Mambo Taxi

The last week has seen me:

* startle Neil Stephenson [1]
* have an annoying contact lens incident [2]
* apply the necessary teachable-moment to a kid outside my workplace who was messing around with my bike when I left the office
* meet Stewart Brand
* watch a superconducting toy train, a sort-of real quantum computer and a really pretty 3-d movie which was narrated by Stephen Hawking [3]
* document the activities of the zombies at City Hall. Well, the zombies attracted to City Hall by a certain video. This was surprisingly fun.
* play with a working reprap, a supposedly self-replicating machine. [4]
* be part of creating and solving various problems; technical, social; problems of planning and problems of execution. Be pleased with some outcomes. Be exhausted at work, but not too exhausted.
* see melted_snowball off on his trip to Japan. Missing him a lot.
* not get enough sleep. Not get the rounds of bugs that are sweeping my workplace. Now if I can just get my flu shots before I have any flu symptoms, I'll be even happier.
* feel simultaneously lonely and not like talking to people. Sometimes I wish I were wired to be more social.
* spending quality time with Rover.

[1] I saw Neil Stephenson speak twice last week; afterwards, I thanked him for providing fun role-models for geeky people everywhere. I offered that I was occasionally inspired by Sangemon, the "hero" of Zodiac, whose style of bicycling in Boston traffic was over-the-top assertive. Neil looked a bit nervous at this- "I hope you do that safely." I laughed. Anyway, he was very polite.

[2] on second thought, I won't describe it. Not fun. [5]

[3] The toy train zoomed around a magnetic track. The "train" contained a super-chilled magnet and it was propelled by a shove from the demo-guy. The "quantum computer" was very poorly explained by a volunteer docent but it had an oscilloscope readout with a squiggle. And a plexiglass and metal assembly. Sorry, but that's all I got. I found my favourite part of the video, animated by NCSA - flying from the western spiral arm to the center of our galaxy. This was the most effective use of 3D I've yet seen.

[4] This evening I went off to the local nascent "hack lab" (clubhouse for tinkerers, more or less). I brought my arduino and stepper-motor. But I spent a lot of the time there socializing, playing with other peoples' toys [6], and such. It's a cool space, and my life isn't compatible with spending much time there, but I'm glad to see it exists.

[5] but my optometrist's office is 5 minutes walk from my office; and they gave me a new lens to replace the one that was stuck in my eye. Oops, I wasn't going to describe it. Well there you go.

[6] the reprap was a surprise to see in person- by the end of the evening, it was working, and it did "print" a plastic part used to make itself. Re-reading reprap.org, I had forgotten they only produce 60% of their own parts- yes it's a toy, but it's a fairly cool toy.

I'm missing some stuff in this update, but that's what I get for not posting frequently enough.

There are moments I get, that the world is full of promise. Anything is possible.

In this one, I will attempt to re-join my LJ.

I've been following my friends-list for the last while, but one thing and another, I'd not had time to really figure out what I wanted to say in this space.

Over the last month, my overall mood has been grateful.

That's the main theme. There are sub-themes, including full of joy, awed, stressed, frustrated, and ow. And I could write a post about all of these, but I will instead try for a one-liner: joy at time with dan and with other friends; awe at wonderful theatre; stress from repercussions of having too much on my plate; frustration with "this should be easier"; and "ow" at my body. Each, a side-note to the main-theme of gratefulness- Life? It is good.

And I have been enjoying the nudging I've been getting (from friends, from God, from readings) that being grateful is a perfectly fine response.

It doesn't make for gripping reading, though; so let me tell you a story.

[oh geez, why did I write that? Now I've totally written myself into a corner, I haven't even come up with what story I'll tell.]

[Back from Quaker Meeting, a ride home with beartalon, and a bit of lunch...]

This story is about the future.

Last week at work I was emailing with the campus bookstore about their print-on-demand service. They have a book-printing machine, and I was curious if it was reasonable to print this for me. They quoted $50 setup, $19.95 to make the book. But, since I said that co-workers would probably want additional copies, he added they could waive the setup fee if they deemed the book worth keeping in their library. Sounded great; he'd talk to his boss; I'd get back to him when I needed the book...

On Thursday, when I was in the midst of finishing programming edits on this month's project, I got an email from the bookstore, "We've printed a sample. Come and take a look."

Oh. Oh no. As I told dawn_guy: that was so totally unfair, I didn't have time to do that, I had a million things to do.

So I was an adult, and kept fixing bugs, even though in the back of my head, there is a book that wasn't ordered on my behalf, it was printed and perfect-bound on my behalf, and it was just sitting there waiting for me to go collect it. So, ya, I'm a bit of a book nerd, and I wanted to go kick the book's tires.

Just before 5pm, I dropped by dawn_guy's office and said, "I need a walk. Wanna go down to the bookstore?" And we did. And the book machine was sitting there, and Sean showed me the sample he made, which was pretty much exactly like the PDF, a slightly oversize paperback book, with a black-and-white cover-page because we didn't give them a colour page to work from. And Dawn and I realized the bottom edge was off by a couple of millimeters, and he checked with a level and yup, the cutter had gotten a bit out of alignment. And I was craning my neck to get a better look at the machine behind the counter, so Sean asked me if I wanted to go back and look at it.

And he ran off a copy of Heart of Darkness while I was there, just to show how it works. And it looks more or less like the video- from when you press "print", it plunked out a book in less than five minutes. More or less indistinguishable from any paperback, except the colour cover felt warm, and not quite dry yet.

Which feels yet another step closer to Matter Compilers in various bits of science fiction.

As I remarked to Dawn, I have seen the future, and it is slightly tacky.

The book will serve well. It is a well-written manual (also published by O'Reilly Press) for the revision-control system called "Subversion". Which is why I made a bookmark last week to "Subversion Best Practices", a title that slightly disappointed peaceofpie when he saw what it really was. :)

Check out the video for a new painting and sketching app for the iPhone/Touch. Very neat looking. It's got: infinite zoom (vector graphics), free rotation, a clever palette, and brushes that seem to work very much like real brushes (blending, washes, translucency.)

If I had an iPhone, I would be all over it, even though I, um, don't really draw; and not just because I know the author. Who happens to have an art studio in town AND a long history with writing software for artists. So I know the next version of Paintbook is going be even more sophisticated.

Anyhow, happy Monday!
