
Not a bad outcome for a career linotype operator plus spouse, empty nesters on quasi-fixed incomes. Has any subsequent generation proved bolder or more successful, at making its dreams for a civilian utopia come true?

A Window on Physics
Dr. Bob Fuller was through again, this final day of 2006. We had coffee at Peet's (hazelnut latte for him, eggnog latte for me, and thanks Bob, for buyin' -- on me next time).
Since last May, he's completed that article for CISE (see Vol 8, Issue 5) regarding how computing is figuring into college physics classes, a topic I gleaned info on at New Mexico Tech as well (Dr. Sonnenfeld let me study his final for his strenuous Matlab in physics course).
Bob briefly reviewed the history of the Calculus Reform movement for me (a lot about Harvard), part of which he saw from the vantage point of West Point academy, where civilians had been hired to implement said changes.
Students would now know how to look at calculus through four windows: graphical, textual, analytical and numerical (think of the four windows of a tetrahedron).
What helped big time at West Point was the discipline of rank: the department head would be a colonel, the classroom teachers captains. So if the order from on high was to "reform calculus," then by golly that's what happened, provided the mission was well planned and well executed (and at West Point, you'd expect higher odds of that happening).
For my part, I relayed more information regarding my summit in April, with The Shuttleworth Foundation, on the subject of revamping analytical thinking courses using peer teaching models, for ages 8-18, in the RSA.
Again, although these various "reform" movements (think of them as well established voices of dissent, counter-cultures) don't tend to dramatically take over all that often, they do remain simmering sources of back burner thinking, thereby tending to influence even front burner offerings over time.
For example, in this case, the mainliner calculus texts which to this day dominate the market, are more "reformed" than they used to be.
Early Calc Reform mottos: "lean and mean"; "a pump not a filter."
Tara got one of those Lego Minstorms™ products for Christmas, so now I'm off to the store in search of ziplock bags, given the myriad little pieces (over 500) that come in the kit. She and Brenna want to build the humanoid on the box, more fun than the little demo guy we built together on Christmas.
Later, Dawn and I watched the retrospective on Ed Bradley's career on 60 Minutes.

Lunch Near Pauling House
:: pauling house ::Both times, being too obvious with the ears nearly cost Bond his job. Both times, he was able to compensate, thanks to earlier training.
The tan leather jacket has gone missing, while another, black, Tara's size, came and went. Dawn's (also black) is still in good condition, hangs in our closet. I briefly had fantasies of the three of us (Carol and Julie have returned to LA), looking like the Biker Family for our holiday letter. Not this year.
Tonight, we'll be celebrating Mike Hagmeier's birthday again, per tradition. He's been more active in Wanderers lately, but during times I've been absent, in either Florida, New Mexico or closer to Canada.
This afternoon, we're celebrating Greg's and Yulia's getting together last October, in a matrimonial manner. Greg mostly lives in Russia these days, is the son of Chris & Larry.
The math talk has been interesting of late (to me at least), delving both into theoretical stuff around limits, a calculus topic, and into an application of casino math, as applied to anti-racism.

Later:
The TSA guy said he liked my shirt (above), as he patted me down. Homeland Security says we're on orange today.
The Indian Pueblo Culture Center on 12th, just off I-40, is a peaceful place, as I commented in the guest book. A proud dad of the Laguna Pueblo introduced his family of dancers (2 older boys, a 14 year old girl, a younger girl in training), then sang and drummed, while his kids demonstrated growing mastery of ancient ways.

Secrecy and Democracy
Even back in Ronald Reagan's day it was always a question of how to promote transparency in government while keeping vital secrets from falling into the wrong hands.
This is the perennial question for a democracy, presuming enemies exist, which is pretty much a given, as it's a difficult form of self government to practice, and many want an easier way, especially where selfish ends are concerned.
As geek culture gets more experience, with its new tools and ethical codes, some of the same questions arise in new forms.
I asked this of Richard Stallman when he came to Portland: what if there're groups you think unworthy of your free source code? Shouldn't we geeks have the right to not empower those who would subjugate us?
I suppose a good answer would be that this is just a cost of doing business, and in the long run, those who collaborate will win out over the more isolated and necessarily secretive.
These thoughts continue my ramblings on geeks as role model math teachers. Keeping our mathematics strong, free and open is part of what gives our democracy a backbone. I'm also continuing my Katrina Math thread.

Casino Royale (movie review)
This was Tara's first Bond movie, and she worried at first she'd need more of the back story. I whispered the basics, about the Brits and their double-oh mythology -- not much to know.
I actually read some of the Ian Flemming books in my youth, and Casino Royale rings a bell as one of his first and mine (as a reader). Sure enough, Bond is just earning his wings in this movie, trying to impress his MI6 boss. Yet the timeline starts post 911, somewhat subverting the earlier films. Batman Begins seems kinder to its less proficient sequels.
The club (as in the card suit) does look a bit like a Mandelbrot Set -- I hadn't made that connection. I caught the global matrix motif (red hexagons) as Bond zoomed in on the villain's powerboat's location in Nassau, using M's computer.
Tara'd been asking about Venice. That's the fun of Bond movies, getting to see the backdrops, and in a mode that'd blow the average tourist budget in a heartbeat. Interesting touch to have a defibrillator in the car (is Bond finally showing his age?).
The Swiss bankers come off as a bit goofy, but still handle the money securely. Lots of brand placements per usual, though I can't remember any beyond the Sony Vaio at this point.

Winter in Santa Fe
:: hotel room view ::Further north on I-25, we got out ahead of the snow, back to 75 mph driving conditions. The storm caught up with us after we'd already checked in, making this place even more picturesque than usual.
Now we're just hangin' out (no, the wireless ain't free -- must key to MAC address because the ISP didn't hassle me this morning). I've got saline and TPN goin' on Dawn's two lumens (PIC line), while Tara blisses out on Cartoon Network.
Last night we watched a Harry Potter on HBO (plus I used up my free 60 minutes playing Luxor 2), but the guest in the adjacent room had a TV remote keyed to the same frequency and kept ordering porn films, interrupting our viewing -- a good metaphor for something or other. Anyway, room service fixed the problem (rekeyed our TV and remote).
I'd scrounged a fresh baked pizza from an upscale joint nearby (given the snow, I was the only other customer). But I forgot that "four cheese" (actually "quattro formaggi") in upscale-speak means just the cheeses (no tomato base), probably one of them goat, meaning Tara couldn't eat it (she tried), meaning I had to snarf most of it myself (I gave her the crusts). We also raided the minibar. Cheapskate that I am, I'm hoping to replace at least the beers from a local supermarket.
Wanderers called me from their morning meeting and passed the cell phone around. Jon warned me to steer clear of bad art in this most galleries per capita town (even more than Catalina?). A lot of it's pretty good though -- and well outside of my price range.

Blogging from Albuquerque
One more interesting number is that about 13 million people have created blogs, but only 39 million say they read someone else's blog. Crunch the numbers. That's an average of three readers per blog.Math point: that average holds only if those 39 million read an average of just one blog each. My experience of the blogosphere is it's a place to go digging i.e. there're lots of blogs to explore, including Eleanor Rigby's.
Census: We're Fat, Lonely, Smelly (CBS News, 2006.12.15)
Yes, a blog may be like a personal diary for some, but they have other uses as well.
Given the bookkeeping connotations of "journaling" (the Quaker term for blogging) I tend to think of mine as recording transactions, the movements of money or mojo, whatever bull. I read others' blogs for such clues as well.
Bucky Fuller developed his Chronofile as a means for tracking his experiments with 'Guinea Pig B' i.e. himself.
Also in the news: a suspension of executions by lethal injection in Florida, because the procedure wasn't working properly -- shades of Mr. Death.

Wanderers 2006.12.12
:: invading "biships" ::(click for larger view)
Homer, a native of Silverton, taught himself editorial cartooning in part by studying the works of his hero, Thomas Nast. To Nast we owe much contemporary political iconography, including those familiar Democratic and Republican icons, the donkey and elephant respectively.
Nast also developed the Tammany Tiger, which may linger in the affected "richie rich" mannerisms of some subsequent toon tigers, including Disney's perhaps. The above cartoon is one of Nast's, in support of public schooling.
Gus has done a lot of independent scholarship plus self-published a collection of Homer's drawings, interleaved with the back stories required for their full appreciation.
Lynne Taylor was late to the meeting, a slap-forehead missed opportunity to quickly review the same slides we'd just seen (often a good exercise). Wanderer Shomar joined us even later.

Katrina's Aftermath
I've long had a Google query checking in the background for news items mentioning "geodesic" and "mosque" in the same story. Usually, it comes up empty handed, but today it provided a link to an interesting article in ReasonOnline, from which I'll supply this excerpt:
Still, what the article chronicles, people taking responsibility, getting the job done, gives me hope. The keyword "mosque" is in connection with Common Ground, a focal NGO in this story, and which got started in one in Algiers, a neighborhood of New Orleans.

Dwelling Machine Prototypes
In addition to Common Ground, secular organizations such as Emergency Communities, the People’s Hurricane Relief Fund, and Four Directions have joined a multitude of small church groups in the region to provide services where government and big aid organizations fell short. When necessary, they simply ignored the authorities’ wrongheaded decisions: pushing supplies through closed checkpoints, setting up in unapproved areas, breaking the rules when it made more sense than following them.Their organizers, as well as their volunteers, have little experience with relief work. They live in tents or sleep on cots in repurposed churches and community centers. Volunteers run the gamut from hippie dropouts to middle-class students on spring break, and the outposts they’ve built are filled with things you’d never expect to see anywhere near a relief effort: free acupuncture, vegetarian cooking, cross-dressing volunteers, a giant geodesic dome. Despite their inexperience and occasional outlandishness, they are organizing and delivering some of the most effective relief work in the area. [Italics mine]
What's especially telling, in light of my angle on things, is this sense of surprise at seeing a "giant geodesic dome" in any way associated with any relief effort, and in December of 2006 no less -- a measure of our degraded IQ as a culture by some accounts, including mine.
Still, what the article chronicles, people taking responsibility, getting the job done, gives me hope. The keyword "mosque" is in connection with Common Ground, a focal NGO in this story, and which got started in one in Algiers, a neighborhood of New Orleans.

More American Heritage
Many older generation North Americans of the English speaking variety have this expression "What in the Sam Hill?" meaning they've never seen it before, have no ready explanation (the question usually comes with a skeptical edge to it).
What fewer probably realize is Sam Hill was a neighbor in these parts, alias Prince of Castle Nowhere, which castle he constructed along the Columbia Gorge not far from his lifesize model of Stonehenge, in turn close to his tomb.
Maryhill Castle, now a museum, includes a treasured Rodin collection -- that's the guy who did The Thinker -- plus an admirably large collection of chess sets.
Back in the day, when I was still living in Rome, my friend Seth Tuska would sometimes dramatically assume a standing version of The Thinker's pose when questioned about something -- an endearing mannerism I thought. Both Seth and Muqtada al-Sadr remind me of John Belushi in some twisted way (great thinkers all). But then, I'm the guy who linked Rush Limbaugh to Barney.

Mingling Traditions
I spent much of the morning chiseling away at my Wittgenstein Bridge twixt Fuller's philo and an already crowded "chat room," hoping to recruit a few more philosophers over the C.P. Snow Chasm to the engineering and mathematics side, maybe to help us further improve the curriculum over here.
This evening: a celebration of Empiricism at Winterhaven, the annual science fair, with just about every student showing off the results of an investigation, guided by an hypothesis, with a description of procedure, conclusions, preferably numerical data, visualizations (graphs), a photo or two. Lots of judges. Lots of adult scrutiny and peer review.
Tara's entry focused on falling geometric shapes, each with 100 unit squares of surface area (on each side). Which hit the ground fastest? Sounds trivial and pointless (I grumbled a bit) but that's missing the point (I now realize): it's about the discipline of doing, thinking it through, planning and executing, and around a not knowing that you're seeking to get to know. There's humility in it, and a sense of dedication.
I helped Tara just a little this year around finding the edge lengths of a pentagon and pentagram, both 100 squares on each side, like the other shapes (square, circle, triangle, rhombus). I was lazy and relied on Google for a clue. Last year her award winning experiment involved hot oil, I helped more, and yet we almost had a disaster.
I respect Winterhaven, one of Portland's public's, quite a lot, not just its computer science, which is cutting edge and experimental.
Tara is definitely maturing quickly. She's found at least two post-Aibo robot dogs in Korea, one shown in a video clip, the other an artist's conception. I find it too random an interface, this idea of flipping up a lid and reading email on your robopet. Would I watch a movie on my robocat, or maybe unscrew its head and use the body as a wall projector? Tara thinks it's the future. Anyway, we're still in the early phases, when all things seem possible, worth testing a bit.
Then, after a quick stop at Burgerville, we headed over to the Scottish Rite Center, where Revelers were staging a slice of life from a 1600s era piece of what today we call France, in turn imitating inherited traditions, and filtered through today's contemporary American culture (whatever that means right?). Lots of King Arthur type stuff, little psychological skits around dragons, knights, and pretty women.
It's a franchise of sorts, with Revelers in several cities. The program was ambitious, with some 40+ musical numbers, many including audience participation, a huge cast, many children, some stage effects, a dog, lots of interesting dancing. We all sang Dona Nobis Pacem (Latin for "give us peace") which I already knew from our Quaker hymnal (we sang it in Rome a lot when I was growing up, when meeting in private homes -- Phil and Winnie's, Li and Andy Braid's, our place...). Twelve Days of Christmas -- yeah, I knew that one too (of course).
Much of the singing was in French, which I've mostly forgotten, was never much good at (all the Romance languages collided in my head, turning to Bose-Einstein condensate).
Dawn says these Revelers rotate through different ethnicities. She's wanted to see them in action for some time, is making a point of catching these things that she's missed, always wondered about. She missed Festival of Trees though. Another good reason to stick around for another round.
I'd never heard of these Revelers people, nor ever set foot in this Rite Center (Portland Valley's), so the whole evening was quite an eye-opener for me. The audience, and cast, consisted entirely of people I didn't recognize, with the exception of my immediate nuclear family.
They say Portland is a small city, but it's not that small.
I treat Fuller as a post linguistic turn philosopher instead of pre, which most people never thought of doing. Like (a) they didn't think he was a philosopher in the first place and (b) they didn't think his 'deliberately remote namespace' idea would fit in so easily with the language games vista. [ Synergeo 31040 ]We'd also like more media people, many of whom are likewise philosophical or psychological in outlook, people with well developed aesthetic sensibilities (whatever that means right?). You needn't come by any bridge. Boats, tunnels, whatever. Plus this traffic is bidirectional -- at least C. P. Snow thought he could detect some healing, according to Bucky, who apparently kept up with him, and with the late H.S.M. Coxeter (it's an unwanted divide, damaging to our culture).
This evening: a celebration of Empiricism at Winterhaven, the annual science fair, with just about every student showing off the results of an investigation, guided by an hypothesis, with a description of procedure, conclusions, preferably numerical data, visualizations (graphs), a photo or two. Lots of judges. Lots of adult scrutiny and peer review.
Tara's entry focused on falling geometric shapes, each with 100 unit squares of surface area (on each side). Which hit the ground fastest? Sounds trivial and pointless (I grumbled a bit) but that's missing the point (I now realize): it's about the discipline of doing, thinking it through, planning and executing, and around a not knowing that you're seeking to get to know. There's humility in it, and a sense of dedication.

Newflash: Lights On in ToonTown
Today's Oregonian, Business front pageBefore I give notice and return the key, we could brainstorm keeping this as a branch PKL office, provided the rumors are true. I'm open to advice from readers; send HQS a gmail if you like, take some IQ tests (just kidding (not! (see Borat, like this))). Derek? Trevor? Wanderers is open agenda tomorrow, I'll plan to solicit feedback there as well.
But keep in mind, it's just a very small 2nd floor office (with elevator), utility sink plus electrical (and free wireless, if rumors are true).
I've so far removed everything but David's T-modules, which remain scattered on the floor (not in mint condition). Those all could be yours. Going once, going twice...
And did I mention the neighbors were fun? They were all jammed in the bigger corner office next to mine, sharing Friday Margaritas, when Derek and I showed up in the pickup, as moving gentlemen.
We've started a countdown for New Mexico, still in the high T-minus phase (i.e. lift off still days away).
Mixed Results:
Rumors are true to the extent a free Metro-Fi node, plus premium channel, show up on my list, but right now I'm still depending on the good graces of some neighboring private enterprise. MetroFi wouldn't handshake, or maybe it's not really open for business quite yet.I responded by cell to Nirel's voicemail, reaching her in LaLa Land (LA). She aced almost all my IQ tests, per usual, but only to inform me she'd already acquired a target in Seattle, wasn't gunning for Portland.
I can see from whence that old Portland-Seattle rivalry stems: we lose some of our best California girls to our big sister up north. Anyway, I fed her some shark tale (all true) about how I'd gladly share goat meat with her (we're family) were I to score some, other carnivorous imagery (rather off-putting I would imagine -- actually we're on the same wavelength: coffee shops, as in owning, with rooms to host colloquia, symposia).
Anyway, I'm happy enough just seeing the node, to wanna celebrate. Hence the (open) Foster's Special Bitter on the floor next to me, amidst the Koski T-modules, and a Spicy T.L.C. sandwich (tofu & carrots) by Higher Taste of Portland.
Additional results:
I ran the next logical test, which was to find a location where Metro-Fi's signal was stronger, to see if signal weakness was to blame for my above failure to connect from 8th & SE Main. Empirical result: I'm connected, using free MetroFi, but from Lucky Lab, which already had free Portland Telco, sans the ad banner (and counts as a free premium service therefore, but without as much coverage).
The MetroFi node, with Microsoft's sponsorship, wanted to know my income level, a mandatory field. Seemed kinda intrusive. Like, when Saturday Academy asked my ethnicity, I wrote "mixed Asian Anglo" in the provided "other" blank. That'd have to do, no time for fine tuning. I find these computations difficult to just do on the fly. I also put down I was a CEO (a type of chief) -- not lyin'.

Superman Returns (movie review)
Walter Kaufmann (we overlapped at Princeton) felt semi- compelled to translate Nietzsche's to "overman" given what the Americans had done with "superman" i.e. dressed him up for a career in the comix.
But he probably shoulda kept it, as Thus Spake Zarathustra was a proto comic book of sorts, in terms of its archetypal and colorful imagery, its propensity for parables -- like Narnia, like Manga.
The very word "comic" bespeaks a victory of sorts. And to his lasting credit, Kaufmann found some of Woody Allen's works refreshingly hilarious (me too) i.e. he knew philosophy could be gay at times, serious guy though he was. Smallville includes a tie-back (check what Clark's reading when the klutz drops his books, duh).
Clark is especially goofy in this version, which blatantly satirizes the "mysterious masked man" motif. I mean, the guy is the spitting image of himself, with not so much as Groucho Marx glasses for cover (just an ordinary pair). Yet everyone buys it, because his deliberately deflective demeanor is so "not hot" as an office dweeb (shades of Spider-Man, shades of just about any male superhero, although that Batman Begins guy seems a chick magnet even as Bruce -- but I digress).
The genius of this North American storytelling is its obvious and unsubtle use of raw elements and states of matter as a haptic mirror. Very Synergetics. The phony poser to the throne uses Superman's own crystals against him, and the battle royale is a Phase Rule extravaganza, strongly dramatizing the consequences of disequilibrium, expressed in the foreground as tugs within love triangles with doubled edges, quadrupled if you start juxtaposing Lex and his girlfriend as more shadowings -- a complicated family this, veritably bursting with secrets.
Artificial Intelligence was sadder, though still close to the comic book genre -- looks more at a mother-son relationship, whereas this one's son-father.

NanoTech Talk
Our ISEPP speaker last night, Meyya Meyyappan, was good on the intro: the surface:volume ratio is a function of size and properties change as a shape shrinks to the nanoscale. Four grams of nanotubes have the same surface area as a football field, mas o meno. Nano gold particles melt at a lower temperature than gold bricks.
He didn't mention buckyballs, which I called him on at the dinner (excellent salmon, unfortunately for our guest, a vegetarian).
Clearly tubes have an edge these days, though I'd heard they'd stuffed buckyballs through buckytubes that time. Except now we call 'em nanotubes. So maybe the tubes are so popular because now there's a way to avoid saying "bucky" so often? Just asking.
Anyway why not say nanoballs? We should try that on for size. Nano could be the next turbo. We could have store chains like Nanorama. No, the merchandize wouldn't be invisible to the naked eye. Just because it's nano doesn't mean you can't see it, Meyya was quite clear on this point -- like, there could be buckyballs in your shampoo someday!
[ Geneva airport security did this fast juggling of purses and bags, sleights of hand, such that my mom got confused, didn't realized she'd been parted with her new laptop, the Sony Vaio, 'til Zurich. She has high confidance in the Swiss, thinks she'll see it again. I'm not so sure. ]
Anyway, properties at the nanoscale provide a whole new quantum mechanical ball game, and the goal of engineers is to usefully capitalize on that fact, and in more ways than one.
I sat next to a caustic and witty critic of nano all through dinner. He thinks a lot of pigs at the trough are self-servingly taking credit for work they didn't actually do, piggybacking on unsung heros, attracting funding away from more worthy players.
I told him I liked the talk because one of the slides had two CCP cuboctahedra side by side, of two different frequencies. Those are like icons for me. Not bad, to gain control of the Schnitzer, all those impressionable young minds [rubbing hand noises, maniacal chuckling].
1, 12, 42, 92, 162...
Another guy at our table, one Mr. Owl, expressed admiration for Neal Stephenson's The Diamond Age (a book about nano), while our speaker expressed some trepedation about Prey (the movie version's not out yet). Will paranoias about "gray goo" inconvenience the nano family, the new Beverly Hillbillies on our block?

In a Quandary
:: Hurricane Katrina, Magee MS ::On math-teach we've turned our focus to teacher quality in Illinois, the computer science teachers are threshing about discrete math, while over on Synergeo (#30932) I'm dissing the Clinton administration for the bombing of Belgrade (consistently with my views at the time).
That's pretty much my beat these days, not making toons in ToonTown, which'd be my druthers. So maybe I'll get that promotion? I should have a talk with my boss. Plus I still have my other hats to wear.
Wanderers is hosting a 3rd talk in a series re Sacred Geometry tonight, Stockton and I having delivered the first two. Micheal Sunanda is bussing up from Eugene. He's another character I'd stick in my stable of stars in a heartbeat, had I a stable. Well, I've got these journals at least (my so-called blogs).
Speaking of journals, when is Earlham College ever gonna put George Fox's on line, John Woolman's, in blog format, with proper back dating? Too difficult? Hey, maybe that's not work Earlham ever signed up for! Other takers then? Friends'd benefit by having these earlier Quaker journals on line as blogs, easily linked from today's Quakers' postings.

Journey Home
Enroute back to Portland, we pulled off I-5 at Seattle's Northgate, to find our favorite Math 'n Stuff store on NE Roosevelt Way. The store will be moving soon, though perhaps not far.
In addition to some Christmas gifts, which I'm not going to write about, I invested in a second Cube-It! for myself, a toy of 24 colorful magnetic MITEs i.e. space-filling MInimum TEtrahedra of volume 1/8th in Buckminster Fuller's Synergetics.
Now that I have two of these puzzles, not only can I build the volume 3 cube, but the volume 6 rhombic dodecahedron as well, yay.
We'd hoped to visit the Dead Sea Scrolls at the Seattle Science Center, but the exhibit was sold out until evening, so we ascended the famous Space Needle instead.

Lucky Day
Friend Chris is recovering from a successful surgery. We visited her on our way out of town.
I checked with Dawn's oncology clinic and they had my lost bag with all contents. I'd left it there on Friday, yet had persuaded myself that it'd been stolen.
Tara immediately inherited the Olympus Stylus 500, an early Xmas present. I'll stick with the new Stylus 720.
Plus I finally got to share Bodies with Dawn and Tara in Seattle this evening, having seen it by my lonesome in London in April.
Now we're staying in Tulalip and Stillaguamish country, further north, with good friends.
All in all, a great day. Giving thanks.
Even the traffic wasn't too bad, despite some heavy rain.

Lurching Forward
I enjoyed a satisfying conclusion to Pythonic Mathematics today, that was #7571 - Computer Programming from Chaos to Python. The students had turned raw Python syntax to Vpython gold, including a 3-or-4 frequency tetrahedron, moons around moons, and a mom and her kids did this "look, a real professor" number in the Park Blocks (I had the plastic 4-frequency in tow, attracted attention).
However, these triumphs are somewhat overshadowed by the loss of my OSCON bag and all its contents: iPod, digicam, new Russian geometry book... dried up cashews. Part of the torment is imagining the lucky dude who now has all that, and that's if it really was stolen, which I can't prove (more torment). I recall from some Tibetan Book of the Dead DVD that this is the hardest part: watching your killers play with your stuff. Anyway, maybe it'll turn up, along with Robin, my stolen car.
Back to the classroom: we watched excerpts of a Google Technical Talk, Guido rehearsing before OSCON 2006, talking about Python 3000. Then I shared Store Wars (Cuke versus Darth Tater) and the first few verses of Ramanujan (as many stared into their screens, completing projects). I recommended Python 411 and Dive Into Python (starting with the web version) as possible next sources of information.
As for source code, I looked at Pascal's Triangle (first time through) and Fibonacci generators (second pass -- tie back to triangular and tetrahedral sequences, plus Pascal's). I said something to the effect that these gentlemen needn't have been the first to ever conceive of such language games. So calling 'em is more an honor than a right.
I handed out the closed student evaluation forms, which get sealed and collected at the end of the final class by an SA HQS minion (cute colleague, some new kid on the block), i.e. are pretty much unseen by the instructor. Plus we send home parent forms in case an adult guardian wants to give feedback. Plus I get to fill one out about my students, my experience as the instructor. Plus I handed out signed certificates of completion, properly name embossed, like a credential of some kind.
Several of my students expressed in different ways their wish that ordinary school was more beefy like this, dense-packed with relevant multiplexing, with parents seconding the motion. I always make these "right on" noises, like gee I really empathize. That's why I teach through Saturday Academy, to fight for our Silicon Forest and its values, high standards. I've also been invited onto a curriculum advisory board for Portland Public Schools (PPS).

More Hermeneutics
Originally drafted on Synergeo, an eGroup, and therefore populated with references to other discussants -- Editor.
4D
Cliff is in the vicinity and that always reminds me of our shared interest in outfitting Synergetics with some Mathematica style claptrap (caltrop? -- look it up, Braley-sans-w knows), except in my case it's Pythonic harkening back to APLish (given my personal trajectory), more than Wolframic in its computerized expression [*], but that's not a problem for me if it ain't for Cliffie here.
Other names for the Quadrays namespace might be: Chakovians (after David Chako of Synergetics-L fame); Tetrays (Chako's preferred term); Caltrop Coordinates (vs. Cartesian); Simplicial Coordinates (but minus J.H. Conway's focus on the hypercross and Coxeter.4D) -- and maybe Klingon Coordinates in honor of the other big Conway (Damian).
What we do is shoot four "basis vectors" (pirating from linear algebra) to the corners (1,0,0,0) (0,1,0,0) (0,0,1,0) and (0,0,0,1). To reverse a basis vector is to flip its bits i.e. -(1,0,0,0) = (0,1,1,1) and so on. So we end up not needing negative signs in this canonical representation, though by another convention we might alternatively insist that the sum of the 4-tuples always be zero.
The Cartesians claim having 4 basis vectors is redundant, as they get by with just 3, but then they permit vector reversal to play a role in netting them 7/8ths of their space. Thanks to vector reversal and the three negative "not really" basis vectors, the Cartesians have 3 additional "ghost vectors" doing most of their dirty work i.e. pointing in that 7/8ths negatively tainted space, with only one octant (+++) remaining "positively pure" and therefore directly accessible without all the "bad neighborhood" connotations of a "non-basic" (e.g. +-+) address.
So in point of fact, the Cartesians are using essentially six reference vectors to the corners of a regular octahedron, not just three, whereas in Chakovians we're using just four, and not relying on vector reversal for back-handed access to anything.
3D
The four positive basis rays positively scale and vector-add to address any point in Positive Universe. Negative Universe is through-the-origin inside-outing of the reference tetrahedron. Your application may have no need for this other space, conjoined through (0,0,0,0), but it's there if you need it. Nor does it matter which you call Positive initially, though once you've invested, conversion may be time-consuming (just like both left and right XYZ coordinate systems have their followings).
My Synergetics on the Web @ grunch.net contains a thorough overview of Chakovians (./synergetics/quadrays.html), plus transforms for converting to-from XYZ, 4x4 rotation matrices courtesy of Tom Ace.
We don't insist on using these in public schools, e.g. won't be targeting any school boards for not, but we do bring kids through on field trips from time to time, just to remind 'em that XYZ thinking ain't all its cracked up to be in some circles.
Alternatives exist, some of them smart cookie.

Wanderers 2006.11.14
So tonight it was Barry's turn to induct us into the deep metallurgy of small microprocessors, the ones you program once for some permanent job in a car engine or, in Barry's case, a DC light dimmer.
Boats are wired for DC but don't come with a dimmer switch, usually. Barry's gizmo, a coventure, takes DC into a pulse width modulator, written in software, and matched with code to the interface, in this case either one or two switches, and rather complex behaviors.
A feature of this Motorola HC05 series chip is a ripple counter with some flag bits, such as COP. Unless you "kick the dog" every few cycles, COP'll flip and send a reset; useful for when poorly written code enters an infinite loop or whatever. You don't want simple coding errors to devalue the hardware, or maybe the code makes intelligent use of dog kicking internally. Either way, nice to know that COP is there.
So the boat owner chooses to wire either one or two switches, then meters DC power at tiny calibrations, or full on, though even this max brightness setting includes sleeping, i.e. going to low voltage for short intervals.
Given all the interrupts in this picture, 109 cycles a second mas o meno, with 256 intervals within each of those, there's lots of pushing registers to stack, running off someplace, coming back and popping the stack. Nesting subroutines is a source of subtle errors and stack overflows so Barry's code stays pretty flat. He's pretty much self taught, and being a smart guy, he made sure he did a good job of teaching it.
Safe to say, this was pretty unfamiliar stuff for a lot of those present, and Barry didn't get to the graphical (windowed) debugger until close to the end. That actually gave us stepped execution, break points, on a simulated chip, with registers, a next program line pointer (under 500 max lines), other flag indicators, and the very limited 64 bytes of RAM (right Barry?), all conveniently displayed.
I appreciated Barry's willingness to not hold back about the nitty gritty details, even though he knew we weren't tracking in all cases.

Cultural Anthropology
Based on this news that the yellow "support our troops" ribbon motif actually got off the ground during the Indian Wars, when brave horse-mounted Custer types headed off like knights in shining armour, protecting Betty Crocker security moms back home, I'm extrapolating the early emergence of a later counter-culture, in the form of those racoon hatted Daniel Boone types, civilian trackers and company traders, who became friendly with North America's natives, intermarried.
When cultures collide, you always get these Romeo and Juliet stories wherein a younger sister or someone falls head over heels for a pagan, Roman, Jew or whatever rival ethnicity, and it's a big family crisis. One brother encourages his gang members to slay the infidel love object, while another brother, usually played as a pacifist introvert type (i.e. a sissy who better understands women) betrays the rougher bro by leaking news of this plan, resulting in an ambush of the Goody Gang and lots of remorseful suicides, including by Romeo and Juliet. Curtain. Sigh. Such a tragedy.
This pattern gets repeated in our day's Lost to some extent, in the love story between the California Babe and the Elite Republican Guard dude. But in the context of this island, with its strong magnetic fields, the predictable unfolding gets scrambled, and California Babe gets shot by the trigger happy Latina Police Chick by mistake, leaving the Iraqi Dude to mourn and eventually forgive (that's about as far as I've gotten in the series).
More predictable was the CNN banter I heard while in Florida, these Anglo pundits angsting about Iraqis and their tribal loyalties, their lack of sophistication around democracy, USAers having just proved to themselves theirs has yet to be rendered incomprehensible by an insider technocracy in charge of the voting machines (an advancing AI army, like in Terminator).
I haven't studied the history in detail, but I bet if we go back we'll find the brave Custer types were just trying to prevent all those unsophisticated Indians from killing each other, and so would side with one underdog tribe after another, just to balance things out and to prove to all doubters that the Great White Father in Washington knew how to pick a winner every time.

T Module
:: an original koski T ::(Portland Knowledge Lab Collection)
Keep filling the R mod with smaller T mods if you like, but expect smaller terminal R mods.
Phi-scaled Ts and Rs together make a cube, other shapes.
Plus if you regard a golden cuboid (1 x phi x tau (tau = 1/phi)) as defining 7 edge lengths (3 XYZ + 3 face diagonals + 1 body diagonal), and choose those six at a time to get additional phi-scalable tetrahedra, then you've got the gist of David Koski's pioneering explorations.
And remember, two parallel accounting systems: lowest terms in canonical volumes; most economical physical assembly using actual left and right handed modules.

More Pythonic Mathematics
:: protocols ::Gnubees often say "the Internet" meaning just http (hypertext transfer protocol), the one used to serve web pages (through port 80 most likely), but long before Mosaic, Netscape, IE, Opera, Mozilla... FireFox, we had usenet (the newsgroups) and ways to swap files (ftp = file transfer protocol) -- and of course email.
All of these services working together define the Internet, not just http and its webwork of interconnected urls.
After this short intro, we watched Warriors of the Net, a mathcast I've used ever since my first Saturday Academy class at West Precinct.
:: mosaic ::This time we had stickworks.py with its Vector and Edge to aid and abet, and a few students had additional shapes in short order.
My Pythonic vectors always have their tail at the origin. If you want a line segment between any two points, feed those two vectors to the Edge class to get back your edge object, which displays in the VPython window when you trigger its draw method.
:: vector arithmetic ::I pour these hard white beans from one shape to the other, reminding them of our everyday home base sculpture.
:: cargo cult geometry ::Next week: we plan to get more into animation, getting beyond static imagery. One of my students is interested in coding a planets-around-the-sun type toon. I turned him on to Celestia.

Fuller boils it down to a very simple equation in Critical Path: assuming not enough to go around (Malthusianism), we get LAWCAP (lawyer-capitalism) versus Marxist schools of thought (workers of the world unite), each claiming the competition wasn't pulling its own weight i.e. "our side" has the right to be on the top of the heap (presumably where you find the best access to scarce life support).
Per dumbed down Hegelianism (he never boiled it down to 'thesis - antithesis -> synthesis' the way they teach in grade school) we've since moved on.
Grunch is focused on artifacts and competitive marketing/ branding, but also on open source energy planning and modeling, publicly sharing lots of relevant global data (vs. keeping it classified the way Malthusians had to, cuz the news was so grim, at least for the majority of humans). World Game is still a competitive game, but our top teams don't easily stuff into 20th century pigeon-holes.
