IEEE Picnic

:: the fantasy ::

Our tour guide with the Army Corps of Engineers professed ignorance of our IEEE guild, at least with respect to our geographic origins, and so queried us before his talk, a kind of namespace check, to see if he'd need to decode the likes of BPA (Bonneville Power Administration) and/or WPA (Work Projects Administration).

As it turned out, we were mostly local yokels with or without family members. I was there with Carol (my mom) and Tara (my teen). We also visited the Fish Hatchery and saw some really big sturgeon, enjoyed coffee from the gift shop (chocolates by Ghirardelli).

Mom hadn't been here since her trans-America trip with my dad as a newly-wed (car trouble in Montana, genius mechanic).

Someone (not me) asked where he, our tour guide, was from. "Indiana, Pennsylvania" as it turned out, which was cool. I have family there too, where we both knew Irelands.

:: the reality ::

Anyway, Powerhouse One is a WPA project dating back to the original design of Bonneville Dam and Lock.

Franklin D. Roosevelt campaigned in the area on the promise of starting this project, which had huge momentum behind it.

Myopic easterners expressed skepticism that our Pacific Rim economy, rather recently contacted by Lewis & Clark, would ever make use of the six planned-for generators, let alone the 21 we're now using (that's counting the smallish two fish ladder engines on the Washington side, plus the one in Powerhouse One for local use): "the Dam of Doubt" they called it.

Transformers bedeck the topside of Powerhouse One and put stronger pressure behind the high voltage distribution networks, while lowering amperage. This works pretty well to counter unwanted power loss over the long haul.

He anticipated questions about pricier superconducting solutions such as are found in some parts of the Russian system, but doubted we'd be needing such services down here any time soon, so far south, and the very last in the sequence of Columbia River megawatt dams, which start up in Canada.

The big local news is the ongoing remodel of the generators themselves, which still contain parts dating back to the 1940s and before. Engineers are gradually switching in some new parts, including new blade assemblies, designed to be more fish-friendly plus less oily/leaky to own/operate.

PPUG

:: Jeff sharing about Python 3000 ::

I'm not sure if PPUG is what we're really calling ourselves (Portland Python User Group). We used to be PORPIG (Portland Python Interest Group). Have we morphed from pig to dog?

I got here late so didn't manage to propose anything for the agenda. I came prepared to give two lightning talks (5 minutes each): my Vilnius-OSCON talk, and the tux droid talk (with Crunchy kindly lent to me by Tara).

I did manage to catch the concluding minutes of Kirk McDonald's talk, about using his Pyd library to write Python extensions in the still-obscure D language.

Jeff talked about Python 3000, using Guido's OSCON slides, prompting some interesting discussion, in which I participated, defending Guido's decision to change the behavior of the division operator, plus mentioning his intent to standardize on Latin-1 in the Standard Library, except for strings like author name. Third party modules are welcome to go wild however, as long as keywords remain keywords.

Mark reviewed David Goodger's OSCON tutorial: How to Program Like a Pythonista while Jeff flipped through David's slides.

I volunteered my lightning talks for next time, plus enjoyed the more informal chat that came afterward -- an important aspect of any Python meetup.

We opted for the IEEE picnic this Saturday. With so few weekends left in the Summer of 2007, I want to maximize time with my family.

Esozone

:: Paul Laffoley delivering his keynote ::

I inadvertently woke Trevor to come to this, originally hyped by him as worth catching, and we were both glad we attended.

This artist, Paul Laffoley, was able to enthrall for four hours, working off some bottled water and a defibrillator. His visuals were simply stunning -- deeply alchemical, occult, weird. That's what his audience is into, and that's what he delivers. His speech, on the other hand, is first person "been there, done that" with improvised science fiction.

He's argued for eight hours with Bucky about the Mobius Strip, had that mind-blowing phone call with Kenneth Snelson, did Claude Bragdon's 4D house, a basis for Heinlein's crooked one, as if Bragdon had had the time, builds space elevator time machines in his head and paints them... Gurdjieff, Ouspensky.

A walking compendium of some of the 20th Century's best circus magic, with intimations of what's coming in the 21st. An earnest student of utopia. Shades of Hieronymus Bosch. Many allusions to Dante.

Complete with self-interruptions over others' voices, coke bottle shadows, stories of assistants he'd driven insane. Oh, and a Gaudi version of the World Trade Center, post-911. Wants to live in a Klein Bottle house, grown from some philosophical vegetable matter.

Got my 50 dollars' worth, that's for sure.

OK, time for Bridge Pedal.

Rippling DNS

I repointed my 4dsolutions.net to some new domain name servers, making them the veridical authorities regarding the hostname and IP number of the hosted archive.

In sum: I jumped free of jumpline.com, landing on some Dual Xeon at a datacenter in Houston, Texas. The move took under 24 hours.

My .py files @ Oregon Curriculum Network are once again popping source code, thanks to a documented AddHandler in the appropriate .htaccess file. I even got the geoquiz working again (uses MySQLdb in the context of Pythonic cgi scripts).

Darfur

As a local Darfurian, my goal might be to simply escape the region, visit later. This is how many people have historically improved their lives: by moving. North Americans are especially familiar with this strategy.

The global NGO community shouldn't buy the fiction that only "political prisoners" deserve something called "asylum" (relief from suffering). Rather, once you're born a human being on Planet Earth, freedom of movement is your birthright, a freedom perhaps curtailed as you grow older and break others' rules, but why does simply being born in Darfur merit a life sentence to that region?

This is your planet, as much as the next guy's.

I think Darfur represents an ideal set of challenges for OLPC and P4E people to walk their various talks.

Add wireless using satellite, hand out some laptops (not just to kids). They're designed to be self-teaching i.e. this is not a "literacy first, then computers" model, but a "literacy through computers" model, combined with peer teaching ala the South African design.

Portable movie theaters, for showing documentaries about the great outer world outside of Darfur (plus the occasional blockbuster) would also be a part of this program, though individual XO screens pretty much serve this same purpose (like that little screen on the seat back in front of you, on a fully equipped Airbus).

The Simpsons (movie review)

[Some kind of "spy kid" review, excerpted from elsewhere]

Common knowledge that Simpsons, like Google, is heavily infiltrated, in the former case through Korea, as direct infiltration of domestics is forbidden (Google through China).

Hence the cleared-for-public-view insider shots of an NSA listening center, where Lisa's worst paranoias are confirmed. Those calls to the boyfriend next door might be monitored. Emails too.

More subtle was the allusion to Marvel comix superhero Spiderman, mixed with capitalist pig iconography and long associated with selfishness (Homer) and product fetishes (as in Wired Magazine -- Bart himself a manikin sex toy in some catalogs Flanders never sees (though his boys maybe do)).

Some may see the evil hand of Moscow in all this (environ- mentalism leverages such as Greenpeace against NATO), but that paranoia's maybe too old school for most tastes ("old school" as in "during recess -- monkey bar talk").

On a more positive note American Dad continues to boost recruiting volume through at least the first few hoops, among women especially (per long term equalization goals -- gotta bring guys up to speed).

Myself: recently returned from Lithuania, toured "KGB museum" disguised as an overweight American tourist (very persuasive, even to me).

Greetings from Richmond

Some folks around here, merchants included, have taken to calling this the "Hawthorne District," but our neighborhood newsletter is still about Richmond. Hawthorne Boulevard is actually our northern border, with Sunnyside neighborhood across the way. Powell, otherwise known as Highway 26, limits us to the south.

In cyberspace, I'm waiting for a level three engineer to do something in Apache that'll make Python source files pop up on screen, like before. The takeover of digitalspace.net by jumpline.com hasn't been entirely without glitches.

I'm in a coffee shop with Derek, thinking about what to have next. A rooiboos latte, honey infused, might be good.

I'm expecting to have dinner with Dave, missing Wanderers this time. Martin Zwick is presenting on his paper Systems Metaphysics: A Bridge from Science to Religion. I made some comments in the egroup about it, which I'll now dump to a world readable text for public linking purposes.

We were hoping Larry might join us at dinner this evening, but he's tackling his basement, trying to diagnose a problem. Derek may be otherwise occupied as well.

Tara phoned from a mountain wilderness area covered by Verizon, saying she's having a great time hiking with Larry's Chris, Jane, June and Luci.

The call came while I was in said basement, enjoying slides of Amanda's wedding (Chris & Larry's youngest -- their eldest, Greg, is by now back in Moscow).

MetroFi continues to expand its coverage of Portland neighborhoods, per this browser mashup. [update: that link goes nowhere now, as MetroFi later quit the scene, might never have had a clear storyboard in the first place, hard to know].

Programming for Everybody (P4E)

I'm in this very high ceilinged venue, the Oregon Convention Center, listening to Guido outline his plan for transitioning to Python 3.0 via Python 2.6, a bridge version. I like that he offers a strategy, not just the changes themselves. He gives himself a responsible role, not too heavy, not too light.

In that vein, I don't want to saddle him with a lot of Python in Education content he never signed his name to. CP4E was his original abbreviation, used to secure some funding for IDLE. Although I want to acknowledge the heritage, the influence, I'm not wanting to get him in trouble if I take a dead end path. So I've doctored the slides to say P4E more frequently, dropping the C. Plus I have HP4E to play with (these days, everyone thinks "HP" means "Harry Potter").

That may not sound like much of a difference, but legalistic types don't need much of a difference, to see the difference, so I'm feeling good about this change.

So I'm up next. I published some notes just a couple hours ago, to edu-sig, to help focus my mind, keep me on track.

Technical note: digitalspace.net, the ISP behind 4dsolutions.net, was acquired by some new company. The process of website conversion has apparently partly broken access to my site. I've opened a trouble ticket. If you can't access "the slides" (above), please be patient and try again soon. Embarrassing to develop this glitch right when I'm making my work more public.

I stayed late to hear Larry Wall's State of the Onion, right after a great auction (Perl people are so cute).

He confirmed my impression that Ruby really owes more to Perl than Python.

Most of his talk was about the different dimensions along which scripting languages vary, netting a big phase space. And let's own "scripting" was his advice (Perl has no hope of shaking the label). Don't fight it, just change its meaning if that's what you need to do.

Geospatial and Open Source

I'm attending a talk on the effect of open source on geospatial. The database and CAD packages are being geospatially enabled. New views, giving fire fighters a real time simulation of the insides of buildings, of what's under the street, are becoming commoditized.

"Think of SimCity but with real data" said Geoff Zeiss of Autodesk.

Geospatially-enabled IT plus Web 2.0 means General IT is absorbing GIS, resulting in a convergence of hitherto separate cultures. GIS is also converging with CAD.

We're also seeing new open geospatial standards, such as SFS, GML, web mapping service (WMS) and web feature service (WFS). ISO's SQL/MM includes geospatial extensions. OSGeo has matured.

Given the field forces have lots of retirement age personnel, there's a big need to update telco and utility records so that coming generations know where stuff is. Historically, central data repositories are significantly out of date vis-a-vis what's true on the ground.

Ajax Tutorial

Our forum leader is top notch, a true master of his field, able to spin up an OS + Browser in almost any permutation, in order to better empathize with his users, and kill their bugs. His name is Alex Russell, an author of Dojo Toolkit, count me a fan.

For those of you who don't know, Ajax is a foundational technology of Web 2.0, a second wave of browser bling, courtesy of a Renaissance in browser technology. Microsoft actually gets a lot of credit, for introducing an ActiveX control for interacting with a host over the wire in the background, with no click sound in user space.

The basis for dynamically changing a web page, without a reload, without an audible click, was born. Other browsers quickly followed suit, obviating reams of workarounds and hacks that had made this stuff too esoteric for 99% of developers.

I wasn't so aware of JSON before: a non-XML solution, quickly handled by eval() on the client side to create a data-rich Javascript object. I also finally installed Firebug for which Alex had plenty of high praise.

Idiomatic Python

I parked Razz near Hollywood and took the Max to the Portland Convention Center. Two geek circuses are already in full swing, so I'm walking around with two badges, two bags with bling.

Now I'm in Code Like a Pythonista: Idiomatic Python by David Goodger, who works in the financial sector, which explains all these (portfolio, equity, position) examples, in addition to the more typical Monty Python based ones, as in:

>>> given = ['John','Eric','Terry','Michael']
>>> family = ['Cleese','Idle','Gilliam','Palin'].
>>> pythons = dict(zip(given, family))

Although the content is very basic, I'm finding it of excellent quality. Safe to say: some of these idioms won't survive into Python 3, but mostly he's encouraging good habits. For example, given the 'in' operator works on so many collections, use 'key in dict' not dict.has_key(). Be less idiosyncratic, i.e. when possible use the more common pattern versus the too special case.

Hey, collections.defaultdict is a pretty cool tool. maybe using int as a factory function, though note you won't get any "no key" errors (it'll just create a new one).

I surprised myself this morning, what with all the switching among laptops and cases: not until I got to the conference room did I realize I was lugging the Toshiba, not the Dell, meaning I'm in Windows, not Ubuntu at the moment.

Good chat with Lars Lohn, now contracting with OSDL on the OLPC project. I hope he introduces me to Justin, a project leader and student, also speaking next session. Lars and I remembered each other from our conversations two years ago. I also met up with my old Plone friend "fifer" (Richard Amerman), plus encountered Kevin Turner (FreeGeek) in the Ubuntu Zone, where I am now.

Maybe I'll finally hook up with Don this evening? S'been a tad hectic since getting back from Lithuania. Tara is still count down for lift off. Hey Nick, leave voice mail if you want me to get back to you. I'm unresponsive to simple vibrations.

Transformers (movie review)

The future of humanity is at stake and it's all up to this boy and his cube, with help from the muscle car, and in hopes of winning the heart of this girl. Not a new storyline, we all realize (OK well, maybe the cube part's a little different -- kinda Borgy -- but not the robots, although these ones are quite expert at disguising themselves by curling up).

The Pentagon was happy to show off its best toys, in this wash of eye candy. A broad cross section of kids, some adults, get a character with which to identify, plus many will see the car they want to drive, or truck, one of the many airplane options. Flatscreens galore. Department store bling. Lots of shopping ideas.

Was the whole point of that little dog to embed a link to Taco Bell? Lots of amped up brand name iconography, blended with other governmental, patriarchal, patriotic razzmatazz and symbols of authority (scenes of national security goons bossing USA homelanders were a focus in The Last Mimzy as well).

The autobots themselves might be cast as advertising something more abstract. How about the ability of capitalism -- the cult of imaginatively using one's head -- to morph endlessly, if sometimes only one-dimensionally.

Transformers is a loud nerve-jangling ride with lots of bovine growth hormone or testosterone or whatever that is. Amusement park stuff, cram packed with clichés. Enlist today. Serve your country.

Wanderers 2007.7.18

Dr. Moira Gunn is our guest at Wanderers this morning. She's chatting away about Philosophy Talk (she's a fan), the possible two channel solution to the need for more tech talk on the public air waves.

But mostly she's talking about her new biotech book (martini glass on the cover).

Speaking of that martini glass, why do hardened journalists carry hard liquor around (a stereotype perpetuated by many movies)? You can disinfect a cut with it, brush teeth with it, bribe with or give it as a gift, plus have fun with it. Even journalists who don't drink have been known to lug some liquor. And why scotch and not vodka? Easier to see if it's been diluted, plus how much you have left.

Now she's talking patents and big pharma in the context of a world economy, analogies to the music industry, trends in the price points, Brook Shields' tatoos. Obviously I'm in the presence of a true teacher, not "just" a journalist.

Earlier, we went around the circle introducing ourselves, giving thumbnails. Terry did his "I'm a contrarian" speech, some threw in deep questions (Don: "what hope do we have?"), while I pulled off a fifteen second version of my stump speech, this time with the added spin of having just returned from Vilnius, with lots of Wanderers happy to see me, me them. Hi Nancy!

The other aspect of my morning is I'm needed on stage for Day Two of this Saturday Academy class on Pythonic Math, a strategic Silicon Forest pilot.

I'll treasure this brief partial overlap with Moira as the sweet encounter it was for me.

OK, back to Razzmatazz, my trusty Subaru, waiting outside.

Sunday in Vilnius

I enjoyed a quiet Sunday in Vilnius with young Geoffrey French, author of gSculpt and gSim, plus a professional graphics designer using 3ds Max in the UK.

We ascended Castle Hill, a thousand-year-old site, then had lunch in Old Town, comparing notes on such topics as soccer hooliganism, South Park, Ali G, and Ricky Gervais in Extras and The Office (also meta-classes in Python).

We also visited an amber museum. Fossilized tree sap, oft times with "inclusions" (insects especially), dating back 40 or 50 million years (or more) is an important extract in the local ecosystem.

Baltic amber is typically mined off shore, or from a patch of "blue earth" in Russia. Tons of the stuff are recovered every year.

I bought some tiny dolls-in-within-dolls for Tara.

Python in the Control Room

I started my second day at EuroPython learning about how ConocoPhillips is using Python to improve integrated operations of North Sea oil platforms in onshore control rooms.

Coin3D wrapped in Pivy on top of a database, serving out through Qt, gives operators real time views of the drilling platforms and surrounding vessels. We zoomed in on the Ekofisk field, checking out weather conditions, logistic features (e.g. vessel trip planning, viewing cargo manifests).

The demonstrated application implements collision and speeding detection, sea bed visualization. Applying a dynamic language such as Python was a big experiment and considered a success. Our speaker was Roly Seehaus of Kongsberg.

Fabio Pliger from the University of Verona also cast his talk as a success story regarding Python's ability to perform in real time, generating critical feedback, this time within the pharmaceutical industry.

His shop is still Windows-based, but Python plays well with others.

I next learned about the somewhat experimental PyConsole.py running atop Python's win32console module. This gives users a Windows compatible command line, atop which another Python interpreter might be loaded.

By use of callbacks, one might use multiple consoles to leverage the operating system's multi-processing capabilities (e.g. instead of Python-level threading).

The speaker, Michael Graz, also demonstrated using AJAX to invoke a server-based Python command line from within a client's web browser.

The Pygame guy unfortunately had no sense of time. Though obviously a genius, we barely got to the core substance of his discussion (tmap, RenderUpdatesThreaded).

Jonathan Fine of The Open University in the UK demonstrated the public MathTran server (mathtran.org) designed to put mathematics on web pages. The service takes math formulas written in Tex and sends back an image for web page embedding. Python glues it all together. Let's give it a try. Sending \sum_{k=1}^\infty \frac{1}{k}, receiving back the following png:

.

OK, cool.

On the agenda: two way translations between TeX and MathML.

Johnny Stovall, a wild man Texan expat from Indonesia belted out his Data Driven Parsing for the Real World. The guy's been on a 36 year mission to develop a utility he's been told is impossible (he's been nicknamed "the impossible man").

But what is a data driven parser and what is it for? It doesn't depend on an exhaustive rule-based description of a knowledge domain or human language.

Mostly he talked about how computers complement humans by accomplishing tasks that humans cannot (but I think we knew that).

I believe until what he's looking for -- some kind of very generic pattern recognizer -- is better defined, the kind of non-computable problems he imagines tackling will be handled on the human side of the fence, though with the aid of computers. I don't think we're quite ready to do Python sprints to solve the perennial problem of creating an Artificial Intelligence.

Connecting the Dots

The talk went OK I thought, in Zeta (all the rooms have Greek letter names).

The gist:

Students like to be clued in regarding technology, especially when it represents the promise of better living standards. Calculators shouldn't artificially delimit what we mean by "technology in the classroom."

Understanding of computers, how they're programmed, gives a deeper appreciation for "how things work" in many walks of life e.g. data bases are prevalent.

Mathematics and computer programming need to be better integrated from an early age. The object oriented paradigm (OOP) brings some unifying heuristics to basic mathematics, as we're able to cast polynomials, vectors, polyhedra, rational numbers and so on as "math objects."

Working backward from a vision of the future in which many more people are much more computer literate, we need to ask ourselves: how did we get here (a more enlightened world) from there (the dark ages past)?

P4E succeeded not because everyone had to learn Python or had to choose computer science or programming for their profession. Rather, we converged problem solving skills with coding skills, code being another kind of mathematical notation (the machine executable kind).

Our integrated approach also involved connecting the lexical to the graphical, keeping the so-called left and right hemispheres of the brain integrated.

For eye candy I had my hypertoon projecting as people took their seats. During the talk I rotated the Beryl desktop cube a few times, switching to various websites.

For example, I demonstrated looking up 1, 12, 42, 92... in Sloane's On-Line Encyclopedia of Integer Sequences. We might use such sequences to motivate writing a few Python generators.

I didn't actually have time to run any of my source code, nor even explore it in much detail.

I only got two questions, one about whether I get any income from my teaching (yeah, some) and one about H.S.M. Coxeter and his possible influence on my curriculum writing (he's one of my heroes, helped give focus to polyhedral numbers).

There were some microphone problems and page up/down weren't working in OpenOffice so I kept resorting to the mouse wheel, which was awkward.

Ratatouille (movie review)

The food critic, mirroring a film critic, delivers the moral of this film: anyone might be a cook (film director, great actor... food critic). What that means is: not everyone is born to do just anything, but anyone you meet might be a genius in ways that surprise you.

How this movie teaches its lesson is by setting up a lot of interspecies bigotry (not hard, as it's real, at least on the human side), with the crossover being quality food, in which members of both species are true believers, but this one rat in particular: he has the right stuff.

Although a kids' cartoon, I found ways to piggyback my adult reveries, about kings and queens and their inner circles 'n stuff. The word "democracy" is still echoing from Michael Moore's latest (a certain UKer was most eloquent about it), and the Quaker idea of "that of God in each and every" -- easily mappable, as a maxim, to "the genius light within" or St. Augustine's "inner teacher."

The rats inhabit a kind of Hades, a netherworld. Remy overcomes his misanthropy enough to actually become one of "them" (joined in his loneliness by his idol, one recently departed) if, that is, you think looking out a man's hat, puppeting his limbs, might just be a metaphor about the mind-body relationship ("naw, Disney? Philosophical?" chuckle). Think "rat = homunculus" in this case an ego dealing with class and personality complexes (shades of Flushed Away).

This was a family outing, with Tara to my immediate right, then Julie and Carol. Later we split up a bit, me heading to Men's Warehouse (redeem a coupon, shirts for Vilnius), Tara to American Eagle, Carol and Julie wandering an old haunt. We rendezvoused at the ice cream stand just outside Macy's, Carol's treat, and drove home.

My thanks to Tara for filling my iPod with a lot of good music. Tonight's listening: Blue October: Into the Ocean, Hate Me (Tara and I agree there's a lot of talent here).

River Views

Personal Workspace

A control room may be as humble and spare as one laptop and one child (the controller), which is close to where I am, except I'm a grownup. My one laptop (the other one's in the closet) is now the wildly popular Dell Inspiron E1505, a duo-core jobber, running Ubuntu, in my case with Beryl 0.4.2 (a release candidate).

CubeSpace, which hosted the wildly successful Portland BarCamp a few weeks ago, is premised on this model: find your cube and fit in. Doesn't have to be the same cube every time. Join a counter- part cube farm in Tokyo. Flit about, a wandering cube farmer. Except I've always envisioned my PWS as a tetrahedron in GST, but that's just my Fuller Schooler aesthetics shining through the covers.

So O'Reilly's Safari Unleashed or whatever they're calling it, proved its weight in gold just now. After fighting the problem for hours, as to how to get my 1280 x 800 desktop to share out to my 1024 x 768 Optoma or some like-minded projector, preferably on both screens simultaneously.

Answer (as I found by browsing Safari): use the Ctrl-Alt-Fn-minus to lower the resolution, which'll make that 1280 x 800 surface (one side of a cube of two caps and four desktops) into a virtual desktop not quite fitting in its little brother window. I can live with this outcome.

What's amazing about this nVidia card is it'll then play a DVD movie through both displays simultaneously, though I don't ask for "full screen" as that'd mean "partly off screen" in my space. My Toshiba, the one in the closet, hasn't mastered that trick yet.

Deja Vu (movie review)

I'm just focusing on one particular scene here, wherein Doug Carlin, played by Denzel Washington, throws a kind of tantrum in a control room, breaking a monitor.

Why does he do this?

He's being let in, as an insider, to the core counterterrorism center, the better to do his job. The monitors show events four days in the past, which the experts claim is based on satellite feed and some post processing.

Carlin does some empirical testing of his own and confirms his suspicion that he's being lied to, which is when he throws his fit. How can he really do his job most effectively if he doesn't have a realistic grasp on what his degrees of freedom really might be? Is he actually able to retroject himself into the past? He really needs to know this, and he tries to hammer that point home.

I found this scene effective in that I wasn't buying the satellite feed model either, as I kept telling Tara. Besides, we both knew from the previews that time travel was somehow involved. My impatience found cathartic expression in Carlin's throwing a fit. He's just trying to do his job, so why all the BS?

Carlin and the other controllers have witnessed a horror and will do pretty much anything to prevent it from happening again -- or might they really undo the past itself, even at the cost of erasing the present? Yes, apparently.

Within the domain of timeloop science fiction (12 Monkeys being another of that genre), this one resolves nicely, like a clever slip knot.

Summer Retreat

Wanderers gathered at Joe's place in Oregon wine country, to learn about his long term experiments in horticulture and forestry, and to compare notes on practically any subject under the sun.

Given the Willamette Valley's almost Mediterranean ecosystem, with drenching cold winters and hot dry summers, a relatively small set of plants and animals are good to go here.

Although redwoods and great sequoias grow in largely separate bioregions of northern California (along the coast and in the Sierra Nevada respectively), Joe hopes his experiment of interleaving the two species will work well on this property. Once these trees are big enough, they tend to create their own self-sustaining micro-climate.

At one point I felt we were becoming too cult like, with the sun beaming down between rains, listening to ourselves chatter in the well lit, finished barn (more of a workshop). When people prefer the sound of their own philosophies to unedited Mother Nature, that's a warning sign.

I left the group and hiked up to the old oak, taking in the view, coming down from the mountain with a message for my peers: "you're all crazy" (I got a few nods of assent). But the group was transitioning to the outdoors at that point. Joe cleared a main trail with his Kuboda tractor and before long we were all guzzling Nature's Own kool aid, taking in the forest.

And besides, we are an interesting group, chat wise.

Listening to Gus and Bob blab about who they know in common in the Mars Society, what experiments they've been up to, what telescopes made, articles read and/or published, is all very entertaining and enlightening to boot. Too bad I'll miss Gus's upcoming talk on time lapse photography, which I expect will be excellent.

Terry was busy spinning thermodynamics, channeling Greek philosophers. Gloria led a discussion of family design patterns in relation to ethnicity. Phil, the book store owner, suggested I read up on those tough guy Teutonic Knights given I'm heading to Lithuania soon.

Another Control Panel Fragment

ProQuest search panel
(with special thanks to Trevor Blake)

As a card carrying Multnomah County Library user, I have access to the New York Times historical database, which includes ads as well as articles. I've been using the above control panel to scan for relevant projectable citables to help my audiences get a grip on some recent history.

Here's an ad citing Bucky's infamous "nature is not using pi" meme, which in 1980 sounded fresh enough to serve as a recruiting tool. This company is looking to hire some new crew members.

NYT ad: Apr 27, 1980 pg. F33

So that's Shirley Sharky on the left (below). I got to meet her in Ed's Georgetown apartment during that big shindig in 2004 he cohosted with his daughter Ashton, with foci of her own.

I got to share lasagna with Thomas Zung and Shoji Sadao as well. Dick Fischbeck was in the little kitchenette where Ed kept the gin.

Anyway, I tend to get a little giddy when I'm around so many beautiful people all packed into a single meetup like that.

NYT article: School of Tutors Uses World as Campus,
by Sharon Johnshon, Sep 7, 1980
(Janet Bergman with glasses)

Now it's time to watch the evening news with Katie Couric. Tonight's closing story: Lake Superior is at an 81 year low. How low will she go? Container ships are especially affected.

Today's Confabs

I joined a tetrahedron of phi guys today: DF has been studying the spiral; GS knows sacred geometry; DK (who phoned my cell while I was having Thai food with DF); myself.

Chatting with DF is always a pleasure. He knows lots of tricks I don't, just as CalTech has fared better at providing email to its alums, Princeton's TigerNet having caved under ambient conditions within Spamalot, our trashy cyberslum.

I'm boosting coffee consumption, beans from Burundi, cutting back on other calories (I have plenty in storage).

DF and I spent a pleasant quarter hour exploring the OED around "jerk," a real name for the third derivative at Boeing, where people value smoothness as a passenger experience.

r = pow(math.e, theta * (2/math.pi)*(math.log(phi)))

DF: the successively shrinking quarter-circles-in-squares in a phi spiral aren't exactly quarter circles. That f(x,y) = 0 would put too much jerk in the joins.

OED: another meaning is to "jerk out" something sage between draws on one's pipe, not quite the same as "blurting" nor "pontificating" either.

This association with witty, whip-like quips, is in stark contrast with another meaning of "jerk" as in "slow to catch on," "a dim bulb," a spectrum mirroring people's differing experiences of the same performance on occasion.

Judging was a major focus of our lunch as well.

DF's visualizations around the science fair model, of judges ranking projects with an eye toward awarding prizes, have been evolving for some time now, a fascinating process to observe and to learn from I reckon.

GS found me at the supermarket, looking for butter pecan ice cream for mom, mint chocolate chip for Tara. We then co-spiraled down the beer aisle.

I returned DK's call from earlier. He's recovering fast from an injury, has almost finished the new garage.

Always a Marine

I just listened to John Rushing's latest interview with Terry Gross, regarding his new book and career as a correspondent for the English language version of Al Jazeera.

Given the etymology of this blog, and my tracking of Rushing's career, I feel obligated to comment; the relevance quotient is so high.

And my comments are very positive. Count me a Rushing fan, even though I don't get Al Jazeera on my DirecTV.

Computer Anatomy

My last upgrade to Camtasia Studio cost me easy access to sound features within the application, owing to my exotic integrated RealTek circuits, stardard on these HP Pavilion a1630ns, but that still doesn't mean there's a huge intersection of app users willing to press for a solution (by running diagnostics, sending screen shots and so on).

In the meantime, as new C stuff is hammered out, tech support advises that I slip into something more Soundblaster-compatible. Here's the polite letter, which I'm not complaining about, simply sharing:

Hi Kirby,

We found that this is a specific issue with Realtek intergrated sound card. We are currently working on ways to accommodate the rare integrated type of sound cards that seem to have issues with Camtasia.

In the meantime I would recommend purchasing a Sound Blaster sound card as we have always had good success with those working with Camtasia.

Please let me know if you have any questions.

Kind Regards,

Mike

OK, so I could dissect the Santa Cruz card out from KTU2 in the basement -- the unit swapped in to replace Jennifer, once I repurchased the latter from Derek for display in the Pauling House as a generic, well performing Ubuntu box (from where I'll sometimes post to my blogs, such as during Wanderers meetings, like when not lugging my wireless Toshiba Satellite) -- and transplant it into KTU3.

On the other hand, those Camtasia movies were more "proof of concept" and're still out there doing work, so I'm not all that knickers-in-a-twist (as Brian might put it) over the vacation I'm getting from making more mathcasts and/or pilots for ~M!. Let's give would be sponsors ample time to evaluate the merchandize. I don't believe in being too pushy.

Oceans 13 (movie review)

Some friends invited me to this on the basis of free tickets they'd received, handed out by Regal in compensation for some glitch, Jimmy said minor, in some HD showing of Pirates... on a big screen in the multiplex across from Lloyd Center, the one with the parking lot from which Robin Egg was stolen, our Subaru wagon pre Razz, along with her bicycle rack. Miraculously for this Friday night, Jimmy found a space right at the entrance.

In the mood for mindless fun, I gave this movie big benefits of the doubt. None of that could actually work in real life, starting with floor plans, which is why they had too many to show. Everything would be totally broken, starting with the lame explanations for how a tunneling machine could be run by one man. The audience gets taken. The casino wins again.

But the point isn't the claptrap, the bells and whistles, but the clear friendships and utter competence of the guys in the foreground, a rat pack for our age. This is a shared vehicle well shared, by a sensitive bunch of Oprah lovers, what can we say. Not quite as high level as Shark Tale perhaps, but still a crime family drama, and those tend to be good once we're above certain cut offs.

Greco was the furthest off the mark. So what he (a thinking computer) detects short term deviations from average outcomes on the tables, and so what some big winner acts not innocently surprised, but like he expected it. So whatcha gonna do, big guy? Deviations happen.

Control Panel Fragment

My default screen is a personalized one of Google's. I play around with it, swapping gizmos in and out.

I get a Buddhist thought for the day thing via RSS, which I don't always check, but I popped it just now:

War can only be understood and put an end to if you and all those who are concerned very deeply with the survival of man, feel that you are utterly responsible for killing others. What will make you change? - J. Krishnamurti

That reminds me of some stuff I wrote awhile back, but I'm not finding it right now plus I'm noticing lots of badly formatted pages at my grunch.net web site. I need to go into janitor mode again and clean things up some more.

Patter About Poets

So I'm to understand from today's park meeting with Mitch that Emerson had no problem with all the sex in Whitman's poetry, but maybe from a coaching angle encouraged him to throttle back.

Plus T.S. Eliot was of course quite a bit later on the time line and in a very different social situation, must have disdained Whitman's work for being unschooled. "Poetry is not mere metered exuberance" -- but nor is Walt's.

The proof of transcendentalism is in its pudding. We eat our own dog food as some geeks like to say.

These remarks are with reference to this excerpt from my Connecting the Dots:

Emerson liked Walt Whitman a lot but thought there was too much sex in his poetry. Whitman refused to back off -- much to the disgust of T.S. Elliot -- probably with his future HBO-minded American audience in mind (i.e. he was prescient).[i]

Fuller of Harvard comes later in the game, dubbed “World Game” by him, with “Guinea Pig B” a star player. Fuller, an inventor, invented his own namespace fairly completely, after taking time off post 1927 to thoroughly divest himself of any unwanted “reflex conditioning,” and laying the groundwork for some life-long self-disciplines, somewhat described in his penultimate non-posthumously published magnum opus Critical Path.[ii]

So I probably need to study the writings of Emanuel Swedenborg to better understand cultural currents linking the 1840s and the 1960s. Could be some fun airplane reading.

Pioneer Century

:: tinkerbell ::

Today I joined Chris and Larry for Pioneer Century, one of Oregon's oldest organized cycling events.

We chose the shortest loop (45 miles). Whereas the workout was a real pipe cleaner for me, it was even more of a milestone for Chris, who started noticing troubling health symptoms during this same event last year. This year she conquered the course.

Part of the reason physically active people live longer on average is they notice changes earlier, when pushing themselves to perform. Many illnesses are far more subject to treatment if caught early.

Only a few cyclists marred the event by disrespecting signage and taking to the middle of a busy highway. Local motorists, always courteous, put a bright face on these antics, accepting that some tourists may be prone to goofy behavior.

Yesterday I put some finishing touches on my sixteen page Connecting the Dots: American Transcendentalism Meets Pythonic Math and sent it off to the Europython folks, with strong encouragement from my community. I might tweak it again slightly before putting a copy at my website.

:: playground at the half way point ::

I came home to some terrible news about a friend's 22 year old son's fatal car accident. My heart goes out to my friend and his family during this time of painful separation. I am lighting candles and sending them metta as my dear Dawn would say (and do).

Design Science

Last night marked the completion of my Python for Wanderers course, during which I shared a new storyboard for using Python in the field to teach analytical thinking.

We don't always call it math (~M!) as it's more a mix of subjects: philosophy, computer science, graphical arts... music.

We're hoping to leverage the capabilities of the new technologies, including these inexpensive laptops now coming on the scene.

Flextegrity.com has been investing in X3D recently, another way to make graphical material interactive and "fly through- able" (Octaga actually has a little paper airplane icon signifying "fly through").

I've embedded a screen sample. Plus there's been a lot of structural analysis going on behind the scenes. Sam was by 4D Studios not long ago, with the latest hardcopy version.

Yes, I agree, it looks a bit like the obelisk from 2001.

Laptops, Intelligent use of

Intelligent use of laptops (setting): the lecture hall is large and the teacher far away, the chalkboards too. Given there's a camera or two, recording for posterity, it's easy to patch in to the camera feed and see what they're seeing (the producers in the control room), like sports on TV, everything close up and clear.

That's using a laptop, everyone with sufficient bandwidth to capture the feed, with headphones if desired.

Of course the temptation to multi-task presents itself. What did she say again?

Teachers like to day-dream that "undivided attention" is behind all those dreamy eyes out there. Laptops simply make it more public: no, other thoughts are happening too, get over it.

At least let 'em control their own thought process, how 'bout it?

So if you're a lecturer, you might see a lot of student eyes pointed not at you, but at a screen below eye level.

But they're watching you, through eyes on the ceiling or wherever they put the cameras.

Unsettling? Maybe. But at least it's easier on the eyes, plus your lecture is getting saved for future polishing/editing (spin doctoring), such that your "greatest hits" become a salable compilation someday.

So maybe you'll be free to retire from showbiz then, and try out other pastimes, thanks to all those royalties or whatever?

Middle School Program

Friends as in Religious Society of, with many lowercase among them, have gathered to plan future meetings, which sounds boring I know, but that's what we do: meet. For some, that's in anticipation of some future action. For us, that future action will minimally include meetings.

I served as chauffeur this time, escorting my middle schooler, lugging a laptop. I'm not trying to steer stuff at this level, got me blogs to keep current. So I'm back in a corner office while the meeting, after some pizza, gets under way.

Earlier today I wore my tie to some business meetings regarding this or that data, database programmer that I am. Not that I always wear a tie of course, but I've been shopping recently, and felt like road testing some of the combos, having tried out the completely new suit on my birthday recently.

OLPC on CBS

Lots of geeks were cued to watch this segment on OLPC on 60 Minutes this evening.

I was first to publish a review to edu-sig, Python Nation's "Python in education" list (hosted at python.org).

Excerpt: "Negroponte himself comes across as a class act, handsome, well spoken, an idealist we can love. So the XO uses AMD chips, so what?"

In other news, Jason has agreed to take on Python Meetups in Portland, via the Meetup.com infrastructure. Per Kevin's input @ BarCamp, we've created an official (python.org) mailing list for Portland as well. Thanks to Brad Allen of Dallas for hitting the restart button.

In my inbox: finish downloading Ubuntu Studio (37%), prepare and mail an NTSC DVD of my Dawn's bio & slides to Pat MacAodha; blog screen shots of Google Sketchup (free) doing domes 'n stuff; read more of George Tenet's "encoded spy novel" (I've enjoyed it so far, especially playing "musical chairs" in Georgia).

Sam called; we talked about poets. Dad'd be 77 today.

Incompleteness

:: rebecca @ island cafe ::

As it worked out, my surprise birthday present today was to hang out with Rebecca Newberger Goldstein, our guest ISEPP lecturer, tonight rounding out the 2006-2007 series with a talk on incompleteness. Terry managed to schedule a quick lunch-focused trip on Captain Donzo's Meliptus, with me 'n Glenn on crew.

Rebecca did some hard time in 1879 Hall (Princeton's philo building), at the grad level (I was undergrad), escaping the limited options a trully orthodox Jewish curriculum could have provided a woman of her day. We gossiped and/or compared notes on a few of the big names for which Princeton is famous e.g. Kripke 'n Kaufmann.

Rebecca and I are both Sasha/Borat/AliG fans, so using my faux AliG voice I asked "if Gödel was on Myspace, who would his Myspace friends be?" Rebecca responded without hesitation: "Einstein and Leibniz." Me: "but Leibniz was dead." Rebecca: "They're all dead." At which point I broke character to speculate how three hundred years from now, Myspace might include as many dead as living (the info'd still be of historical interest no?).

Post lecture: Gödel would've nixed Wittgenstein as a Myspace friend at the time, especially as LW was being hailed as the god of logical positivism (a gross miscasting) whereas Gödel was into proving his brand of Platonism still held water. Rebecca: definitely one of Gödel's best Myspace friends.

Wanderers 2007.5.15

Scene One:

Mom got a computerized call in the wee hours of this morning informing her of a change of itinerary on United Airlines: her flight had been canceled, with the new one scheduled in at 8:30 PM instead of 3 PM.

Arriving early at the airport, given the pre-scheduled shuttle, she rebooked via Seattle but that flight was pulled for safety reasons, after passengers had already boarded, meaning she's now wait listed on the flight in at 8:30, with a backup confirmed in at 10 PM.

We call that "being jerked around" in the airline biz, but fortunately the customer in this case, age 78, is a veteran flyer and knows how to roll with the punches.

On my end, it's an ever-changing pickup time, meaning how much of Wanderers I'll make is still a mystery.

Scene Two:

Nirel did a great job laying out her dream of a cafe/lounge in this particular Seattle property that speaks to her. I've written about her project before in this blog. We all know I'm a big Nirel fan, in addition to being a Katie Couric fan. Count me a Condi fan too, talk of policies aside.

Scene Three:

Mom really felt for the airline clerks, especially this one who got 130 unhappy campers from the deboarded plane to Seattle, some missing international connections, all lined up and mad. Her own scenario worked out pretty well, with a comfortable seat on an Airbus that arrived some 20 minutes early, closer to 8 PM.

Tara and I retrieved her, and her bags, from PDX. She was amazed and pleased that her bags had made it as well, given her earlier wait listed status.

Prepping for Class

output from first draft of povtoyz,
after rendering in POV-Ray

Python for Wanderers, part three of four, is tonight, and I wanted to be up to date with part three for Saturday Academy, which I'm teaching @ PSU. To that end, I wanted something like VizToyz but geared to work with a ray tracer, POV-Ray, instead of VPython out the back end.

In writing povtoyz.py this afternoon, I finally noticed my polyhedra.py was eight faces shy of the full complement for my Icosahedron subclass, duh. I hadn't noticed because I was so focussed on the wireframe view, but once I got experimenting in POV-Ray, the defect became obvious, as faces, defined by POV-Ray's polygon primitive, were missing from I, Icosa (a menu option parallel to the one in viztoyz.py).

today's scribbles

Jennifer is presumably on her way over the mountains, if Judy was right about finally finding a rental car. Not someone I've met before, but she may come to Wanderers as a part of her tour of PDX.

Another feature of the upcoming Wanderers class will be to review my work with Dr. Bob Fuller and team, getting that Studies in Human Motion CDR ready for the summer '04 meeting of the American Association of Physics Teachers.

I used Python + POV-Ray for my part in that project, starting from Excel spreadsheets giving the successive (x,y,z) spatial locations (rows) of several sensors (columns) affixed to a ballet student going through her moves in Lincoln, Nebraska. Each row became a frame in a POV-Ray film, with my Python code doing the conversion (included as open source on the CDR).

At the Lab

Nick and I are waterholing @ Lucky Lab, connecting through PersonalTelco (he's on a MacBook, me the Toshiba, nowadays with a gig of RAM). Nick's just back from four months in Europe and Canada, including Ireland and Toronto, with lots of stories.

I was late to another power lunch with Arthur, the retired Ecotrust and AFSC VIP, because I was countering the carpenter ants in my garage. Arthur gave me his blessing on that, eco-unfriendly though I'm being. We ate at Portland Fish House, just a tad towards Mt. Tabor from Pauling's on Hawthorne.

Power lunch with Terry Bristol yesterday and Mio Sushi, just prior to a power walk with Trevor and Sarah-the-Dog to Laurelhurst then Ben & Jerry's. Trevor updated me on the twisted history of Oswald Mosley, with the partnership ending up buying the Obey Giant artist's hardcover magnum opus at Missing Link for $60.

Python meetup tonight, organized by some geek from Dallas. Looking forward.

I'm drinking Crazy Ludwig for beer, their signature Hawthorne Best Bitter being off line. The guy behind the bar said it was named for van Beethoven; I thought maybe that Neuschwanstien guy.
